Assessing the Climate Resilience of Sub-Saharan Africa (SSA): A Metric-Based Approach

Abstract

The impacts of climate change have resulted in the emergence of resilience as the de factor framework for countries seeking to capture the differential and uneven ability to prepare, react, respond and cope with volatile and rapid changes of climate-related stresses. Despite being considered by many researchers the most vulnerable region to the negative effects of climate change, the climate resilience of Sub-Saharan Africa has not been extensively studied. Using countries in Sub-Saharan Africa (SSA) as a study area, this paper constructed a pragmatically based resilience metric called the composite national climate resilience index (CNCRI) that can be used as a tool for the policy word. The inherent variables used to construct the CNCRI were justified and used to measure the resilience of countries in SSA based on five different dimensions. The result indicates that the CNCRI score, 1.05 (least resilient) to 44.8 (most resilient), and the island countries of Mauritius, Seychelles, and Cape Verde are comparatively more resilient than the rest of the countries in the study area. Regionally, Southern Africa is more resilient compared to East, West, and Central Africa. The vulnerability and readiness metric suggested that Cape Verde is the only country in SSA to have low vulnerability and high readiness, while most countries have high vulnerability and low readiness, making them the least resilient countries needing urgent mitigation and adaptation actions. Lastly, finding from this study could provide the policy world with insight for improving the overall ability to prepare and respond to the negative impacts of climate in the study area.
