Introduction to Classification of ResourcesAll objects found in the environment which can be used to satisfy human needs are termed as resources. It requires the provision of accessibility of technological development of the people, the commercial viability of exploiting the resource and the cultural acceptance of these resources.
Resources may be classified as follows :
Types of Resources
On the basis of origin, resources are categorised as follows:
- Biotic resources are obtained from the biospehere and comprises living organisms. The flora and fauna of a region are renewable resources.
- Abiotic resources consist of non-living objects. They are non-renewable in nature, but some of them can be recycled. Water, solar energy and wind energy are some of such resources.
On the basis of exhaustibility, resources are classified as follows:
- Renewable resources are those which have unlimited supply, can be renewed over a short period of time and cannot be exhausted. Water, wind and solar energy are some examples.
- Non-renewable resources are exhaustible resources and cannot be renewed. They are limited in availability and take a long period of time in the geological time-scale to get regenerated. Fossil fuels and minerals are some examples.
On the basis of ownership, resources are classified as follows:
- Individual resources are owned by individuals. The plots of land-owned privately by individuals, ponds, wells, etc., are examples.
- National resources belong to a nation. The forests, minerals, land within the nationâ€™s territory and territorial waters of a nation belong to this category.
- Community-owned resources are accessible to all members of the community. Parks, picnic spots, playgrounds, burial grounds, etc., are community-owned resources.
- International resources are regulated by international organizations. The oceanic resources situated beyond 200 km of Exclusive Economic Zone do not belong to any particular country and, hence, can be utilized only in accordance to international laws.
On the basis of availability and development, resources are classified as follows:
Potential resources: These are found in an area, but have not yet been utilised or developed. There is a huge potential for solar energy in Gujarat and Rajasthan, but this has not yet been optimally developed.
Developed resources: These are already surveyed with respect to their quantity and quality and are already in use. Technological development and accessibility of their location determine the quantity and quality of the developed resource.
Stock: It indicates those materials which has the potential to become a resource with proper technological development in future. Reserves are those materials which have not yet been utilised to their potential, although the technological advancements are available.
