Abstract
Among achievements related to the environmental protection and sustainable development of the Guarani aquifer system (GAS) project (World Bank, 2009), it was developed a framework for analyzing and classifying causes of critical issues and possible mitigation measures in a transboundary diagnostic analysis. The classified causes recognised are: natural (caused by climate change for example), primary or technical (related inter alia to low level sanitation coverage), secondary or economic management (uncontrolled use of the GAS…), tertiary or political (lack of legal norms or absence of managing institutions) and fundamental or socio-cultural (lack of public participation…). Some of these causes of critical issues resemble to the indicators or sub-indicators proposed in the evaluation method of the conflict risk's index around the transboundary water resources (Menani, 2009); method which will be tested here on the GAS’s case. In August 2010, the four countries signed the Guarani Aquifer System Agreement under the framework of MERCOSUR. Through this action, it is expected a better coordination and a joint management of this strategic shared aquifer. The current GAS data, rather reassuring, don’t mean that there isn't or that there wouldn’t be a risk of conflict about this cross-border aquifer. The problem deserves to be considered through several parameters which have an impact on the risk of conflict.
