Detection, Measurement and Prediction of Shoreline Change in Accra-Ghana : Shoreline recession analysis and modelling under the scenario of climate change in a data starved environment
Bok av Kwasi Appeaning Addo
Information about shoreline evolution
trend has influenced coastal policy formulation and enabled
development of sustainable coastal management practices
worldwide. Numerous studies have reported varied rates of
change ranging between 1.5 and 15 m/yr in Ghana's Accra
shoreline, a data starved nation. This has resulted in the
lack of effective and sustainable management of the coastal
resources. The study reported in this book addresses this
issue using mapping data from 1904, 1974, 1996 and 2002 to
estimate shoreline recession in the Accra region.
Predictions for the next 250 yr were then undertaken using
a variety of modelling techniques and accounting for
uncertainties. The rate of erosion in the Accra region was
found to be 1.13 m/yr (0.17 m/yr). Subsequent predictions
were used to identify a series of significant economic,
ecological and social features at risk, and to estimate
when they will most likely be lost to erosion if left
unprotected. The study illustrates that it is possible to
provide reliable statistical information in support of
sustainable coastal management for developing countries in
the face of a changing climate.
