Once-unthinkable water crises are becoming commonplace.
Reservoirs in Chennai, India’s sixth-largest city, are nearly dry right now. Last year, residents of Cape Town, South Africa narrowly avoided their own “Day Zero” water shut-off. And the year before that, Rome rationed water to conserve scarce resources.
The reasons for these crises go far deeper than drought: Through new hydrological models, WRI found that water withdrawals globally have more than doubled since the 1960s due to growing demand – and they show no signs of slowing down.
New data from WRI’s Aqueduct tools reveal that 17 countries – home to one-quarter of the world’s population—face “extremely high” levels of baseline water stress, where irrigated agriculture, industries and municipalities withdraw more than 80% of their available supply on average every year. Forty-four countries, home to one-third of the world, face “high” levels of stress, where on average more than 40% of available supply is withdrawn every year. (Check your country’s water stress level in the full rankings at the end of this post.) Such a narrow gap between supply and demand leaves countries vulnerable to fluctuations like droughts or increased water withdrawals, which is why we’re seeing more and more communities facing their own “Day Zeros” and other crises.
