Analysis of Climate Variability and Relation to Vegetation in Garamba National Park from 1990-2020

A significant inverse correlation between temperature and precipitation (r = -0.876, p < 0.00001) was identified in Garamba National Park over three decades, with precipitation showing a positive association with vegetation indices (NDVI: r = 0.496; EVI: r = 0.496). The study analyzed climate-vegetation relationships using non-parametric tests and statistical analyses, revealing that increased rainfall corresponds to higher vegetation density. This finding underscores the sensitivity of Garamba's unique savanna-forest mosaic ecosystem to climatic shifts, critical for its conservation as a UNESCO-listed site.
