The network diagram displays multiple colored clusters of interconnected keyword nodes linked by thin curved lines. In the center-right area, a large blue cluster is centered around the prominent node “ecosystem services”, connected to nodes including “choice experiment”, “willingness to pay”, “contingent valuation”, “choice experiments”, “non-market valuation”, “economic valuation”, “payments for environmental ser”, “carbon sequestration”, “renewable energy”, and “benefit transfer”. In the central area, a large purple cluster is centered around “climate change”, connected to nodes including “adaptation”, “well-being”, “air pollution”, “economics”, and “agriculture”. In the left and lower-left areas, a green cluster contains prominent nodes including “sustainability”, “sustainable development”, “ecological footprint”, “environment”, “input-output analysis”, “international trade”, “trade”, “environmental kuznets curve”, “degrowth”, and “ecological economics”. In the lower-right area, a red cluster contains nodes including “land use”, “conservation”, “deforestation”, “environmental policy”, “institutions”, “property rights”, and “transaction costs”. In the upper-right area, smaller yellow and purple nodes include “life satisfaction”, “subjective well-being”, and “invasive species”, connected to nearby clusters. The nodes vary in size, with “ecosystem services”, “climate change”, and “sustainability” appearing among the largest and most connected nodes in the diagram. A “V O S viewer” logo appears in the lower left corner of the image.Co-occurrence analysis
