water efficiency
pgleick | May 10, 2013The Colorado River, recently named America’s most endangered river, supports millions of people in the American Southwest and northwest Mexico and helps irrigate millions of acres of land. It is shared by seven states in the U.S. and Mexico, through a complex series of legal agreements and treaties.
Yet every drop of water on the river is accounted for, used, reused, and transpired away, and today, no water reaches the Colorado River delta in an average year. Quite simply, demands on the river exceed the river’s average supply, and this problem is projected to get worse as populations…
pgleick | March 21, 2013Some thoughts for today: the bad news and good news for World Water Day. [First, I think every day should be World Water Day, not just March 22nd, but hey, that’s just me.]
Stop taking your tap water for granted. Go to your tap, draw a glass of water, and drink it. Then remember that nearly a billion people still do not have reliable access to safe, affordable tap water and cannot do what you've just done.
Stop taking your toilet for granted. Nearly 2.5 billion people (more people than lived on the planet in the 1930s) don’t have safe sanitation.
Do you know anyone who had cholera, or typhoid…
pgleick | March 13, 2013Here is the second in what will be a series of posts on how little things like changes in technology we take for granted, or simple behaviors, can have a big impact on water use. The first looked at turning off the water when you brush your teeth: a seemingly trivial thing. It turned out not to be so trivial. (I will, on occasion, also blog about the “not so little” things like fundamental changes in our agricultural systems, dietary choices, and industrial processes.)

pgleick | February 21, 2013The Pacific Institute has done extensive and groundbreaking research over the past 25 years on a wide range of water, climate, energy, and environmental issues. One focus has been on how to use water more efficiently to do the things we want to do – a focus on “efficiency” and “productivity” – not deprivation.
Society could certainly cut water use by removing urban lawns, or never washing our cars again, or eliminating irrigated alfalfa in the desert. But we've never recommended these things. Why? Not because the water savings from such changes are small: some of these things can produce vast…
pgleick | February 14, 2013Invest in the future. And especially, invest in sustainable, effective job creation in the water sector. The result will be millions of new jobs – a significant result.
That is the key message from a new analysis just released today by the Pacific Institute on sustainable water jobs in the United States. That study, Sustainable Water Jobs: A National Assessment of Water-Related Green Job Opportunities, finds that proactive investments increasing efficient water use, improving water quality, expanding smart water treatment and re-use, and more will address growing problems associated with…
