water resources
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 | May 9, 2013Municipalities are trying to find ways of dealing with the scourge of plastic bottles in their garbage, and with falling revenues from many sources. Plastic bottles have become a significant fraction of total garbage volume, and raise collection, handling, and landfill costs when they are not recycled. In 2011, according to NAPCOR (the National Association for PET Container Resources) 5.5 billion pounds of PET plastic bottles were available for recycling, but most of those bottles were not recycled.
One answer: impose a tax on bottled water.
Fewer than 1 in 3 of all PET bottles are recycled,…
pgleick | April 25, 2013The numbers are in for 2012, and they are shocking. The Beverage Marketing Corporation, which tracks sales and consumption of beverages, is reporting that sales of bottled water grew nearly 7 percent between 2011 and 2012, with consumption reaching a staggering 30.8 gallons per person. And since I (and some of you) consume almost zero bottled water every year, there are people out there drinking far more than the average.
Thirty-six years ago, this industry didn’t exist. Americans drank fewer than two gallons of bottled water per year, and almost all of that was in the form of water from big…
pgleick | April 22, 2013We live on solid ground, but the truth is, our planet is mostly covered in water. The famous writer Arthur C. Clarke noted this when he said, “How inappropriate to call this planet Earth when it is quite clearly Ocean.”
Today is Earth Day, when we celebrate the planet, and in particular the functioning ecosystem that supports all life, including our own. In recognition of Earth Day, here is a short piece about bottled water in the United States and most developed countries, with some basic facts that should help any readers still in doubt about the downsides of that industry.
The Money…
pgleick | March 31, 2013There’s nothing like spending time in the desert to make one appreciate water.
It might seem strange to some that a water wonk like me spends considerable time in the desert. I've tried to go down to the vast Southern California desert for some time every year, typically in the spring when the winter cold is receding and the days are getting longer and there is a chance of some of the dramatic wildflower blooms that the sparse desert rains can produce. The skies at night are phenomenal; the landscapes primitive, and the wildlife raw. There is no better place to see how nature adapts to…
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 20, 2013Water is a theme that runs through all forms of popular culture, from books to myths to Hollywood and international films, with a growing number of shorter video pieces posted online at YouTube and similar sites. Having trouble keeping your Netflix list populated? Below are some classic (good and bad) movies – good and bad – with some kind of water theme: conflict over water in classic western movies; science-fiction thrillers with a water component; visions of the apocalypse where water access or contamination plays a role; and more. (An early version of this list was published in the last…
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.)
The Pacific Institute has done extensive and groundbreaking research over the past 25 years on a wide range of water, climate…
pgleick | March 11, 2013In a previous post here, I discussed the scourge of cholera – a waterborne disease largely vanquished in the wealthier nations by our water and wastewater treatment systems. Unfortunately, it remains widespread and lethal. Cholera is perhaps the most common and serious water-related disease, directly associated with the failure to provide safe drinking water and adequate sanitation to billions of people. Millions – mostly young children – die unnecessary deaths each year from these diseases.
This week is the 200th anniversary of the birth of the man who would help settle, once and for all,…
pgleick | February 27, 2013OK, put away your guns. We’re not talking shooting wars, at least not yet, at least not in the U.S. We’re talking politicians shooting off their mouths, political wars, and court battles. But water is serious business.
But it is a different story around the world, where there is a long and sad history of violent conflict over water. At the Pacific Institute we maintain the Water Conflict Chronology, documenting examples going back literally 5,000 years.
As others have pointed out, water can be – and often is – a source of cooperation rather than conflict. But conflicts over water are real.…
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 20, 2013One of the reasons that climate change is such a big issue is because the global climate is an integral part of the Earth’s entire ecosystem, tied to so many of the big and little things that society cares about. Figuring out how all these complicated pieces tie together is hard, as is linking these pieces together in the minds of the public so that we – and our policy makers – can grasp the true implications of a changing climate and plan for them. Because this is so important, I expect that many of my future posts here will address this issue, but let me start with one example: the…
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…
pgleick | February 13, 2013We’re bombarded with numbers every day. But seeing a number and understanding it are two different things. Far too often, the true “significance” of a figure is hidden, unknown, or misjudged. I will be returning to that theme often in these blog posts in the context of water, climate change, energy, and more. In particular, there is an important distinction between accuracy and precision.
Here is one example – reported cases of cholera worldwide. Cholera is perhaps the most widespread and serious water-related disease, directly associated with the failure to provide safe drinking water and…
pgleick | February 10, 2013It is time we just said “no.”
There is growing attention to climate change in the media; and there is a growing realization that decisions we make today will have a lasting effect on the world’s climate tomorrow.
But there is still a gap – a chasm really – between the reality of climate change and our day-to-day choices, investments, and public debates about water, energy, food, and resources.
Here is the reality: the burning of fossil fuels is the leading contributor of gases that are already changing the planet’s delicate climate, and the climate will continue to change in an exponentially…
