The world's poorest have long struggled to borrow. Now, an alternative microfinance model is also making it easier for poor people to save.

Microfinance institutions have provided lending services to millions of the world’s poor people for several decades. But loans must be paid back, and even traditional microlenders are hesitant to lend money to the poorest of the poor—including those living in some of the most remote and unpopulated communities. That’s where the model of village savings and loans associations (VSLAs) comes in, according to a recent Economist article.

The idea is simple: savings, rather than just borrowed money, is key to helping poor people become more stable and less vulnerable. Differing from the better-known Grameen Bank model of microfinance, which provides individual or group loans and operates on credit, a village savings and loan scheme allows a group of community members to pool their savings, lend within the group, and save the interest earned from the loans to disperse to members individually or use for community projects.

This model enables both borrowing capabilities and longer-term savings accumulation for both the group and its members.

CARE International, a humanitarian aid organization focused on fighting poverty, engineered the VSLA model in Niger in 1991. Today, CARE oversees village savings and loan associations in Ghana, Malawi and Uganda. Numerous other non-governmental organizations have promoted village savings groups that serve more than 4.6 million members in 54 countries.

While nonprofits promote the model, the groups themselves are internally managed. Unlike solely credit-based models, group members do not owe repayment to an external bank, but rather to their own pool. Group constitutions are established by members, outlining rules, interest rates, and how savings and interest will be shared. Sometimes transactions, debts and credits are written in basic ledgers, but some groups with no literate members rely on memorization, familiar to those with a culture of oral history, according to Hugh Allen, founder of VSL Associates.

Amid criticism of the effectiveness of traditional microfinance models, as we reported a few months ago, VSLA schemes offer a different path to poverty alleviation.

And for some of the world’s poorest, savings—not a loan— is the golden ticket needed for a better life.

Medic Mobile works with the simplest of cell phones to help provide health care to those far away from their nearest hospital. Photo: Fabiola Coupet/Mercy Corps.

In rural communities around the world, the virtual doctor is in.

The distance between far-flung communities and their nearest hospitals can be fatal. Medic Mobile bridges the gap using a common household item: the cell phone. It’s not the same as a living, breathing doctor, but Medic Mobile comes pretty close, and it does so using a list of platforms that is strikingly similar to what you might find on a smart phone. These seemingly-sophisticated technologies can work on even the most basic of cell phones and computers, just like those found all over the developing world.

Medic Mobile’s Sim Apps, in addition to open-source platforms like FrontlineSMS, OpenMRS, Ushahidi, Google Apps, and HealthMap, allow hospital staff sitting at a computer to communicate with multiple health workers in rural areas. The health workers’ phones are basic, but Medic Mobile uses a tiny parallel SIM card that fits between any GSM phone and a carrier’s cell phone to allow these phones to run the necessary apps. The Medic Mobile website provides a more in-depth description of the many technologies it employs. In a 2009 interview with GOOD magazine, co-founder Lucky Gunasekara described Medic Mobile’s importance:

We can communicate need in real time. Say I am a community health worker in rural Malawi and one of my patients gets really sick. Before this system came along, for a lot of clinics, the patient would die, because even though I have some basic health training as a community health worker, there is nothing I can really do. They're still just as disconnected as the communities they live in. Now with our system clinicians see things in real time and they communicate back.

In addition to saving lives, the program saves time: its website says that in six months, the pilot program in Malawi “saved hospital staff 1200 hours of follow-up time and over $3,000 in motorbike fuel” and cut 900 hours of travel time for antiretroviral therapy monitors by eliminating their need to hand-deliver reports to the hospital.

Since its inception in 2009, Medic Mobile has expanded to Honduras, Haiti, Uganda, Mali, Kenya, South Africa, Cameroon, India and Bangladesh. The platform is adaptable to different situations: it was used in Haiti following the 2010 earthquake to link first responders and locals in need of help. As a result of its successes, Medic Mobile was recently named one of the Top 11 in 2011 mobile health innovators of the year by mHealth Alliance.

The proliferation of cell phones is sparking a revolution in developing-world health care. Innovators from all reaches of the globe have used the near-ubiquitous technology to increase health care affordability and access. By adapting sophisticated platforms to basic devices, they’re turning $15 cell phones into invaluable lifelines.

With a shared currency, entrepreneurs like this Tanzanian vendor won't have to change money when selling their products in other countries. Photo: justCRONO (flickr).

Has the eurozone crisis made shared currencies passe? East African leaders don’t think so, and they’re looking to Europe for an example of what not to do.

Economic integration isn’t a new idea for the East African Community. Its five member states&mdashUganda, Kenya, Tanzania, Rwanda, and Burundi&mdashalready have free movement of goods and labor, thanks to a customs union and, since last year, a common market (a type of trade bloc). According to EAC Deputy Secretary General Dr. Enos Bukuku, a shared currency would build on this by controlling price instability and exchange rate volatility among the states, writes In2EastAfrica. He says this would encourage businesses to invest and spur development in the region.

An EAC monetary union could face many of the same problems Europe has already experienced. Critics point out that the five EAC states’ economies differ greatly in size and scope. Kenya’s GDP is $31,408,632,915, while Burundi, with a fifth of Kenya’s population, has a GDP of $1,610,544,922, according to the World Bank. This could mirror the dynamic between powerful European states like Germany and the EU’s smaller states like Greece, as Tanzanian IMF head John Wakeman-Linn told The Financial Times. But EAC Secretary-General Dr. Sezibera doesn’t think this will be an issue. “If you look at EAC trade statistics, all the partner states have gained. I do not think Kenya will swallow up the other countries; it will only enrich the economic base of the community,” he said in an interview with The East African.

To the citizens who will be affected by these changes, the European Union’s tribulations are probably either unknown or seemingly distant, but EAC leaders are paying attention and believe that they can avoid Europe’s mistakes. At a round of negotiations in Uganda earlier this month, Bukuku said "For the eurozone ... maybe there wasn't well coordinated fiscal policy management and enforcement. If there are benchmarks that are agreed upon, it would be expected that the community would also agree on sanctions and enforcement mechanisms," reports The Christian Science Monitor. He also cited the issue of fiscal discipline and said that many of Europe’s problems are a result of the eurozone countries not having “lived up to what was in the treaty.”

Economists like the World Bank’s Paul Collier warn that a currency union could hurt East African economies, according to allAfrica.com. Others feel it’s simply inappropriate in the current economic climate; The Financial Times cites shrinking regional growth and depreciating currencies as discouraging indicators. But Wakeman-Linn disagrees, telling the newspaper that even if a common currency isn’t feasible, putting the necessary components in place could help East Africa:

“All the things that they need to do to achieve a common currency – integrate financial markets, trade policy, labour markets, capital markets, statistics databases, develop easy mechanisms for exchanging each others’ currencies – all of these things would be extremely valuable and would help develop the regional economy, and so these are things they should do.”

By revealing the cracks in the world’s financial systems, the global financial crisis has provided developing nations with a handy "What not to do" guide. EAC leaders are strong in their belief that a shared currency is possible, even if there are challenges along the way. “The monetary union is a possibility, not a dream,” Dr. Sezibera told The Financial Times. They originally hoped to implement the currency union by next year, a deadline that has proven to be overly optimistic.

With the lessons they’re learned from the euro’s failures, they hope to avoid some of the bumps along the way.

Women farmers in Africa produce over 60 percent of all food crops. CIMMYT (flickr)

Women comprise 43 percent of the world’s farmers. In Africa, it’s 80 percent. Women plant, harvest, process and sell their crops, but men continue to dominate agricultural science and research. This may be about to change.

African Women in Agricultural Research and Development (AWARD) is trying to close the R&D gender gap. Their program fast-tracks female science careers in agriculture, empowering them to contribute more effectively to hunger and poverty alleviation in their own communities - a model that could be replicated internationally.

Although African women produce 60 to 80 percent of food crops, they receive significantly less (5% as of 2008) of the agricultural training and tools available to men, says the United Nations. A 2010-2011 research report by the United Nations Food and Agriculture Organization shows that women could produce 20-30 percent more if they had equal access. This creates a subsequent increase in household income, health, and community food supply. The East Africa Report emphasizes that research is also pivotal in fostering innovation. Without a seat at the table, women cannot influence practices. Who better to innovate than the farmers themselves?

Within a few years, cheap sorghum-based beer might be the newest gift of the Nile to drinkers and farmers alike. Photo: Tattooed JJ (Flickr)

With barley beer priced out of reach and homebrewed banana beer sending people to the hospital, SABMiller is testing a new ingredient for its African alcohol: sorghum.

The giant global beermaker and its subsidiary, Nile Breweries, see an opportunity to expand their business while potentially halving the price of mainstream beer. Thanks to their tweaked recipes and Africa's abundant natural sorghum resource, prices are already falling fast.

A CNN Money article explains that the average American consumes 77 liters of beer annually. In Africa, not including South Africa, the average person only consumes about 7 liters. Because of this, SABMiller sees cheap sorghum beer as an opportunity to "crack a virgin market." Although sorghum is usually used for syrup and cattle feed in countries like Uganda, Tanzania and Zambia, SABMiller's Nile Breweries developed a beer recipe in 2002. CNN explains that by building high-tech microbreweries and micro supply chains sourcing local ingredients, SABMiller stabilizes the price of beer by reducing dependence on international imports, creating a more self-sustained and cheaper market for Africa. The new product is priced 20 percent less than imported barley beer.

This inexpensive yet high-quality beer is becoming popular very fast—nearly 35 percent of all beer in Uganda is now Nile's Eagle sorghum beer, which CNN reported is also sold in Tanzania, Zambia, Zimbabwe and Swaziland. In 2008, Heineken and Diageo followed suit with a sorghum recipe for Ghana, Sierra Leone and Cameroon. Multinationals are racing into an untouched market.

Not only does the recreated sorghum recipe help boost profit for major beer companies, it sustains Africa's economy. According to a study by French business school INSEAD, Nile Breweries added about $92 million to the Ugandan economy and supported roughly 44,000 Ugandans through agricultural, manufacturing, retailing or distribution jobs in 2007. SABMiller is sending a share of this revenue to subsistence farmers at the bottom of its value chain.

"Our affordability model is attractive because it focuses on local crops and creates additional income for farmers and a new profit pool for us without cannibalizing our core product," says Andy Wales, head of Sustainable Development at SABMiller.

As CNN explains, SABMiller's idea of using local ingredients to tap new markets follows that of Coke and Danone. Africa will contain seven of the world's 10 fastest-growing economies by 2015, CNN says, and roughly 200 million Africans will enter the consumer goods market by 2016. Multinationals, such as Coke, Danone and now SABMiller, see vast opportunities in the very near future.

Not everyone thinks SABMiller's tactics will make a mark in Africa's economy. "Africa is still mom-and-pop," said Don Elefson, a fund manager for the Harding Loevner Frontier Emerging Markets Fund, explaining that multinationals will still remain "on the sidelines." But with SABMiller's next steps of using cassava-based beer in Mozambique and Southern Sudan, seeding a Tanzanian barley industry and creating better processors to preserve products while distributing, the company may be on a fast track to meet its long-term goal of halving the price of beer in Africa and tapping a huge new market.

Girls who lack access to sanitary pads may miss up to 40 days of school a year. Photo: Cassandra Nelson/Mercy Corps.

In the United States, missing close to two months of school every year might get you expelled. For millions of women and girls in the developing world, it's a routine.

They lack access to something many modern women in the developed world probably take for granted: sanitary pads. Even when pads are locally available, many girls simply can’t afford them: UPI reports that in South Africa, a pack of 10 might cost $2. In many areas, that is more than a day’s worth of wages, according to North Carolina State University. Girls who don’t have access to pads during their period miss school due to embarrassment, fear of being teased and cultural taboos. Some try to use newspaper, old rags, or mud instead, methods that pose health risks and barely even work.

Many girls fall behind in school or drop out entirely as a result of this simple problem. For a variety of reasons, it’s one that’s not often discussed openly. So how do you solve a problem that no one wants to talk about? Fortunately, many businesses and organizations are looking for solutions.

At the same time that FemCare, a part of Procter & Gamble, sells Always-brand sanitary pads in U.S. supermarkets, it seeks to provide the same products to African schoolgirls. But the problem is thornier than you might expect. Beyond a simple lack of supplies, schools also often lack the facilities that allow girls to use feminine products in the first place. They need private spaces to change pads during the day and running water to wash their hands. To address this, FemCare built bathrooms and constructed water pipelines to schools, says the New York Times. They also provide disposal containers and have taught teachers how to incinerate the waste. Of course, there’s something in it for P&G, too: they hope that girls in Africa will become lifelong users of their products.

The problem has also inspired a great deal of innovation as individuals attempt to design new products that can be manufactured more cheaply and sustainably than name brands. Swedish university students used water hyacinth, an invasive species that chokes off Kenyan water routes, to create the Jani pad. In a double whammy, It’s both biodegradable and made from a seemingly endless resource that no one likes.

Starting in 2008, Sustainable Health Enterprises (SHE) tried another tack: it designed a manufacturing process that anyone could replicate. Their award-winning approach makes pads from readily available materials like banana-stalk fibers, which are then processed on inexpensive machines that local people can purchase. Hopefully, SHE’s innovations will better enable people in developing nations to start their own businesses to manufacture the pads. This also lets the finished product be tailored to the needs of women and girls from diverse cultures.

Other projects are born from the creativity of local entrepreneurs. Makapads, invented by a university professor in Uganda, are made from papyrus and waste paper and produced on locally manufactured machines, reports IRIN.

Often, trying to solve a problem in the developing world is like trying to solve a Rubik’s cube. Each group toggles the pieces a bit differently. Hopefully, in the end, someone makes them all line up.

New organization Solar Sister is empowering women in rural Africa to star their own solar lamp businesses. Photo: IvanClow (flickr)

A new organization seeks to light up the night in rural Africa by putting a twist on an all-American idea: the Avon lady.

Night in rural Africa is a night much darker than that to which the developed world is accustomed, as many communities lack electricity. In rural Uganda, the number is as high as 95 percent, as Katherine Lucey told Dowser.org. Without electric light, people must rely upon kerosene lamps, which are expensive and belch toxic fumes.

These create a bevy of problems, especially for women. Girls are often expected to help with chores when they return home from school and don’t have time to do homework until after dark. Either they sit inhaling fumes and burning up cash with the family’s kerosene lamp, or in many cases, they simply don’t study at all. Solar lamps solve this problem by extending the work day.

For years, Africans have had a big problem with solar power: it breaks. In an interview with Dowser.org, Solar Sister founder, Katherine Lucey, said that in her previous work with a nonprofit, the solar systems they installed in rural areas had a 50 percent rate of failure after just one year. Traditional solar power can be a hard sell for poor communities — it saves money in the long run, but it's pricey at first, and many solar panels often fall apart over time due to improper maintenance. The new lamps that Solar Sister uses are small, portable, and don’t require technological know-how to use — you simply place the lamp outside during the day, it absorbs the sun’s rays, and when night falls you turn it on.

Solar Sister uses a microconsignment model, meaning that its entrepreneurs don’t pay for their lamps until they actually sell them. If they can’t sell the lamps or decide they don’t want to, they can return them to the organization without loosing any money. It’s a low-risk endeavor that has so far empowered 107 women in Uganda, Ghana, and Sudan. Normally, these women wouldn’t have had enough money to create a business.

The lamps range from $15 to $50 at first, a large investment for most families. But, an average family spends about $2 a week on kerosene, so a family could save up to $85 a year just by buying a lamp, says TriplePundit. Solar Sister estimates that its entrepreneurs can actually double their households’ incomes while decreasing their household expenses by 30 percent. Some of the lamps can even act as cell-phone chargers. Not only can women with these lamps charge their own family’s phones; they often bring in extra money by charging neighbors’ phones. Otherwise, they’re left to travel to nearby cities whenever a phone goes dead.

The women who participate in Solar Sister can seem pretty ecstatic about their new businesses, as you can see in this clip below of Viola, one of the women selling solar lamps in eastern Uganda.

Solar Sister currently operates in Uganda, Rwanda, and South Sudan, and hopes to shine a light on other parts of Africa soon.

The Economist

The Economist

Since 2001, the budding economies of the BRICS (Brazil, Russia, India, China and South Africa) have dominated global financial headlines. But looking back, it turns out some of the so-called “African lion” economies (Angola, Nigeria, Ethiopia, Chad, Mozambique and Rwanda) were just as fierce.

Six of the 10 fastest-growing economies in the world hail from the “forgotten continent” of Africa — putting up annual average GDP growth rates of around 8 percent or more from 2001-2010. The monumental rates have even earned these sprinters a spot next to “Asia's tigers” of the 1980 and 1990s — Making Africa one of the fastest growing regions in the world, according to The Economist.

Over the past decade, sub-Saharan Africa’s real GDP growth rate jumped to an annual average of 5.7%, up from only 2.4% over the previous two decades. That beat Latin America’s 3.3%, but not emerging Asia’s 7.9%. Asia’s stunning performance largely reflects the vast weight of China and India; most economies saw much slower growth, such as 4% in South Korea and Taiwan. The simple unweighted average of countries’ growth rates was virtually identical in Africa and Asia.

That said, in the next five years Africa is set to take the top spot from Asia as the fastest-growing region in the world, writes The Economist. "Standard Chartered forecasts that Africa’s economy will grow at an average annual rate of 7 percent over the next 20 years, slightly faster than China’s."

Ironically, much of Africa's growth can be attributed to China's investment and demand for raw materials in the region. And more recently, another of the BRICS, Brazil, has been competing for assets in Africa, writes Fast Company.

The Economist also notes growing success in Africa's manufacturing sector, which Standard Chartered predicts will become "significant."

Even with challenges such as political instability, corruption and weak rule of law, the African lions have been able to compete with the economic prowess of the Asian tigers.

But before Africa's growling economies can dream of surpassing Asia's roaring ones, those structural problems will have to be fixed.

"Without reforms," The Economist says, "Africa will not be able to sustain faster growth."

Youth unemployment is high in Uganda: An estimated 80 percent of 15-24 year olds are unemployed. Photo: johnhayes5032(flickr)

A recent Christian Science Monitor article takes a look at one school's approach to helping young women address the challenges of poverty and unemployment in Uganda.

With a median age of 15, Uganda has the world's youngest population, according to a 2008 World Bank report. It also has the highest youth (ages 15-24) unemployment rate: 83 percent. It's common to find 20-somethings with law and business degrees stocking supermarket shelves.

The article points out an all girls school in Kagdai, Uganda, that is trying to break this cycle. Sponsored by the non-profit Uganda Rural Development Programme the school is choosing to fight poverty by unleashing the potential in 250 of Uganda's poorest girls. The URDT's mission statement says that they wish to give the girls the tools, and encouragement they need in order to become the "creators of their desired circumstances."

To do so the school uses a two-generational approach that helps both the future generation (students) as well as the current generation (parents). So, the daughters team up with their parents and figure out what part of their lives they want to change then with the help of their teachers, together they make that change happen. Whether this is learning to grow enough crops to feed their family, or building a cleaner latrine, the school reminds the girls that they are their own number one resource for change.

Thanks to URDT's encouragement these girls are creating both jobs and change for themselves. As the Christian Science Monitor says, the students are making "yes we can more than just a campaign slogan from a far away land."

Urban overcrowding, like that seen here in Kampala, has lead many Ugandans to build on top of ecologically important wetlands. Photo: kloppster (flickr)

They arrive during the night with their construction tools. Some come with hired security guards. These are the wetland encroachers of Kampala, hoping to claim land before the watchful eye of the National Environmental Management Authority notices and evicts them.

Poverty is compelling many people to build on the wetlands as population growth and urbanization increase land competition. The construction destroys the land's ecological value, Uganda's The Monitor reports.

Uganda's wetlands filter water and prevent destructive flooding downstream. They are also a source of material for profitable products like papyrus. Wetlands provide employment for 2.7 million Ugandans in a country where just five percent of the total work force has a consistent income.

Uganda was the first African country to develop a national wetlands program. The government has spent millions of dollars and partnered with the World Resources Institute (WRI) to develop an information system to track wetland use. Also, Ugandans who build on wetlands without permits are subject to fines and evictions.

The WRI and the Ugandan government are concerned that the services and products wetlands provide, and on which many poor households depend, are at risk. But, despite Uganda's pioneering status in wetlands management, the country faces many trade-offs as it balances land needs with the desire to preserve the ecosystem and alleviate poverty.

The following post is from One Table, a Mercy Corps campaign to fight world hunger by investing in the world's women.

Today almost a billion people worldwide are unable to buy or grow enough food to avoid malnutrition. That's 120 million more than were hungry in 2006.

What happened? Basically, the world saw dramatic spikes in food prices. But there were many underlying causes of what's known as the global food crisis:

• Drought and other climate-related problems that resulted in smaller harvests
• Changing diets — rise of the middle class in India and China and an increased demand for food, especially meat, which requires large amounts of grain to raise
• Diversion of crops from food production to the production of biofuels
• High fuel prices during 2008 — if it costs more to transport food, prices go up
• Declining investments in agricultural productivity — total agriculture development aid to poor countries plunged from $8 billion in 1984 to $3.4 billion in 2004. At the same time, the developing world's cities have been ballooning with people who do not grow any of their food
• Export bans and restrictions last year in several major grain-producing countries like China as governments sought to lower food prices for their own citizens, with the result of reducing the global supply on hand.

While food prices have come down from their highs of 2008, they remain substantially above historic levels. Many economists feel this trend, which most severely affects those who can least afford it, is likely to continue for some time.

The economic, health and societal costs of the global food crisis have been severe. One of the first things Mercy Corps did to figure out how and where to direct our efforts was to survey the communities where we work. We discovered that within communities Mercy Corps serves, roughly 70 percent of income is spent on food, and 80 percent of the population had been affected by rising food prices over the past year. The survey also confirmed something we already suspected: that families were coping with higher prices by eating fewer meals, selling off household belongings, going into debt and removing children from school so that they can work.

In addition to being a record year for food prices, it's also been a record year for our food security team, allowing Mercy Corps to aggressively respond to this crisis. We now have 17 programs in 13 countries designed specifically to respond to this on-going problem. Through support from donors including USAID, the Bill & Melinda Gates Foundation, the Gap Foundation, the Hunger Site, and private individuals, our Food Crisis Response employs a strategy designed to ensure that the groundwork for increased prosperity in the future is laid — even while addressing the immediate problem of accessing sufficient food.

Food distributions, much of which are specifically targeted to improve child nutrition, are taking place in Tajikistan, Kyrgyzstan and Zimbabwe. Meanwhile, in the Central African Republic, India, Indonesia, Liberia, Nepal, Niger, Somalia, Sri Lanka, Uganda and again Zimbabwe, Mercy Corps is helping hungry households to access food by providing employment opportunities, agricultural training and inputs (such as seeds and tools), and helping people establish and grow small businesses.

Combined, these programs are reaching almost 1.5 million individuals who have been directly impacted by higher food prices. Overall, Mercy Corps’ Crisis Response will lead to a sustainable increase in income for these people, leading in turn to greater food security over the long-term.

A new mobile technology is helping battle HIV in Biwindi, Uganda where most people walked days through the tough terrain to get medical care. Photo: youngrobv (Rob & Ale)

Could you imagine having to walk a full day to get medical care, and then wait weeks to learn your test results? Well, that was the reality for people in Biwindi, Uganda until just a few months ago, the BBC reported earlier this month. Now, new technology is bringing medical testing to people living in the middle of Uganda's forests.

This new technology is called the PointCare NOW machine. It's a portable blood-testing device that analyzes what's wrong with you within 10 minutes. It's also the first portable machine that can diagnose HIV within minutes. Developed by PointCare, a U.S.-based company specializing in diagnostic equipment for developing countries, the machine easily fits in the trunk of most vehicles.

PointCare's founders Petra Krauledat and Peter Hansen came up with the idea for a portable, durable HIV-testing device on a trip to southern Africa a few years ago. Krauledat and Hansen say the battery-powered machine has a 180,000-day lifetime.

PointCare is piloting the technology in rural Uganda, where the need for fast and comprehensive medical care is obvious. One in 20 Ugandans is infected with HIV, according to Avert, an international AIDS charity. One in 12,500 people in Uganda is a doctor. And 70 percent of the population lives in rural areas.

Dr. Williams, a physician from England that opened a small hospital in Uganda, sings the praises of the PointCare NOW machine. He tells the BBC:

"I started a testing centre in the hospital, then the mobile testing services, and then, once we had access to drugs, developed a treatment program. Now our death rates from HIV are very low. We're able to diagnose it early, manage it early and keep people living with HIV fit and well. Over a reasonably short period of time, we've been able to change HIV from being a death sentence into something that people can live with and lead productive lives."

Condoms prevent transmissions of disease, and could be key to population control. Photo: Rampant Gian (flickr)

CIA director Michael Hayden recently identified one of the biggest threats facing the U.S., something that occurs over 215 million times a day — sex.

“Population is the essential multiplier for any number of human ills," Hayden said recently. He said overpopulation in the poorest parts of the world is causing global political instability and extremism, climate change, and the food and fuel crises.

In the 1970s, environmentalists frequently discussed the problems of overpopulation, but in the last 30 years, rigid population control has been condemned.

Robert Engleman, vice-president at the Worldwatch Institute and author of the new book More: Population, Nature and What Women Want, says that after China's controversial one-child policy, "Environmentalists came to realize how complicated and sensitive this issue was.”

As food and fuel prices rise, so do concerns that the planet’s limits are finite. Population growth has slowed in developed countries, but is still rising in much of the developing world. With climate change forcing a fresh look at overpopulation, Engleman’s new book argues that “the key to limiting population growth is to give control over procreation to women.”

What Engleman is suggesting is not feminism, it’s just common sense. He says that even in societies with traditionally large families, when women gain control over family sizes with contraception access, birth rates shrink.

Fifty-year-old Linganni, who earns $2.50 a week sweeping streets in Burkina Faso, would certainly agree that too many children and not enough food is a problem. In an article that discusses how the food crisis is hitting women the hardest, The Washington Post describes how her 25 children share one meal a day. And Linganni always eats last.

In his recent article "What Condoms Have To Do With Climate Change", Time's Bryan Walsh suggests the best policy for the U.S. would be “vigorous foreign aid that helps make contraception safe, reliable and accessible in every country — too often women in the developing world who want to use contraception, can't get it.”

Contraceptive aid from the U.S. may be a difficult sell, considering that Americans are still obsessing over abstinence-only sex education and holding father-daughter purity balls. And around the world, contraception is often taboo, and the decision whether to use it is up to the man.

One solution is to support forms of contraception that give women control and are invisible to men, like the Pill or IUDs. But whatever the approach, women need to have control over the number of kids they have. Population control will only happen, Engleman reminds us, when "women are in charge."

Plastic bags have long been associated with litter and waste. The world uses tens of billions of plastic bags every year – bags that end up hanging from trees, traveling along freeways, escaping garbage cans and waste dumps.

Plastic-bag recycling rates are extremely low – about 1 to 3 percent worldwide, according to Reusablebags.com.

While plastics have helped us in many ways – medical advances, for one – by now we are seeing an increasing amount of wasteful uses. The mass production and ubiquitousness of plastic bags has hit a nerve in many developing countries. Lawmaking bodies in every region of the world have begun to regulate the use of plastics — and some are even banning the use of plastic bags outright.

Here's a partial list:

India. In August 2005, the state of Maharashtra initiated a bag ban after bags "blocked sewage and drainage systems during record monsoon rains," according to The Guardian. "Flooding and landslides killed more than 1,000 people in the state.” Anyone seen with a plastic bag can be fined 1,000 rupees, or about $25.

Kenya. The East African nation has enforced new regulations banning production and distribution of light-density bags, according to Nairobi's Business Daily (as reported by allAfrica.com). Three years ago, Kenyan researchers had appealed for a ban, and Nobel Peace Prize winner Wangari Maathai had argued that plastic bags can lead to malaria, because discarded bags left outside can fill with rainwater and breed disease-carrying mosquitoes.

Uganda and Tanzania. Kenya's neighbors also banned the use of all disposable one-use plastic bags nationwide. One Ugandan blogger wrote that “This seemingly radical step has a direct connection to human health and also to environmental well-being of citizens across Africa. Apart from the fossil fuel usage needed in their production, plastic bags have a remarkable ability to pollute across borders.”

China. Authorities announced that by this June, one-use plastic bags will be outlawed in the hope that residents will return to their old habit of using cloth bags and baskets. "Beijing residents appeared to take the ban in stride, reflecting rising environmental consciousness and concern over skyrocketing oil prices," reports National Geographic.

Some developed nations also have taken drastic steps to reduce the impact of plastics. Ireland, for example, imposed a 33-cent tax in 2002. It worked quickly to depress demand. According to the New York Times, the use of plastic bags dropped 94 percent within weeks.

Access to cheap energy underpins modern societies. Finding enough to fuel industrialized economies and pull developing countries out of poverty without overheating the climate is a central challenge of the 21st century. — Michael Wines, New York Times

Sub-Saharan Africa is perilously close to an energy crisis.

Massive drought across Kenya and Ethiopia has slowed hydropower production to a trickle. Rickety electrical infrastructure in South Africa and elsewhere has led to huge rolling blackouts expected to go on for years in some regions, according to the International Herald Tribune. The World Bank says Africa's "lack of reliable power has already begun to hamper the region's development." The worst-hit African economies have seen economic growth slow by more than two percent.

Energy shortages impact a broad array of activities in these countries. In Uganda, for instance, power shortages are causing gas stations to run low on diesel. The environment suffers as well. For the 80 percent of sub-Saharan Africans who lack electricity, Inter Press Service News Agency says:

The destruction of natural vegetation could lead to desertification when there are no water catchment systems to feed rivers and streams. And when there is no water, the population in such an area suffers in many ways. They cannot plant crops and their animals die.

Solutions to the energy crisis still seem far off. India and China have begun funding new power generating facilities — in one instance providing Zambia's energy producer, Zesco, with $1.2 billion for upgrades and new capacity creation. But the sheer size of the problem suggests a multinational approach. "The best answer, most experts consulted agree, would be for nations to cooperate on regional power solutions," the New York Times reports. "One or two large regional plants, they say, could supply power more cheaply and efficiently than dozens of smaller ones."
