3. The nexus is scale and context specific
• Global scale– CC scenarios, new climate economy, gobal compact?
Macro-Region scale
– Economic, social , trade, health, education, peace and security
– Building common objectives, norms and values - ”Energy union”
• National scale
– Policy cohesion to address multiple national objectives
– E.g hydropower storage as a lever intermittent renewable energy
Basin/Catchment scale
– Competition & tradeoffs between users: irrigation, hydropower, domestic
water supply
– Finding synergies and new win-win opportunities
Urban scale
– Resource stocks and flows external and internal, business models for
services

Catchment scale: Nexus research inLake Tana & Beles river basin, Ethiopia
Drivers
• Economic + population
growth, national growth plan
• Increased irrigation
development
• Subsistence to commercial
agriculture
• Foreign direct investments
into biofuels
• Hydropower development
• Environmental degradation
”Irrigation for food or hydropower for
energy production”?
”Change in HEP´operation rules for
multiple benefits”

7. Conclusion – Nexus Value Add
• Increases the understanding of dynamic systemstaking multiple sector objectives into account
– Analytical approaches that are scale and context specific
– From qualitiative to quantiative analysis
– Linkages/challenges/options
• Contributes to assess governing options at different
scales
– Norms, institutional structures and options
– Policy coherence
• Identifies management options & innovation needs
– Resource planning
– Operational aspects, synergies & tradeoffs
– Solution oriented
