Sweet chestnut (Castanea sativa Mill.) plantations provide vital ecosystem services, including carbon removal from the atmosphere and storage in soil and vegetation. Expanding the revenue streams beyond timber or nut production by monetizing carbon storage can enhance the profitability of these areas. However, current estimates of carbon sequestration in chestnut in Portugal lack differentiation between agroforest and forest systems (coppice or high forest) and fail to account for site quality variations.
Objectives: Considering that the capacity for carbon sequestration is strongly dependent on the cultural system, management and site quality, the objective of this study is to evaluate and compare the carbon storage capacity in young stands of chestnut (up to 24 years old) in forest system (high forest and coppice regime) and agroforestry, considering lower, middle and upper site qualities.
The findings will contribute to understanding the carbon sequestration potential of young sweet chestnut forests and agroforestry plantations, contributing to sustainable land management. Additionally, the results can facilitate the incentive for carbon storage and diversification of income sources for chestnut owners.
