Argentina – June 22nd, 2013

Phytoplankton and sediments float in the waters of the Atlantic, parallel to the coast of Argentina. Sediments are particularly dense along the coast by Bahía Blanca (upper right quadrant), while two other mixed plumes can be viewed trailing off the Valdes Peninsula (center) and the southern end of the San Jorge Gulf.

Argentina – June 8th, 2013

Sediments and phytoplankton can be seen off the coast of Argentine Patagonia. The greenish plume of color streaming northeastward off Peninsula Valdes (center) is likely caused by sediments, while the band of green containing swirled patterns that is parallel, but not connected to, the coast of the San Jorge Gulf (below), is likely due to phytoplankton.

Multiple Fires in Paraguay and Argentina

Uruguay, Paraguay, Argentina – May 10th, 2013

Several plumes of smoke can be seen from fires in Paraguay (left) and in the Argentine province of Misiones, which appears darker green than the surrounding terrain. The smoke from the fires in Paraguay is blowing south-southwest, while that of the fires in Argentina is blowing due south.

Issues Affecting the Río de la Plata Basin

Argentina – May 4th, 2013

The Río de la Plata Basin, with a surface area of over 3,200,000 km2 is the second largest drainage basin in South America and the fourth largest in the world. It covers the whole of Paraguay as well as considerable parts of Argentina, Bolivia, Brazil and Uruguay, including within its central plain the most extensive corridor of fluvial wetlands on the planet, as well as some of the most densely inhabited mega-cities in South America and in the world.

The ecosystems in the region, and its wetlands in particular, are significant examples of the abundance, variety and quality of natural resources, which facilitate the production of a large number of environmental goods and services of great economic and ecological importance.

The natural resources of the Río de la Plata Basin and the associated goods and services are threatened by factors such as the fragmentation of natural ecosystems, the expansion of agricultural borders, large-scale livestock rearing, major infrastructure projects, urban development and pollution, which not only affect the wetlands and biodiversity but also the local communities that depend on these resources, not to mention food safety and the global climate.

Unsustainable production is affecting the traditional production models in the region, increasing the impact of drought and flooding, and reducing the capacity for adaptation to climate change, which has a negative impact on the welfare of local populations, creating conditions that give rise to migration to large cities and increasing
poverty (click here for more information).

Climate Change and Possibility of Flooding Along Argentine Coast – April 27th, 2013

Argentina – April 26th, 2013

The Argentine coast of the Plata River, including the metropolitan area of Buenos Aires, is subject to flooding when there are strong winds from the southeast, called sudestadas. As sea level rises as a result of global climate change, storm surge floods will become more frequent in this densely populated area.

The areas at risk of flooding during this century in Plata River coasts are very small, but the social and economic impact of the increasing frequency of floods by storm surges will be important. The number of people facing a risk of at least one flood every 100 years would be about 1,700,000 in the 2070 decade, more than three times the present population. By the same decade, those that would suffer floods every year would be 230,000, about six times the population that are currently exposed to annual flooding.

Under the assumptions that no adaptation measures would be implemented, the estimate of losses including real estate damages and the incremental operational costs of the coastal facilities for the period 2050-2100 would range from 5 to 15 billion USD dollars depending on the speed of the sea level rise and of the rate of growth of the infrastructure (click here for more information).
