Rains and drought confront to the regions in the Gran Chaco

022The Great American Chaco is one of the major geographic regions of South America, located in the Southern Cone, which extends from the current territories of in the Regionof the Great Argentinean North , Bolivia, Brazil and Paraguay, between the Paraguay river and Parana and the Andean highlands.

Although the latitudes where the Gran Chaco extends the concept is of a region that is always very warm, the fact is that due to the continental and seasonal wind regimes (especially wind currents from Antarctica) there are large variations accordance with the timetable thermal day / night and the seasons.

Today more than ever can be spoken of contrasting regions: the West and the East, though they changed roles. The Chaco is wet and rainy and the Eastern Region shows its face more dry for lack of it.

As the weather experts had predicted the coming of La Niña brought low rainfall with consequences in the various cultures of this era, such as corn, soybeans, cotton, sesame, and consumer items such as peanuts, beans, cassava and summer fruits.

The drought took over almost all of the Eastern Region, affecting precisely the most productive areas. Fortunately, in the North, the impact was not lethal and received some rainfall that favored sown.

Both in the Central Chaco and the Lower Chaco the pastures are in good condition thanks to the large amount of rainfall in recent months.

Usually in this region rainfall is distributed unevenly often: predominate in the eastern region and in the summer, being generally the winter months and dry months there, closely linked to fluctuations of El Niño periods of severe droughts .

However, this year has increased atmospheric instability which shows the extent of climate change in the region.
