Insecticides such as DDT have long been used to combat the scourge of malaria in the developing world. But with the disease parasite becoming increasingly adept at resisting the chemical onslaught, some countries are achieving striking success by eliminating the environmental conditions that give rise to malarial mosquitoes.

For over half a century, the battle against malaria has been waged with powerful anti-malarial drugs and potent mosquito-killing insecticides, weapons born from the wonders of synthetic chemistry. In recent years, however, fed up with the financial and ecological drawbacks of chemical warfare, malarious communities from China to Tanzania to Mexico have been forging a new way to fight the scourge, one that draws inspiration from the lessons of ecology more than chemistry. Rather than attempt to destroy mosquitoes and parasites outright, these new methods call for subtle manipulations of human habitats and the draining of local water bodies — from puddles to irrigation canals — where malarial mosquitoes hatch.

The most striking example comes from Mexico, which has completely abandoned its previously lavish use of DDT in malaria control for insecticide-free methods and has seen malaria cases plummet.

Like many countries, Mexico for decades relied upon insecticides to fight the disease, by spraying mosquito-killing chemicals on the interior walls of homes where blood-feeding mosquitoes rest, among other methods. Between 1957 and 1999, taming Mexico’s malaria required 70,000 tons of DDT. (more…)

In Normandy, France, a company makes a nutritional supplement called Plumpynut that offers the best hope for the world’s starving children.

Invented in 1999 by French pediatric nutritional scientist Andre Briend, who is affiliated with the World Health Organization (WHO), and manufactured under the flagship French company Nutriset, which was formed in 1986 to address the nutritional problems of populations at risk, the product is manufactured under license from the company in several African countries where, in the past five years, it has transformed the treatment of malnourished children.

According to Doctors Without Borders’ chief nutritionist, Dr. Milton Tectonidis, the product is remarkable in that it delivers a mega-burst of essential nutrients like protein, calcium, vitamins and minerals from a sterile, single-serving packet that doesn’t require any refrigeration, cooking, or clean water.

Twenty-six projects have won funding of up to $200,000 each to develop their concepts in the 2009 IDEAS Energy Challenge. Jointly sponsored by Global Village Energy Partnership International, GTZ, IDB and the Government of Korea, the competition supports project ideas which demonstrate an innovative response to tackling the energy challenges facing Latin America and the Caribbean today.

GVEP International highlights three cases where the scheme is expected to facilitate considerable growth in the renewable energy framework of impoverished regions of Central America.

Amid the valleys, mountains and volcanoes of the highlands of southern Guatemala lies one of the country’s largest lakes, Lake Amatitlan. Located just 16 kilometers south of Guatemala City, the unique landscape surrounding the lake means it is used by many people as a recreation area.

A group of Colombian farmers has filed a lawsuit against the oil company BP, claiming that construction of a 450-mile pipeline in the mid-1990s has caused landslides, permanently damaging soil and crops and harming livestock.

In the suit filed in a London court, 95 farmers claim that BP Exploration Company ignored evidence that the pipeline would damage the land, and never informed the property owners, many of them illiterate, of the risks.

The pipeline, which delivers as much as 620,000 barrels of crude oil to an export terminal daily, crosses 192 rural villages. Farmers say that during construction, natural vegetation that protected their soil from the elements was removed, leading to significant erosion. (more…)

The developing world, where 44 percent of people lack access to electricity, could soon be one of the biggest markets for solar power, according to participants at the Solar Power International conference in California.

To date, just 1 percent of solar panel production has been installed in poor nations in Africa, Asia, and Latin America, a situation that Michael Eckhart, president of the American Council on Renewable Energy, called “a scandal for our industry.”

For thousands of years, the native Aymara people have been harvesting scarcely fallen raindrops along the Andean foothills in northern Chile by capturing the rainwater in nets for irrigation and drinking purposes. The people in this region, in and around the Atacama desert, are accustomed to fragile ecosystems and an extremely dry climate. However, today, even in the fertile central and southern regions of Chile, there are noticeable tensions over water rights and water availability.

Presently, it is not as if there are times when nothing flows out of the tap here. Nor are the urban folks of Santiago running outside their homes with their own polypropylene mesh nets ready to catch any drop of rain that falls. However, a convergence of factors – an increase in population growth, perceptible changes in climate patterns, and competition for water resources between various industries and hydro power – have caused a national “war over water” of sorts to emerge at the forefront of national environmental, economic, and political discussions.

“No doubts remain. Climate change is real and the build-up of greenhouse gases in our atmosphere is increasingly at an alarming rate.” With these words, Rafael Quiroga, General Manager of Accion RSE, initiated the seminar “Corporate Strategic Management of Climate Change and Greenhouse Gas (GHG) Emissions.” This is not another “green business” seminar from a European or North American city, it took place here — in Santiago, Chile.

The event brought together speakers from the Chilean private sector that gave concrete examples of their companies’ climate change and GHG management initiatives. First, it showed how Essbio, a water purification company, has been dealing with the ever-prescient and escalating challenges of decreasing water reserves due to climate change.  Second, it illustrated the emissions and energy reductions Xstrata Copper, a mining company, has committed to and the steps it has taken to minimize the release of contaminants in its industrial processes. Third, it explained what Natura cosmetics has done since 2007 to become a “carbon neutral” business by calculating all GHG emissions in the company’s supply chain, transportation, and production of its various cosmetics products, and purchasing the equivalent amount of CO2 tonnage in carbon credits on the international carbon markets.

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.

I spent the last couple days learning about how countries in Latin America, Africa and the Caribbean might best to stimulate the implementation of renewables at the first annual REEM Conference. The conference was largely an attempt to identify and some lessons learned and best practices from the EU, and even the US, which could help shape policy in these regions.

I would contend that knowledge sharing is always constructive. Yet, as some of the entrepreneurs on the panel explained their decidedly unique and varied frustrations and successes surrounding each of their projects, I could not help but feel that the concept of pontificating on would be effective policies for a developing countries from a well lit and air conditioned downtown San Francisco hotel ball room was a bit cheeky, if not resoundingly inadvisable.

Chile is essentially a very long coast, with mountains in the back with nice people between the two that have set up the most stable state in Latin America. A great environment to install wind turbines. If you add to that the presence of enough local skilled workers, with a good safety culture – essential in the industry – that comes from the mining sector, and a good grid, then you would for sure assume that there are already plenty of wind farms up and running.

Well no. As of last December, only one was operational: a mere 18 MW owned by Endesa (of all utilities). The main reason of this seems to be the lack of a wind cartography.
