In the Works: Do results-based payments work better for farmer groups?

Project publishes working paper showing that group-based results-based payments significantly outperform individual schemes

FRAMEwork has published a working paper by Rellensmann, Engel, Rommel and Thomas at consortium partner The University of Onsnabruck - examining a fundamental question for biodiversity conservation and sustainable agriculture: are results-based agri-environment payments more effective when designed for farmer groups rather than individuals? Experimental evidence from German farmers directly informs policy design for conservation incentive schemes. The research reveals that group-based approaches lead to substantially higher conservation efforts compared to individual schemes.

Farmer groups demonstrate significantly stronger responses to results-based payment structures than individual farmers, suggesting that collective action enhances the effectiveness of outcome-focused incentives. This finding has immediate relevance for policymakers designing the next generation of conservation support mechanisms.

Experimental Design Testing Real Farmer Behaviour

The experimental research uses rigorous methodology to test these approaches with actual German farmers. Rather than relying on observational data from existing programmes, experimental designs allow researchers to randomly assign farmers to different payment structures and observe resulting behaviour. This eliminates confounding factors and provides causal evidence rather than mere correlation. The German farming context provides particularly valuable insights, as Germany has extensive experience with both agri-environment schemes and farmer cooperative structures. Researchers can therefore draw on established institutions and farmer experience with results-based approaches.

Implications for Conservation Policy Across Europe

The research tests predictions from economic theory about group dynamics, monitoring effects, and payment incentives in a real-world agricultural context. Results may inform not only biodiversity conservation payments but also other collective action schemes including water management, soil conservation, and climate mitigation on farms. The evidence base for what actually works in environmental incentive design remains surprisingly thin, making rigorous experimental research particularly valuable for informing future policy development.

Understanding whether group-based results payments outperform individual schemes has immediate policy implications across the European Union and globally. If groups prove more effective, policymakers should structure conservation payments around cooperative models and invest in farmer group development. Cost-effectiveness matters because conservation budgets are limited and must stretch across millions of hectares of farmland. This working paper will inform ongoing discussions within the EU Common Agricultural Policy reform process and discussions around implementation of biodiversity frameworks.

As farmers face increasing pressure to contribute to environmental targets whilst maintaining economic viability, understanding the most effective incentive structures becomes crucial. The research is particularly timely given the EU's strengthened biodiversity commitments and the role agricultural lands must play in achieving restoration targets.
