 20 – 22 September 2017. Bonn, Germany. Tropentag 2017: Future Agriculture: Social-ecological transitions and bio-cultural shifts.

The annual interdisciplinary conference on research in tropical and subtropical agriculture, natural resource management and rural development (TROPENTAG) was jointly organised by the universities of Berlin, Bonn, Göttingen, Hohenheim, Kassel-Witzenhausen, Hamburg, ZALF e.V., ETH Zurich (Switzerland), Czech University of Life Sciences Prague (Czech Republic), BOKU Vienna (Austria) and the

Council for Tropical and Subtropical Research (ATSAF e.V) in co-operation with the GIZ Advisory Service on Agricultural Research for Development (BEAF).

It was attended by 825 participants from 58 countries.

The Tropentag is a development-oriented and interdisciplinary conference. It addresses issues of resource management, environment, agriculture, forestry, fisheries, food, nutrition and related sciences in the context of rural development, sustainable resource use and poverty alleviation

Agricultural systems in developing countries are currently undergoing drastic changes. What are the implications of such developments and change processes for food security, resource base quality, rural well-being, and in general for the future of agriculture? These questions and related topics were addressed in plenary presentations and key note lectures in thematic sessions.

Workshop 8: The economics of improving seed systems of small scale farmers in developing countries
The purpose of the workshop was to come to a good understanding of the difficulties small-scale farmers face with the current trends in seed systems and to determine which opportunities they have to address these challenges.

  • Seed business vs. seed tradition: Commercial vs. subsistence crops, What are the economically most important quality deficiencies of seed presently used by small farmers? Under which conditions (crops, farming systems) are formal and informal systems and combinations profitable? How can you build and improve on farmers’ present seed systems?
  • Varietal portfolio: High yielding varieties vs. varieties adapted to present (often low) production intensity, homogenous crops vs. high genetic variability? How can small farmers get access to new varieties? Is a formally organized seed value chain a condition for this? Is dependency from supplier of seed a serious risk?
  • Food security : What is the impact of the shift in seed systems on food security? How important is agro-biodiversity regarding food security?
  • Seed policies: Role of quality and certification of seed. Formal vs. informal seed systems. How can policies support good quality seed for farmers? How can we best take into account farmers’ practices? How to ensure that seed is available and affordable to small-holder farmers?
  • Influence of output markets on seed systems: How do output markets and market orientation of farmers shape the prevailing seed system in different crops? How do output markets influence the varietal portfolio of farmers?
