Introduction
 Scarcity of food, energy and water worldwide
 Inter-linkages between the three sectors
 Food-Energy-Water Security (FEW) Nexus –
Opportunities and Challanges resulting from
inter-linkages
 Formulating the concept of FEW Nexus

e.g. Good
governance in natural

management
e.g. Rainfall e.g. Exchange rate

• Drivers affecting the system of food, energy and
water are both outcome and effect.
• Direct vs. indirect drivers
• Endogenous vs. Exogenous drivers

 Time horizon: Short-term or medium-term
impacts
 Multidimensionality: Macro (global,
regional and national) as well as micro
(household and individual) level

Definition of the FEW Nexus
The FEW nexus encompasses synergies and
trade-offs between food, energy, and water
security which are impacted by endogenous
and exogenous drivers and cannot be
captured if these sectors are analyzed in
isolation.

Nexus interventions
 Definition of a nexus intervention:
The intervention must impact food,
energy, and water security, of which at
least one impact must be direct.
 Interventions often affect endogenous
drivers (e.g. price and availability) which
have a direct effect

Applying the Nexus approach –
General challenges
Page 10
 Commonpool resources within the nexus.
 Necessity of specific solutions for property
rights on commonpool resources
 Food, energy and water security are global
public goods
 Lack of global security enforcing
mechansims
 Replace silo approach by a system
approach

11. INTERNATIONAL FOOD POLICY RESEARCH INSTITUTE
Applying the Nexus approach –
Challenges for policymakers
 Little incentives due to large barriers for
ministries to collaborate
 Pitfalls of Individualism
 Reasons for cooperation
 Lack of responsibility

Applying the Nexus approach –
Possible strategies for policymakers
Nexus policymaking:
 Develop and agree on common goals
 Share responsibilities to obtain goals
 Work together to achieve goals
Nexus gatherings:
 Coordination of non-participating ministery
 Collective resoponsibility by ministries
 Horizontal accountability

Applying the Nexus approach –
Challenges for other stakeholders
 Researchers: lack of articulate framework,
time constraints for group processes,
language barriers, publishing concerns
 Private sector: incentive to work on
common problem
