Regulation of surface and subterranean fresh water in the MERCOSUR regional integration

Abstract

This work discusses the regulatory standardization among countries that are party to MERCOSUR. This standardization forms the legal and institutional framework for maintaining important and strategic water resources, which require such regulation in order to be preserved and protected for present and future generations. Due to the lack of general legislation relating to MERCOSUR’s water resources, it was necessary to study the main multilateral agreements among the MERCOSUR countries, such as the Amazon Cooperation Treaty and the River Plate Basin Treaty relating to surface water, and also the legal points included in a recent joint statement of the presidents of the Mercosur States regarding the Guarani Aquifer, which is an important resource for current and future generations of the MERCOSUR. The survey was developed using the hermeneutical method, based upon surveys and analysis of international legislation involving MERCOSUR member states, multilateral treaties relating to transboundary waters and groundwater zones and also included a search of bibliographic materials, books, journals, thematic maps, information and documents available on the Internet. The combination of the sparse legal rules covers most legal relationships between MERCOSUR member states relating to water.
