Eucalyptus
plantations as biomass fuel: substituting evil for wrong
More and more the rush to use biomass
as an alternative source of energy allegedly to reduce CO2 emissions
is concealing the unsustainable consumption pattern that underlies
global warming and climate change.
Reduccionist approaches focus on solutions
which create even greater harm. That is the case of a major European
project which has enthusiastically identified industrial-scale
eucalyptus plantations as an answer for so said less polluting
steel manufacturing processes.
Led by the main European steelmakers,
the European Ultra Low CO2 Steelmaking (ULCOS) project involves
the French Agricultural Research Centre for International Development
(CIRAD) and its central theme is to replace fossil fuels with
biomass, notably from monoculture tree plantations in the tropics.
Apart from developing more efficient
processes for converting biomass into charcoal, the project addresses
the biomass availability from eucalyptus plantations, and CIRAD
conducts research on the availability of such woody biomass. It
has identified “good candidates” for biomass production --which
means where to establish industrial-scale eucalyptus plantations.
The ‘candidates’ chosen to host such
plantations are: Brazil, which CIRAD considers could have 46 million
hectares available in 2050, and several central African countries
-- Congo (South), the Democratic Republic of Congo (West), Angola
(North and East), Zambia (West), Tanzania (West and South), Mozambique
(North) and the Central African Republic (West and Centre)-- with
46 million hectares.
This amounts to increase the area of
monoculture tree plantations, with the ensuing severe impacts
on soil, water, biodiversity and livelihoods. Even worse, the
establishment of such large-scale plantations would destroy existing
ecosystems –as is already happening- such as grasslands, forests,
peat lands, wetlands, which provide livelihoods to local populations.
Such destruction implies the release of enormous amounts of greenhouse
gases, which challenge the basis of those kinds of projects.
Replacing the major problem of burning
huge amounts of fossil fuels with further problems like the encroachment
of highly diverse ecosystems and the depletion of soil and water
by fast growing eucalyptus will only make matters worse. Meanwhile,
the climate keeps changing.
