| Charcoal
Usage in Cambodia |
|
|
Fuelwood
and charcoal are the predominant forms of household energy in Cambodia.
In Phnom Penh charcoal is the fuel of choice for 38.8% of households,
and for the country as a whole 119,000 households use charcoal, primarily
for cooking.
In 2004, this will equate to annual charcoal consumption of 65,158
tons of charcoal, or 180 tons per day.And usage will increase as the
number of
households in Phnom Penh increases, reaching over 73,000 tons per
year by 2010. Charcoal is the cheapest source of energy in Cambodia.
The low cost, US$0.10/kg in Phnom Penh, and ready availability of
charcoal encourages users to depend on it as a domestic fuel source.

| Traditional
Charcoal Production |
|
To
produce charcoal in 2004 a total of 434,386 tons of wood, mainly
hardwoods will be consumed. This is equivalent to 724,000 stere
(cubic metres )
According to the report on "Woodfuel Flow Study of Phnom Penh,
Cambodia" (FAO-RWEDP, 1998) the average yield of traditional
charcoal kiln is around 15% or 150 kg of charcoal is obtained from
1 ton of wood.
Based on the information gathered from a number of charcoal producers,
a charcoal kiln can produce 1 ton of charcoal over a 20 day production
cycle. In one year, a charcoal kiln can produce
18 tons. So to fulfil the demand for 50,370 ton of charcoal, there
are an estimated 2,798 traditional charcoal kilns in operation.
Almost all the wood for charcoal production is cut from hardwood
forests with no strategy for replanting. For Cambodian forests to
be preserved a pragmatic alternative to current illegal practices
must be found.

Community
Forestry (CF) is a strategy for sustainable forest management through
the participation of rural people, in which the objectives and benefits
to rural people central.
Throughout Cambodia several organisations have established community
forests covering 55,000 hectares of forest.
In order to maximize the output of useful timber from the community
forests, they require regular pruning, thinning and singling. Based
on an experience obtained from a community forest in Tram Kak, one
hectare of Acacia forest, yields 15 stere (cbm) of wood from first
pruning, thinning and singling. This wood cannot be used for construction
as it is too small in diameter. The only use it has is as fuelwood
or for charcoal production.
If all 55,000 hectares of the community forest can contribute wood
from pruning, thinning and singling, there will be around 825,000
stere of wood every five-years. With a proper management and rotation
system the forests can yield 165,000 stere each year, or 13,750
stere each month for charcoal production.

| Improved
Charcoal Kilns |

|
|
Traditional
charcoal kilns will generate
1 ton of charcoal from 15 stere of wood. Improved charcoal kilns,
such as the Yoshimura kiln or horizontal drum kiln will generate around
1.5 tons of charcoal, a 50% improvement and around 300 litre of wood
vinegar. (Wood vinegar is a substance obtained from the condensation
of the smoke released from charcoal kiln).
To process all the output of the community forests, over 900 charcoal
kilns operating throughout the year will be needed.
By 2010, improved charcoal kilns producing charcoal from community
forests outputs can contribute to the reduction of hardwood forest
consumption by 52,000 stere. |
