Abstract :

The use of climate finance has become one of the most significant means of combating climate change at the international level, but its conversion into tangible impacts has been extremely uneven in the Global South. The aim of this paper is to examine how the three largest emerging economies, South Africa, Nigeria, and India, implement climate finance and whether the national policy framework is effective in translating finance into tangible impacts. The fivelens approach used for the examination includes policy coherence, implementation, evidence of impact, economic impact, and structural obstacles. The question to be examined is whether the funds work. Based on the results from the analysis, it becomes evident that while all three countries have indeed taken real efforts to align themselves with global conventions like the Paris Agreement and the UNFCCC, there are implementation gaps when it comes to ground realities. There have been positive developments on the part of South Africa and its REIPPPP and on the part of India and its NAPCC. However, both initiatives still face serious issues related to fragmented governance and lack of financing resources. Nigeria, even though its policy framework has become quite ambitious, suffers from poor institutional coordination, high administrative costs and persistent under-financing of adaptation activities. It is evident that the key determining factor here is not finance but quality of institutions and coherent implementation practices.

Abstract :

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 using SPSS. 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.
