Urban sprawl and soil sealing

An example of societal challenge related to land management

Urban sprawl leads to loss of agricultural land and thus to loss in food production capacity. Sealing leads to loss of water infiltration capacity exacerbating adverse climate change effects and diminishing the drinking water supply. The desire for bio energy requires extra green production which in turn consumes land and water and competes with the demands for food and water for drinking and industrial process. Loss of soil organic matter leads to desertification as well as excessive use of ground and surface water, which might influence nature (development) and other functions (drinking water) and require extra use of fertilizer and pesticides.
