Hello, Greeting from the Forum for Sustainable Agriculture in Africa. Hope this finds well. One of FOSAA’s strategic objectives is to develop and strengthen collaborative research and mentorship centers and capacities for enhanced economies of scope and scale. In this regard, FOSAA has developed a seven years research/development project proposal entitled “Arresting desertification in Migera through soil health restoration”
Assessment of land quality is an effective method of evaluating sustainability of land use and management activities (De la Rosa, 2004, Food and Agriculture Organisation of the United Nations, 1983). This means that land productivity is highly dependent on land quality which is undermined by effects of overgrazing and nutrient mining. These include soil erosion, loss of organic matter, reduction of biodiversity and abundance for both fauna and flora and consequently land degradation. For example in Migera Sub-County lies a six square mile grazingland which in the early 1980s; was in good condition and comfortably supported approximately 1000 heads of cattle. In the early 1990s, patches of bare soils began appearing at various points of the farm. According to the owners, they believe the cause of this was prolonged droughts experienced in the area and large population of termites which eat up the vegetation roots leading to its desiccation. In response, they relocated their herd to elsewhere and forbid others from grazing on the land. To their dismay, the situation did not revert. Termite damage to vegetation is more pronounced during water stress conditions. As of 2011, approximately three square miles of this land is completely bare with no vegetation cover. Based on observation using a stone marked by the owners in 1996, approximately 50 cm of top soil has been lost due to wind and water erosion. Continued erosion reduces the land elevation of an area rendering it susceptible to flooding (Islam et al., 2008). Although bare soils still appear in patches, there is a possibility that the entire area can turn bare if no interventions are considered to arrest the situation. This could also be a genesis of another dissert. To make matters worse, as result of frustration, the owners of the land have opened up the land to charcoal burners depleting the remaining vegetation on the land.
Your contribution (financial or in kind) in this regard will be highly appreciated.
