More attention to the soil can boost food production

ScienceDaily (November 20, 2012)

According to FAO, in the last thirty years a quarter of all agricultural land has become less fertile as a result of erosion, silting, soil exhaustion or other forms of land degradation. If these problems were addressed in northern China, food production there could be boosted by 25 per cent.

Land degradation is a problem in the arid parts of the tropical and subtropical countries, which are home to over one and a half billion people. Erosion, caused by water and wind, and soil exhaustion are responsible for severe losses.

In a catchment area in China, Chinese and Dutch researchers have assessed that the food production could be at least 25 percent higher if erosion and salinization were mitigated by the introduction of conservation practices such as dams, terracing, mulching or agroforestry.
