Turtles, Arribadas, Science, Policy and Implementation

Byoliveridley

turtle Read stuff like this (hat tip to my mom for telling me about this report she’d seen on TV in Madras), and you begin to doubt your utility as a scientist.
IBNLive : Orissa turtles neck-deep in danger

Nearly 3,000 Olive Ridley turtles have died off the Orissa coast this season. Beaches have become turtle graveyards.

Orissa is one of the three places in the world where the Olive Ridleys come for their annual mass nesting.

Mechanised trawlers are the biggest culprits for this slaughter. When the trawlers go to the sea, turtles are trapped in their fishing nets. The turtles are unable to disentangle themselves and suffocate to death.

See the video report too. In her own breathlessly indignant style, the reporter explains the science behind turtle excluder devices (well known and established), the regulation expressely forbidding shrimp trawling close to the coast, especially during the arribada, the money set aside in the budget to purchase a few speed boats for the coast guard, who are well aware of the problem, so wot’s, uh, the deal?

The investigative reports contradict each other, the first one linked said there was no patrolling, the second one gushingly praises the coast guard for vigorous enforcement and patrolling, so which is it? I need to find out, call on some old friends… But clearly, there are issues if net catch mortality is on the rise.

The three pillars of any regulatory action are the science, the policy, and the implementation. The science here is very clear (though the US administration seems to not think so any more?), shrimp nets with turtle excluder devices cause decrease in mortality. The policy is clear, use these nets when shrimp fishing, and completely ban fishing activity during the arribada (the number of turtles in an arribada, 50000 in a night and perhaps 300000-400000 over the course of a week is staggeringly large, so, shrimp net or not, you’ll kill a lot of turtles just by being there).

So, like anything else in India, where is the implementation? The people running the trawlers know they are illegal anyway, so they don’t bother with the TEDs. The owners of the trawling boats never face the consequences, only the poor hapless fishermen running the boats. No attempt is made to coopt the people being regulated, it is a top down “we tell you what to do” kind of situation where the law is selectively enforced, no explanations are given, the regulation may just be an excuse to get some kickbacks. The fishermen see the excluder device as an inconvenience as they are not shown how to use it. Some low level bureaucrat in charge of buying high speed boats for the state’s forest service either does not realize the importance of getting this policy on the road, or is on the take. You can pick any, or all of these reasons and you’ll see why just like most other things in India, the road to hell is paved with good intentions 🙁

Why be a scientist and come up with cool new techniques to do things when you don’t pay equal attention to the implementation of techniques invented 20 years back? As a responsible scientist, I must look at policy and implentation with as much interest and passion as I look at the science – New career paths?

    Feds punt on Bisphenol A

    Byoliveridley

    By studiously ignoring all the subtle hormone disruption effects of bisphenol A and concentrating on easily observable neurological effects, the CERHR essentially does the industry’s bidding.

    Some risk linked to plastic chemical – Los Angeles Times

    A federal panel of scientists concluded Wednesday that an estrogen-like compound in plastic could be posing some risk to the brain development of babies and children.

    Bisphenol A, or BPA, is found in low levels in virtually every human body. A component of polycarbonate plastic, it can leach from baby bottles and other hard plastic beverage containers, food can linings and other consumer products.

    Culminating months of scientific debate, the decision by the 12 advisors of the Center for the Evaluation of Risks to Human Reproduction — part of the National Institutes of Health — is the first official, government action related to the chemical. Their recommendation will be reviewed for a federal report that could lead to regulations restricting one of the most used chemicals.

    The scientists ranked their concerns about BPA, concluding they had “some concern” about neurological and behavioral effects in fetuses, infants and children, but “minimal” or “negligible” concern about reproductive effects. The findings put the panel roughly in the middle — between the chemical industry, which has long said there is no evidence of danger to humans, and the environmental activists and scientists who say it is probably harming people.

    For a detailed look at how bisphenol research has been corrupted by industry sponsored “focused counter research” – where the goal is to show no effects and the experiment is tiled to ensure this goal, read this excellent article in the The Public Library of Science Biology Open Source Journal. Note, because it is Open Access, you can actually read it without selling a kidney! Some highlights…

    The moment we published something on bisphenol A, the chemical industry went out and hired a number of corporate laboratories to replicate our research. What was stunning about what they did,” vom Saal says with a mix of outrage and bemused disbelief, “was they hired people who had no idea how to do the work. Each of the members of these groups came to me and said, ‘We don’t know how to do this, will you teach us?’”

    More…

    The HCRA report, commissioned before Schwartz’s tenure, concluded that “the weight of the evidence for low-dose effects is very weak” [15]. Industry groups hailed the report as a comprehensive review by independent experts and quickly disseminated its findings. Yet the “comprehensive” report reviewed just 19 of 47 studies available in April 2002, and when it was published more than two years later, three panelists asked not to be listed as authors.

    What the hell, just read the whole article, especially the bit about the Harvard Center for Risk Analysis and its well documented industry shillness.

    The key to understanding bisphenol research is to realize that it is a hormone disruptor that works at low doses. At high doses, normal toxicological testing doses that is, it floods the hormone receptors and slows down the receptor pathways. So, the usual technique of testing in rats and mice at high doses and extrapolating will not work.

  • Gore speaks, you listen

    Byoliveridley

    I had a long rant brewing in my head all day about U.S intransigence at the Bali Climate talks, but hell, one massage and a Chimay later, I should just outsource to someone more qualified to lay down the law.

    AP_Nobel_Peace_Prize_winner_Al_Gore_Indonesia_eng_195.jpg

    I am going to speak an inconvenient truth. My own country, the United States, is principally responsible for obstructing progress here in Bali. We all know that. We all know that,” he said.

    VOA News – Al Gore Blames US for Climate Change Deadlock in Bali

    Here’s what pissed me off this morning…

    U.S. Strategy Succeeds in Bali
    Climate Talks Turn to Efforts Other Than Emissions Targets

    BALI, Indonesia, Dec. 13 — U.N. Secretary General Ban Ki-moon conceded Wednesday that the United States had succeeded in achieving one of its key objectives at the climate conference here, blocking a proposal that called on industrialized nations to cut their greenhouse gas emissions by 25 to 40 percent by 2020.

    Hmm, this is not even worth a rant. When the capital’s newspaper characterizes behavior that will no doubt result in untold human and material destruction as a “win”, what can be said?

  • Canada's Environmental Corpus Callosum malfunction

    Byoliveridley

    One of my first impressions on moving to Victoria was the high environmental consciousness of the people here. The obvious markers of environmental consciousness such as recycling, composting, organic food consumption, local food consumption, small car driving, and most importantly, pride at being environmentally conscious are off the charts here  (and I am  most definitely  one of those people as well!).

    My second impression was that a country with such a resource driven economy can’t possibly live up to what its citizens think it is doing. And I was right. The country as a whole performs abysmally. Canada vs. the OECD (a report produced by my very hometown University of Victoria) compares Canada’s performance vs. the OECD on a number of environmental parameters. It is shocking. The picture is painted of an inefficient economy whose consumption of major resources and pollution indicators are growing at a time they should be dropping. For example:

    Canada is among the three worst countries on nine indicators (per capita greenhouse gas emissions, sulphur dioxide emissions, carbon monoxide emissions, volatile organic compound emissions, water consumption, energy consumption, energy efficiency, volume of timber logged and generation of nuclear waste);

    Canada’s economy is inefficient, in that we use much more energy and generate much more pollution to produce a given amount of goods and services relative to our industrial competitors, including 33% more energy than the United States per unit of GDP; and

    Canada’s performance on most environmental indicators continues to worsen

    So, not only are things bad, they’re getting worse, but the people don’t seem to notice. Massive corpus callosum1 malfuction?

    BTW, this is what happens to people when their corpus callosum is removed.

    [youtube=’http://www.youtube.com/watch?v=ZMLzP1VCANo’]

    Once this theme crystallized in my head, I went searching for earlier work that would reinforce my conclusion and came upon this book Unnatural Law – Rethinking Canadian Environmental Law and Policy. From the First chapter:

    Is Canada an environmental leader or an environmental laggard? Is Canada contributing to solving environmental challenges or are we exacerbating these problems?

    Great, a book that reinforces my frame in the very first paragraph! I’ll let you know after I finish reading the book (helpfully available from my local library and written by a former ED for the SIerra Legal Defence Fund (now known as Ecojustice) and who lives on Pender Island, a few islands away from where I live! Promises to be an interesting and illuminating read.

  • Wow, Conventional Milk makes Twins!

    Byoliveridley

    44m.jpgHoly tentacular twins, Batman! This is crazy news, the first study linking the incidence of twins with environmental factors. The culprit is growth hormone fed to cows to increase milk production. According to this Wikipedia article, a third of all dairy cattle use Monsanto’s rBGH (or rBST) brand Posilac®, so obviously, use is widespread.

    FEED – July 2006 (from the Union of Concerned Scientists)

    1. Engineered hormone in milk may be linked to twinning. A recent study found that women who consumed dairy products were five times more likely to give birth to twins than vegan women. The study suggested that the use of engineered bovine growth hormone/bovine somatotropin (BGH/BST) to boost milk production in dairy cows may be related to the higher level of twinning. BGH is known to increase twinning in dairy cows. In addition, the rate of human twinning is twice as high in the United States, where BGH is used, as in Britain, where BGH is banned. BGH affects twinning rate by increasing insulin-like growth factor (IGF), a protein produced in the milk of both animals and humans, that promotes ovulation and may help early-stage embryos survive. A separate study found that levels of IGF were 13 percent lower in vegan women than in women who consumed dairy products. Read a press release about the study, which was published in The Journal of Reproductive Medicine.

    If true, no woman should ever drink “conventional” milk (non-organic, non rGBH free, etc). Twins are fun, I love my twin nieces very much, but they are much more difficult to carry and deliver, and there are more complications.

    Scary, but I suspect this is the tip of the iceberg as far as environmental effects on childbirth are concerned.

  • Carrboro Screening of "After the Peak"

    Byoliveridley

    I happened to watch an interesting short film called After the Peak about peak oil, the concept (not that revolutionary unless you ask Messrs  Exxon-Mobil, Shell and Dick Cheney!) that oil production will start declining after a certain peak production event. The docudrama made by local film maker James McQuaid was part of a public meeting on the local (Orange County, NC) responses to the coming energy crisis. Interesting conceptually, it was shown as a 30 minute local newscast, with the usual cast of characters, the too handsome eye candy anchor and his female sidekick, the young and breathless “street reporter”, the gray haired expert, and the uber-energetic sports guy! The newscast is set a year into the future when the price of gas is $10/gallon. The documentary of interviews with various community members about the effects of the price of gas on their business/life. In the 30 minutes, he touched upon food, school buses, sports, NASCAR, the poor, commutes, etc. It was an interesting effort, if a little over the top! The fake interviews with the racing track owner who’s closing his track down, the UNC athletic director who has to cancel all his long distance events, the manager of the local food store who threatens food scarcity.

    But is $10 a gallon really a big deal?

    gas-prices.png

    This simple chart shows income adjusted dollar per gallon gas prices (gas prices from 2006, income from 2004, but it should not change too much.)

    Let’s avoid the low income outliers and just compare the U.S and Germany. In April 2006, the U.S was paying $2.95 a gallon and Germany, $8.06 per gallon (ref). If you further adjust that with the per capita income of the two countries, $41,300 for the U.S versus $30,500 for Germany (ref), you will find that the price of gas in Germany is well above $10 a gallon already, they seem to be doing just fine! Maybe they just drive less. The US uses 381 million gallons of gas per day (that’s about 1.2 gallons per day per person). I agree that this comparison is a little flawed because the bulk of the German price is due to taxes, which go back to the government and are presumably used for various good deeds. Also, if the price of gas went up due to shortages, the price differential between Germany and the US would presumably stay constant (unless the Germans lowered taxes). My point is that many countries cope with high gas prices quite well, they just don’t make the same choices the Americans make, 1 acre lots, large SUVs, super long commutes, etc. There are a lot of efficiencies to be had here. The graph below shows the income adjusted gasoline price for a few countries (easy data was available!)

    My take: we need to swiftly move away from gasoline by a) Disincentivizing the use of gasoline in transportation b) Incentivizing the use of electricity for transportation. Electricity can be produced more efficiently, and pollution at the source can be controlled more effectively. A combination of a drastic increase in solar and wind power, coupled with aggressive development in battery technology should more than solve our problem without much recourse to biofuels (that great boondongle).

    Tuesdays with Turtles – Climate change and nesting patterns

    Byoliveridley

    Turns out that in Guyana, nesting patterns are changing. Different types of sea turtles are showing up, and earlier than they used to. The earlier part can be explained by climate change, but the species distribution? I am sure there are other factors involved including habitat loss, poaching, etc. Anyway, interesting story.

    Stabroek News

    The changing nesting patterns of endangered sea turtles in Guyana, is alerting environmentalists to the impact of climate change on these marine animals.

    The shell beaches in Region One have hosted thousands of nesting turtles over the years, and conservationists have been endeavouring to protect the turtles from heavy domestic use and from being traded.

    Project Coordinator of the Guyana Marine Turtle Conservation Society (GMTCS) Michelle Kalamandeen told Stabroek News recently that climate change is affecting the sea turtle population.

    According to Kalamandeen, in the 1960s the Hawksbill (critically endangered) and the Olive-Ridley (endangered) were our main nesting turtles, now the green turtles (endangered) and the leatherbacks (critically endangered) are mostly coming to nest on Guyana’s shores. The Pacific Leatherback is said to be now extinct and the Atlantic Leatherback is facing extinction.

    The change in the time period for nesting in Guyana, she said, may also be a significant sign.

    Usually sea turtles nest in Guyana from March to August every year. However, for the last three to four years, says Kalamandeen, the nesting pattern has shifted from mid-January to mid-July. This may have a significant impact on the hatchlings as food availability may be an issue for them.
