Deforestation: Tropical tree losses persist at high levels

Around 12 million hectares of forest in the world's tropical regions were lost in 2018, equivalent to 30 football fields per minute.

While this represents a decline on 2016 and 2017, it is still the fourth highest rate of loss since records began in 2001.

Of particular concern is the continued destruction of what are termed primary forests.

An area of these older, untouched trees the size of Belgium was lost in 2018.

Why is this new data important?

The Global Forest Watch report paints a complex picture of what's going on in the heavily forested tropical regions of the world that range from the Amazon in South America, through West and Central Africa to Indonesia.

The forests of the Amazon basin are home to an estimated 20 million people. Among them are dozens of tribes living in voluntary isolation.

As well as providing food and shelter, the trees in these regions are important to the world as stores of carbon dioxide and play a key role in regulating global climate change.

Millions of hectares of these forests have been lost in recent decades, having been cleared by commercial or agricultural interests.

The data from 2018 shows a drop from the previous two years, which saw a huge amount of trees lost to fire.

However, those involved in the research say this good news is somewhat qualified.

Countries with the greatest primary forest loss in 2018

"It's really tempting to celebrate a second year of decline since peak tree-cover loss in 2016," said Frances Seymour from the World Resources Institute, who run Global Forest Watch.

"But if you look back over the last 18 years, it is clear that the overall trend is still upwards. We are nowhere near winning this battle."

What are primary forests and why do they matter?

Primary forests are those that exist in their original condition and are virtually untouched by humans.

Sometimes referred to as old growth forests, these areas can harbour trees that are hundreds, even thousands, of years old.

They are critical to sustaining biodiversity, and are home to animals including jaguars, tigers, orang-utans and mountain gorillas.

These old forests really matter as stores of carbon dioxide, which is why the loss of 3.6 million hectares in 2018 is concerning.

"For every hectare of forest loss, we are one step closer to the scary scenarios of runaway climate change," said Frances Seymour.

Is this all just about the Amazon?

Unfortunately not!

Back in 2002, Brazil and Indonesia made up 71% of tropical primary forest loss. In 2018, these two countries accounted for 46%.

The Democratic Republic of Congo is now the country with the second largest losses by area, while countries like Colombia, Bolivia and Peru all saw increases in primary forest disappearance.

Colombia continued the dramatic rise first seen in 2016. It's been linked to the peace process in the country where areas of the Amazon once held by FARC guerrillas have now been opened up to development.

Madagascar lost 2% of its entire primary forest in 2018. That was more than any other tropical country.

The disappearance of these trees is causing "heartbreaking losses in real places", said Frances Seymour.

"All too often the loss of an area of forest is also associated with a funeral because every year hundreds of people are murdered when they try to stop the miners, loggers, ranchers and other commercial interests from appropriating their forest wealth – the moral imperative to act on these numbers is unquestionable and urgent."

What is going on in West Africa?

Countries including Ghana and Cote d'Ivoire showed the highest rise in percentage terms in losses of primary forest. Ghana saw a whopping 60% increase while Cote d'Ivoire saw a 26% rise.

Most of this increase, particularly in Ghana, is likely to be due to small-scale gold mining. There has also been an expansion of cocoa farming.

Campaigners are concerned that the rise comes despite pledges made in 2017 by leading cocoa and chocolate companies to end deforestation within their supply chRead More – Source
