Agriculture is a key sector of the Rwandan economy; it contributes approximately 33% to the gross domestic product and employs more than 70% of the entire labour force. Although some farmers are already using water-efficient irrigation infrastructure, too much of the available water is still lost due to unsustainable use of existing irrigation systems, and/or maximum crop yields are not achieved due to under-irrigation.
Hence, small to medium-sized food producers in Rwanda do not have sufficient access to information regarding optimal irrigation practices. To close this information gap, FutureWater has devised an innovation that can calculate a location-specific irrigation advice based on Virtual Weather Stations, expressed in an irrigation duration (“SOSIA”). The use of the outdated CROPWAT 8.0 method, and the lack of good coverage of real-time weather stations in Rwanda, means that current advice falls short. In addition, existing advisory services are often too expensive for the scale on which small to medium-sized farmers produce. There is a potential to increase the productivity of the irrigation water by up to 25%. Initially, the innovation will be disseminated via the Holland Greentech network, with a pilot in Rwanda consisting of 40 customers.
FutureWater has found with Holland Greentech an ideal partner to roll-out this innovation due to their presence in and outside of Rwanda, where they provide irrigation kits and advice. This offers the opportunity to quickly scale-up the proposed innovation. With their expertise in agro-hydrological modeling and the African agricultural sector, FutureWater and Holland Greentech respectively have acquired ample experience to make this innovation project and its knowledge development to a success.
