Carbon mitigation potential of different forest ecosystems under climate change and various managements in italy

Abstract

This study reviews carbon stocks and carbon dynamics in different types of forest land in Italy: ordinary managed forests, forest plantations, old growth forests, and trees outside forests. Forest management, combined with global environmental changes, increases the capacity of carbon uptake of ordinary managed forests. Forest plantations, particularly the ones subject to short‐rotation forestry systems, potentially have high soil carbon accumulation, especially in agricultural lands. Old growth forests, recently discovered as a carbon sink, cover a significant surface area in Italy. Moreover, the trees outside forests may represent a sensible carbon stock, especially in the context of urban environments. Our study points out the management actions that can be implemented in Italy to increase the carbon stocks of different forest ecosystems, such as increasing the mean annual increment in managed forests, enhancement of the national network of old growth forests, and expansion of forest plantations in suitable areas. These aspects have important implications after the recent recognition of the Land Use, Land Use Change and Forestry sector in the EU target within the 2030 Climate and Energy Policy Framework.
