2015 IESS - Environmental And Socioeconomic Impacts Of Cage Aquaculture At Kpeve Tornu Section Of The Volta Lake

Cage aquaculture involves fish farming in floating cages in an existing water body that permits exchange of water, nutrients and waste materials between the cage and the water environment. While some experts claim that cage aquaculture negatively impacts on water quality, others found no significant impacts of fish farming in floating cages on water environment. While information on cage aquaculture abounds in some countries to enhance the industry, little information exist on the impact of cage aquaculture on the Volta Lake. Adequate data on the financial viability of cage aquaculture in Ghana is limited, and little is also known of the effects of fish farming on the Volta Lake on fishing communities. Information on compliance levels of fish farm owners on aquaculture regulations is also not much known.
The study therefore sought to examine these relevant issues at Kpeve Tomu, a fishing community in Afadjato South District in the Volta Region.

2015 IESS - An Assessment of Heavy Metals Content of Water, Soil and Plants in Some Selected Coastal Communities Near the Jubilee Oil Field in the Western Region of Ghana

This study investigated the concentration of seven heavy metals (As, Cd, Cu, Pb, Se and Zn) in water, soil and plant leaves in some selected coastal communities in the Western Region of Ghana near the jubilee oil field using acid digestion and Atomic Absorption Spectrophotometer methods.

2015 IESS - An Assessment of Dredging As a Tool for Managing the Effects of Sandbar Development at the Volta Estuary

The construction of dams on the Volta River and the consequent regulation of the river's flow pattern led to the development of a permanent sandbar at the Volta estuary that resulted in many problems for the estuary, with the major one being the disruption of salt water in-flow. Poor salinity conditions of the estuary resulted in, among other things, the development of freshwater plants which served as breeding grounds for some planorbid snails which harboured the parasites that cause schistosomiasis. Among the many efforts to solve the problem is the initiation of the ongoing dredging exercise at the estuary which started in 1990. The dredging project has been ongoing for more than twenty years now, but there exist little or no document for reference purposes. The purpose of this research therefore, is to assess the extent to which the exercise has succeeded in solving the problems.

2015 IESS - A Comparative Assessment of Phytoremediation and Slow Sand Filtration Technologies for the Secondary Treatment of Sewage Effluent and Public Views on the Use of Treated Effluent

This study evaluated and compared the performance efficiency of both technologies for treating sewage effluent from a Biogas facility at Valley View University (VVU) and also assessed public perception about the use of the treated effluent.
