Gunnar Dresßler

Research Interests

  1. Dynamics of socio-ecological resource use systems
    • Pasture use in dryland grazing systems under change, effects of new technologies and policy instruments, emergence of polarization between pastoralists (e.g. in terms of livestock numbers).
    • Thresholds of disaster management performance under change, loss of manpower, the role of information as critical resource.
  2. Human decision making in agent-based models.
    Journal Club "Human decisions in agent-based models of land use change"
  3. Remote sensing and GIS.

Current Projects

Member of the Junior Research Group POLISES - Global food security policies and their social-ecological side effects in regions prone to global change.
EU project emBRACE - Building Resilience Amongst Communities in Europe. (until Sep. 2015)
PhD thesis, working title: "Analysing resource use decisions under global change." as part of the projects "emBRACE" and "POLISES".
