  • 1. A World of Opportunity - Global Potential for Forest Landscape Restoration Lars Laestadius, World Resources Institute & Peter Potapov, South Dakota State University ABSTRACT: Forests have paid a high price for the growing human need for food, feed, fuel and timber. More than three quarters of the world’s forests have been cleared, fragmented or degraded while almost half have disappeared completely. Just one fifth remains undisturbed in tracts that are large enough to maintain all their natural functions. The consequences are immense. Degradation harms local livelihoods. Loss of ecosystem services causes local poverty and downstream disasters. Biodiversity may be irreversibly lost. Yet restoration is possible. Poor people can turn degraded lands into healthy, productive and biologically rich assets within a few years if given long-term secure rights and good technical advice. Restoration can stimulate economic growth in poor rural areas, increase carbon stocks and ecosystem resilience and reduce the risk of natural disasters. Restoration should focus on restoring or enhancing the functionality of a landscape (that is, its supply of ecosystem services)—not on maximizing new forest cover. Site level decisions should be made with the greater context of the landscape in mind so that trade-offs among conflicting interests are possible. Local stakeholder involvement in decision- making and implementation is essential. Promotion of spontaneous (“natural”) regrowth should be a viable option along with tree planting. A preliminary geospatial assessment by the authors suggests that more than a billion hectares of deforested and degraded land are available for broad-scale or mosaic type restoration. The opportunities for restoration are more evenly distributed among developing countries than the opportunities to avoid deforestation which makes restoration an interesting addition to REDD plus. *** DISCUSSION: Covered questions regarding the huge potential for greater integration between agriculture and forestry, and the need to include more economic assessments within biophysical models. Funding has been allocated to do this at a country level for both Ghana and Mexico in the coming months.

  • 7. Forest Landscape Restoration: not a top-down, one-size fits all solution • Brings people together to identify, negotiate, and implement practices . . . • . . . that restore an agreed optimal balance of the ecological, social, and economic benefits of forests and trees . . . • . . . within a broader pattern of land uses
  • 8. Forest Landscape Restoration Functionality, not forest Landscapes and sites Local needs and high-level priorities Aided regrowth and planting Adaptive management

  • 10. Area of Investigation
  • 11. Potential Forest Extent forests (darker green), woodlands (lighter green)
  • 12. Current Forest Extent green – forests, light green – woodlands/sparse tree cover, yellow – deforested
  • 13. How much is left? 43% 41%Forest Woodlands
  • 14. Potential Forest Landscapes: Status Dark green - intact forest landscapes; Green - natural/managed forests; Very light green - natural/managed woodlands Lighter green – degraded forests; Orange - degraded and partially deforested forests/woodlands; Red - deforested forests/woodlands

  • 16. Lands with potential for broad-scale restoration Degraded or deforested areas, sparsely populated, not used to produce crops. Capable of supporting closed forest. China Madagascar
  • 17. Lands with potential for mosaic restoration Degraded or deforested areas , may have extensive land-use and high population density. Capable of supporting closed forest or sparse woodlands. China Russia
  • 18. Human pressure (land-use intensity and population density)
  • 19. Opportunities for Restoration Dark green – broad scale restoration (degraded or lost forest, low population, no croplands) Light green – mosaic restoration (pastures, agroforestry mosaics, mosaics of crops and other vegetation, abandoned lands, etc) Bright yellow – irrigated croplands protective restoration Light yellow – rainfed croplands, plantations protective restoration
