Améliorer les avantages conjoints pour la biodiversité des solutions fondées sur la nature

The document outlines a comprehensive approach to integrating biodiversity co-benefits into nature-based solutions (NbS) for climate adaptation. It proposes a six-stage implementation cycle—ranging from system understanding and risk assessment to monitoring and learning—and emphasizes the need for a mix of biodiversity, structural, and functional indicators to measure success. The report highlights the importance of traditional knowledge, inclusive governance, and long-term monitoring to avoid socio-ecological trade-offs and ensure the sustainability of adaptation projects.

• Nature-based solutions (NbS) for adaptation are most effective and cost-efficient when they prioritize the conservation of intact ecosystems first, followed by the restoration of lost ecosystems, and finally the construction of new ecosystems with required functions.
• A global study of over 100 NbS adaptation projects found that while 54% had positive results for adaptation and ecosystem health, trade-offs occurred, such as the creation of non-native monoculture plantations.
• To ensure biodiversity co-benefits, the report proposes a six-step implementation cycle: (A) Understanding the system, (B) Risk and vulnerability assessment, (C) Identification of NbS options, (D) Evaluation of options, (E) Implementation, and (F) Monitoring, evaluation, and learning.
• Effective monitoring of NbS requires a combination of indicators covering biodiversity, structure, function, and ecological processes, rather than relying solely on coverage or species richness indices.
• Long-term monitoring over several decades is necessary to capture the full range of biodiversity co-benefits, as ecological improvements often occur years after the initial project implementation.
• Indigenous and traditional knowledge systems are essential for the design and implementation of NbS, as biodiversity is often highest on lands managed by Indigenous peoples compared to officially designated protected areas.
• The report identifies critical gaps in current NbS planning, including a tendency to neglect 'wetter' habitats, a lack of ecosystem function indicators, and insufficient consideration of future climate impacts such as species range shifts.
