Análise do conflito de uso da água no perímetro irrigado de Sumé / PB utilizando o modelo GMCR.

Abstract

In this paper, a methodology was developed to support the structure of the Graph Model to Conflict Resolution (GMCR), the proposed methodology was divided into five steps starting with the collection of preliminary conflict data, which helps in identifying the main decision makers, their preferences, possible states and ending with an analysis step.Subsequently, the model was used to analyze a conflict related to water resources management in the Sucuru River basin in the Brazilian semiarid. The use of the proposed methodology provided a well structured, robust and unbiased description of the conflict, which facilitated the modeling of the problem.The conflict involves four decision makers (Rural producers, National Department of Drought Works, Federal Government / National Water Agency and Paraíba Water and Sewage Company) and eighty-four viable states were obtained. Based on the preferences of the decision makers, four steps were considered equilibrium according to different types of stability criteria.However, analysis of these solutions indicated that one of them should be adopted. In this solution, the conflict emerges from the status quo and indicates that the most likely solution would be to carry out the PIS restoration work and clear the banks of the Sucuru River.
