The socio-economics dynamics of Dam on Rural Communities: A case study of Oyan Dam, Nigeria
Amidu Ayeni and Lawrence Ojifo Department of Geography, University of Lagos, Nigeria
Abstract. Dams construction and operations have many benefits, nevertheless, they have also led to lots of negative social, health and human impacts. It is based on this that this study assesses the potential and socio-economics dynamics of Oyan dam between 1980 and 2016. The data used for this study include water level and discharge records of the dam between 2007 and 2016, Landsat imageries of 1984 and 2016 and socio-economic datasets for the period. Analysis of the dam potentials (water supply, agriculture and hydropower) and socio-economic impacts of the dam were carried out using basic statistical tools, land use change anaysis and field survey using questionnaire, structured interview with major stakeholders and personal observation. The results revealed that the water level and storage of the Oyan dam had a relative reduction of about 2 % as well as non-stationarity pattern of water abstraction and production for the period. The landuse classes show all classes decreased in extent except the cultivated landuse that acrued an increased of 19.9 % between 1984 and 2016. Furthermore, commercial water supply varied significantly between 2010 and 2016 while irrigation scheme is grossly under-utilized from the inception in 1983 to 2016. Finally, the result of socio-economic impacts revealed that majority of the selected communities' members are actually not benefiting from the dam and their livelihoods are not from the dam.

Short summary
This study assesses the potential and socioeconomic dynamics of Oyan dam, Nigeria. The data used include discharge records, Landsat imageries and socioeconomic data sets. The results revealed that the water level and storage had reduction of about 2 % as well as non-stationary pattern of water abstraction and production. Only cultivated land-use accrued an increased between 1984 and 2016. Commercial water supply from the dam varied significantly while irrigation scheme is grossly under-utilized.
