One ship 1,300 feet long (400 meters); 14 tug boats; 30,000 cubic meters of mud and sand cleared; 369 ships waiting in line behind the behemoth vessel: these are the elements that marked the reopening of the Suez Canal this week. When the Ever Given stopped traffic on 23 March, the Suez Canal Authority (SCA) estimated a $14 million revenue loss for each day of the blockage. Moreover, trade along the waterway that contributes 2% to Egypt’s GDP also stopped – costing $6.7 million per minute. (Russon 2021) Alianz insurer reported the Suez Canal March 2021 blockage cost between $6 billion and $10 billion.

Almost everything we touch has reached us, at some stage in the supply chain, via ship. Suez averages 106 container vessels and cruise ships per day. Trends in the container shipping industry reveal continuous pressure for size increase: since 1968, container ship capacity has increased 1,200%. (World Shipping Council, 2021) Why the pressure for bigger? One reason is because shipping is twice as energy efficient as rail and seven times more than vehicle. Shipping emits 3.1% of global CO2, but that percentage could rise as other industries decarbonize. The Energy Efficiency Design Index (EEDI) is a globally-binding design standard established by the International Maritime Organisation (IMO) to reduce climate damage caused by shipping: ships built from 2020-2024 will be required to improve energy efficiency by 15-20%, and by 30% after 2025. Many of those ships will transit the Suez Canal.

As container ships get bigger, canals will too. In 2015, Suez built a parallel waterway deepened by dredging one million cubic meters of sludge daily. Six companies did the work: Great Lakes Dredge and Dock Company (USA), Jan de Nul Group and Deme Group (Belgium), National Marine Dredging (UAE), Royal Boskalis Westminster and Van Oord (Netherlands). The Panama Canal, begun by Ferdinand de Lesseps but completed by the US, recently installed new locks on the Atlantic and Pacific sides that are 70 feet wider and 18 feet deeper than the originals. American ports like Baltimore, Charleston, Miami, Philadelphia, and Virginia have seen increased container traffic from the Panama expansion, according to the Supply Chain Management Program at MIT. The current US proposal “American Jobs Plan” allocates $42 billion for ports (air and sea) that may spur improvements.

Egypt’s famous waterway opened in 1869; 1.5 million people worked on the canal’s construction, evidence that infrastructure building creates jobs. Ferdinand de Lesseps, retired diplomat, visited his childhood friend now the khedive and viceroy of Egypt, in 1854 and gained concession to build the canal. Diplomacy remained a central value: the Suez contract Article VI states “tariffs of dues for passage…shall be always equal for all nations.” (Building the World, p. 193) To mark the inaugural opening of the Suez Canal, Giuseppe Verdi composed the opera Aida. Should the “American Jobs Plan,” aimed at rebuilding infrastructure, include funding for art?

Hearing (and Listening to) the Voices of the Future

Posted on December 15, 2019 by Building The World

Greta Thunberg: TIME Person of the Year 2019. Image: wikimedia

It is the world’s youth who must face consequences of decisions made now. Youth4Nature sent a COP25 delegation, and sailing across the Atlantic to get there, the world heard the message of Greta Thunberg, founder of Fridays for Future. Voices of youth may be louder than dicta of governments. UN Secretary General Guterres states: “The technologies that are necessary to make this possible are already available. Signals of hope are multiplying. Public option is waking up everywhere. Young people are showing remarkable leadership and mobilization. We need political will to put a price on carbon, political will to stop subsidies on fossil fuels, and start taxing pollution instead of people.”

Many macro achievements, throughout history, can be traced to the genius and innovation of youth. A 12-year old conceived of a canal joining the Atlantic Ocean with the Mediterranean Sea, the Canal des Deux Mers of France. Even younger, 10 year-old Ferdinand de Lesseps formed a friendship that would later turn into the Suez Canal. At COP25, it was the youth who insisted and persisted until a draft agreement on responses to climate change could be strengthened by contracts fulfilling promises made in Paris 2015. There is much to be agreed and achieved, including carbon contracts; now that debate awaits Glasgow. Meanwhile, it is hoped the world is not only hearing, but also listening to, the Voices of the Future, Greta Thunberg is TIME Person of the Year.

Earth (Day) Song

Posted on April 22, 2019April 20, 2019 by Building The World

Lil Dicky didn’t set out to make history, or even a song about the earth. At first, it was just an idea about animals with creatures voiced by a friends. But with friends like Ariana Grande, Justin Bieber, Wiz Khalifa, and Leonardo DiCaprio, a song for Earth Day was born. Honoring an occasion with music is not a new idea: the Suez Canal’s opening was celebrated with Verdi’s Aida. Philip Glass composed Itaipú to honor the hydroelectric facility that brings power to Brazil and Paraguay. Glass was inspired for the commission by the Atlanta Symphony Orchestra to write a work based on the original Guaraní name for the river’s sound: “Singing Stone.” Paul Winter attended a lecture by Roger Payne at Rockefeller University, hearing recorded songs of whales; with then-governor of California Jerry Brown, Winter helped found “Whale Day” and began making music with the troubadours of the deep. Carl Sagan included cetic songs in the compendium of music sent into space. On this Earth Day, what will you do to honor, celebrate, and save the Earth? Give a listen: Earth.

Building Peace

Posted on January 30, 2019April 18, 2019 by Building The World

Are ports the future of peace? There is precedent. An 1854 firman, signed by Pasha al-Said and Ferdinand de Lesseps, stated that a canal, to be built in Egypt, would be open to “all nations” and “no particular advantage can ever be stipulated for the exclusive benefit of one country” with tariffs equal for all nations. The Suez Canal opened in November 1869 with much fanfare including commissioning of Verdi’s opera “Aida.” In over 200 years, the canal was closed 6 times: the shortest was 3 days; the longest, 8 years. Despite such closures, the canal endeavored to follow the chartered guideline. How successful was the project that included openness and peace in its authorization and financing? On November 15, 2018, 33 vessels traversed from the North and 23 from the South. The building of the waterway employed 1.5 million people.

Almost two hundred years earlier, in 1666, the Canal des Deux Mers, or Canal Between the Seas, by the Edict of October 1666 for the Canal of Languedoc, was decreed and authorized to connect the Atlantic Ocean to the Mediterranean sea, in a waterway open to “all nations of the world as a great work of peace.”

Some call it Silk Road 2.0, but by any name, the Belt and Road Initiative, a system of canals, roads, trains, shipping routes and ports, when built, will be the world’s largest engineering project in history. This transport and connection system will include 1/3 of the world’s trade and GDP and 60% of the world’s population in 65 countries, using 75% of the world’s known energy reserves. Like Suez, or the Canal between the Seas, with open access essential to strategy and purpose, initiatives of such macro scope might include peace in their charter.

Mobilizing the Organization: Bringing Strategy to Life suggests four stages of mobilization: Purpose, Structure, Guidance, Resourcing. Guiding the Belt and Road Initiative will be eight International Centers of Excellence, focusing on climate change, environmental research, and disaster risk reduction.

Bangkok may lead the way. The first International Centre of Excellence on Integrated Climate Change, Disaster Risk and Environmental Research and Capacity Building opened in Thailand on 27 February 2018. It’s in partnership with Asian Institute of Technology, Geo-Information and Space Technology Development Agency (GISTDA), National Research Council of Thailand (NRCT), and Ramkhamhaeng University Center of Regional Climate Change and Renewable Energy (RU-CORE). When Professor GUO Huadong, Chair of DBAR (Digital Belt and Road) signed a Memorandum of Understanding with NRCT Secretary-General Sirirung Songsivilai, the agreement chartered the Center in Bangkok (ICoE-Bangkok) to create a satellite database for “environmental protection, risk reduction, food stability, urban development, and the preservation of coastal resources and world heritage sites.” The Suez Canal linked banking and peace; recent studies have suggested that banking may be one of the keys to chartering and maintaining peace. Guiding factors regarding resources – financial, natural, and human – Thailand might help to build the future, opening a portal of peace.

Decade of Decision

Posted on November 9, 2018November 3, 2018 by Building The World

Decisions made in the next decade may shape the future. In 2020, the United States will hold an important election; Japan will host the Olympics. All eyes on the future. Species, both animal and plant, are disappearing 1,000 times faster than before humans appeared. Earth is threatened by climate change; water is becoming more scarce; and, as Hansjorg Wyss states: “extractive industries chew further into the wild.” Wyss believes there may be an answer: conserve remaining wild lands as public reserves. The world’s first national park (Yellowstone in 1872) opened a new idea of preservation: now, 15% of earth’s land and 7% of the oceans is protected. Wilderness tamed and framed like the National Trails System; greenways like that on Boston’s Central Artery as nature ribboning through cities; rivers granted personhood rights are among the regulatory and legal measures of protection. Edward O Wilson, founder of Half-Earth Day, warns we must preserve half the earth to save the whole. Timing may be urgent: 77% of land on earth has been modified by humans. Wyss pledged $1 billion over the next decade with the goal of protecting 30% of the planet by 2030.When the United Nations Biodiversity Conference convenes in land of the Suez Canal on November 13, 190 countries will seek agreement to preserve the natural systems that support the earth. Here’s a link to include your voice.

Water Day: Wear Blue

Posted on March 22, 2018 by Building The World

World Water Day: March 22, 2018. We’re an increasingly thirsty world: by 2050, one-third of the planet will suffer water scarcity. Climate change intensifies problems: floods and drought are worse. More than 3 billion people suffer diminished access to water for at least one month each year due to drought: that number is set to increase by 2050 to 5 billion. Mitigating influences of forests and wetlands are vanishing: two-thirds have been cut or built upon since 1900, according to a study released by the United Nations. Rivers are polluted, with ten rivers identified as the major source of marine plastic debris. Think those problems are “elsewhere” and you may be alarmed to find 80% of tap water contains microplastics. What can you do, as an individual? Social scientists observe the original days of the week had a dedicatory purpose, still detectable in the names. For example, the Japanese day Suiyōbi is Wednesday, meaning Water Day. Should we rededicate the days of the week to raise awareness of our shared resources, including water? One fashion leader suggests wearing blue as a way to honor water. Would you consider dedicating one day each week to water?

Canals: building the future

Posted on September 30, 2017October 12, 2017 by Building The World

Caño Martín Peña may offer a vision for the future. Help Puerto Rico now. Image: wikipedia.

Caño Martín Peña stretches 3.75 miles linking wetlands and canals to rivers meeting the sea of San Juan Bay, Puerto Rico. In 2004, eight communities along the canal incorporated to protect the canal, and dredge the channel; in 2015, the Environmental Protection Agency and the Urban Waters Federal Partnership issued a nueva vida – new life- vision for the canal. Rebuilding Puerto Rico, after recent hurricane destruction, may increase awareness of canals in flood mitigation. According to Inland Waterways International, canals create economic and environmental benefits, as well as locally-generated electric power. The World Canal Cities Organization recently met in Shaobo, China to explore the Grand Canal, busiest in the world, and building block of the Belt and Road Initiative. Panama and Suez are also notable. The Erie Canal opened the United States to a new era of development; the New York Canal Corporation worked with the World Canals Conference to host the 2017 conference on the Erie Canal in Syracuse, New York. What should the future hold for the world’s canals? How might Puerto Rico lead the way? Enlace and the Caño Martín Peña Ecosystem Restoration Project aim to improve 6,600 acres of the San Juan Bay, and the lives of those near its waters. In the future, canals may help coastal cities weather rising seas, allowing the water in as in Rotterdam. Meanwhile, Puerto Rico looks for help now, and leadership in the future, perhaps including a new vision of canals.

World oceans may be the deep frontier; we have explored just 5% of the seas that give name to the water planet. Great cities were built for ocean access: Amsterdam, port of the Netherlands; Singapore, hub of the trade winds; New York, joined inland by the Erie Canal, celebrating its 200th anniversary. Other ocean to inland waterways include the Grand Canal of China, the world’s longest; Suez and Panama, both led by Ferdinand de Lessups. Will the Channel Tunnel inspire a TransAtlantic Hyperloop? Ocean Portal, by the Smithsonian National Museum of Natural History, offers educational resources for teachers and students. June 8 marks World Oceans Day, when over 100 countries honor, and protect, our oceans.

Earth Day. Could the answer to our planet’s energy problems and resultant climate change be found by looking up? Every culture on earth has myths about the sun. For example, Egypt worshipped Ra, the sun god whose falcon head was crowned with a solar disk. In 1973, building upon the success of COMSAT and the Apollo Moon Landing, Peter Glaser was awarded the United States patent for solar power from space, via satellite. Honored in the spring, as the sky glows with a stronger light, Earth Day might call us to look up.

Why is an Orange like a Light Bulb?

Posted on April 14, 2017April 22, 2017 by Building The World

Did you know that growing one orange requires 13.8 gallons of water? Next time you crunch into an almond, you’ll consume the result of one gallon. California grows both: a result, in part, of the Colorado River Compact. Edward Spang of the University of California Davis, as well as colleagues including David H. Marks of MIT, predict competition for water use will increase in the water-energy-food nexus. Spang developed a water consumption for energy production (WCEP) indicator, comparing the use of water for different forms of energy in over 150 countries. Fossil fuels and biofuels require the most water; wind is less thirsty. The United Nations cites the World Water Development Report: “If water, energy, and food security are to be simultaneously achieved, decision-makers, including those responsible for only a single sector, need to consider broader influences and cross-sectoral impacts. A nexus approach is needed.”
