The lack of a significant tradition of irrigation in much of Africa is one of the factors reducing effectiveness of irrigation development. It is therefore difficult to forecast the rate of technology uptake and therefore expected increases in productivity on regular schemes. In Zimbabwe, a study by Rukuni (1984) has shown that small-holder irrigators have severelylimited resources, though they may be relatively better off than their counterparts on rainfed plots. The situation of farm families on Zimbabwean small-holder schemes has been found to differ between 3 main types of schemes. These are (a) the older type government schemes, (b) the younger type of government schemes and (c) those run by ARDA (Agricultural and Rural development Authority; a parastatal) as part of a large State farm. The older type government schemes are more "intensive" and individual families have more land than the younger "supplementary" schemes. The farmers on supplementary schemes integrate irrigation with rainfed agriculture more strongly. Families generally face a number of resource constraints. First is the problem oflack of draft power on government schemes. ARDA farmers have access to tractors. Farmers also generally face labor shortages at certain times of the year, especially in the production of crops like cotton or tomatoes. Farmers also face cash shortages at times. This affects the use of purchased inputs. Whilst it is easy for ARDA farmers to acquire credit, this is more difficult for those on government schemes.

(Location: IWMI-HQ Call no: PER Record No: H018668)
This paper describes the application of an economic incentive program to achieve water quality objectives by motivating improvements in farm-level water management practices. The program incudes farm-specific water allotments, tiered water pricing, and low interest loans for purchasing irrigation equipment. The implementation of this program in a California water district has resulted in significant reductions in irrigation deliveries and drain water volume. Since the program was implemented, average irrigation depths have declined by 25% on cotton fields, 9% on tomatoes, 10% on cantaloupes, 30% on seed alfalfa, and 29% on grain fields. The average volume of drain water collected each year in subsurface drainage systems has declined from 4.8 million m3 during 1986 through 1989 to 2.6 million m3 during 1990 through 1993. These results confirm that economic incentives can be effective in generating improvements in water quality.
