Acaparamiento de agua se da en ‘tasas alarmantes’

Los tratados por los cuales compañías y países extranjeros compran o arriendan tierras agrícolas en el extranjero significa que se apropian de casi medio billón de metros cúbicos de agua dulce cada año –lo suficiente para cultivar alimentos y abatir la desnutrición en los países “saqueados”

A parched future: Global land and water grabbing

Rulli and colleagues estimate that global land grabbing is associated with the grabbing of 308 billion m3 of green water (i.e. rain water) and an additional grabbing of blue water that can range from 11 billion m3 (current irrigation practices) to 146 billion m3 (maximal irrigation) per year. To put these numbers in perspective, the average daily household consumption of water in the UK is 150 liters (0.15 m3) per person.

Global land and water grabbing

It is found that about 0.31 × 1012 m3⋅y−1 of green water (i.e., rainwater) and up to 0.14 × 1012 m3⋅y−1 of blue water (i.e., irrigation water) are appropriated globally for crop and livestock production in 47 × 106 ha of grabbed land worldwide (i.e., in 90% of the reported global grabbed land).

Grabbing at solutions: Water for the hungry first

This piece is part of "Water Grabbers: A Global Rush on Freshwater", a special National Geographic News series on how grabbing land—and water—from poor people, desperate governments, and future generations threatens global food security, environmental sustainability, and local cultures.

Regar con lágrimas

Que la agricultura industrial está detrás del uso intensivo del agua es una realidad no suficientemente conocida ni denunciada, sobretodo cuando sabemos que usa más agua de ríos, lagos y acuíferos que la que reponen las lluvias o las nieves.
