City-level panel of urban groundwater, foodsheds and urbanization for 875 Southeast Asian cities

It covers all 875 GHS-UCDB R2019A urban centres in the eleven Southeast Asian countries, holding 292.8 million residents in 2015. SEA_city_panel.csv is the principal file: 875 cities by 120 variables, containing every quantity reported in the associated manuscript.

These include reconstructed groundwater abstraction, water-supply and contamination-adjusted purification value, modelled arsenic hazard, foodshed rice production and self-sufficiency at 25 km and 100 km radii, flood and storm-surge exposure, elevation, and built-up area at 1975, 1990, 2000 and 2015. Superseded pre-posterior values are retained under reliance_prior_point for transparency. Also included: SEA_city_projection.csv (2030 and 2050 projections), SEA_reliance_posterior.csv (hierarchical Bayesian country reliance posterior), SEA_urban_gw_reliance_estimates.csv (the three input instruments the model reconciles), SEA_country_water_panel_1990-2025.csv (FAO AQUASTAT national accounts with provenance flags retained), kappa_sensitivity.csv (sensitivity of every arsenic-dependent result to the assigned Beta concentration), and reference tables for arsenic, published subsidence rates and prior valuation literature.
