NASA’s Global Freshwater ‘Selfie’ Catches Us in the Act of Over-Depletion

U.S. space agency NASA’s new analysis of 14 years of satellite data shows rapid change in the world’s freshwater supply in startling detail never captured before. The 34 “trends” in the data picture not only the effects of climate change, like worsening droughts, but of human over-use, such as pumping out underground aquifers to irrigate crops. To a lesser extent, they show natural change over time. They also  indicate where water scarcity is most likely to reach crisis mode and lead to armed conflict over resources and/or forced human migration.

“There are implications in that map for food security, for water security and for human security in terms of things like conflict and climate refugees,” said Dr. Jay Famiglietti, a water-resources expert affiliated with NASA’s Jet Propulsion Laboratory and co-author of a paper on the findings in the journal Nature. He and other experts said the mapping should serve as a wake-up call for policymakers.

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.’”

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.

Set Heading for World Water Week in Stockholm

4951481766_c8dced02ba_z

In a couple of days I’ll join colleagues from WaterLex at one of the most prominent events in the world of water-related agencies, NGOs, services, and the like — World Water Week in Stockholm, which runs Aug. 31 – Sept. 5 in the Swedish capital, under the auspices of the Stockholm International Water Institute (SIWI). The theme this year, for this and other events around the world, is “energy and water,” two vital forces that are always interconnected.

WaterLex will exhibit in a booth shared with other organizations in the Swiss Water Partnership, and we’ll also put on a lunchtime side event on Monday, Sept. 1: Water & Energy Nexus: Smart Investments to Help Realize Human Rights. Co-convened with the UN Environment Programme (UNEP), the event’s panel discussion will explore how wastewater reuse for energy production can serve populations’ rights to adequate sanitation and a safe and healthy environment, while also making for a valuable investment in sustainability. Check out the speakers and topics. I’ll be the guy “moderating” (more like trying to keep up) or running around with a camera, taking photos for the press materials.

It will be my first time in Stockholm, so I hope to get around town a bit. A colleague recommended the Vasa Museum, the only preserved 17th century ship in the world. It heeled over and sank only minutes into its maiden voyage in 1628, and was raised in 1961. And of course there’s a museum dedicated to Abba.

Slightly more than a third of the United States suffered moderate or worse drought as of July 22, and about 40% of the country has been abnormally dry in recent months, according to research cited in The New York Times. Climate change is intensifying drought and changing patterns. While the West dries out, especially California and southwestern states, more rain than usual has been falling east of the Mississippi River. Look at the mapping on NYT Interactive’s The UpShot.

Heading for Foul Waters at the 2016 Rio Olympics

Imagine that: One moment you’re focusing on the tiny rigging adjustments that may help qualify you for sailing events in the upcoming Rio Olympics, and the next you’re swimming in sewage because your boat hit a submerged sofa that someone threw away.

Olympic sailing hopefuls are reporting that Rio de Janeiro’s Guanabara Bay, site of the 2016 Summer Olympics’ sailing and windsurfing events, is truly fouled by raw sewage and garbage. One Brazilian athlete says he’s come across four human corpses while sailing on the bay.

Brazil is making major efforts to clean up the site, but many critics fear it’s too little, too late. This is just the latest take on a familiar Olympics story: huge construction costs and delays, allegations of managerial incompetence, corruption, and human rights violations, and a sense of sinking dread over misplaced priorities. But you can’t argue with the TV ratings.

A Grim Climate-Change Forecast for the U.S.

Before too long, much of South Florida could be underwater. Alaskan forests could die at increasing rates as melting permafrost releases methane into the atmosphere. Rising oceans could make storm surges even more devastating to East Coast cities, even as drought and wildfires torment the Southwest. Those are just a handful of examples among many. The new National Climate Assessment came out on Tuesday in the U.S., bringing alarming news of how climate change, unless curbed by  drastic changes in human behavior — if that’s even possible at this point — will wreak havoc on different regions in different ways. About 300 scientists from academia, government and the private sector contributed to the report.
