Kenyan Birds and Sugar Cane

A flourishing wetland on Kenya’s northern coast is under serious threat from plans to grow vast amounts of sugarcane, partly for biofuel production. Developers want to transform nearly 20,000 hectares of the spectacular Tana River Delta, into sugarcane plantations with other parts of the Delta earmarked for rice.”This development would be a national disaster, wreaking havoc with the area’s ecosystem and spelling the end for wildlife across much of the Delta”, said Paul Matiku, Executive Director of NatureKenya. “Large areas would become ecological deserts. The Delta is a wildlife refuge with cattle herders depending on it for centuries as well. There is no commitment to mitigation for the damage that will be done and no evidence that local incomes will be in any way improved. The sugarcane scheme cannot be allowed to go ahead.”The Delta, covering 130,000 hectares in total, is one of Kenya’s largest and most important freshwater wetlands. It is a vast patchwork of habitats including savannah, forests, beaches, lakes, mangrove swamps and the Tana River itself. Local people live by the seasons, adapting to the regular floods that keep the area fertile through the year.The sugarcane scheme, submitted by Mumias Sugar Company and Tana and Athi River Development Authority, proposes nearly 50,000 acres of irrigated sugarcane, together with sugar and ethanol plants. Local community livelihoods are likely to be severely impacted by any large-scale irrigation project.

An Ocean of Despair

Almost half of the world’s oceans have been ruined to some degree … often very severely … by human activity. You’ve heard a lot on the news and in the blogosphere about this lately. This increased interest is in part because of the recent production (Feb 15th Science) of a map of the ocean showing these impact.Here is the map:i-1ad466ce88f4a52acfcaf1b830db6cc8-ocean_map_small.jpgClick Here to View Larger Image Continue reading An Ocean of Despair

New Zealand announces measures for albatross

BirdLife International has welcomed the measures announced by New Zealand Fisheries Minister Jim Anderton to reduce the number of seabirds killed in New Zealand’s fisheries. This follows an incident last year where a single longline vessel fishing in the Chatham Rise area of New Zealand was responsible for the deaths of 36 albatrosses including 12 Critically Endangered Chatham Albatross Thalassarche eremita.”We are delighted that New Zealand is bringing its fishing practice into line with internationally recognised best practice. The New Zealand Minister of Fisheries should be congratulated on his decision”, said John Croxall, Chairman of BirdLife’s Seabird Programme.

Are We In The Anthropocene? No.

ResearchBlogging.orgProposals to give the latter part of the present geological period (the Holocene) a new name … the Anthropocene … are misguided, scientifically invalid, and obnoxious. However, there is a use for a term that is closely related to “Anthropocene” and I propose that we adopt that term instead. Continue reading Are We In The Anthropocene? No.

Did Humans or Climate Change Cause the Extinctions of Pleistocene Eurasian Megafauna?

Blogging on Peer-Reviewed ResearchDid humans wipe out the Pleistocene megafauna? This is a question that can be asked separately for each area of the world colonized by Homo sapiens. It is also a question that engenders sometimes heated debate. A new paper coming out in the Journal of Human Evolution concludes that many Pleistocene megafauna managed to go extinct by themselves, but that humans were not entirely uninvolved.

New Study of Antarctic Ice Loss

Blogging on Peer-Reviewed ResearchThe amount of ice lost to the sea from Antarctica has increased by 75 percent in the last 10 years. This is the result of an increase in glacial flow. It had previously been thought, and perhas was the case, that Greenland ice loss outpaced the Antarctica. This is no longer the case. Continue reading New Study of Antarctic Ice Loss

Critical duck bouncing back

A translocated population of the Critically Endangered Laysan Duck has reached 200 in only three years.
Anas laysanensis is commonly known as the Laysan Duck. It occurs in the Papahanaumokuakea Marine National Monument, and nowhere else, though it was once found across the Hawaiian Island chain. They were nearly wiped out by 1860, confined thereafter only to Laysan Island. Continue reading Critical duck bouncing back

The Evolution of the Modern Climate: New Evidence from Plant Remains

Blogging on Peer-Reviewed ResearchThings are just not like what they used to be. You know this. You know that the Age of Dinosaurs, for instance, was full of dinosaurs and stuff, and before transitional fossil forms crawled out of the sea to colonize the land, all animals were aquatic, etc. But did you know that from a purely modern perspective, the Miocene was the most important geological period?

Geek the Vote

Popular Mechanics (one of those magazines that genteel people refuse to admit they read, but that is actually a blast) has published a thing called “Geek the Vote.” According to an email from PM, this is:

…an online guide to all the candidates’ stances on issues related to science and technology including energy policy and climate change, gun control, science education and infrastructure investment. The full chart, which can be navigated by candidate or issue, is [provided]

The site is here.This is apparently in response to (maybe not, but there is evidence to suggest this) the Science Debate 2008 initiative (see this). Continue reading Geek the Vote

Bali: Are we there yet?

The Cost of twenty years of Reagan and Bushes has been very high. In about 1991, I wrote an article for a monthly newspaper in which I summarized the available data for Global Warming, and was very easily able to conclude that it was a real phenomenon with consequences already felt in a number of areas, a reasonably well understood mechanism, and a tangible set of solutions to work on. In 1997, the Kyoto protocol was signed on to by a number of nations (the US not included because of congressional Republican opposition). This month, in Bali, a re-run of something like Kyoto happened, and finally, the US is also signed on with most of the rest of the world.
