Climate–land interaction over West Africa has often been assessed using climate simulations, although the model-based approach suffers from the limitations of climate models for the region. In this paper, an alternative method based on the analysis of historical land cover data and standardized climatic indices is used to investigate climate–land interactions, in order to establish climatic conditions and their corresponding land cover area changes. The annual variation in land cover area changes and climatic changes are first estimated separately and then linked using various spatiotemporal scales. The results show that incidences of land cover change result from abrupt changes in climatic conditions. Interannual changes of −1.0–1.0 °C, 0–1.5 °C, and −0.5–0.5 °C, and up to ±50 mm changes in precipitation and climatic water balance, lead to 45,039–52,133 km$^2$, 20,935–22,127 km$^2$, and approximately 32,000 km$^2$ changes, respectively, while a ±0.5 °C and ±20 mm change represents normal climate conditions with changes below 20,000 km$^2$. Conversely, conversions of cropland, forest, grassland, and shrubland are the main land cover change types affecting the climate. ... mehr
