Title: The Plata Basin covers about 3'6 million km2'


1
The La Plata Basin
  • The Plata Basin covers about 3.6 million km2.
  • The La Plata Basin is the fifth largest in the
    world and second only to the Amazon Basin in
    South America in terms of geographical extent.
  • The principal sub-basins are those of the Parana,
    Paraguay and Uruguay rivers.
  • The La Plata Basin covers parts of five
    countries, Argentina, Bolivia, Brazil, Paraguay
    and Uruguay.

2
Global relevance of the la Plata Basin
  • LPB is home of more than 100 million people
    including the capital cities of 4 of the five
    countries, generating 70 of the five countries
    GNP.
  • The fluvial transport of the Paraguay-Paraná
    Waterway was of 13,000,000 tons in 2004.
  • The hydroelectric potential is estimated at
    92,000 MW. There is more than 150 dams, and 60
    of the hydroelectric potential is already used.
  • It is one of the largest food producers
    (cereals, soybeans and livestock) of the world.

  • What climatological and hydrological factors
    determine the frequency and spatial extent of
    floods and droughts? 
  • How predictable is the regional weather and
    climate variability and how predictable are their
    impacts on the hydrological, agricultural and
    social systems of the basin?
  • What are the impacts of global climate change and
    land use change on regional weather, climate,
    hydrology and agriculture? To what extent can
    their impacts be predicted?

Interdecadal variations of the SAM and its impact
on South America
Correlations of the SAM index with in-situ
precipitation (a-b), in-situ SLP (c-d),
reanalyzed SLP (e-f), Z500 (g-h), WIND850 (i-j)
and in-situ surface temperature (k-l). Colours
indicate values statistically significant at 90
and 95 levels. Grey dots in cases of in-situ
observations indicate stations with no
significant correlation.

CLARIS LPB Expected Impacts
  • Strengthening of the cooperation between European
    and South American multidisciplinary research
    communities
  • Improvement of climate change impact prediction
    capacity for the region through the setting-up of
    an ensemble of mutli-discipinary scenarios
    integrating in a coordinated way large-scale
    climate, regional climate, hydrological,
    land-use, and agriculture partners.
  • Dissemination of adaptation strategies
    (specifically designed for land-use, agriculture
    production, rural development (small farmers),
    hydropower, flood risk, wetlands ecological
    systems, river navigation, and near-river
    urbanization) based on ensembles of probable
    climate change scenarios for the period 2010-2040
