Abstract:This paper assesses the potential for water harvesting technologies (WHT) in farming systems affected by drought or water scarcity. A major assumption of the paper is that the earth's water supplies do not preclude water shortages, particularly in situations where water management principles, procedures and tools are in deficit. The analysis is based on data collected from the Manadara Mountains Region of northern Cameroon in 1998, using a combination of research methods: personal interviews, field observations, and document analysis. The objectives of the study were to ascertain the economic potential of WHTs in the region, with a view to their promotion; enhance a better understanding of the potential and scope of WHTs for their replication in other regions; and increase knowledge on WHTs so as to improve the methods required for their adoption and diffusion. The findings indicate that six WHTs are used in the area: flood diversion, mini dams, watering ponds, micro/sand dams, rooftop, and rock-based water harvesting. The adoption of a particular WHT will be influenced by the complexity of the technology, the source of innovation, availability of raw materials, and the costs and management of the technology.
