The University of Warsaw (UNIWARSAW) plays a pivotal role in the VISIONARY project. Researchers from UNIWARSAW are part of the Department of Microeconomics at the Faculty of Economic Sciences, recognized as one of the top 10% economic research institutions in Europe (as of 2025).

UNIWARSAW conducts research in the fields of sustainable food systems, consumer behavior, and policy analysis. Its interdisciplinary approach allows for contributions to innovative solutions for contemporary economic and environmental challenges. The research aims to provide evidence-based insights that support policy development and promote sustainable economic practices.

The team is led by Professor Mikołaj Czajkowski, Head of the Chair of Microeconomics and Vice Dean for Research. His work focuses on consumer preferences, choices, and non-market valuation, earning him a place among the top five most influential economists in Poland (RePEc). With over 70 high-impact journal publications and more than 6,800 citations (Google Scholar), his research is widely recognized.

Senior Research Fellow Milan Ščasný collaborates with Charles University and international organizations such as the OECD, ECHA, and WHO-Europe. His research covers consumer behavior, non-market valuation, health risks, and impact assessment using macroeconomic models. He has participated in over 60 research projects and published more than 60 peer-reviewed articles, accumulating over 2,800 citations (Google Scholar).

Wojciech Zawadzki, Research Assistant and PhD candidate, focuses on behavioral factors using stated preference methodologies to improve the validity of discrete choice experiments and contingent valuation. Over the past five years, he has contributed to various research projects, resulting in six peer-reviewed publications.

Within the VISIONARY project, UNIWARSAW contributes to research on biodiversity-friendly food systems, consumer behavior, and policy development. Key activities include discrete choice experiments, case studies on short food supply chains, and analyses of consumer purchasing patterns. Further research examines the transition to plant-based protein, public procurement strategies for organic farmland, perceptions of the food system, and regulatory frameworks for sustainability.

Beyond research, UNIWARSAW hosted the first consortium meeting in Warsaw, contributed to the establishment of two science-policy interfaces—one on organic farming and another on short value chains—and will host a cross-country visit in 2025.
