3 When do land-based activities affect the success of marine resource management?

5 freshwater water quality oysters crab and fish Simple models for application in the 3 systems?

6 The InVEST Tool Integrated Valuation of Ecosystem Services and Tradeoffs

7 Water Yield and Scarcity Reservoir Hydropower Production Freshwater Purification: Nutrient Retention Sediment Retention Avoided dredging and water quality regulation Managed Timber Production Crop Pollination Renewable energy: waves Coastal Vulnerability & Protection Aquaculture: finfish & shellfish Aesthetic quality Fisheries Recreation Habitat risk assessment Marine water quality http://www.naturalcapitalproject.org/
