Replicating the Woadze model in the Dayi basin, Ghana

The Dayi River basin lies in the southeast sub-tropical Ghana. This rural area has 144.000 inhabitants on approximately 1200 km2. The main economic activities are rain-fed subsistence farming and some cash crop farming. The average annual rainfall decreased from 1700 mm/year in 1975 to 1400 mm/year at present. The decrease in the amount and reliability in rainfall has had a negative impact on the traditional rain-fed agricultural practices. Precipitation is likely to decrease over the next 40 years and temperature is expected to rise by 2.5-3.0 °C.

The aims of this project, which is carried out in cooperation with the Development Institute (DI) and the Water Resources Commission (WRC), are to support successful farmer initiatives in sustainable small-scale irrigated agriculture to cope with the decrease in reliability of rainfall, and to work towards climate proofing the basin’s water management.

Local action

Based on a survey and on discussions with local farmers, a new management system for the area was designed, introducing various zones for activities: drought resistant crops; agroforestry; tree nurseries and small scale irrigation. The farmers also receive training in irrigated agriculture, as sprinkler irrigation schemes will be created in cooperation with these farmer groups.


Climate change adaptation in the water sector was put high on the agenda during the ADAPTS workshop in ACCRA in June 2009. Results of ADAPTS research contribute to the inclusion of climate change adaptation in the Dayi River basin management plan.

From now onward local communities must be represented in Basin Boards and have a voice in the management plan. Farmer groups are currently developing sustainable land management systems.
