Organic agriculture can feed the world

That’s the conclusion reached by the authors of this study based on 293 examples in the developing and developed world.The authors also conclude that yields in the developing world are higher for organic agriculture than for conventional agriculture. Why? Well, since the paper is not open access, I can’t read it, or critique it, I’ll have to wait to get to the library before I can download it. But, maybe it’s because organic agriculture tends to be more labor intensive than conventional agriculture as practised by the developed world, and in the developing world, labor is cheap!

Anyway, this is a good news study and should be examined a little more thoroughly.

CJO – Abstract – Organic agriculture and the global food supply

The principal objections to the proposition that organic agriculture can contribute significantly to the global food supply are low yields and insufficient quantities of organically acceptable fertilizers. We evaluated the universality of both claims. For the first claim, we compared yields of organic versus conventional or low-intensive food production for a global dataset of 293 examples and estimated the average yield ratio (organic:non-organic) of different food categories for the developed and the developing world. For most food categories, the average yield ratio was slightly 1.0 for studies in the developing world. With the average yield ratios, we modeled the global food supply that could be grown organically on the current agricultural land base. Model estimates indicate that organic methods could produce enough food on a global per capita basis to sustain the current human population, and potentially an even larger population, without increasing the agricultural land base. We also evaluated the amount of nitrogen potentially available from fixation by leguminous cover crops used as fertilizer. Data from temperate and tropical agroecosystems suggest that leguminous cover crops could fix enough nitrogen to replace the amount of synthetic fertilizer currently in use. These results indicate that organic agriculture has the potential to contribute quite substantially to the global food supply, while reducing the detrimental environmental impacts of conventional agriculture. Evaluation and review of this paper have raised important issues about crop rotations under organic versus conventional agriculture and the reliability of grey-literature sources. An ongoing dialogue on these subjects can be found in the Forum editorial of this issue.

    Stealth sharks to patrol the high seas

    More controversially, the Pentagon hopes to exploit sharks’ natural ability to glide quietly through the water, sense delicate electrical gradients and follow chemical trails. By remotely guiding the sharks’ movements, they hope to transform the animals into stealth spies, perhaps capable of following vessels without being spotted. The project, funded by the Defense Advanced Research Projects Agency (DARPA), based in Arlington, Virginia, was presented at the Ocean Sciences Meeting in Honolulu, Hawaii, last week

    Read the Tom’s Dispatch article for a bigger picture look, excellent paragraph here, one can’t help but wonder…

    To support letting inventive minds roam free outside normal frameworks is in itself an inspired idea. But I bet there’s no DARPA-like agency elsewhere in the government funding the equivalent for education 2025 or health 2025 or even energy independence 2025. To have this happen, I’m afraid, you would have to transform them into Northcom war games.

    I do not believe that throwing money into research solves all problems, but I wonder what would happen if the US of A did not spend all its spare cash and (up to the eyeballs) in debt on defense. The incredible amounts of money spent on defense makes many people rich, keeps many companies afloat, creates many jobs, etc. But so would massive amounts of government funding on pretty much any other, more worthwhile venture.

  • Movement on Texas Coal Fired Power Plants.

    There’s been some progress on the coal fired power plants I had railed on about recently.
    In Big Buyout, Utility to Limit New Coal Plants – New York Times

    Under a proposed $45 billion buyout by a team of private equity firms, the TXU Corporation, a Texas utility that has long been the bane of environmental groups, will abandon plans to build 8 of 11 coal plants and commit to a broad menu of environmental measures, according to people involved in the negotiations. The roster of commitments came through an unusual process in which the equity firms asked two prominent environmental groups what measures could be taken to win their support. The result is an about-face from the company’s earlier approach to climate-change issues, and includes a goal of returning the carbon-dioxide emissions by TXU to 1990 levels by 2020. Environmental groups said yesterday that they had never known of a financial deal with such an ambitious built-in environmental component.

    Better than nothing. This is good news for sure. But as I mentioned previously, the Sanders (Good ol’ socialist!) Bill calls for an 80% reduction from 1990 levels by 2050. This is required to cap CO2 levels at 450 ppm and avoid the worst effects of global warming. So, while reducing CO2 to 1990 levels sounds impressive in a breathlessly written NY Times article. It is not nearly enough. This is exactly what I was afraid of when I mentioned the moratorium word! In the absence of regulation, or a clear policy, private equity companies, power plants, and other plutocrats are setting the US global warming agenda. They are establishing the floor plan, meaning, we’ll set the bar near the floor and not budge. Yes, I know, the NRDC and Environmental Defense were involved, and this part is definitely good…

    TXU will discard plans to build eight of 11 proposed new coal plants, which would have been major new sources of emissions. Those plants — which would have added more than 9,000 megawatts of new capacity, the equivalent of 3.5 percent of the nation’s current coal-fired power — had been part of a planned $10 billion expansion of coal-fired electricity.

    TXU, which is based in Dallas, also intends to expand the renewable energy portion of its portfolio and reduce or offset its emissions significantly, said people who were familiar with the plans.

    All very good, but as I talked about previously (man, way too much self reference, not a good thing!), a book called Reality Check just out assesses voluntary actions by various companies in the US, Europe and Japan and comes to the following conclusion:

    Most of the programs it studies have positive results, but they are
    small compared with business-as-usual trends and the impact of other
    forces–such as higher energy prices. Importantly, potential gains may
    be quickly exhausted as the “low-hanging fruit” is picked up by
    voluntary programs.

    Now tell me that this agreement does not fit this frame!

  • Pesticide Screening Using a CD Player and CDs.

    Who said CDs were dead, this is, hands down, the coolest paper on screening techniques I have seen in a while. I haven’t seen the rest of the paper, not Open Access, of course, but the abstract does make it sound cool.

    Microimmunoanalysis on Standard Compact Discs To Determine Low Abundant Compounds

    “High-density competitive indirect microimmunoassays were performed in both sides of compact discs by direct absorption of immunoreagents on polycarbonate surface, using gold- or enzyme-labeled immunoglobulins as tracers for displaying the immunoreaction. The operational principle is based on the use of a low-reflectivity compact disc as analytical platform that allows the reflection/transmission (30/70%) of the CD reader laser beam ( 780 nm). The reflected light is used to scan the disc track keeping it in movement. The transmitted light is detected by a planar photodiode integrated on the CD drive. The variation of the optical transmission of the light caused by the immunoreaction products is related to the sample concentration. As a proof of concept, low abundant compounds, commonly used as pesticides, were detected in a 60-min total assay time, with a limit of detection ranging from 0.02 to 0.62 ug/L for 2,4,5-TP, chlorpyriphos, and metolachlor. The obtained results show the enormous prospective of compact discs in combination with CD players for multiresidue and drug discovery applications.”

    Why are techniques like these important in the world of environmental analysis? Because they change the paradigm from laboratory based techniques to field based analysis. You don’t have to take a bunch of samples, spend a lot of time and money shipping them to a lab and waiting for the results. You can pop your samples into a CD player and one hour later (less than a 74 minute listening time on a CD!), you’ll have results.

    Awesome stuff, I’d love to see it in action, or even try to replicate the work. It looks like you have to make some modifications to the player to make it work, but hey, there are millions of CD players that are going to be obsoleted in the next few years.

    India goes solar

    India, of course, gets a lot of sun, it is wasted in the sense that it makes us sweat, causes us to use increasing amounts of electricity for air conditioning, and all in all, is a pain. So, a plan to use that sun to generate solar energy, of course, is very welcome. Solar energy use obviously is not new in India, my best friend growing up had a solar water heater at home (his family business used to make them). Policy has never kept up because there has not been a push, is this one?

    The Union Government has finalised the draft for the National Solar Mission. It aims to make India a global leader in solar energy and envisages an installed solar generation capacity of 20,000 MW by 2020, of 1,00,000 MW by 2030 and of 2,00,000 MW by 2050.

    The total expected funding from the government for the 30-year period will run to Rs. 85,000 crore to Rs. 105,000 crore. The requirement during the current Five Year Plan is estimated to be Rs. 5,000 crore to Rs. 6,000 crore. It will rise to between Rs. 12,000 crore and Rs. 15,000 crore during the 12th Five Year Plan.

    A crore, BTW, is 10 million. India still uses its own number multiplier system for money that goes in 100s, not thousands. So, a 100,000 is a lakh, and a 100 lakhs is a crore. I never understood why this was not changed when the country went metric. Lakhs and crores, of course, are metric, but can get confusing.

    The plan will start off by mandating roof top solar panels for government and government owned industry buildings in an attempt to reduce costs by scaling up. It will be followed by mandated solar water heaters for all commercial buildings and apartment complexes, and use of solar panels for all in industrial buildings. All this is supposed to happen in the next three years, which appears to be wildly ambitious.

    India is a federal country with delineation of jurisdictions between the central and state governments on regulation. Electricity happens to be on the concurrent list, meaning both the state and central governments can make laws, and the central government’s laws will always preempt the states. However, building appears to be a local government issue, so managing this huge transition could get tricky. They are all supposed to use the same building code, but given the unevenness of local governance, who knows what implementation will look like.

    In Phase II, starting 2012, India will go solar thermal. India and Pakistan have 200,000 sq km of the Thar Desert, a typical dry tropical desert with oodles of space and sun. It would be a good place to site all kinds of capacity similar to efforts in North Africa and Spain.

    Solar thermal, if combined with the right kind of transmission and storage technology, could power the world in 7000 sq km, so theoretical capacity may not be an issue. Of course, the storage and distribution are key. Molten salt batteries look very promising for solar energy storage and night use.

    India’s electricity needs are daunting. This WolframAlpha search provides the following:

    IndiaCanada

    Note to Wolfram: your data presentation would result in a failing grade on a middle school term paper, where are the sources? Where did you get your numbers? BIG FAIL!

    We in Canada use more electricity than India for about a billion fewer people. Clearly, if India was as profligate as Canada in energy consumption and got the power it needed to get there from coal, we would all be dead soon. India needs to go solar in a hurry and I am glad the government has released a policy that is more ambitious than the US or Canada. It needs the support and funding to make it happen and I for one will be very happy to see progress in this area. Solar power needs big up front costs and little ongoing costs.

    Can Indian industry provide the money needed? We shall see. I am not too worried about the photovoltaic panel parts, they will muddle along in typical patchwork Indian fashion with the quality of governance being the controlling factor in success or failure. It is the capital and political will needed for solar thermal that strikes me as problematic. The coal and mining industries are entrenched in some population (and vote) rich states like Bihar based in the central and north east regions and there could be some big losers if India went away from coal (as it needs to in order to prevent catastrophic climate change) and toward solar thermal, which I assume would come out of Rajasthan (West).

    Anyway, we live in interesting and sunshiny times, stay tuned for more.

    On Google map, everythings back to normal after Katrina | Chron.com – Houston Chronicle

    TBTB (Too busy to blog), but this struck me as very weird.

    On Google map, everythings back to normal after Katrina | Chron.com – Houston Chronicle

    Google’s popular map portal has replaced post-Hurricane Katrina satellite imagery with pictures taken before the storm, leaving locals feeling like they’re in a time loop and even fueling suspicions of a conspiracy.

    Scroll across the city and the Mississippi Gulf Coast, and everything is back to normal: Marinas are filled with boats, bridges are intact and parks are filled with healthy trees.

    “Come on,” said an incredulous Ruston Henry, president of the economic development association in New Orleans’ devastated Lower 9th Ward. “Just put in big bold this: ‘Google, don’t pull the wool over the world’s eyes. Let the truth shine.’ “

    I am sure there is the usual, non-conspiracy involving explanation to all of this, and I don’t know enough about NO geography to even verify this fact, but an explanation would be nice!

    Update:

    Turns out there was a major upgrade of the imagery on the 29th of March. Still does not explain the above…

    California’s Prop 65 on Deathbed

    House votes to dump state food safety laws

    See this post for some context.

    The vote Wednesday was a sign of the tremendous power of the food industry in Congress. Corporations and trade groups that joined the National Uniformity for Food Coalition, which backed the bill, have contributed more than $3 million to members in the 2005-06 election cycle and $31 million since 1998, according to data from the Center for Responsive Politics.

    The industry also has many top lobbyists pushing the bill, including White House Chief of Staff Andrew Card’s brother, Brad Card, who represents the Food Products Association.

    Well, will it die in the senate? One wonders.

    Why bother with an elected goverment if all it does is pass bills written by big industry? Maybe it’s time to get the middlemen out and have big business actually run the country, maybe GM can take a shot! Or maybe the top guy on the Forbes list for the year can take over as president for the year, this will give Warren Buffett good incentive to knock off Mr Gates.
