In Niger, the vulnerability of rural households is increasingly accentuated insofar as they depend mainly on rain-fed agriculture, which has been subject for several decades to the devastating effects of climate change. Thus, the issue of the sustainability of agriculture in development policy should not be overlooked. In this sense, this study is focused on assessing the economic sustainability of 234 millet and Karma cowpea farms in a context of climate change. To assess the performance of this dimension, 11 indicators divided into 4 components of the IDEA (Indicator of Sustainability of Agricultural Operations) version 4 method have been defined. The formulas for calculating scores by indicator, by component and then by dimension were developed based on the method developed in the HEA (Household Economic Approach) Extensive approach. Overall, the score for economic sustainability is 2.15, reflecting the low sustainability of these farms. The results show that two indicators were sustainable. These are aid sensitivity and economic transmissibility with respective scores of 3.47 and 2.93. To have an economically viable agriculture, the rest of the indicators should be optimized in order to increase the score of the economic sustainability of the municipality of Karma.
Author Keywords: economic sustainability, production system, millet, cowpea, climate change, Karma.

In Niger, the vulnerability of rural households is increasingly accentuated insofar as they depend mainly on rain-fed agriculture, which has been subject for several decades to the devastating effects of climate change. Thus, the issue of the sustainability of agriculture in development policy should not be overlooked.

Abstract: (french)
Au Niger, la vulnérabilité des ménages ruraux s’accentue de plus en plus dans la mesure où ils dépendent principalement de l’agriculture pluviale sujette depuis quelques décennies aux effets dévastateurs du changement climatique. Ainsi, l’enjeu que représente la durabilité de l’agriculture dans la politique du développement n’est pas à négliger. En ce sens, cette étude est focalisée sur l’évaluation de la durabilité économique de 234 exploitations agricoles du mil et niébé de Karma dans un contexte de changement climatique. Pour évaluer la performance de cette dimension, 11 indicateurs répartis dans 4 composantes de la méthode IDEA (Indicateur de Durabilité des Exploitations Agricoles) version 4 ont été définis. Les formules de calcul des scores par indicateur, par composante puis par dimension ont été élaborées en s’inspirant de la méthode développée dans l’approche HEA (Household Economic Approch) Extensive. Dans l’ensemble, le score de la durabilité économique est de 2,15 traduisant ainsi une faible durabilité de ces exploitations agricoles. Les résultats montrent que deux indicateurs ont été durables. Il s’agit de la sensibilité aux aides et de la transmissibilité économique avec des scores respectifs de 3,47 et 2,93. Pour avoir une agriculture économiquement viable, il faudrait optimiser le reste des indicateurs en vue d’augmenter le score de la durabilité économique de la commune de Karma.
