[Stoves] report with disappointing results from cleaner cookstoves

[Dr. Dieter Seifert]

Dear Crispin,

in Africa a „billion dollar business“ with charcoal is established and 
there it is _not_ easy to supply it sustainably with traditional 
processes, even with improved charcoal stoves. The continent will lose 
its trees in the next three decades if business as usual continues - in 
many regions earlier, see e.g. New York Times article: Africa’s Charcoal 
Economy Is Cooking. The Trees Are Paying”.

Even if new trees are planted for a tree, cut down for charcoal 
production (traditionally 6 to 12 tons of wood for 1 ton of charcoal), 
it will take about 20 to 50 years until the replacement will be 
effective – if at all. You may find more information and proposals in 
the internet e.g. on my paper “Traditional Charcoal in Africa and Need 
for African Institutes ARTIS”.

Kind regards,
Dieter

The CDM funding is only available when the fuel supply is being cut 'unsustainably', as defined. There is no (official) interest in saving fuel in places with an excessive supply of it.

That places the user and their perception front and centre, instead of an outsider pushing the agenda they happen to have funding for. Darfur is a good example. Some families ended up with half a dozen different 'improved stoves' or more.
