Forest fires destroying vital buffer against climate change

Forest fires destroying vital buffer against climate change
With fierce blazes raging
in jungles from the Amazon to Indonesia, concerns are mounting about the
impact as rainforests play a vital role in protecting the planet against
global warming.

The latest serious outbreak is in Indonesia, where smog-belching fires
started to clear land for agriculture are burning out of control, blanketing
the region in toxic smog.

Why are rainforests important in fight against global warming?

Mankind’s reliance on fossil fuels usually receives much of the blame for
climate change but scientists say that deforestation has also played a big

Forests are natural buffers against climate change, as they suck greenhouse
gas carbon dioxide out of the atmosphere.

But forests worldwide have been logged on an industrial-scale over the
decades for timber and to make way for agricultural plantations.

Burning of large expanses of trees also releases huge amounts of carbon

At the peak of Indonesia’s 2015 forest fires — the worst in the country
for two decades — the country spewed more greenhouse gases into the
atmosphere each day than all US economic activity for the same period,
according to environmental watchdog the World Resources Institute (WRI).

How much of Indonesia’s rainforests have been destroyed?

Greenpeace estimates that in the past 50 years, more than 74 million
hectares (182 million acres) of Indonesia’s biodiverse rainforests — an area
twice the size of Germany — have been chopped down, degraded or burned.

They have often been destroyed to make way for plantations for the
lucrative palm oil and pulpwood industries, particularly on Sumatra and
Borneo islands, with fires often started illegally to clear land.

Indonesia suffers forest fires annually but this year’s appear to be the
worst since 2015. The country’s disaster agency estimates that from January
to August, about 328,000 hectares (810,000 acres) of land was burned.

The country has however managed to slow the rate of deforestation in recent

Why are they burning and can it be stopped?

Farmers and plantation owners are usually blamed for starting the fires as
a quick and cheap way to clear land.

Major companies typically deny starting blazes and instead point to small-
scale farmers and villagers. The most serious fires occur in peatlands, which
are highly combustible when drained of water to be converted into

The situation this year has been worsened by drier weather in Indonesia.
Authorities have deployed thousands of security forces to battle the blazes
but most believe only the start of the rainy season — usually in October —
will douse them.

After the 2015 fires, President Joko Widodo’s government took steps to
prevent a repeat of the catastrophe.

Authorities have tried to improve law enforcement to catch those
responsible for illegal burning and set up an agency to restore degraded
peatlands, which should make them less vulnerable to being set ablaze.

Arief Wijaya, from the Indonesia branch of WRI, told AFP that improving the
lot of poor communities who have long turned to burning land for agriculture
is also important.

“If you really want to prevent the fires from happening, you need to
improve local livelihoods,” he said.

How does this compare to the fires in the Amazon?

The fires in Indonesia are far smaller than those in the Amazon, the
world’s biggest rainforest.

Wildfires in Bolivia have torched two million hectares (4.9 million acres)
of forest and grassland since August while in Brazil 88,816 fires were
recorded from January to the end of August, over half of them in the

What will be the impacts for global warming if forests keep burning?

Increasing outbreaks of forest fires worldwide creates more greenhouse gas
emissions and makes it harder to limit temperature rises, experts say.

The landmark Paris climate deal requires all countries to devise plans to
keep temperature increases to “well below” two degrees Celsius (3.6 degrees
Fahrenheit) above pre-industrial levels.

It calls for rises to be limited to within a safer limit of 1.5C — but the
UN’s Intergovernmental Panel for Climate Change warned last year that at
current levels of greenhouse gas emissions, we could pass this marker as
early as 2030.

“If (forest fires) continue, the dream to limit global temperature rises to
1.5 degrees will remain just a dream,” said WRI’s Wijaya.

“We will fail.”
