As climate objectives are far from being reached under the prevailing policies, more concrete actions should be undertaken, and all possibilities should be exploited. Land-based mitigation potentials are emerging as a cost-effective mitigation prospect. CO2 sequestration is an essential ecosystem service offered by tree cultivations once properly managed. Tree-based mitigation potentials should be identified, evaluated and enriched. The present study aims at developing a framework for assigning an economic value to the climate change mitigation potentials arising from tree cultivation. Such values could enrich the design of coupled agriculture climate policies by offering farmers appropriate incentives to adopt climate objectives.
