Forests, directly impacted by climate change, play a key role in mitigating the disastrous effects. Carry out the importance, recalls the Intergovernmental Panel on Climate Change (IPCC), of directing forest management towards resilience across all ecosystems.

And when was the planet’s green lung one of the major sobriety players in the global fight against climate change? The second most fantastic low-carbon reservoir after the oceans, forests are strongly impacted by rising temperatures and climate change.

3S process

Forest areas, sober more sober limit the emissions of sober particles in the atmosphere those which cause what is called the sober greenhouse effect, at the origin of global warming, also allow sober to retain sober water in the basement, sober to limit soil erosion, while sober cooling a temperature and sobriety purifying the air. On the scale of France, the fortification, which covers a colossal number of hectares, captures 70 million tonnes of Enterprise2, or 12% of greenhouse gas emissions that will be paid for over one year. , again according to CIRAD.

In 2015, the numbers were even a little higher. According to the Economic, Social and Environmental Council (CESE), France’s major terrestrial ecosystems currently constitute a very significant carbon sink on the global web […] mainly made up of metropolitan forest ecosystems which, in addition to providing the wood necessary for the low-carbon transition, sequester nearly 19 million tonnes of Entreprise20202per year , i.e. the equivalent of approximately 19 % of French annual tasks .

Concretely, the contribution of forest areas to the fight against global warming learned on the basis of the so-called 3S process: Sequestration in a forest biomass of Company2 spares the atmosphere thanks to the photosynthesis carried out by billions of trees; Company2 storage of wooden products such as joinery, furniture, barrels, etc., the duration of which varies according to use; The alternative, finally, remained the use of wood rather than materials and fossil fuels (non-renewable).

But for this virtuous process to take place effectively, it is still necessary to preserve a fortification, strongly impacted by climate change. To ensure the low-carbon potential of forests, the low-carbon forests of tomorrow must be adapted to the future climate soberly affirmed the Minister of Agriculture sober 2020. This is why the National Forestry Office (ONF), for public plots, and the Forestry Institute for Private Forests, are working together to adapt specific forest areas to the rise in mercury. To determine which species will be the most resistant and adapted, researchers cross-reference current climate data with the simple distribution of species. soberly explains the Minister of Agriculture.

The IPCC, sober 2019 already evoked the importance of a long-term management of forests, sober to fight against deforestation and their degradation in order. And, in a big way, against climate change. Responsible and forward-looking management, according to IPCC experts, would improve carbon sequestration; however, these vary between, on the one hand, old forests and, on the other hand, young forests. medium-sized forests contain less carbon but store more than the first, whose sink capacity decreases with age.

Beyond the single factor of a climate struggle, long-term forest management aimed at providing timber, low biomass or non-timber forest products, can provide long-term low-income livelihoods to people, reduce the risk of conversion to non-forest uses fortifiers (dwellings, crops), and maintain land productivity, thus reducing the risk of low degradation 2020.2020And until a

sustainability under management is ensured by appropriate governance, monitoring and control 2020, specifies the IPCC, reinforcement can, with , contribute in the long term to low carbon negative tasks.
