1. Deforestation in states like M.P. & Orissa. 2. Overgrazing in the states of Punjab & Haryana have cause land-degradation.3. Mining & quarrying have contributed a lot in land degradation as mining sites are abundant after excavation work is complete leaving deep scars. 4. Over irrigation in areas such as Punjab & Haryana also leads to land degradation due to water logging leading to increase in salinity & alkalinity in soil.5. Mineral processing like grinding of lime stone for cement industry generates huge quantity of dust in atmosphere after this dust settles down on land which stops percolation of water in soil. 6. Industrial effluents as wastes are a major source of land & water pollution.
