They transform material available in our environment into resources and use them. These resources can be classified in the following ways – (a) On the basis of origin – biotic and abiotic (b) On the basis of exhaustibility – renewable and non-renewable (c) On the basis of ownership – individual, community, national and international Fig. 1.1: Interdependent relationship between (d) On the basis of status of development – nature, technology and institutions potential, developed stock and reserves.

Sustainable economic development means ‘development should take place without damaging the environment, and development DEVELOPMENT OF RESOURCES in the present should not compromise with the needs of the future generations.’ Resources are vital for human survival as well as for maintaining the quality of life. It was believed that resources are free gifts of nature. As a result, human beings used them indiscriminately and this has led to the Rio de Janeiro Earth Summit, 1992 following major problems.

In the states of Punjab, Haryana, western Uttar Substratum Pradesh, over irrigation is responsible for land weathered parent degradation due to water logging leading to rock material increase in salinity and alkalinity in the soil. The mineral processing like grinding of limestone for cement industry and calcite and soapstone for ceramic industry generate huge quantity of dust in the atmosphere.

In recent parent bed rock years, industrial effluents as waste have become a major source of land and water pollution in many parts of the country.

Black Soil Alluvial Soils These soils are black in colour and are also This is the most widely spread and important known as regur soils. Black soil is ideal for soil. In fact, the entire northern plains are growing cotton and is also known as black made of alluvial soil. These have been cotton soil.

As we move inlands towards the river valleys, soil particles appear some what bigger in size. In the upper reaches of the river valley i.e. near the place of the break of slope, the soils are coarse. Such soils are more common in piedmont plains such as Duars, Chos and Terai.
