Abstract:
Studies on rainfall fluctuations have established periods of drought and humidity in West Africa since the 1970s. Guinea, which is one of the countries in this part of Africa, is subject to changes that lead to episodic floods and droughts. In recent years, the Siguiri area, in the north-east of the country, has suffered from climatic fluctuations that have affected the availability of groundwater resources. The methods used to verify this natural reality are diverse and consistent with those used for such studies. Climatic studies carried out in the Siguiri prefecture show that there were major breaks in the regularity of rainfall patterns in the 1980s. In the study area, dry and wet periods alternate, exposing the prefecture to rainfall deficit conditions that contribute to global warming.
