ANALYZING ECOSYSTEM SERVICES VALUATION METHODOLOGIES: A SYSTEMATIC REVIEW

One of the environmental challenges is the preservation and maintenance of the environment. In view of this, the gains are valid and are considered as auxiliary mechanisms to the tangible goods and services promoted by the ecosystems, which can be considered efficient for the control of tangible goods and services. Therefore, the objective of this article is to systematically review which methodologies have been used to value ecosystem services and theirs. This applies specifically: to studies that value the eco-services studied, using only practical methods studied. For that, a systematic review was elaborated, using as databases: Web of Science and Scopus, illustration of gray literature. The results of the analysis found the valuation of ecosystem services using methods still used, in addition, general studies are still incipient more than a statistical methodology. It can be seen that the complexity of giving value to services depends on a set of measurements, due to its complexity. From the elaboration of this study, it is expected that the readers can succinctly know the existing methodologies on the subject, still encourage creativity for the elaboration of new methodologies of monetary valuation. Finally, that this theoretical study contributes to enhance the importance of the subject, extending to the public power as a motivation for the emergence of public policies on the subject.
