Assessing the Impact of a Dam on the Livelihood of Surrounding Communities: A Case Study of Vea Dam in the Upper East Region of Ghana

River basins are well known as the origin of advanced human social development and cultural heritage which ancient and modern communities have depended on for livelihood, commerce and habitat. Dam is one of the many man-made alterations to river basins that have been built for centuries and without doubt have contributed to the development of many nations. However, their social, health and environmental impacts have in too many cases not been assessed most often in developing countries. This research sought to explore and understand the Vea Dam within the context of socio-economic and health impacts on the host communities. Secondary data were collected from Irrigation Company of Upper Region and Bongo District Assembly in Ghana whilst primary data were obtained through random and stratified sampling. The results revealed that 2.6% and 66% of the respondents are employed in the fishery sector and irrigation sector, respectively. The dam necessitated the relocation of about 34% of the communities and on the average two people are drown annually in the Dam. The prevalence of water borne diseases after the construction of the Dam was also perceived by the communities to have increased. The Dam has both positive and negative socio-economic and health impacts on the surrounding communities with the benefits outweighing the negative impacts. The availability of potable drinking water in the area has created development with inevitable rise in standard of living. The study also revealed that agricultural activities, freshwater fishery and availability of water for irrigation of farmlands have improved. However, an enhancement in the beneficial impacts and minimization of the adverse impacts would help better livelihood in the communities.
