Water retention landscape: Mini catchment approach
conference contributionposted on 16.11.2018, 11:34 by George Wambugu
In arid and semi-arid lands (ASALs) in Kenya, where rainfall is low with scarce fodder for animals, vegetal cover and shooting trees are destroyed early by grazing animals leaving the soil bare and susceptible to soil erosion resulting in deep and wide gullies. The situation is exacerbated by human activities (charcoal burning, animal and human tracks/roads etc.). The ASALs make up over 80% of the country. Gulley head treatment is a simple low cost and effective method of stopping gulley advancement. It can be managed by the technical capacities of the local communities with basic financial support in capacity building. Construction of some water and soil retaining structures may be required as well. This paper looks at efforts of a Community in Kitui, an ASAL area to de-silt their earth dam and mitigate its future rapid silting with gulley head treatment and intensive soil and water conservation through a mini catchment approach.
