Socioeconomic and productive marine and estuarine fishery activity potential index

Abstract

Considering the need for increased productivity, consequently providing a safe source of quality food and economic sustenance for numerous families, fishing in the State of Rio de Janeiro is configured in an important way, and with a primarily artisanal and professional nature of small bearing. In addition to the fundamental aspect of human subsistence, fishing is an important economic activity, generating several other businesses and income for other economic sectors, such as transport, storage, processing and sale of products, construction and repair of vessels, and construction of artifacts and utensils, among others. Thus, the study of potentialities and vulnerabilities involving the strengths and weaknesses of the coastal region of Rio de Janeiro will assist in actions in favor of a broad development of activity in the coastal municipalities. For this, the analytic hierarchy process was used, a multicriteria analysis method, to construct hierarchies of these municipalities in terms of potential development, and thus the analysis of the environment was performed using a matrix to analyze the scenarios. The results point out that due to the importance accorded by the interviewees to the economic sub-index, the municipality of Angra dos Reis stood out in the order of priority of defining the municipality with the highest socioeconomic and productive potentiality index for fishing activity, presenting quantitative data related to sub-indices of greater importance than the other municipalities. However, when the analysis for each subscript was carried out separately, Angra dos Reis has the lowest classification for vulnerability to environmental and social issues.
