Can communities close to Bui National Park mediate the impacts of Bui Dam construction? An exploration of the views of some selected households

“…Some adverse effects of the Bui Dam include loss of community lands such as farmlands, loss of both food and cash crops, an increase in the cost of conducting some livelihood activities such as fishing, and the influx of migrants who compete for available opportunities in community livelihoods. The study results is similar to the arguments advanced by several literature (Ofori-Amanfo, 2005;Dzodzi, 2006;Cave et al, 2010;Miller, 2011;Ansar et al, 2014;Chen et al, 2016;Fernside, 2016). The Bui study also confirms the results of WCD (2000), Galipean et al (2013) and Nusser (2014), by showing that dams can negatively affect livelihoods of people and families living near dams, and those who in some cases have gone through resettlements.…”

“…Dams have social cost and implications including the worldwide dam-related displacement of 40 to 80 million people (WCD, 2000;Krueger, 2009;Chen et al, 2016). In other cases of dam impacts, communities become displaced and resettled, whilst some people are also deprived of access to resources and assets such as farmlands, roads, and health and educational resources (Ferraro et al, 2011;International Rivers, 2013;Fernside, 2016).…”

An Overview of Hydropower Reservoirs in Brazil: Current Situation, Future Perspectives and Impacts of Climate Change

“…Pringle et al [43] relate some fish-related effects: population fragmentation and isolation, migration interference, increases in exotic lentic-adapted species (non-native fishes) and the threat of extinction of some species. Therefore, dams are fundamental for the maintenance of society; however, one must think about environmental sustainability and socio-economic impacts, i.e., the best way to build, operate and maintain dams [44].…”

“…Regarding their main use, 39% were built for power generation, 29% for irrigation, 14% for flood control, 8% for water supply and 10% for other uses [44]. The reduction in growth rate of number dams built since the 1990s is due to social and environmental concerns, high financial costs and reduction of favorable locations [44].…”

“…Regarding their main use, 39% were built for power generation, 29% for irrigation, 14% for flood control, 8% for water supply and 10% for other uses [44]. The reduction in growth rate of number dams built since the 1990s is due to social and environmental concerns, high financial costs and reduction of favorable locations [44]. In Brazil, there was an increase in the deployment of large hydroelectric plants in the 1960s and 1970s due to changes in tax criteria, followed by a reduction in construction of new developments in the 1980s and 1990s due to higher inflation and two oil shocks [46].…”
