The purpose of this study was to assess the constraints to the utilization of rainwater harvestingrnponds by farmers in Derra woreda, Oromia region. To achieve the objectives of the study, thernresearcher collected primary data through household questionnaires, interviews with variousrnofficials and key farmers as well as group discussions with PA level administrators; andrnsecondary data from written materials. The collected data were analyzed through bothrnquantitative methods like frequencies, percentages and significance tests; and throughrnqualitative methods.rnThe results of the study disclosed that most farmers have good perceptions for the technologyrnand have gained enough awareness about the benefits obtained from the ponds. But, thernutilization of the technology is surrounded by various constraints. The major constraints include:rnthe low quality of the constructed and hence short service duration of the ponds; inferiorrnutilization of the stored water resulted mainly from low involvement and from limited training ofrnstakeholders during the implementation of the program, and from the wrong site of the ponds.rnFurthermore, high cost of construction has hindered farmers not to have additional ponds; andrnlimited financial power of farmers has resulted in low maintenance of old ponds and alsorndecreased the capacity of farmers of purchasing materials and equipments to utilize therntechnology. Low investigation of soil types and ground slope by experts during the constructionrnperiods have contributed to the existence of unutilized ponds. The results of the study alsornidentified that the incidence of local disputes among the society and reducing cultivation land asrna major negative impacts that the unutilized ponds have exerted on the community. From thernresults of the study it is also known that households with large family labor, better land size andrnoxen, and better income have better possibility of utilizing the technology than theirrncounterparts.rnOn the basis of the findings, it is recommended that the government shall give due attention for the construction of quality and long lasting ponds; facilitate ways for the involvement of NGOs in the technology; create financial institutions assist technology users; and repairing or closing of unutilized ponds through mobilizing the community
