How Africa is Becoming the New Asia

Pretoria, South Africa
from Newsweek.com
By Jerry Guo

China and India get all the headlines for their economic prowess, but there's another global growth story that is easily overlooked: Africa. In 2007 and 2008, southern Africa, the Great Lakes region of Kenya, Tanzania, and Uganda, and even the drought-stricken Horn of Africa had GDP growth rates on par with Asia's two powerhouses. Last year, in the depths of global recession, the continent clocked almost 2 percent growth, roughly equal to the rates in the Middle East, and outperforming everywhere else but India and China. This year and in 2011, Africa will grow by 4.8 percent—the highest rate of growth outside Asia, and higher than even the oft-buzzed-about economies of Brazil, Russia, Mexico, and Eastern Europe, according to newly revised IMF estimates. In fact, on a per capita basis, Africans are already richer than Indians, and a dozen African states have higher gross national income per capita than China.

More surprising is that much of this growth is driven not by the sale of raw materials, like oil or diamonds, but by a burgeoning domestic market, the largest outside India and China. In the last four years, the surge in private consumption of goods and services has accounted for two thirds of Africa's GDP growth. The rapidly emerging African middle class could number as many as 300 million, out of a total population of 1 billion, according to development expert Vijay Majahan, author of the 2009 book Africa Rising. While few of them have the kind of disposable income found in Asia and the West, these accountants, teachers, maids, taxi drivers, even roadside street vendors, are driving up demand for goods and services like cell phones, bank accounts, upmarket foodstuffs, and real estate. In fact, in Africa's 10 largest economies, the service sector makes up 40 percent of GDP, not too far from India's 53 percent. "The new Africa story is consumption," says Graham Thomas, head of principal investment at Standard Bank Group, which operates in 17 African countries.

Much of the boom in this new consumer class can be attributed to outside forces: evolving trade patterns, particularly from increased demand coming out of China, and technological innovation abroad that spurs local productivity and growth like the multibillion-dollar fiber-optic lines that are being laid out between Africa and the developed world. Other changes are domestic and deliberate. Despite Africa's well-founded reputation for corruption and poor governance, a substantial chunk of the continent has quietly experienced this economic renaissance by dint of its virtually unprecedented political stability. Spurred by eager investors, governments have steadily deregulated industries and developed infrastructure. As a result, countries such as Kenya and Botswana now boast privately owned world-class hospitals, charter schools, and toll roads that are actually safe to drive on. A study by a World Bank program, the Africa Infrastructure Country Diagnostic, found that improvements in Africa's telecom infrastructure have contributed as much as 1 percent to per capita GDP growth, a bigger role than changes in monetary or fiscal policies. Shares of stocks in recently privatized local airlines, freight companies, and telecoms have skyrocketed.

Entrepreneurship has increased at the same time, powered in part by the influx of returning skilled workers. Just as waves of expats returned to China and India in the 1990s to start businesses that in turn attracted more outside talent and capital, there are now signs that an entrepreneurial African diaspora will help transform the continent. While brain drain is still a chronic problem in countries such as Burundi and Malawi—some of the poorest in the world on a per capita basis—Africa's most robust economies, such as those in Ghana, Botswana, and South Africa, are beginning to see an unprecedented brain gain. According to some reports, roughly 10,000 skilled professionals have returned to Nigeria in the last year, and the number of educated Angolans seeking jobs back home has spiked 10-fold, to 1,000, in the last five years. Bart Nnaji gave up a tenured professorship at the University of Pittsburgh to move back to Nigeria in 2005 and run Geometric Power, the first private power company in sub-Saharan Africa. Its $400 million, 188-megawatt power plant will come online this fall as the sole provider of electricity for Aba, a city of 2 million in southeast Nigeria. Afam Onyema, a 30-year-old graduate of Harvard and Stanford Law, turned down six-figure offers in corporate law to build and run a $50 million state-of-the-art private hospital with a charitable component for the poor in southeast Nigeria.

Many experts believe Africa, with its expansive base of newly minted consumers, may very well be on the verge of becoming the next India, thanks to frenetic urbanization and the sort of big push in services and infrastructure that transformed the Asian subcontinent 15 years ago. Just as India once harnessed its booming population of cheap labor, Africa stands to gain by the rapid growth of its big cities. Already the continent boasts the world's highest rate of urbanization, which jump-starts growth through industrialization and economies of scale. Today only a third of Africa's population lives in cities, but that segment accounts for 80 percent of total GDP, according to the U.N. Centre for Human Settlements. In the next 30 years, half the continent's population will be living in cities.

Nowhere is this relationship between the consumer class and urbanization more apparent than in Lagos, Nigeria, a megalopolis of 18 million that has the anything-goes pace of a Chongqing or Mumbai. On Victoria Island, the city's commercial center, real estate is as expensive as in Manhattan. Everywhere you look, there is construction: luxury condos, office buildings, roads, even a brand-new city nearby being dredged from the sea that will hold half a million people. "Everything is in short supply, so everything's a high-growth area," explains Adedotun Sulaiman, a venture capitalist and chairman of Accenture in Nigeria. "In terms of opportunities, it's just mind-blowing." Aliko Dangote, Africa's richest black entrepreneur, has also cashed in on this consumer culture, with a net worth of $2.5 billion, according to Forbes. His empire, which began in 1978 as a trading business that imported, among other things, baby food, cement, and frozen fish, is focused on Nigeria's burgeoning domestic growth, producing cement for shopping and office complexes; renting luxury condos; making noodles, flour, and sugar; and now expanding into services such as 3G mobile networks and transportation. "There's nowhere you can make money like in Nigeria," says the 53-year-old Dangote. "It's the world's best-kept secret."

Not anymore. A recent study by Oxford economist Paul Collier of all 954 publicly traded African companies operating between 2000 and 2007 found that their annual return on capital was on average 65 percent higher than those of similar firms in China, India, Vietnam, or Indonesia because labor costs are skyrocketing in Asia. Their median profit margin, 11 percent, was also higher than in Asia or South America. African mobile operators, for instance, showed the highest profit margins in the industry worldwide. As a result, foreign multinationals like Unilever, Nestlé, and Swissport International report some of their highest growth in Africa. So even as foreign direct investment fell by 20 percent worldwide in 2008, capital in-flows to Africa actually jumped 16 percent, to $61.9 billion, its highest level ever, according to a report by the Organization for Economic Cooperation and Development. Even Chinese companies are thinking of outsourcing basic manufacturing to Africa. The World Bank is now helping China set up an industrial zone in Ethiopia, the first of perhaps several offshore centers akin to the sprawling free-trade zones that opened up China's economy in the 1980s.

Still, Africa remains at the very frontier of emerging markets. Despite its gains, the difficulty and cost of running a business there are the highest in the world, according to data from the International Monetary Fund. Couple that with pervasive corruption—Transparency International calls the problem "rampant" in 36 of 53 African states—and it's no wonder Africa is often regarded as a toxic place to operate. But World Bank president Robert Zoellick says that in the aftermath of the economic crisis, long-term investors have recognized that "developed markets have big risks too." Like China and India, Africa is exploiting that fact, and perhaps more than any other region it is illustrative of a new world order in which the poorest nations will still find ways to steam ahead.

"...while small forest fragments need protecting we should intervene at an earlier stage to protect larger forest areas that are under threat"

Threat to Monkey Numbers from Forest Decline
From ScienceDaily.com
Monkey populations in threatened forests are far more sensitive to damage to their habitat than previously thought, according to new research.

An analysis of monkeys living in Tanzania's Udzungwa Mountains suggests that the impact of external factors, such as human activity, on species numbers is felt in forests as large as 40 square kilometres.

Researchers also found that the health of monkey populations is closely related to the type of habitat found between forest fragments, rather than the distance that separates them.

The findings have broader implications for conservationists as the number of monkeys and the variety of species is a visible indicator of the underlying health of their habitat.

The research was conducted by Dr Andrew Marshall, from the Environment Department at the University of York and Director of Conservation at Flamingo Land Theme Park and Zoo, in collaboration with colleagues from the University of York, the University of Copenhagen, the Tremto Museum of Natural History (Italy) and the Udzungwa Ecological Monitoring Centre (Tanzania).

Dr Marshall said: "This study suggests that while small forest fragments need protecting we should intervene at an earlier stage to protect larger forest areas that are under threat.

"It also supports the case for working with local communities on practical steps that will help forest species. These could include reducing dependence on bush meat and encouraging the planting of habitat that can form corridors between forest fragments."

The research investigated the distribution of seven species living in an area covering 10,000 km2 and has led to a wider conservation and education project in the area led by Dr Marshall, through Flamingo Land Theme Park and Zoo. The discovery of a new species of chameleon in this area was announced last year.

The latest research is published in the American Journal of Primatology.

Canadians win the NSF 2009 International Science & Engineering Visualization Challenge

From Sciencemag.org
2009 Visualization Challenge: Interactive Media
Science and the National Science Foundation announce the winner in the interactive media category in the 2009 International Science & Engineering Visualization Challenge.

First-Place Winner - Genomics Digital Lab: Cell Biology

Video games allow players to rock out like Jimi Hendrix or hurl touchdown passes like Peyton Manning. In this interactive media entry, they can turn sunlight into electrons and convert sugar into energy like a plant cell. Jeremy Friedberg and his team at Spongelab Interactive in Toronto, Canada, designed this Web-based game to teach high school students about the intricate cycles and pathways that keep the cell alive by generating and burning energy.

At the start of each game, the camera zooms into the cross section of a leaf and focuses on a glowing cell. Then the students must play the role of that cell, building and maintaining its cycles and pathways to score energy points. In one game, players have to manage glycolysis, the pathway that breaks down the sugar glucose, by shooting enzymes at molecules marching on tracks to convert them into new chemicals that the cell can use. The final games focus on transcribing genes and synthesizing proteins—processes on which cells spend much of their energy. Similar to Guitar Hero, players transcribing a gene must hit the appropriate RNA base letter as the DNA template scrolls down the screen. Too many mistakes and the cell becomes sick.

Games can be important educational tools that go beyond rote memorization, Freidberg says. "I want to know if my students can think critically and be creative and figure out ways through problems," he says. "That's what games can do: They can create scenarios that make students problem-solve."

The judges "were impressed with the incredible attention to detail and accurate representation of cell structures ... as well as the use of story lines to draw in and sustain the users' attention," says panel of judges member Tierney Thys. "My only wish is that I'd had more time to play it!"

Sign the Petition to ban the sale and trade in Ivory

From bloodyivory.org

In 1979 there were an estimated 1.3 million African elephants. A decade later, widespread poaching had reduced that figure by half. Just 600,000 African elephants remained.

Africa’s savannahs and forests were no longer sanctuaries for elephants; they had been turned into graveyards.

In 1989, a worldwide ban on ivory trade was approved by CITES. Levels of poaching fell dramatically, and black-market prices of ivory slumped.

CITES had saved the African elephant. Or had it?

Since 1997, there have been sustained attempts by certain countries to overturn the ban. In 1999, South Africa, Botswana, Namibia and Zimbabwe were allowed an ‘experimental one-off sale’ of 49,437kg of ivory to Japan. Then in 2002, a further one off-sale was approved, which finally took place in 2008 – and resulted in 105,000kg of ivory being shipped to China and Japan.

Today, levels of poaching and illegal trade are spiralling out of control once again. In many areas, rates of poaching are now the worst they have been since 1989. In 2009, over 20,000kg of ivory was seized and countries have started to report localised extinctions of very vulnerable elephant populations.

Despite this, in March 2010, Tanzania and Zambia will be asking to reduce the level of protection their elephants afforded by CITES (by downlisting their elephant populations from Appendix I, which bans commercial trade, to Appendix II, which allows regulated trade subject to certain conditions). They are also seeking approval for a one-off sale of over 110,000kg of ivory.

The Tanzania and Zambia Proposals are in direct contravention of the spirit a nine-year moratorium on ivory trade, agreed by all range States in 2007. The final wording of this moratorium unfortunately has a loophole which is now being exploited by Tanzania and Zambia.

If these proposals are approved, many fear for the future survival of many of Africa’s more fragile elephant populations that simply cannot withstand any more pressure. For Sierra Leone’s elephants it is already too late – the Government of Sierra Leone announced at the end of 2009 that it feared its last few elephants had been lost to poachers.

The African Elephant Coalition is formed of 23-African elephant range States (the majority of countries with wild African elephants) who are strongly opposing the Tanzanian and Zambian Proposals. They are instead calling on the international community to support a proposal by Ghana, Republic of Congo, Rwanda, Mali, Kenya, Liberia and Sierra Leone to close the loophole in the moratorium, and extend it to twenty years. They believe that only resolute action of this kind can increase the security for Africa’s beleaguered elephants.

This website is intended to be a central portal of information about ivory trade, elephant poaching and the impact of CITES decisions on Africa’s elephants.

It provides those without a voice to join in the battle to protect elephants across Africa. They urgently need your support. Don’t delay – take action today!

US Congress Considers Banning Medical Experiments on Chimpanzees

To quote from this article:
says Vandeberg. "It would be unethical for us to turn our back on these people and not conduct the research that is so desperately needed to develop the drugs to treat these diseases and the vaccines to prevent them in the future."
And what if the only way to not turn our backs on these people was to test on people? Does Dr. Vandeberg support human testing, or does he draw lines? And if he draws lines, what are his criteria? cognition? adult apes are "smarter" than small children and "smarter" that some mentally challenged will ever be. Is it at those that possess an emotional life? We know apes care for kin and others as we do. And if its some "species" designation, lets not forget that less than 100 years ago "blacks" and "whites" were considered different species. If you have ever watched apes, then you know that biomedical tests on them is as wrong as tests on humans. -MA

Congress Considers Banning Medical Experiments on Chimpanzees
Scientists, animal rights advocates, spar over lab tests on chimps
by Julie Taboh

The United States is the only country in the world that still allows federally-funded medical experiments on chimpanzees.

Chimpanzees are our closest animal relative. So close, in fact, that 98 percent of a chimpanzee's DNA is identical to that of humans.

The highly intelligent primates share many of our physical and behavioral characteristics and that similarity has made them attractive to medical researchers, sparking a heated debate over animal rights and medical ethics.

Essential or inhumane

The United States is the only country in the world that still allows federally-funded medical experiments on chimpanzees. The practice includes developing and testing new vaccines and drugs that might prevent or cure potentially-fatal human diseases.

Supporters of the practice say medical tests involving chimps have helped save millions of lives worldwide. Animal welfare activists argue that subjecting chimpanzees to painful, and often lethal, experiments is cruel and inhumane.

Dr. Hope Ferdowsian, director of research policy at the nonprofit Physicians Committee for Responsible Medicine (PCRM), says chimpanzees used for HIV and hepatitis research are anaesthetized with a dart gun before being subjected to harmful and invasive procedures. Besides its ethical objections, PCRM argues that the use of chimpanzees in the lab is an ineffective way to advance medical research.

"Over 80 different vaccines have worked in chimpanzees with respect to HIV virus; none of them have worked in human beings," says Elizabeth Kucinich, wife of U.S. Congressman Dennis Kucinich, director of public affairs, Physicians Committee for Responsible Medicine.

Ineffective in humans?
Elizabeth Kucinich, wife of U.S. Congressman Dennis Kucinich, is a long-time animal welfare advocate. She also serves as director of public affairs for the Physicians Committee.

Kucinich says science has evolved since the 1920s when primates were first used for experimentation. "Since that time we've really learned that as close as they are to human species, they're not close enough for any real scientific outcomes for drug testing."

According to Kucinich, over 80 different HIV-related vaccines have worked in chimpanzees but none have proven effective in human beings.

A recent undercover investigation conducted by the Humane Society of the United States found chimpanzees in a Louisiana research center being subjected to harsh treatment and painful medical experiments.

They also found these highly social animals living in small, prison-like cages where some have languished for decades.

Ethical Questions
Humane Society president Wayne Pacelle says it isn't just the physical abuse of the chimpanzees that's troubling. "I think the larger issue is the psychological torment; animals isolated, kept away from others who can give them companionship, fearing what's going to happen next, and animals living in this constant state of confinement."

Hope Ferdowsian of the Physicians Committee says chimpanzees don't have to suffer like this and explains that there are alternatives to the use of chimpanzees in research. "For example, in HIV research, we've learned a lot from human epidemiological studies and ethically conducted clinical trials," she says. "We've also learned a lot about the virus from mathematical and computer modeling. For hepatitis C vaccine we're learning a lot from in vitro or cell-based methods."

Banning experiments on chimps
Both Kucinich and Ferdowsian were on Capitol Hill recently, campaigning for newly introduced congressional legislation that would eventually ban invasive experiments on chimpanzees.

According to Ferdowsian, the Great Ape Protection Act, or GAPA, "would ban all invasive and harmful research on chimpanzees in American laboratories." It would also "release federally-owned chimpanzees, about half of the thousand chimpanzees that are languishing in American laboratories today, to sanctuaries."

But the legislation is not to everyone's liking. John VandeBerg, director of the Southwest National Primate Research Center in San Antonio, Texas, says the use of chimpanzees in biomedical research is essential.

He argues that there are no other animals that can be infected with Hepatitis C virus, Hepatitis B Virus or HIV.

"So in order to develop drugs to treat people who have Hepatitis B, Hepatitis C, particularly, we need to use chimpanzees to determine if the drugs can reduce the level of viruses in their blood and in their livers," says VandeBerg.

While he acknowledges that there is much to be learned from alternative research methods like cell culture - a process by which cells are taken from a living organism and grown under controlled conditions - VandeBerg says they have learned a lot more from research on chimpanzees.

"There are hundreds of millions of people who suffer from hepatitis-B and hepatitis-C, the two diseases which are most important for the moment for chimp research," says Dr. John VandeBerg, director of the Southwest National Primate Research Center.

"For example," he says, "we cannot determine if a drug is going to work in a human being, and be safe in a human being by testing that drug in cell culture models. We must determine first if it's going to work in a living animal that has all the complexities of a human being."
VandeBerg says he and his colleagues go out of their way to use lower forms of animals before experimenting on chimpanzees. "When the research progresses to a stage when the information coming from mice and rats is not sufficient, we may move up to using monkeys. And when monkeys can't give us the answers we need, only then, do we move to the chimpanzee."

Benefiting millions
VandeBerg also points out that the research that's been conducted on chimpanzees so far has already benefited much of the world's population.

"Three hundred and fifty million human beings in the world are infected with Hepatitis-B virus. Three hundred million people in the world are infected with Hepatitis-C virus. That's almost a tenth of the world's population." says Vandeberg. "It would be unethical for us to turn our back on these people and not conduct the research that is so desperately needed to develop the drugs to treat these diseases and the vaccines to prevent them in the future."

Vandeberg also defends his research facility, saying that the animals in his primate research center receive better care than most people in the world. "They live in social groups, they live in indoor-outdoor enclosures, they have heating in the winter and air conditioning in the summer; our chimps even have televisions," he says.

World renowned primate expert Jane Goodall believes using chimpanzees in medical research is "morally wrong and unacceptable".

But such creature comforts don't change the fact that chimpanzees used in medical research may suffer or die, and that's unacceptable to famed primate expert Jane Goodall. She spent decades studying and living among Central African chimpanzees in the wild and now campaigns to protect the endangered species.

"We need to recognize at the outset that what we do to animals - from their perspective certainly, and probably from ours - is morally wrong and unacceptable, and that it's really important to follow through on all these exciting new leads into ways of doing research without using animals," says Goodall.

But John VandeBerg of the Southwest National Primate Research Center says if the proposed legislation to phase out medical research on chimpanzees is passed, scientists like him will have to end their work. "It will be a great tragedy for humanity if research with chimpanzees were stopped."

The Great Ape Protection Act is currently making its way through the U.S. Congress. It has more than 140 co-sponsors in the House of Representatives. Until the measure becomes law, medical testing on chimpanzees will continue to be a highly divisive, and hotly debated, issue.

Travelling is good for cognition

A great article by Jonah Lehrer on how travel expands our minds (and why we go through the hell of getting there) can be found at "Why We Travel" at scienceblogs.com

an excerpt:

...When we escape from the place we spend most of our time, the mind is suddenly made aware of all those errant ideas we'd previously suppressed. We start thinking about obscure possibilities--corn can fuel cars!--that never would have occurred to us if we'd stayed back on the farm. Furthermore, this more relaxed sort of cognition comes with practical advantages, especially when we're trying to solve difficult problems. Look, for instance, at a recent experiment led by the psychologist Lile Jia at Indiana University. He randomly divided a few dozen under-grads into two groups, both of which were asked to list as many different modes of transportation as possible. (This is known as a creative generation task.) One group of students was told that the task was developed by Indiana University students study-ing abroad in Greece (the distant condition), while the other group was told that the task was developed by Indiana students studying in Indiana (the near condition). At first glance, it's hard to believe that such a slight and seemingly irrelevant difference would alter the performance of the subjects. Why would it matter where the task was conceived?

Nevertheless, Jia found a striking difference between the two groups: when students were told that the task was imported from Greece, they came up with significantly more transportation possibilities. They didn't just list buses, trains, and planes; they cited horses, triremes, spaceships, bicycles, and even Segway scooters. Because the source of the problem was far away, the subjects felt less constrained by their local transport options; they didn't just think about getting around in Indiana, they thought about get-ting around all over the world, and even in deep space.

...and in summary:
So let's not pretend that travel is always fun, or that we endure the jet lag for pleasure. We don't spend ten hours lost in the Louvre because we like it, and the view from the top of Machu Picchu probably doesn't make up for the hassle of lost luggage. (More often than not, I need a vacation after my vacation.) We travel because we need to, because distance and difference are the secret tonic of creativity. When we get home, home is still the same. But something in our mind has been changed, and that changes everything.

A Brief History of Pretty Much Everything


via Geeekologie
This is a brief history of the universe and life on earth in 3:12 entirely in flipbook form. It was created by student Jamie Bell for an art class:
This is the final piece for my AS art course, a flipbook made entirely out of biro pens. It's something like 2100 pages long, and about 50 jotter books. I'd say I worked on and off it for roughly 3 weeks.
