Water, Water Everywhere, But Nary a Drop to Drink

It is a unique challenge of our generation that many in the developing world have cellular phones and TVs, but lack reliable access to water. Odd, perhaps, given that water is marketed as essential for life, a human right, and heart rending pictures of women and children walking miles to fetch water are routinely flashed to tug at everyone’s heart strings.

In many developing countries growing populations and limited investment in infrastructure are leading to declining access to water. Even in the United States, the impact of droughts on urban supply is larger today than ever before, as witnessed in the South in recent years. 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

Andean and Patagonian Glaciers Melting in a Hurry

pastoruriIce fields in Andean South America are rapidly losing volume and in most cases thinning at even the highest elevations, contributing to sea-level rise at “substantially higher” rates than observed from the 1970s through the 1990s, according to a study published recently. The findings spell trouble for other glaciers worldwide.

The rapid melting, based on satellite observations, suggests the ice field’s contribution to global sea-level rise has increased by half since the end of the 20th century, jumping from 0.04 millimeters per year to about .07 mm, and accounting for 2 percent of annual sea-level rise since 1998.

The southern and northern Patagonian ice fields are the largest mass of ice in the southern hemisphere outside of Antarctica. The findings spell trouble for other glaciers worldwide, according to the study’s lead author, Cornell University researcher Michael Willis. Read more

Water: How much should you drink every day? (continued)

Factors that influence water needs

You may need to modify your total fluid intake depending on how active you are, the climate you live in, your health status, and if you’re pregnant or breast-feeding.

Exercise. If you exercise or engage in any activity that makes you sweat, you need to drink extra water to compensate for the fluid loss. An extra 400 to 600 milliliters (about 1.5 to 2.5 cups) of water should suffice for short bouts of exercise, but intense exercise lasting more than an hour (for example, running a marathon) requires more fluid intake. How much additional fluid you need depends on how much you sweat during exercise, and the duration and type of exercise. During long bouts of intense exercise, it’s best to use a sports drink that contains sodium, as this will help replace sodium lost in sweat and reduce the chances of developing hyponatremia, which can be life-threatening. Also, continue to replace fluids after you’re finished exercising. Read more
