2GECAFS Vision
A food-secure future for those most vulnerable to
environmental stress.
3Fundamental Questions
- How will Global Environmental Change affect the
vulnerability of food systems in different
regions? - How might food systems be adapted to cope with
GEC so as to enhance food security? - What would be the consequences of adaptation
options for environmental and socioeconomic
conditions?
4Key Terms
- Global Environmental Change
- changes in the biogeophysical environment
- Food Systems
- an interconnected set of processes and activities
- Food Security
- a state or condition underpinned by food systems
5Global Environmental Change Changes in the
biophysical environment caused or strongly
influenced by human activities
For example changes in
Land cover soils Atmospheric composition
Climate variability means Water availability
quality
Nitrogen availability cycling Biodiversity Sea
currents salinity Sea level
6Global Environmental Change
- Examples of human activities leading to GEC
Agricultural intensification Freshwater
extraction Fisheries overexploitation Waste
production
Deforestation Fossil fuel consumption
Urbanisation Land reclamation
7Components of Food Systems Key Elements
FOOD UTILISATION
FOOD ACCESS
- Affordability
- Allocation
- Preference
- Nutritional Value
- Social Value
- Food Safety
FOOD AVAILABILITY
- Production
- Distribution
- Exchange
8Food Security
- exists when all people, at all times, have
physical and economic access to sufficient, safe,
and nutritious food to meet their dietary needs
and food preferences for an active and healthy
life. - (definition from the World Food Summit)
- emphasizes access for individuals, households,
communities to food.
9GECAFS Goal
To determine strategies to cope with the impacts
of GEC on food systems and to assess the
environmental and socioeconomic consequences of
adaptive responses aimed at improving food
security.
10Achieving the Goal
- Improve understanding of the interactions between
food systems and key socioeconomic and
biogeophysical components of the Earth System. - Deliver the new science necessary to assist
policy formulation for improving food security in
the face of GEC. - These are to be undertaken simultaneously

- 1. Conceptual Methodological Research
- Food Systems Concepts
- Vulnerability Concepts
- Scenario Construction
- Decision Support Systems
- 2. Food Systems Research in
- Indo-Gangetic Plain
- Caribbean
- Southern Africa
13Conceptual Methodological Research
- Develops a GEC science agenda that
- targets generic science issues
- improves understanding of the interactions
between the Earth System and Food Systems - integrates natural and social sciences
- adds value to basic science by underpinning
applied science - underpins regionally-based food systems research

Current Food Systems
Adapted Food Systems
Adaptation
- International networking approach
- Led by small, specialist committees
- Coordinated by dedicated Science Officers
- Specific funding applications, mainly to science
agencies
14Regional Food Systems Research
- Develops a GEC science agenda that
- targets regional scientific issues
- relates to regional development needs
- interacts effectively with the regional policy
making process - encourages more support for the regional science
communities - provides contexts for conceptual research

- Regional studies approach
- Led by regional scientists assisted by GECAFS IPO
- Specific funding applications, mainly to

19GECAFS Research on Decision Support Systems
Initial Workshop University of Reading, UK
August 2003
- The nature of DSS in general and the modelling
tool in particular - Types of output parameters needed by policy
makers and at resolution - Types of input parameters as needed by model
designers - Other aspects of DSS and modelling that need to
be considered
20Activities since Reading Workshop
- Follow-up discussions with regions scientists,
resource managers, policy-makers and donors - gt reviews of information needs
- Improved definitions of other GECAFS conceptual
research areas - Collaboration with USDA established
- GECAFS/USDA DSS Science Officer in post in UF
21Decision Support Systems research questions
- What is the best way to determine the information
needs of advisors to policymakers, resource
managers and other stakeholders regarding GEC and
food issues? - How can DSS best be developed to help analyse the
socioeconomic and environmental tradeoffs of
adaptation options? - What is the best methodological approach to DSS
development to optimise communication with
stakeholders?
22Decision Support Systems development process
- Users must
- help define what goes into DSS
- help design the interface and information content
- play a major role in evaluating/refining DSS
- help develop educational materials for DSS
- Must link closely with scenarios exercises
23Gainesville Workshop GECAFS / USDA-ARS / UF
To establish the overall frame for the GECAFS DSS
project
- Specific Workshop Objectives
- ascertain the nature of environmental and
socioeconomic information needed to support
improved policy formulation for food security - identify how DSS can be used to help develop
and interpret scenarios of changed environmental
and socioeconomic conditions at various spatial
and temporal scales - determine the types of information needed for
developing DSS
