Working PapersThe publications in this series record the work and thinking of IWMI researchers, and knowledge that the Institute's scientific management feels is worthy of documenting. This series will ensure that scientific data and other information gathered or prepared as a part of the research work of the Institute are recorded and referenced. Working Papers could include project reports, case studies, conference or workshop proceedings, discussion papers or reports on progress of research, country-specific research reports, monographs, etc. Working Papers may be copublished, by IWMI and partner organizations.Although most of the reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each report is reviewed internally by IWMI staff. The reports are published and distributed both in hard copy and electronically (www.iwmi.org) and where possible all data and analyses will be available as separate downloadable files. Reports may be copied freely and cited with due acknowledgment.

Dependence of Riparian Communities on Ecosystem Services in Northern Ghana
SummaryNatural infrastructure supports large parts of the rural communities in northern Ghana through the generation of ecosystem services that it provides. The provisioning of ecosystem services is a function of the seasonal nature of the climate in northern Ghana. Natural infrastructure enables food provision, which translates into food security and generates income through the year while providing an important safety net during the dry season. Rainfall is concentrated in the period from May to September followed by a long dry season. The river, responding to the climate, shows similar seasonality, flooding large parts of land during the rainy season and drying up during the dry season. Natural water infrastructure supporting riparian communities, such as headwater catchments, wetlands and seasonal floodplains, is affected by water resource development decisions. This study investigated the dependence of three riparian communities on ecosystem services in northern Ghana. In particular, the role of natural water infrastructure in supporting these ecosystem services. Participatory mapping and ranking exercises in gender-segregated groups were used to elicit information on the communities' livelihoods. The riparian communities are dependent on five types of natural infrastructure: forest reserves, shrubs and woodlands, riparian ponds, the White Volta River and floodplains. Different ecosystem services are derived from natural infrastructure and these enable livelihood activities. The most important activ...
