What is the value of agrobiodiversity in southern Europe?
研究了欧盟五个地中海国家中，本地和区域尺度的农业生物多样性如何影响农田价值，发现两者存在非线性关系和替代效应，对制定区域化生物多样性政策有参考价值。
Abstract This study explores how agrobiodiversity at both local and regional scales impacts farmland value across five Mediterranean countries in the EU. Previous literature has primarily addressed on-farm biodiversity and its effects on productivity and risk mitigation, yet the potential externalities of agrobiodiversity across neighboring farms remain underexplored. Using a cross-sectional Ricardian approach, we estimate the effects of agrobiodiversity, measured in terms of both crop richness and evenness, on long-term agricultural productivity. Our findings show significant non-linear relationships and substitution effects between local and regional agrobiodiversity, underscoring the need for regionally tailored biodiversity policies.
