Scientific trends and structural dynamics of ecosystem-service valuation research in agroforestry systems: a bibliometric analysis
摘要
The ecosystem-service valuation in agroforestry contributes to climate resilience and sustainable land use practices. However, the research is still fragmented across disciplines and regions. This bibliometric study systematically examined 1020 peer-reviewed articles indexed in the Scopus database between 2000 and 2024 to comprehensively map global research pathways, thematic patterns and collaboration patterns in the area of ecosystem-service valuation in agroforestry systems. Through Bibliometrix and VOSviewer, we observed an annual growth rate of 23.85%, with an overall number of 31 citations per article. The publications are becoming more global: the developed economies, especially the US (410), Germany (294), and France (282), dominate the output, yet emerging economies, including Brazil (247), India (164), and Indonesia (147), are gaining momentum. The major journals are Agroforestry Systems (128) and Agriculture, Ecosystems and Environment (67). Keywords and network analysis show two dominant themes such as ecological management cluster, including agroforestry, carbon, climate, sustainability, and a conservation-policy cluster, including forest, agriculture, and environmental protection. Trending topics have shifted from regional agroecology to carbon sequestration, biodiversity, and ecosystem-service valuations aligned with Sustainable Development Goals (SDGs). The results suggest a transition towards valuation approaches that integrate ecological, economic, and social dimensions. This synthesis indicates that valuation studies across regions and scales provide insights to support agroforestry practices for climate change mitigation and biodiversity conservation.
