No
2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
Closed area management is an area within a watershed into which human and livestock access is limited, and the area is left for natural recovery of vegetation and soil. Management relates to activities by the community to ensure such protection and to support regeneration, such as constructing drainage and retention structures, selective bush removal, regular grass cutting, occasional tree planting, and organisation of economic activities like grass cutting.
2.2 Detailed description of the Technology
Description:
1. The closed area management technology is applied within Abagerima Learning Watershed of the Water and Land Resource Centre project.
2. In the area closures, community-based participatory management is applied to recover degraded areas.
3. The area is closed from agricultural activities and livestock grazing, while water harvesting and drainage structures are constructed, like small trenches and cut-off drains.
4. Natural grasses are regularly cut and carried, and selective trees are planted.
5. Forage growth for animal feed is encouraged, thereby reducing soil erosion, storing water, reducing soil loss, and avoiding conflicts with down-stream users.
6. The community is committed and responsible for closed area management, such as construction of trenches for water drainage and harvesting, plantation of trees, and to reduce soil erosion. The communities of the Abagerima Learning Watershed are very happy to manage their closed areas and equally share the grass biomass, and later on selective trees.
7. As a consequence, forage biomass has been increasing over the past 6 years and is regularly cut and carried, while indigenous and introduced trees are growing.
8. Through these activities, heavily degraded and overgrazed land could be transformed into productive land.
