Trade off Analysis: An operational and accepted tool for policy analysis workshop, Intercontinental Hotel, Nairobi June 20-21, 2005
Main issues: population pressure, Land degradation due to steep slopes, persist drought, low farm incomes, low farm productivity, low Nitrogen and Phosphorous levels.
- Land controlled by clans, tribes or families
- Market economy
-Increased population: livestock and human leading to land degradation
(a) Pasture improvement, soil and water conservation, livestock water development, tsetse fly eradication.
(b) Modification of agro pastoralists perceptions and actions: grazing controls, ranching schemes, land tenure privatization.
(c) Improvement of livestock systems through breeding, disease control and marketing (ranches)
1970s to date: Disaster mitigation:
- Involves all stakeholders (move from top down heavy
capital intensive to smaller less capital intensive).
- Soil and water conservation
- Agro forestry
- Crop and livestock improvement
