Scripts for marine spatial planning in Brazil.
Warning
This project is under active development.
The PEM Project (Planejamento Espacial Marinho do Brasil, or Marine Spatial Planning for Brazil) is a national initiative focused on developing spatially explicit guidelines for the sustainable use and management of Brazil’s marine environment. It supports the implementation of Marine Spatial Planning (MSP) across the country, integrating ecological, social, and economic dimensions of the ocean.
This repository hosts R and Python scripts that ensure reproducibility of the analytical methods and mapping procedures applied in the PEM Sul (Southern Marine Spatial Plan).
Each script is designed to operate independently, targeting specific stages of the general methodological workflow. The general workflow aims to:
Convert and analyze spatial information on marine uses and habitats.
Integrate data to support ecosystem-based marine management.
Develop the Marine Use Performance Index — IDUSE-Mar (Índice de Desempenho do Uso de Serviços Ecossistêmicos do Mar), a measure that evaluates how marine uses interact with and depend on ecosystem services.
By maintaining all analytical scripts in a single repository, the project ensures transparency, reproducibility, and consistency across different PEM regional plans. The scripts can be adapted or extended for other Brazilian coastal and marine regions following the same methodological principles.
