Brazil has the largest mangrove areas in the American continent, constituting an important economic resource used by coastal populations in the tropics due to its great diversity, carbon richness and functionality.
Objective: To present the critical areas of mangroves and the degradation of the geo-economic mosaic.
Theoretical framework: the Pigou-Coase principle was focused in order to understand the restoration structure in mangrove areas, through the polluter-pays principle, focusing on the mangrove conditions in the estuary of the Itapessoca river, Goiana-PE, Brazil, which suffers a high process of environmental decharacterization.
Method: Case study based on the reference of R. Yin, with the employment of bibliometrics’ tools (WoS) and mapping mosaic using QGis and SIRGAS software.
Results and Conclusions: In the Itapessoca region it can be observed that there is no rigor of use of risk or preserved area, since the principles are the foundation of the rules the legislation is not comprehensive, and there is presence of predatory treatment.
Research Impact: Case studies constitute an important type of research as it anchors what is most impactful to local reality vis a vis theoretical platform.
Originality: The PPP model applied to the mangrove of Itapessoca-Pernambuco-Brazil.
