Identified Barrier #2 to climate-resilient water management in Tanzania

The objective of the study was to assess irrigation practices in the Upper Ruvu catchment of the Wami-Ruvu basin, specifically along the Ruvu river, with the overall aim of understanding the current situation on the performance of irrigation practices and examining root causes of irrigation inefficiencies. [...] Specific objectives • Assess the performance of the existing irrigation schemes in the Upper Ruvu catchment • Examine the root cause of the low irrigation efficiency in the Upper Ruvu catchment • Recommend intervention measures to address the low irrigation efficiency in the Upper Ruvu catchment that ideally can be replicated preventatively across other catchments Expected outputs, outcome and imp. [...] To address the growing scarcity in the basin, this analysis investigates the root cause of efficient agricultural irrigation in the Basin and recommends options for reducing the amount of water used by irrigated agriculture. [...] 8 Situation analysis of the performance of irrigation schemes in the Upper Ruvu catchment Irrigation practices and infrastructure in the Upper Ruvu catchment Irrigation practices in the Upper Ruvu catchment In the Upper Ruvu catchment, which constitutes a significant portion of the water demand within the Wami- Ruvu Basin (M. [...] In field surveys of the operations of the Mbalangwe and Tulo Kongwa irrigation schemes, the efficiency was observed to be very low because the volume of water that is needed and used by the crop far exceeds the volume delivered to the field, as most withdrawals did not consider the crop water requirements but the infrastructure capacity.
