Key Areas For Management

1. Inland areas - which affect the oceans mostly via rivers

2. Coastal lands - swamps, marshes, and so on - close tothe sea, where human activities can directly affect the

adjacent waters3. Coastal waters - estuaries, lagoons, and shallow

waters generally, where the effects of land-basedactivities are dominant

4. Offshore waters - out roughly to the edge of thecontinental shelf

5. High seas - largely beyond the 200-mile EEZs ofcoastal states' control

Present Challenge

No clear geography

Highly focused on the narrow land/saltwater interface

Diminishing focus further from thisinterface

Poor buy-in from agencies andstakeholders with responsibilities for: Land

Freshwater Estuarine

Marine

marine environments Supports buy-in from agencies and

stakeholders with management

responsibilities

New approaches and concepts,building on lessons learned

Improved management Engagement of people and agencies

across jurisdictions and sectors
