Resumo

Niu et al. (2014), by bibliometric analysis, show that more than 60,000 articles were published between 1993 and 2012, being 59% of the production in environmental sciences and geosciences. Brazil represents only 1.4% of this academic production, despite having huge groundwater reserves. Santos and Ribeiro (2016) also verified that within the first 10 articles (listed in 3 different languages) about the SAG in academic bases, the majority addresses subjects of geosciences while other areas of study have little material in this ranking.

Are there articles in other relevant areas such as Economics, Politics or Information Technology about the Guarani Aquifer? The objective of this article is to carry out a bibliographic survey on the content of articles about SAG that approaches perspectives closer to the daily life aspects such as pollution, agribusiness, and public management, among others on the reserve.

The choice of the "economic", "environmental" and "sociopolitical" topics as content clusters is based on the Triple Bottom Line approach proposed by Elkington (1994), due to the simple logic of this methodology and the impact it has on current sustainability policies and future studies about SAG.

Searched articles from the Science Direct, Scielo, Google Scholar and Web of Science collections, using the keywords "guarani", "aquífero", "aquifer" and "acuífero" to search for material in Portuguese, English and Spanish published between 2010 and 2017. The articles had their abstracts and methodologies read and analyzed, later being separated in topics: economic and environmental impacts of groundwater exploitation, modeling and simulations used in the management and studies of groundwater, and political and social approach in aquifer management.

For the environmental, economic and technological points of view, more long-term studies in larger areas to measure impacts are needed, once the occurrence of a problem in a single-point area can spread to its vicinities. It is recommended that public authorities, companies and research institutions collaborate to better understand the SAG peculiarities in order to avoid future expenses. On the socio-political view, the Guarani Aquifer Agreement is emblematic because it is a model agreement on transboundary waters, thoughit is suggested that greater integration among members is necessary.

Water sustainability can be defined as the ability to use sufficient quantities of quality water on a local or global scale to meet human and environmental needs and to protect society from the hazards caused by natural or man-made disasters (Mays 2006). The water crisis from 2014 to 2016 showed that common sense of water abundance is a questionable idea. As seen, without the cooperation among society, private agents and the State, water management is a difficult task to be implemented to ensure sustainable water development.
