Adoption and Impact of Water Harvesting Techniques in Jordan

Water harvesting has become a main priority in the low rainfall areas of Jordan due to high increase in population growth and limited water resources. The specific objectives of this study are to assessing the rate of adoption of water harvesting technologies and identifying main constraints that limit the adoption process in the low rainfall areas of Jordan and Identification of performance indicators for water harvesting techniques, related to efficiency, and environment sustainability and to assessing the impact of alternative water harvesting techniques in the low rainfall areas of Jordan. Descriptive and econometric analyze were used to study community characteristics and adoption rate was estimated by the logistic model. Results of the study showed that the IRR of planting barley with water harvesting was more feasible than planting barley in the farmer practice where the IRR is estimated at 17% compared to 7.85 for the farmer practice. The incorporation of the environmental benefits into the calculations of the return to investment for shrubs resulted in having FIRR equal to 36% and EIRR equal 17% compared to 28% and 17% respectively.
