Sustainable Management of Natural Resources

Class 10 Science • Chapter 16

Chapter Overview

Natural resources such as forests, wildlife, water, coal, petroleum and minerals are essential for human life and economic development. These resources must be used carefully because many of them are limited and ecosystems can be damaged by unsustainable exploitation.

This chapter focuses on sustainable management of resources, stakeholder participation, forests and wildlife conservation, water harvesting, coal and petroleum, and the need to balance present needs with the needs of future generations.

Quick Revision

Sustainable development aims to meet present needs without compromising the ability of future generations to meet their needs.
Natural-resource management should consider environmental, economic and social factors.
Different stakeholders may depend on the same resource in different ways.
Forests support biodiversity, soil conservation, water cycles and human livelihoods.
The Chipko movement is an important example of community participation in forest conservation.
Large dams can provide irrigation, hydroelectricity and water storage, but may also cause ecological and social impacts.
Rainwater harvesting helps collect and conserve rainwater and can support groundwater recharge.
Coal and petroleum are finite fossil-fuel resources.
Using resources efficiently reduces pressure on natural systems.
The 3R principle stands for Reduce, Reuse and Recycle.

Major Stakeholders

Stakeholder	Interest / Role
Local Communities	Livelihoods, access to forests, water and other resources.
Industries	Use natural resources as raw materials and energy sources.
Government	Regulation, conservation, infrastructure and policy.
Environmental Groups	Protection of ecosystems, biodiversity and environmental quality.

Water Conservation

Water is a critical natural resource. Sustainable water management includes reducing wastage, protecting water sources, improving efficiency and collecting rainwater.

Important: Rainwater harvesting can reduce dependence on external water supplies and may help recharge groundwater where local conditions permit.

Advantages and Concerns of Large Dams

Advantages	Concerns
Irrigation	Displacement of people
Water storage	Submergence of land
Hydroelectric power	Changes in river ecosystems
Flood regulation in some systems	Impacts on downstream flows and habitats

Useful Relations for Practice

Percentage = Part / Whole × 100

Percentage Saving = (Original - New) / Original × 100

Water Collected = Area × Rainfall

For simplified rainfall-collection calculations, use consistent units.
