Promoting rainwater harvesting for improving water security: Analysis of drivers and barriers in Ghana

The study explored strategies and means of achieving wider acceptability and adoption of roof rainwater harvesting (RWH) systems in Ghana to improve water security and availability. The paper employed a qualitative approach in analyzing views expressed by a wide range of stakeholders participating in a workshop on the potential for up-scaling successful RWH technology. Dialogue and content analysis of the views on drivers and barriers to the uptake of RWH technology on a wider scale were synthesized to establish the sustainability of the technology. Some drivers identified included encouraging local fabrication industries to design and/or develop RWH installation components; using the cluster approach in the implementation of RWH technology to ensure cost-effectiveness and wider adoption of the system; and employing the media including television and radio to disseminate the socioeconomic and environmental benefits of the RWH system. Barriers to adoption of the RWH system identified included limited infor...
