In Australia’s logged forests natural regeneration is not enough

,
In southwestern forests, 19% of cleared areas have not experienced natural regeneration. Poor management practices and climate change are determinants
In U.S. Sierra Nevada forests (photo), the combination of deadwood harvesting and thinning significantly reduces the risks of severe wildfire by lowering carbon emissions.

Ancestral practices reduce forest fire risk

,
A study in the US unveils the potential of traditional methods of indigenous peoples: selective harvesting and thinning can prevent fires while reducing emissions
Around the Chernobyl “Exclusion zone” (photo) extends the so-called “Compulsory relocation zone,” which has never been fully abandoned. Thousands of people live in the area but no official investment or land use is allowed.

Low-contamination soils near Chernobyl could now be cultivated, study claims

,
Research involving British and Ukrainian researchers hypothesizes the recovery of large areas of the Chernobyl area where cultivation has been officially banned for nearly 40 years

Overgrazing halt not enough to restore soil in Brazil

,
The study in the Caatinga region in Brazil: stopping grazing is not enough to restore soil health. Additional regenerative practices must be adopted to achieve results

Crisis of forests may double climate mitigation costs

,
This is the hypothesis of researchers at the Potsdam Institute. Current models overestimate the mitigation potential of forests. In this scenario, a delay in response could make the climate goals unattainable
In Southeast Asian regions, agroforestry has led to a 1.08% average reduction in deforestation rate. Photo: pxhere Creative Commons CC0pxhere Creative Commons CC0

Agroforestry has reduced deforestation in Southeast Asia

,
A study has measured the impact of agroforestry in the area: over 250 thousand hectares per year were saved with nearly 59 million tons of CO2 avoided
There are more than 1,500 square kilometers of unmanaged agricultural land in Hawaii still suitable for agroforestry under current climate conditions. Photo: Pixabay Public DomainPixabay Public Domain

Hawaii relies on agroforestry to meet their 2045 climate goals

,
A group of researchers quantified the potential of agroforestry systems on islands. The suitable area is large. Sequestration reaches 125 tons per hectare. A value similar to that of native forests
The massive wildfires of 2023 in Quebec as seen by satellite. During that year, Canada recorded more than 18.4 million hectares of forest burned and about 232,000 people evacuated.

Wildfires in Canada are a serious and worsening problem

,
Wildfires in the country are no longer just a seasonal phenomenon, according to an expert at the University of Ottawa. Drought amplifies the role of all crucial factors

More trees in urban boreal forests are getting killed by climate change

,
Trees are increasingly falling victim to certain phenomena related to global warming such as drought, heat, fire and increased pests, a Finnish research has found. The figures from Helsinki's “Central Park”
In the future, the large northern forests of Canada, Alaska, and Siberia may become denser with trees and more vulnerable to wildfires. Photo: Jasper Hunter Pexels free to usePhoto: Jasper Hunter Pexels free to use

More homogeneity and fires are coming for boreal forests

,
Secondo uno studio della Wageningen University le foreste dell'emisfero settentrionale saranno sempre più simili tra loro a causa dei cambiamenti climatici. In questo modo aumenterà anche il rischio di incendi boschivi
