IPPAE Program

Welcome to IPPAE - the International PhD Program for Agricultural Economics, Bioeconomy and Sustainable Food Systems at Justus-Liebig-University Giessen!

Within the IPPAE program…
The International PhD Program for Agricultural Economics, Bioeconomy and Sustainable Food Systems (IPPAE) was first accredited in 1992 by the funder, the German Academic Exchange Office (DAAD). The program is the result of a cooperation between the agricultural economics groups of the University of Hohenheim and the University of Giessen. The program is highly competitive and interdisciplinary. Its strength is that all PhD candidates have prior research or work experience in an area close to their PhD topics, which strengthens their analytical skills as well as the amount of knowledge that can be passed from peer to peer. In Giessen, the IPPAE lays its thematic focus on empirical, problem-solving research, at the crossroads between agricultural economics, agricultural sociology, farm economics and sustainable resource use. To date, more than 130 candidates received their PhD through the IPPAE Giessen.
