Integrating tenure and governance into assessments of forest landscape restoration opportunities

  • Many countries have adopted the Restoration Opportunities Assessment Methodology (ROAM) to guide the development of national and subnational restoration strategies.
  • This study analyzes ROAM reports for eight countries to determine the extent to which tenure and related governance considerations were incorporated.
  • Although all of the reports found that lack of rights or weak rights impeded efforts to scale up forest landscape restoration (FLR), none provided robust descriptions of the rights and responsibilities of individuals or communities to trees, forests or land under statutory or customary law.
  • We propose a rights actualization framework as a diagnostic that can provide a solid foundation to identify policy reforms needed to address rights-related barriers to FLR implementation.
  • FLR initiatives informed by a robust tenure rights assessment will enhance the likelihood of achieving their twin goals of improving ecological functionality and human well-being.

Impacts of forestation on water and soils in the Andes: What do we know?

Key messages

  • This brief summarizes the findings of a systematic review on the impacts of forestation on water and soils in the Andes (detailed in Bonnesoeur et al., 2018).
  • Exotic tree plantations and, to a lesser extent, native forests consume water and therefore often reduce the total water supply to downstream users in most Andean regions.
  • Only in areas immersed in clouds, such as in the eastern slope of the Andes, might native forests increase downstream water availability compared to other land covers.
  • Decreased total water supply could be acceptable to many users if it confers other benefits, such as increased water availability during the dry season or a reduction in water turbidity.
  • When trees, including exotic species, are planted on degraded soils (bare and/or compacted soils), they can improve soil infiltration, reduce peak flows and control erosion.
  • Exotic tree plantations on well-conserved grasslands (páramos, jalcas, punas) have detrimental impacts on total water supply and hydrological regulation.
  • Existing native forests provide excellent water regulation and erosion control, more than mature tree plantations.
  • As restoring degraded native forests does not necessarily recover original hydrological services, the conservation of existing forests must be a priority for watershed management.
  • The hydrological impacts of native species forestation, however, have largely been overlooked and require further research.
  • Long-term hydrological monitoring and research are necessary to fill the multiple data and knowledge gaps identified in this review.
