Variability of Climatic Parameters in Tiefora, Burkina Faso: Scientific Aspects and Farmers' Perceptions

Summary/Abstract: The evolution of climatic parameters is of major importance for the populations of the Sahel, and in particular Burkina Faso, whose agricultural production is predominantly rain-fed. The aim of this study is to analyze the variation in climatic parameters in the rural commune of Tiéfora in Burkina Faso. Climatic data from 1991-2020 were collected from the National Meteorological Agency (ANAM). In addition, individual questionnaire surveys were carried out among 100 local people. The results show that from 1991 to 2020, 19 out of 30 years had rainfall in excess of 1000 mm. The area experienced 16 years of rainfall surpluses, compared with 14 years of rainfall deficits. In terms of temperature, the annual average rose from 27.08°C to 28.43°C from 1991 to 2020, a difference of 1.35°C. This indicates a rise in temperature. Other climatic parameters (wind, humidity and ETP) have also varied in the area, with an increase. The people of Tiéfora perceive this rise in temperature and a fall in rainfall.
