First Principles/Assertions
• Ecological Services are essential elements of
sustainable and resilient food systems
• All components of food security - availability,
stability, access, and utilization – are affected by
environmental change (from anthropogenic or
“natural” sources)
“Ecosystem goods and services represent the benefits
human populations derive, directly or indirectly from
ecosystem functions” (Costanza et al. 1997)

Climate change will affect supply and the ability of individuals to use
food effectively by altering the conditions for food safety and
changing disease pressure from vector, water, and food-borne
diseases

Change
• The integrity of ecological systems can determine
the diversity and the quality of ecological services
• Environmental changes alter ecological services
and dis-services to food systems and food
security
• The spatial scale of this dynamic can be local to
regional
