1. What Changes Can You Make in Your Habits to Become More Environmentally Friendly? 

Ans. The following habits can be adapted to become more environmentally friendly: 

Use of plastic should be minimized and if used, try to reuse or recycle. 

Use water judiciously. 

Smart ways of disposal of waste should be adopted. 

Keep your surroundings clean. 

Do not litter public places.  

2. What Would be the Advantages of Exploiting Resources With Short-Term Aims? 

Ans. None is the advantage of exploiting resources with short-term aims. If exploitation of resources is done for short or long-term aims it will result in harming the environment and take a toll on nature’s health.  

3. How Would These Advantages Differ from the Advantages of Using a Long-Term Perspective in Managing Our Resources? 

Ans. Natural resources will last for generations to come if a long-time perspective is taken under consideration in managing our resources. Long-time management of resources ensures uniform distribution among the consumers.  

4. Why Do You Think There Should Be Equitable Distribution of Resources? What Forces Would Be Working Against an Equitable Distribution of Our Resources? 

Ans. Natural resources of the Earth must be distributed among the people uniformly so that each one gets his share of the resource. The forces working against an equitable distribution of resources are greediness of humans, corruption, and inequality.

1. Why should we conserve forests and wildlife? 

Ans. We should conserve forests and wildlife because: 

Forests are home to a large number of plants and animal species 

Forests maintain ecological balance and hence, are responsible for the regular cycle of seasons.

Wildlife is a part of our ecosystem and disturbing their population will affect the food chain. 

Besides, tribal populations depend on forests to conserve their culture and tradition.

2. Suggest Some Approaches Towards the Conservation of Forests. 

Ans. Following are some approaches towards the conservation of forests: 

By protesting against the cutting of trees people should show their participation in saving the forest. For example, Chipko Andolan 

More and more planting of trees should be done. The rate of afforestation should be greater than that of deforestation.

To catch wood smugglers government should take legal steps. 

1. Find Out About the Traditional Systems of Water Harvesting/management in Your Region.  

Ans. The use of tanks is one of the traditional systems of water harvesting used in our region. 

2. Compare the Above System With the Probable Systems in Hilly/mountainous Areas or Plains or Plateau Regions. 

Ans. Crescent-shaped earthen embankments are the water harvesting structures in the plains. These are mainly low, straight, and concrete. Whereas in hilly regions, kulhs is used for water harvesting which is the system of canal irrigation. Here the rainwater gets collected in a stream, from where it is then diverted into man-made channels down the hillsides. 

3. Find Out the Source of Water in Your Region/locality. Is Water from This Source Available to All People Living in That Area? 

Ans. The source of water in our region is a river. Yes, water from this source (river) is available to all the people living in that area.

Class 10 Science Sustainable Management of Natural Resources Notes and Questions

Need for Management of Natural Resources

We use various natural resources such as forests, wildlife, water, coal, petroleum etc, for our various needs. As the level of development increases, the rate of utilization of these natural resources also increases. A majority of these natural resources is exhaustible. Excessive use of these natural resources causes a negative impact on our environment. It releases pollutants that pollute the air, water, and soil. The use of these natural resources also leads to the degradation of the environment. We therefore need a systematic plan for the utilization and conservation of these natural resources. This is known as natural resource management.

Natural resource management is the optimum utilization of natural resources by maintaining the balance of natural environment for sustainable utilization and development.

Why do we need to manage natural resources?

We need to manage natural resources because of the reasons listed below.

• A majority of natural resources is limited
• Human population is increasing at a tremendous rate
• Utilization of natural resources is increasing at an exponential rate
• Need to conserve resources for future generations
• Equal distribution of resources for equal benefit
• Need to reduce the damage caused to the environment because of the over-exploitation and utilization of resources
• Waste generated from the utilization of these resources is to be safely disposed

Thus, a proper and planned utilization of natural resources is essential for sustainable development.

Sustainable development refers to a balance between natural resources, ecosystems, and the human requirement for resources, for the development and growth in the standards of living. Sustainable development also includes the safeguarding of our natural resources so that they are of use to the future generations.

The following table shows some of the problems arising from the over-exploitation of natural resources

The over-exploitation of resources and the related environmental problems are global problems. Therefore, there are many national and international laws for the protection of the environment. Several international organizations are also working toward the protection of environmental resources.

In addition to this, every country enforces its own laws and regulations for the protection of the environment. Let us know the objectives of a few of these laws.

One such movement in India is the Ganga Action Plan.

The Ganga is over 2500 km long and passes through the states of Uttarakhand, Uttar Pradesh, Bihar, and West Bengal. The major sources of pollution are garbage, excreta, untreated sewage, bathing, washing, immersion of ashes, and chemical waste from industries.

The objective of the Ganga Action Plan is to improve the quality of water by preventing pollution. It is a multi-crore action plan to clean up the Ganga.

Do You Know: About 60000 people bathe in the river Ganga daily, and 1 billion litres of untreated sewage is dumped daily into the river

Natural resources can be conserved by the three-R-method.

A particular method of conservation (reducing consumption, recycling or reusing) is more suitable for a particular natural resource.

For example, Petroleum and coal cannot be reused or recycled. Hence, reducing the consumption of petroleum and diesel is the only way in which these resources can be conserved.

Aluminum products are regularly used for wrapping food items and making soft drink cans etc. After using these products, we usually tend to throw them away as waste. This causes a huge loss of aluminum. It is a recyclable resource and hence, we must contribute towards the recycling of aluminum products by not throwing them away as waste materials. Similarly, paper is also recycled . Therefore, we should try and use recycled paper.

Jams and pickles are often packed in plastic bottles. Once these bottles are empty, we can use them for storing small things in our kitchens. This is an example of reusing materials. The reusing of these materials is advantageous as it does not involve any expenditure, unlike in the case of recycling of waste materials.

Importance and Conservation of Forest

Forests are rich in biodiversity, and are also a very important resource for human beings. Various life forms such as bacteria, fungus, ferns, flowering plants, insects, birds, reptiles etc. are abundantly found in forests. If the biodiversity of forests is lost, then it will have a negative impact on the ecological balance of our environment. We also use many products obtained from forests to meet our day-to-day needs.

The following table shows how forests are used in several ways to meet our needs.

Thus, individuals, governments, and industries are rightly called the stakeholders of forests as they are the main users of forests.

As a result of such a huge dependence on forest resources, forests are increasingly being exploited by humans for their needs. This is leading to a fast depletion of the forest cover. The exploitation of forest resources causes a loss of biodiversity, which adversely affects the balance of the ecosystem.

Biodiversity includes all marine and terrestrial organisms living in an area.

The biodiversity of an area is measured by counting the number of species found in that area. All organisms found in an area form an important part of the biodiversity of that area.

If the biodiversity of a forest is disturbed, then it can lead to serious consequences such as the extinction of valuable plant and animal species, soil erosion, flood, drought, and climate changes. These can lead to an ecological instability.

Do You Know:

The Pink-headed duck is a possibly extinct bird that was found in eastern India, Northern Myanmar, and Bangladesh. Its habitat was lowland, marshy pools in tall grass jungles. It was last seen in 1935. The cause of its possible extinction is the destruction of its natural habitat.

Another factor responsible for the loss of biodiversity is the period of British rule in India. During their stay in India, the British over-exploited and depleted the forests.

After independence, Indian government started developing monoculture forests (a forest which has only one plant species). Such forests do not have biodiversity and cannot fulfill the varied needs of the people who live in and around these forests.

The over-exploitation of forests has resulted in the depletion of this valuable natural resource. The resultant loss of biodiversity affects the balance of our ecology. Therefore, conservation of forests is very important.

Conservation of forests

Government and local people are now working toward the conservation of the depleting forests. Initially, environmentalists took up the task of conservation of large animals such as lions, tiger, elephants, and rhinoceros. Later, the need was felt to protect and conserve biodiversity as a whole.

There are various organisations that are set up across India to save forests and preserve wildlife. Some such organisations are

• Wildlife First
• Centre for Wildlife Studies (CWS)
• Tropical Research and Development Centre (TRDC)
• Sahyadri Wildlife and Forest Conservation Trust (SWIFT)
• Ashoka Trust for Research in Ecology and the Environment (ATREE)

The vast tracts of forests and wildlife in the 80 National Parks and 441 Wildlife Sanctuaries across India have been conserved with the effort of the Indian Government.

Every national park has been conserved along with the native flora and fauna. For example, the Kaziranga National Park is famous for the one-horned rhinoceros. It is also the natural habitat of elephants, tigers etc.

The government of India has also undertaken various projects to increase the population of natural flora and fauna of forests.

Silviculture has been taken up as an important program to replenish the depleting forests by planting more trees. The advantages of silviculture are listed below.

• It prevents soil erosion and floods
• It helps to maintain the water cycle on earth
• It produces huge amounts of raw materials for the industries

Active participation of local people to save forests is another activity toward the conservation of forests and wildlife. The following are some examples of people’s participation in the conservation and management of forests.

In 2001, the total forest cover in India was 675538 km 2 , which is 20.55% of the total land surface area of India.

Steps To Make Water Available To All

Water is a necessity for every form of life. It is used for domestic purposes, irrigation, navigation, industrial purposes, etc. Areas that encounter acute shortage of water are also areas that face severe poverty and underdevelopment.

There are various sources of water. Rainfall is one of the primary sources of water. Our country receives rainfall during the monsoon season. An adequate amount of rainfall helps to increase the level of groundwater.

However, despite water being abundantly available, we have failed to sustain its availability throughout the year because of several reasons. Some of these are listed below.

• In order to meet the demands of a growing population , water is overdrawn from water bodies such as ponds, lakes, rivers, etc. This results in the drying up of these sources of water.
• The amount of groundwater being drawn for use by humans is more than the amount of water being replaced through rainfall. This has resulted in the depletion of groundwater. In some areas, the groundwater level has gone down drastically.
• Very little water seeps through the ground because of a lack of adequate vegetation cover.
• The availability of usable water resources is diminishing as a result of an increase in water pollution levels . This is primarily caused by the discharge of sewage and industrial wastes into water bodies.

In India, the irrigation and conservation of water through the construction of dams, canals, and tanks are age-old practices. These methods of irrigation and conservation of water are based on the traditional models.

These practices are essentially governed by the requirements of the local people, who try to ensure that their minimum water requirements for agriculture and other daily requirements are met throughout the year.

The coming of the British to India saw the construction of large scale dams and big canals covering long distances. These large scale irrigation and water conservation methods are not based on the traditional models. The administration and governance of such large scale projects are in the hands of the government and not in the hands of the local people. This causes improper and unequal distribution of water in certain areas. People living near a source of water i.e., near a canal or a dam grow water-intensive crops such as paddy and sugarcane while those living down the stream do not get any water.

Rivers, lakes, ponds, oceans, and glaciers are some of the other sources of water. These sources are rapidly diminishing because of an increase in population and rising levels of water pollution.

The phenomenon of global warming is primarily the result of industrialization and deforestation. It disturbs the natural water cycle, which results in changes in the pattern of rainfall.

Methods of conservation

Rainwater is essential for ensuring the availability of usable water. Let us watch the following animation to understand why rainwater harvesting is important and how it can be done?

Rainwater harvesting has been in practice in rural India since a very long time.

Small pits, lakes, earthen dams, sand and limestone reservoirs, and rooftop water collecting units are some of the well-known structures that are used for collecting rainwater. The underlying concept is to make rainwater percolate below the ground, so that the level of groundwater gets replenished.

The following table lists the local names of some water harvesting structures.

The traditional rainwater harvesting method used in Rajasthan is based on the principle of harvesting rainwater in farmlands.

In this method, saturated water is used for crop production and the surface run-off water is harvested for agriculture.

This method mainly consists of an earthen embankment (known as khadin), built across the lower slopes of the hills.

A cemented wall (known as khadin bund) is built to hold the water in the khadin.

Advantages of rainwater harvesting

• Water does not evaporate. Instead, it percolates into the ground, thereby resulting in the recharging of wells.
• The stored water provides moisture to the vegetation in and around the area.
• Rainwater harvesting improves the quality of groundwater by the process of natural filtration of fluorides, nitrates, and salts. This method of storing and utilizing water prevents soil erosion and flooding. Thus, it is an eco-friendly method.
• The stored water does not provide a breeding ground for mosquitoes and microorganisms, unlike the stagnant water in ponds and lakes.

River water

River is an important source of water. The source of a river could be a spring, a lake, a glacier, or surface run-offs. Rivers provide water to a large area as they travel long distances in the course of their flow. However, an excessive flow of water in rivers results in floods. River water is managed by building dams.

What are dams?

Dams are constructed across rivers to control the flow of water in them. The lock-gates in dams are used for checking and controlling this flow of water.

How are dams useful?

Dams provide a range of economic, environmental, and social benefits to human beings. Some of these are listed below.

Water supply: The water stored in dams is used for irrigation throughout the year, irrespective of the season. For example, the Indira Gandhi Canal originates in Bhakra dam and provides water to several areas in Rajasthan.

Hydroelectric power: Dams are also equipped with turbines and generators to produce hydroelectricity.

Flood control: Floods can be controlled by checking the flow of water in a river.

Recreation: Dams provide opportunities for water skiing, setting up of camping resorts, and boat launch facilities.

Waste management: Dams contribute to environmental protection through the retention of hazardous materials and detrimental sedimentation.

Disadvantages of dams

There are certain disadvantages associated with the construction of dams across rivers.

Environmental problems: The construction of dams across rivers leads to deforestation, which results in the loss of biodiversity. This creates a disturbance in the natural ecosystem.

Social problems: The construction of dams involves the building of large reservoirs. In some cases, constructing a reservoir may result in the flooding of nearby towns and villages. A large number of people are displaced as a direct consequence of the construction of reservoirs. In such cases, the government rehabilitates the people of these areas, which in itself is a huge task.

Economic problems: The construction of dams requires huge amounts of monetary investments. A dam does not become profitable until it starts generating electricity.

As a result of all these problems, there is a strong opposition to the construction of large dams. The opposition to the construction of the Tehri dam over the river Ganga and the Narmada Bachao Andolan (a protest against the proposed increase in the height of the Sardar Sarovar Dam over the river Narmada) are examples of such opposition.

6. What is the composition of LPG? Ans.  Propane, butane and various mixture of other gases.

2.TOPIC-OZONE

Read the following section of an article about the ozone layer. The atmosphere is an ocean of air and a precious natural resource for sustaining life on the Earth. Unfortunately, human activities based on national/personal interests are causing harm to this common resource, notably by depleting the fragile ozone layer, which acts as a protective shield for life on the Earth. Ozone molecules consist of three oxygen atoms, as opposed to oxygen molecules which consist of two oxygen atoms. Ozone molecules are exceedingly rare: fewer than ten in every million molecules of air. However, for nearly a billion years, their presence in the atmosphere has played a vital role in safeguarding life on Earth. Depending on where it is located, ozone can either protect or harm life on Earth. The ozone in the troposphere (up to 10 kilometers above the Earth’s surface) is “bad” ozone which can damage lung tissues and plants. But about 90 percent of ozone found in the stratosphere (between 10 and 40 kilometers above the Earth’s surface) is “good” ozone which plays a beneficial role by absorbing dangerous ultraviolet (UV-B) radiation from the Sun. Without this beneficial ozone layer, humans would be more susceptible to certain diseases due to the increased incidence of ultra-violet rays from the Sun. In the last decades the amount of ozone has decreased. In 1974 it was hypothesized that chlorofluorocarbons (CFCs) could be a cause for this. Until 1987, scientific assessment of the cause-effect relationship was not convincing enough to implicate CFCs. However, in September 1987, diplomats from around the world met in Montreal (Canada) and agreed to set sharp limits to the use of CFCs.

• 1. Ozone is also formed during thunderstorms. It causes the typical smell after such a storm. the author of the text distinguishes between “bad ozone” and “good ozone”. In terms of the article, is the ozone that is formed during thunderstorms “bad ozone” or “good ozone”? Choose the answer and the explanation that is supported by the text

Ans. Full credit: B. Bad. It is formed in the troposphere.

2. “Without this beneficial ozone layer, humans would be more susceptible to certain diseases due to the increased incidence of ultra-violet rays from the Sun.” Name one of these specific diseases.

Ans. Full credit: Answers which refer to skin cancer.

3.TOPIC- ACID RAIN

Below is a photo of statues called Caryatids that were built on the Acropolis in Athens more than 2500 years ago. The statues are made of a type of rock called marble. Marble is composed of calcium carbonate. In 1980, the original statues were transferred inside the museum of the Acropolis and were replaced by replicas. The original statues were being eaten away by acid rain.

Question.Normal rain is slightly acidic because it has absorbed some carbon dioxide from the air. Acid rain is more acidic than normal rain because it has absorbed gases like sulphur oxides and nitrogen oxides as well. Where do these sulphur oxides and nitrogen oxides in the air come from? Ans.  Responses that mention any one of: car exhausts, factory emissions, burning fossil fuels such as oil and coal, gases from volcanoes or other similar things. Burning coal and gas. Oxides in the air come from pollution from factories and industries. Volcanoes. Fumes from power plants. They come from the burning of materials that contain sulfur and nitrogen. – Responses that include an incorrect as well as a correct source of the pollution. Fossil fuel and nuclear power plants. [Nuclear power plants are not a source of acid rain.] The oxides come from the ozone, atmosphere and meteors coming toward Earth. Also, the burning of fossil fuels. – Responses that refer to “pollution” but do not give a source of pollution that is a significant cause of acid rain. Pollution. The environment in general, the atmosphere we live in – e.g., pollution. Gasification, pollution, fires, cigarettes. Pollution such as from nuclear power plants.

Question. The effect of acid rain on marble can be modelled by placing chips of marble in vinegar overnight. Vinegar and acid rain have about the same acidity level. When a marble chip is placed in vinegar, bubbles of gas form. The mass of the dry marble chip can be found before and after the experiment. A marble chip has a mass of 2.0 grams before being immersed in vinegar overnight. The chip is removed and dried the next day. What will the mass of the dried marble chip be? A. Less than 2.0 grams B. Exactly 2.0 grams C. Between 2.0 and 2.4 grams D. More than 2.4 grams Ans.  Full credit: A. Less than 2.0 grams

Management of Natural Resources CBSE Class 10 Science Revision Notes Chapter 16

Natural Resources are obtained from earth and its environment. Natural resources are classified as-

Renewable resources which are continuously available for use. They do not get exhausted with time. For Example , Sunlight, Wind, Water etc.

Non-renewable Resources are those which gets exhausted with time. They are present in limited amount on the earth. For Example , Minerals.

Natural Resources are also classified as biotic and abiotic resources.

Biotic Resources can be obtained from forests, animals etc. For Example , Fossil Fuels.

Abiotic Resources are those that come from non-living and non-organic material.

There are three important terminologies used which are as follows-

Refuse : Say no to things that are offered to an individual. For Example , an individual say no to buy plastic products.

Reduce : Minimize the use of anything. For Example , minimize the use of fans, tubelights etc.

Reuse : To use the things again and again is defined as reuse.

Repurpose : When a particular thing cannot be used for a purpose, it can be used for another purpose.

Recycle: When the material can be used to make the needed things.

Why do we need to manage the resources?

We need to manage the resources because they are present in limited quantity. With the increase in population, the demand for resources are increasing. So, there is a need to manage the resources to minimize their use and preventing the exploitation of resources.

Forests and Wildlife

Forests are biodiversity hotspots. Biodiversity is defined as different types of organism present on the earth. The main aim of conservation is to preserve the biodiversity. The loss of biodiversity will lead to loss of ecological stability.

Stakeholders

Stakeholders who are-

They are the people living around the forests are dependent on forest and its products.

Forest department of the government owns the land and also control the resources from forests.

Industries that use forest produce . For Example Timber, Paper, Resin, Gum medicines, Sports equipment industries.

Wildlife and natural enthusiast who want to conserve the nature.

Bamboo is used to manufacture huts, baskets and also for food storage. Implements used in agriculture, fishing is largely made up of wood. The government of India has recently instituted an Amrita devi bishnoi national award for wildlife conservation in the memory of an Amrita Devi bishnoi who sacrificed her life to protect the trees in 1731.

Management of Forest

Local communities have been working traditionally for conservation of forests and trees. Magsaysay Award recipient Sunderlal Bahuguna gave momentum to the Chipko Andolan. The Chipko Andolan was started in Reni in Garhwal.  It was started by villagers especially by women at Reni village who tried to stop the commercial wood contractors from cutting the tree by hugging the trunk of the trees.

People Participation in the Management of Forests

The acceptance of locals who live in harmony with natural resources is vital for forest conservation measures. In 1972, the West Bengal forest department found that they have failed in maintaining the degraded Sal forests. Surveillance and policing had led to complete alienation of the people which led to clashes between forest officials and villagers. So, to overcome this, department was forced to changed the strategy. Forest officer A.K. Banerjee involved villagers in protection of 1272 hectares of badly degraded Sal forests in Arabari forest range of Midnapore district. In return he allowed villagers to collect fuelwood and fodder on payment of nominal fee.  Also 25% of final harvest was given to village community.

Methods of Forest Conservation

One of the most common method of forest conservation is silviculture. It is a method in which trees are grown and cultivated.

Social forestry deals with the management and protection of the forest.

Agroforestry includes land management for the cultivation of trees or shrubs.

Red Data Book

It is a document for recording the list of the endangered and rare species of animals, plants, fungi as well as some local species also.

Water for all

Water is required for fulfilling the basic needs of individuals. Human activities have altered the availability of water in various regions. Rain in India are due to monsoon. Common irrigation methods such as dams, canals and tanks are used in various parts of India. These methods are maintained by local people. This helps in storing water which can be used in agriculture. Not only in agriculture, daily needs of the common people can be met through this water.

Ganga Action Plan

This plan was launched by Shri Rajeev Gandhi in 1986. It is to improve the water quality of ganga by treatment, diversion and interception etc. It also includes treatment of domestic sewage and industrial effluents before releasing them into water bodies.

Large dams are made to store water that can be used in irrigation, in generating electricity etc. Indira Gandhi canal in Rajasthan areas has helped a lot in bringing greenery in different regions.

Dams control floods, provide water supply, electricity, waste management, recreation and wildlife habitat etc.

Criticism about large dams addresses three problems in particular- social problems, economic problems and environment problems

Construction of dams causes problems such as excessive sedimentation, water logging, sudden floods, soil erosion, large scale deforestation, health hazards, loss of livelihood etc.

Ancient Method of Watershed Management System

Different methods of watershed management system are known since ancient times. One of the method known as Khadins in Rajasthan which consists of a long earthen embankment built across the lower hill slopes. The area enclosed by the embankment is called as ‘ bund ’ which collects huge amount of rainwater which flows down the slopes. Subsequently this water saturated land is used for crop production.

Figure 1: Khadin in Rajasthan- An ancient  method of watershed management.

Talabs are other mode of watershed management system known so far. It stores water for drinking and household consumption purposes. Others include kulhs in Himachal Pradesh,, Ahar and  Pynes in Bihar, Eris in Tamil Nadu, Bundhis in Madhya Pradesh, Surangams in Kerala etc.

Coal and Petroleum

They are the non-renewable natural resources.

Coal is formed by the remains of the trees buried inside the earth.

Petroleum is formed by the bacterial decomposition of dead plants and dead animals. High pressure and temperature are needed for the formation of petroleum.

Both coal and petroleum are fossil fuels.

They are getting used up at higher rate, so there are more chances that they get exhausted soon.

Disadvantages of Fossil Fuels - Burning of fossil fuels release large amount of carbon-dioxide, sulphur dioxide and other harmful gases. This causes air pollutions and the harmful effects of air pollution. This also raises the earth temperature and thus leads to global warming.

Steps to minimize the pollution from Fossil Fuels

Reduce the use and burning of fossil fuels.

Use of CNG in transport vehicles to reduce pollution.

Alternative sources of energy such as Hydroelectricity, nuclear, solar, wind power and biogas should be used.

Also, students may come across a few of these questions in the board exam.

Important Questions for Class 10 Science Chapter 16 – PDF

1. List any two measures that you suggest for better management of water resources.

Answer: Two measures for better management of water resources are:

(i) Adopting rainwater harvesting techniques so that we can capture and store rainwater for future use. Construction of dams to store water for irrigation purposes.

(ii) At individual level, we can repair faulty taps, pipes and prevent water loss. We should close the water taps when not in use.

2. Why does the management of natural resources require a long-term perspective?

Answer: Management of natural resources requires a long-term perspective so that it helps in sustainable development and it should be available for our future generations too.

Exploiting resources for long-term prospective meet the needs of future generation also. The management of natural resources for future use is a sustainable practice. The judicious use of natural resources in present generation enables the future generation too, to use them for their benefits.

3. State what happened when the “Chipko Movement” spread across communities and media.

Answer: Chipko movement was originated from a small village Reni in 1974 where a group of women under the leadership of Gaura Devi protest against indiscriminate felling of trees by hugging them. The Chipko movement spread slowly to other parts under the leadership of Shri Sunderlal Bahuguna of Silyara in Tehri region. Chipko movement is the movement where people form a circle around the tree and hug them to prevent falling of trees. The local people of Tehri-Garhwal district of UP realize the importance of forests and protest against felling of trees as well as giving forest products to other regions.

It helped in saving trees which ultimately result in conserving soil and water sources which maintain balance in our nature.

4. “Reuse is an important step in saving environment”. Justify.

Answer: Reuse is considered better than recycling as recycling consume some energy to generate new things which is not seen in case of reuse. Reuse prevents environment pollution by not creating any waste. Reuse also saves money as material is used again without any process.

5. List any two sources which add greenhouse gases to the environment.

Answer: Two sources are burning of fossil fuels and exhausts from automobiles. Both produce carbon dioxide gas which is a major greenhouse gas.

6. How does mining cause pollution?

Answer: Mining causes soil erosion, loss of biodiversity. The chemicals released from mining activities cause contamination of soil, groundwater, surface water. Dust from mining causes air pollution. Mining activities too cause noise pollution. In this way, mining practices cause air, water, soil and noise pollution.

7. Every one of us can do something to reduce our consumption of various natural resources. List four such activities based on 3-R’s approach.

Answer: Four such activities are-

(i) By reusing things instead of throwing away. Example – old clothes, toys etc. can be given to needy people, plastic bottles of jam, pickles can be used to store other things etc.

(ii) We can recycle things like paper, plastics, metals, glass etc.

(iii) We can use waste water that is produced from water purifier in watering plants, moping floor, cleaning vehicles etc.

(iv) Using CFLs bulbs, fluorescent tubes which consume less energy instead of conventional bulbs or tubes.

8. Suggest two ways to conserve forests.

Answer: Two ways to conserve forests are-

(i) Large-scale afforestation programmes.

(ii) By implementing law for severe punishment to anyone who is involved in illegal cutting down of trees.

9. Give an example to show that the prejudice against the traditional use of forest areas has no basis.

Answer: The Great Himalayan National park contains Alpine meadows within its reserved areas which were once grazed by Nomadic shepherds but this practice has been stopped now. So, grasses have become very tall now which then fall over and prevent fresh growth in alpine meadows. This is an example which shows that the prejudice against the traditional use of forest areas has no basis.

10. Name the old-age water harvesting techniques/structures of Rajasthan still in use today.

Answer: Khadins, tanks and nadis are the old-age water harvesting techniques/structures of Rajasthan still in use today. Khadins is a traditional way of harvesting rainwater and it is mainly followed by people of Rajasthan. These are very long earthen embankments which are built

across the lower edge of the sloping farmlands which are called bund. Rainwater flows down the slopes and fills the bunds to form a reservoir. Pathways are made from bund to nearby well which are mainly dug behind the bund where water seeps and fills the wells.

11. State two reasons of launching the “Ganga Action Plan”. Which bacteria was found in Ganga’s water indicating contamination?

Answer: Two reasons for launching Ganga Action plan are-

(i) To improve quality of water of River Ganga.

(ii) To reduce the pollution load of River Ganga and make people aware of preventing pollution of Ganga river. This plan was launched in 1985 by Mr. Rajeev Gandhi. Coliform bacteria were found in water of Ganga indicating contamination.

12. State the meaning of biodiversity hotspots. What is the criteria of measuring biodiversity of an area?

Answer: Forests where a large number of flora and fauna species are found are termed as biodiversity hotspots. The criteria for measuring biodiversity are- (i) Number of species found in that area. (ii) Range of different life forms like algae, bacteria, mosses, flowering plants, insects, animals, birds etc.

13. What do the three R’s refer to? Explain the main purpose of following these strategies in daily life.

Answer: The three R’s means Reduce, Reuse and Recycle. Reduce means less use of resources like switching off lights, fans, television, computers, music players when not in use. Closing the taps while brushing teeth, repairing the faulty taps from which water leaks. Reuse means using things again and again like we can write on both sides of a paper, we can give our unused and old things to needy and poor people, bottles of jams, jellies, pickles when finished can be used to

store other things etc. Recycle means using recycling technology new things can be produced from old ones like old newspaper, glass bottles, plastics etc. 3R’s approach is the best technique to save our environment.

14. List four benefits that could be provided to the local people in Arabari forest range.

Answer: Four benefits provided to local people were employment in silviculture and harvesting operation, collection of firewood, collection of fodder at nominal price, use of forest products etc.

15. Mention two reasons to explain why forests and wildlife should be conserved.

Answer: Wildlife maintains an ecological balance of nature. It provides a great biological diversity. Many valuable products like musk, ivory, leather etc. are obtained from them. Forests provide us various valuable products like honey, medicines, lac, gums, resins, wood, prevent soil erosion and flood, brings rainfall, release oxygen to atmosphere which is a life supporter. Forests are habitat of variety of living organisms. Loss of biodiversity would lead to ecological imbalance so we need to conserve forests and wildlife.

16. Why management of natural resources should ensure equitable distribution of resources?

Answer: There should be an equitable distribution of resources because everyone has equal rights to use natural resources and gets benefits from them. Everyone whether rich or poor has equal rights to get benefits from natural resources. Geographical factors and economic factors are the forces working against an equitable distribution of our resources. The rich and powerful people take advantage and get more benefits by using resources as compared to poor people. Over exploitation and mismanagement of resources also works against equitable distribution of our resources. So natural resources should be managed in such a way that everyone should get equal benefits from our natural resources.

17. Local people around forests are referred to as “stakeholders” for conservation of forests. Give reasons.

Answer: Local people know the practices to use these resources in a sustainable manner without causing any harm or damage to environment. Because as we have seen in our past how local people protect the Sal forests of Arabari and tribal women of Tehri-Garhwal district of UP protest against the felling of trees by hugging them. So the local people who live in or around forest are referred to as “stakeholders” for conservation of forests.

18. Sustainable development implies a change in all aspects of life. Justify the statement.

Answer: (i) Sustainable development implies various forms of growth in all levels like agriculture, ecological, social, natural resources etc. and meets the current basic needs. (ii) It helps in preserving resources for future generations too. (iii) It leads to conservation of environment and leads to economic development.

19. What is the aim of water harvesting?

Answer: The aim of water harvesting is to collect and store rainwater by using special techniques for future use when there is shortage of water or during non-rainy days. This water can be used for irrigation or it can be purified and can be used for drinking and other domestic purposes.

20. “Burning of fossil fuels results in global warming.” Justify the statement.

Answer: Burning of fossil fuels releases various types of gases like carbon dioxide, oxides of sulphur, oxides of nitrogen etc. Carbon dioxide is a greenhouse gas and when released in large quantities formed as a layer on our atmosphere causing greenhouse effect. It traps the sunlight rays inside the surface of earth thus the temperature of earth increases. Hence the consequence of greenhouse effect is global warming. Besides the oxides of sulphur, oxides of nitrogen etc. which are released into the atmosphere are the main causes of acid rain.

21. The construction of large dams leads to (i) social, and (ii) environmental problems. List two problems in each case.

Answer: (i) Social problems – Vast area of land get submerged under water so many people become homeless. It also leads to unequal distribution of water. People close to the source will get enough water for agriculture whereas those far from the source cannot get sufficient water.

(ii) Environmental problems – Large-scale deforestation, loss of flora and fauna of that particular area, displacement of large number of people living in that area etc.

22. “Industrialization is one of the main causes of deterioration of environment”. List any four reasons in favor of this statement.

• Industrialization causes air, water, soil and noise pollution.
• Effluents released from industries to nearby water bodies destroy the quality of water.
• Toxic gases release into air pollutes it and causes many respiratory disorders.
• Constant running of heavy machines causes noise pollution.

23. Mention any reasons for which environmentalist protested against raising height of the “Sardar Sarovar Dam” on river Narmada.

Answer: The problems which arise due to construction of big dams are:

(i) Social problems: Vast area of land get submerged under water so many people become homeless. It also leads to unequal distribution of water. People close to the source will get enough water for agriculture whereas those far from the source cannot get sufficient water.

(ii) Economic problems: It involves a huge expenditure and low benefits as compared to the cost.

(iii) Environmental problems: Large-scale deforestation, loss of flora and fauna of that particular area, displacement of large number of people living in that area etc.

24. What are fossil fuels? How are they formed?

Answer: Fossil fuels are obtained by degradation of dead remains of plants and animals which are buried under the surface of earth over a million years ago. They are called so as they are produced by degradation of biomass over a million years ago. They are an important source of fuels. The two fossil fuels are coal and petroleum.

25. List three reasons to justify the need to manage the available resources carefully.

Answer: Three reasons are- (i) We should manage our available resources carefully so that our future generations can take benefits from them. (ii) Every one of us can take benefits from them without any shortage. (iii) Some resources are non-renewable so we should use them wisely without leading to any exhaustion of these resources.

26. List any four human activities responsible for the pollution of river water.

Answer: Four human activities that cause pollution of river water are-

• Disposal of sewage, human unburnt corpses.
• Bathing and washing of clothes.
• Bathing of domestic animals
• Immersion of ashes, garbage disposal.

27. We should use coal and petroleum judiciously. Why? State any four reasons.

Answer: We should use them judiciously because-

(i) They are an important source of fuels. Petroleum products like petrol, diesel etc. are used as fuel in automobiles. Coal is used in thermal power plants to generate electricity and also used as a fuel for domestic purposes.

(ii) They took millions of years to get formed hence if consumption will over exceed it may lead to exhaustion of these resources.

(iii) We should use them judiciously so that our future generations can take benefits from them.

(iv) Burning of these fuels cause pollution, global warming so we should use them wisely.

Sustainable Management of Natural Resources Class 10 Project

Introduction.

Natural resources refer to the entire natural environment that sustains human life and helps to produce the necessities and comforts that people need. These resources can be found on earth and meet human requirements. A natural resource is something that originates from the natural world and is used by humans. Some examples of natural resources are oil, metals, natural gas, etc. Other natural resources include soil, air, water, and sunlight.Natural resources are essential to human welfare. We need natural resources to meet our daily requirements. Let’s go through the management of natural resources class 10 in detail.

Pollution in River Ganga

• The Ganga serves as a sewage disposal site for more than a hundred cities dispersed throughout the states of West Bengal, Bihar, and Uttar Pradesh. The river has turned into a drain due to the disposal of untreated sewage. 
• The toxicity of the water affects the vegetation and animals of the river system.
• The Ganga Action Plan (GAP) project was started in 1985 to improve the poor water quality of the Ganges River.

Five R’s to Save the Environment

Refuse: Saying no to activities that will harm our planet or declining stuff you don’t need is a better way to save our environment. Avoid single-use plastic carry bags and harmful items that are dangerous for the environment.

Reduce: This step means using less. For instance, avoiding food waste, turning off switches to conserve electricity, fixing leaky faucets to save water, and minimising the amount of water used for bathing.

Reuse: This means reusing an item rather than throwing it away. Many things cannot be recycled or require a lot of energy; instead, we can utilise them for other purposes. For e.g., reusing plastic bottles and cutlery. 

Recycle: Recycling items such as scraps of paper, plastic, glass, or metal. 

Repurpose: This means that when a product can no longer be used for its intended function, consider using it in a different way. For instance, you can plant small plants in used plastic bottles.  

Need to Manage Natural Resources

• Natural resources are being destroyed at an alarming rate as a result of the growing population and the rising demands of changing lifestyles. Resource management must be a fundamental aspect of our society in order to ensure the equitable and sustainable allocation of resources and the minimisation of environmental harm.
• We must use our natural resources wisely because they are finite, and their management demands long-term thinking to last for future generations. This is known as Sustainable management of natural resources.
• The proper management of natural resources prevents their exploitation by taking into account a long-term perspective.
• All people can profit from the use of natural resources if they are distributed fairly through effective management.
• The correct management will examine the environmental harm brought on by the “extraction” or “use” of natural resources and find measures to reduce this harm.
• As the population grows, there is a greater demand for resources, which are being used up exponentially faster.
• In order to meet demand, industries are being forced to plunder our natural resources.

Forest and Wildlife 

• Forests are hotspots for biodiversity. The number of species of various life forms, such as fungi, bacteria, insects, plants, and animals that provide energy, constitutes an area’s biodiversity.
• A hotspot is a region rich in biological diversity.

Stakeholders 

Forest stakeholders are the people who depend on forest products and spend their lives near the woods. Indian government’s Forest Department is the land and resource owner of forest land. Industrialists use forest products to make goods. For example, Tendu leaves are used by industrialists for bidis and paper mills. They share responsibility for preserving nature in its pristine state, such as conservationists and animal enthusiasts.

Management of Forests

• Afforestation for the growth of forests on unused, bare land without protection is a must. Van Mahotsava is a movement to plant trees that are carried out by both governmental and non-governmental organisations twice a year (in February and July).
• Reforestation is necessary to establish forest cover in an area that has suffered damage.
• The amount of grazing should also be reduced. 
• Deforestation to remove, reduce, or degrade the region’s forest cover. 

Chipko Movement

• The conflict between local residents and industrialists in the 1970s led to the Chipko Andolan (also known as the “Hug the Trees Movement”).
• It originally originated in the Himalayan region of Reni Garhwal.
• The government was forced to reconsider how it managed forest resources as the campaign quickly acquired support and media attention. For instance, West Bengal’s Sal Forest was protected in 1972.
• Local participation is crucial for the management of forest resources.

Sustainable Development

• Stakeholders of forest resources must be satisfied for there to be sustainable development.
• Contradictions between local residents and industrialists result from companies utilising wood at rates substantially below those set by the market.
• The Arabari forests in West Bengal are highly renowned for being protected areas. Locals helped to build a community and cooperate with the village police and forest officials to make sure that there was no illegal deforestation or animal hunting, or land poaching, which helped the forest gain popularity.

Water Resource 

• All terrestrial life requires water to survive.
• Water scarcity causes severe poverty. 
• Due to the loss of vegetation and the emission of industrial effluents, the groundwater level does not rise despite the monsoon.
• Decrease in freshwater that can be used as a result of water table destruction and water cycle disruption.

Benefits of Dams

• They are used in watering crops through a canal system. Dams guarantee year-round water supply to agricultural areas and aid in increasing agricultural output.
• After the proper treatment, pipes deliver water from a dam to residents of towns and cities. By building dams, the area is guaranteed a steady flow of water.
• Electricity is produced from the dam water. As it pours over the dam, water drives turbines that power electric generators.

Water Harvesting 

The practice of collecting rainwater and storing them for future use is known as water harvesting. The major objective behind this age-old practice is to replenish the groundwater below as well as to hold the surface water.

Benefits of collecting water:

• Refuels wells and helps flora get moisture that helps in their growth. 
• It does not offer mosquito breeding grounds.
• The level of the groundwater rises.

Coal and Petroleum

The Earth’s crust contains fossil fuels like coal and petroleum. They are finite and non-renewable resources.

• Coal: This fossil fuel is made from the building up of compacted plant remnants. This flammable fossilised rock is used for industrial purposes, cooking, heating, etc. Thermal power plants require coal.
• Petroleum: Petroleum, a different kind of fossil fuel, was created in the past (approx. 10 to 20 billion years ago) from plant and animal remains. It is a mineral fuel that is found in sedimentary rocks. It is mainly used in transportation. Other uses of this fuel include agricultural operations, generators, and other businesses. 

Need to Conserve Natural Resources

• Decomposing vegetation usually makes fossil fuels. Created over millions of years, they have a significant amount of carbon.
• One drawback of these fossil fuels is that they produce hazardous gases. By polluting the environment, they cause global warming.

Simple Choices for Energy Conservation

• Choosing public transport to reduce vehicle numbers
• Opting for LED bulbs that conserve energy
• Taking the stairs

We hope your “sustainable management of natural resources class 10 project” is successful. Let’s strive to preserve our mother nature! There can be used as sustainable management of natural resources class 10 notes as well.

Short Answer Questions

25. Prepare a list of five items that you use daily in the school. Identify from the list such items that can be recycled.

Paper, rexin bag, blade, pen, plastic box, scale, eraser, compass and dividers (metallic), steel lunch box, steel spoon.

Paper, blade, plastic box, eraser, compass, steel lunch box and steel spoon can be recycled

26. List two advantages associated with water harvesting at the community level.

Advantages associated with water harvesting at the community level are as follows

• Water harvesting increases the level of groundwater.
• Water harvesting keeps the water on the top layer of soil and thereby reduces the loss of water by evaporation.

27. In a village in Karnataka, people started cultivating crops all around a lake which was always filled with water. They added fertilisers to their field in order to enhance the yield. Soon they discovered that the waterbody was completely covered with green floating plants and fishes started dying in large numbers.

Analyse the situation and give reasons for excessive growth of plants and death of fish in the lake.

During rains fertilizers used for agriculture spreads to the lakes. Fertilisers contain phosphates and nitrates by which water body became enriched with these chemicals. These chemicals promote excessive growth of aquatic plants and the surface of the water was completely covered with plants. (eutrophication)

Depletion of light in the water body and insufficient availability of dissolved oxygen and nutrients resulted in the death of fish.

28. What measures would you take to conserve electricity in your house?

Following are the measures to conserve electricity in your house

• Replace all the incandescent bulb by LED bulbs
• Switch off the fan and light when the room/house is vacant.
• By keeping windows open light will be allowed to enter the house thereby reducing the usage of light during day time.
• Reduce usage of Air conditioners and coolers.

29. Although coal and petroleum are produced by degradation of biomass, yet we need to conserve them. Why?

We need to conserve coal and petroleum because they take millions of years to form. Usage of petroleum is more compared to the formation rate and they may get depleted. Hence it is very necessary to consume them.

30. Suggest a few measures for controlling carbon dioxide levels in the atmosphere.

• Use public vehicle to reduce the vehicle pollution.
• CNG or other clean fuels should be used.
• Manure should be prepared from garbage rather than burning it.
• Planting more trees will reduce the carbon-di-oxide level in the atmosphere.

31. (a) Locate and name the water reservoirs in Figures16.1 (a) and (b).

(b) Which has an advantage over the other and why?

• Figures16.1 (a) is a pond ecosystem and Figures16.1 (b) is an underground waterbody
• Groundwater body has more advantages than the pond ecosystem for the following reasons

Water will not evaporate

Water will not spread out to recharge wells. Provides moisture for a wide area.

Water will get contaminated from animal and human waste.

They will no breeding of insects.

Long Answer Questions

32. In the context of conservation of natural resources, explain the terms reduce, recycle and reuse. From among the materials that we use in daily life, identify two materials for each category.

Reduction of usage of material or commodity such as e.g electricity and water

Recycle is sending back the used good to manufacturer to use the material to produce some other byproduct.

e.g., plastic cups and buckets, glass tumbler, paper, metal objects

Reuse is the repeated usage of the same material instead of throwing it out. e.g., used envelopes, plastic carry bags, bottles of jam.

33. Prepare a list of five activities that you perform daily in which natural resources can be conserved or energy utilisation can be minimised.

(a) Unused water in the water bottle may be used for watering plant

(b) Close all the taps before you go to sleep.

(c) Avoid using a hosepipe for watering plants

(d) Wash vehicles only when they are dirty

(e) Use fan and light only when required

(f) Use solar water heating devices

(g) Use CFL in place of conventional bulbs/tubes

34. Is water conservation necessary? Give reasons.

Water is a basic necessity for all terrestrial forms of life. Life is not possible without water as it is necessary for all the life process.

3/4 th of the earth is filled with water but most of it is in the form of water. Hence we cannot use that water for our livelihood. We need fresh and clean water for our survival. Less than 1% of the total water on earth is freshwater. Hence available water is very less.

With the increase in population, our water needs also increase. Due to this water is overexploited and in few places, people suffer from shortage of water. Hence to save the life water conservation is necessary.

35. Suggest a few useful ways of utilising wastewater.

Following are the useful ways of utilising wastewater.

(a) Wastewater can be used to recharge the groundwater

(b)Wastewater can be used for irrigation

(c) treated municipal water can be used for washing cars, watering the gardens

(c) certain pollutants in sewage water can become fertiliser for various crops.

36. What is the importance of the forest as a resource?

Following are the importance of the forest as a resource.

(a) Forests provide Habitat, food, protection to wildlife.

(b) Forests help in balancing CO2 and O2 of atmosphere.

(c) Forests improves water holding capacity of soil.

(d) Forests regulates water cycle.

(e) Forests are the source for all essential commodities like fuelwood, timber pulp and paper etc.

(f) forests provides useful products like fruits, resins, gums, essential oils, bidi wrapper etc.

37. Why are the Arabari forests of Bengal known to be a good example of conserved forest?

The forest department developed a strategy in which the villagers were involved in the protection of the forest. In return for the labour, the villagers were paid and also had some benefit in harvesting operations. They were allowed to collect wood and fodder on payment of nominal fee. In this way, by the active and willing participation of the local people, the sal forests of Arabari were conserved.

Sustainable Management of Natural Resources Class 10 Notes

• Updated on  
• Aug 29, 2020

With the growing awareness towards sustainability especially in the context of environmental conservation , there is an increase in eco-friendly technologies and products which can be incorporated into our everyday lives to do our part towards saving the planet earth. Class 10 Science students are provided with a detailed chapter on Sustainable Management of Natural Resources to impart them with the knowledge of environmental management and sustainability. If you are searching for Sustainable Management of Natural Resource Class 10 notes for revision, you have surely come to the right blog! In this blog, we have summarized the chapter 16 of Class 10 Science and explored the key essentials of how sustainable management of natural resources can be ensured.

Natural Resources

The first concept you will get to learn in our Sustainable Management of Natural Resources Class 10 notes is the basic definition of natural resources. The resources that are present in the environment and contribute to the life and being of humankind are known as natural resources. There are two main types of natural resources:

Exhaustible Natural Resources : These resources can be exhausted if the rate of usage of the resource is greater than the rate of replenishment of the resource. 

Inexhaustible Natural Resources : These resources cannot be exhausted even if they are used repeatedly and continuously. 

Why Do We Need to Manage Our Natural Resources?

Natural resources form the foundational and basic elements of the things we use or consume, be it food, electricity, clothes, transportation, living spaces, amongst others. We need to use these natural resources carefully as they are limited and with reckless use, they will soon be scarce. Going through our Sustainable Management of Natural Resources Class 10 notes, you must understand how important and crucial it is to manage the reservoirs of our natural resources and utilize them in an optimal way. The sustainable management of natural resources is primarily a way to control natural resources’ use, especially exhaustible ones so that their usage is optimum, and their wastage is wholly avoided. 

Moving further, you must also familiarize yourself with the 3Rs which are essentially included in our Sustainable Management of Natural Resources Class 10 notes. The three Rs that can help people save the environment are Reduce, Reuse and Recycle.

• To reduce means to lessen the usage of such materials that can seriously harm the environment. If people stop using these materials, it will have a domino effect, and the production of such materials will also eventually reduce.
• To reuse means to collect and use harmful materials repeatedly so that they do not need to be bought again and again. This is bound to reduce the sale of such items and their production as well, which has great potential to save the environment.
• The third R is to recycle. This means that such materials that may potentially harm the environment must be recycled to the greatest extent possible. Recycling helps obtain base materials again.

Conservation of Forests and Wildlife

The conservation of wildlife is among the most important parts of the conservation of natural resources. While studying the Sustainable Management of Natural Resources Class 10 notes, you must know that the conservation of wildlife is not just important because it helps maintain the balance in the ecology of a particular region and the planet as a whole, but also because it helps preserve the gene pool. Wildlife not being conserved can lead to species going extinct.

The conservation of wildlife means:

• developing laws that protect the wildlife of an area
• incentivizing people to protect and preserve rare and endangered species
• conducting periodic surveys of areas of rich wildlife to understand its ecology, and take steps to preserve it
• imposing severe restrictions on deforestation

The conservation of forests can be done through sustainable management. The main steps for the conservation of forests are:

• afforestation (the planting of new trees of barren land)
• reforestation (the replanting of trees on the land that was earlier exploited)
• separation of commercial forestry
• the regulation of grazing

The chapter on Sustainable Management of Natural Resources in Class 10 also notes that forests primarily need to be conserved due to the vast and harmful effects of deforestation. The main effects of deforestation are soil erosion, desertification, floods, the destruction of wildlife, and changes in the climate of a region. 

Conservation of Water

All forms of life require water to sustain life. This makes water among the most important resources on the Earth. Not being able to retain water in a region can lead to the complete loss of life from that region. In regions where water is naturally not present, ways of irrigation such as dams may be built. Here are the major advantages and disadvantages you must remember while revising our Sustainable Management of Natural Resources Class 10 notes:

The advantages of dams include: 

• They can ensure a year-round supply of water for a region.
• The water from the dam can be treated and further supplied to people in nearby residential areas, where natural sources of water might not otherwise be present.
• The water of a dam is present at a great height, and hence may be used to generate electricity by harnessing the potential energy of water maintained at a height.

However, building dams also carries its own set of disadvantages:

• The construction of dams causes a large number of people to be dislocated from their homes, sometimes with very little compensation.
• The construction of dams also causes deforestation and disturbs the ecology of a region.

A better way of conserving water is through the harvesting of water. Different states of India have different ways in which water is harvested. The harvesting of water can also be combined with filtration systems so that clean water may be obtained. 

Conservation of Fossil Fuels

The next sub-unit in the chapter on Sustainable Management of Natural Resources in Class 10 explores the integral ways to facilitate the conservation of fossil fuels. The two primary fossil fuels are coal and petroleum. Coal has been derived from plant remains, while petroleum has been derived from liquefied plant and animal remains that have been pressurized over millions of years.

The conservation of fossil fuels can be done in a number of ways:

• The use of fossil fuels can be replaced with other fuels such as compressed natural gas.
• While these generally are derived from fossil fuels themselves, it is also prudent to note that they do not cause as much pollution as fossil fuels due and also last longer.
• The wastage of fossil fuels during their extraction must also be avoided at all costs.
• The overconsumption of fossil fuels in various industries must be checked and regulated. 
• Several alternative sources of energy can also be utilized instead of fossil fuels. 
• These sources include hydroelectric power, nuclear power, wind power, and solar power.

Hence, we hope that our Sustainable Management of Natural Resources Class 10 notes help you understand the major aspects covered in this chapter.

Question. What are the products formed when coal and petroleum are burnt? Answer :  Carbon dioxide, water, oxides of nitrogen and oxides of sulphur.

Short Answer Type Questions

Question. Why must we conserve our forests? List two factors responsible for causing deforestation. Answer: We must conserve our forests as they are useful resources. Forests are useful to us in many ways: (i) They provide living places (natural habitats), shelter, protection and food to our wildlife. (ii) They provide timber for making furniture, houses, boats and other useful things of daily use. (iii) They provide raw materials for paper, rayon and many other industries. (iv) They are the rich source of many other things like honey, lac, medicines, dyes, katha, sandalwood, spices etc. (v) They help in maintaining a balance of gases like CO2 and O2 in the atmosphere, etc. Two main reasons for deforestation are as follows: (i) Indiscriminate felling of trees for the purpose of timber, fuel and industrial demand of wood, building dams, etc. (ii) Over-grazing by a large livestock population.

Question. What is sustainable development? State its two main objectives. Answer: Sustainable development can be defined as management of available resources and development of new techniques for use of natural resources to meet the changing basic human needs, at the same time preserving the resources for the need of future generations. The two main objectives of sustainable development are: (i) To reduce the dependence on the conventional sources and adopt non-conventional sources of energy. (ii) Evolving new technology and conserving natural resources.

Question. (a) Why do we need to manage our resources carefully? (b) Why management of natural resources requires a long term perspective? Answer: (a) : The resources of Earth are limited and their demand is increasing day by day with ever growing population. So, we have to avoid their wastage and should properly manage, conserve and replenish our natural resources. (b) Management of natural resources requires a long term perspective so that they can last for generations to come and may not be merely exploited for short term gains.

Question. What is meant by ‘‘sustainable management’’? Why is reuse considered better than recycling? Answer: Sustainable management means managing the use of natural resources in a way that they fulfill the needs of present generation and are also conserved for future generations. Reuse is considered better than recycling because reusing products reduces the amount of waste and saves energy needed to recycle it.

Question. Everyone of us can do something to reduce our personal consumption of various natural resources. List four such activities based on 3-R approach. Answer: Activities which can reduce consumption of natural resources are as follows: (i) If we take public transport instead of private transport to travel to our destinations then we can help reduce the use of fossil fuels. (ii) Reusing the water used for washing vegetables, to water plants in the garden can help in saving water. (iii) Repairing and reusing old mobiles, televisions, etc., help reduce consumption of natural resources. (iv) Promoting the use of furniture made of metals, fabrics, etc., instead of wood can help reduce the cutting of trees for making such items.

Question. Why is sustainable management of natural resources necessary? Out of the two-reuse and recycle-which, in your opinion is better to practise? Give reason. Answer: Sustainable management of natural resources is necessary because : (i) The resources of the Earth are limited and because of the rapid increase in human population, the demand for resources is increasing day by day. Proper management can ensure that the natural resources are used judiciously so that they fulfil the needs of present generation and also last for the generations to come. (ii) It also takes into consideration long-term perspective and prevents exploitation of natural resources for short-term gains. The process of ‘reuse’ is better than that of ‘recycling’ because some energy is used to recycle old objects but no energy is required during reuse.

Question. Management of forest and wild life resources is a very challenging task. Why? Give any two reasons.  Answer: Management of the forest and wildlife resources is considered as a challenging task as there are many stakeholders of forest. These stakeholders are directly or indirectly involved in forest and wildlife resources. These stakeholders are : (i) The people who live in or around forests and are dependent on forest products for various aspects of their lives. (ii) The industrialists who use various forest products and the wildlife enthusiasts who want to conserve the forest and wildlife. (iii) The Forest Department of the Government which owns the land and controls the resources from forests. Maintaining the interest of all the stakeholders is a challenging task as (i) Due to industrialisation and urbanisation forest resources are depleting. (ii) There are profit makers who want to make money from this resource.

Question. What is meant by three types of ‘R’ (3-Rs) to save the environment? Explain with examples how would you follow the 3-Rs in your school to save the environment.  Answer: 3-Rs to save the environment are reduce, recycle and reuse. For sustainable use of resources, the three Rs can be practised in school in following ways : Reduce : Switching of unnecessary lights and fans when not in use, avoiding wastage of food, closing of over flowing taps. Recycle : Students should segregate the wastes generated in classroom and should discard them in separate dustbins for their proper disposal. Reuse : Certain items can be reused like old books should not be thrown instead can be given to junior students for their use.

Question. Write two advantages of sustainable management of natural resources. Out of the two – reuse and recycle – which is better and why?  Answer:  Two advantages of sustainable management of natural resources are : (i) It avoids wasteful use of natural resources and (ii) Benefits of the resources are conserved for present as well as future generations. Of the two, reuse and recycle, reuse is better because reusing an item helps to conserve energy that may be required to recycle it.

Question. What is meant by wildlife? How is it important for us?  Answer: Life in any form (plants or animals), which exists in its natural habitat is called wildlife. Wildlife is very important for us, as it provides ecological stability by maintaining the food chain. Wildlife is important to us in following ways: (i) Wildlife is a renewable source of large variety of commercial products like food, fur, lac, musk, leather, feather, ivory, timber, fibre, fodder, fuel, medicines, etc., which can be used from time to time. (ii) Wildlife is considered as gene bank, which can be used for producing high yielding plants and animals through the process of selection and hybridisation. (iii) The wildlife can be used commercially to earn money through tourism (jungle safari, etc.) as it provides best means of sports and recreation.

Question. State two advantages of conserving (i) forests, and (ii) wildlife.  Answer:  Two advantages of conserving forests and wildlife are : (i) Forests (a) Forests provide us a number of valuable goods i.e., wood, spices, rubber, etc. (b) Forests help to reduce atmospheric pollution. They absorb CO2, collect suspended particles and reduce noise. (ii) Wildlife (a) Wildlife helps to maintain ecological balance of nature. (b) Wild animals are a source of valuable products like ivory, honey, musk, etc.

Question. Explain giving example where active involvement of local people lead to effcient management of forest.  Answer: Active participation of public and their support must be generated in order to conserve our forests and wildlife to achieve the real goal of ecodevelopment. An example of public participation in conservation of forest and wildlife is the case of the Bishnoi Community in Rajasthan. In 1731, Amrita Devi Bishnoi sacrifficed her life along with 363 others for the protection of ‘Khejri’ trees in Khejrali village near Jodhpur in Rajasthan.

Question. ‘‘What was Chipko Andolan’’? How did this Andolan ultimately benefit the local people and the environment? Answer: The Chipko Andolan (tree hugging movement) is an example of the contribution of common people towards the conservation of forests. The Chipko Andolan originated from an incidence in a remote village of Garhwal, high up in the Himalayas in the early 1970s. A logging contractor had been allowed to cut down trees in a forest close to a village. The people of the village did not want this forest to be cleared because it would spoil their healthy environment. One day, when the men folk of the village were out for work, the contractor’s workers came in the forest to cut down the trees. In the absence of men, the women of the village reached the forest quickly and clasped the tree trunks with their arms, preventing the workers from cutting them down. The forest trees were thus saved. The Chipko movement quickly spread across all the communities and helped in the conservation of forests thereby contributing to the service of mankind. Both local people and environment were benefitted due to conservation of food, fooder, fuel fibre and fertiliser trees.

Question. Forests are ‘‘biodiversity hotspots’’. Justify this statement. Answer: Forests are reservoirs of diversity. They contain different species of plants, animals and all sorts of living organisms. Forests are also under severe threat due to habitat loss, climate change and extensive species loss. Hence, they are considered as biodiversity hotspots.

Question. List four causes of damage to forests. Answer: Four causes of damage to forests are: (i) Increasing human population necessitates the expansion of human habilitation which requires clearing of forests to make more land available for residential purposes. (ii) Rapid industrialisation also mandates setting up of new factories. Land for factory set up is also made available by clearing forests. (iii) Ever increasing human population increases the demand of fresh supply of wooden furniture and other items for which trees are cut. (iv) Forest fres resulting from mishandling of inflammable objects, left unattended campfire, negligently discarded cigarettes etc., by humans causes damage to forests on a large scale.

Question. How do advantages of exploiting natural resources with short term gains in mind differ from the advantages of managing our resources with a long-term perspective? Answer:  The advantages of exploiting resources with short term aim is to meet the immediate basic human needs. Short term exploitation of natural resources meets the current demand. It is beneficial for the present generation only whereas management of resources with long term perspective is aimed to fulffil the needs of future generations. Long term use of resources can be achieved through their sustainable use.

Question. What is biodiversity? What will happen if biodiversity of an area is not preserved? Answer: Biodiversity refers to the variety and variability of living organisms on Earth or in a particular habitat. Biodiversity forms the foundation of the vast array of ecosystem services (pollination, food, timber, spices, etc.) that critically contribute to human well being. Biodiversity boosts ecosystem productivity where each species, no matter how small, has an important role to play. Hence, biodiversity is required for maintaining ecological balance. Loss of biodiversity will disturb ecological balance and create an ecological imbalance. Moreover it will deprive humans of some important ecological services.

Question. List two criteria of measuring the biodiversity of an area.  Answer: The basic criteria of measuring the biodiversity of an area are: (i) The presence of varied number of organisms and the type of ecosystem present in the area. (ii) Indicator organisms are also a measure of biodiversity.

Question. Monoculture of a particular type of tree is no substitute for natural forests. List two reasons to justify this statement.  Answer: Monoculture of few plants is useful for few industries. It is a source of earning for the forest department only but leads to loss of biodiversity and also varied needs of villagers and local people cannot be met. Hence, it cannot be a substitute of natural forest.

Question. What is ‘Chipko movement”? Why should we conserve forests? Answer: Chipko movement was started by women to stop the felling of forest trees of their area. These women literally clasped the tree trunks to prevent the workers of the contractor to cut the trees. It was started in early 1970s in village Reni in Garhwal district of Uttarakhand. Forests are important renewable natural resources dominated mainly by trees. They are essential for ecological balance of all ecosystems. They maintain biological diversity, regulate water cycle, prevent soil erosion and foods, recharge water table, etc. We obtain many useful products like wood, food, drugs etc., from forests. Thus, conservation of forests is utmost important.

Question. Water is a valuable resource. List two ways that you would suggest every family member to save this resource.  Answer: Water is a valuable resource and to save this resource two suggestive methods are : (i) Preventing wastage of water, in household by turning of tap when not in use while brushing, shaving, etc., and in public places. (ii) Promoting reusing water like water, used for washing vegetables can be reused for watering garden plants.

Question. What is watershed management system? List two benefits derived by the communities that participate in this system. Answer: Watershed management emphasises scientiffic soil and water conservation in order to increase the biomass production. The aim is to develop primary resources of land and water so that they can be used to produce secondary resources of plants and animals without causing the ecological imbalance. Benefits derived from watershed management are: (i) It identifies degraded area of land and emphasises the need of the improvement of quality and quantity of clean water to the local community and thus ensures their participation. (ii) Construction of a series of long trenches and mounds to hold rain water and allow it to percolate into the ground, thus increasing the ground water.

Question. List two causes of pollution of river Ganga. Answer: The two causes of pollution of river Ganga are : (i) Increasing human activities like bathing, washing clothes, bathing of animals, in river water. (ii) Dumping of industrial wastes and ashes of corpses which are cremated in the water of river Ganga.

Question. Why do we need to use our resources carefully? Answer :  It is because these resources are limited and the human population is increasing at very fast rate, the demand for these resources is increasing. For long term usage and to preserve them we need to use our resources carefully.

Question. For the conservation of forest who can be a stakeholder. Answer :  (i) The people who live in or around forest. (ii) The forest department of the government. (iii) The industrialists. (iv) The wildlife and nature enthusiasts who want to conserve nature.

Question. List four changes you would incorporate in your life style in a move towards sustainable use of available resources  Answer :  (i) Taking a bus, using cycle or walking. (ii) Using CFL at home and switching off lights when not required. (iii) Using the stairs instead of lift. (iv) Wearing an extra sweater on cold days instead of encouraging the use of heaters.

Question. Prejudice against the traditional use of forest areas has no basis. Comment. Answer :  It can be explained with one example—The great Himalayan Park contain alpine meadows which were grazed by sheep in summer. Nomadic shepherds drove their flock up from the valley every summer. When the National Park was formed this practice was banned. Because of no grazing, the grass first grew very tall and then fell over on the ground preventing fresh growth. Hence the traditional use was helpful for the forest maintenance.

Question. Why is it necessary to conserve forest and wildlife? Answer :  To preserve forest, maintain balance in the eco-system, prevent floods, droughts.

Project On Management Of Natural Resources For Class 10

Table of Contents

INTRODUCTION :

Natural resources, such as the air we breathe, the water we drink, the land we live on, and the biodiversity that surrounds us, are the fundamental building elements of our world. The process of conserving and utilising natural resources in a way that is sustainable and advantageous to both current and future generations is referred to as management of natural resources. It is a crucial component of environmental management that contributes to maintaining the health and viability of our planet over the long term. We will go deeper into the idea of natural resource management and its different components in this project.

WHY ARE NATURAL RESOURCES NECESSARY?

For all living things to survive and develop, natural resources are necessary. Here are a few explanations for why we require natural resources:

Energy : To produce the energy that runs our homes, businesses, and industries , renewable energy sources like solar, wind, and hydroelectricity are combined with natural resources like coal, oil, and natural gas.

All life forms depend on water, which is utilised for drinking, irrigation, and other industrial processes.

Food: Agriculture, which provides the food that keeps us alive, depends on natural resources like rich soil, pure water, and sunlight.

Drugs: Plants and minerals are examples of natural resources that are used to make many of the medications that we use to treat ailments and diseases.

Materials for construction: Natural resources like wood, stone, and metal are used to construct buildings, roads, and other infrastructure.

In conclusion, natural resources are essential for meeting our basic requirements, such as those for food, water, shelter, and energy, and they also promote the advancement of economic and technical systems.

TYPES OF NATURAL RESOURCES

Based on where they came from, natural resources can be generally divided into three groups:

Resources that can be regenerated over time—either naturally or as a result of human activity—are referred to as renewable resources. Solar energy, wind energy, hydroelectricity, biomass, and geothermal energy are a few examples.

Resources that cannot be replaced after being used up are referred to as non-renewable resources. Examples include minerals like iron, copper, and gold as well as fossil fuels like coal, oil, and natural gas.

Resources that are unaffected by human use are known as inexhaustible resources. Examples include solar energy, wind energy, and tidal energy.

Natural resources can also be divided into smaller groups based on how they are used, such as energy resources, mineral resources, water resources, and forest resources.

WILDLIFE AND FOREST

Two essential natural resource components are forests and wildlife. Large tracts of land covered with trees and other plants are known as forests, and they have various ecological and economic advantages. By providing home for countless kinds of plants and animals, forests sustain biodiversity through regulating the climate, preserving soil fertility, preventing soil erosion, and all of the aforementioned.

Any living things that are not domesticated and are found in their natural environments are referred to be wildlife. Wildlife, which includes animals, birds, fish, and reptiles, is crucial for preserving the ecological equilibrium. Among other ecosystem functions, they aid in pollination, seed distribution, insect control, and nutrient cycling.

Yet, human activities like deforestation, overgrazing, poaching, and habitat destruction pose various dangers to forests and wildlife. To prevent future deterioration and extinction of forests and species, conservation activities are required. In addition to awareness campaigns, education initiatives, and sustainable forest management techniques, conservation measures include the establishment of national parks, wildlife reserves, and protected areas.

WATER FOR EVERYONE

For human health and survival, having access to clean water is crucial. Yet, access to clean water is a problem that affects billions of people worldwide, and it is made worse in poorer nations. To guarantee that everyone has access to clean and safe water, it is imperative to address the serious issues of water scarcity and water pollution.

When the demand for water outweighs the supply, water scarcity results. Many reasons, such as population growth, climate change, and ineffective water management policies, may be to blame for this. As water becomes contaminated with dangerous elements like chemicals, bacteria, and viruses, it becomes unfit to drink.

There are several actions that can be taken to alleviate these problems, such as:

encouraging the use of water-saving gadgets and techniques like drip irrigation and rainwater collection.

Purchasing water treatment equipment to raise the quality of the water.

constructing water infrastructure, such as pipelines, canals, and dams, to enhance the availability of water.

putting policies and rules into practise to stop water contamination and uphold standards for water quality.

educating localities on the value of water conservation and environmentally friendly water management techniques.

We can guarantee that everyone has access to clean, safe water—which is crucial for maintaining human health and wellbeing—by putting these steps into place.

Large constructions known as dams are placed across rivers and streams to regulate water flow and store water for a variety of uses. Dams are crucial for irrigation, flood control, hydroelectric power generation, and water storage. Yet dam building and maintenance also have a big impact on the environment and society.

Dams have a number of benefits, including:

Water storage: Dams are capable of holding vast volumes of water that can be used for agriculture, drinking, and industrial uses.

Hydroelectric power generation: By using turbines that are powered by falling water, dams may produce energy.

Flood control: By managing the water flow in rivers and streams, dams can aid in the prevention of floods.

Recreation: Activities like boating, fishing, and swimming can be done in reservoirs created by dams.

Yet dam building and operation also have substantial effects on the environment and society, such as:

Displacement of people: Building dams may force local communities out of their homes, which could have serious social and economic repercussions.

Loss of natural habitat: The construction of reservoirs may cause the loss of plant and animal habitats.

Water quality: By modifying water flow, temperature, and nutrient levels, dams can have an impact on water quality.

Greenhouse gas emissions: Carbon dioxide and methane greenhouse gases can be released during the degradation of plants in reservoirs.

There are a number of steps that may be taken to lessen the negative effects of dams, including as carrying out environmental impact assessments, involving local populations in the decision-making process, and putting policies in place to lessen the effects of dam construction and operation.

PETROLEUM AND COAL

Petroleum and coal are two non-renewable energy sources that are frequently utilised in industry, transportation, and power generation. Unfortunately, using coal and petroleum also has a lot of negative effects on the environment and human health.

A fossil fuel largely used for the production of power is coal. Climate change is exacerbated by the large greenhouse gas emissions from coal mining and burning. Significant environmental effects of coal mining include habitat damage, water pollution, and soil erosion.

Petroleum, usually referred to as oil, is a fossil fuel that is largely used in industry and transportation. Petroleum is also extracted and burned, which results in a considerable amount of greenhouse gas emissions and climate change. Offshore drilling and transportation oil spills have the potential to seriously harm marine ecosystems.

Many steps can be taken to lessen the harmful effects of using coal and petroleum, including:

encouraging energy efficiency and conservation to lower energy consumption.

developing and supporting renewable energy sources, such as hydropower, wind power, and solar power.

putting policies and rules into effect that will lower greenhouse gas emissions and encourage the use of cleaner energy.

promoting the use of electric vehicles, carpooling, and public transportation to cut down on the usage of petroleum.

encouraging environmentally friendly mining methods and minimising mining’s negative effects.

By putting these steps in place, we can lessen our reliance on coal and oil and shift to a cleaner, more sustainable energy future.

THE FIVE ‘R’ PRINCIPLES OF WASTE MANAGEMENT

The act of gathering, moving, processing, and disposing of trash in a way that is both environmentally and socially responsible is known as waste management . A helpful foundation for decreasing waste and supporting sustainable waste management practises is the “Five R” principle of waste management. There are five R’s:

Reduce: The word “reduce” is the first R. This entails utilising less material or packaging to reduce the quantity of waste produced.

Reuse: Reuse is denoted by the second R. This entails reusing goods and resources several times before discarding them.

Recycle The word “recycle” is the third R. To develop new items, recycling resources like paper, glass, and plastic is necessary.

Recover The word “recover” is the fourth R. This refers to extracting energy from waste through other processes, such as incineration.

Dispose : Dispose is denoted by the sixth R. This entails properly managing garbage in terms of both the environment and society.

We can limit the quantity of waste produced, save resources, and lessen the harmful effects of garbage on the environment and human health by adhering to the five R principle. The following actions can be conducted specifically to use the five R principle:

utilising reusable bottles, bags, and containers in lieu of single-use products.

Paper, glass, plastic, and other items can all be recycled.

composting organic waste, such as leftover food and yard debris.

Rather than throwing away unwanted stuff, consider donating or selling them.

removing hazardous waste items like batteries and electronics from the environment properly.

By using the five R waste management principle, we may encourage sustainable waste management methods and reduce trash, making our environment cleaner and healthier.

Finally, it should be noted that effective management of natural resources is essential for the survival of our planet and the welfare of all living things. Sustainable management of natural resources is crucial to maintain their availability for future generations because they are vital for human life and progress.

Natural resources are necessary for a variety of human needs, such as food, shelter, energy, and transportation. However the exploitation of natural resources has negative effects on the environment and society, such as habitat loss, water pollution, and climate change.

We must adopt methods for resource conservation, the promotion of renewable energy, the preservation of wildlife and forests, and waste reduction if we want to manage natural resources sustainably. A helpful foundation for decreasing waste and supporting sustainable waste management practises is the “Five R” principle of waste management.

In conclusion, governing bodies, local communities, and people all need to work together to manage natural resources sustainably. We can guarantee that natural resources are accessible to future generations while maintaining the integrity of our planet’s ecosystems by banding together and implementing sustainable practises.
