Intervention Emerging results / key findings
• Manual/motorized water-lifting devices:Rope and pulley, Rope & Washer, motorpump, solar pump
• Irrigation management: irrigationscheduling tools, e.g. TDR, Wetting FrontDetector
• Crops: High–value vegetables, fruit trees,fodder crops
• Groundwater recharge improvement:Berken plow, biological treatments
• Credit access: facilitated through localfinancial service providers
• Groundwater availability and sustainabilityfor dry season SSI not be feasible in someareas; on farm water management isimportant
• Groundwater recharge (in Ethiopia) can beimproved using deep tillage
• Irrigation scheduling tools and fertilizerguidance needed to optimize water use andproductivity
• Most Irrigation technologies are profitablewith high value vegetables (crops)
• Labor constraints and costs are key factorin profitability
• Access to appropriate financing is low;access to credit may increase adoption
• SSI technology supply chain isunderdeveloped

PROBABILITY OF IRRIGATION ADOPTION AND WATER SCARCITY
High adoption probability for SSI at Lake Tana and Ethiopian Highlands, and Great Rift Valley areas
SSI development may pose widespread water scarcity
