Common questions
Answer-first, drawn from the same data above.
How risky is Sierra Leone?
Sierra Leone: mid-pack overall, with governance the main pressure. Its overall risk score is 55 out of 100 (medium), blended from World Bank, INFORM Risk Index and ND-GAIN Country Index.
What drives Sierra Leone's risk?
Sierra Leone's highest pressures are governance (77, high) and adaptation (70). Its strongest area is nature (36).
How might Sierra Leone's climate change by 2080?
Sierra Leone's climate zones stay broadly stable through 2080 even under a high-emissions scenario (SSP5-8.5); its Koppen-based climate-hazard pressure index holds near 76 out of 100. This forward-looking outlook is separate from the historical ND-GAIN scores.
How much will Sierra Leone warm by 2080?
Under a high-emissions scenario (SSP5-8.5), Sierra Leone is on track to warm by +3.0 °C by 2080, with annual precipitation changing by -126 mm; under lower emissions (SSP2-4.5) the warming is about +2.1 °C. Based on CMIP6 multi-model projections against a 1970-2000 baseline.
How much will sea levels rise along Sierra Leone's coast?
Coastal sea level along Sierra Leone is projected to rise by +0.79 m by 2100 under a high-emissions scenario (SSP5-8.5), and by about +0.59 m under lower emissions (SSP2-4.5). Based on the regional median of IPCC AR6 projections.
How will water stress change in Sierra Leone?
The share of Sierra Leone under high water stress is projected to move from 0% today to 0% by 2080 under a high-emissions scenario (SSP5-8.5). Based on WRI Aqueduct projections.
How will river-flood exposure change in Sierra Leone?
The share of Sierra Leone exposed to river flooding is projected to move from 5.6% today to 8.2% by 2080 under a high-emissions scenario (SSP5-8.5). Based on WRI Aqueduct riverine-flood projections.
When was Sierra Leone's risk data last updated?
Updated September 2026, drawing on World Bank, INFORM Risk Index and ND-GAIN Country Index.
