Environmental security series looks at potential rising tide of water conflicts
Although water is a scarce resource in many parts of the world, more often
than not, countries that share water basins have been able to hammer out
cooperative agreements for water rights, according to an expert on international
water issues.
Speaking to a Lab audience Monday, Aaron Wolf, assistant professor of
geography at Oregon State University, said "only seven times in modern
history have shots been fired and armies mobilized across international
boundaries" over water issues. By contrast, he noted, 3,600 water
treaties have been signed during that same time period.
"Two-thirds of the events we have looked at were cooperative —
even among countries that don’t like each other," Wolf said.
Once an agreement is signed, he added, they tend to be more resilient
even as conflict is waged over other issues.
But as the world population grows and water resources become even more
scarce, the potential for conflict will increase. About one billion people
in the world today lack access to safe water, Wolf said. That number is
expected to rise to three billion people by 2015.
"By 2050, more people will be in water stress than there are in the
world today," he said. "The numbers are not going away and will
continue to get worse."
Wolf is currently working on a project to help identify future trouble
spots internationally that could help policymakers establish cooperative
agreements before conflicts arise.
"Wouldn’t it make sense to figure out which basins are going
to be in dispute and begin resolving the issues before it becomes a conflict?"
he said.
Wolf was the first speaker in a new lecture series, "Environmental
Security and the International Water Crisis," co-sponsored by the
Lab’s Center for Global Security Research and the Energy and Environment
Directorate.
Wolf established and coordinates the Transboundary Freshwater Dispute
Database Project. He started working on the project eight years ago, but
much of the information for the database was compiled in the last two
years by Wolf and 10 students.
When they began their research, they found little information on international
water issues was readily available.
"We really don’t know a lot about shared basins. We’re
trying to document it more empirically," Wolf said.
Using World War II topography maps as well as digital elevation models
and satellite imagery, his students painstakingly mapped 261 water basins
that have international borders. They have also identified all tributaries
leading off from those water basins and are adding it to the database.
In addition, the database contains more than 150 water-related treaties
dating from 1874, related news articles on water-related disputes as well
as other published articles. The new work on basins at risk will be added
once it’s published, he said.
Wolf and his students have been looking back through history for indicators
of when water caused both conflict and cooperation. Those indicators can
include population growth, death rates, drought, political instability
and cultural differences.
"Ninety percent of the time, the disputes are over quantity,"
Wolf said, adding that the Middle East and North Africa are the most conflicted
regions in the world.
Historically, he said, the stability or instability of a government has
been the best indicator of a water conflict.
"Almost all indicators turn out not to be physical, but institutional,"
Wolf said. Strong democracies and autocracies tend to be fairly stable
on water issues, he noted, while governments in transition have the most
conflict.
In the last century, the periods with the highest amount of water conflicts
occurred after World War II with the breakup of the British Empire and
after the Cold War with the breakup of the Soviet Union.
"When countries break up, there is more conflict as a water basin
suddenly has national borders," Wolf noted.
