Pesticide Exposure and India's green revolution

Pesticide exposure in Punjab and Haryana is out of control. When I was growing up, the Green Revolution was idolized and idealized to degree that in hindsight seems a little excessive. But back then, this octupling of wheat and rice yields in Punjab and Haryana catalyzed the transformation of India from a country mired in famine and food shortages to one that occasionally runs out of room to store excess food. So, this story (courtesy of 3QD) caught my attention.

Green.view | Chemical generation | Economist.com:

IF INDIAN newspaper reports are to be believed, the children of Punjab are in the throes of a grey revolution. Even those as young as ten are sprouting tufts of white and grey hair. Some are going blind. In Punjabi villages, children and adults rare afflicted by uncommon cancers.

The reason is massive and unregulated use of pesticides and other agricultural chemicals in India’s most intensively farmed state. According to an environmental report by Punjab’s government, the modest-sized state accounts for 17% of India’s total pesticide use. The state’s water, people, animals, milk and agricultural produce are all poisoned with the stuff.

Ignorance is part of the problem. The report includes details of a survey suggesting that nearly one-third of Punjabi farmers were unaware that pesticides come with instructions for use. Half of the farmers ignored these instructions. Three-quarters put empty pesticide containers to domestic uses.

The article concludes by saying that the government is encouraging the use of techniques including organic farming, more crop rotation, etc, and how this is ironically “reversing” the green revolution. But two separate issues are getting mixed up here. The green revolution was not won on excessive use of fertilizers, monoculture, excessive water use, and so on. Instead, the development of new hybrid, high yielding varieties of rice and wheat kick started the revolution. The wholesale adoption of water and input intensive agricultural techniques came along for for the ride with the rest of the revolution.

Hopefully, the Punjab government will not stop at writing reports, but start grassroots education projects with the farmers to encourage sensible farming techniques that take the good parts of the green revolution and leave the bad parts out.

    South Asians: Watch your Heart

    Seems like us South Asians die earlier from heart attacks.

    ScienceDaily: South Asians Have Higher Levels Of Heart Attack Risk Factors At Younger Ages

    Deaths related to cardiovascular disease occur 5 to 10 years earlier in South Asian countries than in Western countries, according to background information in the article. This has raised the possibility that South Asians exhibit a special susceptibility for acute myocardial infarction (AMI; heart attack) that is not explained by traditional risk factors.

    But why?

    The prevalence of protective risk factors (leisure time physical activity, regular alcohol intake, and daily intake of fruits and vegetables) were markedly lower in South Asian study participants compared with those from other countries.

    Um, it is mainly behavioral, not genetic according to the authors, and hence can be mitigated by lifestyle changes.

    Well, I guess it is time to take a personal stock as of 1-18-2007:

    • Weight – Well, I am in the lower end of the healthy BMI.
    • Exercise – 4-5 days of 45 minutes – 1 hour per day, pretty good.
    • Food – Well, mostly good, especially if the candy can be avoided. I need to eat more vegetables, but I eat a lot of high fibre, and whole wheat food, probably not enough protein, mostly vegetarian.
    • Alcohol (1-2 drinks is apparently a heart protector) – Amen, I am a religious one drink a day partaker, more on weekends :-;
    • Smoking – Well, gave that up a while back, now to quit that occasional “party” smoke.
    • Stress – Well, not so good, this is probably the area I would need to work on the most.
    • Hypertension – Well, I am borderline on my blood pressure readings 🙁 Need to work on that.
    • Cholesterol – Still waiting for results on my physical.

    On the whole, I seem to be in decent shape. It’s good to take stock once in a while.

  • Doom and Gloom on Canadian Climate Change Report

    “The conclusions [the report] draws are irresponsible,” said Mr. Prentice in an interview with The Globe and Mail from Kingston, where he was meeting with provincial and territorial environment ministers. Specifically, he said Canadians will not accept the report’s advocacy of emission targets for 2020 that would reduce Canada’s gross domestic product by 3 per cent nationally and 12 per cent in Alberta from business-as-usual estimates.

    Climate change report ‘irresponsible,’ Prentice says – The Globe and Mail.

    Canada cannot take its national unity for granted and must not, in the service of international obligations, allow itself to be immolated by a government policy of such wrenching dislocation.

    Globe and Mail Editorial

    Wow, “irresponsible”, “Threat to Canada’s National Unity?” What could we talking about? Surely, not a report that addresses the cost of meeting Canada’s commitments to greenhouse gas reductions by 2020?. A bit of hyperbole from this nation’s great flagship newspaper and the Environment Minister?

    The study (English summary) looked at two different scenarios, first the weak sauce 20% reduction from 2006 levels by 2020 proposed by the Canadian government. The reason the Canadian government deliberately shifted the baseline from 1990 (the accepted consensus baseline so comparison can be made easily) to 2006 is that if you calculate what the change from 1990 levels is for the Canadian government proposal, it is actually a small increase, not the 20-25% decrease that is needed to put the world on a stabilization path for <2°C rise in temperature. This is unethical and dishonest, like telling the world that the average Canadian is 4 feet tall (head to knee only). The authors of the report know this is an unacceptably weak proposal and therefore looked at what was actually needed, a 20-25% reduction from 1990 levels. BTW, remember that if someone ever shoots a percentage off for you, ask for the baseline, check if this is standard.

    Incidentally, the editorial pages of the G&M has not read its own report, or wilfully ignores all the good news while selectively playing up the bad news, geez, it’s like they have an agenda or something! The good news:

    • Canada CAN meet its climate goals
    • The effect on Canadian GDP growth is modest. Under the required goal of 25% reduction from 1990, GDP growth is about 3% below “business as usual” standards. Note that this year, GDP growth was negative, what percent is that?
    • Alberta, which would “suffer” the greatest reduction from “business as usual” scenarios still leads the country in growth. This is the scenario which the G&M concern trolls as a threat to National Unity
    • Jobs still grow, very few changes from business as usual scenarios
    • Significant Increases in energy costs. But money flows from carbon revenue to defray some of these costs, so actual costs to consumers are modest
    • Massive increases in the efficiency of cars, houses, heating, etc., means lower prices in the long run

    Of course, the environmental, social and geopolitical costs of “doing nothing” are not enumerated. Are we prepared to face a world with melting polar ice caps, climate refugees, water wars and anger? Are we willing to take those Canadian flags off our backpacks and put Swedish flags on them? There is also a very good chance of incremental breakthroughs in electric vehicle technologies squeezing the demand out of oil and completely collapsing Alberta’s economy, making this entire decision moot. Things can change quickly, just ask anyone involved in the BC timber industry! My point is that unless you factor in the costs of doing business as usual, any change proposed will not compare favourably. The report alludes to the cost of doing business as usual, a 5-20% LOSS in global GDP over the century. But does not include this into the calculation of the business as usual scenario. Note that none of the changes envisaged here propose anything but “growth”.

    The changes required are quite significant.

    • Capture and storage of carbon dioxide from the oil and gas industry and power plants (Ha!)
    • Reduction of “fugitive” emissions from the oil and gas industry and from landfills
    • Increased energy efficiency throughout the economy (e.g., in vehicles and buildings)
    • Increased production of renewable energy (e.g., wind power accounts for 18 per cent of electricity generated in 2020 when meeting the 2°C target)
    • Replacement of fossil fuels by cleaner electricity (e.g., for heating buildings).

    When you are near the bottom of the pack when it comes to efficiency and per capita emissions, you do necessarily have to work a little harder. Most of these goals (except the first one which needs a major technological advance) are easily achievable and would put Canada more in line with European countries as far as energy efficiency goes.

    What do the words of the mainstream media and the government mean? We are screwed. Canada has NO leadership or commitment to steer away from the cliff. We do not have a powerful enough constituency for climate change. We have a government and polity completely captured by oil interests. We will be dragged kicking, screaming and unprepared into a new, efficient and carbon constrained world. We may still turn out okay because we are a VERY rich country with very few people. But, be prepared for the backlash.

    Note, more from the excellent blog greenpolicyprof ‘which makes some of the same points I made, but expands to include coverage of West vs. the Rest issues.

  • Obama seeks U.S. carbon emissions cap

    President Barack Obama on Tuesday called on Congress to send him legislation that places a market-based cap on U.S. carbon polluting emissions and pushes the production of more renewable energy.

    In his first speech to a joint session of Congress, Obama said that “to truly transform our economy, protect our security, and save our planet from the ravages of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy.

    Good, Canada will have to harmonize. Stephen Harper was last seen pretending that his “intensity based”” approach was just a “different” way of measuring emissions. You can say that speed and distance are just two ways of measuring travel!

    It is still early and we will see what the US congress can come up with, and what egregious exemptions and offsets it will provide for. Lobbying is already fast and furious. But the news emanating from Obama is promising on the climate change front.

    Lead and Crime

    leadcrime.jpg

    The next time Giuliani tries to take credit for the decrease in violence during his tenure as NYC’s mayor, send him this chart.

    The NY Times shines some light on Jessica Reyes’ excellent work linking decreased lead exposure to a drop in violent crime in the US. The decreased lead exposure, of course, was from the phase-out of leaded gasoline from the American market. BTW, Nascar still uses leaded gasoline in its cars, nice going, guys.

    The answer, according to Jessica Wolpaw Reyes, an economist at Amherst College, lies in the cleanup of a toxic chemical that affected nearly everyone in the United States for most of the last century. After moving out of an old townhouse in Boston when her first child was born in 2000, Reyes started looking into the effects of lead poisoning. She learned that even low levels of lead can cause brain damage that makes children less intelligent and, in some cases, more impulsive and aggressive (Emphasis Added).

    Lead exposure at an early age (2-3 years) is especially significant as this is an age where personality development occurs and any interference in neuron development and apoptosis (death!) can cause permanent changes in personality. This excellent review article summarizes the effects of lead on neuronal development.

    Reyes’ research mentions that while decreased lead exposure was very well correlated with violent crime (accounting for 56% of the reduction in crime), no correlation was found to property crimes (such as theft). This of course makes intuitive sense. A property crime is usually premeditated whereas violence is usually impulsive (excluding serial killers, of course). It is more likely that a budding criminal sets out to steal a car than to beat somebody to pulp. It is when the crime goes wrong that the probability of a violent crime increases. An individual with damaged impulse control is then more likely to seek a violent way out of the bad situation.

    Our society (like most) views violent crime as a moral issue, a matter of good and evil that is determined by your “character”. So, a simple chemical correlator to violent crime that can explain a majority of the commission of violent acts goes a long way in undermining this whole notion of morality and crime. Of course, there are other sociological factors at play which need to be addressed. But it is heartening to know that beyond all the complicated and recalcitrant social issues that underly crime, there’s a ubiquitously evil pollutant lurking that can be eliminated. I am guessing that this line of reasoning is not going to be very popular among the “tough on crime” types that perpetrate our political airwaves these days.

  • Tariq Ali: Has the U.S. Invasion of Pakistan Begun?

    The decision to make public a presidential order of last July authorizing American strikes inside Pakistan without seeking the approval of the Pakistani government ends a long debate within, and on the periphery of, the Bush administration. Senator Barack Obama, aware of this ongoing debate during his own long battle with Hillary Clinton, tried to outflank her by supporting a policy of U.S. strikes into Pakistan. Senator John McCain and Vice Presidential candidate Sarah Palin have now echoed this view and so it has become, by consensus, official U.S. policy.Its effects on Pakistan could be catastrophic, creating a severe crisis within the army and in the country at large. The overwhelming majority of Pakistanis are opposed to the U.S. presence in the region, viewing it as the most serious threat to peace.

    Tomgram: Tariq Ali, Has the U.S. Invasion of Pakistan Begun?

    This part of the world could see even more escalation in violence and death. Imagine the terror in the population as unmanned drones routinely fly over and drop bombs from the sky. The US government created this problem in the 1980s when fighting its proxy cold war. It decided that communism was a big enough threat to justify the arming of religious fundamentalists. We still continue to pay the price.

    When will this colonialist meddling end? If the last 100+ years have shown us anything, Western forces cannot control this region by force, yet they keep trying, keep killing people and keep the flames alive.

    Unfortunately, the women and children of this area just don’t have good alternatives. They either get oppressed by their moronic fundamentalist men or get western bombs hurled from the sky at them. Would 20 years of peace, under even fundamentalist conditions, provide enough stability to make incremental change possible? I don’t know, but I do know that unmanned “drones” dropping bombs from the sky will not bring peace.

  • Apparently, the Earth is warming up…

    story.global.warming.2.jpgAnd Dog bites man, yet again, it’s amazing how they keep doing that. Think of all the money being wasted on re-proving the obvious, this is money not spent in mitigating the effects, money not spent on research, money not spent on encouraging people to use more efficient lighting… It’s a shame.

    CNN.com – Study: Earth ‘likely’ hottest in 2,000 years – Jun 22, 2006

    Climate scientists Michael Mann, Raymond Bradley and Malcolm Hughes had concluded the Northern Hemisphere was the warmest it has been in 2,000 years. Their research was known as the “hockey-stick” graphic because it compared the sharp curve of the hockey blade to the recent uptick in temperatures and the stick’s long shaft to centuries of previous climate stability.

    The National Academy scientists concluded that the Mann-Bradley-Hughes research from the late 1990s was “likely” to be true, said John “Mike” Wallace, an atmospheric sciences professor at the University of Washington and a panel member. The conclusions from the ’90s research “are very close to being right” and are supported by even more recent data, Wallace said.

    The panel looked at how other scientists reconstructed the Earth’s temperatures going back thousands of years, before there was data from modern scientific instruments.

    For all but the most recent 150 years, the academy scientists relied on “proxy” evidence from tree rings, corals, glaciers and ice cores, cave deposits, ocean and lake sediments, boreholes and other sources. They also examined indirect records such as paintings of glaciers in the Alps.

    Combining that information gave the panel “a high level of confidence that the last few decades of the 20th century were warmer than any comparable period in the last 400 years,” the academy said.
