Figure 9.28 | Tens to hundreds of millions of people in Africa are projected to be exposed to sea level rise, with a major risk driver being increased exposure due to population increase in low-lying areas.

(a) Population in the low-elevation coastal zone (LECZ) projected to be exposed to mean sea level rise (SLR) for 2030 (+10 cm SLR) and 2060 (+21 cm SLR). Scenarios A, C have exclusive social, political and economic governance whereas scenarios B and D have inclusive social, political and economic governance.

(b) African countries with the highest projected population numbers in the LECZ, and also the additional population projected to be exposed in these countries due to a 1-in-100 year storm surge event. For panel b projections of population exposure used the high population growth socio-economic scenario (scenario C). Data sourced from Neumann et al. (2015).
