Abstract
It is a huge reserve in South America region and it is considered one of the largest sources of groundwater on the planet. The GAS has strategic value for its countries, especially in a context of increasing scarcity. Its size, its physical and political complexity, as well as its “invisibility” and insufficient treatment in the international scenario, constitute some of the challenging elements for management. The article will, in the first instance, summarize the management cases for transboundary aquifers in the world. Subsequently, a physical and political characterization of the GAS will be made, so that, finally, the existing challenges for the management of this resource will be presented. In order to carry out this work, a bibliographical review of the articles and documents published in recent years concerning the management of transboundary aquifers in the world was carried out, as was done with respect to the Guarani Aquifer and its international framework.

In order to carry out this work, a bibliographical review of the articles and documents published in recent years concerning the management of transboundary aquifers in the world was carried out, as was done with respect to the Guarani Aquifer and its international framework
In the third section six challenges will be pointed regarding the management of Guarani Aquifer System (GAS) and they are: the need to continue the studies and common projects related to GAS; the absence on the international scene of new legal mechanisms that are the basis for the management of transboundary groundwater; the need for specific management instruments in the Guarani Aquifer Agreement for the management of GAS; the slowness in the process of bringing into force the Agreement of GAS; the institutional structure necessary to the implementation of Guarani Aquifer Agreement and its integrated management and the legislations for Guarani Aquifer Agreement and the risk of privatization of water resources
Summary
Through the last years the important role of aquifers in the world has become more evident, especially the transboundary ones. 592 transboundary aquifers were identified, from which 226 are transboundary subterranean hydrous bodies, according to the definition from Internationally Shared Aquifer Resources Management [1]. The American continent holds 79 transboundary aquifers and among them 29 are in South America; Brazil, in turn, shares 11 cross-border aquifers [2].
