Happy
World Water Day and welcome to Water Works — a blog about the
deep and shallow aspects of our planet’s lakes, rivers, and seemingly vast
stores of underground water. Earth’s water supply works for us in thousands of
ways — we employ it to fuel energy production; we harness it to make cement and
computers; and of all of the freshwater flowing on the planet, we divert a
whopping 70 percent through increasingly elaborate irrigation systems to grow
food and other crops.
I’ve
spent the last few years taking fieldtrips of sorts with farmers, engineers,
chemists, fishermen, and a whole host of wildlife to see how we capture, treat,
and distribute this critical resource. Water Works will be a way to share some
of those stories, as well as comment on water-related news — from droughts and
fracking to river restoration and new nanotechnology filters. The blog will
keep you updated on relevant reports, projects, and peer-reviewed research that
reflect and help shape the way we perceive and interact with the fresh elements
of the hydrosphere.
WHERE IT ALL BEGAN: Two NASA satellite
photos from the agency’s Gravity Recovery and Climate
Experiment (GRACE) project show how the Qadisiyah Reservoir in Iraq
is shrinking. The reservoir, along the Euphrates River, and in the “cradle of
civilization” — where irrigated agriculture emerged nearly 8,000 years ago —
lost 117 million acre feet of water (enough water to cover 117 million football
fields a foot deep) between 2003 and 2009, according to researchers.
This was due, in part, to aggressive groundwater pumping for agriculture. As in
most watersheds, aquifers in the Tigris-Euphrates River Valley are connected
through the water table to surface waters. The United Nations has devoted this
years’ World Water Day to discussion of cooperation, instead of conflict and
potential water wars. There are few places where the line between the two is
more fragile. The Tigris and the Euphrates originate as snowmelt in the
highlands of Turkey, Iraq, and Iran, before running hundreds of miles to the
Persian Gulf. Countries in the basin, including Syria, are scrambling to secure
limited resources, as populations grow and climates dry out. Despite a series
of attempts at international water management agreements in the region over the
course of almost 70 years, Turkey maintains the upper hand, continuing to build
massive upstream dams that threaten to withhold precious supplies from
downstream neighbors.
You
have no doubt heard about the global water crisis. Scarcity and pollution
present debilitating obstacles to human and environmental health (according to the World Health Organization 780 million
people lack access to clean water). In an effort to cover these
issues without driving readers into depression, Water Works will be more about
the journey from source to tap. It will focus on landscapes and solutions,
ingenuity, and the resilience of freshwater ecosystems. It will try to capture
the culture of water. I’ll take a deep dive into debates about water management,
but also post examples of remarkable and quirky water-inspired photography,
art, and infrastructure; interview experts and authors; and revisit interesting
milestones in the history of water, and civilization. I also look forward to
hearing from readers who have their own field reports on the state of the
world’s water.
Together
we will stay afloat. Stay tuned for more…
