Scenario 2. Agriculture

This decision tree is a sample scenario that can guide the selection and interpretation of indicators in situations where

managers are concerned about inland land use, particularly agriculture. The most significant issue with agriculture is the

runoff and contamination from agro-chemicals (including nutrients) and sediments.

This sample decision tree therefore focuses on these three areas to monitor:

· Status of key ecological parameters impacted by agriculture (sedimentation rate, ocean color)

· Estimated level of main threats (e.g., sediment delivery rate)

· Effectiveness of interventions (e.g., agricultural input rates, contaminant accumulation in marine life)
