In Latin America, the socioeconomic development models are based, generally, on the exploitation of natural resources with a poorly planned vision. Promote the environmental fragility. The producer typology, in Mexico, is composed of the ejidatarios, comuneros and the intermediate or in transition individuals, and the agro industrials. The changes of agro cultural habits cannot be achieved by decree, without losing sight of the fact that public policies favor the globalized agricultural market, not the interim. The ability to call for the participative planning with a comprehensive management approach of watersheds, presents difficulty for its instrumentation, requiring planning instruments more aimed for the different degrees of environmental sensitivity in specific areas of the whole of the river basin. The inclusion of the social sector in the decision-making. For that purpose, it is raised the research question, What crops can be selected for the agro productive diversification in the Tolapan Coatepec State of Veracruz micro-watershed, on the basis of the particular conditions that are agro-ecological, climatic, soils and physiographic with technical, economic and social feasibilities, which can be integrated to a territorial model for the decision-making, the objective was to develop a support system, for decision-making in the production diversification for crops with technical, economic and social potentials to transit towards a more sustainable benefit. The subsystems are integrated by properties in the individual and in its articulation, (approach, analysis, diagnosis, prognosis, understanding). Operated through a territorial information system with free software and hardware. The statistical design combines quantitative and qualitative researches. We identified 27 crops with productive, technical and economic feasibility potential. This model is complementary with other methodologies, also flexible, and it can be adapted to different scales and different conditions of information availability, therefore, it is suitable for the Local, Regional and National managements.
