Causes of Land Degradation Large scale soil erosion caused by running water and wind. Dumping of waste materials from mining centers and industrial units.

Over irrigatio n leads to an increase in salinity and alkalinity in the soil. Overgrazing by animals and deforestation by man. Wastewater from the industrial units pollutes the lands. Mineral processing like grinding of limestone for the cement industry and calcite and soap stone for ceramic industry creates a lot of dust.

This dust is deposited in the neighboring land Conservation of Land Soil erosion can be prevented by ending deforestation, controlling grazing, encouraging afforestation and practicing terrace farming in hilly areas. Preparation of shelter belts of plants and stabilizing of sand dunes by growing thorny bushes will help to prevent land degradation in deserts.

On the basis of exhaustibly : Renewable resources- These are those which get renewed or replenished quickly. Some of these are unlimited and are not affected by human activities. Example solar and wind energy. Yet careless use of certain renewable resources like water, soil and forest can affect their stock. Shortage and drying up of natural water sources is a major problem in many parts of the world today. Non-renewable- Non-renewable resources are those which have a limited stock. Once the stocks are exhausted it may take thousands of years to be renewed or replenished.

Example: Coal, petroleum and natural gas are some examples On The Basis of Development Actual resources- Actual resources are those resources whose quantity is known. These resources are being used in the present. The rich deposits of coal in Ruhr region of Germany and petroleum in the West Asia, the dark soils of the Deccan plateau in Maharashtra are all actual resources.

Potential resources- Potential resources are those whose entire quantity may not be known and these are not being used at present. These resources could be used in the future. The uranium found in Ladakh is an example of potential resource that could be used in the future.
