Baseline Study of the Socio‐economic Patterns of Charcoal, Wood and Stove use in greater Lusaka, Zambia

Some highlights:

  • Previous stove improvement projects have failed to properly appreciate the central role played by one and two person tinsmith enterprises that produce and sell ordinary mbaulas at very low prices. The tinsmiths of Lusaka constitute a well distributed network of producers and sellers of ordinary mbaulas fabricated from scrap sheet metal who conveniently service all the major markets and townships of the city.
  • In addition to underestimating the multiple competitive advantages of a well distributed network of tinsmiths who fabricate and directly sell a charcoal stove that everybody knows how to operate, previous stove improvement projects failed to appreciate just how poor the bottom 2/3rds of the Lusaka economy really is and how little money low income families are able to save from their daily and weekly income for the purchase of a replacement mbaula when the old one finally breaks down. It is the initial retail price of an improved stove, not how much money it will save a household during the course of a month, that determines whether they are willing and able to spend two, three, four or more times the K4 000 to K6 000 for a 20cm ordinary mbaula. The ordinary mbaula is the industry standard. Every household without access to firewood, no matter how poor, has to pay out at least K4 000 once or twice a year to purchase a replacement mbaula.

Cecil did a good job of discovering the buying patterns in households of at least 3 different income levels, and uncovered that the ordinary (less effecient) Mduala stove has great traction among ordinary lower income members of Lusaka Zambia because the stoves work as expected, and they are inexpensively produced by local stove manufacturers.

He has also shared with us some of the highlights of the report in the attached pdfs.

The Peko Pe TLUD project in Zambia is going well.

Paal describes it best:

" The main principals for our projects I will call it community based participation both for fuel and for stove productions. Utilization of local resources with other words.. The Peko Pe is designed for production by local tinsmith with the tools they might have. They only need a template and a model; they have the knowledge how to make it.

" First of all we discuss the need of changes, and then on the fuel side we start up with registration of alternative biomass for fuel for briquetting, energy forestry for fuel production. We always start with the fuel .to be sure there is sufficient quantities and to an affordable price.

"The charcoal business, which represents about 15 % of the adult population, has to be involved from an early stage of the project. All kind of activities on the household energy sector will in one or another way have an influence of their business, and with biochar we don’t know what will happen, but that is one of the ting we will try to find out. Any how for the charcoal business it is just to change from charcoal to alternative biomass for household energy.

"The energy loss by production of biochar for soil improvement is almost equivalent to the energy needed for the farmer to cook if you include the African way of thinking time is coming not like by us time is running That is a big difference. A household need about 2,7 kg charcoal a day for cooking. Form about 10 kg of dry wood you will get 2,7 kg of charcoal for one day cooking and no biochar. From .10 kg of dry wood you will get 10 kg of woodchips and that will be for 2 ½ day of cooking into a TLUD-ND. and about 2.7 kg of biochar. The pilot project will tell us if this is right or wrong."

" A common Miombo forest in Africa will give about 3 ton wood per ha a year. 3 ton of dry wood will give 800 kg of charcoal. A household of 5 consume 2-3 kg charcoal a day or about 800 kg a year. To produce 3 kg of charcoal you need 10-12 kg of dry fire wood in a common kiln. That will give one day cooking on a charcoal stove, and almost no biochar. 10-12kg dry chopped wood will give 3 days of cooking on a TLUD-ND or another FES and 2.5 kg of biochar
Energy forestry using just the sprouting every year can give up to 10 ton wood per ha a year, easy to cut to appropriate fuel for TLUD-ND’s or other types of FES. By adding some biochar to soil of bad quality 20-30 % increased yields can be obtained, which will give more food, more household energy, more jobs, better economy, better health for women and children and saving the forest. It can probably be as simple as this and is that not some of what we are looking for and need?
We know some changes have to take place on the household energy sector and we have to start somewhere. Why not start with small scale farmers on sandy soil, and from there develop the new household bio-energy strategy for developing countries. Probably also with the charcoal business, they have the whole infrastructure intact and can easy change from charcoal to alternative biomass like chopped wood or pellets from agriculture and forestry related waste.

Chinese Draft Enhancer

Dear Friends

Working on advice brought by Cecil Cook from Lusaka, Peter Coughlin in
Maputo has tried using a short vertical tube (about 400mm) held over the
lighting charcoal to accelerate ignition. This tool is widely used in
Lusaka. It is typically 50mm in diameter and can be made from an piece of
scrap pipe or rolled metal sheet.

Peter reports that people using it have reported faster lighting and a
reduction in emissions during ignition (which is the smoky part of a
charcoal fire).

I tried a similar though larger tube over coal in a bucket and achieved a
dramatic reduction in particulate emissions - certainly more than 90%.

Regards
Crispin

This principle is not only limited to Zambia, it is pretty widely applied by other charcoal users in the region.
Though the most perfect 'chimney' I have got is from China: It came as a standard accessory packed in the carton of the Chinese coal-briquette stove marketed in South Africa under the name of 'Lotti stove'. I think the stove is manfuactured by Shengzhou. So it could be standard chinese practice. The conical shape with the two little air-holes on both sides shortly below the top works much better than a straight tube. We used one at stove camp this year on a two-can TLUD instead of the upper straight can and draft increased considerably. Foto attached, but not sure if it makes it on the list. regards, christa
