Biodiversity and Climate Change: Avenues for Adaptation
Biodiversity and climate change - Avenues for adaptations by Sarath Ekanayake discusses how biodiversity in Sri Lanka provides essential services but is threatened by climate change, and outlines strategies to help biodiversity adapt. Sri Lanka has a great diversity of ecosystems and species, and biodiversity underpins the country's economy, food/water security, and tourism. However, climate change is causing issues like increased flooding and drought that impact forests, agriculture, and human-wildlife conflict. The document recommends identifying vulnerable biodiversity, reducing non-climate pressures, and enhancing resilient landscapes through actions like conserving forests, controlling fires, and accommodating wildlife in urban areas to help biodiversity adapt to climate change impacts.
