Enhancing Resilience to Climate Change to Support Food Security in Vulnerable Communities Across Central Africa

Climate change remains to cripple food security across Central Africa, where a large proportion of the population depends on rain-fed agriculture survival. This study evaluated the environmental, economic, energy and agricultural factors shaping climate resilience and food security in vulnerable communities, using secondary time-series data spanning 2000 to 2025 across 14 variables, including 2 climate resilience variables (mean annual temperature and annual rainfall). Descriptive statistics, pre- and post-2013 period comparisons, Pearson correlation analysis, detrended correlation and multiple regression analysis were applied. Findings show that undernourishment averaged 30% over the period, with persistently low cereal yields and minimal electricity access. Rising mean annual temperature (r = -0.610, p = 0.002) was significantly correlated with declining cereal yields (r = -0.880, p < 0.001). In the multiple regression model (R² = 0.907), electricity access and GDP per capita are the two strongest independent predictors of undernourishment, while political stability remained a significant bivariate correlate. These results suggest that energy infrastructure and governance, above agricultural land use or GDP, are central to food security outcomes defining how resilience-building efforts should be concentrated.
