Valentine’s Day celebrates love in all its many wonderful forms and cultural traditions. But the greatest lover of record, according to DNA, might be Genghis Khan. According to DNA tracing, over 16 million people are related to the legendary Mogul emperor whose dynasty helped to renovate, repair, and advance China’s Grand Canal.
“Ghengis Khan” from 14th century painting, public domain.
Kublai Khan, Genghis’ nephew, when he became emperor, directed grain be moved northward to the new capital the dynasty had established: Dadu. Khan commanded that 816,000 tons of grain annually, with the major share – 537,000 tones – coming from the south, be delivered to the new capital. But when the supply arrived from the Yangtze region by the canal, it still had to be transported 20 miles (32 kilometers) further to reach Dadu. To accomplish this task, draft animals were conscripted, leaving farmers without adequate help: agriculture suffered. Kublai Khan saw the problem and ordered the Grand Canal’s seventh section to be completed, straightening and improving the entire route during construction of the final leg. Once the water highway was complete, communications between and among all parts of the empire could reach the capital, as well as the grain. Some say the Grand Canal transformed a region into a nation. Today, we know Dadu as Beijing.

Kublai Khan’s uncle Genghis fathered five daughters and four sons with his primary wife Börte, and as many as 500 secondary spouses. Known as a master of conquest, Genghis Khan, 13h century warrior and ruler, left his mark on civilization, and with his DNA apparently well distributed, he may have personally caused a substantial increase in civilization. In 2003, evolutionary geneticist Professor Chris Tyler-Smith of Oxford University analyzed the DNA of males across 16 Asian ethnic populations. Many shared the same Y-chromosome array. Dating the pattern back, Tyler-Smith found the origin appears to be Genghis Khan who ruled at the time the particular DNA array first emerged and then proliferated. Today, if you are a male reading this post, you may be part of 0.5% of the world’s population descending from Genghis Khan, who was born in 1162, died in 1227, and very busy in between.

Dynasties are continuations – traditions and genetics. Kublai Khan, Genghis’ nephew, inspired the mysterious poem by Samuel Taylor Coleridge. It begins:
In Xanadu did Kubla Khan
A stately pleasure-dome decree:
Where Alph, the sacred river, ran
Through caverns measureless to man
Down to a sunless sea…
But oh! that deep romantic chasm which slanted
Down the green hill athwart a cedarn cover!
A savage place! as holy and enchanted
As e’er beneath a waning moon was haunted
By woman wailing for her demon-lover!

While many animals (and a few plants) move around, humans may be the only species that builds roads, ships, and aircraft to do so. Human history can be traced by modes of transport: carts and wheels, ships and sails, trains and rails, tunnels and tubes, roads and vehicles, aircraft and wings, rockets and boosters. The ancient Silk Road, emanating from China around 206 bc, running 4,000 miles (6,437 kilometers), was one of the first extended paths over land. China’s Grand Canal connected to the sea via one of the world’s first inland waterways. Transport is about connection: ancient China achieved both land and sea routes that resulted in cultural and economic exchange.
In 2013, China announced the Belt and Road Initiative. Now, in 2023, here is a map of the project. “Topographic map of the Belt and Road Economic Corridor and pathway cities” by graphic artist, 18 October 2023. Creative commons 4.0. Included with appreciation.
One decade ago, China announced what some call Silk Road 2.0; its formal name is the Belt and Road Initiative (BRI). This week, representatives from nearly 150 countries met in Beijing to consider next steps. One agenda item: debt. China has reportedly financed airports, bridges, hydroelectric facilities, pipelines, ports, and roads in extensive world locations with an understanding that the receiving country would pay back loans and share user fees. There have been criticisms, as well as defaults and delays. Nepal’s new Pokhara Airport opened with a big price tag but as yet small revenue. China recently restructured debt with Argentina, Sri Lanka, and Zambia, among others. Not everyone is staying in the program; Italy had joined but is now trying to leave. But some countries and their leaders are decidedly there: Russia’s Putin was at the meeting, so was Haji Nooruddin Azizi, a minister of the Taliban. (Cash 2023)

Perhaps in response to concerns involving environmental and justice concerns, China launched the 2021 Global Development Initiative to promote “economic and social development” with a funding deposit of $10 billion. The total BRI extension in loans and grants is estimated at $1 trillion.
The Belt and Road Initiative has both pro and con issues. Image: “Plus, Minus, and Equality Signs” by graphic artist Sa-se. Creative Commons public domain. Included with appreciation.
While debt is a concerning issue (some say it is a con in the word’s two meanings) so is pollution: China’s overseas fossil-fuel power plants emit 245 million tons of CO2 annually. Another factor is land use change, with further environmental damage and loss of biodiversity, especially to land that is the home of original, indigenous people. However, there may also be pros. China has extended $500 billion in funding that some say could improve the infrastructure and industrial capabilities of some areas that desire growth but may have had challenges getting funding. From any angle, the Belt and Road Initiative is macro and global.
The Belt and Road Initiative may soon circle the world. It is one of the most important macro projects in history. Could the BRI be an opportunity for renewable energy, sustainable water, and perhaps even a new understanding of our interconnected world? How can you get involved to make it so?

The scope and span of the BRI make it one of the most significant agents in climate. The sheer volume of concrete, for example, could influence the environment: what if the BRI instituted a policy regarding the use of concrete as a carbon capture and containment? Ditto BRI’s energy use: as a leader in solar, could China favor renewable technology in BRI projects? BRi may be the biggest and most impactful construction project in history. We need to pay more attention. How can we influence climate and justice decisions? Want to know more? Start here, or here.

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.”

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.

Sahara, sea of sand, desert of legend, is ever-advancing. Over time, the Sahara Desert has expanded into the Sahel, a transnational ‘shore’ of African countries. Population in the Sahel has increased 120% in the last three decades: now, 64% of the population is under 25%. The encroaching Sahara, along with climate change induced heat and drought, is choking crops; 3.7 million people suffering the effects of crop loss, with shortages of millet and sorghum, staples. Famine, conflict, migration threaten the area. The Sahel reaches 3,360 miles from the Atlantic Ocean to the Indian Ocean, all across the southern belt of the Sahara Desert. What can be done? Two answers may be emerging.
The Sahara Desert, seen from space by satellite. The Sahel is just south of the desert. Image: wikimedia.
The Sahel has some of the largest aquifers in the continent, as much as 100 times annual rainfall and other renewable sources. But the Law of Transboundary Aquifers is still in draft. Sahel countries need to decide the use of shared water for drinking, agriculture, and industry. Agreements should also monitor extraction; some of the aquifers are sizable but slow to refill and replenish. Precedent for water sharing might include the Colorado River Compact, especially amendments. A future exploration of the Sahara itself may tap water resources under the sands, and a proposal by Frank P. Davidson for Lake Hope (2012).
Stopping Saharan desert expansion is important. The possibility of planting a green wall across the boundary of the Sahara to stem desert invasion of fertile lands adjacent is said to have been pondered by Richard St. Barbe Baker OBE during a study expedition to the Sahara in the mid 20th century. There was talk of building a test model of 30 miles at that time. But the present vision of green wall across Africa of 4,722 miles (7,600 kilometers) didn’t take root until 2002, when the Green Wall was re-introduced at the summit in Chad of the World Day to Combat Desertification and Drought. Support grew. Three years later, the concept was approved by the Community of Sahel-Saharan States; two years after that, in 2007, the African Union endorsed the “Great Green Wall for the Sahara and the Sahel Initiative.” The Great Green Wall hopes to restore and renew 100 million hectares by 2030, reduce CO2, absorbing 250 million tons, and create 10 million green jobs. Ethiopia has already restored 15 million hectares.

But results are still to be judged. Some point out that desertification is not just the fault of the Sahara, but instead may be due to deforestation and denuding of land. Observing success in applying traditional water conservation and harvesting methods, and nurturing of trees that appear naturally, the project is evolving into something that is working, in a different way. There are some who warn against some methods of afforestation, and choice of plantings is critical to success. Recent progress in Burkina Faso with building zaï, a grid planting method promoting water retention is one example. Another: increased respect for Faidherbia albida, an indigenous tree that defoliates during the rainy season, dropping leaves that fertilize soil, and also permit full sun during the subsequent early growing season. Other factors might be considered like walking paths, as envisioned by architect Benton MacKaye, resulting in the Appalachian Trail. Some suggest the Green Green Wall of Africa could become a model for a new CCC. The work of John D. Liu combines regreening with camps. Other green walls of afforestation include China’s Three-North Shelter Forest Program, China began the project in 1978 to stop the Gobi desert from advancing; while monoculture and some tree loss are problems, forest size has increased from 5% to 13.% with 13 million hectares (32 million acres) of trees planted (an area the size of western Europe). China will complete the afforestation project in 2050. India’s Green Wall of Aravalli, proposed by Vijaypal Baghel at COP 14 would build 1,6000 km of green; and Great Hedge of India, originally related to customs control line for 1870’s salt tax, and later grown into a living hedge. Progress of green walls can now be tracked through Earth Observation Satellites. ESA’s Prova-V monitors the Sahel.

Macroengineering endeavors involving transboundary resources may require an organizational form that allows for coordination of many different and interacting systems. As climate change affects regions, not just nations, will we see more macro solutions? The advancing Sahara desert does not stop at the Mali border but threatens the whole southern edge of the desert. The rising Atlantic ocean does not stop at Maine in the United States but continues to lap the coast of Canada. Africa’s Great Green Wall may set an example.
When completed, the Great Green Wall of the Sahel would be the largest living structure on Earth – three times the size of the Great Barrier Reef. The 7,600 km (4,000 plus miles) natural wonder of the world may be visible from space. As the Great Green Wall evolves to benefit from traditional water conservation measures, countries of the Sahel may work together to rebuild and strengthen the fertility of the land and its treasured water resources, the Sahel may build more than a wall, but also a foundation.

Bird watchers in Hong Kong? Nature lovers in Shenzhen? In between these two megacities with a combined population of 20 million, rare birds fly and feed in one of the world’s most precious wetlands. Egrets, herons, sandpipers abound on the mudflats. Will the wetlands, about 4,000 acres, continue to be the green jewel of Hong Kong? Mai Po Nature Reserve is protected by the Ramsar Convention. But Nam Sang Wai, about 400 acre parcel, recently debated a proposal for 10% of the area to build apartments for 6,500 people. Henderson Land Development pledged to model the project on the London Wetland Centre where financing included provisions to preserve the natural habitat. Another precedent? The New River, bringing fresh water to London while preserving a natural walking path, albeit not residential but just recreational. Meanwhile, if you visit Hong Kong or Shenzhen, consider the sampan ride across the Shan Pui River; it’s the only human-powered ferry in Hong Kong.

Hong Kong-Zhuhai-Macau Bridge, China. Take a test drive. Image: wikimedia.
World’s longest span, China’s Hong Kong-Zhuhai-Macau Bridge, stretches 34 miles (55 km) across the Pearl River Delta. An artificial island supporting Zhuhai’s port joins the financial centers of Hong Kong, Shenzhen (Special Economic Zone), and manufacturing areas like Dongguan. The bridge cuts travel time between Zhuhai and Hong Kong, formerly taking 4 hours, to 40 minutes. One unique aspect revealing cultural history: traffic patterns change from left-lane driving (in once-British Hong Kong) to right-lane vehicular traffic (the rule of the road in China).
Brooklyn Bridge. Image: wikimedia commons.
Bridges have long encouraged economic activity. London Bridge was perhaps the first shopping mall: spaces along the span were leased to stores whose taxes paid for bridge maintenance. The Brooklyn Bridge cost $15 million to build. Tolls varied: it cost one penny to walk across but double that if you brought a horse or cow, and ten times more with a one-horse wagon. Fifteen years after the bridge joined Manhattan and Brooklyn, the latter’s population doubled and both economies grew rapidly.
China’s new bridge may promise economic development but also drew headlines for costs: $7 billion for the 14 mile main span; $13 billion for tunnels. The project used enough steel (400,000 tons) to build 60 Eiffel Towers. There were also costs in lives lost: 10 people perished during construction; another 500 were injured. There were costly delays (the project was two years late) and troubling scandals: 19 people were indicted on criminal charges for fake concrete. Another cost: the number of rare white dolphins (sometimes called China’s marine panda) swimming in Hong Kong waters dropped by half, even though $68 million was devoted to their protection.

How can the Hong Kong-Zhuhai-Macau Bridge assure environmental stability? Will the University Alliance of the Silk Road and the Confucius Institute help to bring sustainable and inclusive values that are perhaps the most important bridges?

Building a better world – with carrots. That crunchy veggie could be used to strengthen concrete, improving construction techniques, and the environment. Blending carrots into building products makes those materials as much as 80% stronger, according to Mohamed Saafi, Professor and Chair in Structural Integrity and Materials at Lancaster University. Not only stronger, carrot-fortified concrete also develops fewer cracks – the carrots seem to act like superglue – so less cement is required, resulting in a lower carbon output. Could it make a difference in our world? Yes. Cement is the source of 7% of global carbon dioxide emissions.
Roman Bridge at Cangas. Image: wikimedia commons.
Ancient Rome built superior roads and bridges by using materials strengthened by a mix-in of volcanic ash. The Great Wall of China was initially built by compacting reeds and mud, a combination that proved stronger and easily scalable, since the materials were available onsite, important when building a 13,000 mile wall. Bridges on the Grand Canal are another example. Mix-ins have long strengthened building materials.
Meanwhile, the next time you munch on a carrot, consider what Christian Kemp-Griffin, CEO of CelluComp, explained: “Those fibers have strength characteristics in them. It’s the building blocks of the strength of a vegetable.” Because carrots contain so much water, only a very small amount of cellulose of a carrot will alter the property of cement, because water changes as cement hardens. Kemp-Griffin continued: “It’s not the physical fiber that’s causing the strength. It’s the way it holds water. There’s a chemical reaction happening between the fibers and the cement.”

Finally, it’s free, or almost free. CelluComp uses industrial leftovers: carrot peels from those machines that give you pre-cut carrots. Beets are next; there’s a lot of beet pulp after sugar production; 20% of the world’s sugar is made from beets. Brazil leads in sugar production (mainly cane sugar, the other 80%); but building markets may take note of Russia, France, USA, Germany, and Turkey, largest producers of sugar beets. Or, building big with carrots may happen in New Zealand, home to Ohakune, and the big carrot pictured above.

Next time you hail a ride, consider this: China’s ride-hailing market is already greater than the entire world’s combined, at $30 billion. The United States ride-hailing market is $12 billion. A report by Bain & Company predicts China’s market will soon double. China’s equivalent of Uber and Lyft is Didi Chuxing. In fact, Didi bought out Uber’s China operations in 2016, giving the company instead a 18% stake in Didi. But only 40% of ride requests arrive via the Didi app; equally powerful are Tencent’s WeChat and Alibaba’s Allpay. Order movie tickets and dinner along with your ride? Do it in one click with Meituan Dianping, with 320 million users. Bain’s Raymond Tsang estimates China’s ride-hailing market will reach $72 billion by 2020. The advent of self-driving vehicles may be part of the strategy: Didi is an AI and autonomous conglomerate. When the United States Transcontinental Railroad was built, telegraph communications infrastructure was laid under the tracks. Will ride-hailing vehicle and communications infrastructure be planned as part of the Belt and Road Initiative, bringing the New Silk Road into the future?
For telegraph infrastructure combined with transport building, see sections 18 and 19 of “An Act to aid in the Construction of a Railroad and Telegraph Line,” 1 July, 1862. Building the World, pages 237-238.

We emerged from the forest; will forest cities return us to our natural state? Image: Shennongjia Forest, Hubei, China. Image: wikimedia commons.
China’s plans for a “Forest City” may establish a vision for a better urban future. New cities have often marked turning points in history. In the year 145 (or A.D. 762), the new Caliph of the Abbasid dynasty decided to move the capital to create a fresh vision. Setting off on horseback, Al-Mansur saw an auspicious spot, leapt from his steed, drew his sword, and carved three concentric circles upon the land. The new city? The Caliph named it Medinat as-Salam, “City of Peace.” Today, it is called Baghdad.
Liuzhou Forest City will not only be attractively leafy, it will literally eat smog. Commissioned by Liuzhou Municipality Urban Planning, Stefano Boeri Architetti designed the green vision:
Hosting 40,000 trees;
Growing 1 million plants of 100 species;
Absorbing 10,000 tons of CO2;
Eating 57 tons of fine dust and pollutants;
Producing 900 tons of fresh Oxygen.
Liuzhou, famous place on the Silk Road, builds upon the vision of Vertical Forests, as seen in Milan, Italy, or the Meir Lobaton & Kristjan Donaldson Torre Cuajimalpa in Mexico. Comparisons might also be made to Rhode Island’s tree-planting project designed by the School of Architecture, Art, and Historic Preservation of Roger Williams University.
No room to plant trees? Answer: CityTree, a green “wall” of plants with as much air-purifying power as 275 trees. Co-founder Zhengliang Wu of Green City Solutions recommends moss cultures because of their larger leaf surface areas.

Cities around the world are seeking resilient responses to climate change. Energy, water, and transport systems are among the areas experiencing innovation. Sea level rise threatens many coastal cities including San Francisco and Silicon Valley, studied by system dynamics experts Christiansen and Libby. And it is not a moment too soon: by 2050, 75% of all the people in the world will live in cities. Will Liuzhou Forest City mark a point in history turning toward sustainability?

“Sunrise on the Grand Canal of China.” William Havell, 1817. Image: wikimedia commons.
Infrastructure has been termed the foundation of civilization. Rome built roads, and water systems; the aqueducts made possible the expansion of the city and the empire. China built the Grand Canal, stimulating commerce, culture, and communication: the written language was first standardized because of the Canal. Throughout history, infrastructure has spurred civilization. The world currently spends $2.5 trillion on water, energy, transport, and telecommunications – each year. But, according to the McKinsey Global Institute, $3.3 trillion is needed just to keep up. What’s more worrying? Emerging and developing areas will require more of everything: electricity, roads, rail, airports, shipping ports. Aggregate investment from now until 2030 will be significant: 49 trillion. Initiatives like China’s New Silk Road (One Belt, One Road) may globalize infrastructure that is environmentally sustainable and beneficial. Bringing new infrastructure to areas in need is a chance, perhaps unprecedented in history, to rebuild the world.
