Global Delta Risk Index for the Ayeyarwady Delta (Myanmar)

This dataset provides the Global Delta Risk Index (GDRI), devised by Hagenlocher et al. (2018), tailored specifically for the Ayeyarwady Delta in Myanmar, and associated exposure metrics of population and ecosystem as a pivotal tool for the systematic evaluation of vulnerability and multifaceted flood risk, as developed by Vogel et al. (2024). We combine 55 indicators of social- and ecosystem vulnerability with 100-year, 500-year, and 1,000-year scenarios of pluvial, fluvial, and coastal flooding hazards and exposure at the sub-delta scale. Using townships as units of analysis allows for bridging the gap between global and local case studies, providing insights that are meaningful for the risk-informed development of the delta as a whole system. Exposure values for the population and the ecosystem are also provided for the different flood types and probability scenarios for each township in the delta. Please note: The GDRI for the Ayeyarwady Delta was developed at the township level (PCode version 9.3 as of February 2023) and subsequently adjusted manually to align with the administrative boundaries used as reference for the 2014 Myanmar Population and Housing Census. As the designation and spatial delineation of administrative units in Myanmar are subject to regular changes, they may not accurately reflect current boundaries.
