This article focuses on the impact of climate change on millet production in the Madaoua department, Niger. Niger is a country vulnerable to the effects of climate change due to its high climatic variability and its dependence on rain-fed agriculture. Millet is a crucial cereal grown in the region, accounting for a significant share of the country's cultivated area and cereal production. The objective of this study is to assess the impact of climatic parameters, such as temperature and rainfall, on millet yield. Production data and meteorological data were used to analyze rainfall trends and anomalies, as well as the variation in maximum temperature over a 30-year period (1992-2022). The results show a slight upward trend in mean annual rainfall, although year-to-year variability is high. Dry and wet years do not necessarily follow a linear trend. Dry years are associated with below-average precipitation, while wet years have above-average precipitation. The maximum temperature showed a steady increase over the years, with some fluctuations. In 2021, the average maximum temperature was 36.5°C. This increase in temperature may have a negative impact on millet production and food security in the region. The study also uses regression analysis to examine the relationship between millet yield and climatic parameters. The results of this analysis can help to better understand the effects of climate change on agriculture and to formulate recommendations for effective adaptation in order to maintain agricultural productivity and sustainability in the department of Madaoua.
