Mapeamento de Conflitos de Uso e Ocupação no Complexo Estuarino de Paranaguá e Plataforma Rasa: Subsídios para o Planejamento Espacial Marinho

Abstract

The preference for housing in coastal environments has become a human strategy due to several factors; as biodiversity wealth, geographic strategy, or abundance of f ishing resources. The coastal and estuarine environment is a place of multiple uses for industrial, commercial, housing, port, and ecologically essential purposes. An effective Marine Spatial Planning (MSP) is essential to establish a rational organization of the use of the marine space and the interactions between its uses, in order to balance the demands of development with the need to protect marine ecosystems, as well as to achieve social and economic objectives in a transparent and planned way (UNESCO--IOC, 2011). The present study identifies, maps, and separates the main human activities developed in the territorial space of the Paranaguá Estuarine Complex - Paraná, Brazil (CEP) and nearby shallow platform. Through Geographic Information Systems (GIS) and remote sensing techniques, it established the conflict zones and their impact on the marine environment and quantified areas of environmental protection affected by human activities. The results shows the regions between Pontal do Sul and Ponta do Poço, the southern portion of Baía das Laranjeiras and the Rasa Platform classified with High Conflict levels. Approximately 19% of the administrative limits of the Conservation Units (CU) in the region and 33% of the Damping Zones (DZ) are affected by anthropic activities and uses. In this way, the spatialization of existing conflicts in a place with broad uses for different purposes, would support to define economic strategies; direct actions for public policies, and decision making. Still, it can be a tool for the mitigation and compensation of environmental and social impacts, due to human activities in the study area.
