Table 2 I was World Water Forum in Marrakech, Morocco, in March 1997; II was World Water Forum in The Hague, Netherlands, in 2000; III World Water Forum was held in Kyoto, Shiga y Osaka, Japan, in March 2003; IV World Water Forum held in Mexico City in March 2006. being canceled. In Uruguay, there plebiscite ensured that water as a public good and therefore should be managed by the State (2004), in Bolivia, there was termination of service after protests of the population (2005). Many actions have been taking place to ensure the management of public water and its distribution at low cost. Among them is the realization of the World Water Forum, which is in its fourth version. According to its organizers, the main purpose of the event is to define suitable ways by which the distribution is guaranteed universal and sustainable resource. Note, in Table 2, the chronology of the event. According to several surveys, water is becoming an increasingly scarce resource, and rightfully so, its management has been subject to economic and political interests. In 2002, the UN document called "Global Challenge, Global Opportunity" presents information such as: 40% of the world population has difficulty in getting drinking water, 2.2 million people die each year from drinking contaminated water; 2025 will be 4 billion people without access to water. Based on the figures provided by the UN, we can say that the control of water use means hold the power? If we go back to the beginning of the Leafs, we see that 22.4% of the available water on the planet is below the surface. Ie, there is more water in the subsoil than in rivers and lakes. "The land or geological formations that store groundwater are called aquifers" According Scotti (2005), UNESCO has records regarding use of groundwater and the problems arising from the misuse of these reserves. Aquifers vary in size and depth. Among the world's most important is the Guarani Aquifer or Guarani Aquifer System (SAG), which occupies 1.2 million km in the territories of Argentina, Brazil, Paraguay and Uruguay. The total area of the aquifer, most are located in Brazilian territory - about 840,000 km Includes part of the following units of the federation: Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Minas Gerais, Goiás, Mato Grosso and Mato Grosso do Sul See Figure 3 the location of the Guarani Aquifer. There are 45 trillion cubic meters of water, according to Scotti (2005), require more research about its quality.

Tablica 2 Bio sam World Water Forum u Marakeš, Maroko, ožujak 1997; II bio svjetskog foruma o vodi u Haagu, Nizozemska, 2000; III World Water Forum održan je u Kyotu, Shiga y Osaka, Japan, ožujak 2003; IV World Water Forum održan u Mexico City u ožujku 2006. je otkazan. U Urugvaju, postoje plebiscitarnu osigurati da se voda kao javno dobro i stoga treba upravljati od strane države (2004), u Boliviji, tu je prestanak službe nakon prosvjeda stanovnika (2005). Mnoge akcije se održava kako bi se osiguralo upravljanje javnim vode i njegove distribucije po niskoj cijeni. Među njima je i realizacija Svjetskog foruma o vodama, koji je u svojoj četvrtoj verziji. Prema organizatorima, glavna svrha manifestacije je definirati prikladne načine kojim se jamči univerzalni distribucije i održivih izvora. Napomena, u tablici 2, kronologija događaja. Prema nekoliko istraživanja, voda postaje sve oskudniji resurs, i to s pravom, njegov menadžment je bio predmet ekonomskih i političkih interesa. U 2002, UN-a dokument pod nazivom "Global Challenge, Global Opportunity" predstavlja informacije kao što su: 40% svjetske populacije ima poteškoća u dobivanju pitke vode, 2,2 milijuna ljudi umire svake godine od pijenja zagađene vode; 2025 će biti 4 milijarde ljudi bez pristupa vodi. Temelji se na podacima koje je UN, možemo reći da je kontrola uporabe voda znači držite? Ako se vratimo na početak Listovi, vidimo da je 22,4% od raspoložive količine vode na planetu je ispod površine. Odnosno, postoji više vode u podzemlje nego u rijekama i jezerima. "Zemljište ili geološke formacije koje su trgovine podzemnih vodonosnika pod nazivom" (Stijena, 2002, str. 25) Prema Scotti (2005), UNESCO ima evidenciju o korištenje podzemnih voda i problema koji proizlaze iz zlouporabe tih rezervi. Akviferi varirati u veličini i dubini. Među najvažnijim svjetskim je Guarani vodonosnika ili Guarani vodonosnika sustav (SAG), koja zauzima 1,2 milijuna km na području Argentine, Brazila, Paragvaja i Urugvaja. Ukupna površina vodonosnika, većina se nalazi u brazilskom teritoriju - oko 840.000 km Uključuje dio od sljedećih jedinica u Federaciji: Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Minas Gerais, Goias, Mato Grosso i Mato Grosso do Sul Pogledajte sliku 3. mjesto u Guarani vodonosnika. Postoji 45 trilijuna kubičnih metara vode, prema Scotti (2005), zahtijevaju više istraživanja o njegovoj kvaliteti.
