Abstract

In this work, we examined the effects of albedo and solar flux on climate parameters in Burkina Faso (1984-2022). We found that albedo amplitudes in Dori region are higher than those in Ouagadougou, and those in Ouagadougou are higher than those in Bobo Dioulasso. We also observed a continuous decrease in albedo, leading to an increase in temperature, humidity, and precipitation. These climatic conditions may increase the risks of prolonged droughts and floods. This drop in albedo is linked to solar activity, growing urbanization, deforestation and global climate change. Low solar activity and solar high speed flows caused by corotative interactions regions lead to heavy precipitation. The use of reflective construction materials, i.e. high albedo, in urban infrastructure and stopping the transformation of forests into cultivable land can contribute to mitigating the diminution in albedo and consequently global warming.
