Water situation is often very poor in Lawra area during the dry season. Big dams are not recommended to solve the problem because they may accelerate the erosion and cause healthy risks. Building of small-scale well in thus more preferable. The use of chemical pesticides increases the vulnerability of the soil to erosion, is expensive and harmful for the health, kills also useful species and promotes the development of pesticide resistant insects and weeds. Thus mechanical weeding and utilisation of local herbs, tree ash and neem powder is more profitable in the long run.
Erosion is loss of soil caused by rain and wind.
Erosion is a natural process - the problem is that human related activities such as intensive cultivation, deforestation, bush fires and grazing accelerate the rate of land degradation and erosion. Arid and sub-arid areas as well as slopes are most vulnerable for erosion and the process may lead to severe desertification unless soil conservation is practised. Rainsplash erosion 2.
