Human activity is the main cause of soil degradation. Agriculture plays a large part in soil degradation, especially clearing, irrigation, the spreading of chemical fertilizers and pesticides, overgrazing and even the passage of heavy farming equipment. Tillage and the clearing and deforestation of large plots of land also lead to soil degradation. Improper drainage in agricultural fields also contributes to soil degradation.
land degradation causes soil errosion which further lead to drought and desertification.
Sand mining is usually called sand quarrying in Britain. Sand quarrying is when a deposit on land of sand is viable and profitable to be extracted out of the ground - commercially viable is the main criteria! Mining implies going underground to follow a seam of coal, copper, and other materials. It is much cheaper to open-cast rather then go underground. Any quarried sand could be used in several ways, depending on the quality. This is why you may see sharp sand, silver sand, etc, advertised for sale or used in commercial manufacturing of certain products.

the main causes for the land degradation in the punjab is theintensive cultivation.
soolution mining can cause subsidence of land where the salt used to be. this could cause buildings to collapse and ground to be ruined
The principal cause of soil degradation along the Murray River is improper land use. Certain agricultural practices cause erosion, whilst over-iriigating causes increased salinity.
Primary sectors are classified as those which produce or obtain the raw materials or natural products from the land or sea for industry. Examples include Mining, Quarrying, Farming, Fishing, Forestry, Potter

Land pollution normally becomes a hazard or endangers the life of animals that live in the given area. Land pollution may also cause a degradation of vegetation and natural habitats.
Go to google images and type 'effects of land degradation' or just 'land degradation' and you should get what you want. You can also type in things like removal of topsoil & mudslides because they come under soil erosion and soil erosion. Soil erosion is a factor of land degradation. http://en.wikipedia.org/wiki/Land_degradation This website has effects of land degradation. You can also type a few of those effects in google images.
