Abstract:

Abstract In Ghana, the Pwalugu Dam in the Upper East is in the final planning stage. Whereas promoters of Ghana's first dams emphasized the need for generating electricity to modernize and industrialize the new nation, the planners of Pwalugu have focused on water issues. Due to climate change, droughts have had a devastating impact on local agriculture. The dam's primary purpose is an irrigation scheme and flood control. This essay historicizes these concerns by revisiting the Akosombo Dam, Ghana's largest hydroelectric dam, completed in 1965. The discussion juxtaposes personal recollections of dam-affected communities with reports by administrators, biologists, and social scientists. The essay draws on government records, scientific studies about Volta Lake, and oral histories. Ultimately, it argues, builders and administrators of the Akosombo Dam failed to address most water issues, despite ample knowledge about their existence. One hopes that these shortcomings will not be repeated in the Pwalugu project.

Abstract:

In this study, an Autoregressive Integrated Moving Average (ARIMA) model was used to forecast Ghana’s Akosombo dam level and hydropower generation by the end of year 2022. Data used for this study span from January 2010 to December 2019. Base on the final ARIMA model, power generation is forecasted to decrease from 398 Megawatts/hr in December 2019 to approximately 374 Megawatts/hr by December 2022. On the other hand, water level of the Akosombo dam is predicted to decrease marginally from 264.8 ft in December 2019 to approximately 255.19 ft by December 2022. The Volta River Authority (VRA) and managers of the electricity production in Ghana are encouraged to be proactive in expanding energy production by turning more to renewable energy sources. In the coming years, as they seek to provide sustainable electricity for their cherished customers, investment decisions should be directed towards protecting the volta river from drying up due to human and climatic activities as well as expanding energy mix.

Abstract:

ABSTRACTAkosombo Township, designed by the Greek urbanist Constantinos Doxiadis, is the model city at the foot of the hydroelectric Akosombo Dam, Ghana's largest development project. The article explores different visions of high modernist planning for Akosombo and juxtaposes it with the desires for and imaginations of modernity among its residents. Officials of the Volta River Authority, the agency in charge of the township, promoted specific ideas about housing, husbandry, and hygiene, while residents engaged with and resisted this kind of social engineering. These tensions came to the fore, when the squatters of Combine struggled to remain in the township. In conversation with residents, VRA officials produced a form of ‘high modernist local knowledge’.

Abstract:

Dams are very important in Ghanas economic development and environmental improvement. Although Ghana dams are seismically far from the active zone, accurately analysed dams should be evaluated since failure could severely impact the people in the flood environment and the regions economy on a large scale. This paper proposes a numerical procedure for the static, slope stability, and dynamic analysis of the Akosombo embankment dam. Nineteen horizontal acceleration time histories recorded data was used based on Maximum Design Earthquake (MDE), Maximum Credible Earthquake (MCE), Design Basis Earthquake (DBE) and Operating Basis Earthquake (OBE) data. The numerical results estimated showed that the Akosombo embankment dam is likely to experience moderate deformations during the different design earthquakes. The result also indicated that non-linear analysis capable of capturing dominant non-linear mechanisms could be used to assess the stability of embankment dams. The factor of safety (FS) calculated was greater than 1.5 for high reservoir, rapid drawdown condition and low reservoir condition whereas, the FS values were found to be 1.42 for slow drawdown condition.

Abstract:

The Volta River in West Africa is one of the most regulated rivers influenced by dams in the world, and the regulation has resulted in substantial impacts on the hydrological alteration and morphological evolution of the Volta River Delta. However, comprehensive analyses of the relevant effects are still lacking to date. In this study, inter-annual variations of river discharge and sediment load for pre- and post-Akosombo Dam periods (1936 to 2018) were analyzed through simple regression and Mann–Kendall (MK) trend analysis whereas the intra-annual variations were dictated by the non-uniformity and regulated coefficients. The shoreline changes were further evaluated using Landsat remote sensing images (1972 to 2018) to explore the effects of hydrological alteration on the morphological evolution of the Volta River Delta. Hydrological analyses show that the inter- and intra-annual variations are much higher in the pre-dam period, suggesting the substantial regulation of the Akosombo Dam on the Volta River. The dam regulation has more significant effects on the sediment load delivered to the delta than the river discharge, which decreased by 92.32% and 23.23%, respectively. Morphological analyses show that the progradation-erosion of the Volta River Delta constantly fluctuates within a relatively small range (maximum 0.5%) after the 1970s. The relationship between the variations of the delta area and sediment load implicates that a quasi-equilibrium state may have been established at the Volta River Delta, given the current sediment load. Our findings provide references for the future regulation and restoration of the Volta River Delta.

Abstract:

The construction of the Akosombo dam in 1964 and the Kpong dam in 1981 on the Volta River created the Volta Lake in Ghana, West Africa. The purpose of this study was to examine the effects of dam construction on schistosomiasis prevalence. Several reports from numerous sources which together spanned a period of time from before the dams were built to recent years were analyzed. Four representative villages were chosen based on their locations with respect to the dams. Also examined were the efforts made by local health authorities to combat the current problem and to what degree their efforts have been successful. A marked rise in schistosomiasis prevalence following dam construction is observed in villages located in close proximity to the Volta Lake. In villages where aggressive action has been taken to correct this problem, a significant decrease in disease prevalence can be seen, demonstrating the importance of implementing proper disease control measures.

Abstract:

The Volta River is a West African river that flows from Burkina Faso to Ghana where it empties into the Atlantic Ocean. It basin extends over six countries: Benin, Burkina Faso, Côte d’Ivoire, Ghana, Mali and Togo. These states, members of the Volta Basin Authority, have committed themselves to drawing up a Water Charter. One of the challenges of this international agreement is to agree on a reasonable level of abstraction to reconcile food and energy security for the populations, while guaranteeing the minimum needs of the ecosystems. Supported by an appropriation of the needs-resources balance through the use of Lego® bricks, their reflection was supported by a hydro-economic analysis. This analysis consisted in comparing the added value associated with an agricultural abstraction - which leads to a definitive consumption of water upstream of the basin, for example in Bagré in Burkina Faso - and the one associated with the same quantity of water if it had been allowed to flow and turbined in one of the hydroelectric facilities located further downstream, for example in the large Akosombo dam in Ghana. The results show that the agricultural valorisation of a continuous abstraction of one m3/s, i.e. 30 Mm3 per year, allows to irrigate 1,500 ha and generates an added value of 1,300 M FCFA per year, i.e. 44 FCFA/m3. This volume of 30 Mm3, taken upstream of the dam would induce a loss of hydroelectric production of 6 GWh/year, worth 297 M FCFA, i.e. 10 FCFA/m3. The economic value of each m3 withdrawn to develop irrigated agriculture upstream of the basin is thus higher than that of each m3 turbined in the Akosombo-Kpong complex. Within the limit of an acceptable reduction of hydropower production, the economic development of the basin as a whole would thus benefit from the development of irrigated agriculture.

Abstract:

The costs of the multiple benefits of large-scale dam development are disproportionately borne by displaced people upstream and downstream riparian communities whose livelihood strategies have depended on the flood regime of rivers and resources in their natural surroundings. Downstream dam-affected populations are compelled to adapt to post-dam flood plain ecosystems in order to rebuild their livelihoods. However, they are usually confronted with many challenges due to limited local capacity, levels of vulnerability and impoverishment and, very often, inadequate and slow governmental and institutional support. In this paper, we examined the support of an international non-governmental organisation for four island communities of the Volta Delta in Ghana whose livelihoods were disrupted by the damming of the Volta River upstream at Akosombo, 80km from its mouth. The study was situated within the context of the sustainable livelihood analysis framework and the methodology adopted involved discussions and interviews with project beneficiaries and implementers. The study findings indicated that there were initial benefits from the livestock component of the project but that could not be sustained as the beneficiaries could not buy feed on regular basis. However, the communal agroforestry undertaken by the groups provided the impetus for establishment of individually-owned woodlots which are harvested for fuel. A key lesson from the project is that local leadership is crucial in the success of community livelihood support programmes. Also, adequate sensitization and education about the project along with re-orientation of peoples’ minds are essential ingredients for achieving acceptability of the project by local communities and ensuring project sustainability.
