This Festschrift in honour of Professor Dr. Dr. h.c. P. Michael Schmitz covers theoretical as well as empirical works on challenges prevailing in the food and agricultural sector. Discussions of conflicts between social and ecological requests of citizens and market outcomes are provided. The contributors discuss options of policy interventions as well as their limitations. Empirical facts that can contribute to a more evidence based policy formation are also presented. The book itself consists of two parts: «agri-food markets and policies» and «agriculture, trade and development». Topics covered are moral, markets and policies, farm animal welfare, fat taxes, agricultural derivatives markets, future food value chains, free trade agreements, food security, food waste and climate change. von Hartmann, Monika und Hesse, Joachim W.
