RationaleThe demand for food and other agricultural products has been increasing tremendously in the recent past worldwide. This trend is likely to continue in future given the already high population growth rates in many countries and especially in Kenya. Concurrently, agricultural land is diminishing rapidly as demand for land increases due to urbanization and other infrastructure necessary for development. The resulting intensification in the utilization of the land resources has led to their deterioration. This problem has been aggravated by lack of highly trained manpower for effective utilization of land and other related resources. In addition, there is lack of appropriate agricultural power and machinery for sustainable agriculture.Consequently this Master‟s degree programmes are tailored to meet the demand for highly trained manpower in the following fields of specialization:i) Soil and Water Conservation Engineeringii) Farm Power and Machineryiii) Agricultural Structures and Processingiv) Environmental Engineeringv) Renewable Energy EngineeringIt is expected that the degree programmes shall provide highly trained manpower needed for analysis, design, and development of improved technologies for sustainable agricultural production.
