[Economist] Ce papier explique la situation de plus en plus sérieuse en Australie.
Although the Murray-Darling is Australia’s longest river system, draining a basin the size of France and Spain combined, it no longer carries enough water to carve its own path to the sea.
… Many of the world’s rivers, including the Colorado in America, China’s Yellow river and the Tagus, which flows through Spain and Portugal, are suffering a similar plight. As the world warms up, hundreds of millions of people will face the same ecological crisis as the residents of the Murray-Darling basin. As water levels dwindle, rows about how supplies should be used are turning farmers against city-dwellers and pitching environmentalists against politicians. Australia has a strong economy, a well-funded bureaucracy and robust political institutions. If it is struggling to respond to this crisis, imagine how drought will tear apart other, less prepared parts of the world.
