the planet’s climate in flux, rivers will both flood and run dry
often, according to the latest report from the International
on Climate Change. Shortages are especially likely in parts
world already short on water, so political scientists expect
will become even more intense. To track disputes worldwide,
rchers at Oregon State University spent a decade building a
rehensive database of international incidents—both aggressive
ooperative—over shared water resources. They found that
ries often begin disputes belligerently but ultimately reach
ful agreements. Says Aaron Wolf, the geosciences professor
eads the project, “For me the really interesting part is how even
and Israelis, Indians and Pakistanis are able to resolve their
ences and find a solution.” KATIE PEEK

The map displays nearly 2,000
international incidents, collaboration
and conflict alike, over shared river
basins from 1990 to 2008. The areas
of the circles in the sidebar [facing
page] compare about 2,200 events—
including another 200 disputes over
resources other than shared rivers—
from the same period.

The color of each international river basin shows the total number of
incidents there, both aggressive and cooperative, from 1990 to 2008.
Circle size indicates the number of hostile events in each basin.

INCIDENTS BY INTENSITY The researchers graded each event in their database on a 15-point scale.
CURRENT HOTSPOT
In 2011, Ethiopia began
building the Grand
Renaissance Dam on the
Blue Nile, a tributary that
provides 60 percent of
the Nile’s water. Without
any basin-wide treaties in
place, Egypt and Sudan are
concerned about receiving
enough water downriver.
Ethiopia plans to complete
the project in 2017.
CURRENT HOTSPOT
Later this year Turkey
will complete the Ilisu
Dam on the Tigris River,
part of a national push to
boost electrical capacity.
Besides submerging
the 12,000-year-old
settlement of Hasankeyf,
the dam may damage Iraq’s
Mesopotamian Marshes
by allowing them to get
saltier. Germany, Austria,
and Switzerland withdrew
funding for the dam in 2009.
CURRENT HOTSPOT
In a channel of the Mekong
two miles north of the
Cambodian border, Laos
intends to construct
the Don Sahong Dam.
The power project would
affect fishing in Cambodia,
Vietnam, and Thailand,
and those countries are
demanding veto power.

CURRENT HOTSPOT
Tajikistan is planning the
Rogun hydroelectric dam
on a tributary of the Amu
Dar’ya river. The dam would
be the tallest in the world
and help alleviate the
country’s energy shortages.
Uzbekistan, fearing
irrigation shortfalls, has
imposed tariffs and travel
restrictions on its neighbor.
