Abstract
Most of Sub-Sahara African countries have been trying to introduce Participatory Irrigation Management (PIM) to obtain efficient and sustainable irrigation management. Collection and management of Irrigation Service Charge (ISC) by water users' association are crucial issues for successful PIM, while low incentive for farmers to pay ISC is widely seen. This paper aims to analyze, using questionnaire, contrastive differences in ISC management found in two model projects in the Small Scale Irrigated Agriculture Promotion Project (SSIAPP) in Ghana supported by Japan International Cooperation Agency (JICA) for 7 years from 1997. Results suggest that making use of outer conditionsuch as diversified use of ISC money combined with farming activities, as well as accountability and transparency in the association management, is effective to enhance the collection ratio of ISC.
