The peripheral area of Bafoussam is part of the production basin of the region of West Cameroon which is under the influence of climate change.

This study intends to show the impact of climate variability on crops production as well as the producers' adaptation strategies in the peri-urban area of Bafoussam. Statistical analysis has been applied to the climatological data (precipitation and temperature) of the period 1999-2015 as well as those of agricultural especially some specific crops. The annual change in rainfall over the study period shows a deficit trend during seven years while four years have a rainfall totals approaching the inter-annual average (1725 mm) and six years exceeding the rainfall mean value. In addition, the temperature growth rate is -0.05 ℃ while the precipitation rate is 10.29 mm from 1999 to 2015. All these climatic modifications cause many damages such as the burning of plant due to the heat, the development of pests (attack of caterpillars) and the appearance of diseases (bacterial wilt) which have a direct impact on yields. In response to this climatic situation, farmers have developed several adaptation strategies. Irrigation is the main practice constructed from rivers to reduce the impacts of dry days on crops. During the rainy season, areas having a deficit of water are supply by a retention of precipitation through bins of water for crops.

The peripheral area of Bafoussam is part of the production basin of the region of West Cameroon which is under the influence of climate change. The last decades have been characterized by climatic disturbances whose effects remain visible on the agricultural production. This study intends to show the impact of climate variability on crops production as well as the producers' adaptation strategies in the peri-urban area of Bafoussam. Statistical analysis has been applied to the climatological data (precipitation and temperature) of the period 1999-2015 as well as those of agricultural especially some specific crops. The annual change in rainfall over the study period shows a deficit trend during seven years while four years have a rainfall totals approaching the inter-annual average (1725 mm) and six years exceeding the rainfall mean value. In addition, the temperature growth rate is -0.05 ℃ while the precipitation rate is 10.29 mm from 1999 to 2015.

Abstract: (french)
Le périurbain de la ville de Bafoussam fait partie du bassin de production de la région de l’Ouest Cameroun qui est sous l’influence de la variation climatique. Les dernières décennies ont été caractérisées par des perturbations climatiques dont les effets restent perceptibles sur la production agricole. Il s’agit dans cette étude de montrer l’incidence de la variabilité climatique sur les productions maraîchères ainsi que les stratégies d’adaptation des producteurs dans le périurbain de Bafoussam. Des analyses statistiques ont été portées sur les données climatologiques (précipitations et températures) de la période 1999-2015 ainsi que sur les données de productions de quelques spéculations agricoles. L’évolution annuelle de la pluviométrie sur la période d’étude montre une tendance de la baisse marquée par sept années déficitaires, quatre années dont les cumuls pluviométriques sont proches de la moyenne interannuelle (1725 mm) et six années excédentaires. De plus, le taux de croissance des températures est de -0.05℃ tandis celui des précipitations est de 10.29 mm de 1999 à 2015. Toutes ces modifications climatiques ont pour conséquences, des brûlures des plantes, le développement de parasites (invasion des chenilles) et l’apparition des maladies (flétrissement bactérien) qui ont des effets directs sur les rendements. En réponse à cette situation climatique, les paysans ont développé plusieurs stratégies d’adaptation. Pour résister aux aléas climatiques auxquels sont soumises les cultures de saison sèche, l’irrigation manuelle ou par des canaux à partir des rivières sont construits. D’autres par contre créent en saison de pluies des bacs de terre pour la rétention de l’eau de pluies afin d’arroser les cultures en cas de déficit hydrique.
