Abstract
Climate change and its association with sea-level rise {u2018}SLR{u2019} have become a fact that increasingly challenge coastal zones all over the world. While African coasts are threatened by SLR, its deltas are the most threatened due to their high spatial and developmental features. The studies about the vulnerability of African deltas are scarce. This study attempts to fill a part of this gap, as it introduces a recent study by using remote sensing and available data associated with GIS and ENVI analysis. Firstly, this study aims to develop a practical framework to assess the coastal vulnerability of the African deltas to SLR impacts based on analyzing a group of different theoretical studies. Secondly, this study aims to assess the vulnerability of African coasts based on a quantitively parameterized model by using the coastal vulnerability index (CVI). Thirdly, this study aims to assess qualitatively the vulnerability faces of African coastal deltas by using a multi-case study approach, the study applied on three of the major coastal deltas in Africa: Nile, Niger, and Zambezi deltas. Fourthly, the study aims to recommend some SLR adaptation policies and strategies for these studied deltas. There are seventeen parameters used to assign CVI results. Application of CEI showed that about 40% of African coast are ranging from moderate to very high exposure, as for the CSI showed that 75% of African coast are ranging from moderate to very high sensitivity, as for the CRI showed that 55% of African coast are ranging from moderate to very high resilience, and as for the CVI showed that 35% of the 26,000 km length of Africa’s coast is vulnerable to SLR.The following coastal areas were highlighted as very highly or highly vulnerable areas; South Somalia, Zambezi Delta, Togo, and Benin. Moreover, due to variation in the rated value of exposure and sensitivity factors, moderate vulnerable areas exist in some coastal parts in Kenya, Tanzania, Mozambique, Angola, Zaire, Cameroon, Nigeria, Ivory Coast, Liberia, Sierra Leone, Guinea, and Senegal
