Growing population is a challenge for developing countries. They must resort to quality agriculture in order to meet the nutritional needs of this population. In Benin, agriculture occupies a prominent place in the socio-economic life of the population. The objective of this study is to identify from a multi-criteria approach combined with GIS, the specific areas for the cultivation of various cereals, tubers and other food crops and market gardening in order to contribute to the improvement of yields in Hills. The methodology used is based on GIS techniques coupled with multi-criteria analysis methods from data on the physico-chemical components of the soil, agricultural statistics and socio-economic data obtained in the field. The results obtained show that the hills department has a good aptitude for soybean crops and market gardening but moderately suitable in the communes of Dassa-Zoumè and Savè. In general, the department of Collines is suitable for most crops practiced in Benin. This is partly due to the knowledge that producers have of the quality of their soil, often assessed through the level of yield of the previous one.

Abstract
Growing population is a challenge for developing countries. They must resort to quality agriculture in order to meet the nutritional needs of this population. In Benin, agriculture occupies a prominent place in the socio-economic life of the population. The objective of this study is to identify from a multi-criteria approach combined with GIS, the specific areas for the cultivation of various cereals, tubers and other food crops and market gardening in order to contribute to the improvement of yields in Hills. The methodology used is based on GIS techniques coupled with multi-criteria analysis methods from data on the physico-chemical components of the soil, agricultural statistics and socio-economic data obtained in the field. The results obtained show that the hills department has a good aptitude for soybean crops and market gardening but moderately suitable in the communes of Dassa-Zoumè and Savè. In general, the department of Collines is suitable for most crops practiced in Benin. This is partly due to the knowledge that producers have of the quality of their soil, often assessed through the level of yield of the previous one.

Abstract: (french)
L’augmentation croissante de la population constitue un défi pour les pays en voie de développement. Ils doivent avoir recours à une agriculture de qualité afin de satisfaire les besoins nutritionnels de cette population. Au Bénin, l’agriculture occupe une place prépondérante dans la vie socioéconomique des populations. L’objectif de cette étude est d’identifier à partir d’une approche multicritère combinée au SIG, les zones spécifiques à la culture des diverses céréales, les tubercules et autres cultures vivrières et maraîchères afin de contribuer à l’amélioration des rendements dans des Collines. La méthodologie utilisée est basée sur les techniques des SIG couplées avec les méthodes d’analyse multicritère à partir des données des composantes physico-chimiques du sol, des statitiques agricoles et des données socioéconomiques obtenus sur le terrain. Les résultats obtenus montrent que le département des collines a une bonne aptitude pour les cultures de soja et le maraîchage mais moyennement apte dans les communes de Dassa-Zoumè et Savè. De façon générale que le département des Collines est apte pour la plupart des cultures pratiquées au Bénin. Ceci est en partie, dû aux connaissances que les producteurs ont de la qualité de leur sol, souvent apprécié à travers le niveau de rendement de la précédente.
