Papers in this proceedings document the partners' presentations and the output of the discussion groups during the workshop held in Budapest to define areas where more basic research that uses tools which assess diversity, its structure and changes would be needed. Participants from Burkina Faso, Morocco, Zimbabwe, Mali, Peru, Vietnam, Tunisia, Hungary, Bolivia, Nepal, Australia, Italy and the US presented their ideas and information from their own work on enhancing the use of crop genetic diversity to manage abiotic stress. This was followed by three working-group sessions on abiotic stress issues. The first session sought to define key questions on the link between abiotic stress and genetic diversity. The second discussion examined questions about farmers' management of genetic diversity under stress conditions. The third session explored the possible intensification of abiotic stresses due to land degradation and climate change. The final working-group period addressed the range of abiotic stresses as they afflict crop production, and criteria for ranking them. Major abiotic factors on-farm included not only drought, cold and salinity, but also low soil fertility (characterized as nitrogen and phosphorus deficiency), boron and iron deficiency, boron toxicity, soil acidity, erosion, waterlogging, and climatic disasters such as flooding and hurricanes. Drought was ranked as the highest priority, followed by low soil fertility, soil acidity and cold stress
