The ABCDR project investigates why agroforestry systems are not more widely used and how this could change in the future. For this purpose, we analyse the biophyiscal potentials, the decision-making processes of farmers, and the role of climate and agricultural policy. We work with different scientific approaches, incorporate stakeholder knowledge and practice, and use computer simulations to explore both the biophysical potential and possible agro-economic future pathways in which agroforestry systems play a greater role than they do at present. The three-year research project ABCDR started on 1.8.2022, and is carried out by scientists from the Potsdam Institute for Climate Impact Research and the University of Bonn. It is part of the CDRterra research programme of the Federal Ministry of Education and Research.
