This document discusses the connections between biodiversity and climate change. Climate change is a major driver of biodiversity loss through its impacts on ecosystems like changes in structure and function. Protected areas play an important role in both climate change mitigation and adaptation by storing carbon, capturing more through restoration, and maintaining ecosystem integrity and services. Opportunities exist for governments to increase protected areas' contributions to climate strategies through landscape approaches and expanding networks in high carbon/deforestation areas. Case studies from Belarus show peatland restoration providing mitigation, biodiversity, and economic benefits.
