Biologists and ecologists trying to save sharks of the Pacific waters in Central America

Biologists-and-ecologists-trying-to-saveMarine biologists and ecologists in Panama recommended the adoption of urgent changes in fisheries in the countries of Central America in order to save sharks, more and more scarce in the Pacific.

The Venezuelan researcher Hector Guzman, at the Smithsonian Tropical Research Institute (STRI) , revealed that three separate projects confirm a “very intense fishing” of sharks in Panama.

He recalled that aboard industrial ships and artisanal , scientists weighed and measured thousands of sharks. Of 18 species studied, five are in “critical condition” at the global level.

In fact, 96 percent of the catch in Panama of the hammerhead shark (Sphyrna lewini), the most valued by Central Americans fishermen are infants or juveniles. Read more

Apocalypse Is Almost Now: How Water Might Kill Us All

No one cares about the weather as a conversation starter for the next fortnight: the upcoming Armageddon forecasted by the Mayans is in our hearts and souls. There are dozens of places from where the Horsemen of Apocalypse will approach. We studied five possible scenarios of water doomsday. We do guarantee that they are not to happen on December 21st, but the possibility remains ever after.

How-Water-Might

1. Global Warming. Delayed greenhouse effect might soon become a reality. Here in Northern Hemisphere, we hope that it will start with the Antarctics, so that we’ll manage to built our arks to survive the flooding. The latter would start with Australia, New Zealand and Oceania. Japan and coastal territories of South-Eastern Asia are the next ones to be washed away. Then go the coastlines of both Americas, and after that – us, Europeans. Twenty-five per cent of solid ground of surface would shrink to 7-10%. No place to live for all seven billion people… Read more

Fresh water, the greater potential of Argentina and Paraguay

Fresh water shared by Argentina and Paraguay, source of life and energy, as well as biological and cultural diversity, are the greatest potential for both countries, facing the challenge to change the matrix based on agricultural production for export, said the Paraguayan Environment Ministry, Oscar Rivas.

cuenca-del-plata“Argentina and Paraguay are two countries that share one of the greatest treasures of mankind, the Plata basin, which is among the five hydrological systems in the world and second in the continent,” said Rivas to Télam.

In an interview at the Embassy of Paraguay in Buenos Aires, Rivas said that, “the Plata basin is one of the world’s richest territories, with Paraguay entirely within it and a good part of the most important areas of production, history , populations and Argentine economies. ”

“Whatever we do, with a positive or negative impact, is something that we have in common with Argentina, and from the fresh water that we share is derived from another element that makes the existence such as the hydropower, clean but not free from environmental impacts,” said. Read more

LATIN AMERICA: The waters are murky

waters-are-murkyMore than 20 percent of Latin Americans and Caribbeans have no basic sanitation and 15 percent of them directly without access to clean water, a resource victim of poor management, say experts meeting in Brazil.

“We must recognize that water quality is a serious problem with serious pollution situation due to mishandling and disabilities in management, and aquifers deplete its reserves at a rapid pace”, as stated by Walter Ubal, International Research Center Development, Government of Canada (IDRC ).

The super concentrates urban grow the demand for the resource and, consequently, the cost of search and purify is “high,” said the specialist in management of natural and environmental resources present at the XIV World Water Congress, held in Porto de Galinhas in northern Brazil. Read more

Energy, Water, Land Intertwined & Threatened, Says Report

Water resources, energy and land use are so mutually dependent that climate-related disruptions to any one of them could lead to economically devastating ripple effects — especially as a growing population puts increasing strains on all three. That’s one conclusion of a recent report issued by a federal advisory committee charged with assessing how climate change has already affected the U.S., and what the future holds.

The National Climate Assessment draft report, nearly 1,200 pages long, explores how the Earth’s climate is controlled by a complex system of interconnections. And, more specifically, how when the climate changes, those interconnections can make for all sorts of troubles.

“Energy projects, [including] coal-fired power, biofuel, solar farms — require varying amounts of water and land; water projects — water supply, irrigation — require energy and land; and land activities — agriculture, forestry — depend upon energy and water,” write the authors. Read more
