Biofuels: Carbon dioxide oozes from damaged peatlands
in Indonesia
25-11-07
Viewed from the air, the vast, cool forests of the Kampar peninsula on
Indonesia's Sumatra island are a world away from China's belching factories
or America's clogged freeways. But appearances can be deceptive.
Most of this 400,000 hectare peninsula is peatland: dense, swampy forest
that, when healthy, efficiently soaks up greenhouse gases from the world's
worst polluters. When drained, cleared or burned, however, this wilderness
transforms into one of the worst climate vandals, releasing six to nine
times the amount of carbon stored in regular equatorial forests.
Swamps have not traditionally held the same ecological sex-appeal as, say,
doe-eyed wildlife. But as nations prepare for a major global conference on
climate change in Indonesia in December, the world's focus is changing.
The Dec. 3 to Dec. 14 UN summit on the resort island of Bali will see
international delegates thrash out a framework for negotiations on a global
regime to combat climate change when the current phase of the Kyoto Protocol
ends in 2012. A figure from the Indonesia-based Centre for International
Forestry Research puts deforestation at around 25 % of all man-made carbon
dioxide emissions.
Avoiding emissions from deforestation has so far been left out of the Kyoto
Protocol on climate change, which focuses instead on reducing emissions from
sources such as industry and transport. Widespread deforestation has made
Indonesia the third largest emitter of carbon in the world, the contribution
coming most dramatically in the form of near-annual forest fires on islands
such as Sumatra and Borneo.
The fires, which send choking smoke as far as Singapore and Malaysia, are
for the most part caused by the clearing of peatlands. And the destruction
of Indonesia's peatlands accounts for 4 % of total global greenhouse gas
emissions, according to Greenpeace.
Peatlands are not just a threat when they are burning. A flight over Kampar
reveals scars of cleared land gouged from the forest, linked with canals
built to transport legal and illegal logs to inland mills. Much of the
carbon released from peatland swamps is the result of draining so the land,
or the logs, can be used, says Jonotoro, a peatlands expert at the forestry
ministry and an independent consultant. As the water level drops, more and
more of the stock of carbon is released into the atmosphere. In clear-cut
areas, the temperature can rise dramatically in the dry months between July
and September to around 70 degrees Celsius, up from a usual cool average of
28 degrees Celsius.
"If the peat is already dry, it's impossible to make it wet," Jonotoro said.
Peatland is made up of a waterlogged store of semi-decomposed vegetation,
which squelches underfoot. The deeper the peatland -- it can stretch to a
depth of more than 15 m -- the more carbon it holds. If set on fire, dry
peatland can burn for weeks -- the fire can be extinguished on the surface,
only to continue burning underground and reappear the next day.
In Indonesia, the main driver for the destruction of peatlands is the
world's appetite for wood, pulp and palm oil. The best place for plantations
is dry land, but as the rush for Indonesia's last wildernesses continues to
turn much of the countryside into a landscape of industrial uniformity, any
land will do.
At the western end of Kampar sits Pangkalan Kerinci, home of a massive pulp
and paper mill belonging to Asia Pacific Resources International Ltd.
(APRIL). The mill -- and the manicured company town that surrounds it -- is
the nerve centre of a sprawling acacia plantation, much of which is on
peatland.
APRIL is keen to boost its environmental credentials, running a tagging
system to prevent illegal logging. Two of its security guards were killed in
a 2002 confrontation with illegal loggers. Still, seven of APRIL's partner
companies are under investigation for illegally cutting forests.
A cornerstone of APRIL's green efforts is water management in its peatland
plantations. At its nearby Pelalawan plantation, a 1,100 km network of
canals regulates water levels over 100,000 hectares of planted forest.
The goal of the management is to reduce emissions from the peatland beneath,
explained Jouko Virta, head of APRIL's global fibre supply. By keeping the
water table at the highest level tolerated by the plantation trees, Virta
says carbon dioxide emissions from the peatland can be reduced by 80 %. The
company is now pursuing an audacious plan to push into Kampar, converting
more than 100,000 hectares around the peninsula's perimeter into more
plantations, while leaving the centre untouched.
APRIL says the move will reduce carbon emissions, since much of this
perimeter is already heavily degraded, either by illegal loggers or old
concessionaires. By installing their own plantations and managing them
responsibly, they believe they will keep illegal loggers from penetrating
further inland.
"National parks are the happiest hunting grounds for illegal loggers, and
the only way you can protect them is by building barriers," Virta said.
WWF reserved judgment on APRIL's plan, saying they needed to see evidence
that the Kampar ring is really as degraded as the company says, and that
emissions can actually be reined in as much as they say.
"I think we need to see the scientific analysis," said Nazir Foead, WWF's
policy and corporate engagement director, adding that the organization was
aiming to complete its own analysis by the Bali meeting in December.
Consultant Jonotoro is unconvinced by APRIL's optimism and said acacia
plantations will never be a success on Kampar's nutrient-poor peatland.
"The main point of why they chose this area is because they need natural
timber, big hardwood timber" for their mills, he said, referring to their
legal practice of felling and processing the trees from their concessions
before planting.
