dc.titleInnovative water management in irrigated rice fields: participatory demonstration approach to promoting alternate wetting and drying and tailwater harvesting in Ghana
dcterms.abstractThis report highlights the implementation of Alternate Wetting and Drying (AWD) and tailwater harvesting technologies in Ghana, targeting sustainable rice production in the Northern and Ashanti regions. AWD, a water-saving irrigation method, and tailwater recovery systems were demonstrated to optimize water use, reduce environmental impacts, and improve farm productivity. The initiative included demonstration plots, capacity-building workshops for Agricultural Extension Agents (AEAs), and farmer engagement activities to promote adoption. AWD has been validated to save up to 30% of irrigation water without compromising rice yields, making it a viable strategy to conserve water resources, mitigate greenhouse gas emissions, and lower production costs. Tailwater harvesting complemented these efforts by facilitating water reuse, enabling year-round agricultural productivity and the cultivation of high-value crops like okra. This diversified farm output improved dietary diversity and household incomes while enhancing the resilience of rice-based farming systems. To ensure broad adoption, a participatory approach was central to the demonstrations. Farmer Field Days (FFD) were organized as key training and knowledge-sharing events, showcasing the application and benefits of AWD and tailwater recovery systems. These events, held on December 4, 2024, in Botanga (Northern Region) and December 6, 2024, in Potrikrom (Ashanti Region), engaged over 100 stakeholders. Participants included farmers, researchers, extension officers, agri-input suppliers, irrigation managers, and policymakers, emphasizing the collaborative efforts required to advance sustainable rice production. Farmers who attended the FFD events gained practical knowledge on implementing AWD and tailwater harvesting to mitigate water stress during critical crop growth stages and improve yields. The events sparked significant interest, with many farmers expressing readiness to adopt AWD and complementary practices, such as tied ridging, to address challenges like erratic rainfall and water scarcity. Additionally, the events facilitated partnerships between farmers, extension agents, and researchers, fostering a collaborative environment essential for scaling sustainable practices across more rice-growing communities.
