Drought is a recurrent phenomenon in the Sudano–Sahelian region of Cameroon. However, it has received very little attention, especially, on its impacts on the growing season of crops. To fill this gap, this study assessed the drought hazard using standardized precipitation index at a 3-month scale, and phenology of the main crops in 19 rainfall stations in the Sudano–Sahelian region of Cameroon for the period 1980–2012. The trend of drought was studied using the Mann-Kendall technique. The agricultural drought hazard was quantified based on its frequency and intensity. Results show that there is a significant trend toward a more humid crop-growing period in the northern and southeastern parts of the study area, but significant dry trends during the maize and peanut growing periods in the southwestern part of the study area. Drought occurrence rates are 7.09, 4.22, and 3.17% for the moderate, severe, and extreme, respectively. Areas featuring high and very high agricultural drought hazards are distributed in the far north, central, and the southeastern parts of the study domain. Furthermore, the Sahelian and Sudanian climatic conditions were found to be very high agricultural drought hazard zones, especially, where the maize and peanut grain crops are concerned. However, significant dry trends and very high agricultural drought hazard zones during the maize and peanut growing periods are catastrophic for agriculture and, therefore, food security.

在喀麦隆的苏达诺–萨赫勒地区，干旱是经常性的现象。但是，它很少受到关注，特别是对作物生长季节的影响。为了填补这一空白，本研究使用标准化的降水指数在3个月内评估了干旱的危害，并评估了1980-2012年喀麦隆苏达诺-萨赫勒地区19个降雨站的主要农作物物候。使用Mann-Kendall技术研究了干旱趋势。根据农业干旱的发生频率和强度来量化。结果表明，在研究区域的北部和东南部，有一个明显的趋向于更湿润的农作物生长时期，但是在研究区域的西南部，在玉米和花生的生长期则存在着明显的干旱趋势。中度，重度和极度干旱发生率分别为7.09、4.22和3.17％。农业干旱危险性很高和非常高的区域分布在研究区域的最北部，中部和东南部。此外，发现萨赫勒和苏丹的气候条件是非常高的农业干旱危险区，特别是在涉及玉米和花生谷物作物的地区。但是，在玉米和花生生育期，明显的干旱趋势和极高的农业干旱危险区对农业以及因此对粮食安全而言都是灾难性的。和研究领域的东南部。此外，发现萨赫勒和苏丹的气候条件是非常高的农业干旱危险区，特别是在涉及玉米和花生谷物作物的地区。但是，在玉米和花生生育期，明显的干旱趋势和极高的农业干旱危险区对农业以及因此对粮食安全而言都是灾难性的。和研究领域的东南部。此外，发现萨赫勒和苏丹的气候条件是非常高的农业干旱危险区，特别是在涉及玉米和花生谷物作物的地区。但是，在玉米和花生生育期，明显的干旱趋势和极高的农业干旱危险区对农业以及因此对粮食安全而言都是灾难性的。
