Production, Consumption and Protection:
Modelling the Value Trade-offs in an
Agricultural Landscape
Kath Behrendt – ILWS PhD Student, Bathurst
Research Background….
 Changing face of agriculture
 Desire for a ‘tree change’
 Shift in societal goals from
production dominated to a more
multifaceted, variable and
contested mix of production,
consumption and protection
 Agricultural landscapes are now
being recognised for their
multifunctionality
 Conflicts and synergies arise from
provision of multiple landscape
functions, resulting in trade-offs
Research Problem….
 How can potential trade-offs resulting from the complex
mix of production, consumption and protection goals be
valued and modelled to assist decision making and
planning in multifunctional agricultural landscapes?
Research Objective….
 To evaluate the potential for rural development in
regional communities while simultaneously identifying
welfare enhancing levels of agricultural production and
ecosystem services.
