    Economic valuation of irrigation water and riverside wetland services: the case of lower Moshi irrigation scheme in Tanzania
    (Sokoine University of Agriculture, 2010) January, Abiud
    This study was carried out to determine the economic value of irrigation water and riverside wetland services in the Lower Moshi Irrigation scheme. The specific objectives were to assess the economic value of water for irrigation, investigate the willingness to pay among smallholder farmers for riverside wetland services conservation in the Rau River and to assess factors that determine WTP for riverside wetland services conservation by water flows in the Rau River. The study counted on the data collected from 105 respondents from four villages of Lower Moshi in Kilimanjaro region which are Rau, Mabogini, Chekereni, and Oria. Data were analyzed using descriptive and quantitative methods. The Residual Computation Method was used to compute the economic values of irrigation water for paddy, maize and sunflowers. The Contingent Valuation Method was employed to elicit the willingness to pay for the riverside wetland services conservation, while the logit and linear regression models were used to assess the factors that determine willingness to pay for the riverside wetlands. The findings showed that, the economic value of water for irrigation for paddy was Tshs 366/m3, sunflower Tshs 448/m3 and maize Tshs 329/m3. The economic value for sunflower is high compared to that of maize and Paddy as compared to their profit margin. This is due to the fact that, sunflower use less water compared to other crops and mature early than paddy and maize. The results from CVM indicated that, the respondents were willing to pay an average of Tshs 27 860 per Ha per annum to conserve wetland services in the Rau River. The information on water's economic value enables decision makers to make informed choices on water development, conservation,allocation, and use when growing demands for all uses are made in the face of increased scarcity.
