Key Biodiversity Areas (KBAs) – sites that contribute significantly to the global persistence of biodiversity – are a critical piece of the sustainable development puzzle. Safeguarding KBAs not only conserves biodiversity, it also provides valuable benefits to people – what we call “ecosystem services.” These services include freshwater provision, climate regulation, flood protection, food security, cultural values and many others. KBAs were first identified in Myanmar in 2005 and subsequently refined in 2012, and these data are being used to strengthen Myanmar’s protected area system. At the same time, a global KBA standard was finalized in 2016. This new standard provides scientific criteria to support the identification, monitoring and conservation of these important sites. While KBAs are identified based on biodiversity, the new standard emphasizes the importance of documenting the benefits to human well-being of safeguarding these sites. To address this need and with support from the Science for Nature and People Partnership (SNAPP), we led a working group that developed a framework for documenting, measuring and valuing ecosystem services delivered by KBAs. We chose to pilot this approach in Myanmar, recognizing the high stakes for sustainable development in that country. Building on previous work and with the use of spatially explicit data on ecosystem services, our SNAPP working group convened policy experts, government decision makers, scientists and civil society organizations to better understand how KBAs can support Myanmar’s commitments to biodiversity conservation and sustainable development. These include the Aichi Biodiversity Targets and Sustainable Development Goals. We have a unique window to achieve sustainable development in Myanmar, and are hopeful that this work will ensure effective management and conservation of Myanmar's diverse ecosystems and associated natural capital. Safeguarding key biodiversity areas provides a promising mechanism to ensure the maintenance of the country’s unique biological diversity and the many benefits it offers to diverse human communities. As the first country in the world to nationally employ the ground-breaking KBA Partnership established between the world’s leading conservation organizations, Myanmar has an opportunity to serve as a global example for how to include biodiversity in sustainable development.
