3rd Weihenstephan Future Forum on Agricultural Policy - MO 27.01.2025, 17:00
Subsidy-free agriculture in global markets - conceivable, feasible, desirable?
The European Union's Multiannual Financial Framework provides for agricultural spending of around 379 billion euros for the period 2021-2027, a sum that corresponds to 31% of the total EU budget. No other sector receives similarly high subsidies. And not just in Europe. At the same time, according to leading scientists, modern agriculture is primarily responsible for numerous environmental burdens and the starting point for intensive debates on animal welfare. So are we subsidizing it wrong? More...

RETOUCH Nexus - Resilient water governance under climate change within the WEFE Nexus
With increased water scarcity due to anthropocentric and natural causes, the trade-offs and synergies intrinsic to efficiently allocate water resources to various competing uses have become more polarized. Realizing the importance of an integrated approach in water governance, the RETOUCH Nexus project introduces and promotes the Water-Energy-Food-Ecosystems (WEFE) Nexus as a multi-level and cross-sectoral approach that advocates the EU water economy and, in addition, relies on ecological and social considerations. The overall objective of RETOUCH Nexus is... more
GRASSWORKS - What works and why in grassland restoration in Germany? A multi-region social-ecological assessment and pilot implementation of successful approaches.
GRASSWORKS aims to contribute to the comprehensive and global transformation to reversing species and habitat loss and focus on a greater appreciation of grassland biodiversity and its many ecosystem functions and services. The project focuses on three model regions in North, Central and South Germany, over three ree regions that vary in their economic, social-ecological and socioeconomic contextual conditions. The project is based on the hypothesis that biodiversity restoration success depends on the extent to which projects address the diverse levels of ecological complexity, as well as the social engagement of diverse stakeholders. This is a... more
PONDERFUL- POND Ecosystems for Resilient FUture Landscapes in a changing climate
Ponds and “pondscapes” (networks of ponds) are crucial for biodiversity conservation and their multiple societally beneficial ecosystem services (ES) provide the means to play a crucial role in mitigating and adapting to climate change. However, ponds are largely neglected in water- and nature-related policies and there is insufficient knowledge on how to manage and restore ponds to maximize nature-based solutions (NBS) to increase resilience of ecosystems and society to climate change. The overarching objective of PONDERFUL is ... more

Assessing performance of crop producers from Water-Energy-Food-Environment Nexus perspective: A composite indicator approach
Halytsia, O., Vrachioli, M., Sauer, J. (2024). Science of the Total Environment
Among all the economic sectors, agricultural production is characterised by intensive natural resource use and a noticeable environmental footprint. The assessment of farm performance has been receiving special attention given the increasing scarcity of natural resources and growing environmental concerns. The nexus approach is particularly useful for such types of analysis since it reflects the complex interconnections among the sectors of water, energy, food and environment (WEFE). One way to explicitly place agricultural production within the WEFE Nexus is to develop a composite indicator at the level of decision-maker – farm – that will reflect the interlinkages between agricultural production and the Nexus pillars of water, energy and environment.
Assessing the Environmental Performance of Agricultural Production Using a Parametric Approach: An Appllication for Crop Producers in Ukraine
Halytsia, O., Vrachioli, M., Nivievskyi, O., & Sauer, J. (2024). Eastern European Economics
Agriculture is characterized not only by the production of desirable outputs but also by generating environmental pressures. This article emphasizes the necessity of accounting for “bad” outputs when assessing the performance of agricultural producers. It provides a first attempt to empirically evaluate the environmental performance of crop producers in Ukraine employing farm-level panel data. Our results suggest that the average environmental efficiency for crop producers in Ukraine was 0.84 over the period 2017–2019, meaning a reasonable scope exists for farmers to improve their environmental performance and contribute to meeting carbon reduction targets, as well as help achieve a green postwar economic recovery.
What matters most in determining European farmers' participation in agri-environmental measures? A systemativ review of the quantitative literature
Canessa C., Ait-Sidhoum A., Wunder S., Sauer J. (2024). Land Use Policy
Successful implementation of Europe’s agri-environmental policies faces various obstacles, several of which are closely linked to participation. Effectively increasing adoption of agri-environmental-climate measures (AECM) requires a deeper understanding of farmers’ motives. Various case-study research has targeted ex-post studies but offers context-specific recommendations. Earlier literature reviews provide certain insights, but have not yet clarified how the evidence on adoption can be optimally applied to AECM design. We explore farmer decision-making by synthetizing results from three decades of ex-post empirical studies on AECM adoption in Europe.
