Unmapped roads raise risk to Southeast Asian rainforests — study

  • Researcher Alice Hughes found that roads have penetrated areas previously considered untouched and unreachable by vehicles.
  • An average of 75 percent of roads in five countries were missing from OpenStreetMap (OSM), a mapping platform widely used by researchers and academics.

KUALA LUMPUR: Forests in parts of Southeast Asia face greater threats than previously thought because researchers often rely on data that ignores new roads, which are precursors to deforestation and development, a study shows.
The paper, published this month by the journal Biological Conservation, showed that an average of 75 percent of roads in five countries were missing from OpenStreetMap (OSM), a mapping platform widely used by researchers and academics.
“Large-scale forest clearance is preceded by the growth of road networks, which provide a stark warning for the region’s future,” the study said.
Author Alice Hughes, a researcher at the Chinese Academy of Sciences in Beijing, studied a total of 277,281 square kilometers by analyzing satellite images and maps showing forest loss and coverage, as well as agriculture concessions.
She found that roads have penetrated areas previously considered untouched and unreachable by vehicles.
“We are deluding ourselves that we still have large tracts of inaccessible, pristine forest, when the reality is highly-fragmented, very accessible forests,” Hughs said on Friday.
Her research examined road networks in parts of Malaysia, Indonesia, Brunei, Papua New Guinea and the Solomon Islands.
“In some parts of the region, up to 99 percent of roads on those global maps, which are used as the basis for a huge amount of further analysis, are not included,” she told the Thomson Reuters Foundation.
Deforestation and development of forests in the area studied have occurred at a rapid pace since 2000, said Hughes, while maps used by researchers do not regularly update their road data.
“Most of the time these roads are just providing access to forests and up to 99 percent of deforestation is within 2.5 km of road,” she said. “They are clearly the access method.”
She added that the region urgently needs better protection and enforcement for its remaining forests.
Indonesia, which is the world’s biggest palm oil producer, introduced a forest clearing moratorium in 2011 to help reduce deforestation.
Hughes said the ban should be expanded beyond just land designated as natural, untouched primary forest to include all high biodiversity forests.
Hughes’ research methodology should be used to determine whether the same patterns exist in other parts of the world, said Christopher Martius, team leader for climate change at the Indonesia-based Center for International Forestry Research.
“It is surprising that nobody ever did that before, and it is shocking that the result shows we grossly underestimated the possible threat to tropical forests from road building,” he said by email.

Hero dog saves Indian family in flood-hit Kerala

  • Kerala, famed for its pristine palm-lined beaches and tea plantations, is battered by the monsoon every year but the rains have been particularly severe this season
  • More than a million foreign tourists visited Kerala last year

NEW DELHI: A family in the flood-ravaged Indian state of Kerala narrowly escaped death after their pet dog woke them up moments before a landslide destroyed their home, local media reported Monday.
Mohanan P. and his family were sleeping at home in the mountainous Idukki district when their pet dog started barking raucously at around 3:00 am, waking the household.
“That’s when we realized something was wrong. I went out to see and we had to just rush out of the house,” Mohanan told Indian news network NDTV.
No sooner had the family rushed out when the landslide plowed down a nearby hill and demolished their home.
The family, dog in tow, have since moved to a government-run relief camp nearby.
Flash floods triggered by the annual monsoon rains have pounded the southern tourist hotspot in the past few days, killing 39 people and leaving 100,000 more homeless so far.
