The SEI WEF nexus initiative
• Governing the nexus
• Understanding the nexus
• Managing and innovating in the nexus
Aim: to apply a nexus toolkit to address inter-connected water, energy and food development challenges at different levels. The initiative will do this to enable those who govern and manage these systems to work together to ensure basic access, efficiency and sustainability.

The Water, Food, Energy and Environment Nexus: a case study in Lake Tana, Ethiopia
• Sustainable agricultural transformation and energy transitioning
• Conflicting interests and aspirations
• Policy impacts: CRGE, GTP
Aim: Assess impacts of different development pathways on various stakeholder groups, after accounting for interactions between sectors

Scenarios: three stories about the future
• Business as usual (BAU): slow development, low adoption of new technology
• National plans (Nat Plans): full adoption of technologies according to national policies
• Nexus (Nexus): resolving outstanding dilemmas, new policy and innovation needs
Population increase: same in all scenarios, no climate change accounted for

Points for discussion / conclusion
• Links beween sectors need to be accounted for
• Water and biomass are limited resources and their management needs to be agreed upon across sectors
• How can these nexus issues be managed practically between institutions?
• What is the need for new policies, innovations and implementation options?
