Potential Climate Change Impacts
The Uruguayan Second Communication to the UNFCCC includes and assessment of the vulnerability of water resources to the likely impacts of Climate Change. The assessment, which is also part of the National Program for Mitigation and Adaptation to Climate Change (PMEGEMA for its acronym in Spanish), states that river basins with high water resources demand and limited hydraulic infrastructure will likely be the systems affected the most by Climate Change. These impacts will be worsened by the lack of an efficient, integrated water resources management system country wide. Also, according to the Second Communication climate scenarios show that “there will be likely an increased demand of water vis a vis supply, but this ratio is far from compromising Uruguay’s water resources, except form the Merin Laggon basin, where current water balance is already stressed.”
Floods magnitude and frequency is likely to increase due to intense precipitation and land use change, especially around urban areas. Groundwater recharge will also be affected by change on precipitation, although it is not expected to be substantially lower. However, MVOTMA expects an increase in groundwater use in the future due to an increased water demand for irrigation and industrial purposes. Higher demand could increase pressure in already stressed systems such as the Raigon Aquifer and Southern areas where there is a need for groundwater integrated management systems.

Famous quotes containing the words potential, climate, change and/or impacts:
“It can be fairly argued that the highest priority for mankind is to save itself from extinction. However, it can also be argued that a society that neglects its children and robs them of their human potential can extinguish itself without an external enemy.”
—Selma Fraiberg (20th century)
“Culture is the name for what people are interested in, their thoughts, their models, the books they read and the speeches they hear, their table-talk, gossip, controversies, historical sense and scientific training, the values they appreciate, the quality of life they admire. All communities have a culture. It is the climate of their civilization.”
—Walter Lippmann (1889–1974)
“Humph! Talkin’ ‘bout me lookin’ old! When you pull down yo’ britches, you look lak de change uh life.”
—Zora Neale Hurston (1891–1960)
“We are no longer in a state of growth; we are in a state of excess. We are living in a society of excrescence.... The boil is growing out of control, recklessly at cross purposes with itself, its impacts multiplying as the causes disintegrate.”
—Jean Baudrillard (b. 1929)
