River basins are key geographic units in water resource management, and river basin problems throughout the world are mainly due to anthropogenic pressure related to land use, domestic effluent disposal, agricultural and industrial effluents, soil erosion, Deforestation, changes in the structure of the biotic communities, among others (GIORDANO et al., 2004, TANAKA, 2008 and DELINOM, 2008). The object of study of this research is the Mocajuba River Basin - BHRM, located in three municipalities of northeast São Paulo: São João da Ponta, Terra Alta and Curuçá, in the demarcation of its limits are contained two Conservation Units. In the western portion the São João da Ponta Marine Stratigraphic Reserve and in the eastern portion the Marine Extraction Reserve Mãe Grande de Curuçá. In general, this river basin has been undergoing degradation as a consequence of lack of basic sanitation, territorial occupation in inappropriate places, deforestation of mangrove areas and other areas for the expansion of agriculture, degradation of Permanent Protected Areas (PPAs), fires, Sedimentation of water bodies (ICMBIO, (2010); PANTOJA, (2012); RODRIGUES & FRANÇA, (2014); TELES, (2016)). And for lack of a management plan, it can manage its various uses. On the other hand, the Mocajuba river has a high importance for the communities that live in its surroundings, since they need their resources for their survival, given that their economic, social and cultural activities are developed in these areas. Therefore, the conservation of natural resources and the sustainable management of BHRM are considered a strategic issue from the environmental point of view, as social and economic for these populations. In this sense, the aim of this research is to analyze the Mocajuba river basin, based on the model PEIR - Pressure-State-Impact-Response as an instrument to evaluate the conditions of use and management of this natural resource, with the aim of contributing to its management . This matrix (PEIR) is structured from the identification of causal anthropic activities or sources of pressures and impacts. These activities, based on socioeconomic, on natural resources produce pressures and impacts that alter the state of its components, in order to assist in mitigation, it is proposed by society or by the public power actions (answers) that can solve or soften them. The research is considered as descriptive, exploratory and in terms of the means evaluated as a case study resulting from the process of consulting the various social and institutional actors directly involved with the environmental problems of the basin. The developed methodological model constitutes an original tool for the area of environmental management, specifically, with respect to activities that impact the environment. Regarding the variables of the PEIR model, these were analyzed based on the absence or presence of the same to the sustainability, taking into account the dimension analyzed.
