(CNN) -- Indonesia have begun cloud-seeding operations over the
island of Sumatra in an attempt to trigger rain to put out fires
creating thick blankets of haze over parts of Sumatra and
neighboring Singapore and Malaysia.
Sutopo Purwo Nugroho, a spokesman for Indonesia's National
Disaster Mitigation Agency (BNPB), said that three Spanish-built
CASA 212-200 aircraft were deployed on Friday to Sumatra. The
rain-inducing operations will continue in three specific areas for
the next 90 days, Sutopo told CNN.
According to the agency, the number of hot spots in South Sumatra
in September has reached 1,241. Hundreds more have been detected
on the island of Kalimantan, which is Indonesia's side of Borneo
island.
South Sumatra has the highest number of hot spots, or areas of
high temperatures that could indicate peat or forest fires. Sutopo
says ground operations to extinguish the fires are also ongoing.
These include spraying, controlled burning, building trenches to
limit the spread of the fire and sluices around the burning peat.
Haze from forest and peat fires has been a perennial problem for
the region, particularly during the dry months. Slash-and-burn
techniques to clear land and droughts have been blamed for the
fires in the past. Using uncontrolled fires to clear land is
illegal, but enforcement has been an issue.
The worst incidence of fires and haze was in 1997 to 1998. The
World Wide Fund for Nature estimates over nearly 100 hectares --
an area three times the size of the Netherlands -- was burned.
The Asian Development Bank put the damages and losses at about US
$9 billion for Indonesia and its neighboring countries. The fires
also had significant impact on Indonesia's wildlife, including
orangutans, tigers and elephants and protected national parks.
