Swedish Entrepreneur Dreams Up Disposable Toilet

According to the United Nations, an estimated 40 percent of the global population, or close to 2.6 billion million people do not have access to a toilet of any sort, even a pit latrine.

This has created a public health crisis in developing countries, both in terms of contaminated drinking water and poor sanitation techniques. More than one million children mostly under the age of five die each year from diarrhea resulting from this lack of sanitary conditions. While the technology exists to solve this problem, it is expensive and sometimes hard to install.

But Swedish architect and entrepreneur, Anders Wilhelmson is hoping to tackle the issue with his invention: a safe, affordable, biodegradable plastic bag called the Peepoo that can be used as a single-use toilet.

World’s Pall of Black Carbon Can Be Eased With New Stoves

written by Yale Environment 360

Two billion people worldwide do their cooking on open fires, producing sooty pollution that shortens millions of lives and exacerbates global warming. If widely adopted, a new generation of inexpensive, durable cook stoves could go a long way toward alleviating this problem.

With a single, concerted initiative, says Lakshman Guruswami, the world could save millions of people in poor nations from respiratory ailments and early death, while dealing a big blow to global warming — and all at a surprisingly small cost.

“If we could supply cheap, clean-burning cook stoves to the large portion of the world that burns biomass,” says Guruswami, a Sri Lankan-born professor of international law at the University of Colorado, “we could address a significant international public health problem, and at the same stroke cut a major source of warming.”

Sooty, indoor air pollution from open wood or other biomass fires has long been linked to health problems and deaths. More recently, scientists have been surprised to learn that black carbon — not only from biomass fires but from dirty diesel engines and other sources — is a far larger contributor to global warming than previously suspected: The dark particles absorb and retain heat close to the Earth’s surface that might otherwise be reflected.

Global Water Crisis: You’d Think Water Would Be a Basic Right

written by Peter Asmus

In the slums of Kibera in Nairobi, Kenya, about 1 million poor people pay up to 30 times more for water of dubious quality brought to them in old tanker trucks than middle-class citizens pay for clean and safe water provided by the local public water utility via standard household connections.

Some may be shocked by these disturbing disparities in the developing world, but a lack of access to safe, affordable and clean water is also an issue in California, particularly in the Central Valley and along the Central Coast. In these communities, more than 90 percent of drinking water is sucked from contaminated groundwater sources. All told, more than 150,000 California residents lack safe water for drinking, bathing and washing dishes; even more have water service disconnected because they cannot afford to pay their bill.

Universities Partner on Water Purification Research

written by Jonathan Shapira

Ben-Gurion University of the Negev has partnered with the University of Johannesburg and the University of California, Los Angeles to conduct scientific research into the fields of water purification and microalgal biotechnology, according to a press release last month.

“This is an international partnership that will benefit the peoples of South Africa, Israel and other countries around the world,” said BGU’s Vice President for External Affairs Prof. Amos Drory on occasion of the signing. Drory and Prof. Derek van der Merwe, Pro Vice-Chancellor at the University of Johannesburg, signed the research collaboration agreement in South Africa.

“The two universities will become involved in extremely important, evolutionary research that will mainly benefit third world countries throughout the world,” said Dr. Bertram Lubner, Vice-Chairman of BGU’s Board of Governors and president of the SA Associates of Ben-Gurion University (SAABGU).

Prof. Sammy Boussiba and Prof. Yoram Oren from Ben Gurion University’s Blaustein Institute for Desert Research will head up the projects in Israel working together with Prof. Bhekie Mamba, leading the South African research teams. They will be assisted by Prof. Eric Hoek, an expert in the fields of water purification and microalgal biotechnology at UCLA.

India Makes Dramatic Emissions Policy Shift

written by Elsa Wenzel

Article by Mridul Chadha appearing courtesy of Celsias.

In yet more positive news for international climate negotiations, India has announced that it is open to international review and reporting of its domestic mitigation measures.

The step is a colossal change in India’s policy and is seen as a major boost to the chances of successful negotiation of new climate deal at Copenhagen this December.

India has long maintained that it is bound to report results of only internationally funded clean energy projects. The issue of reporting and accounting of carbon emission reduced has been a contentious issue for a long time.

Over-Consumption Causes More Emissions Than Population Growth?

written by Elsa Wenzel

Rapid population growth in the developing world does not significantly contribute to rising greenhouse gas emissions and focusing on the population explosion in poor countries diverts attention from the far more serious issue of over-consumption in rich countries, according to a new study.

The study, conducted by the International Institute for Environment and Development, analyzed population growth and CO2 emissions from 1980 to 2005 and concluded that rising populations in sub-Saharan Africa and other poor regions have had a negligible impact on global warming.

Developing World Fights Pollution & Traffic With Low-Emission Buses

written by Ceylan Thomson

Large, low-emission buses being introduced in developing cities from Mexico City to Ahmedabad, India are reducing congestion on crowded roadways and cutting pollution and carbon dioxide emissions, all at a much lower cost than constructing subways.

In Bogota, Colombia, city leaders took control of two to four center lanes of major boulevards for the TransMilenio rapid transit system. Small walls isolate the “tracks” of the bus lines from other traffic, and passengers are able to board the long, segmented buses from the center platforms of modern stations.

Sustainable Energy in the Developing World

written by Bryan Hassin

Back in June I was in Kenya to learn about the business challenges they faced there–especially after all the post-election violence. It was a very eye-opening trip in many ways; I had the opportunity to meet everyone from the most notable dignitaries and business leaders to the poorest slum residents. Each of the meetings was very interesting, although I didn’t find the one with the executive director of Climate Network Africa to be very productive. She was full of climate change blame for the US/Europe, didn’t offer any constructive solutions, and demanded reparations for the damage that would surely come to the African environment. I found this unproductive for several reasons.

First, her supporting data were misleading. She drew facts and figures from several years ago, when the US and Europe were way ahead of everyone in carbon emissions. Don’t get me wrong; the US and Europe are still way ahead, but the gap is closing a little and the trends, which show developing nations like China overtaking them in the future, reveal that the problem must be addressed globally, not just in a few countries. She also used exclusively per capita carbon emissions statistics, which are irrelevant. The environment doesn’t care how many people are producing the emissions; it just cares that they are being produced! By her logic, the US could become a better global citizen just by increasing its fertility rate instead of reducing its emissions!

Second, she was all problem and no solution. Yes, we all know that the industrialized countries have been the greatest emitters, but it is unproductive to rehash this over and over and over again. Yes, we screwed up. No, we didn’t know the consequences industrialization would have until relatively recently but yes, we accept responsibility for it. Now let’s stop playing the blame game and all work together to find a solution!

Finally, her antagonistic “The West is evil” presentation isn’t likely to motivate any action. A large organization exhibits a collective subconscious that behaves in a very irrational, human way. Attacking developed countries is likely to induce defensiveness, not action. A collaborative approach would be much more constructive.
