desertification‚ decreases in agricultural productivity due to land degradation‚ sedimentation of waterways‚ and ecological collapse due to loss of the nutrient rich upper soil layers. Wind and water erosion are now the two primary causes of land degradation. The most effective known method for erosion prevention is to increase vegetative cover on the land‚ which helps prevent both wind and water erosion.

Nonpoint source pollution is land runoff from drainage‚ rain‚ and seepage and hydraulic modification. It is caused by rain or snow melt that moves through and over the ground. When the runoff moves‚ it collects and picks up manmade and natural pollutants and ends up spilling into lakes‚ rivers‚ streams‚ and coastal waters. Nonpoint source pollution can include things like motor oil‚ toxic chemicals‚ animal droppings‚ trash and even insecticides. Our drinking water needs to be protected. It takes

Soil conservation includes all such measures which protect the soil from erosion and restore its fertility. These measures are of two types-(a) small measures to check soil erosion at local or even individual level‚ and (b) large measures at government level involving larger area and heavy investment. (a) Small Measures-These include afforestation‚ regularised land strip cultivation or contour farming or terrace farming in hilly areas‚ use of stubble mulch system‚ increasing cohesiveness of the

basis. Watersheds have an infinite variety of shapes‚ and the shape supposedly reflects the way that runoff will “bunch up” at the outlet. A circular watershed would result in runoff from various parts of the watershed reaching the outlet at the same time. An elliptical watershed having the outlet at one end of the major axis and having the same area as the circular watershed would cause the runoff to be spread out over time‚ thus producing a smaller flood peak than that of the circular watershed

Bottom sediment may be stirred up by such actions as waves or currents‚ bottom-feeding fish‚ people swimming‚ or wading‚ or storm runoff. Clear water may appear cleaner than turbid water‚ but it is not necessarily healthier. Water may be clear because it has too little dissolved oxygen‚ too much acidity or too many contaminants to support aquatic life. Water that is turbid from plankton

The agricultural revolution refers to the important changes that took place in agriculture changes in the 18th century England CHANGES 1. Enclosure movements : Reasons: Growing population (need more food) Numbers of war fought with france Farmers wanting to have one or two large blocks of land instead of few scattered strip Methods: Landlord tried to set up large estates where they could use new farming methods and machines Forced the tenant farmers to give up their land‚ exchange land
