The Council for Tropical and Subtropical Agricultural Research (ATSAF e.V.) is a network for scientists and experts concerned with development-oriented research in the tropics and subtropics. This year was the 25th ATSAF e.V. member meeting. Besides funding options for students and researchers it offers a platform to interconnect national and European scientists and organizations. Students, Doctors and young scientists can especially benefit from the network already in their early career since it helps to build up long-term relations with other researchers and offers access to research programs, says chairman Prof. Dr. Folkard Asch from the University of Hoheneheim. Since 1997, in cooperation with the participating universities and by the support of sponsors, ATSAF e.V. organizes the Tropentag.
