Abstract
A computer program model for pricing irrigation water among beneficiaries, was developed by the use of Turbo Pascal language. The data that was used to test the model was collected from Lower Moshi Farmer-Managed Irrigation System (FMIS) in Northern part of Tanzania as a Case Study area.The aim was to evaluate the costs involved in the process of allocating irrigation water with the objective of developing a computer program model appropriate for pricing irrigation water in FMIS in Tanzania. Allam’s (1987) mathematical model for allocating irrigation water price which was
developed in Egypt, was adopted and adapted for the purpose. The results show that the irrigation water prices obtained differ between different blocks within the same system, and also there is significant difference of irrigation water prices between two systems that exist in Lower Moshi Irrigation System (LMIS) i.e Rau and Mabogini. By manual calculations, Mabogini irrigation system’s water price ranges from 8,276 Tshs/ha to 14,972 Tshs/ha; while for Rau system it ranges from 3,896 Tshs/ha to 13,857 Tshs/ha; with their mean values of 11,940 Tshs/ha and 10,538 Tshs/ha
respectively.The computer program model produced irrigation water prices ranging from 8,479 Tshs/ha to 15,200 Tshs/ha for Mabogini system; while for Rau system they range from 3,913 Tshs/ha to 13,858 Tshs/ha, with their mean values of 12,151 Tshs/ha and 10,414 Tshs/ha respectively. The mean value was adopted as the system irrigation water price in each system.
The farmers’ capacity to pay Irrigation Service Fee (ISF) was also assessed and found to be 154,309 Tshs and 194,309 Tshs for tenant and landowner farmers respectively.The irrigation water pricing computer program model was tested for one cropping season. Therefore, more work is required to test it for the two cropping seasons, and in other FMIS so as to develop universal model. This will make it more universally applicable in Tanzania.
