Trade-offs – and synergies?
• Resource scarcity – and resource use efficiencies• Time scale – productivity vs. sustainability• Spatial scale and hierarchical level
– Field, farm, farming system, terroir, landscape, watershed, region, country, globe
– Physical/geographical vs. political levels
• Claims – from global to local• Win-win? – win-lose – or lose-lose scenarios• Power – whose voice, whose power
• Methods and approaches • Key questions and hypotheses
…increases in the efficiency with which a resource is used lead to
faster depletion of that resource…
