Abstract:
Irrigation projects are important for food security; however, water requirements for sustainable irrigation may be affected by climate change. Climate change is projected to have significant impacts on agricultural production. Therefore, understanding the regional impacts of climate change on irrigation demand for crop production is important for watershed managers and agricultural producers to understand for effective water resources management. For irrigation project, the climate change affects it through the erosion, sedimentation in reservoir, flood, drought, etc. These impacts was be assessed in this research and measures were be taken for maintaining the irrigation system in Cyaruhogo wetland. The specific objectives like identifying the source of water for irrigation at Cyaruhogo wetland, assessing the cause of sedimentation in irrigation reservoir and Results analysis and discussion according to the laboratory tests were be used for achieving on the goal. To reach on objectives, interview were be conducted according to the prepared question for sample population in beneficiary area. The PH of water was be tested in laboratory to know if the irrigated water has acceptable PH for supporting crops. The PH of water in chemical analysis is 6.91 which is in acceptable limit, electrical conductivity is 374.4µs/cm and it is in range. The sediment has measured in laboratory and then the total sediment per year each dam is 13440tons, 11600tons and 13440 tons to Cyimpima, Bugugu and Gashara respectively. So the erosion control structure is needed to reduce the sediment enters in dam for maintain the capacity of water storage and keeping the product rises from Cyaruhogo wetland.
