This agrarian diagnosis was made following the first diagnosis of Chabane in 2013 in North Grande-Terre, in response to a request from INRA and CANGT in order to meet the development challenges of Guadeloupe. This work presents a model of the diversity of the farmers of North Grande-Terre as product of the History and the Biophysical Environment, which reveals and explains the numerous differences of practices, but also of technical and economic results of the agricultural exploitations. The North Grande-Terre is a vast limestone plateau with deep Vertisol soils in the plain and stony skeletal soils on the uplands. It is the first pool sugar cane of Guadeloupe. The plain area, long inhabited by native Indians who cultivated cassava and yam was gradually artificialized in favor of the monoculture of sugar cane, product of colonization. After the abolition of slavery, diversification crops developed a little in the plains and the uplands as well as livestock systems. But it was rather with the arrival of irrigation in the 90s that these systems intensified and allowed the arrival of banana and melon growing systems in North Grande-Terre. However, sugar cane remains the dominant culture of the region. But this culture no longer produces wealth, it is profitable only with subsidies. Imposed by the GFA land system, this crop has declined significantly in recent years in favor of vegetable crops/ food crops and livestock. Capitalist systems with large surfaces in cane are currently found on the areas not affected by the land reform at the heart of the old estate, directly claiming the factories; multi-skilled farmers; family systems focusing on cane cultivation or not, while maximizing their value-added per unit area through more profitable crops; organic systems that want to optimize sales and offer quality products. With the "Lizin Santral" project, which promotes small-scale family farming and diversification, these small farmers, considered as little supported and excluded, see a glimmer of hope. But this supply by farmers is a little risky in this current context marked by the land problem, lack of access to water, lack of technical support, and the various thefts.
