Step-by-step explanation:
Types of Natural Resources: On the basis of abundance and availability, the natural resources are of two types
Inexhaustible.
Exhaustible.
(a) Inexhaustible: These are in plenty and cannot be exhausted by man’s consumption. For example; air, sand, clay etc. It gets affected by the over-population of mankind.
(b) Exhaustible: These are limited and can get exhausted over a period of time, i.e., coal, petroleum etc.
Management of Natural Resources: A system of controlling the use of natural resources in such a way, as to avoid their wastage and to use them in the most effective way is called management of natural resources.
Why do we Need to Manage Our Natural Resources: We need to manage our natural resources because of the following reasons :
The resources of the earth are limited. Because of the rapid increase in human population,
the demand for resources is increasing day-by-day. The proper management can ensure that the natural resources are used judiciously, so that they fulfill the needs of present generation and also last for the generations to come. –
The proper management of natural resources takes into consideration long-term perspective (or view) and prevents their exploitation to hilt for short-term gains.
The proper management can ensure equitable distribution of natural resources so that all the people can benefit from the development of these resources.
The proper management will take into consideration the damage caused to the environment during the ‘extraction’ or ‘use’ of the natural resources and find ways and means to minimise this damage.
Conservation of Wildlife: It is very important to conserve wild-life to maintain the ecological balance in nature and to preserve the gene pool. Some of the measures (or steps) to be taken for the conservation of wildlife are given below:
Laws should be made to impose a total ban on the poaching (killing) or capturing of any animal or bird belonging to an endangered species.
The natural habitats of wild animals and birds should be preserved by establishing National Parks and Sanctuaries throughout the country.
The Government Department connected with the conservation of wildlife should conduct a periodic survey in all the forests, National parks and Sanctuaries to have knowledge of the population of all species of wild animals and birds.
Special attention should be paid to the conservation of endangered species of wild animals and birds to prevent their extinction altogether.
The unauthorized felling (cutting) of forest trees for timber trade and fuel-wood should be curbed (stopped) immediately.
Forest and wild life conservation: Forests are biodiversity hot spots. Biodiversity of an area is the number of species of different life forms like bacteria, fungi, powering plants insects, birds, etc.
Hotspot means an area full of biological diversity.
loss of diversity may lead to a loss of ecological stability/ecological imbalance.
Stake holders: A person having interest or concern for something is called as a stakeholder.

Sustainable Management: Management of forest resources wisely to make it available for future generations.
To consider the conservation of forests, we need to look at the stakeholders who are :
The people who live in or around forests are dependent on forest products for various aspects of their life.
The Forest Department of the Government which owns the land and controls the resources from forests.
The industrialists—from those who use ‘tendu’ leaves to make bidis to the ones with papermills who use various forest produce.
The wild life and nature enthusiasts who want to conserve nature in its pristine form.
A major program called silviculture has been started to replenish the forests by growing more trees and plants.
Conservation of forests: It is carried out by the following methods
Afforestation: It is growing of forests on unprotected barren lands. Van Mahotsava is a tree plantation movement carried out twice a year (February and July) by both government and voluntary agencies.
Reforestation: It is developing forest cover in the area which has been damaged or cleared during exploitation.
Separation of Commercial Forestry: Useful plants required by industry should be planted separately preferably on waste land. Growing industry required plants is called production plantation.
Grazing: Grazing should be regulated according to the availability of pasturage.
Deforestation: Removal, decreases or deterioration of forest cover of an area is called deforestation.
