This study was conducted to assess vulnerability of West African countries to climate change using selected indicators for adaptive capacity, exposure and sensitivity to generate vulnerability index for West African countries. Vulnerability index was calculated as the net effect of adaptive capacity, sensitivity and exposure to climate change. Principal Component Analysis (PCA) was used to assign weights to the vulnerability indicators used in this study. A total of thirteen (13) indicators were used to generate vulnerability index and vulnerability maps were produced using the GIS software package ArcGIS 10.2. The result shows that Niger, Mali and Mauritania have the highest levels of vulnerability to climate change in West Africa. The countries with the least levels of vulnerability to climate change are Ghana, Cape Verde and Gambia. Generally, this study shows that most countries in West Africa are vulnerable to climate change with ten countries (Niger, Mauritania, Mali, Burkina-Faso, Liberia, Senegal, Guinea Bissau, Guinea, Benin and Sierra Leone) having vulnerability levels higher than 50%. We conclude that there is the need for well planned integrated adaptation measures to reduce the impact of climate change in the region.
