The Food and Agriculture Organization (FAO) estimates that the global forest carbon stock will reach 714 gigatons by 2025.
This figure indicates the large amount of carbon compounds stored in forests, including above-ground (live tree trunks, foliage, etc.); below-ground (tree roots, etc.); in the soil (organic soil, mineral soil, peat); deadwood; and litter (organic waste in the form of dry leaves, and various other dried vegetation residues).
According to FAO, carbon stock can fertilize land and support the soil's ability to purify water.
However, if poorly managed, these chemical compounds can be released into the air and cause adverse environmental impacts.
"Poor land management practices cause soil to lose carbon and release greenhouse gases," FAO stated in its "Key Messages - Global Symposium on Soil Organic Carbon".
"Damage to soil carbon reserves due to poor land management will hinder efforts to limit global temperature rise," it continued.
Therefore, FAO encourages the maintenance of carbon stocks in soil, forests, and other ecosystems as a climate change mitigation effort.
In 2025, the largest forest carbon stock will be in Europe, with a volume of 169 gigatons (24% of the total global stock).
Another region whose forests store a lot of carbon is North and Central America, with a weight of 155 gigatons (22%).
