MERFI Nexus in Methods and Processes

What does the Nexus mean for Methods and Process? Dr Alex Smajgl

Mekong Region Futures Institute

Multiple sectors = Multiple disciplines

• Specific tradeoffs: • Energy-water trade-offs

• Hydrological models •  System dynamics models

• Water-food trade-offs •  Agronomic models and crop models •  Integrated hydrological models (primary prod è fish)

• Food-energy •  System dynamics models •  Land use change models

• Nexus-wide dynamics • Agent-based models • Bayesian Belief networks

MERFI - Mekong Region Futures Institute

Cross sector dialogue


• Process design critical for cross sector dialogue especially

•  If issues highly contested •  If issues very complex


The Ideal: Vision-based decision making


Visions to replace sector mandates = normative benchmark

Mapping visions & future scenarios Plausibility & desirability

Example Vision for Mekong Delta


Cause–effect assumptions


Understand and test underpinning beliefs


Revisit decision options with new vision & new beliefs

Sector optimum vs. Nexus optimum
