Under suitable conditions, deforested land used for agricultural crops or pastures can revert to forest through the assisted or unassisted process of natural regeneration.
These naturally regenerating forests restore biodiversity, provide a wide array of ecosystem goods and services, and help revitalize rural economies and livelihoods.
Based on studies in tropical and temperate forest ecosystems, this new research summarizes cases where natural regeneration is occurring in agricultural landscapes around the world and identifies the socio-ecological factors that favor its development and affect its qualities, outcomes and persistence.
The paper describes how the economic and policy context creates barriers for the development, persistence, and management of naturally regenerating forests, including perverse outcomes of policies intended to enhance protection of native forests.
It concludes with recommendations for specific economic and policy interventions at local, national, and global scales to enhance forest natural regeneration and to promote the sustainable management of regrowth forests on former agricultural land while strengthening rural communities and economies.
