The research conducted in San Diego, municipality of Samana - Caldas, is oriented to claim public management from community management as an alternative to rural development. The model implemented since the decade of the 50´s, as well as has exacerbated the rural problems --- structure of land holding, bipartisan violence against the rural population, absence government---, has generated other problems with direct impacts in the township, associated with the implementation of the green revolution, the worsening of armed conflict between anti-state and para-state groups for territorial control, the re-structuring of State from the logic of private management, the clientelist political culture since the national context to the municipal, as well as new supranational forms of geopolitical control. In this context, community organizations of San Diego should participate actively in the public management, as a process oriented to ecological and cultural welfare of the territory with the participation of community agents in seek of local autodetermination; the real commitment by government agents with the general interest; and the involvement of academics, NGO´s and privates in revitalization of creative and productive forces of the territory. In this sense, starting from the environmental as a social right and four theoretical and methodological references--- Rural territory”, “situation”, “environmental problematic”, “strategic situation planning----, was made a situational diagnostic about environmental, natural, cultural and humane dimensions, as well as public management in the context of rural development in San Diego. As a result of diagnostic were identified environmental problems that shape the environmental problematic territorial. Subsequently, the assessment was made about public management from as the study of the problematic, which allowed selecting of some focuses of action for the planning process with community organizations that involved in the public management of the township. Finally, was arranged a Community Action Plan for the management of environmental issues that shape environmental problematic, where these were strained socially, as an administrative instrument that is establish in the strategy of public management from the community management as a local alternative for rural development in San Diego. In this way, management proposals from the Environmental Management in the real Colombia, with its social and armed conflict in rural territories, must be the result of investigative processes which show territorial environmental problems, from theoretical and methodological pertinent references.
