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. 


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. 


  • 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. 

Ch 16 Science Class 10 Notes: Importance of Management of Natural Resource

The Importance of the Management of Natural resources is as follows: 

  • 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.
