TORONTO, Feb 29 (Tierramérica) – Ecuador has taken the first step towards ending the oil dependence of its Galápagos Islands, in the eastern Pacific Ocean, with the official opening of a 10.8 million dollar wind energy facility on the island of San Cristóbal.
Ecuador’s President Rafael Correa toured the facility as part of a celebration of the 500th anniversary of the discovery of the Galápagos, and proposed to declare the islands fossil fuel free by 2015.
Located 1,000 kilometres off the coast of Ecuador, the archipelago comprises 17 small and 13 large islands that are home to 30,000 people and visited by more than 120,000 tourists each year.
Nearly everything is imported from the mainland, including vast quantities of diesel fuel for energy and transport. In 2001, a tanker ship struck a reef off the coast of San Cristóbal, one of the main islands, spilling 150,000 gallons of fuel into the ocean. Read the rest of this entry »
Feb 27 (IPS) – Free, authoritative and online: 1.8 million species.
That is the ultimate goal of the Encyclopedia of Life project, which put its first 30,000 species on the Internet this week. This ambitious global project will provide the details of every known species — habitat, range, lifecycle, pictures and more — and archive everything online so anyone can access this important information about life on Earth.
From sharks to mushrooms to bacteria, the Encyclopedia of Life will provide scientifically verified information that will satisfy both a grade school child’s curiosity or enable a university researcher — or amateur naturalist — to make a scientific breakthrough, says James Edward, new executive director of the Encyclopedia of Life (EOL) project headquartered in Washington at the Smithsonian Institution.

Feb 13 (IPS) – Malaria continues to cut a swathe through Africa, which accounts for most cases of the disease and the majority of malaria-related deaths. Globally, more than a million people die from malaria each year. In the case of children, this translates into a death every 30 seconds, according to the World Health Organisation.
A study by Burkina Faso’s Health Sciences Research Institute (Institut de recherche en sciences de la santé, IRSS) may point the way to reducing malaria’s toll on children, however.
IRSS research director Jean-Bosco Ouedraogo and his colleagues report in the current issue of ‘Nutrition Journal‘ that giving vitamin A and zinc supplements to children has been shown to reduce the incidence of malaria among them by a third. The journal is an online publication managed from London.
New ways of fighting malaria are critically needed. In recent years, the disease’s growing resistance to drugs and insecticides (malaria is transmitted by mosquitoes) has made malaria control much more challenging.
Ouedraogo spoke to IPS science correspondent Stephen Leahy.
Lots of folks have been telling me that polar bears are doing ok and don’t need protection under the US Endangered Species Act. Some say polar bear populations are stable in Alaska and increasing in parts of Canada. And there might be 1500 more bears than previous estimates according to a three year study in Nunavut which makes $2 million a year from polar bear trophy hunters. But 1500 isn’t very many more bears and with the Arctic sea ice melting fast the future certainly doesn’t look bright.
As for Alaska consider this fact:
This week scientists announced new findings that the survival rate of polar bear cubs in Alaska’s Beaufort Sea has plummeted. In the late 1980s, 65 percent of polar bear cubs in the southern Beaufort Sea survived their first year. That has fallen to an average of 43 percent in the past five years. — Polar Bears Go Hungry as Icy Habitat Melts Away
“Without taking serious and urgent action to stabilize the climate, there is no future for polar bears” says Andrew Derocher, Chair of the World Conservation Union (IUCN), Polar Bear Specialist Group.

Feb 15 (IPS) – Oceans span nearly three quarters of the Earth’s surface and despite this vast size hardly a square kilometre has been untouched by humans.
Researchers released the first-ever global map of human impacts on oceans Thursday in the journal Science. Impacts ranged from fishing to pollution to ship transportation.
“There really aren’t any areas without human impacts,” said Kimberly Selkoe, a principal investigator on the project and a post-doctoral researcher at the University of Hawaii.
“The most shocking message here is that we don’t actually have a lot of data on human impacts,” Selkoe told IPS. Read the rest of this entry »
Last summer while working in the Galapagos Islands I wrote about Planktos, a company that wanted to create plankton blooms near the islands by dumping tons of iron particles into the ocean: Carbon Project Endangers the Galápagos.
Planktos hoped these plankton blooms would ultimately become a lucrative way of removing carbon from the atmosphere. However in a January issue of the journal Science, a number of international scientists issued a warning that not enough was known to commercialize what is known as iron fertilization of the oceans.
Last summer’s dumping in the Galapagos never went forward, in part because of strong local objections, concern by marine scientists over unintended impacts and international environmental group protests. Feb 13 Planktos announced indefinite postponement of the experiment due to lack of investment funds because of “an effective disinformation campaign” by those opposing the effort.
Under the North American Free Trade Agreement (NAFTA), Canada lost control over its energy resources. Now, with “NAFTA-plus”, Canada could also lose control over its freshwater resources, say experts in this Sept 2007 article CANADA: Losing Control of Water Through NAFTA and SPP
Now the Canadian Water Issues Council (CWIC) has written a model law to protect Canadian waters.
“There is a growing risk that North Americans may commit the ultimate ecological error by beginning to move large amounts of water over long distances, resulting in massive economic losses and ecosystem collapse in many donor regions,” says Ralph Pentland, CWIC’s Acting Chairman.
“The model legislation, drafted by the Council, addresses the need for a national approach to protecting this vital resource.”
See webcast of panel discussion on this and what it may take to turn this into real law.
UK-based jurno Gwynne Dyer suggests it is time to panic over climate change and cites plenty of evidence (nearly all of which you can find on this site) including southern Africa losing 30 per cent of its corn crop as climate gets hotter and drier there.
Dyer goes on to say:
The two Democratic candidates for the presidency in the United States promise 80 per cent cuts in emissions by 2050, and John McCain for the Republicans promises 50 per cent cuts by then.
Nobody points out such a leisurely approach condemns the world to a global temperature regime at least three or four degrees Celsius (5.5 to 7 degrees Fahrenheit) warmer than today.
Nobody points out those are average global temperatures which take into account the relatively cool air over the oceans. Read the rest of this entry »

Feb 8 (IPS) – Biofuels are making climate change worse, not better, according to two new studies which found that total greenhouse gas emissions from biofuels are far higher than those from burning gasoline because biofuel production is pushing up food prices and resulting in deforestation and loss of grasslands.
“Emissions from ethanol are 93 percent higher than gasoline,” said David Tilman, an ecologist at the University of Minnesota and co-author of one of the papers published Thursday in the journal Science.
“The bottom line is that using good farmland for biofuels increases greenhouse emissions,” he said.

Feb 4 (IPS) – Biofuels have quickly turned from environmental saviour to just another mega-scale get-rich quick scheme. Countries and regions without their own oil reserves to tap now see their farms, peatlands and forests as potential “oil fields” — shallow but renewable lakes of green oil.
Renewable does not mean sustainable, and in most cases the only green part of biofuel is the wealth they generate.
Not surprisingly, given the record high oil prices, worldwide investment in bioenergy reached 21 billion dollars in 2007, according to the U.N. Environment Programme. The Inter-American Development Bank announced 3 billion dollars for investment in private sector biofuel projects — mainly in Brazil — while the World Bank said it had 10 billion dollars available in 2007.
Meanwhile development assistance for food-producing agriculture had fallen to 3.4 billion dollars in 2004 — with the World Bank’s share less than 1 billion dollars, according to the Bank’s own World Development Report on Agriculture released in October 2007. And most of this financial assistance was spent on subsidising use of chemical fertilisers. Read the rest of this entry »
