ABSTRACT
Transboundary water-resources management is usually characterized by prior existence of conflicts. The Agreement on Guarani Aquifer, signed by Argentina, Brazil, Paraguay and Uruguay, is one of the few treaties signed in a precautionary context. Although the Plata Basin has faced many conflicts regarding surface waters, there are no conflicts in the use of shared groundwater. This paper focuses on analyzing the structure of this agreement and its capacity to prevent future conflicts and deepen the cooperation between the states.
