  18. 18. Final  workshop:     amended  beliefs  and  learning   –  Less polarized debate between agencies –  Greater recognition of sectoral feedbacks and tradeoffs –  Integrated research approaches and multi sectoral deliberations favoured –  Avoid panaceas: diversity in policy deliberations and targeted implementation strategies –  Some science outputs readily adopted (eg rice salinity tolerance) Structured problems –  a different science role in unstructured problems: sustained negotiation and iterative solutions MERFI  -­‐  Mekong  Region  Futures  Ins6tute  
  19. 19. Final  workshop:     amended  beliefs  and  learning   – Emphasize the importance of the participatory process to discover adaptation strategies – Accounting for National development agendas is crucial MERFI  -­‐  Mekong  Region  Futures  Ins6tute  
  20. 20. Key  lessons  from  ChaRL:   1.  To avoid project irrelevance and sustain engagement, Partners need to identify the problem and co-design research and criteria of success 2.  Cross sectoral impact can only be achieved through participatory processes if: A.  The problem involves multiple sectors with contested values and objectives AND B.  The problem requires integration of multiple sources of uncertain information and knowledge 3.  Developing future visions is a crucial step to replace sector objectives with a plausible shared normative benchmark 4.  Use tools/methods to manage complexity and assist decision makers discover sustainable solutions 5.  Evaluation metrics need to correspond with the research question.
