1) Fanyajuu terrace is a type of soil and water conservation structure commonly found in the Sahel region of Africa. It is constructed by excavating a trench along the contour of the land and using the soil to create a raised embankment on the downhill side. This helps to trap and retain water, preventing soil erosion and improving agricultural productivity.
2) A soil bund is a simple earth embankment constructed to control erosion and manage water flow on agricultural land. It is built by excavating a trench along the contour of the land and using the soil to create a raised bund or embankment. This structure helps to slow down water runoff, trap sediment, and reduce soil erosion.
3) A stone-faced soil bund is a variation of a soil bund where stones are placed on the face of the embankment to increase its strength and durability. This can help to prevent erosion and improve water retention on agricultural land.
4) A trench is a long, narrow excavation in the ground used for various purposes such as drainage, irrigation, or as a foundation for structures. An eyebrow basin, on the other hand, is a small, shallow depression constructed at the base of a slope to collect and store water for agricultural use.
5) The function and advantage of all the above-mentioned structures include preventing soil erosion, improving water retention, and promoting sustainable agriculture practices. These structures help to conserve soil and water resources, increase agricultural productivity, and mitigate the impacts of drought and climate change. In conclusion, soil and water conservation structures such as fanyajuu terraces, soil bunds, stone-faced soil bunds, trenches, and eyebrow basins play a crucial role in sustainable land management and improving food security in arid and semi-arid regions. By implementing these structures, farmers can enhance their resilience to environmental challenges and ensure the long-term productivity of their land.
