If left unattended, the twin engines of urbanisation and resource depletion will undermine efforts to achieve and sustain water security: water availability and access will be eroded and conflicts over use will escalate.

The Guarani Aquifer is a huge system of Triassic-Jurassic sandstones (mainly of Aeolian origin) underlying more than 1 million km2 of Brasil (62% of area), Paraguay Uruguay & Argentina – with around 30,000 km3 of fresh groundwater in storage, a current rate of exploitation of just over 1 km3/a (94% in Brasil) and major potential for municipal and industrial water-supply, supplementary irrigation and hydrogeothermal resources (reaching 40-60 C in its more deeply-confined sections).
The quality of groundwater recharging the aquifer is threatened in some areas by rapid land-use changes (from natural forest to arable soya-bean cultivation), and locally by rapid urbanisation – but only very locally are there indications of excessive groundwater abstraction (eg. Ribeirao Preto-Brasil) or transboundary groundwater resource or quality dimensions (eg. Rivera-Uruguay/Santana do Livramento-Brasil, Ponta Pora-Brasil/Pedro-Juan Caballero (Paraguay), Concordia (Argentina)-Salto (Uruguay).
