Слайд 3

What is „the nexus“ ?
an integrated approach promoting “systemic thinking”
e.g. externalities,

tradeoffs, synergies

Why do we need it ?

increasing demand for natural resources,
for food, energy and other human securities, threatens environmental sustainability , ecosystem services
-> need for sustainable intensification
-> need for coherent policies across scales
-> to be supported by multi-scale, cross-sectoral analyses

How to implement it?

mostly through case studies: Burkina Faso (food-biofuel) , Mauritius (sugarcane for biofuel), MENA (climate adaptation – mitigation), California, Blue Nile

Слайд 4

Tool box for nexus tradeoff analysis,
integrated scenarios, policy and investment

support

WEAP / LEAP (AEZ)

to be developed jointly with stakeholders and scientists
simulating long-term resource allocations,
integrated network-based demand and supply analysis,
transparent, flexible, user-friendly, low initial data requirements,
similar user interfaces and terminologies,
widely used in ministries, authorities, bureaus, NGOs, universities etc: 100s of users worldwide.
for free to non-profit developing country institutions
frequent trainings in Sweden, but also in various regions (plus online tutorials and handbooks)

Слайд 6

WEAP Water Evaluation And Planning www.weap21.org
Integrated watershed planning, matching demands and supplies

GIS-based, graphical drag & drop interface
Additional simulation modeling possible: land use effects, groundwater dynamics, crop water use, crop productivity, water quality, reservoir management & hydropower financial module

Слайд 7

LEAP Long range Energy Alternatives Planning System
Typically organized by sector, subsector,

end-use and device.
Users can edit the tree on-screen using standard editing functions (copy, paste, drag & drop)
Structure can be detailed and end-use oriented, or aggregate (e.g. sector by fuel).

Слайд 8

Cost-Benefit Analysis (“externalities”) in (WEAP) LEAP
Societal perspective of costs and benefits

(i.e. economic not financial analysis).
User specifies boundaries
Cost-benefit analysis calculates the Net Present Value (NPV) of the differences in costs between scenarios.

Слайд 9

Previous case studies (KTH, SEI) Mauritius
Energy Security in changing Climate conditions

Small island with clear boundaries- data availability
Producer and exporter of sugar (occupying 80 % cultivated land area)
Dependent on fuel imports for its energy requirement
Highly vulnerable to climate change
Nexus („CLEWs“) approach formally adopted for national policies by the government

Слайд 10

(CLEW Integration, KTH)
Increasing Population (water demand, energy access, food security)
Land locked

country
Population increase and urbanization (centralized demand)
Dependence on one main export crop (cotton)
Continuous deforestation
No own fuel resource – Dependence on wood for as energy source
Agricultural intensification on suitalble land for food security, biofuel production and reduced emissions.

Previous case studies (KTH, SEI) Burkina Faso

Слайд 11

Water for Energy and Energy for Water
The water sector accounts for

19% of California’s electricity consumption
Importation of water from North to South California
Proposed scenario: introduce a share of water supply (5%) from desalination of sea water
Result: quantified tradeoff: increased energy consumption vs water saved (not imported)

Previous case studies (KTH, SEI) California

Слайд 12

Application of the nexus concept to the Ethiopian Blue Nile
Supporting ongoing

activities, plans and strategies e.g. GTP & CRGE: agricultural intensification / commercialization / irrigation,
renewables / hydropower / bioenergy crops
Identifying pathway to achieve goals such as:
improved water use efficiency (GTP)
avoiding further cropland expansion (CRGE)
For discussion: how are the national goals broken down into Blue Nile planning and management?

Слайд 13

proposed focus on biomass production,
tradeoff analyses / testing different strategies,

e.g.
small- vs. large-scale storage
water for hydropower vs. water for agriculture
water for biofuels vs. water for food production
energy for agricultural intensification
goal: „improved landscape configurations“ for resilience

Application of the nexus concept to the Ethiopian Blue Nile

Слайд 14

National Model on LEAP (to be linked with Blue Nile Basin

Model on WEAP and eventually with Land Use using GAEZ)
Disaggregation of data from Blue Nile Region

Initial LEAP model for Ethiopia / Blue Nile

Слайд 15

Слайд 16

Initial WEAP model for Lake Tana

Слайд 17

Initial WEAP model for Lake Tana
quantifying upstream <–> downstream effects and

tradeoffs

Слайд 18

do sectors cooperate?
Implementing the nexus
agriculture
water
energy
institutional network analysis
inter-agency coordination, e.g. via interministerial

steering group (CRGE)
