•Argentina has several water sweet reservoirs. In Patagonia in the Santa Cruz River and the

famous Guarani aquifer. Currently 40% of he world population has no access to clean water, and many countries import the resource. For the

next 20 years, the situation will be critical, and the water will be the main strategic resource. If today is because of war and conflict, the future

will be much more promising.

The Guarani Aquifer is a water sweet reservoir that extends below the surface of border parts of Paraguay, Argentina, Brazil and Uruguay.
