- Abstract (EN)
- This dissertation studies how different policy mechanisms can align agricultural practices with the increasing societal demand for biodiversity and ecosystem service provision. In light of increasing environmental degradation and ecological uncertainty, agriculture is now expected to deliver not only private goods like food and fiber but also public goods such as climate regulation and biodiversity. Two mechanisms are examined in depth: Payments for Ecosystem Services (PES), a policy-driven approach involving conditional financial incentives for public environmental goods, and Community Supported Agriculture (CSA), a community-based model in which consumers share agricultural risks by committing to producers in advance. In the context of PES, I show that the efficiency of homogeneous payments crucially depends on assumptions about the functional form of social biodiversity benefits and the relation to environmental management. In a systematic review of the literature on payments for biodiversity conservation, we assess to which extent the literature has been imposing such assumptions, and conclude that most studies specify biodiversity objectives such that homogeneous output-based payments would implement efficient biodiversity conservation. Furthermore, PES can also function as an income-stabilizing tool; action-based PES may reduce farmers’ income risk, while performance-based schemes may increase or decrease volatility, depending on the correlation between market and ecological outcomes. CSA operates through shared responsibility. Consumers are found to be willing to engage in risk-sharing, especially when production supports biodiversity. CSA thus offers not only financial stability for farmers but also a pathway to more participatory and sustainable food systems. While PES rely on measurable outcomes and formal contracts, CSA is grounded in relational exchange and social commitment. The dissertation concludes that PES and CSA can be seen as complementary approaches to promote biodiversity in agro-ecosystems. They reflect different institutional logics, but both may contribute to the provision of environmental public goods. A pluralistic governance approach that integrates diverse instruments is essential for managing the complex interplay between ecological, economic, and social dimensions of agriculture.
