This work focused on identify and spatialize the area of direct hydrological influence of mangroves, its landscape dynamics and the socioeconomic aspects of the Environmental Protection Area (EPA) of Barra do Rio Mamanguape in the period of fifteen years (2001-2016). With this objective, this work identified the direct hydrological influence area (HIA) in the mangroves of this EPA, as well as the main drainage lines that form the drainage network of its mangrove. Analyzed some morphometric parameters and Landscape Ecology concepts of the environmental fragilities of the identified basins. Analyzed the dynamics of land use and occupation on a temporal scale through techniques and metrics of landscape analysis, and analyzed the socioeconomic dynamics on a 10-year time scale (censuses 2000 and 2010). After the research, it was verified that, among the analyzed basins, the Mamanguape basin has morphometric parameters and land uses that threaten the homeorres of the natural ecosystems. A significant reduction (7,529 ha) of the Natural Ecosystems during the period was also observed. The lack of planning, supervision, opportunities to earn income for the communities, and social risk situations contributed to this. There was also a strong dynamic in the socioeconomic parameters analyzed in all six counties inserted in the HIA. The Federal Government funds cut for the ICMBio, which manages the UC influences in the preventive actions and of environmental education. There are shortcomings in the elaboration and implementation of public policies that aim for environmental conservation and improvement of the quality of life of the inhabitants by the responsible agencies. The lack of communication between the different spheres of public administration compromises the actions of inspection, prevention and punishment of environmental infractions. The deprivation of substantive liberties negatively influences social-environmental relations through the extractive use of unplanned natural resources. There is a need for joint actions between organized civil society and government in all spheres in order to strengthen sustainable local development with participatory management. The region has natural and cultural wealth that must be preserved, including indigenous culture. The use of different geotechnical techniques, added to the knowledge of Landscape Ecology, has proved relevant for a better understanding of the dynamics of this landscape. Solid information for planning of negative impacts mitigation and conservation of natural resources and supervision by responsible agencies were generated. Taking into account the socioeconomic dynamics through the evaluation of census data carried out by the IBGE, it is conclusive that the fragilities in the different communities were identified. Thus, important data were generated for the State and other institutions in the search for solutions to socioeconomic problems that interfere directly in the conservation of natural resources.
