Global Perspective

Assessing potential future environmental changes helps policymakers decide where to take action and understand what the effects of policy can be. PBL uses scenarios and computer models to explore such future pathways. Scenarios are storylines and assumptions on potential future developments, and models use these to project future developments. Projections are presented in maps and graphs.

Three scenarios are used to show the impact of future developments:


a baseline scenario that includes assumptions on future land degradation


a scenario that includes restoration, improved land management measures, and protection of key ecosystems
