Resources:-
Everything available in our environment that has human value and is capable of satisfying our needs is called a resource.
It should be technically accessible, economically feasible, and culturally acceptable.
Physical Environment: Nature provides resources as assets to us.
Technology Knowledge: Suitable to specific conditions of a region to manage resources.
Institutions: Man gained knowledge, developed skills through experience, and learnt by practically working on something.
Depletion of resources for satisfying the greed of individuals.
Accumulating resources in a few hands divides society into rich and poor.
It has led to a global-ecological crisis or imbalance. Examples: Global Warming, Ozone layer depletion & environmental pollution.
Economical development should take place without damaging the environment.
Needs of future generations should be kept in mind.
It means a development in the present should not compromise with the needs of future generations.
For sustainable and economic development.
For reducing the gap between rich and poor.
For reducing the diversity of people with the help of technology and institutions.
Examples:
In the states of Jharkhand, Chhattisgarh and Madhya Pradesh are rich in Mineral and Coal resources.
Arunachal Pradesh has abundant water resources but lacks infrastructural development.
The state of Rajasthan is very well-endowed with solar and wind energy but lacks in water resources.
The cold desert of Ladakh is isolated from the rest of the country but has a very rich cultural heritage but is deficient in water.
The preparation of inventory resources.
Evolving the planning structure.
Matching the resource development.
Achieving the goal of development.
Availability of resources.
Technology.
Quality of Human Resources.
Historical experience of people.
Resources are important for developmental activities.
Overuse of resources and irrational consumption leads to socioeconomic and environmental problems.
To overcome these problems, the conservation of resources is necessary.
It supports human life.
Natural Vegetation & Wildlife.
Economic activities like Agriculture and Industry.
Transport and Communication.
It is also used for other purposes with careful planning.
Plains - 43%, Mountains - 30%, and Plateaus - 27%.
Land is a finite resource, it covers only 29% of the Earth's surface.
About 90% of humans live in 5% of the World's land.

Bad Methods of Farming
Deforestation
Overgrazing
Aforestation
Ploughing along the contour lines
Decelerate the flow of water down from the slopes
Terrace cultivation restricts erosion
Large fields can be divided into strips of grass left to grow between the crops
Planting lines of trees to create shelter and also works similarly
Rows of such trees are called shelter belts
Stabilization of sand-dunes in stabilizing the desert in Western India
Explain the land use patterns in India. And, why has land under forest not increased since 1960-61?
Answer:The land resources in India are primarily divided into
Agricultural Lands
Forest Land, where trees grow
Pastures and grazing land
Waste Lands
Rock and Desert areas and other non-agricultural areas.
The land under forest has not increased much since 1960-61 because of
indiscriminate cutting
felling of trees to make way for agriculture to feed our growing population
Intensive Urbanisation & Industrialisation
Large scale multi-purpose projects have submerged forests and trees.
Explain the land use patterns in India. And, why has land under forest not increased since 1960-61?
Answer:Technical and economic development involves more utilization and exploitation of resources for the present development.
Technical development and industrialisation need more resources for goods to be produced quickly & easily.
As means of transportation and communication are developing fast, they help in the mobility of resources.
Due to technological advancements, techniques of mining and quarrying are also improving leading to more and more resources for economic development.
Green Revolution led to the introduction of the latest mechanical devices, leading to more production and consumption of resources.
