The document discusses a nexus initiative that aims to address interconnected water, energy, and food challenges in Ethiopia through applying a nexus toolkit. It presents a case study examining the impacts of different development pathways on stakeholders in Lake Tana, Ethiopia. Three scenarios are developed - Business As Usual, National Plans, and Nexus. Results show the Nexus scenario leads to lower water production but higher energy and food production compared to the other scenarios by better managing limited water and biomass resources across sectors. The conclusion discusses how nexus issues can be practically managed between institutions and the need for new policies and innovations.

2. 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.

3. 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

7. 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

13. 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?
