Farms are decision points across spatial, temporal and institutional scales Global institutions But a major challenge remains in reconciling 3 time scales relevant to various decision makers: National institutions Globe institutions National economy Nation Product value chains Water-shed space Desakota network Land-scape Community time Farm Persistence Efficiency Patch/field Change Population Organism Gene Jackson, L.E., van Noordwijk, M., Bengtsson, J., Foster, W., Lipper, L., Pulleman, M., Said, M., Snaddon, J. and Vodouhe, R., 2010.

Sustainable Weighting of Economy-Ecology Tradeoffs: Organized Reduction or Stretching Our Use of Resources? (SWEETorSOUR?) This may be societal optimum, but requires SWEET Production Possibility Frontier Getting here may turn SOUR
We need empirical data, comparative analysis of how SWEET could be made to work and how SOUR can be avoided. Comparison of 8 sites in a global network starts to give insights… Jackson et al under review Old-growth forest
Jackson et al., under review Reliance on natural capital & ecolo-gical processes for production Agrotechnical intensification
Field-scale actions Landscape-scale actions Jackson et al., under review
Key research challenges • Quantify buffer & filter functions at patch/ field/landscape scalesunder influence of ‘intensification’ (or alternative intensification pathways) • Quantify need for increase in buffer/filter functions in response to increased climate variability • Social & economic institutions to support SWEET and avoid SOUR
