Why land use is critically important for climate change

Byoliveridley

That’s the argument from a new paper published in Science today, written by Princeton University’s Tim Searchinger and others. The upshot? Clearing out forests to use the wood for bioenergy clearly has an environmental cost, but that’s simply not accounted for in any of the prevailing climate-change programs. Kyoto, the European cap-and-trade plan, and the House climate bill all treat bioenergy as carbon-neutral; nobody counts the effect of disappearing forests.

In my long blog post earlier this morning, I briefly alluded to the fact that proposed Canadian climate change legislation explicitly excludes land use. Well, bad idea! I am surprised this is being trumpeted as a major new finding, hasn’t it been obvious for at least the last few years that biofuel carbon neutrality is very dependent on how land use patterns change?

    Water Find to End Darfur War – Well, not so fast!

    Byoliveridley

    Beware the dangers of the overhyped press release machine (or sciencedaily, pick your poison). All Farouk El-Baz saw when he did the radar study was a giant depression. It is TBD whether there’s water in them thar holes!’

    BBC NEWS | Africa | Ancient Darfur lake is dried up

    Alain Gachet, who used satellite images and radar in his research, said the area received too little rain and had the wrong rock types for water storage. But the French geologist said there was enough water elsewhere in Darfur to end the fighting and rebuild the economy.

    On Wednesday, Boston Universitys Farouk El-Baz said he had received the backing of Sudans government to begin drilling for water in the newly-discovered lake, in North Darfur.

    No wonder they say that water is the 21st century oil. This guy’s going to be drilling for water (also known as well digging!).

  • Scary Energy Consumption Trends

    Byoliveridley

    Per capita energy

    Data courtesy World Resources Institute. As you can see, the people of up and coming powers India and China use barely use 10% the energy per person compared to the US/Canada and will be thirsting for more in the coming years. Of course, they will never get to the same per capita use because population density and crowded housing makes for a lot of energy efficiency.

    China is going coal in a big way. A NY Times article last week spent 5+ pages on this subject. Coal is dirty, dirty, dirty. Coal puts out copious amounts of CO2. Of course, conventional coal fired power plants also pollute in ways that temporarily mask greenhouse effects, both from direct particle emissions and sulfate formation from sulfur in the coal. These effects are localized and temporary, and have pretty serious short term health consequences.

    India is going coal too, being the third largest producer in the world. At least, there is lip service being paid to clean coal/gasification, and increased use of natural gas.

    The world is going to get worse before it gets better…

  • Big Wool and Fast Fashion

    Byoliveridley

    Cute sheep or not, factory farming is always impactful

     

    According to one analysis of wool production in Australia, by far the world’s top exporter, the wool required to make one knit sweater is responsible for 27 times more greenhouse gases than a comparable Australian cotton sweater, and requires 247 times more land.

    Source: Big Wool wants you to believe it’s nice to animals and the environment. It’s not.

    This is an interesting article in Vox on the outsized impacts of large-scale factory farming wool impacts. The article goes into further detail comparing wool to synthetics on impact (Both big, but different), and why plant-based alternatives like Tencel and Hemp and recycling have not taken off. It also discusses the increasing trend of wool blends.

    Widespread cheap synthetics have enabled fast fashion, making it possible for brands to produce stupefying volumes of disposable fabrics. These are now very commonly combined with wool to create hybrid garments. According to the Center for Biodiversity and Collective Fashion Justice’s recent analysis of 13 top clothing brands, more than half of wool items were blended with synthetics, giving them in-demand properties like machine washability

    Of course when you blend a wool and a synthetic, it is now landfill material. The issue with clothing (same as the issue with most scaled up factory production) is scale and economics. Fast fashion makes clothes that fall apart in 6 months and are impossible to fix. So whatever the raw material used, this trend ensures high production, quick profit, large impact and large waste. In addition, factory-scaled animal production is not really compatible with animal welfare.

    Unless the system changes, which will require a massive re-examination and re-jigging of our financial systems and reward/responsibility mechanisms, we will always have this issue.

    India's Environmental Portal

    Home | India Environment Portal

    This is a very useful undertaking by the Centre for Science and Environment (CSE) to gather up a lot of technical information about India’s environmental research and activism.

    They have a small multimedia section as well and I found this movie, appropriately titled Faecal Attraction to be an informative watch…

  • 'Shocking' conditions at Kenya dump

    Byoliveridley

    B26F0EF1-45A5-4229-9FE0-83784AA06DBC.jpg

    As part of blog action day, today’s a day when every blog features a post about the environment. Turns out that this is an environmental blog where most of the posts are about the environment. But nothing like a deadline for a noble cause to make me blog, so here goes…

    What the rich use and throw away, the poor are reduced to scavenging to earn a meager living. Yes, while climate change rightly takes up a lot of attention, more mundane problems including landfills in poor communities, the export of waste from the first world to the third world, and the “shocking” poverty that drives this export of waste all deserve their fair share of attention.

    U.N.: ‘Shocking’ conditions at Kenya dump – World Environment – MSNBC.com

    “Willis Ochieng, 10, scavenges through smoking refuse piled as high as a house at one of Africa’s biggest rubbish mountains, his friends sitting nearby sucking on dirty plastic bottles of noxious yellow glue.

    Located near slums in the east of the Kenyan capital Nairobi, the open dump receives some 2,000 tons of garbage daily. A U.N. study published on Friday says it is seriously harming the health of children and polluting the city.”

    And boy, do the people there suffer. Asthma, anemia, high levels of lead in the blood, chronic cough, and a smorgasbord of other acute and chronic conditions.

    This dump is not alone, of course. Landfills are a feature of every country, and in my current home state of North Caroiina, are located with disproportionate frequency in African American communities. the free market advocate would say that this represents an opportunity for the people in the community to gain some employment and make some money. The truth of the matter, however, is that we do not pay the right price for waste generation. The people who live near, and make a living off the “dump” subsidize our profligate selves.

    Pesticide Exposure and India's green revolution

    Byoliveridley

    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.
