A Gurkha Idea
Among the more interesting coalition forces fighting in Afghanistan are the legendary Nepalese Gurkhas. Trained and fielded by the British, as they have been since colonial days, Gurkhas are a fascinating admixture: today, they are elite soldiers used to traveling the world. But many of them grew up barefoot and poor in remote and primitive mountain villages in the high Himalayas—places that closely resemble parts of Afghanistan, geographically and culturally. Forefathers of some of today’s Ghurkas fought in the Afghan region during earlier wars. Gurkhas understand impoverished life in a harsh environment, though Nepal has enjoyed material progress in recent decades that is mostly unrealized in Afghanistan. Unlike forces from Europe or America, who often regard Afghanistan as an outpost of 13th Century life, Gurkhas can provide a link between primitive Afghan standards of development, and the possibilities for progress, with insights and connections that might elude most Westerners.
The insights of a Gurkha veteran named Lalit, whom I met in the jungles of Borneo, at a British Army man-tracking school, were particularly valuable. One day in the jungle Lalit began a conversation by announcing that many of Afghanistan's household needs could be solved if Afghans would adopt "Gobar Gas" production. Gobar Gas could improve the lives of Afghans as it had that of the Nepalese, he said, as he began to explain with great enthusiasm.
During Lalit’s time in Afghanistan, he found nobody who had heard of Gobar Gas—even though Gobar Gas has been a quiet engine of ground-level economic transformation in Nepal and numerous other poor Asian nations.
After the man-tracking course ended I returned to Afghanistan, this time to the desert-like areas of Ghor, Helmand and Kandahar provinces, where most people have no electricity and often spend hours daily scrounging for bits of wood or whatever other fuel they can find on the deforested plains. Lalit was right about two things: No Afghan I met had heard of the Gobar Gas – by any name. Nor had most American development people on the ground. Second, Gobar Gas looked like a serious solution in some areas to the lack of available fuel to meet daily needs. Given its track record and its perfect applicability to Afghanistan's state of development, this was a match made in heaven. I flew back to Nepal to talk with Gobar Gas experts and users. (A full explanation follows shortly.)

Kathmandu, Nepal
Physically, Nepal and Afghanistan share similarities. Both contain great mountains and are difficult to navigate due to lack of roads, while existing roads are frequently impassable. The mountains and weather can be brutal. This is compounded by lack of electricity, transportation, communications technology and just about anything else associated with modern societies. Both countries have been saddled with weak and corrupt governments, universally mistrusted. They each have about 30 million people—80% of whom are subsistence farmers—living in small villages. The median age in both places is under 20, suggesting future crises. Half of the Nepalese are literate; perhaps a third of Afghan men can read, now, in the opening decades of the 21st century.
The desires, complaints and problems in both places often run parallel. Sizable populations are isolated for months each year by snow, rain and landslides—or just lack of bridges. Government influence in both countries mostly ends where the paved roads end. (Though Nepal actually has a government of sorts, and not surprisingly, far more roads.) In the hinterlands, life remains primitive, and in some cases, quite literally, prehistoric, except that outsiders note their existence. Government edicts and ideas issued from Kabul or Kathmandu are unheard or ignored—the words might as well come from Timbuktu or the Moon.

A remarkable difference in Nepal is that most ethnic and religious groups coexist reasonably well, and despite their recent civil war the Nepalese seem considerably less prone to warlordism, general violence, and especially violence directed toward outsiders. Even during peak wartimes I had no difficulties walking hundreds of miles through contested areas in Nepal. While Nepalese fought each other, all sides (other than occasional criminals) protected travelers. Travelers who want to visit Kathmandu and trek the Himalayas are the country’s good fortune. Though Nepal is one of the poorest, least developed countries on Earth—and despite rampant corruption and recent war—progress is perceptible.
Nepal is arguably a half-century ahead of Afghanistan in governance, education, press, and certainly in tourism. Nepalese old-timers say that in the 1950s and 60s, for instance, few boys, and almost no girls outside the ruling elite, went to school. There has been steady progress in the numbers of citizens educated in Nepal. A visitor will see school children in many districts, even deep in the mountains, wearing uniforms and often walking 5-10 miles to school, as our grandparents once did in America. Democracy was first tasted in Nepal in the 50s, but did not truly take hold until 1990s. The democracy is struggling and fragile, but trend lines are good. (Educated Nepalese could mount valid arguments contradicting my statement.)
Though Nepal remains poor and underdeveloped by Western standards, if Afghanistan were to reach Nepal’s level in a few decades, some might rightly consider that a great success. And so, for me, Nepal has become a sort of looking-glass for Afghanistan. It’s a good place to search for insight and ideas that might be applied in Afghanistan. The Gurkha idea for Gobar Gas in Afghanistan was a pearl from Nepal.
Dung
acc-730.jpg)
“Gobar” is the Nepali word for cow dung. The “Gas” refers to biogas derived from the natural decay of dung, other waste products, and any biomass. In Nepal, villagers use buffalo, cow, human, and other waste products for biogas production. Pig and chicken dung are used in some places, as are raw kitchen wastes, including rotted vegetation.
Gobar is typically mixed with a roughly equal amount of water, and gravity-fed through a pipe into an airtight underground “digester,” where naturally occurring bacteria feast on the mixture. This anaerobic process produces small but precious amounts of gas. That gas can be fed directly into a heat source, such as a cooking stove, and used to fuel it.

The biogas is 50-70% methane by volume, similar to natural gas, and a convenient source of clean energy. The gas is easily collected and stored for lighting, cooking and other household uses. After bacteria digest the dung, the by-product is a rich organic fertilizer, sometimes called slurry, or bioslurry. That fertilizer is more effective than raw dung, with important benefits for hands-on farmers. For instance, it doesn’t smell bad, and almost all the pathogens and weed seeds have been destroyed. There is no downside. No waste. No poisonous residues or batteries. Few moving parts. Gobar Gas is an astonishingly elegant tap into “the circle of life” which environmentalists, economists, development people and humanitarians can all admire.

Comments
My son (an engineer as well as an artillery officer) says he sees all kinds of possibilities if some of the villages in the river valleys could install some of these fuel producing systems.
You know the Marines. . . they'll improvise and adapt if given the OK from the higherups.
Headed over to the PayPal site to send you a few.
Some farms here in upstate New York are putting in methane collection systems. To hear them talk about it, it sounds like some really new idea. Kinda funny really.
Some of the high and mighty who allocate money to State, DoD and the NGOs need to read this. Airborne.
love this story; thank you for your perseverance!
Haiti has effectively deforested itself, I wonder if this is something for Haiti?
I pray God will continue to protect you in your travels.
Also, I love this line from the "Jobs" section of the SNV website:
"Forget about the young volunteers that used to be posted by SNV in the distant past. SNV today solely works with highly specialised and experienced professionals, who are willing to make long-term commitments to this career choice."
Keep up the great works Michael.
You mention that this is, "...an abridged version of a far more detailed dispatch..."
Could you post the longer one?

Is there any talk about using this idea in Afghanistan? Besides contacting my local representatives and politicians who I believe would be interested in this idea, what can we do to kick start it there? This could be huge.
Thanks
Arik
A central point that could produce this gas for a village or town?
Maybe set an example?!?
Great article and pictures!! Keep up the good work!
The same is true of this technology. The PH of the mix determines the output. Too little manure or too much vegetable material upsets the PH and can/will delay or ruin the process.

Great job Michael !
We all need to pray that this can be developed in every country where it is needed.

I am but a Gurkha; poor, marginalized and voiceless. Thank you for speaking something on behalf of us.

If you take a quick look at the border between Haiti and the Dominican Republic on Google Earth, there is literally a line where there are trees on one side, and none on the other. Right now, I am envisioning US troops going house to house and setting these things up. If the Amish can get a few hundred guys together to build a barn in a day, we can round up a company to build a house or village sized gobar gas unit. Taliban monopolies on cell phone tower coverage will have no bearing on the ISAF's Gobar Gas monopoly.
Not cutting edge technology, but it fine bit of kit made locally and robust.

Excellent article
!
I'm a retired USAF SOF operator. Having worked on numerous civil affairs projects, I know you're right on target with the analysis in this article. Your posts are required reading for the joint service special ops ROTC group I'm advising. I know these future warriors and leaders will get the truth from you.
Since retiring in 1997, I have helped form a sustainable agriculture group in upstate New York. We are VERY interested in implementing the gobar gas home units with our members. Could you please offer some tips on source info for manufacturers, suppliers, even plans from local Asian families.
We're eagerly looking for more of your stories on the combat troops, the locals and the background info in OEF.
Blessings!
Golly, I thought that this technology had given away to something else.
Can that slurry be used to build fertilizer bombs against our troops?
The next big hurdle is temperature. The microbes need temperatures consistently higher than 15 deg C to efficiently break down the raw dung (a yearly average of at least 25 deg is preferrable). In Nepal, biogass is generally feasible up to around 3000m altitude, and at higher latitudes the temperature differential brings this max altitude down. In the winter, gas production drops significantly. How many parts of rural Afghanistan are within the appropriate temperature ranges?
Also, a minor point: while laboratory results show that methane yields of 70-80% are possible, the majority of working reactors do not reach this efficiency. Research in the Negev shows average methane values closer to 35-50% for goat dung (less efficient than cow dung), which is still good enough for cooking.
Keep up the excellent work!
Jon
Your points are very important. I did a lot of research on those same topics. Some places in Afghanistan are definitely in the right temperature range -- and there is plenty of water. (Some places.) For instance, Helmand, Kandahar, Nangahar and some other areas seem perfect.
Will go into far more details in the unabridged version of the dispatch.
Great to read that you are working on Gobar Gas. This is very important and it's just kind of humming along in the background.

I'm a farmer now based in Ireland; is there any way I can get either the plans ("Diagram of 'Gobar Gas' installation in Laos"), or one of the kits you showed in the photo, or even both? We've put up our own wind turbine that we sourced from China after much research, also will be installing micro-hydro. Have experience with P.V. out in the desert in the US. Also with Pure Plant Oil production on farm. So we like tinkering with stuff and getting our hands dirty - but all the same, I wouldn't mind getting my hands on one of the kits if I could. Would be a bonus too if we could support any group/company that subsidizes/help s fellow farmers elsewhere.
Thanks for your time and information.
I googled *urine biogas*, and the first hit (Bangladesh J. Sci. Ind. Res. 41(1-2), 23-32, 2006) claims that using urine as a substitute for water actually increases biogas yields. I would appreciate your comments on this study.
O. O'C.:
Google *biogas plant design*. Somewhere near the top of the list should be the Nepal Biogas Plant Construction Manual.
Thank you so much
Mabbe we wouldn't even need to war in the 'stans' in order to provide us with the strategic lines to our power sources?
imagine...
We need to DESTROY our dependency of the big social/governme ntal functions to survive. Our future lays in the destruction of our "own" governments, who are presently in the business and process of replacing us with more suitable subjects.
And that - as they say - is that.
I am a strong supporter of more decentralizatio n in our infrastructure. It empowers people and produces a system that is more robust that can recover better if it takes a hit, whether natural or man-made.
As ever a great in-depth report and full of lots of relevant detail, but perhaps just a bit too fanciful to suggest there maybe similarities in their developments... ...Nepal is not Muslim.
Just a thought.......
Also, there are already technologies available for exploiting poppy into bio-fuel...it's just that there is no need for it in Afghnistan!
I have posited an article on Methane production and have linked back to this article on your great site. I hope you do not mind that I have used one of your photos from your article, complete with credits:-)

I am speaking "outside my pay-grade", on such matters, but I will, none the less, suggest that the construction of these digester systems, and the manufacture of the stoves and other related paraphernalia, are dependent on some very 20th Century technologies - themselves dependent on abundant (cheap) fossil fuels. The relatively cheap availability of portland cement (concrete), as well as various metals, not to mention much else in the modern world (eg, food), is a modern phenomenon quite directly related to the boom in fossil fuel abundance. One might note the parallel tracks of fossil fuel production and human population over the past two centuries. There awaits, yet, a reckoning with our ballooned human numbers, a reckoning that "technology" of some sort may forestall, but cannot prevent. The raw, wild Earth has managed to maintain sustainable systems for "long periods of time", in human terms, but the human track record - for outsmarting natural systems and limits - isn't so good. The potential reduction of deforestation, and the increase of educational opportunities, among other considerations, is commendable, but the real challenge will come with managing the reduction of our absolute human numbers, so that forests and fauna in the strip-mined (and over-populated) portions of the world can resume their geologic-histor ic roles of self-sustenance . Mythical Adam and Eve arguably did live in a sort of "Garden of Eden", but they threw it over, and went on the road in search of "Pandora's Box". For better and worse, we've been living with the contents of that box for all the millennia since "The Fall". Civilization is only a blip on the planet's face. We are on the inevitable downside of that blip.

I was in Ghazni Afghanistan in 2008-09 with the Texas Agribusiness Development Team as the Micro Power Engineer. One of the alternatives that I investigated was Biogas. As I knew nothing about the subject prior, I did a ton of research. As I did not start this research until about 3 months before my deployment ended, my only output was a research paper with the recommendation to begin experimenting with the concept on our experimental farm. I have no idea if the project went any further...perha ps you can find out. I enjoyed your article!
SNV did improve the project, by setting up a system that allowed other companies to compete with the Gobar Gas Company that was set up by DCS, and by providing subsidy and loan finance.
However, I will use this forum to put on record that most of the ideas that made the Gobar Gas project work came from Sanfred Ruohoniemi.
Off to paypal
Best for now

Then the utility can run electricity, the people can make monthly payments, of course. And if they have electricity they want to buy a TV, they can make monthly payments of course. Soon living just like an American!
Start up companies will be subsidized but not to the excessive amounts of recent solar failures. All part of the 'revenge' outlook for the foreseeable future...

Pretty crappy solution if you ask me but better than wood in that very long run.
