WATER: Is the Drought OVER?

Posted on by Building The World
Droughts and floods will continue. Now we can predict them with GRACE. Image: “GRACE globe animation” by NASA. Public Domain, included with appreciation.

Atmospheric rivers: 11. Snow: 55 feet (16.76 meters). Rainfall: thus far in 2023, more than all of 2022. Conservation mandates and restrictions: eased. Outdoor watering: again permitted. Reservoirs: many refilled. Is California’s drought officially over? Conditions are better, but concerns remain. The issues are not restricted to California, but the state serves as a case example.

While 2023 brought relief and refilled many California reservoirs, drought is cyclical. Image: “Drought area in California” graphic by Phoenix7777, based on U.S. Drought Monitor Data. Creative Commons 4.0. Include with appreciation.

GROUNDWATER – On the surface, things certainly look better. But California’s underground aquifers are still in trouble, some at lowest levels ever recorded. After previous droughts (2007-2009, 2012-2016), California’s groundwater in the agriculturally important Central Valley recovered only 34% (2007-2009 drought) to as little as 19% (2012-2016). During drought periods, groundwater supplied 60% of California’s water, so maintaining underground aquifers is critical.

In irrigated agricultural regions with limited surface water supply, drought can have severe effects on groundwater. Recent innovations for storing floodwater underground in “water-capturing basins” hold promise. What kinds of future innovations will collect rain and flood water for future use? The Sustainable Groundwater Management Act (SGMA), passed in 2014, requires local agencies to form and fund groundwater sustainability agencies for high priority areas to control overuse of water by 2034. The United Nations raised awareness of the importance of groundwater by dedicating World Water Day 2022 to that resource with the motto: “Making the Invisible Visible.”

California obtains a portion of its water from the Colorado River. Image: “Colorado River at Horseshoe Bend” by Charles Wang, 2023. Creative Commons 4.0. Included with appreciation.

COLORADO RIVER – Surface water and underground aquifers are not the only sources. Water supplies from the Colorado River flow, at some distance, to cities and towns in Southern California. That river is still suffering through a two decade long drought that depleted reservoirs like Lake Powell and Lake Mead. Seven states, as well as many indigenous sovereign nations and also Mexico, share in the water according to rules set in the Colorado River Compact 0f 1922. If the seven states cannot come to agreement on water usage cutbacks, the federal government will step in. In April 2023, the U.S. Department of Interior’s Bureau of Reclamation introduced options.

FUTURE  OF WATER– Satellite data confirm what we know all too well when 12 inches of rain in one day sweep through Ft. Lauderdale, Florida closing schools and highways, or floods drench Sindh Province, Pakistan,dislocating millions of people. We know and feel it when drought plagues land, dries up agricultural fields, drains reservoirs, and threatens hydroelectric facilities like those on the Po River of Italy, or  Snowy Mountains Hydroelectric of Australia or Hoover Dam of the Colorado River in the United States.

Hydroelectricity depends upon abundant water. Drought has threatened energy production on the Colorado River’s Hoover Dam. Image: “Hoover Dam” by photographer Ansel Adams, 1941. Public Domain, National Archives and Records Administration image #519837. Included with appreciation.

Hydroelectric power plants on rivers throughout the world are subject to changing water levels. If a river suffers drought, some hydroelectric facilities must be switched off. A recent study sounded the alarm. By 2050, 61% of all hydropower dams will be at high risk.

It takes two – GRACE and GRACE-FO. Image: “Gravity anomalies on Earth” by NASA, 2012. Public Domain. Included with appreciation.

Climate change will make rains more intense and droughts more frequent. The Gravity Recovery and Climate Experiment satellite duo, known as GRACE and GRACE-FO will reveal a big picture in a long view. Dr. Matthew Rodell, Deputy Director for Hydrosphere, Biosphere, and Geophysics, Earth Sciences Division, NASA, and Dr. Bailing Li, of Goddard’s Hydrological Sciences Laboratory, led a team that studied over 1,000 weather events during the period 2002-2021. Rainfall extremes were noted in sub-Saharan Africa, North America, and Australia. Intense droughts were seen in South America, the United States, and elsewhere. Droughts outnumbered rain events by 10%.  It’s costly: 20% of the USA’s annual economic loses were due to floods and droughts. Is there a solution? Using floodwater to recharge aquifers and irrigate agricultural land will be an area of innovation.

Water Futures Index – is water a trading commodity or a human right? Image: “Nasdaq” by xurde, 2007. Creative commons 2.0. Included with appreciation.

WATER FUTURES –  Another development? Water Futures trading contracts such as the Veles California Water Index (NQH20) that launched on NASDAQ in 2018. Prices have fluctuated from below $300 per AF (acre-foot which equals 325,851 gallons or 1,233,480 liters) to 18 August 2022’s price of $1,134. At today’s post date, the price is $855. Is water a commodity or a right? Some say that commodity trading makes it possible for those who use quantities of water to plan, and plant, with more certainty.

WATER RIGHTS – But others might question water trading. On 28 July 2010, the United Nations General Assembly passed Resolution 64/292 that recognizes water and sanitation as a human right. In 2022, the Committee on Economic, Social and Cultural Rights adopted General Comment No. 15, with Article 1.1 stating “The human right to water is indispensable for leading a life in human dignity. It is a prerequisite for the realization of other human rights.” Some would say that the right to sustainable, healthy water goes beyond human rights. New Zealand’s Whanganui River recently received personhood legal status, granting the river its own rights.

CITIES: Floating into the Future

Posted on by Building The World
Floating cities have long captured our imaginations, and may become a reality with sea level rise. Image: “Sky City in Flash Gordon Serial” 1936. Public Domain Creative Commons. Included with appreciation.

Sea level rise is coming – how much depends upon the extent of melting glaciers and coastal inundations. Coasts often harbor cities: the earliest urban centers developed because of sea access. By 2050, 68% of the world will live in cities, many of them ports. How can coastal cities prepare for sea level rise? The Netherlands has long led the world in city design for low-lying coastal areas. Now, many cities are considering preparation for rising seas. Here are some examples.

Seoul is building floating sections of the city. Image: “Seoul at Night,” by traveloriented, 2014. Creative Commons 2.0. Included with appreciation.

Seoul announced plans for a floating public swimming pool and art pier space, featuring a concert hall and a marina. Designed for Inchon Han River Park, the 5,000 square meters development will feature the Han River by floating upon its coastal waters.  Seoul Mayor Oh Se-hoon announced the budget of $30 million (30 billion won).

Copenhagen inspired Seoul’s Mayor Oh, who announced Seoul’s new vision while visiting the Danish capital’s Harbour Bath. Denmark also built Havnebadet Islands Brygge, a floating public swimming pool that opened in 2003. Copenhagen worked on another project with Bjarke Ingels Group to build “Urban Rigger,” a floating residential district.

New York suffered damage and flooding during Hurricane Sandy, leading to a proposal to rebuild the Big U of Lower Manhattan.

New York suffered $19 billion in damage after Hurricane Sandy (2012). A new city design for lower Manhattan followed. Bjarke Ingels Group (BIG) is presently developing a future vision for New York City. The BIG U proposes a protective system around the area of Manhattan from West 57th Street, down to the Battery, and then up again to East 42nd Street. The area is vulnerable to sea level rise. New York may consider options for aquatic construction as well as protective barriers. Will Wall Street soon float more than bonds and floating rate funds?

WATER: Colorado River and the Future

And it’s only gotten worse since: 2023 is a critical year to determine the future of the Colorado River. Image: “Drought: before and after.” Photo, United States National Park Service. Wikimedia creative commons public domain. Included with appreciation.

Sharing water is one of the oldest bonds of community. Ancient villages centered around the well; urban settlements like Rome were built near rivers; great cities and civilizations began as ports.

“Rome: A view of the river Tiber looking south with the Castel Sant’Angelo and Saint Peter’s Basilica beyond” by Rudolf Wiegmann, 1834. Wikimedia, public domain. Included with appreciation.

But when neighboring communities are seven large states, the water is the Colorado River, and drought conditions are straining resources: sharing is proving difficult. Camille Touton, Commissioner of the US Bureau of Reclamation, official manager of the river, recently ordered Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming to cut 1/3rd of their water usage. Encouraging states to figure it out amicably, Touton warned that if no solution were soon agreed, the federal government would settle the score. The matter is urgent: the Colorado River provides water for drinking and irrigation for 40 million people. Moreover, if Colorado River reservoirs Lake Mead and Lake Powell reach ‘dead pool’ the Hoover Dam will not supply electricity.

The Law of the River, a 100-year compendium of laws regulating the Colorado River from inception of the Compact in 1922 to 2022 (and now continuing), is both history and future. As farmers claimed more water to grow food to feed a nation, and as cities like Los Angeles and Las Vegas burgeoned in population, dueling needs competed for resources. Add drought and the arguments became more heated.

The Colorado River will affect water policy in the United States, Compact partners of Mexico and the original American Sovereign Nations, but around the world. One third of all the rivers and lakes globally are facing drought. Rivers like the Amazon, Indus, Nile, Po, Rhine, and Yangtze, among others, will debate similar decisions.

ENERGY: Rare Earths

Posted on by Building The World
Rare earth elements are needed to power smartphones, and many other technologies. Image: “Foldable smartphones” by Ka Kit Pang. Wikimedia creative commons 3.0. Included with appreciation.

Smart phones are common but so-called “earths” that power these devices are rare. In fact, 17 elements termed rare earth elements or REEs supply everything from phones to electric vehicles, wind turbines, and military systems. That glowing light on your car dashboard? Rare earth chemistry in action.

“Rare earth oxides” by photographer, Peggy Greb. United States Department of Agriculture. Public Domain. Wikimedia. Included with appreciation.

Rare earths are obtained by mining, combined with extraction processing, because these oxides are not found in neat deposits but rather mixed in with other elements. REE mining is a specialty sector. China, land of the Grand Canal, is currently the world leader: both in mining and extracting, controlling 60% of the market. Recently innovations in rare earth element recycling could promote reuse and reduce mining.

“Rare earth oxides production graph” by D.J. Cordier, Haxel, et al., United States Geological Survey, 2013. Wikimedia. Public Domain. Included with appreciation.

Most rare earth elements used in Europe are imported. But, recently, mining company LKAB found more than one million tons of rare earth oxides in the far northern area of Kiruna. Sweden will have a ready market. However, it will be at least a decade before permitting, mining, and processing will reach European smart devices.

Sámi land and water resources are involved in rare earth mining. Image: “Three Sámi women” circa 1890. Wikimedia, public domain. Included with appreciation.

Sweden will have a nearby partner: the Northvolt battery factory is in development. Also in Sweden’s north: projects for green steel. Meanwhile, LKAB has been busy: in order to reach the deposit, the entire town of Kiruna had to be moved. There is also consideration of the Sámi people of northern Scandinavia who herd reindeer over the lands of Finland, Norway, Sweden, and the Kola Peninsula of what is now Russia, these are lands to which the Sámi have indigenous rights. Sámi once transported mined ore via reindeer to deliver material to the coast for shipping. A “cultivation line” was established by law to project Sámi herding lands, but conflicts and differences remain.

“Perite” by photographer David Hospital, wikimedia creative commons 3.0. The mineral is named after Per Adolf Geijer. Image included with appreciation.

Sweden’s newly discovered deposit now has a name: Per Geijer. It’s an homage to Per Adolf Geijer (1886-1976), Swedish geologist who also has a mineral, discovered in Sweden, named after him: perite.

The rare earth element market is expected to grow, estimated to be worth $9.6 billion by 2026. In the midst of this acceleration, mining rare earth elements can affect soil and groundwater, creating acidic conditions. How can rights to rare earth elements be protected, explored, and – when mined – shared? How should land and groundwater affected by rare earth mining be restored and renewed?

Welcome, Year of the Water Rabbit. Seasons may give us the year, but the moon tells us when the year is new. Amidst feasts and fireworks, this year’s water rabbit may also bring scientific good tidings. Did you know that Chinese tradition places a rabbit on the moon? And now that rabbit may have discovered lunar water.

An ancient myth tells of Chang’e spirited from Earth to the Moon in a lovers’ tangled tale. She became the Moon goddess. But even a goddess can become lonely, so she was allowed to have a pet: a rabbit. Chang’e and her pet rabbit Yutu entered space lore when NASA’s Apollo 11 crew exchanged banter with Houston Mission Control just before the lunar landing in 1969, as the astronauts promised to look for the two lunar mythic figures. When China sent its first lunar probe to the moon in 2007, it was named Chang’e-1: its little robotic rover was name Yutu – Jade Rabbit. Chang’e was just getting started: in 2022, Chang’e-5 and its rover Yutu discovered evidence of water on the moon.

Water on the moon is a big discovery. Water is necessary for human habitation: carrying needed water into space would severely limit stays. Water could encourage space agriculture: one can consume, and carry, only so much tubular food. Finally, water – yielding hydrogen – might provide rocket fuel. Processing lunar water will be a technical challenge, but having water to start with is essential. Thanks to Chang’e – moon goddess – and Yutu, the Water Rabbit (among other space missions globally), human exploration may open wider, and longer, horizons.

Back on Earth, Year of the Water Rabbit opens a holiday with a long tradition. In China, as early as the 14th century bce, astronomers began to track solar longitude and lunar phases, forming the basis for a scientific yearly cycle. In China, around the time when the Grand Canal began to take shape, the Shang Dynasty (1600-1046 bce) initiated the tradition of honoring the new year. The following Zhou Dynasty (1046-256 bce) continued the custom, now turning its purpose to wishes for a good harvest in the soon-to-come spring. But it was not until the Han Dynasty (202 bce – 220 ce) that a method for determining the date was added, and families began to plan gatherings to feast and celebrate. The ancient lunar calendar was replaced in 1912 by the common, so-called Gregorian, calendar, but by 1949, popular practice prevailed and a public holiday period was renamed “Spring Festival” but is still called by many, Lunar New Year. Across Asia, and around the world, festivities feature feasting by sharing “longevity noodles.”

Noodles are a Lunar New Year culinary tradition. “New Year Prosperity Toss,” by photographer Jayden Teo, 2020. Creative commons 4.0. Included with appreciation.

How did the Lunar New Year or Spring Festival tradition become associated with animals? The origins of the practice are shrouded in ancient history, but some folk legends exist. Naming years after animals is surely more poetic and interesting than sequential numbering. Around the first century ce, the zodiac menagerie was grafted onto a 12-year cycle repeating within a 60-year system. Within that system, animals dance through the elements of water, wood, fire, earth, and metal. Behold 2023: Year of the Water Rabbit.

WATER: Glitter Litter – Getting Better

Posted on by Building The World
Holidays invite sequins and sparkle. Image by Irson Kudikove, 2010. Public domain wikimedia. Included with appreciation.

Holidays like New Year’s Eve invite festive attire, often sparkling from head to toe. The origin of sequins reaches back to ancient gold coins, worn by the wealthy for special occasions. In fact, the word “sequin” comes from the Italian “zecchino” referring to the gold coins minted in Venice, and before than from the Arabic “sikka” meaning a minted coin. One may still see some coin-bedecked costumes in certain forms of dance. No wonder sequins are now associated with lavish occasions.

But now we manufacture a very different kind of sequin for dress-up attire. Did you know that most sequins and glitter are themselves dressed? They are coated with reflective plastic that produces the desired shine. Such glitter quickly turns to litter. On the dance floor, tiny sequins shake loose. In dramatic hair styling, glitter sprinkles the comb and later washes into the shower – and the water supply. Unlike some plastics that are carefully monitored for dangerous chemicals and strictly regulated for recyclability, fashion sequins and glitter are not subject to such rules: in fact, most contain toxins.

Steppin’ Out in Style? Try algae. Image: “Sequined Shoe” by sunshinecity. Wikimedia. Included with appreciation.

So, is there a sustainable way to sparkle? Yes!

First responsibility is with designers and garment manufacturers:

Elissa Brunato introduced an innovation: Bio Iridescent Sequins made of biodegradable cellulose. Working with RISE Research Institute of Sweden’s material scientists Hjalmar Granberg and Tiffany Abitbol, Brunato found a tree-based cellulose that contains a natural polymer structure reflecting light. The production process involves pouring natural liquid cellulose into a mold to which colors can be added. From the city of London Bridge, designers like Brunato, and Stella McCartney, are among those building a different kind of bridge – through the Future Materials Bank.

Phillip Lim and Charlotte McCurdy produce marine micro algae to form a natural sequin. Introducing a petroleum-free sequin dress made with bio-plastic sequins formed from algae, Lim and McCurdy work with One X One by Slow Factory to create carbon-neutral materials for fashion. Circular fashion is a term often heard: here, algae form the material that later return to the earth, biodegrading to nourish the planet. Lim found inspiration in pearls and crystals, sparkles and shines of nature, and now finds nature the source of fashionable sparkle.

Anuje Farhung, founder of the fashion brand House of Farhung, offers couture in Pakistan and globally with luxury, formal, and bridal fashions. Farhung studied at Savannah College of Art and Design in Georgia, USA, and worked with fashion house Oscar De La Renta before founding her label offering sustainable sparkle. When Anuje collaborated, in 2020, with Sarah Khan from the National Centre of Excellent in Geology at the University of Peshawar, they selected red algae for their source of luminous fashion.

Second responsibility is with the consumer. While 40% of shoppers surveyed by Oxfam said they’d purchase glittering clothing for the holidays, most confessed they would wear it only a few times. As many as 1.7 million items of sparkling clothing end up in landfills each year. Once in the landfill, sequins and glitter tend to dissolve into a toxic ooze called “landfill leachate.”

Avoid landfill leachate – glitter responsibly. Image: “Glitter Slime” by Slime 123 Globex” by Barbara Rayman, 2017. CC4.0 Wikimedia. Included with appreciation.

As you plan for New Year celebrations, or perhaps a coming party, prom, wedding, or special occasion, if garment manufacturers offered sequins and sparkle at a price slightly higher but much more sustainable, would you purchase glitter that doesn’t litter?

WATER: Armies, Veterans, and Peace

Posted on by Building The World
Veterans Day, a Call to Peace. “Veterans Day Poster, 1987.” Wikimedia. Included with appreciation.

Today is Veterans Day, observed in the United States on November 11 since 1919, and founded to commemorate the 11th hour of the 11th day of the 11th month (in 1918) when an Armistice ended World War I. Soon thereafter, the Paris Peace Conference resulted in the Treaty of Versailles. In 1954, Armistice Day was renamed Veterans Day. While today honors those who serve in readiness for war, the origin of the holiday is peace.

What is the role of armies in peace? During times of peace, the Roman Army built roads that connected Italy and beyond, and deployed military squadrons to explore and then build the Roman Aqueducts to bring fresh water to the central city. The Netherlands instituted Dike Armies in 1319 to respond to water emergencies.

Water emergencies are still with us today, perhaps more than ever. The Colorado River, bringing water and electricity to 1 in 10 Americans, as well as agriculture and industry, is 19% smaller than in 2000; reservoirs Lake Mead and Lake Powell are severely depleted. Hydroelectricity, produced by Hoover Dam’s harnessing of the Colorado River, is threatened by drought. The Mississippi River suffers concerning depletion. The same is true for many rivers around the world.  Rights of Rivers deserve protection. Who will defend them?

Water problems are causing drought and also inundation. Recent torrents from Hurricane Ian devastated Florida, caused loss of life and property damage totaling in the billions. Areas hit by increasingly powerful floods and storms need rebuilding. Who will do this? How can we best respond to climate damage, or build protection?

History offers an inspiration to uphold military expertise, service, and tradition. We might save our coasts by a modern day equivalent of the Dike Army. We can follow the productive example of the Roman army in sustaining the Colorado River and other threatened water sources.  Armies, and veterans, might serve in what William James called the “Moral Equivalent of War” – defending Nature and Peace.

WATER: Floods and Helping Hands

Posted on by Building The World

Recent floods in Florida in the United States, and in the Sindh province of Pakistan, caused loss of life, property, and long-term displacement. Because we are the water planet, climate change will first be felt through water. This is true of the past summer’s droughts, reductions in the Colorado River and Lake Mead, heatwaves, and wildfires; now it is true of autumnal seasonal storms intensified by melting glaciers in Pakistan and warming oceans near Florida. If you are reading this post, it is because you are fortunate to have power and electricity. Many do not. If you would like to extend a helping hand, here are some suggestions:

Pakistan  – flood relief and rebuilding efforts may be helped by outreach, including sources like the Edhi Foundation, headquartered in Karachi, that provides emergency assistance across Pakistan and internationally. Edhi Foundation’s Flood Relief Campaign may be reached via: https://edhi.org. Another option is Islamic Relief USA: https://irusa.org.

“Hurricane Ian reaches Florida, USA” NASA, Earth Observatory, 2022. Image in the public domain, included with appreciation.

USA – inundations from Hurricane Ian, a category 4 storm with winds of 150 mph, damaged areas of Florida including Captiva and Sanibel, Naples and Fort Meyers. Two million residents are without electricity and running water. The storm is now moving towards South Carolina, Georgia, and North Carolina.  You can volunteer or donate to the American Red Cross via https://www.redcross.org. Another option is Caring for Others at https://caring4others.org.

As climate change continues to cause damage, we may need to respond in two ways: disaster response and proactive renewal. Is it time to consider a Climate Conservation Corps, combining active service and education? Some have suggested an organizational name, and membership term, of CliMates. What do you think of this idea?

Thanks to those who kindly suggested organizations for helping those affected by recent floods.

WATER/ENERGY: Hydroelectricity – What is the Future?

Posted on by Building The World
Lake Mead is shrinking through prolonged drought. That will affect hydroelectricity generated by the Hoover Dam. Image: “A Comparison of Lake Mead 2000 and 2015,” by Joshua Stevens, NASA Earth Observatory, using Landsat data from U.S. Geological Survey. Image from the Public Domain: wikimedia and nasa.gov. Included with appreciation.

Drought affecting the Colorado River, and resultant depletion of reservoirs Lake Mead and Lake Powell, may soon bring about Tier 2 shortage conditions. When Lake Mead’s water level falls below 1,050 feet above sea level, the new normal will reduce water allotments for Arizona, Nevada, and Mexico. Arizona will face a 21% reduction. Lake Mead’s drought is so big that is it now visible from space. Water for drinking, agricultural irrigation, and industry will be affected.

Will water continue to course through the Hoover Dam’s jet-flow gates? “View of Hoover Dam with jet-flow gates open,” by U.S. Bureau of Reclamation, 1998. Public Domain image. Creative Commons, wikimedia. Included with appreciation.

But there may be more consequences. The Colorado River, down 40% from 2021, flows through the Hoover Dam, generating electricity. If Lake Mead’s water recedes below 1,000 feet (just 50 feet above Tier 2 danger level), “dead pool” will happen, meaning water cannot flow downstream to power the dam. The Hoover Dam supplies electricity to Arizona, California, and Nevada. Western parts of the United States have suffered a prolonged drought; hydropower has dropped to 14% below its 10-year average.

Hydroelectric power is also threatened in other locations around the world. Italy recently suffered electricity reductions due to drought on the Po River. India and Pakistan share water usage, including hydroelectric access, under the terms of the Indus Waters Treaty; eight new hydropower plants have just been approved.

The Murray River of Australia, key to Snowy Mountains Hydroelectric, is now seriously affected by drought; water for drinking, agriculture, and electricity may be threatened. Brazil’s water flows into hydro dams reached a 90 year low, affecting facilities including Itaipú. The alternatives, when hydro fails to produce, may include greater reliance on fossil fuels. Many are concerned about that direction.

The Indus River may add eight new hydropower plants. Image: “Indus River near Skardu, Pakistan,” by Kogo, 2004. GFDL Public Domain, wikimedia. Included with appreciation.

In a world of climate change, increasing droughts may lead to a rethinking of hydroelectric power which, in 2020, generated 1/6th of the world’s electricity. Hydroelectric facilities can be found in 150 countries, with China the largest producer. Global investment in hydroelectricity is significant, and growing; will it be a wise investment?

Hydroelectric Power has a low carbon footprint, and is valuable in a time of climate change. Illustration: “Carbon Emissions by Electricity Source,” by Vattenfall and Japan’s Central Research Institution for the Electric Power Industry, 1999. Image in the public domain, wikimedia. Included with appreciation.

Hydropower is low-carbon electricity, a property valuable in a world trying to limit carbon emissions. Hydropower is also continuous, an important factor to balance intermittency of renewables like solar or wind. The future of hydroelectric power is linked to the future of water. How will recent funding of climate preservation and protection support water sustainability? Will water innovations help harness the power of water to power the future?
