Three decades of urban forestry in China

Urban forestry has been formally recognized as a codified academic discipline in China’s higher education since 1992. This short communication attempts to revisit the emergence and development of urban forestry in China over the last three decades. Despite the traditional disciplinary division existing between forestry (which focuses on forested landscapes in non-urbanized regions) and landscape architecture (which concerns about individual and collective plants in urbanized environments), urban forestry offers an interdisciplinary convergence point, drawing upon disciplinarily-specific understanding and expertise of both forestry and landscape architecture, that supersedes the urban-rural distinction and could be translated into flexible, integrative, and transdisciplinary approaches for the effective governance of urban and peri-urban forests. With the enrichment of empirical evidence from China’s unique socioeconomic context and the theoretical advancement of urban forestry, innovative practical initiatives like “National Forest City” successfully transform urban forestry knowledge into on-the-ground practices. While China’s unprecedented urbanization has been accompanied by social and environmental problems calling for solutions wherein urban forestry can contribute, it offers a fertile ground for further advancing the development of urban forestry.
