São Caetano de Odivelas is a municipality in the Amazon coastal zone, located in the
Microregion of Salgado, in the Northeast of Pará, with the coastline cut by wide recesses
or the coast of “rias”, composing a dynamic environment, under which a vast mangrove
forest. Recently, the Mocapajuba Extractive Reserve was created in the municipality in
2014. Therefore, this research aimed to evaluate the mangrove areas from driving force,
pressure, state, impact and response indicators (PSIR), to provide support to the
management of the Conservation Unit. The method chosen was the use of socio environmental indicators, combined with the DPSIR methodology created by the United
Nations Environment Program - UNEP, and updated by the Organization for Economic
Cooperation and Development - OECD. It was necessary to carry out a systematic review
of the literature and conducting on-site visits, in order to assist in monitoring the state and
in the analysis of the pressures found in the study area, parallel to this, a classification of
the different types of land use was made. in order to identify the anthropic causal activities
or sources of pressures and impacts. And the responses obtained through the research of
programs and projects at the federal and municipal levels that can solve or mitigate
impactful actions. The methodology proved to be satisfactory, as it allowed to infer about
the following indicators: Pressure (P) urban expansion, tourist intensity and the absence
of sewage treatment; State (E) legally protected area, with high environmental relevance
and ecological functions and "in natura" sewage discharge in the Mojuim River; Impact
(I), the most significant ones were applied to the model according to the weighting
performed. these being: mangrove deforestation, overfishing due to tourism and the
effects of waste disposal in inappropriate areas, on the quality of life of the population
and the natural environment. The analysis of the answers (R) revealed the Mocapajuba
Marine Extractive Reserve (RESEX), since from it it is possible to obtain control over
land use, under the domain of the Chico Mendes Institute for Biodiversity Conservation
(ICMBio) (federal sphere) ; the guidelines of the Brazilian Forest Code in Areas of
Permanent Preservation - APP (MMA), in contrast, the municipal government through
investments and public expenses with the purpose of promoting the protection and
management of natural resources, such as the promotion of environmental education.
Thus, the need for an effective inspection and long-term projects for environmental
management, which reconciles use with environmental protection, stands out. Thereby,
this work is configured as an important tool, in order to provide subsidies for the
elaboration of environmental planning projects and management policies, and actions
based on the protection of the mangrove ecosystems.
