Feasibility assessment of climate change adaptation options across Africa: an evidence-based review

Abstract Considering the feasibility and effectiveness of adaptation options is essential for guiding responses to climate change that reduce risk. Here, we assessed African context. Using Global Adaptation Mapping Initiative, a stocktake adaptation-related from peer-reviewed literature in 2013–2020, found 827 records actions Africa. We categorised evaluated 24 each option, six dimensions were considered: economic, environmental, social, institutional, technological, evidence effectiveness. Over half (51%) all reported food sector where sustainable water management (SWM) was most option. The fewest cities (5%). majority (53%) recorded just countries: Ghana, Ethiopia, Kenya, Tanzania, Nigeria South Encouragingly, as medium or high 95% options. However, no had on any other dimension. Technological institutional factors present major barriers implementation. Crop management, SWM, agricultural practices, agroforestry, livelihood diversification, ecosystem governance planning, health infrastructure built environment, moderate across three more dimensions. Human migration has low but potential risk reduction. Major knowledge gaps exist environmental feasibility, assessing limits at increasing levels hazard, economic trade-offs synergies, Central Northern Our results highlight sectors enablers can be increased. Future assessments apply method established here extend findings national local levels.
