[Stoves] How big is "a tree"

[George Riegg Gambia]

charlie

thanks for the help. there seems to be a wide variety of "standard tree" about - anything from an average of 2.2 tonnes according to a study carried out in guatemala - info from trees water people websire - to 65 kg for a 9 year old eucalyptus in malawi - according to CIDA - thank you richard for that info.

i guess i'm sort of back to square one. nothing better than to go out there and start measuring i guess.

shuva.
ive had a meeting with arjun and hopefully will be able to find the time to travel to the village week after next. looking forward to meet you and to co-operate in the future.

thank you for contacting me. i was aware of the workshop in yundum and have been talking to niall in the past - i know cu are looking into biofuel at the moment as well. it's not easy for me just now to travel upcountry so should you be around the combos i would be very interested to meet up with you. we are a small country and all efforts should be better co-ordinated if possible. my mobile is 770 7090 - i have tried yours but didn't have any network.

thanks all

  It may be that this is still being figured out - this article questions everything (such as which tree species, how big the tree is, where it grows), suggesting that there may presently be no standard.  Stuart Conway (at Trees, Water, People) would be a stover who might know since he deals with credits.

  One definition in Australia is that 5 generic trees planted and left growing for 100 years generates "on average" one carbon credit (one ton of carbon saved).  Assuming that "trees saved" is similar to "new trees planted" you would calculated your processes carbon savings (say in tons/year) and then convert this to this new unit of "trees saved".

  In your proposal it is likely that if you explain your reasoning, paying attention to your local situation (amount of carbon abated by using waste wood chips instead of cutting down local trees for firewood) then that will be sufficient - I can find out nothing internationally definitive because of all the variables.

    Someone??

    We are at the moment developing a project in The Gambia involving compressed paper/sawdust bricks.
    I have a "practical" engineering mind so alot of the scientific details go over my head - I do understand principles, what works and how but the academic education is just not there.
    We will be putting together a funding proposal and at present it seems to be very important internationally to know "how many trees do you safe?"
    I know how much wood i will be "saving" by burning our compressed bricks - i.e wood that does not have to be harvested from still living trees.
    But:
    Does anybody know if there is an international "standard tree"?? Just in simple terms of kg or tons.

    Any input would be greatly appreciated.
    Thanks
