Sea Level Rise Map

Sea Level Rise

Sea level rise hazard profile development used the worst case scenario of maximum level of sea rise of about 59 cm in 100 years predicted in 2007 by the Intergovernmental Panel on Climate Change   (IPCC). However, literature indicates high uncertainly in sea-level rise predictions due to the lack of understanding of the dynamics of ice sheets, glaciers and oceanic heat. 

The accuracy in the modelling of sea level rise depends on two parameters namely the accuracy of sea level prediction and accuracy of ground level heights.

Potential impacts of sea level rise in coastal areas within the next 25 to 100 year period was studied. The sea level rise maps covering the entire coastal belt indicating the inundation areas in 2025, 2050 and in 2100 were prepared. It is important to note that sea level rise predictions used only one type of elevation data, namely the ASTER GDEM that are of a coarser resolution (30m). Users should be mindful of the inaccuracy in the areas modelled using the ASTER datasets.

Sierra Leone’s coastal areas are increasingly vulnerable to the impacts of global climate change. The combined effects of sea level rise and environmentally unsustainable practices such as mangrove deforestation and sand mining are expected to result in accelerated rates of coastal recession and destruction of infrastructure.

Over 2 million people along coastal areas in Sierra Leone are expected to be at risk from predicted sea level rise. In addition to loss of properties and beaches, the consequences of sea level rise include population displacements, flooding and saline intrusion, and threats to coastal aquifers, fresh water resources and agricultural water resources, undermining subsistence of local communities (UNDP)[1].
