Forest fires contribute to record global tree cover loss
A SHARP INCREASE IN FOREST FIRES STOKED RECORD LOSSES IN global forest cover equivalent to the area of New Zealand in 2016, according to a report just released by forestry watchdog Global Forest Watch.
The alarming pace of destruction – 51% higher than the prior year with a loss of 29.7 million hectares, according to data from the University of Maryland – was partially due to climate change that has increased the risks and intensity of wildfires by triggering temperature rise and drought in some places.
The 2015-2016 weather phenomenon El Nino, one of the strongest on record, also played a role, having created particularly dry conditions in the tropics.
Many of those tropical areas are not naturally prone to catching fire, but vulnerability increased due to poor management and was exacerbated by El Nino.
Deadly blazes in Brazil and Indonesia were among those contributing to the loss. Last year, deadly blazes have again devastated regions of Portugal as well as California and Canada.
Brazil’s Amazon region lost 9.1 million acres of tree cover – more than three times that of 2015. And Portugal saw some four percent of its forests go up in smoke in 2016, the highest proportion of any other country.
Nearly half of all forests burned in the European Union in 2016 were in Portugal, where fire-prone eucalyptus and pine plantations along with poor soil encouraged the deadly flames. That pattern was repeated this year when deadly fires during June killed dozens of people in central Portugal.
2016 saw one of the largest fires ever recorded in Central Africa, destroying 15,000 hectares of forest in the Republic of Congo.
Last year’s Fort McMurray fire in Canada ravaged more than 607,000 hectares, causing US$8.8 billion in damage.
Deforestation resulting from agriculture, logging and mining also contributed to the losses.
The Global Forest Watch report urges improved fire and forest management, including early warning systems, fire bans during dry seasons and more augmented investment in forest protection and restoration.
