In rural Kenya nearly everyone uses kerosene as their main source of power. For those living on less than $1 a day — as about half the population does — this expense takes away a significant portion of their income. Kerosene costs the average African family almost $100 a year, according to the blog White African. And that's why Evans Wadongo's goal of providing solar-powered lanterns to rural Kenyans is so admirable.

In fact, Evans Wadongo and his work with solar lanterns was featured in a recent "CNN Heroes" video. In the video, Wadongo shows how these simple lanterns can do much good for rural Kenyans.

Families with solar lanterns can now spend the money they used to spend on kerosene on necessities like food and medicine. The lanterns are also much better for studying at night. Kerosene lanterns smother kids in smoke and can be harsh on their eyes because the light they give off is so dim. Solar lanterns provide brighter light without all the pollution — giving both kids and the environment a brighter future.

Thanks to Wadongo and his nonprofit sponsor Sustainable Development for All-Kenya, 10,000 of these lanterns have been distributed to rural Kenyans for free.

Cassandra Nelson helps to distribute high-energy biscuits to locals at a hospital in Port-au-Prince. Mercy Corps

Yesterday the banks reopened in Haiti for the first time since the earthquake rocked the small island on January 12th.

Mercy Corps' spokeswoman Cassandra Nelson, who is on the ground in Port-au-Prince, stressed the importance of the banks reopening in her latest post on the Mercy Corps blog. "This means a lot to the aid effort, because there are a lot of people in Port-au-Prince who have some money — maybe not a lot — but they were having to live on handouts simply because they couldn't access their money." Without cash on hand, even wealthier Haitians were forced to seek handouts while the banks were closed.

As cash became more readily available throughout the day, Nelson saw the street economy reinvigorate from the rubble of damaged store fronts. Hawkers selling bananas and mangoes are helping restart the flow of food and resources within the country, allowing aid agencies to focus on those who are most in need of help.

Thousands of Bangladeshi environmental refugees migrate to Dhaka every year as a result of climate change. Photo: uncultured (flickr)

Big cities are likely to strain under the weight of "environmental refugees" as climate change takes effect, according to a recent story in The New York Times. The story looks at the capital city of Bangladesh where three million people came from rural areas hit by natural disasters.

Dhaka is the last resort for people like Mukhles Rahman, who have lost their homes in floods and other natural disasters. “We are trying to find another place to go, because all the land back home is dissolving,” Mukhles said to the Times, “But there aren’t jobs in other cities or villages.” However, Dhaka's already scarce resources like water, electricity and waste disposal are being stretched by the influx of environmental refugees. Like Mukhles, half of Dhaka's 12 million residents already live in slums that lack basic sanitation and drinking water.

Experts say that climate change is likely to cause more severe and frequent storms over the coming years, says the New York Times. Which means that that that even more people will become environmental refugees.

Haiti has just received another powerful blow. A powerful 7.0-magnitude earthquake rocked Haiti's capital on Tuesday, devastating a country that has seen more than its share of disasters both man-made and natural over the last few years. The news reports trickling in paint a bleak picture of almost unimaginable ruin.

I was privileged to witness some amazing progress in this tiny country that has long carried the dubious distinction of being the poorest nation in the western hemisphere during my annual and semi-annual trips to the island nation since the election of a new president in 2006. Paved roads and bridges had begun to appear across raging rivers that kept villages isolated. In the small community of 40,000 where most of my work took me, Engineers Without Borders drilled and installed seven clean water wells that dramatically lowered the infant mortality death rate. In a community that had once had just one Cuban-trained health worker who functioned without medicine or equipment, a small staff of doctors and nurses began to provide health care. A fragile sliver of hope had begun to take root.

This earthquake has devastated a country that does not have the resources to recover on its own. Mercy Corps’s has dispatched a response team to rush critical supplies and other urgent assistance to survivors. More staffers will arrive in the coming days.

As more aid workers arrive, they will face huge challenges. Haiti's international airport has just one runway and no taxiways, so airplanes that land there have to do a U-turn at the end of the runway and taxi back to a parking space. I can imagine that right now, that one runway and the airspace around Port au Prince is busier than a Los Angeles freeway. On the ground, the Mercy Corps team may find that accommodations are sparse or non-existent. Reports indicate that even major buildings in the capital city have been heavily damaged or destroyed. Security will also be an issue. The United Nations peacekeeping forces have provided the most reliable security in the country, but they themselves have been devastated by the death and injury of key personnel. Food and safe drinking water were never abundant, but now they will be even scarcer. Over the coming weeks and months Haitians will face tremendous obstacles to recovery.

Thankfully, the professionals at Mercy Corps have seen all of this before. They have a long history of helping earthquake survivors in other countries: Peru, China, Pakistan, and Indonesia. I have no doubts about their capacity to provide the best possible support in this situation. Several people have asked how they could best help with Mercy Corps’s effort. Really, the best way anyone could help is to make a cash donation to the Mercy Corps Haiti Earthquake Fund. As a matter of policy Mercy Corps does not use volunteers or donated materials like clothing from the general public in their relief efforts.

With a combination of generous donations and Mercy Corps' tremendous professional resources we can help Haiti survive this devastating body blow and replant the small seeds of hope that I saw grow there over the past few years.

China's carbon-capture technologies help reduce emissions from coal plants. Photo: ishmatt (flickr)

At first glance, China appears to be exacerbating global climate change. The world's most populous country is the fastest growing industrial economy and the single biggest source of carbon emissions.

On the other hand, China may be helping green the world by making environmentally friendly technologies more affordable, says The Wall Street Journal.

China's vast market and economies of scale are bringing down the cost of solar and wind energy, as well as other environmentally friendly technologies such as electric car batteries. That could help address a major impediment to wide adoption of such technologies: They need heavy subsidies to be economical.

In other words, manufacturing anything in China makes it cheaper, and that applies to green technologies, too. That's been a major factor in the 30-percent drop in the price of solar panels over the past year, reported NPR.

The WSJ goes on to note that the country's research into carbon-capture technologies is also cutting-edge, working on procedures that could cut down on emissions from coal plants by storing some of the carbon produced underground rather than releasing it into the atmosphere. Manufacturers in developed countries are already interested in how they can apply it to their own facilities.

It's hard for any country to make the switch to greener energy sources, but if China succeeds in fostering innovation and cutting technology costs, the process could make the transition easier for countries all over the world.

Jared Diamond praises Chevron's environmental stewardship in Papua New Guinea. Photo: Arthur Chapman (flickr)

From Michael Moore to Jonathan Safran Foer, American liberals love to criticize corporations for violations on everything from the environment to human rights to animal rights.

But in some cases they're dead wrong, writes Jared Diamond — an American liberal himself. In a recent New York Times Op-Ed, he argues that big corporations can be a force for good in the fight against climate change, simply because they also stand to benefit by preserving the resources they depend on and reducing their costs through lower consumption.

Diamond draws on examples from three companies: Coca-Cola, Wal-Mart, and Chevron. All three are working to protect the environment in different ways for their own reasons. Coca-Cola depends heavily on water resources and is working to make its plants water-neutral, while Wal-Mart is making its operations more energy-efficient and reducing packaging waste. Chevron, on the other hand, practices a degree of environmental stewardship on the land it owns overseas that Diamond believes is superior to government stewardship of many national parks.

Why would these companies take on such projects? Diamond explains:

Lower consumption of environmental resources saves money in the short run. Maintaining sustainable resource levels and not polluting saves money in the long run. And a clean image — one attained by, say, avoiding oil spills and other environmental disasters — reduces criticism from employees, consumers and government. [...] [I]n the long run (and often in the short run as well) it is much more expensive and difficult to try to fix problems, environmental or otherwise, than to avoid them at the outset.

Diamond readily admits that not all big businesses are so admirable. But he maintains that when working to stop climate change, activists should focus less on working against corporations, and more on working with them to help them realize how much their own economic interests can be aligned with environmentalists' goals.

Reuters reports that despite the recession, American consumer spending on products that are considered "green" has in fact been going up.

U.S. supermarket sales of environmentally sustainable or "ethical" products — from energy-efficient light bulbs to organic produce — will rise about 8.7 percent in 2009 to nearly $38 billion

Reasons behind going green range from personal health to global warming, but Scott Bearse, of the financial consulting group Deloitte, thinks there may be more to it. He tells Reuters, "[t]he financial crisis reminded people of the unintended consequences of collective behavior."

Malawi's economy has deep roots in the small family farms that pepper its landscape. But farmers often can't earn enough from cash crops like tobacco, sugarcane, peanuts and tea.

The Clinton Hunter Development Initiative (CHDI) hoped to change this when they started working with rural Malawian farmers in 2006. As they explain on their website, they encouraged the farmers to grow soy instead of peanuts, which is more nutritious, gets better yields, and is easier to grow.

In one particularly impoverished district, CHDI also worked with a group of local farmers to build a large commercial soy farm. Collectively, the farmers could get a better deal by buying in bulk, which drove down the price of seeds, fertilizer and irrigation tools. CHDI also used the farm as an informal classroom, showing locals how the different cultivation techniques were used.

After only two full years in the country, CHDI reports that for many farmers, harvests have more than doubled under the new system, with income not far behind. One of these farmers shares her story in the video below.

In a country as poor as Malawi, where an estimated 53 percent of the population lives on less than $1.25 a day, that extra income provides farmers with many opportunities that had previously been out of reach.

Iraq's Marsh Arabs have coexisted with the wetlands' unique ecosystem for 6,000 years. Photo: Dr. Michael Izady, Ph.D. (flickr)

Southern Iraq is home to one of the largest wetlands in the world, where the tributaries of the Tigris and Euphrates meet. But a three-year drought in the Middle East, along with dams and water projects in neighboring countries, has left southern Iraq with a serious water shortage, reports the BBC.

For 6,000 years these wetlands have been home to people called Marsh Arabs. They made their huts out of the marsh reeds, ate fish they caught in the waters, and sold the milk and cheese they made from water buffalo milk, explains the LA Times. (A beautiful slide show of Iraq's marshlands and the Marsh Arabs accompanies the The LA Times article.) But now these wetlands are roughly 30 percent of their former size, says the BBC, and they are continuing to shrink.

The marsh's dropping water levels have devastated the wealth of the region and the livelihoods of the Marsh Arabs. Jassim Asadi, of the nonprofit conservation group Nature Iraq, tells the LA Times the marshes used to supply two-thirds of the fish consumed in Iraq. Now people buy bottled water and frozen fish imported from Iran. “It is an economic disaster,” Asadi says.

Though the drought is "the most immediate cause" threatening the wetlands and their inhabitants, regional water politics cannot be ignored, the BBC says. The Tigris and Euphrates flow through multiple countries, and the rivers are the main water source in the area. A BBC video helps break down the situation:

About 70 percent of Iraq's waters originates outside the country, in Turkey, Syria, and Iran... These countries already have ambitious damn and irrigation projects, limiting how much is left for Iraq. And yet more damns are planned — further reducing the flow into the marshes.

Some scholars and politicians remain hopeful that diplomacy and cooperation amongst the different Middle Eastern countries will allow for more equitable water management. But as things stand now, there is no immediate fix on the horizon.

It should be no surprise that armed conflicts force millions of people from their homes each year. In fact, 4.6 million people were displaced by conflict and war in 2008. But I was shocked to learn that the number of people displaced by climate change is four-times greater than those displaced by conflict. That's about 20 million people — roughly the population of Australia — that have been forced to relocate because of natural disasters like flooding, earthquakes and storms.

This figure comes from a joint study by the United Nations Office for the Coordination of Humanitarian Affairs and the Internal Displacement Monitoring Centre and is the first large-scale look at how climate change is effecting human populations. It provides data on exactly how carbon emissions have affected human lives, and it offers a somewhat harsh glimpse into what will happen if the situation is left unchecked.

The Indus River has the potential to provide hydroelectric power to millions - who will hold power over that power is what's causing a logjam. Photo: Michael Foley (flickr)

India and Pakistan have both vowed to build hydroelectric dams along an upper branch of the Indus river, only 70 kilometers apart from each other. Two new hydroelectric power sources would seem like good news for these energy-hungry economies, but there's a catch. According to the terms of the 1960 Indus Water Treaty between the two countries, there's only space for one hydroelectric plant in this part of the long-disputed Jammu and Kashmir valley —
and that's the plant that's completed first.

As the race heats up — India has forecast completion for 2016, and Pakistan one year later — Pakistan hopes to edge past India's projected finish line by hiring on Chinese companies to speed up progress.

So what else is at stake in this standoff? Experts, on the condition of anonymity, recently told The Rising Kashmir Daily Newspaper that Pakistan is reaching out to China to give them an edge over India and compensate for their geographical disadvantage, saying,

Pakistan, being the lower riparian state, faces geographical disadvantage. It fears that India's Kishenganga project will have a devastating effect on its hydro-power plans, besides adversely affecting 1,33,209 hectares of agricultural land in Pakistan administered Kashmir. To stem these fears it has signed up with Chinese companies to complete the project and secure priority rights for the river.

A recent Ground Report article regarding SAAMA News correspondent Ibrahim Malick’s report that at least 20 different UN bodies concur that India and Pakistan are the two likeliest combatants for any near-future water war further illuminates what's at stake in the ongoing Indo-Pak water disputes. Ground Report is quick to point out that these two countries are both nuclear-armed, making the situation, and the potential global consequences, all the more serious.

Telltale precursors to this potential water war are already abundant on both sides of the border, including the unambiguous recommendation by the Pakistani Urdu press for war as a solution to the problem. India, in a more circuitous approach, is enforcing "punishment through water"on Pakistan for their lack of action regarding the recent terrorism attacks in India. Clearly, the prospect for a quick, effective resolution is grim.

As Indus water commissioners from India and Pakistan continue to meet in hopes of resolving issues relating to water resources and hydroelectric power generation in the region, the true losers in the South Asian water wars may end up being the forgotten residents of the very valleys the Indus River and its tributaries flow through.

According to The Bombay News,"electricity remains a distant dream for the residents of the Gurez valley of Jammu and Kashmir despite ample water resources existing in the region." Even though the Kishenganga hydroelectric plant is being built in the Gurez valley, the power from the plant will be transmitted to other, more populous and politically influential Indian states such as Himchal Pradesh, Punjab, and Uttar Pradesh.

Shazia Tabasum, a student and Gurez valley resident, told The Bombay News, "[t]here is so much water here. The government has to take steps to put an end to the power crisis. The electricity is supplied through diesel generators. As long as diesel is there we get electricity, but if the diesel goes out of stock, we live in dark and have to wait for fifteen days to one month for the next stock to reach our place."

Unless the Indian government responds to pleas like these from local residents, they'll have to continue getting by with two to three hours of diesel-generated electricity a day. And by the looks of it, the government has its hands full making the power available in the first place.

Does your neighborhood influence your driving habits?

A University of California at Davis study has found that neighborhoods boasting corner stores, restaurants, coffee shops, hardware stores and other small businesses inadvertently encourage residents to run their errands by foot, rather then by car. About 87 percent of respondents that live less than .5 miles from a grocery store said that they chose to walk instead of drive about six times a month. In contrast, about a third or respondents from less walk-friendly neighborhoods said they walked to complete a single errand in a month's time.

When you add it all up, people living withing walking distance of stores end up driving 42 percent fewer miles than their car-dependent counterparts. Grist points out the importance of this reduction on a global scale. If more people lived in walk-friendly neighborhoods, they would drive fewer miles, and thus, reduce carbon emissions.

Four years ago, a petrochemical plant on the border of China and Russia spilled 100 metric tons of the toxic chemicals into a tributary of the Amur River. The river is the main drinking supply for a town in Russia named Khabarovsk, and it put hundreds of thousands of lives at risk.

Naturally, Khabarovsk turned to Moscow for help. But they also contacted a group of friends in Portland — including my dad.

My dad, Thomas Benke, has been involved in the Portland-Khabarovsk Sister-City Association, or PKSCA, for many years. And his actions after the toxic spill showed me that sister-city associations can be a means for not only cultural exchange but also serious global cooperation.

PKSCA implements a wide reach of humanitarian programs in Khabarovsk that include solid-waste management, emergency services, educational exchanges, hospitals, orphanages, and village schools. And it, along with Oregon Fujian Sister State Association (OFSSA), has responded to disasters such as chemical spills and earthquakes. My dad has volunteered for both. One of his main motivators has been to help preserve the environment. (He holds degrees in chemical engineering and environmental law.)

There is an undeniable synergy between a clean environment and economic development. The old idea that there must be some trade-off between economic development and environmental protection in developing economies is gradually being replaced by the realization that the foundation of economic development — a healthy workforce — thrives on clean air, clean water and an unpolluted landscape.

My father explained to me that soon after the spill in Khabarovsk, he traveled there to deliver and introduce a Gas Chromatograph, a device for testing drinking water in disaster areas. The device was purchased by the City of Portland. In May 2007, PKSCA followed up by inviting two chemists from the Vodokanal (Khabarovsk Water Bureau) to work with the Portland Water Bureau and the Oregon Department of Environmental Quality. Most importantly, PKSCA set up a training session at SRI Instruments in Los Angeles — the company that built the Gas Chromatograph. SRI Instruments' contribution was substantial — they built a specialized device that could detect the contaminants in the Amur River and provided free repair for the device.

Not only did PKSCA quickly respond to the water crisis in Khabarovsk, but by providing further training sessions in the United States, they also sustained and fostered a stronger more informative relationship between Portland and Khabarovsk officials, as well as sister-city board members.

On May 12, 2008, an 7.9 magnitude earthquake struck China’s Sichuan Province, killing tens of thousands of people and displacing nearly five million. Immediately, Fujian Province requested assistance from its Sister State, Oregon, for whatever aid they could provide. Below, Thomas described the international and OFSSA response to the crisis.

The world responded with cash and supplies. The people of Oregon donated cash generously through several local and international non-profit organizations. The Oregon-Fujian Sister State Association, because of its unique relationship with Fujian Province, resolved to do more — to donate emergency response tools that would leverage Sichuan Province’s capacity to respond.

The pre-existing relationship of trust between the two jurisdictions allowed Fujian province to request help from Oregon. The Sister-Province relationship made all the difference — we were able to overcome the cultural issues of pride and face that might have otherwise required Fujian province to decline aid. It's all about overcoming the formidable cultural barriers, and I think that that's the key.

It's the difference between your neighbor, somebody in your community coming in and offering help as opposed to a stranger from someplace you know nothing about.

When my dad first explained sister city associations right after the toxic spill four years ago, I thought he was obsessed with his involvement in both organizations. Now about to graduate from college, I plan to follow his lead and hope to work internationally for an NGO.

The Chesapeake Bay and Puget Sound are so polluted that they should be "put in the intensive care unit," according to a recent Frontline episode.

Poisoned Waters reveals that immense amounts of pollution have affected the ecosystems of both estuaries in their most basic capacities. On the surface, Puget Sound and Chesapeake Bay may look pristine and beautiful — but underneath, the effects of toxic waters are visible and disturbing.

In Chesapeake Bay, the once-thriving oyster industry has practically disappeared, although the state government recently developed a plan to revitalize the oyster population. Frontline reports that the crab industry is headed towards the same fate. David Kirwar, a Chesapeake Bay crabber, says that he only catches about half of what he did 25 years ago, describing the situation as a "tragedy." Local journalist Tom Horton said that overall "you're talking about billions of dollars of economic impact with oysters, crabs, shad, striped bass; the decline in the fisheries have just been dramatic."

Frontline says pollution caused by urban sprawl, agriculture, animal farms, and industrial sites are just some of many factors that are "slowly eating away" the bay. Jay Manning, Director of Ecology for Washington State, tells Frontline, "It's about the way we all live. And unfortunately, we are all polluters. I am; you are; all of us are."

The Mekong River. Photo: tashandsmoked(flickr)

Before it reaches the sea, the Mekong River travels more than 2,500 miles through Tibet, China, Burma, Thailand, Laos, Cambodia and Vietnam. It is estimated that more than 60 million people depend on the river in some way. But the dams are changing the river and impacting the people who depend on it.

For better or worse, four dams are already in place and 11 are on their way, most of which will be in China.

China is working to reduce their dependence on coal, and get more power from renewable sources like hydroelectricity, according to IRIN, the UN news agency, which reports that "governments downstream claim the hydroelectric dams will cut electricity costs."

The dams currently generate over 3,000 megawatts of electricity, says Radio Free Asia. A Portland General Electric representative told me that's enough electricity to power a city about the size of Portland, Oregon — with a population of 575,000 people — for an entire year.

Besides energy, the dams also help to regulate the rivers flow. As IRIN reports, supporters are saying this is a pretty impressive perk, since the region's unpredictable rains often times cause a flood or drought.

But others, including locals, don't think so highly of the dams.

According to the Foundation for Ecological Recovery, the river's fishing industry alone is worth up to $3 billion annually, and the existing dams are already decreasing that profit. Mekong fisherman Ouy Chai tells Al Jazeera that "before you could catch 10-20 fish in one day and now you can fish all week and not catch anything." His wife says, "I'm scared. What will be left for our children and grandchildren to eat?"

In the same vein, many environmentalists are saying that the dams are harsh on the environment, causing erosion and harming biodiversity. Nguyen Huu Chien, head of the environment and natural resource management program at Can Tho University, tells Radio Free Asia that "it is like a blood vessel in the human body. When we build dams, it is like a blockage in the veins: it will definitely affect other areas."

Despite the protesting and petitioning efforts of those against the dams, IRIN reports that two new ones are currently underway.
