Study Finds We Vastly Underestimate Water Management’s Depletion of Freshwater

dam-reservoir

Here’s a frightening word of the day: “evapotranspiration.” It simply refers to water lost to the atmosphere by evaporation, or after being consumed and released into the air by plant life. It wasn’t so ominous last week, but it is this week because a new study in the journal Science puts it in a new context: unsustainable human use of freshwater.

Essentially, the study finds human have used 18 percent more of the planet’s freshwater than we previously thought, because we’ve underestimated the impact of our water-management systems, such as irrigation, dams and reservoirs. They cause more water to be lost to the atmosphere than would occur naturally, effecting precipitation patterns. Gather a lot of water in one place, like a reservoir, for instance, and more of it evaporates across the greater surface area exposed to air. The researchers studied the ratio of evapotranspiration to precipitation between 1901 and 2008, finding a significant increase in the latter half of the time period.

The additional 18 percent tips our water use into the unsustainable category given the increasing human population, the researchers warn. As Chelsea Harvey writes in her article about the study in The Washington Post, “The study highlights a critical need for better monitoring of our freshwater use and the ways our management techniques can affect the water cycle, as [study co-author Fernando] Jaramillo noted that the current effects of human water management ‘are even larger and more recognizable than the effects of atmospheric climate change.’”

Why You Should Give a Crap About World Toilet Day

Nov. 19, 2015, marks “World Toilet Day,” which may sound like some sort of a punchline to people who have lived their lives with easy access to modern sanitation, taking it for granted. But in the world at large, one in three people — about 2.4 billion spread throughout many countries — lacks a toilet or latrine. The resulting “open defecation” compromises human health, dignity and security, the environment, and social and economic development, the United Nations says.

To state a few related examples, poor or absent sanitation spreads diarrhoeal diseases, a leading cause of death in children. It keeps large numbers of girls out of school, depriving them of an education. It also makes women and girls vulnerable to attack as they go outside to “go to the bathroom” (where there is no such room, and very little privacy).

“We have a moral imperative to end open defecation and a duty to ensure women and girls are not at risk of assault and rape simply because they lack a sanitation facility,” UN Secretary-General Ban Ki-moon said in his message for World Toilet Day, which focuses this year on the theme of “Equality, Dignity and the Link Between Gender-Based Violence and Sanitation.”

After the UN General Assembly and Human Rights Council affirmed the human right to water and sanitation in 2010, people first questioned whether they should be called out separately or remain embedded in other human rights in which they play a role, such as the rights to a healthy environment and an adequate standard of living. Interested parties continue to discuss whether water and sanitation should be one right or two. They’re clearly related in many ways, but each sometimes requires — and deserves — separate consideration. How to do this, especially in the context of the new Sustainable Development Goals adopted at the UN in September, is an ongoing question. Goal 6 currently keeps the two together.

While the human right to water has become a hot-button issue due to increased alarm over scarcity and threats of conflict, sanitation has grabbed fewer headlines and may be relegated to the status of a “poor cousin,” to borrow a phrase from Inga T. Winkler, a scholar in residence at the Center for Human Rights and Global Justice at the New York University School of Law. I was fortunate enough recently to attend a forum where she discussed her  forthcoming academic paper outlining the evolution of the human right to water and sanitation, as well as the case for separation. Winkler is a prominent scholar in the human right to water and sanitation, having authored a seminal book on the subject and served as a legal advisor to the first UN Special Rapporteur on the Human Right to Water and Sanitation, Catarina de Albuquerque.

Open defecation and other problems of poor sanitation aren’t easy to talk about, but overcoming taboos through open discussion is crucial to making practical changes that save lives and help realize the human right to sanitation worldwide.

In the Media: Big Agriculture’s Unsustainable Use of Groundwater

panoramic-images-flooded-rice-paddy-fields-central-valley-california-usa

Thanks, Vice Media, for covering California agriculture and its massive and unsustainable use of groundwater during the state’s worst drought in, reportedly, 1,200 years. Watch the video. Or click on other posts, below.

Imagine you had a giant tank full of clean water, but it was running dangerously low. Imagine you knew it would take thousands of years, or more, to replenish that tank. How careful would you be with that faucet? Well, somebody’s leaving it running.

Curtailing Big Ag’s Water Use in California

Image: iStockPhoto.com

When drought-struck California moved to curb consumers’ use of water, I wrote about agriculture’s massive and under-regulated use of water. On Friday the state moved to cut many farmers’ use of water, in terms of some of the older rights-holders who divert water from Central Valley rivers and streams. In spring, cuts were made to thousands of junior rights holders’ usage, including many growers. This is more than the state did when it curtailed Big Ag’s water use nearly 40 years ago, in 1977, the last time it made such a move. What it hasn’t done is to move strongly to curtail the industry’s waste of the water it’s allocated to use, which is to say …  it’s allowed to use most of it (about 80 percent).

Just for “fun,” here’s an annoyingly educational reminder that most Americans make the California drought worse by eating the food grown there. That’s not to say they should forego the glorious bounty and cramp the world’s 8th largest economy, but some would argue just that, more or less. Let’s say that some of Cali’s major crops — rice, almonds, avocados — should be grown where there is ample water because they need so damn much of it. Maybe not so much compared to raising beef, but still — a lot.

Another not-fun thing: Sucking up the groundwater is making the surface of California sink faster than ever before, and it’s going to cost a lot of money as infrastructure like bridges and roads suffers damage.

World Water Day: UN World Water Development Report Warns of Global Crisis by 2030

The way water is managed now, or not managed as the case may be, will lead to a global crisis in 15 years, a new UN report warns, unless an array of sustainable water-management practices are adopted. Within that decade and a half, the report predicts a much larger human population will have only 60% of the freshwater it needs.

Many parts of the world are suffering water stress to varying degrees now; in 15 years the stress will be more severe and more widespread, amounting to a life-threatening crisis in water-poor regions. But, as outlined in the United Nations World Water Development Report 2015, released in advance of World Water Day (today, March 22), there is hope. Read the report: Water for a Sustainable World (The report was released by UNESCO on behalf of UN-Water, or which my employer, WaterLex, is a member.)

When Smog Killed Thousands, 62 Years Ago This Week

smog-policeman-with-mask

Dec. 4th: On this day in 1952, a heavy blanked of smog settled over London. Before it cleared, about four days later, it caused respiratory illness so severe that up to 12,000 people died, according to estimates. The weather had been cold, so home furnaces burning coal added a lot of extra smoke and soot to factories’ and vehicles’ output. When cold air moving in from the west collided with a high-pressure air mass arriving from the east, the pollution was temporarily trapped over the city.

If you were walking down the street on Dec. 7 that year, you could see as little as 15 feet in any direction, thanks to the heavy haze. Unfortunately, you can still have that experience today, in places like Beijing. The Great Smog of ’52, aka the Big Smoke, contributed to the creation and passage of the UK’s Clean Air Act of 1956 and other measures that reduced coal burning. Nevertheless, another series of really bad air days followed, exactly 10 years later, in Dec. 1962, killing about 750 Londoners.

War Is Hell, Part 941: The Environment

burning oil fields

In case you missed it, the United Nations’ (UN) International Day for Preventing the Exploitation of the Environment in War and Armed Conflict was Thursday, Nov. 6. Its point is to educate people about the damaging effects of armed conflict on the environment. Natural resources are often military targets — poisoned wells, torched crops and oil reserves, tainted soil —  and often remain ruined long after the battle is over, compromising ecosystems. The UN General Assembly first declared the day on Nov. 5, 2001, and it has remained not-exactly-famous ever since.

“We must use all of the tools at our disposal, from dialogue and mediation to preventive diplomacy, to keep the unsustainable exploitation of natural resources from fueling and financing armed conflict and destabilizing the fragile foundations of peace,” said UN Secretary-General Ban Ki-moon. So true.
