POST, 01 September 2014
In
the major fires that torched Riau in February and March this year, the
province lost 21,000 hectares of forest and overlapping peat cover. The
effects also overlapped.
Nearly
50,000 people suffered respiratory problems due to the March fires.
Businesses,
airports and schools closed, causing Rp 15 trillion (US$1.3 billion) in
material and investment losses.
In
biodiversity terms, forest plants succumbed and wildlife (orangutans, tigers
and gibbons) lost their habitat. In terms of climate change, some 55 percent
or 470 megatons of Indonesia’s annual carbon emissions come from peat fire,
with Riau contributing 27 percent of the emissions.
More
than 90 percent of forest and peat swamp fires in Riau were deliberate,
according to the National Disaster Mitigation Agency (BNPB).
Firms
and small-scale farmers burn peat brush to clear the land so they can grow
oil palm and acacia stands. Intentional peat burning is cheaper, easier and
faster than mechanical land clearing.
Burning
costs Rp 200,000 to Rp 300,000 per hectare whereas the use of land clearing
machinery costs Rp 4-5 million per hectare, according to BNPB data center
chief Sutopo Purwo Nugroho.
Another
reason why forest fires occur is land tenure and land-use disputes. Fires are
used to stake claims in disputes between companies and farmers. Accidental
fires also happen.
Peat
swamps are highly susceptible in the dry season, like now in Riau. Anything
from a carelessly discarded cigarette butt to an unattended, still smoldering
campfire can cause brittle-dry peat to blaze out of control and spread widely
with high winds.
One
means to respond to such fires is the new Global Forest Watch (GFW) Fires
platform, which gives near real-time alerts with the use of high resolution
satellite images.
This
on-line service derives from the Global Forest Watch website that the Washington-based
World Resources Institute (WRI) started in February.
On
July 23, the REDD+ Management Agency (BP REDD+) and WRI in partnership with
the BNPB launched their GFW-Fires platform as part of Indonesia’s Land and
Forest Fires Monitoring System (KMS).
BP
REDD+ chief Heru Prasetyo explained how fires can be detected as they happen
and can be acted upon after alerting local authorities where a hotspot is
located.
He
cited one area in Riau where recent fires had been extinguished after the
satellite-based alert was sounded.
At
BP REDD’s central Jakarta office, Heru spoke on a panel with Deputy Foreign
Minister Dino Patti Djalal (who is board chair of WRI Indonesia), BNPB deputy
head for prevention and preparedness Dody Ruswandi and Forestry
Ministry
director of environmental services for conservation areas and forest
protection Bambang Supriyanto.
They
agreed on investment in prevention, management and law enforcement to curb
present and future land and forest fires.
For
fire management, investment should be spent on infrastructure at the
subvillage (dusun) level. It is in the subvillages where the fire rages. The
subvillage is the ground zero of peat fires. A case in point in Riau is
Bukitlengkung subvillage in Tanjungleban village, Bengkalis district.
Fire
devastated Bukitlengkung on Feb 20. Homes and smallholder plots in the
subvillage were razed and residents were displaced.
But
it took more than a week before large–scale outside help arrived. Volunteers
from the University of Riau were only able to come on March 4.
Other
than the haze, what delayed the aid mission was the poor subvillage road.
The
road from Pekanbaru, the provincial capital, to the district, is excellent
asphalt. The road from the district to the subdistrict level remains good.
The
road from the subdistrict to the village level still has a smooth and hard
asphalt top. But the road from the village level to the subvillage is a dirt
track.
During
wet season, the subvillage road becomes a slippery slush where cars get mired
in the mud. The only way in is by using a four-wheel-drive that is twice as
expensive to rent as a conventional minivan.
Investment
funds should go to convert the dirt road to asphalt to speed up access to the
subvillage where the hotspots are.
Another
investment issue is local mobility. Tanjungleban village has a voluntary fire
brigade with a 15-storey observation tower to monitor the area for hotspots.
The unit has fire-fighting equipment with 50-meter-long hoses and a generator
to pump water from oil palm canals.
The
fire equipment is transported on a two-wheel pushcart. To get a pickup truck
for quicker action, the unit has to contact the subdistrict, if not the district
authorities.
Prevention
is arguably the key track. Effective prevention can mean zero burning.
One
means of prevention is easy, effective and not cost-prohibitive. Where oil
palm stands get scorched in areas that were previously peat swamp, the land
could be rewetted by canal blocking.
The
University of Riau is conducting a canal-blocking experiment on a 2-hectare
plot in Tanjungleban village. The plot is owned by a school teacher whose oil
palm plot was repeatedly destroyed by fire.
He
has now allowed university peat specialists to remoisten the land, which was
originally peat swamp.
Sand
bags block the canal streaming through the plot.
The
water table rises and is absorbed by the soil along the canal banks. The
water nurtures seven types of native forest plants grown on the plot. They
are both eco-friendly and commercially viable. The experiment has been
running for two years.
According
to the Forest Ministry’s Bambang Supriyanto, similar canal blocking is being
done in Central Kalimantan at Sebangau National Park, a peat swamp forest in
Pulang Pisau district.
The
question now is how to build the momentum to make canal blocking a nationwide
drive to rewet erstwhile peat swamps where oil palm stands have been
destroyed by fire.
This
is long-term action, where government and private sector investment can be
piped through. ●
