Six years of practical experience in farming:
Working and living in three Kibbutzim and two Moshavim in Israel (1981-1984): Irrigation, tractor driving, orchard management, cow milking, vegetable growing, turkey and chicken rearing. Toranut (i.e. obligatory community services such as dish-washing, kitchen work, dining-hall service, laundry, night-milking and seasonal harvest work).
Volunteer of Action Reconciliation and Service for Peace on an reconstructed ancient rainwater harvest farm of Professor Michael Evenari (Chair of Botany, Hebrew University of Jerusalem – Balzan price winner in Applied Botany together with Professor Otto Lange 1988) at the Nabatean city of Avdat in the Negev Desert, Israel (1984-1985). Field work and assisting Prof. Ernst-Detlef Schulze and Prof. Rainer Horn in the collaborative research center DFG SFB 137 “Flux Control in Biological Systems: From Enzymes to Populations and Ecosystems” which sparked my interest in studying agroecology.
Two year dual-education apprenticeship. 1st year: Teaching, demonstration and experimental farm of the North Rhine-Westphalian Agricultural Extension Service at Haus Düsse located in the Soester Börde: Entire range of common cattle and pig rearing forms, feeding methods, milking systems, field cultivation methods, crop and animal breeding trials, slaugther and egg laying performance tests. 2nd year: Farm worker on a mixed-farm on the Haar hills near Lake Möhne (1985-1987)
