"A new generation of
solutions is emerging, but nowhere near fast enough."
An analysis released Tuesday
warns that 17 countries which are collectively home to a quarter of the global
population face "extremely high water stress" that is on track to get
worse—particularly because of the human-caused climate emergency.
The data is part of the World
Resources Institute's (WRI) Aqueduct
Water Risk Atlas, a publicly available database and interactive tool
designed to enhance global understanding of water scarcity, which WRI calls
"one of the defining issues of the 21st century."
"The newly updated
Aqueduct tools allow users to better see and understand water risks and make
smart decisions to manage them," WRI president and CEO Andrew Steer said in
a statement. "A new generation of solutions is emerging, but nowhere near
fast enough. Failure to act will be massively expensive in human lives and
livelihoods."
"Water stress is the
biggest crisis no one is talking about," said Steer. "Its
consequences are in plain sight in the form of food insecurity, conflict and
migration, and financial instability."
The WRI statement noted that
"the world has seen a string of water crises in recent years, as what's
now known as 'Day Zero'—the day when the taps run dry—has threatened major
cities from Cape Town to São Paolo to Chennai."
Betsy Otto, who directs WRI's
global water program, told The
New York Times that "we're likely to see more of these Day Zeros in
the future."
Otto, speaking to The
Guardian, added that
"our populations and economies are growing and demanding more water. But
our supply is threatened by climate change, water waste, and pollution."
In a blog post announcing the
new data, WRI outlined three
ways that communities and countries around the world can reduce water stress,
regardless of where they rank on the group's list:
Increase agricultural
efficiency by using seeds and irrigation techniques that require less water,
investing in developing technology that improves farming, and cutting back on
food loss and waste;
Invest in "grey"and
"green" infrasturcture, improving everything from pipes and treatment
plants to wetlands and watersheds.
Treat, reuse, and recycle
"wastewater."
The blog explained that
countries rank at WRI's highest level for water stress if their "irrigated
agriculture, industries, and municipalities withdraw more than 80 percent of
their available supply on average every year."
A dozen of the top-ranked
countries are located in the Middle East and North Africa. "The region is
hot and dry, so water supply is low to begin with," wrote WRI, "but
growing demands have pushed countries further into extreme stress."
India, which has a population
exceeding 1.3 billion, also ranks among the most water-stressed nations.
Shashi Shekhar—former
secretary of India's Ministry of Water Resources and a senior fellow at WRI
India—noted that "the recent water crisis in Chennai gained global
attention, but various areas in India are experiencing chronic water stress as
well."
"India can manage its
water risk with the help of reliable and robust data pertaining to rainfall,
surface, and groundwater to develop strategies that strengthen
resilience," Shekhar said. "Aqueduct can help identify and prioritize
water risks in India and around the world."
Behind the 17 nations at WRI's
top level are 44 countries—collectively home to another third of the world's
population—that face "high" water stress, withdrawing on average more
than 40 percent of their available supply annually.
However, as WRI's blog post
pointed out, "pockets of extreme water stress exist even in countries with
low overall water stress."
"For example, South
Africa and the United States rank #48 and #71 on WRI's list, respectively, yet
the Western Cape (the state home to Cape Town) and New Mexico experience
extremely high stress levels," the group explained. "The populations
in these two states rival those of entire nations on the list of most
water-stressed countries."
"The data is clear: There
are undeniably worrying trends in water," WRI concluded. "But by
taking action now and investing in better management, we can solve water issues
for the good of people, economies and the planet."
