Financial feasibility of irrigated farming: a case study of tube-well irrigation in Mombasa district
(University of Dar es salaam, 1978) Thiongo,Michael Nooroge
Where as some studies have evaluated large-scale irrigation schemes in Kenya,little economic research has been done The decision by the Kenya on the Minor Irrigation projects. The decision by the Kenya Government to increase emphasis on development of Minor Irrigation Schemes necessitates studies on these particularly from the financial and economic stand point. Tube-wells are part of the minor irrigation development programme in Coast Province which is characterized by a general shortage of big rivers and streams. This shortage of surface water in the Province in particular and generally in there public had been released even during the colonial days. Government efforts have been carried out mainly by construction of tube-wells, which progressed steadily so that by the early 1970s over 8O tube-wells were being bored annually by the Kenya Government. The substantial costs involved in this tube-well development were justified by the fact that the projects were undertaken by the Government or the Municipality for community water development. As such boring of tube-wells was restricted to the community centres only. Unfortunately most of these tube-wells especially those in Coast Province were abandoned when no personnel was available to maintain them. A survey of the area between Gazi and Mtwapa in Coast Province in 1969 to study the distribution of tube-wells, their yields,and water quality rated this as “a good area of ground water resources". It was recommended in this report that same selected tube-wells which were yielding considerable quantities of good quality water should be rehabilitated and fitted with powered pumps for the purpose of irrigation end domestic water supply. This recommendation was not implemented because information was lacking concerning their financial viability as irrigation projects. This thesis is therefore concerned with evaluation and appraisal of tube-well irrigation projects in Mombasa District to establish their financial worth Mombasa District was selected for the study on account of the concentration of tube-wells. The focus of the thesis involved collection of primary data from a sample of I0 farms using each diesel and electric pumps. Irrigated farming is capital and labour incensive. High initial investment capital is required to start-off a tube-well irrigation project. Because of the high costs involved in supplying irrigation water, only crops with high gross margins per hectare can be grown profitably. The study revealed that tube-well irrigated farming based on high-value horticultural crops can be a highly profitable venture if properly designed and planned Knowledge of the important factors affecting returns is invaluable. A high degree of managerial ability.innovativeness and first-hand market intelligence and knowledge irrigation techniques is in dispensable for successful irrigation. In spite of the high investment and running costs involved in tube-wells irrigation projects,they are financially viable and yield high rates of return to investment and internal rates of return.
