<BLOCKQUOTE style="BORDER-LEFT: blue 2px solid; PADDING-LEFT: 5px; MARGIN-LEFT: 5px"><FONT style="BACKGROUND-COLOR: transparent" color=#000000 size=2 face=Arial>Stovers:<BR><BR>I found the following quote on a FAO
publication<BR>(http://www.fao.org/docrep/005/y4450e/y4450e10.htm), and
I<BR>wonder if this is a correct statement responding to the question
:<BR><BR>"Must charcoal be a cause for concern?<BR><BR>The shift from fuelwood
to charcoal, even if it lasts only a few<BR>decades, could have major
ecological consequences if it is not kept<BR>under control. However, since
charcoal stoves are more efficient than<BR>wood stoves, the ratio of primary
energy to usable energy is almost<BR>the same as with fuelwood. Thus with
adequate supervision, management<BR>and support, the shift does not need to
disrupt present levels of<BR>resource use."<BR><BR>What do you think?
Can at the end, with actual stoves and charcoaling<BR>efficiencies, be
the wood consumption the same?<BR><BR>Rogerio<BR><BR></FONT></BLOCKQUOTE>

<DIV>DD If one produces the charcoal in a charcoal making stove than the fuel
can be used twice to produce heat. </DIV>
