The Evolution of the Onset and the Cessation of the Rainy Season in Burkina Faso: A Comparative Study of Two Climatic Conditions

Abstract

Rainfall is a key variable in agricultural production. In Burkina Faso, it contributes to cereal production, which in turn contributes to food security. Understanding these characteristics is essential for a successful cropping season. The main objective of the study is to analyze changes in the rainy season between 1991 and 2020. To achieve this, the methodology is based on the collection of monthly rainfall data between 1991 and 2020. The data collected was processed by calculating the onset and cessation of the rainy season, as well as the dry periods of the rainy season. The study shows that the onset of the rainy season varies greatly from one decade to the next (1991-2000, 2001-2010, 2011-2020). Conversely, cessation of the rainy season varies very little. In addition, the onset of the rainy season is accompanied by dry periods, which are both increasing and decreasing at the Boromo station. On the other hand, at the Gaoua station, the onset and cessation of the rainy season are followed by dry periods, which are decreasing. It is therefore important that political decision-makers take steps to support farmers in the Boucle du Mouhoun region with seeds that adapt to the new agricultural calendars.
