How does the economic risk aversion affect biodiversity?
The present paper analyses the role played by risk aversion in the reconciling of agricultural income and biodiversity. A bio-economic mode which articulates bird community dynamics and representative farmers selecting land uses within an uncertain macro-economic context is developed. It is spatialized and calibrated at a regional scale for France through national databases. The impact of risk aversion is assessed on economic, agricultural and ecological outputs through projections at the 2050 horizon. A high enough aversion proves sufficient to promote global bio-economic performance and multi-functional agriculture. This occurs through a diversification mechanism on regional land-uses. Spatial disparities however suggest that public incentives could be necessary to reinforce the diversification and bio-economic effectiveness.
