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.

本数据集提供了由Hagenlocher等人（2018年）提出、专为缅甸伊洛瓦底江三角洲定制的全球三角洲风险指数（Global Delta Risk Index, GDRI），以及由Vogel等人（2024年）开发的人口与生态系统暴露度指标——该指标是系统评估脆弱性与多维度洪水风险的核心工具。我们将55项社会与生态系统脆弱性指标，与三角洲亚区域尺度下的暴雨洪水、河川洪水、海岸洪水的100年、500年、1000年一遇灾害情景及暴露度数据相结合。以乡镇为分析单元，可弥合全球与地方案例研究间的鸿沟，为整个三角洲系统的风险导向型发展提供兼具科学性与实践价值的决策参考。本数据集同时提供了伊洛瓦底江三角洲各乡镇针对不同洪水类型与概率情景的人口与生态系统暴露度数值。

请注意：伊洛瓦底江三角洲的GDRI最初以乡镇级尺度开发（采用2023年2月发布的PCode版本9.3），后经手动调整，以匹配2014年缅甸人口与住房普查所采用的行政边界。由于缅甸行政单元的命名与空间划分会定期调整，当前数据可能无法准确反映最新的行政边界。
