CITIES: Rebuilding the city-state

Cities may lead the way to a healthier future. Image: “Eiffel tower at dawn,” by Nitot. Image: wikimedia.

In a crisis, cities and states can react faster than countries. Boston, Chicago, Los Angeles, New York, San Francisco, and Seattle closed cinemas, gyms, bars and clubs; states like Massachusetts and California closed schools long before federal advisories. Closures to doors opened generous hearts: cafes near La Tour Eiffel gave away delicacies like foie gras and freshly baked bread, when Prime Minister Phillippe announced mandated a shutdown in Paris. Throughout history, city-states demonstrated a notably nimble organizational power: ancient Greek city-states like Cyrene, founded by climate migrants, created a new educational, scientific, and cultural center.  By 2050, 70% of the world’s people will live in cities. With the rise of megacities, with populations of 10 million plus, is it time for a new era of the city-state?

CITIES: Reuse and redesign

1.5 billion chopsticks are discarded every week. Could these elegant materials be repurposed? Japanese chopsticks. Image: wikimedia

Vancouver, Canada is taking reuse and redesign to an artistic new level. The many excellent restaurants serving cuisine with chopsticks cannot re-use these wooden implements. But ChopValue can. Collecting 350,000 chopsticks – every week – from Vancouver restaurants, the company cleans and repurposes the bamboo utensils to make tabletops and wooden kitchenware. It’s an idea that has potential far beyond Vancouver: worldwide 1.5 billion chopsticks are discarded every week. How it works: chopsticks are collected from restaurants and taken to local micro-factories where they are fashioned into home products. ChopValue was conceived over a sushi dinner when friends discussed the problem, and opportunity, of construction waste. Suddenly one said: what about chopsticks? Four years later, there are ChopValue programs in Canada and the United States. Will the land of Shinkansen, hosting the Tokyo Olympics, take up the torch during the 2020 Games?

WATER: Time and Tide in BOSTON

Boston, a port city, is threatened by rising seas. Map of Boston Harbor, wikimedia commons.

Coastal communities around the world are preparing for rising seas. Boston, a port city built on landfill, with a harbor renowned for freedom and liberty, is fighting a war. Last century, the Atlantic shore of Boston saw a persistent nine inch rise, with predictions that sea-rise may triple by 2030. By 2070? Look for three more feet of water. Boston ranks as the world’s eighth most vulnerable city, according to a study by the Organization for Economic Cooperation and Development of more than 100 coastal cities.

UMass Boston, waterfront campus, leads research on how to respond to coastal sea-rise. Image: wikimedia.

According to the University of Massachusetts Boston, and the Woods Hole Group, options to prevent the damage of flooding include spending $11.8 billion for a macro harbor barrier such as that built in the Netherlands. New York City is also studying the potential for a barrier that might cost $119 billion. In the short-term, Boston will budget $30 million per year to combat sea rise, with new ideas including:

TRANSPORT: New watertight doors on the rail tunnel near Fenway Park; redoing blockage of underground rail ventilation systems near Aquarium MBTA station.

PARKS: Protective berm of 10 feet along shore of Joe Moakley Park, a 60-acre oasis in South Boston near the beach. The park itself will be raised, and chambers installed beneath playing fields that will be capable of holding 5 million cubic feet of storm surge water. Other parks undergoing similar change: Ryan in Charleston on the Mystic River.

BUILDINGS: New condo high-rise housing on Boston Harbor comes with an “aqua fence” or portable flood barrier. General Electric (GE) leased two historic brick buildings, elevating the first floors and moving all electrical equipment to higher levels than the traditional basement.

MUSEUMS AND CULTURAL ICONS: Boston’s Children’s Museum redesigned a lawn into a hill, with a playground surrounded by dense plantings.

FOOD SUPPLY: Most large supermarkets build loading docks below ground; if food supply is to remain available when a city suffers flooding, relocating loading docks could improve public health.

MUNICIPAL PERMITS AND REGULATIONS: New buildings must meet increasing strict environmental standards. A similar approach governs new construction in Paris, France.

INVITING INNOVATIVE IDEAS: Boston’s Museum of Science, with the support of General Motors and Greentown Labs, is holding a $3,000 competition for ideas in transportation to help achieve carbon neutrality.

Boston’s Museum of Science is one of many educational design competitions; students worldwide may soon deposit capstones, and theses in an Idea Bank, and join Climate Conservation Corps service teams. Is your home community or school in a location vulnerable to sea-rise? What are you doing?  The best ideas are those that are shared.

WATER: Time and Tide

“Sunset on Manila Bay,” by photographer Bobbe21. Image: wikimedia.

Rising seas may seem far off in time. Although global oceans may rise 4 feet, some say it is tomorrow’s problem. But in Manila, Philippines and Jakarta, Indonesia – tomorrow is today. It’s also tomorrow in Miami and San Francisco.

Manila and Jakarta are both capitals of their countries; both were built as ports. Both have become mega cities: Manila with a population of 14 million, and Jakarta, 10 million. Both cities have been tapping underground water aquifers to quench the thirst of a growing populace, thereby draining the land to trigger subsidence. Jakarta is the fast-sinking city on earth. The government has decided relocate Indonesia’s capital to Borneo, a solution similar to that taken by Brazil when Brasilia became the new capital, or when Nigeria moved its capital from Lagos inland to Abuja. In those cases, sea rise was not the reason; rather, crowded ports, security, and a wish to represent the whole nation, especially the indigenous peoples residing in the country’s interior, were paramount. Now, rising seas may become the leading cause of coastal city rebuilding and relocation. Manila is already requiring people move from some sections so constantly flooded that children go to school via boat.

Golden Gate Bridge, San Francisco. Photographer: D. Ramey Logan. Image: wikimedia commons.

In the United States, 5 million people live within 4 feet of high tide levels. Factor in storm surges and flooding, and you can foresee where this is going. Miami, Florida and San Francisco, California are two cases in point. The choices facing both cities include building barriers to keep the sea out, such as the surge protectors of the Netherlands; restoring wetlands in seas and rivers such as those planted by Thames21, or even making people move, as in Manila. But pricey waterfront property near the Golden Gate Bridge is getting protection rather than relocation. The Bay Area approved a sea wall along the Embarcadero for $425 million. SFO airport is raising its sea wall at a cost of $587 million. In Miami, there are already frequent floods. More are coming: the Southwest Florida Climate Leadership Summit  of 2019 reported there will be 17 – 31 inches of sea rise by 2060. What will happen to all those waterfront condos? There’s new terms in developer’s lingo: “armoring” and “SLR” – sea level rise.

NASA developed space-based tools that measure the environmental impact of glacial melt to 293 port cities worldwide. Image: nasa.gov

Why are seas rising? Oceans absorb 90% of increased heat that is caused by emissions linked to human activity. Water expands as it heats, so the levels rise. Another climate-related cause, melting glaciers and icebergs. Coastal locations are set to generate $14 trillion in rebuilding by 2050. Innovations in city design, waterfront land and habitat, storm barriers, and new canal development will become leading fields in the next years. Tide is coming: do we have time?

CITIES: Trees

Boston’s Greenway. Image: Greenway Conservancy.

American cities lost 36 million trees in the last five years. Without trees, cities will get hotter and suffer more periods of air pollution. Why are we losing trees? Hurricanes and tornadoes tear them from the earth, fires burn them to the ground, insects and diseases weaken and kill trees. Those are some of the reasons we can’t easily control.

La Rambla, Barcelona, Spain. Image: wikimedia.

But there is one factor we can influence: city development. Cities are on the rise, rapidly growing into megacities with populations of 10 million or more. The United States, with 80% of the US population living in urban areas, especially in forested coastal regions along the West and East coasts, has a unique opportunity to preserve and enhance urban forests. It’s well worth it. Trees bring environmental and economic benefits.

URBAN TREES:

Provide shade for homes, schools, office buildings, cooling surface temperatures;

Reduce pollution through absorbing carbon and filtering pollutants from the air;

Reduce energy costs by reducing air-conditioning use – economics of $4 billion per year;

Improve water quality by filtering rainwater, absorbing nitrogen and phosphorus in to the ground;

Protect against urban flooding, absorbing surface water;

Reduce noise pollution by absorbing urban sound;

Enhance city soundscape by adding birdsong, and the whisper of wind through leaves;

Protect against UV radiation, absorbing 96% of ultraviolet radiation;

Improve health, physical through cleaner air and shade to exercise outdoors, mental health of being in nature;

Increase tourism and real estate values.

The New River passes through Bowes Park. Image: wikimedia.

Case studies of successful historic urban forestation reveal strategies. In the year 1600, so many people crossed London Bridge to live in the burgeoning London town that water supply became strained. One of the world’s first artificial or built rivers combined two elements: drinking water and trees. Constructed from 1605 to 1639, the New River stretches over 20 miles from Hertfordshire to Islington, just uphill from London, terminating in a water reservoir ready as needed. All along the route, tree-lined walking paths add protection and shade. Today, the New River is run by Thames Water PLC, managing water supply, and maintaining the walking paths traversed by urban hikers including the Ramblers Association. It is interesting to note that Hugh Myddleton, who partnered with King James I to build the New River, was the regent’s former jeweler and may be related to a member of the present House of Windsor.

Boston had a similar idea with Olmstead’s “Emerald Necklace” with recent Rose Fitzgerald Greenway extension of the urban breathing ribbon of green. The Greenway replaced what was formerly the Central Artery that ran traffic anthrough town; the road was placed underneath in a tunnel and the surface became a park. For an even earlier urban greening, some would point to the City of the Eiffel Tower where Haussmann widened tree-lined boulevards to breathe air and design into Paris. Presently, the city of light requires new commercial construction to have either solar or living green roofs.

“Terrasse panoramique @ Le Printemps Haussmann @ Paris.” by Guilhem Vellut, 2017. Image: wikimedia commons.

By 2050, 70% of the world’s people will live in cities. As cities grow, rebuilding better water systems, developing flood prevention plans, redesigning roads to accommodate electric and autonomous vehicles, how can trees become part of the plan? Will the proposed Climate Conservation Corps (CCC) plant trees in cities? A pilot project at Roger Williams University, or an initiative by World War Zero, might lead the way. There may be considerations of legal import: should trees have standing?

ENERGY: Building with the Sun

“August 31, 2012 Solar Corona CME.” Image: NASA Goddard Flight Center, wikimedia.

Heliogen: using solar to build the future. Solar roofs are not new: houses and office buildings often top with photovoltaic panels. Paris has decreed that new construction must have either a solar or green roof. Solar panels also are common in space. But until recently, it has not been possible to use solar technology to generate the extreme heat needed to produce building materials – cement, steel, glass. Heliogen, founded by CEO Bill Gross, backed by Patrick Soon-Shiong (physician and owner of the Los Angeles Times) and Bill Gates (Microsoft), uses artificial intelligence and mirrors to capture sunlight in such concentrations that high heat needed for industrial processes can now be generated by the sun. It’s clean, and the sun’s energy is free: both factors far outshine using fossil fuels for industrial construction that requires extremely high heat. In fact, Heliogen’s technology will be equivalent o 25% of the heat found on the surface of the sun itself. Building houses, schools, hospitals, and offices generates 20% of global emissions. Heliogen may soon go public, and is now seeking customers like cement companies who want what the company calls “green heat.”

CITIES Underwater – Venice

St. Mark’s, Venice, underwater again. “Aqua Alta Venise,” Image: wikimedia

Venice, UNESCO World Heritage Site, has suffered the worst flood in 50 years, attributed in its severity to climate change. Inside the city’s venerable buildings are paintings by Francesco Guardi, J.M.W.Turner, and many other priceless treasures. St. Mark’s Basilica, flooded just six times in nine centuries, shows inundation-damaged marble floors; there is fear the iconic columns may also be weakened. Modern art is also affected: Banksy’s “Shipwrecked Girl” mural on the Rio di Ca’Foscari canal is now underwater.

What can be done to prevent the loss of life, property, and infrastructure that cities like Venice must anticipate in the future? Coastal cities may soon have more accurate information about sea-rise. As Venice flooded in November 2019, Sentinel-6a entered testing in the final stage before expected launch in November 2020. Sea-rise is accelerating: five-year span 2014 – 2019 revealed a 4.8mm/year increase.  Copernicus Sentinel’s Jason-2 Poseidon Altimeters will map ocean floor peaks and valleys, reading temperature, salinity, gravity, currents and speed.

Coperniicus Sentinel-2A Satellite, 8 August 2017. “Greenland, wildfire.” Image: wikimedia commons.

A global system like COMSAT, Sentinel coordinates orbiting devices. Sentinel-6 moves between 66 degrees North and South; Sentinel-3 goes to 82 degrees. Sentinel-6 repeats its cycle every 10 days, monitoring big areas like the Gulf Stream or the Kuroshio Current; Sentinel-3 repeats every 27 days, focusing on smaller ocean eddies that move more slowly. Earth Science Division of NASA may link Landsat to Sentinel-2, completing the circle.

Meanwhile, Venice’s regional council may be having second thoughts about their recent veto to fund a proposal to combat climate change. Just minutes later, their Ferro Fini Palace offices flooded, sending the fleeing officials into the flooded streets, with  70% of Venice engulfed. From St. Mark’s Square, Venice’s mayor Brugnaro expressed hopes that the Mose system, a series of barriers consisting of mobile gates located at inlets, will soon protect the city from inundations. Venice is not alone: Boston and other cities may build harbor barrier systems. Worldwide, hundreds of cities  face the same fate: what are some of the ways cities can respond, from Amsterdam to Jakarta to Yangon?

CITIES: Welcome to the Club

“DJs at the club.” Photographer: Malagalabombonera, 2015. Image: wikimedia commons.

The wall fell down and so did a lot of other things on November 9, 1989. “No photos on the dance floor!” is an exhibition documenting Berlin’s club scene since the fall of the Wall. According to Felix Hoffmann, curator, “After the Berlin Wall fell in 1989, clubs, bars, galleries, and studios began popping up everywhere, filing empty buildings, factories; the club scene became the driving force behind the city’s rejuvenation.” Hoffman believes that Germany was first reunited on the dance floor. The city was not officially re-united administratively until October 1990; meanwhile, there were yet no rules. Pop-up parties met in forests, drawing together thousands of people who were formerly kept apart. Many believe clubs like Metropol and Tresor fostered a dance and music culture that all people, despite their former differences, discovered together.

In Cities of Destiny, Arnold Toynbee explored the idea that some cities, at moments in history, generate a climate of exceptional capabilities; example, Athens in the age of Pericles or Cyrene. New capital cities, from Baghdad to Brasilia, are built-visions of a nation, offering both governance and culture. In the future, climate change may cause some coastal capitals to move inland; as Indonesia moves the capital from Jakarta, due to sea-rise, what might exemplify the new vision? Dance clubs could be a factor, for another reason:

Floors that give light (and sometimes delight). “Break Dance” by Kalka, 2008. Image: wikimedia commons.

If dance brings us together, Pavegen’s idea does double step: floors that generate electricity when people dance, or walk, over special tiles. Pavegen demonstrated the innovation at the London Olympics when the West Ham Tube station lit itself from electricity generated by 2012 Olympic Games attendees as they arrived at the tube step nearest the stadium. It may not be surprising that Pavegen got their early start in dance clubs.

Be it dance clubs, or floors in schools, or even sidewalks in cities, why not build floors of the future that give light? Perhaps moving because of rising seas, there could be cities with streets paved in a new kind of gold, like the legendary El Dorado. Streets, walkways, sportsways, buildings, and dance clubs generating renewable just-in-time clean electricity may become the foundation for cities of the future.

CITIES: Forecasting the Future

“Canton Tower,” Guanzhou, China, one of the world’s cities most vulnerable to climate change. Image: wikimedia commons.

Cities are getting hotter, bigger, and more densely populated; it may be difficult for policy makers, and families, to keep pace with the environmental consequences of climate change, especially in urban areas that will house more than 70% of the world’s population by 2050. Like anything gradual, today doesn’t quite yet feel like tomorrow. Because the bicameral human brain works by comparison, a new app, using a method of climate-analog mapping, by Fitzlab shows what your city will feel like in the future:

Boston, Massachusetts = Rosedale, Maryland (Boston will be 7 degrees (F) warmer and 17% wetter;

Houston, Texas – Ciudad Mante, Mexico (Houston will be 4 degrees (F) warmer and 27% wetter.

“Boston: Back Bay.” Photographer: R. Shade, 2013. Image: wikimedia.

In general, most cities in North America will feel like areas 500 miles to their south. Globally, results of climate change on cities and surrounding regions will force more migrations, and cause a $54 trillion economic loss. Weather will wreak havoc; in 2017, 16 severe weather events in the USA caused  $306 billion in damage.

Rebuilding cities for resiliency in climate change will affect every country on earth, and perhaps seeing new capitals, and even new countries. Cities and capitals throughout history have been founded to inaugurate new visions: Abuja, new capital of Nigeria; Brasilia, new capital of Brazil; and Washington, D.C.,  founding capital of the USA. In the era of climate change, Indonesia may be considering moving the capital from Jakarta: like Abuja and Brasilia, the new capital will be more and less: more representative of the total population and less subject to rising seas. Rising seas may cause whole countries to move; Pacific Island nations are among those considering options. Every 1.5 degrees of Centigrade warming might cause 0.26 meters (0.85 feet) of sea rise. Every tenth of a degree exposes 10 million more people to possible migration due to flooding. Cities in most danger: Guangzhou, China; New Orleans, USA; New York City, USA; Mumbai, India; Osaka, Japan. Check your city on Resource Watch’s site.

ENERGY: AC – Hot trends/Cool news

“Air-Conditioners are everywhere” by Peteris, 2008. Image: wikimedia.

The hotter the climate gets, the more we turn on the AC (for the privileged who may have such access). Since 16 of the 17 warmest years have been since 2000, energy consumption by air-conditioning may triple by 2050, equaling the current electricity use of the European Union, Japan, and United States – combined. Enter SkyCool: a wafer-thin reflective material that radiates infrared, thermal energy at a very precise wavelength that slips quietly through Earth’s atmosphere, into space. Normally, heat energy is trapped in the atmosphere, so that’s very good news indeed.

But there’s more, and it’s cool news. The same infrared, thermal energy can be used to cool water moving through pipes to a just noticeable difference a few degrees cooler than, say, a school or an office building. That’s like AC, but better. While New Yorkers may be interested, many of the future customers will be in China, India, and Indonesia – expected to consume half of all the demand for air-conditioning in the future. China noted a 45% increase in the air-conditioner market in 2017. The new technology could reinvent air-conditioning and cool buildings, with greatly reduced emissions.

Hoover Dam used an ice-water system to cool concrete. “Hoover Dam at Night.” wikimedia commons.

There’s historic precedent: when the Hoover Dam was built, 3.25 million cubic yards of concrete were used; so much that a bucket of concrete went through the overhead cable delivery system every 78 seconds. But that much concrete would have taken 100 years to cool. Builders (a consortium called Six Companies included J.F. Shea Co.; MacDonald & Kahn; Morrison-Knudsen; Utah Construction; and a joint venture formed by W.A. Bechtel, Henry J. Kaiser, and Warren) devised a structural system of 582 miles of steel pipes within the concrete; they filled the pipes with ice-water, causing the concrete to cool and harden, and then they emptied the pipes of water but left the supporting structure to further strengthen the edifice.

Air-conditioning is a global market of $50 billion. Will the innovation, product of the TomKat Center for Sustainable Energy at Stanford University, change the future? Inventors Aaswath Raman, Eli Goldstein, (along with earlier team members) and Shanhui Fan are optimistic. Winner of the SXSW Eco Startup Showcase, the innovation is called SkyCool Systems,  Interested? Catch Aaswath Raman’s TED talk here.
