Visualization of place in everyday life

visual carpet Seyed Alavi, a Californian artist, created a wonderful visualization in a public art/carpet for a bridge at Sacremento airport. He writes:

This project consists of an aerial view of the Sacramento River that is woven into a carpet for the floor of a pedestrian bridge connecting the terminal to the parking garage. This image represents approximately 50 miles of the Sacramento River starting just outside of Colusa, California and ending about 6 miles south of Chico.

In addition to recalling the experience of flight and flying, this piece, by depicting the larger geographical area, also helps to reinforce a sense of belonging and/or connection for the traveler. In this way, the carpet can also be read and experienced as a “welcome mat” for visitors arriving in Sacramento.

Future of Scientific Methods

The website Edge, has Kevin Kelly’s Speculations on the future of science based on a talk he gave to the Long Now Foundation. Stewart Brand, of the Foundation, introduces Kelly’s article:

Recursion is the essence of science. For example, science papers cite other science papers, and that process of research pointing at itself invokes a whole higher level, the emergent shape of citation space. Recursion always does that. It is the engine of scientific progress and thus of the progress of society.

A particularly fruitful way to look at the history of science is to study how science itself has changed over time, with an eye to what that trajectory might suggest about the future. Kelly chronicled a sequence of new recursive devices in science.

Africa ReOrienting?

The world economy is ReOrientating towards Asia. The Jan 2006 issue of the British literary magazine Granta is focussed on Africa. In an article We Love China the British journalist Lindsey Hilsum writes about what Chinese investment may mean to Africa (and China).

I arrived in Sierra Leone in June 2005, at the height of the rainy season. Mud washed down the pot-holed streets of the capital, Freetown, and knots of beggars, some without arms or legs, huddled under trees and against battered shop-fronts. It was a fortnight before the G8 summit in Gleneagles, Scotland, where Bob Geldof and Bono were to celebrate a huge increase in aid to Africa, but in the Bintumani Hotel no-one spoke of this. Gusts of rain-filled wind blew through the hotel’s porch to set the large red lanterns swinging. Cardboard cut-outs of Chinese children in traditional dress had been stuck on the windows. The management had just celebrated Chinese New Year

Most European companies abandoned Sierra Leone long ago, but where Africa’s traditional business partners see only difficulty, the Chinese see opportunity. They are the new pioneers in Africa, and—seemingly unnoticed by aid planners and foreign ministries in Europe—they are changing the face of the continent. Forty years ago, Chinese interests in Africa were ideological. They built the TanZam railway as a way of linking Tanzania to Zambia while bypassing apartheid South Africa. Black and white footage shows Chinese workers in wide-brimmed straw hats laying sleepers, and a youthful President Kenneth Kaunda of Zambia waving his white handkerchief as he mounted the first train. As an emblem of solidarity, China built stadiums for football matches and political rallies in most African countries which declared themselves socialist. In the 1980s and 1990s, the Middle Kingdom withdrew to concentrate on its own development, but in 2000 the first China–Africa Forum, held in Beijing, signalled renewed interest in Africa. Now, the Chinese are the most voracious capitalists on the continent and trade between China and Africa is doubling every year.

Megacities: 3 views

In the next fifty years the world’s population is expected to increase by roughly 50%. Almost of of this population growth is expected to be in cities in the developing world. Mike Davis’ Planet of Slums presents one vision of the developing world’s megacities. Below are three others.

Shadow cities cover Robert Neuwrith’s informative and novel book Shadow Cities: A Billion Squatters, A New Urban World (see review on WorldChanging) is about the one billion people who live in informal settlements in the world’s megacities. Neuwrith lived in informal settlements in Bombay (Mumbai), Rio de Janeiro, Istanbul, and Nairobi. Based on his experience he argues that rather than being zones of chaos and crime, shantytowns are innovative and adaptive responses to poverty that allow poor people to improve their lives - as long as their governments don’t evict and destroy their settlements. Neuwirth also maintains a weblog that comments on new related to his book.

Cover Maximum City Suketu Mehta’s great book Maximum City: Bombay Lost and Found presents a rich evocative picture of Bombay (Adam Hochschild review in Harpers). Mehta tells the stories of gansters, policemen, politicians, dancers, Bollywood stars, the middle class, the poor, and the rich. He tells of the failure of state justice, police assassinations of gangsters, and the intertwined stories of gangsters and movie stars - as well as Bombay’s connection with Dubai, India and the West.

Finally, a Guardian article tells the story of a day in Chongqing - the fastest-growing urban centre on the planet - just upstream from the reservoir of the Three Gorges Dam (see Edward Burtynsky photos).

China’s development is one of humanity’s worst environmental disasters. Cheap coal and a doubling of car ownership every five years has made the country the second-biggest emitter of greenhouse gases. According to the World Bank, 16 of the planet’s 20 dirtiest cities are in China, and Chongqing is one of the worst. Every year, the choking atmosphere is responsible for thousands of premature deaths and tens of thousands of cases of chronic bronchitis. Last year, the air quality failed to reach level 2, the government health standard, one day in every four. Today’s haze is so thick that I still haven’t seen the sun.

Outside at midnight, the bright lights cannot mask a seedier side of city life - the poor trawling through rubbish bins, the homeless on street corners, the touts offering drugs and sex for sale. Many of the women working as prostitutes are rural migrants. Their children are left with relatives or sent to the streets to beg, sell flowers or sing songs for money until the early hours.

Ruin and Recovery

Ruin & Recovery is a special series of newspaper articles in the New Orleans Times-Picayune on how other cities responded to disasters:

  • Galveston, TX - Galveston almost went under in the hurricane of 1900, but city leaders saved it, and a new economy reshaped it.
  • Charleston, SC - Historic Charleston survived Hurricane Hugo and rebuilt, keeping its charm
  • Grand Forks, ND - Lessons learned after devastating floods in 1997
  • Homestead, FL - Hurricane Andrew nearly wiped Homestead off the map. But after early stumbles, and a lot of help from private enterprise, the town is stronger than ever
  • Kobe, Japan - In seconds, buildings collapsed, bridges toppled and thousands died when an earthquake hit Kobe, Japan, 10 years ago. Despair was rampant. But with dogged determination, the city rebuilt, repopulated and rebounded
  • The Netherlands - After a North Sea flood killed nearly 2,000 peole in the Netherlands in 1953, building a state-of-the-art flood defense became a national priority.

Planet of Slums

World Press PhotosThe prolific and controversial urban critic, Mike Davis, has a new book Planet of Slums. It is based upon his article Planet of Slums in New Left Review (March-April 2004). In Planet of Slums he writes:

There may be more than quarter of a million slums on earth. The five great metropolises of South Asia (Karachi, Mumbai, Delhi, Kolkata and Dhaka) alone contain about 15,000 distinct slum communities with a total population of more than 20 million. An even larger slum population crowds the urbanizing littoral of West Africa, while other huge conurbations of poverty sprawl across Anatolia and the Ethiopian highlands; hug the base of the Andes and the Himalayas; explode outward from the skyscraper cores of Mexico, Jo-burg, Manila and São Paulo; and, of course, line the banks of the rivers Amazon, Niger, Congo, Nile, Tigris, Ganges, Irrawaddy and Mekong. The building blocks of this slum planet, paradoxically, are both utterly interchangeable and spontaneously unique: including the bustees of Kolkata, the chawls and zopadpattis of Mumbai, the katchi abadis of Karachi, the kampungs of Jakarta, the iskwaters of Manila, the shammasas of Khartoum, the umjondolos of Durban, the intra-murios of Rabat, the bidonvilles of Abidjan, the baladis of Cairo, the gecekondus of Ankara, the conventillos of Quito, the favelas of Brazil, the villas miseria of Buenos Aires and the colonias populares of Mexico City. They are the gritty antipodes to the generic fantasy-scapes and residential themeparks—Philip K. Dick’s bourgeois ‘Offworlds’—in which the global middle classes increasingly prefer to cloister themselves.

Teddy Cruz - What adaptive architecture can learn from Shantytowns

From Mixed Feelings Teddy Cruz a California architecture, who has focussed on what architecture can be learnt from informal settlements is profiled in an article Border-town muse: An architect finds a model in Tijuana from the March 13 International Herald Tribune.

The IHT article writes:

As Tijuana has expanded into the hilly terrain to the east, squatters have fashioned an elaborate system of retaining walls out of used tires packed with earth. The houses jostling on the incline are constructed out of concrete blocks, sheets of corrugated metal, used garage doors and discarded packing crates - much of it brought down by local contractors and wholesalers from across the border (slideshow in NY Times).

Once such a settlement is completed, it is protected from demolition under Mexican law - and the government is eventually obliged to provide plumbing, electricity and roads to serve it. In Cruz’s view, the process is in some ways a far more flexible and democratic form of urban development than is the norm elsewhere.

Fortune Article on Ecological Resilience: Cloudy With a Chance of Chaos

Eugene Linden a journalist, who has recently published a book on climate change - The Winds of Change: Climate, Weather, and the Destruction of Civilizations, in Jan 2006 wrote an article Cloudy With a Chance of Chaos in the US business magazine Fortune. In it he discusses how ecological degredation has lead to a decline of ecological resilience.

Around the world, humanity has reduced nature’s capacity to dampen extremes to an astonishing degree: more than 59% of the world’s accessible land degraded by improper agriculture, deforestation, and development; half the world’s available fresh water now co-opted for human use at the expense of other species and ecosystems; more than half the world’s mangroves destroyed; half the world’s wetlands drained or ruined; one-fifth of the world’s coral reefs (including crucial barrier reefs) destroyed and one-half damaged–the list goes on and on.Nature does not alert us to all her tripwires. Perhaps that’s why in recent years the unprecedented has become increasingly ordinary. When pushed past a certain magnitude, the damage of natural events increases exponentially, and that threshold falls as natural buffers are eliminated. Research led by MIT climatologist Kerry Emmanuel suggests that hurricanes have doubled in intensity during the past 30 years as the oceans have warmed. Hurricane Katrina surged to its immense power when the storm passed over a deep layer of 90-degree Fahrenheit water in the Gulf of Mexico. Hurricane Rita transfixed meteorologists when it strengthened from Category 2 to 5 in less than 24 hours while moving over those same hot seas. And in October, Wilma bested that by strengthening from tropical storm to Category 5 hurricane in a single day.

Recovery Happens - Asian Tsunami impacts after one year

Jamais Cascio posts on WorldChanging

photo 8 thailand then and nowIn the immediate aftermath of the December 26, 2004, tsunami, we pointed to satellite photos showing the before-and-after of coastal regions of Thailand, Sri Lanka, Indonesia, India and other affected locations. These images were among the most powerful representations of the disaster, as viewers could easily trace the path of destruction. New before-and-after images are now available, but these tell a very different story.

Photojournalist Zoriah covered both Sri Lanka and Thailand in the days following the tsunami; earlier this year, Zoriah returned to Thailand, and took pictures at the exact same sets of locations. WarShooter.com, a web portal for photojournalists covering conflict and disaster, posted the resulting side-by-side comparison this weekend. Some of the changes are subtle, but it’s clear that much of Thailand is well on the road to recovery.

John Stanmeyer also posted before-and-after shots, this time of Banda Aceh, Indonesia. Aceh still has much further to go than Thailand, but these images stand as record that human beings can, and will, choose to survive and flourish even in the wake of unthinkable disaster. (Warning: the first image of Stanmeyer’s collection includes a fully-visible corpse; the subsequent images aren’t nearly as disturbing.)

Watermark: can southern Louisiana be saved

New Orleans Flooded after KatrinaElizabeth Kolbert, a writer for the New Yorker, who also wrote a series of articles - Climate of Man - about climate change. Wrote a fairly grim article Watermark: can southern Louisiana be saved, in the Feb 27, 2006 New Yorker. She writes about geology, wetland loss, climate change, and people of New Orleans.

Five thousand years ago, much of southern Louisiana did not exist. A hundred years from now, it is unclear how much of it will remain. The region, it is often observed, is losing land at the rate of a football field every thirty-eight minutes. Alternatively, it is said, the area is shrinking by a large desktop’s worth of ground every second, or a tennis court’s worth every thirteen seconds, or twenty-five square miles a year. Between 1930 and 2000, some 1.2 million acres, an area roughly the size of Delaware, disappeared. Hurricanes Katrina and Rita stripped away an estimated seventy-five thousand acres—a loss as big as Manhattan and Brooklyn combined. The U.S. Geological Survey has published a map illustrating the process. Areas that have already vanished appear in red, and areas that are expected to vanish by 2050 in yellow. On the map, the southern coast looks as if it were on fire. According to the U.S. Army Corps of Engineers, “The rate at which Louisiana’s land is converting to water is probably the fastest in the world. [here is an animated map]
