It’s the Lula effect? Amazon deforestation falls by 34% in six months

,
The numbers, which have not been verified by an independent authority, would mark a turnaround for the Amazon after a particularly bad 2022. Fines and bans are increasing. But fires are also on the rise, having never been so extensive since 2007

Subsoil carbon is particularly vulnerable to climate change

,
International study shows how, at one meter depth, soil gives up more than one-third of its pyrogenic carbon after experiencing a 4°C temperature rise in less than five years

Artificial intelligence challenges deforestation in Brazil

,
The PrevisIA system uses artificial intelligence to rapidly analyze satellite imagery detecting critical variables that can promote deforestation. "Its predictive ability is fantastic," according to its creators

Landowner amnesty has hampered land restoration in the Amazon

,
Since 2012, more than 50 percent of deforestation in the Amazon has occurred in "protected" areas in private hands, a U.S. study has found. Amnesty that excluded managers from restoration obligation was crucial

Mediterranean forests face desertification risk

,
In the past, forests around the Mediterranean Sea partly turned into steppes within a few decades as precipitation rates changed. Today, a German research explains, this scenario could happen again

Habitat diversity helps insects address climate change

,
Insects adapt to global warming with different energy management, a German research has found. Microhabitat diversity, which is crucial, is declining due to land-use changes

Excess nitrogen also impacts soil invertebrates and insects

,
A Dutch meta-analysis of 126 studies conducted worldwide illustrates the consequences of nitrogen accumulation for soil microfauna. Effects vary across species. Climate factor

“Colombian government’s fight against deforestation has been a failure,” NGOs say

,
Operation Artemis, launched by the Colombian government to combat deforestation, has benefited a minimal share of the affected areas, argue NGOs Mongabay and Cuestión Pública. Abuses to indigenous communities have been reported

Canadian researchers start a soil carbon measurement project

,
An annual project in the state of Saskatchewan will collect data on soil carbon occurrence. The goal is to assess soil effects and generate measurable and verifiable emission credits

Insects in decline? “it’s a fault of soil consumption and pollution”

,
A Swiss-German study investigated the main factors behind the constant decline of insects and their biodiversity. Invasive species and intensive agriculture are also of concern. 40% of all species will be at risk of extinction in the coming decades.
