Resource: Anything which can be used for satisfying the human needs is called a resource.
Resources can be classified on different bases; into following types:
On the basis of origin Biotic and Abiotic:-
On the basis of exhaustibility Renewable and Non-renewable
On the basis of ownership Individual, community, national and international
On the basis of status of development Potential, Developed, Stock and Reserves
Biotic Resources All living organisms in our environment are called biotic resources. For example, trees, animals, insects, etc.
Abiotic Resources All non-living things present in our environment are termed as abiotic resources. For example earth, air, water, metals, rocks, etc.
Renewable Resources: Resources that can be replenished after a short period of time are called Renewable Resources. For example agricultural crops, water, forest, wildlife, etc.
Non-renewable Resources Resources which takes million years of time to replenish are called non-renewable resources. For example fossil fuel.
Individual Resources owned by individuals are called Individual Resources. For example land owned by farmers, house, etc.
Community Resources owned by community or society are called Community Owned Resources. For example Graveyard, grazing land, ponds, burial grounds, park, etc.
National Resources Resources owned by Individual Nations are called National Resources. For example Government land, Roads, canals, railway, etc.
International Resources Resources regulate by International bodies are called International Resources. For example Ocean and sea beyond 200 km of the Exclusive Economic Zone and is called open sea or ocean. No individual country can utilize these resources without the permission of International bodies.
Classification of Resources - On the basis of Status of Development:
Potential Resources: Resources which are found in a particular region, but not yet used properly. For example Rajasthan and Gujarat receive plenty of solar energy and have plenty of wind energy, but use of these resources so far has not been developed properly.
Developed Resources: Resources which are developed and surveyed for utilization and are being used in present time are known as Developed Resources.
Stock Resources that are available, but we do not have proper technology to used them are called Stock. For example water is made of oxygen and hydrogen, which can be used as fuel, but because of lack of proper technology these are not being used.
Reserves Resources which are available and the knowhow to use them is also present but they are yet to be used are called Reserves. For example river water which is not used to generate electricity.
Resources are vital for human beings. But indiscriminate use of resources is creating many problems.
Accumulation of resources in only few hands leaves others unsatisfied.
Indiscriminate use of resources is creating many problems around the world, such as global warming, ecological crisis, disturbance in ozone layer, etc.
Thus, equal distribution of resources becomes necessary for sustainable development.
Sustainable Development: Development which takes place without damaging the environment and compromising with needs of future is called sustainable development.
Keeping the view of justified use of resources and sustainable development, the Earth Summit was organized in 1992 in Rio de Janeiro in which more than 100 state heads agreed with Agenda 21 for the sustainable development and proper use of resources.
Agenda 21 is an agenda to combat environmental damage, poverty, disease, etc. through global co-operation on common interests, mutual needs and shared responsibilities.
