Laboratory analyses of water, soil and socioeconomic data at household as well as atrncommunity level and secondary data from health centers were used to generate importantrninformation that help to evaluate impacts of community- based irrigation.rnRes ults indicate that some of the water-related diseases are declining and others arernincreas ing. Prevalences of animal and plant diseases are high and need immediaternintervention.rnThe water and soil condition at Ziway arc getting deteriorated so badly that thernsusta inability of the scheme became questionable. The water and soil at Holota arerncurren tly in a good condition to support production. However, it needs good managementrnto minimize the future risks.rnSocio-economic conditions of the two schemes have improved with the introduction ofrnthe irri gation scheme but their efficiencies are influenced by external factors that need tornbe counteracted.rnThe study investigated the need for the environmental impact assessment indicators thatrncarefully planned and designed scheme will improve the benefit of the community-basedrnirrigation.rnCommunity level discussion revealed opportunities and constraints that contribute tornen hance the sustainability and equally their fail~lre.
