Halfway through moratorium, climate-change
goal is still out of reach.
Stopping
deforestation and reducing atmospheric carbon emissions by keeping carbon
locked up in trees takes more than just banning forest clearance, as Indonesia
is finding out.
The country
— home to the world’s third-largest tropical forest and some of the highest
carbon emissions from deforestation — is halfway through a two-year moratorium
on the issuing of new permits to clear forests on 65 million hectares of land.
The initiative is part of a US$1-billion deal with Norway to protect the South
East Asian nation’s forest and cut the country's greenhouse-gas emissions by
26% by 2020. It puts the Indonesia’s efforts to conserve its forests a step
ahead of those taken by most other heavily forested nations.
But as
increasingly accurate forest maps and data on clearance permits become
available, it is growing clear that the moratorium is having little effect on
deforestation rates and carbon emissions — and secures a smaller area of forest
than was thought.
However,
the Indonesian government has confirmed its commitment to its climate-change
pledge by extending the protected area and stripping a palm-oil firm of a
permit to develop carbon-rich peatland.
“No
other country has done anything like this,” says Daniel Murdiyarso, a
climate-change scientist at the Center for International Forestry Research
(CIFOR), based in Bogor, Indonesia.
The
government’s transparency in providing accurate data on forested areas and
clearance permits is an “achievement and great step forward”, says Murdiyarso,
although that in itself won’t do much to reduce carbon emissions.
Norway’s
environment minister, Bård Vegar Solhjell, acknowledges the limitations of the
moratorium. “We know that the moratorium itself is not sufficient to reach the
climate mitigation pledged or to stop deforestation in the speed necessary,” he
said in a statement last week.
Less than ideal
Progress
is slow in part because the clearance-permit ban is not as radical as it at
first seemed. An analysis from CIFOR, published last October, found that 42.5
million hectares of forest covered by the moratorium are already protected
under Indonesian law, with only 22.5 million hectares receiving extra
protection.
An
updated version of Indonesia’s forest map, published last week, shows that the
government has included a further 862,000 hectares of forest under the ban, but
it has also excluded another 482,000 hectares, so the net additional protected
forest is 380,000 hectares. It is not yet clear what kinds of forest are
covered by the changes.
That
could be the key to making the moratorium successful, because some types of
forest have greater conservation value and carbon-storage potential than
others, says William Laurance, a forest-conservation scientist at James Cook
University in Cairns, Australia.
Laurance
and his colleagues studied the Indonesian forest maps and found that the
moratorium excludes roughly 46 million hectares of vulnerable rainforest known
as mixed-dipterocarp forest. The findings were published online in Conservation
Letters1 in April.
“The
mixed-dipterocarp forests of Indonesia are among the most biologically
important and imperilled real estate on earth,” Laurance told Nature.
These
forests were left out of the moratorium because they had previously been logged
and so were thought to lack conservation value, says Laurance. But what remains
is being rapidly cleared for palm-oil or wood-pulp plantations or is being
re-logged, and so is in imminent danger, he adds.
Every little helps
Laurance
does commend the Indonesian government for protecting 11.5 million hectares of
forests growing on carbon-rich peatland. If deforested, these areas could
release up to eight times more carbon into the atmosphere than would dryland forests
growing on mineral soil.
The
Indonesian government’s priority for the second and final year of the ban must
be to continue to improve forest monitoring and governance of forest-clearance
permits, says Nigel Sizer, director of the Global Forest Initiative at the
World Resources Institute, an environmental think tank based in Washington DC.
“This will determine if Indonesia can stop deforestation,” he says.
Sizer
welcomed the government’s move to retract a permit awarded to Kallista Alam, an
Indonesian palm-oil company, to develop an area of peatland in the western
province of Aceh. The permit had been awarded after the ban was announced.
“The
moratorium is imperfect but it has made some progress. There’s no option but to
press ahead and hope for the best,” agrees Laurance. “Indonesia is like some of
the mega-banks in the modern financial world. It’s too big to fail.”
