Michael's Dispatches

Gobar Gas II



In Laos, 'Gobar Gas' is called 'Gaz Sivulphap.'  The program is not sparking as well in Laos as elsewhere, perhaps because they still have many trees.  They don’t have to walk far or pay for wood.

Aussie Andrew Williamson from the Dutch SNV, and Bounthavy Sengtakoun, his Laotian compatriot, examine a biogas lamp in Laos.  This house has electricity but biogas is cheaper.  A biogas lamp, similar to an LPG camping lantern, can cost anywhere from US$3 to US$15 depending on quality.

Cambodia: light in many homes is provided only by battery.  A small business that uses a generator charges the village batteries.  If you are in a jam in a village like this, and need your sat phone or cell phone charged, find one of these places and they’ll wire you up while you have tea.  In Iraq, some people charge cell phones on motorcycles.

In addition to the health advantages of biogas for women and children, the rest of nature also benefits.  Birds and other creatures do better when trees remain standing. In Nepal a single biogas plant can save about 2,500 kilograms of wood per year.  Trees anchor topsoil and prevent erosion.  In some places, the wood is simply gone.

The people of Bhatti—a village whose business is making moonshine—said they had heard about Gobar Gas but never wanted it.  Wood for cooking and making raksi (rice whiskey) was plentiful.  But they burned through all the wood—destroying the local economy.  LP, kerosene and other fuels are too expensive to use in making moonshine. So the entire village of nearly a hundred people began travelling—up to three days to and fro—to buy wood from other places.  Even the men had to spend their time scratching for wood—a situation too humiliating to stand.  Gobar Gas started flowing in Bhatti in November 2009.

Lizard Hole

Dung piles in Karbasha Qalat, Afghanistan

Ghor Province, Afghanistan is similar to dry parts of Nepal.  In Ghor there is a village called Karbasha Qalat (Lizard Hole) populated by a cow, sheep, horses, dozens of people, and thousands of lizards.

Villagers dry the dung in the sun and collect it into huge stacks, as people do in India, and Nepal, and across many places.  Karbasha Qalat (KQ) is like a dry Galapagos with all those lizards basking in the sun atop rocks and dung.  Unlike the islands, KQ is not at sea level, but over 8,000 feet.

In some places Afghans tell stories about today’s barren mountains having been covered by forests.  If there ever were trees around KQ, they are gone. The wild plants that can survive here must be bitter to man and beast.  There is no local wood.  When the manure is burned, it chokes those nearby, and then it is gone.  If KQ had a biogas generator, tons of manure would make gas while yielding slurry, to fertilize the now barren land.  And there wouldn’t be human and animal feces everywhere—a serious hygiene improvement.  The villagers in KQ had enough manure piled up to fuel a rocket with Gobar Gas.

Lizards atop dung cakes in Karbasha Qalat.

Ten kilos of dung yields roughly an hour of stove burning time, and one of those skinny cows produces about 12 kilos per day.  KQ had a great herd of sheep—probably a couple hundred—kept in pens when not out feeding.  Villagers scrape sheep dung from the pens, which they mixed with cow (I saw only one), mule and horse manure for cooking.  A small stream runs through the village.  Afghans will use greenhouses if taught; I’ve seen them in Helmand and Oruzgan.

An outside stove in KQ.  Many Afghans cook indoors.

The bio-slurry from the digester is so effective for growing crops that in some countries, according to Mr. Rai, biogas is not an energy program but an agricultural initiative. In Vietnam it has been adopted for sanitation.  The biogas and the great sanitation benefits, including reduction of waste-borne diseases, are byproducts in one place and impetus in another.  In Karbasha Qalat, with a few greenhouses using the bio-slurry, the standard of life could dramatically improve.  There must be thousands of “Karbasha Qalats” in Afghanistan.

SNV: The Dutch Connection

The more one learns about biogas, the more one sees the Netherlands Development Organization (SNV) humming in the background.  SNV started working on biogas in Nepal in 1989, further adapting the Chinese technology (the system is used across China), and developing an effective market-based program model.  The Dutch could not be accused of looking for short-term solutions or following the crowd.  Fifteen years in, SNV decided their domestic biogas program model was ready to replicate elsewhere in Asia.  They started the program in Vietnam in 2003, and the Asia Biogas Program targeting 1.1 million beneficiaries in Vietnam (second phase), Bangladesh, Cambodia and Lao PDR in 2005.

Wim van Nes, one of the world’s leading experts on the subject, is in charge of supporting SNV’s biogas programs in fourteen countries, seven in Asia and seven in Africa.  And so I had to find Wim van Nes, but that comes later.

Kitchens in Laos are better ventilated than many in Nepal or Afghanistan.

    I love your articles about this excellent technology, Michael. I recently read an article in my local newspaper about an entrepreneur here in Georgia (USA) trying to make a large-scale gobar gas plant running off cow crap from all the farms, I got so excited after learning so much about it from you.

    Mr Yon;
    Very interesting article. Gobar gas would seem to have potential in Afghanistan unless lack of water makes it impractical. I'm a farmer so I have a different perspective on manure. I suspect that farms in Afghanistan need all the manure they can get given the low organic matter of soils in a dry climate. The easiest way to apply manure is to graze either crop residues or crops grown for grazing; the problem in Afghanistan is enough water to support both. Ideally you grow a grazing crop after harvesting a grain or other cash crop using rainfall during the "wet" season usually the winter in desert areas(snow counts as rain). Wheat and barley can be grazed when young but animals must be removed when the grain crops starts to grow rapidly. Manure can also be applied by collecting it from pens and spreading it by hand. I doubt that there is a labor shortage in rural Afghanistan.
    Soil organic matter is the single most important factor in maintaining productive erosion resitant soils. Fertilizers have a place but will not maintain soil organic matter levels by themselves. Manures and good crop rotations are vital, a fact lost to most US farmers. The PRTs could use some organic farmers who know how to build healthy soils. Besides fertilizer cost money, maunure does not. The answer to developing Afghan arigulture is not the wholesale blind adoption of modern technology but adapting methods to facts on the ground. For example, improving animal drawn implements can improve crop yields just as much as mechanization without the cost of equipment,fuel and parts. Again there is no shortage of farm labor so why bother to mechanize.
    Several NGOs have developed portable solar cookers in Africa which cook meals with no wood. This approach might be more adaptable to Afghanistan than gobar gas.

    In your article you eluded to the difference between Afghanistan and Nepal where in Nepal there is unity between the ethnic groups, whereas in Afghanistan much less. What do you consider to be the reasons for success in the one county and failure in the other?
    Thank you so much for your writings and photos. You help me understand so much better the complexities of the conflicts.

    I love your articles, however, it’s obvious that you are just spinning your wheels. With all of the time you spent in Iraq reporting the truth about the war it pains me to see the military deliberately sidelining you when they could using you to win the hearts and minds of the people here at home.
    Every time I see a report on the evening news with an ”In Depth Report From Afghanistan” it is quite obvious to read between the lines and watch those in-experienced “war journalist” scared witless when a shot is heard in the distance and far out of range. Their focus on the report is so scripted it sounds like it was written by a PsyOps officer and censored extensively.
    The quality of those reports is completely lacking and always reminds me of the Russian propaganda machine when the Russians occupied Afghanistan.
    All I see from the reporters today is a whitewash of the reality of the war and the Big Brass patting themselves on the back for the failures they claim as victories.
    When you were there reporting we could trust that we were really getting the truth. Now, every word out of Gen McCrystal’s mouth sounds just like the bumbling Russian Generals all over again.
    We no longer get to see and hear about our sons and daughters and the sons and daughters of Great Britain and other countries. Even though a report may have been of someone else’s son or daughter those reports from you were our lifeline to them.
    It’s quite obvious that your boot from the war zone is retribution for exposing the failures and to cover up their continued failure in handling the war. Frankly, I believe that McCrystal and his whole command needs to be fired for lying to the American people.
    McCrystal is a joke in the eyes of many people here at home. I don’t care how many people speak up for him. He’s still a joke to me.

    Michael -

    Excellent articles. My wife and I got turned on to an orphanage in Cambodia that saves kids from a life in the Steung Meanchey dump, among other things. A buddy of ours took some incredible pictures there, his style reminds me somewhat of yours... check www.anthonysloan.com if you have a chance. That said, it would seem to make sense to get in good with these orphanages... they are taking these incredibly disadvantaged kids and turning them into savy little business people. This one in particular, Cambodian Childrens Fund www.cambodianchildrensfund.org seems to do good work (and no, I'm not affiliated with it in any way). It might make sense for some of these Gobar Gas folks were to install gas facilities at the orphanages. The kids grow up understanding the benefits of the technology without having the cultural baggage that may otherwise be attached. Of course, I'm not sure if they have enough little kids or chickens to run the thing... :-) I'll forward your articles to them... if it makes sense for them I'd sure kick in a few $$$.

    I was completely engrossed. I would expect to see full-issue articles of this caliber in NatGeo or The Economist. Have you submitted? Looking at the relatively low cost for residential installation, I almost want to give directly to subsidize these myself. Is there a charitable fund (with high flow-through percentage) dedicated to helping this international effort? All the money we pay in taxes and fees, yet a direct contribution would have such a longer-lasting and immediate impact.

    Fantastic work. Thanks for the full-dispatch 'fix'. Looking forward to more.

    Great job on this find. I stumbled across Gobar gas two years ago for my public policy course when searching for ways to reduce CO2 output while improving agricultural output (a next to impossible assignment given to me by my lecturers). It was the near-perfect solution with few drawbacks, great for farmers and also for appeasing the greens. My lecturers, alas, did not quite appreciate a technical solution, and were looking more for a political strategy to solve the problem.

    As a political animal, Obama is likely the same. In addition, he is either too stupid or too traitorous to even consider this approach as part of a nation-building initiative.

    PS. I'm not even an american!

    This would dovetail nicely with permaculture, a gardening-lifestyle schema that makes incredible use of rainwater and mulch and native perennial plants. Permaculture is also a bottom-up type thing, which is never sexy so it never gets talked about.
    If these two ideas made love I am pretty sure that we can solve the base problems of the world.

    Great article mate! As one of the co-respondents mentioned above, the use of animal dung may be limited but depending on social standards, human waste may be substituted. Whatever the case, this is such a great idea to adopt! The Ghurkas and Afghans have a natural affinity for one another and I would encourage the parties that be to adopt this as a urgent development approach.................utilise the Ghurkas as an acceptable means fo getting this started with the local population in Helmand province at least.

    I believe by having some of the Nepalese representatives and the Gurkha soldiers leading this idea for a Gobar Gas system would be brilliant. Since both the Nepalese/Gurkha and the Afghans share so many similarities...what better way to bring in modernization to the Afghan people than by having a representative force/group that can teach them and mentor them in producing biogas collection systems. Not only would it help the economy and the Afghan population but it would also deplete the very frustrations of lack of electricity, gas/fuel, work, and oppotunities that the Taliban and insurgent groups have been feeding off of.

    If the Coalition and the governments that are part of it are truly seeking a way to get of Afghanistan and help in its reconstruction and build up...than using the simplest methods is probably the easiest and in the long run the best. Provide the Afghans with renewable resources and as seen by the example of how Gobar Gas allowed kids to attend schools will help develop a generation of educated people who can lead their country to better things. Deprive the Taliban their greatest resources: frustrated civilians (due to shady government and police forces), lack of jobs (gives the farmers and villages if they use this Biogas system more time to grow crops or learn trades), lack of money (sell your part of the biogas to others or vice versa teach and build systems for others), lack of security (by building a stable economy and a renewable resource for energy and such a village or city like Kabul can train better soldiers and police officers who will be paid decently).

    There is so much potential from this idea. Please Michael if you can gather a group of Nepalese businessmen, soldiers, mentors and so forth and do a test program in a village where you can see if indeed setting up a biogas system for the villagers for each house would do the trick in modernizing and helping the Afghan people in the long run!

    Plus, if there is a donation system I would love to know about this too. A microfinancing system would work great or even simply a charitable donation would do the trick.

    Hello Michael,
    Another fantastic and informative dispatch. Thanks. I have 2 questions about the viability of gobar gas in Afghanistan:
    1- is there enough water in most areas to make it feasible? Areas like the "green zone" seem like they would, but much of the rest of the country seems like it would not. But perhaps their wells would be able to sustain the units.
    2- I read recently (I think it was from a link from your site regarding the "new" mineral deposits in country) that Afghanistan has a pathetic, almost non-existent, concrete industry. Something like less than 2 kg/person per year. Due to that scarcity of concrete, are there other materials that could be used to make the units? Or are there plans to ramp up concrete capacity (outside of the mining industries)?

    Keep up the great work!

    hello Michael.
    It's nice to get more info about Gobar gas. As you said during your visit in Ghor in 2009, these people might use Gobar gas if they know how to do this. let's hope that one day they will discover what kind of benefits Gobar gas might give them
    good luck in your future dispatches!

    Thanks for this informative article, really good stuff. Now I feel guilty about a comment I put on the Bangkok dispatch trying to give constructive criticism. This post about Gobar Gas is what I consider "classic Yon", an excellent in-depth coverage of a topic, with great photos, such that from my chair in Florida, I feel like I just took a pleasant trip and met interesting people and got an intimate knowledge of a specific thing. Previous dispatches in Afghanistan about the artillery units, the Pedros (did I remember that right? I mean the medivac helicopters), or accompanying Brits as they patrol on foot, are similar examples of what I'll call "classic Yon". Anyways, enough scrutiny of your style and content. Great article, and great idea (that Gobar Gas could be good for Afghanistan). Thanks.

    Note: Mr. Welborn - you had it right, Mr. Yon wrote an excellent article on the Pedros in Helmand Province. Those guys are still there and the Pedros actually suffered many casualties very recently when their bird was shot down. Let's all pray that there are no more casualties.

    Regarding this article:
    As a Master's student at UF's Ecological Engineering program, it's really great to hear about ecological engineering from a predominantly war-focused correspondent in an article that describes the benefits of the technology. In order to solve the energy, economic, and social problems of the world, we have to look to old-fashioned technologies that maximize the efficiency of natural processes (processes such as decomposition, described here). Nature provides all that we need, we just need to figure out how to use it efficiently and not wastefully. Your description of the villagers having to travel for more than 4 hours to find enough wood to cook is akin to the fall of the Roman empire due to deforestation and the near extinction of Easter Island residents due to the same reason. These modern-day villagers will continue to have to travel farther and farther to find wood, until it is completely unsustainable. An unsustainable lifestyle, whether it is McMansions and Hummers [already failed] in the US or wood-burning cook stoves in the deserts of Afghanistan, will eventually lead to more poverty and the social problems that come along with it (like joining the Taliban for some cash).

    Mr. Yon, you have an excellent view of the world and I hope that more people will realize that it will take just as much social investment in MEANINGFUL programs as it takes in military investment to defeat the Taliban.

    How about some comments on the "recent discovery" in Afghanistan of a trillion dollar's worth of gold, silver, copper, iron, and lithium? My first thought was, "yeah right, this was known all along because the Soviets knew about it in the 70's and 80's." And it all made sense to me, Afghanistan doesn't have oil, but heck, they have natural resources that might end up being just as good if not better, especially if lithium for batteries turns out to be a "gold mine" for modern technology.

    Hi Michael,

    This is fascinating. I am going to Tanzania on Saturday to work on a development project and I will be thinking of this work while there. Can you tell me how I can get my hands on the book recommended above, please?

    In addition, I am working on an anerobic digestion project currently so I am very excited at the prospects of this.

    Thank you for this enlightening article.

    The biggest cause for the degradation of environment is burning of fossil fuels

    Burning of coal / gas / oil etc produces green-house gases , leading to global warming / floods / droughts etc

    Everyone knows that the real long term solution is switching over to renewable energy sources such as wind / sun / tides etc

    Can we tap earth's magnetism to produce abundant / unlimited / clean energy ?

    I believe so and would request the scientists to consider my following suggestion :

    Every school child knows that ,

    > Electricity is generated when a copper wire is
    rotated in any magnetic field

    > Earth is surrounded by a very strong magnetic

    > This magnetic field is generated by the rotation
    of molten iron deep inside earth's core

    > This magnetic field also protects us from

    harmful ultra-violet rays / gamma radiations

    from space

    Now , suppose we find a way to ,

    > Construct a hollow cylinder of woven Copper

    wires to envelope the earth , 100 miles above

    the earth's surface ( like those thin rings of

    Saturn ? )

    > Then , using small rocket thrusts , rotate this

    cylinder in the direction opposite of earth's

    rotation , to cut through its magnetic field

    Will that generate electricity ?

    I think so

    With international co-operation such a project would take less time - and possibly money too - than the already successful international projects of the International Space Station or the Large Hadron Collider of CERN

    It may be exciting to discover the God Particle and understand what makes up mass but I think , it is far more useful to find a permanent / clean source of energy to prevent the extinction of all life on earth by burning fossil fuels
