Classification of resources

Resources can be classified on different bases

On the basis of Origin

1 Biotic Resources – All living organisms in our environment are called biotic resources. For example, trees, animals, insects, etc.

2 Abiotic Resources – All non-living things present in our environment are termed as abiotic resources. For example – earth, air, water, metals, rocks, etc.

 On the basis of Exhaustibility :

  • 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.

 On the Basis of ownership:

  • 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.

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 technology 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.

What is Sustainable Development ?

The Development which takes place without damaging the environment and compromising with needs of future is called sustainable development.

Resource Planning

Resource planning refers to the strategy for planned and judicious utilisation of resources. Resource planning is essential for sustainable existence of all forms of life.

 

Land as Resource

We fulfill most of our needs from land, such as food, clothing, shelter, drinking water, etc. But in past few decades the quality of land is degrading fiercely because of human activity.

 

Soil

Soil supports the growth of plants. Soil is the natural home of many living organism, such as ants, rats, snakes, and many insects. Soil has 4 layers as shown below –

Soil is formed by the weathering process of the rocks. Various natural forces, such as temperature, running water, wind, etc. along with many physical and chemical changes are equally important in the formation of soil formation.

Classification of Soil

Alluvial Soil

 

Black Soil

Red  Soil

Laterite Soil

Arid Soil

Forest Soil

The forest soil is found in hilly areas. The soil in upper parts is highly acidic because of denudation. The soil in the lower part is highly fertile.

Mountain Soil

Soil Erosion and Soil Conservation

Removal of top soil is called soil erosion. Intense farming, grazing, construction activities and other human activities; along with deforestation have led to soil erosion. Soil erosion; if not checked in time; can even lead to desertification.

Soil conservation is important to prevent soil erosion. Soil conservation can be done by many methods. Afforestation is the main method because trees hold the topsoil in place. Terrace farming and shelter belt planting also help in soil conservation.
