Bolivian Water Crisis as Glaciers Vanish, Population Grows

GR:  Many places will have to begin pumping groundwater.  That’s a temporary solution, however.  Here in the arid western United States, we’ve seen what happens as the depth to water falls and the cost of pumping rises. We’ve also seen how toxic metals concentrate in shrinking groundwater aquifers.

One glacier on Chacaltaya mountain… has already completely disappeared.

“Bolivia’s government was recently forced to declare a state of national emergency — a terrible drought, said to be the worst in at least the past 25 years, plus increasing demand in the form of population growth have left the country high and dry.

“As of now, the country is trying to drill their way out the predicament with “emergency wells.” In the city of La Paz, the three main reservoirs that provide the city’s water are almost dry. It is reported that five other major cities also face severe water shortages. Hospitals are working at half capacity and suspending non-emergency surgeries and dialysis. In some poor neighborhoods taps have run dry for three weeks. The Guardian has posted a photo-essay of the situation here.

“One key aspect of the trouble is that Bolivia’s glaciers have dramatically shrank, and so the dams that rely on continuously capturing glacial run-off are rendered somewhat worthless at this point. Bolivia’s population is expected to increase by 50% (to 15 million) by the early 2040’s.” —Joe Bish, Population Media Center (Read mre here:  Bolivian Water Crisis as Glaciers Vanish, Population Grows)

Groundwater a huge factor in sustaining Colorado River flows

New study helps resource managers plan for climate change

kn Resource managers need as much information as possible about Colorado River flows to make sustainable management decisions.

Staff Report

Resource managers grappling with the vexing question of how to allocate Colorado River water to the thirsty cities, ranches and farms of the Southwest have some new food for thought. A new U.S. Geological Survey study published this week in the journal Water Resources Research shows that more than half the streamflow in Upper Colorado River Basin originates as groundwater.

The information is especially important in the context of how climate change — through increased temperatures and evaporation, as well as changing precipitation patterns — will affect the river. One recent study, for example, showed that warmer spring temperatures are reducing flows independently of winter…

Alexander von Humboldt (1769-1859)

Humboldt’s Importance

Alexander von Humboldt was the most influential man of his age.  His contributions helped unify our understanding of nature and how human alterations could lead to dangerous changes.  Heads of government, scientists, engineers, artists, and authors were inspired by and consulted with him on a range of topics. Around the world, there are more cities, parks, mountains, and rivers named for Humboldt than anyone else that ever lived.

Humboldt’s strengths were his curiosity, his tireless desire to record his experiences, his ability to see connections, and his ability to write about objective facts with lyrical prose.  He described nature as a web of life, noting and mapping the plant and animal changes with elevation on Mount Chimborazo in Ecuador a century before C. Hart Merriam mapped life zones in central Arizona.  He invented isotherms, the lines on maps connecting areas of equal temperatures, and he warned that human destruction of nature was having widespread consequences.  He described the drop in stream flow, lake level, and general climate change resulting from cutting forests and diverting streams for monoculture farming.  Humboldt influenced and inspired Goethe, Darwin, Hooker, Bolivar, Thoreau, Muir, and many more.  Without Humboldt’s books, Darwin might never have gone to sea, South America might have remained a slave-holding Spanish colony for another century, and nature conservation might have lagged even farther behind human alteration of the land.

I am delighted to report that my grandson born in October, 2014 bears the name Alexander.  Alex’s birthplace is just 15 miles west of my home in Humboldt, AZ.

The essay introduced below provides links to some the books by and about Humboldt.  The one by Andrea Wulf is one of my all-time favorite biographical works.

Humboldt and Bonpland’s Essai sur la géographie des plantes and its significance

By: Randy Smith, Image Technician | Metadata Librarian. Peter H. Raven Library, Missouri Botanical Garden

“Over 210 years after Alexander von Humboldt and Aimé Bonpland’s work titled Essai sur la géographie des plantes was published, climate science, book conservation, and botanical research have converged around this 1805 work. This book was digitized and made available in 2008 by the Missouri Botanical Garden for the Biodiversity Heritage Library.

Modern science meets historic data

“In 2015, scientists published a paper detailing their findings as they retraced the path that Humboldt and Bonpland took on their ascent up the dormant volcano, Chimborazo, in Ecuador. The paper, “Strong upslope shifts in Chimborazo’s vegetation over two centuries since Humboldt,” utilized the data and map contained in Essai sur la géographie des plantes and presented modern data from the same locations as detailed in Essai to reveal the effects of climate change on the volcano.

“As Stephen T. Jackson writes in the 2009 book, Essay on the geography of plants, the significance of Humboldt and Bonpland’s work describing their ascent up Chimborazo lies in the detailed data they collected at various elevations. Jackson and historian Andrea Wulf have noted that while most people have forgotten Humboldt, his significance in unifying early scientific disciplines into an inter-connected web of life cannot be understated. Measurements taken on Chimborazo include light intensity, temperature, barometric pressure, and gravitational force. Descriptions of the flora and fauna at various levels of Chimborazo were described and illustrated on the map contained with Essai sur la géographie des plantes.”  Continue reading.

Saudi Arabia is out of water so it grows hay in Arizona

Outside of Phoenix, in the scorching Arizona desert, sits a farm that Saudi Arabia’s largest dairy uses to make hay for cows back home.

(Image:  NPR)

“That dairy company, named Almarai, bought the farm last year and has planted thousands of acres of groundwater-guzzling alfalfa to make that hay. Saudi Arabia can’t grow its own hay anymore because those crops drained its own ancient aquifer.
“The laws were put in place in the ’70s, and kudos to Arizona — they were really one of the first states to put in groundwater laws. But the laws were really designed for local or domestic farming. The idea that another country would come and essentially export your water via crops just wasn’t really around 30, 40 years ago. And so the laws that are in place are really inadequate for dealing with this new trend.

“This is occurring in a part of Arizona that is unregulated for groundwater. So there are no limits on how much water they can pump.”  From: www.dailykos.com

GR:  Not sure how long Arizona can afford to give water to the Middle East.  Perhaps this will continue until 1) the depth to water becomes so great, the Saudis will find desalinization of water for livestock feed is cheaper than pumping the water and shipping the hay, or 2), the ruling Saudis complete their move to the U. S. and simply abandon the poor people of their country.
