Linkages Among Various Ecosystem Components

Water use and agrochemical runoff

Water availability

Erosion and changes in water flow

Habitat loss and fragmentation

Reduced resilience

Temperature changes

CO2 release and sequestration

Reduced resilience

Fishing impacts

Temperature and pH changes

Hydrologic, CO2 and temperature changes

Greenhouse gas emissions Precipitation

and temperature Land transformation

Loss of crop
