Within the framework of the investigation environmental management analysis that allows to strengthen political-administrative decentralization in the municipality of Encarnaci?n, the next question is posted: are municipal strategies adequate to environmental theories? In this regard, the specific objective is to evaluate the situation of environmental management of Encarnaci?n Municipality from the perspective on urban ecosystem. The investigation was developed in the analytical and propositive phases with documentation review of primary and secondary sources; the indicators of the urban ecosystem and the strategic axes of the sustainable development plan were used and a relation between both was established with a numerical assessment based on the Encarnaci?n municipality diagnosis. The results indicate that strategies are appropriate, but an average of 2.14 in an evaluation from 1 to 5 was found, which points out that there is much to be done in terms of management. Executed actions in the municipality are carried out in a framework of political-administrative decentralization with its own management, which is a strength. Main proposals for strengthening are: the adoption by ordinance of the Plan of Sustainable Development and a later implementation of it.
