Landscape Restoration: Definition and Principles
• Restore entire landscapes; not just individual sites
• Use a package of restoration strategies – no “one size fits all”, based on
existing good approaches
• Restore functionality and ecosystem services – aim for multiple benefits
• Adapt to circumstances over time
• Involve stakeholders
• Avoid further reduction of natural ecosystems
Long-term process to regain ecological functions and
enhance human well-being in degraded landscapes
Landscape Restoration: Assessment Method
Restoration Opportunity Assessment Method (ROAM): Process
Step 1Identify land use challenges
Step 2Identify and map landscape restoration options
Step 3Conduct cost-benefit analysis, including carbon sequestration potential
Step 4Analyze enabling conditions – policies, market, and institutionsS
