The construction of the Bui Dam was expected to boost socio-economic development in Ghana. This article examines the impacts of the project on the livelihoods of the local people. Data were collected using a mixed-research approach and a case-study design. The study finds that, while there have been significant improvements with respect to resettlement and compensation issues as compared to the earlier dam projects in Ghana, there are still some shortfalls. It is recommended that agriculture be improved by providing extension services and inputs to improve food security and the economic status of the local people.

• Soil organic carbon (SOC) affected the mechanical properties of soil aggregates. • Water contents for tillage is determined using water retention and consistency approaches. • There is a strong positive relation between SOC and range of water contents for tillage (ΔθRANGE). • ΔθRANGE determined based on the consistency approach is recommended over the water retention approach.
