Family farms in Moundou are facing the effects of climate variability. Due to increased rainfall variability and rising temperatures marked by an evolving trend, farm household incomes are increasingly affected. The objective of this study is to assess the effects of climate variability on the incomes of farm managers in order to contribute to a better understanding of the effects of climate variability on family farming. The study uses the Ricardian model to analyze the effects of rainfall and temperature variations and socioeconomic determinants on the incomes of farm managers. Data were collected from 105 farm managers distributed according to their wealth level. The results showed that an increase of 1 mm in average rainfall will lead to an increase of 1.2% FCFA/hectare of agricultural income, i.e., a gain of 1633 FCFA/hectare. On the other hand, a 1% increase in temperature will result in a 5.65% decrease in agricultural income, i.e., a loss of 7,692 FCFA/hectare on average. The analysis of the projected effects of climate variability through scenarios of increases in average temperatures of 1°C and 1.5°C and average annual decreases in rainfall of 5% and 8% showed that income losses will be accentuated. Thus, this situation calls for reflection on appropriate adaptation strategies to mitigate the adverse effects on family farming while taking into account the diversification of family farms.

Abstract: (french)
Les exploitations agricoles familiales à Moundou sont confrontées aux effets des variabilités climatiques. En raison de variabilité des pluies accrue et d’augmentation des températures marquée par une tendance évolutive, les revenus des ménages agricoles sont de plus en plus affectés. L’objectif de cette étude est d’évaluer les effets de la variabilité climatique sur les revenus des chefs d’exploitation agricole afin de contribuer à une meilleure connaissance des effets de la variabilité climatique sur l’agriculture familiale. L’étude est basée sur le modèle Ricardien pour analyser les effets des variations des précipitations et des températures et des déterminants socioéconomiques sur les revenus des catégories de chefs d’exploitation agricole. Les données sont collectées auprès de 105 chefs d’exploitants agricoles repartis, selon leur niveau de richesse. Les résultats ont montré que l’augmentation de 1 mm en moyenne de la précipitation va entrainer une augmentation de 1,2% FCFA/hectare de revenu agricole, soit un gain de 1633 FCFA/hectare. Tandis que, l’augmentation de 1% de températures entrainera une baisse de revenu agricole de 5,65%, soit une perte de 7.692 FCFA/hectare en moyenne. L’analyse de la projection des effets des variabilités climatiques à travers des scenarios des hausses des températures moyennes de 1°C et de 1,5°C et des baisses moyennes annuelles des précipitations de 5% et de 8% a montré que les pertes de revenus seront accentuées. Ainsi, cette situation pousse à réfléchir sur les stratégies d’adaptation appropriées pour atténuer les effets néfastes sur l’agriculture familiale tout en tenant compte de la diversification des exploitations agricoles familiales.
