Climate Trends and Changes in Biodiversity in the Comoé National Park (North-East Côte d'Ivoire)

Abstract

The Comoé National Park, with a surface area of 1,149,450 hectares, stands out for its exceptional biodiversity. However, in the context of current climate change, marked by the gradual degradation of natural resources, it is crucial to understand how this changing climate is influencing this biodiversity. The study therefore aims to show the impact of current climatic conditions on changes in biodiversity within Comoé National Park. The methodology adopted is based on a combined analysis of climatic data, vegetation indices and observations of animal species in the park, using statistical and geomatic approaches. A diachronic analysis was used to study the relationship between climate dynamics and changes in recent plant and animal species, using correlation tests. The results reveal a significant decrease in rainfall and humidity, as well as an increase in temperature. Analysis of Thom's discomfort index and the improved vegetation index indicates a deterioration in conditions for biodiversity to flourish, accentuated by the climatic irregularities observed.
