Re: Rural Develpment Forestry and Agroforestry



Dear Patrick:

I like that, "May the forest be with you".  I did quite a lot of reading about
fuelwood production while I was working on my master's in the 80s.  A good
place to look for readings is in Unasylva, an FAO-sponsored journal devoted to
forestry and forestry-related topics.  Another excellent journal is
Agroforestry Systems.  There are also numerous books on the topic of fuelwood.

A couple of things that struck me while researcing this topic:

1)  I am unconvinced that fuelwood gathering is the culprit in many cases of
deforestation.  Poor agricultural practices (including reserving the best
lands for cash crops and forcing subsistence food production to marginal
sites) seem, to me, to account for the greatest part of the deforestation.
Coupling what traditionally were acceptable practices with increasing
populations seems to spell disaster.

2)  Plantations are the best idea I have ever heard for alleviating the
problems faced by those relying on wood for fuel, however, I notice that many
plantations are of species not always the most suitable for fuelwood (e.g.
eucalyptus or pine) and that they oftentimes are species not native to the
region.  It is true that the needs are critical in many places and that in
such cases any tree or shrub that can produce burnable biomass can and should
be used - for the present.  Nevertheless importing species that are non-native
and which, in many cases, exhibit weedy characteristics can also hasten
environmental degradation as clearly as deforestation and should be used with
caution.

Biological invasions across the globe are coming to our attention more and
more every day and scientists are busy documenting the environmental damage
that many of these invasions cause.  Plantations for fuelwood production
should be promoted - but always the long-range picture in mind.  Will
introduction or dissemination of certain species threaten the landscape one
decade or many decades later?

I am reminded of the story of some good hearted, well intentioned development
person who decided that mesquite trees would be ideal for fuelwood in the
Sahel.  Why not?  It burns beautifully, it fixes atmospheric nitrogen, and
best of all, it is drought tolerant.  The thing is, mesquite is not drought
tolerant, it is a drought avoider.   That is, it survives in dry areas by
sending down an incredibly long root system -- right down into the water
table!  The result is a lower water table and dried up wells.  This story may
easily have been told about a native plants as well, the point I want to make
is that before we identify and lable species as "ideal" for certain needs,
including fuelwood, we should carefully weigh all of that species
characteristics including its potential environmental impacts.
