Access Class 10 Science Chapter 16 – Management of Natural Resources

Why do we need to manage our resources?

• We should manage the resources as they are present in limited quantities and take millions of years to renew. 
• With the increase in the human population, there is a constant reduction in resources. 
• The management of the resources should be in a sustainable manner to protect the environment. 

Forest and Wildlife:

• Forests are known as the lungs of the Earth as they provide oxygen to the human population. 
• We depend upon the forests directly or indirectly for survival. 
• They also provide watershed protection, prevent erosion of soil and reduce climate change. 

Stakeholders:

The people who depend upon the forests for various life activities are known as stakeholders. These include: 

• Wildlife and nature enthusiasts
• Industrialists
• Forest department of the country

Sustainable Development:

The idea of using natural resources in the present without compromising the requirements of future generations is known as sustainable development. 

Water for All:

• Water is a basic necessity of life. 
• It is required for daily consumption by all living organisms. 
• The lack of water can cause serious health issues. 
• Humans are unable to sustain water resources due to a lack of the required resources and factors such as pollution. 

Dams:

• The structure which is used to control the flow of water in canals and rivers is known as a dam. It is used to convert the kinetic energy of water to electrical energy with the help of motors. 
• It helps in the storage of water. 
• It can prevent floods and drought-like situations. 
• Dams have caused harm to marine and human life.

Water Harvesting:

• The process of cleaning rainwater and using it for daily activities is known as water harvesting. 
• It is used in many states of India. 
• It can benefit irrigation, natural wells, etc. 
• Groundwater has advantages as it does not evaporate and does not provide breeding grounds. 

Coal and Petroleum:

• Coal and petroleum are millions of years old fossil fuels. 
• These resources can be exhausted in the future so we should sustainably use them. 
• Combustion of fossil fuels can produce carbon dioxide, water oxides of nitrogen, etc. 
• Carbon dioxide is a greenhouse gas, and its large volumes present in the air may lead to global warming. 

An Overview of Natural Resource Management:

• Natural resources are not available in large quantities so we should use them in a sustainable manner. 
• It can be a difficult task but we should try to achieve it properly. 
• We can protect our resources for future generations if they use them for sustainability.

• To avoid overindulgence in natural resources
• To help avoid more destruction of the world around us
• To support balance in our ecosystem.

The 3Rs of the Environment

The three Rs of the environment are as follows: 

• Reduce: The best way is to reduce waste production. 
• Reuse: One can limit environmental degradation by reusing products.
• Recycle:  It includes remanufacturing the used materials and selling the product in a new manner. 

Class 10 Ch 16 Science Notes: Stakeholders of the Forest and Their Role

• People who live in and around the forest depend upon it for food, medicines, fuel, fodder for cattle, etc. 
• The forest department and government use the forest for generating revenue by selling timber. 
• Industrialists depend upon forest resources for the production of raw materials.
