Élucider les solutions climatiques basées sur la nature pour l’adaptation

This policy brief clarifies the conceptual framework of Nature-based Solutions (NbS), specifically focusing on Nature-based Climate Solutions (NbCS) and Ecosystem-based Adaptation (EbA) for climate change adaptation. It outlines the requirements for these solutions to be effective, provides practical examples across various ecosystems, and discusses the social and environmental safeguards necessary to prevent rights violations and biodiversity loss.

• The document distinguishes between several overlapping concepts: Nature-based Solutions (NbS) is the umbrella term for measures protecting, conserving, and restoring ecosystems to address social, economic, and environmental challenges. Nature-based Climate Solutions (NbCS) are a subset of NbS focused on climate change reduction and adaptation while supporting biodiversity. Ecosystem-based Adaptation (EbA) is a specific type of NbS or NbCS focused specifically on helping society adapt to climate change rather than mitigation.
• For a project to be classified as NbCS for adaptation or EbA, it must meet four specific criteria: it must be specifically oriented toward managing current and future climate risks and strengthening ecological resilience; it must target and benefit specific groups and livelihoods based on risk or vulnerability assessments; it must integrate ecosystem processes; and it must consider local environmental, economic, social, cultural, and traditional contexts.
• The document provides several case studies of NbCS in practice: in Mongolia, the restoration of 10 ha of wetlands and improved management of 72,000 ha of pastures and 254 ha of forests reduced surface water extraction for agriculture by 20%. In Ecuador, climate-smart livestock and cocoa production increased productivity by over 12% and incomes by over 16%, while preserving 3,275 ha of forests. In Russia, the large-scale restoration of 35,000 ha of peatlands reduced annual emissions by 175,000 to 220,000 tonnes CO2eq and protected 20 million people from smoke and smog. In the Seychelles, coral reef restoration increased coral cover from 2% to 16% and multiplied fish abundance by five.
