Deforestation in Columbia has fallen 36% in a year

Rainforest is essential if we are to combat climate change. Therefore every fall in deforestation is fantastic news.

Of course, it should be noticed, that this is still a loss of 792 square km of forest from the year before – we need to reach zero forest lost per year, but every step towards this target is positive.

The former higher rate of deforestation has its roots in the chaos caused by the fall of the largest guerrilla group the Farc, which disbanded in 2017.

Columbia is considered the second most biodiverse, is fighting to be a leader in the fight against climate change. Of course, this needs to continue to fall, and indeed have large areas replanted, if we are to avoid much of the climate change, but one step at a time

Might the solution to deforestation be education? probably not everywhere, but clearly here in Sumatra

Camp Granit – Sumatran rainforest (not the same place)

There is a variety of different causes for deforestation. However, the majority of the work is usually done by individuals – often for subsistence farming, though often the land is only fertile for a short period of time, requiring more rainforest to be cut down.

However, if people on the ground know that cutting down the rainforest will make life worse, then they will not do it.

Efron Simanjuntak (click here to see a photo in a new window) was once a successful logger (illegally) in Sumatra. In 2017 he was caught, and in 2018 he was imprisoned for 2 years. In these two years, he had a lot of time to think, and realized the damage that he was doing.

Currently, in the Amazon rainforest, 5 times more carbon is released from degradation than from deforestation – and still what remains continues to burn

A study, using detailed 3d surveys, found that road building, and other degradation is causing 5 times as much carbon to be released into the air, than deforestation of the Amazon.

From road building, to selective logging, fires and natural disasters, all these activities are combining to having a greater impact on carbon stocks in the Brazillian Amazon than deforestation. This huge discrepancy is not taken into account by the numbers.

This is also a problem to the world, as this carbon is being radically underestimated, which means that large quantities of our remaining carbon budget are being used up. This new survey used lidar, which gives a more accurate idea of what is left in terms of forest cover.

With the addition of lidar sensors on the ISS, it is possible to scan the worlds forests more often – and given the ISS regular passing over 90% of the earths surface (in each 24 period – as while it orbits on a set path, the earth turns below it) this can be a good tool to keep an eye on the forests of the earth.

Another confirmation (as if it was needed) has been supplied by this study, showing that Indigenous territories and conservation units are both more efficient ways to protect the forest. These cover only 47.5% of the land, but contain just 9.1% of the forest clearing 2.6% of the logging and 9.6% of the fires.

Talking of fires

Fires continue to burn in the Amazon, with over 13,400 having been recorded in 2024. President Lula has called for general mobilization and Brazil has pledged to end deforestation by 2030. This is higher than during Bolsonaro’s time in office, though current cause is a drought, not human mismanagement.

Climate change is causing an increasing change in weather patterns, and reduced rainfall is changing the forests behaviour ( it should be noted, that the forest produces a not -insignificant portion of its rainfallm

Amazon rainforest droughts linked to climate change

Why is this a problem? Well there are several issues that should concern everyone. The natural end of the line, is for the complete loss of the Amazon rainforest. There is much fear that it may be another tipping point, and that therefore, once the rainforest starts failing, it would accelerate the loss of the rest.

Half of plantations in Indonesia’s palm oil heartland are illegal

I wrote in February about how an assessment had found that 20% of palm oil plantations were illegal (to read click here). This latest assessment suggests that in its heartland, half are illegal. Riau province is this heartland. Illegal plantations within this area cover an area almost as large as Hawai, and hosts more than half of the illegal plantations in the whole of Indonesia.

These illegal plantations are also not all owned by small players, with some of the biggest names in palm oil on the list. The government is suggesting 3 years to get retrospective permission.

The problem with this, is that it is essentially permission by the back door. If companies know that they will eventually get permission, there is a high incentive to break the law.

Furthermore, if these areas were designated for coservation, we need to find areas of similar importance to replace them
