An application of GIS and coastal geomorphology for large scale assessment of coastal erosion and management: a case study of Ghana

The ecological effects of beach sand mining in Ghana using ghost crabs ( Ocypode species ) as biological indicators

“…All three colonial castles that have been designated as World Heritage Sites by UNESCO in Ghana are located along the coastline of Cape Coast and Elmina and attract visitors from within and outside Ghana (Boateng, 2012). In recent years several tourism facilities have been developed in these areas to take advantage of the coastal touristic industry.…”

A Biophysical and Socioeconomic Review of the Volta Delta, Ghana

“…Reworking of the sediments of the coastal plain to sustain the longshore drift dynamics and beach mining has further worsened the erosion situation. Coastal erosion has destroyed properties, reduced livelihoods, displaced households, and widened gender gaps as women often bear a disproportionate share of the social costs (Boateng, 2012;Ofori et al, 2016). Climate change and its associated sealevel rise pose major challenges to the sustainability of deltas globally (Nicholls and Cazenave, 2010;Syvitski, 2008).…”

“…a managed retreat or 'managed realignment') in managing erosion and flood problems in the delta (Nicholls et al, 2013). Lack of effective coastal erosion management policies has also prevented adoption of an integrated approach in managing erosion and flood problems (Boateng, 2012).…”

“…The sand spits and barriers associated with the Volta delta are highly dynamic (Anthony, 2015). It also depicts the effect of human developments in the region (Boateng, 2012). The large spit of the Volta delta is a direct outgrowth of a natural change in the location of the mouth of the Volta and of a marked reduction in sand supply that predated the construction of the Akosombo Dam, but which has been strongly aggravated since the dam was constructed and the annual flood-flushing of the river mouth ceased (Anthony, Almar, and Aagaard, 2016).…”

Hindcasting sand spit morphodynamics after groyne construction in Ghana

“…Along the northwest coast of Africa average rates of coastal retreat are between 1 and 2 m/year (Appeaning Addo 2011;UNESCO 2012). For the eastern coast of Ghana the coastal retreat has been estimated to be around 4 m/year (Boateng 2012b).…”
