Data and codes availability for "Age, climate and economic disparities drive the current state of global dam safety"

This repository contains the required information to reproduce the findings associated to: Moreno-Rodenas A., Mantilla J.D., Valero D. (2025) "Age, climate and economic disparities drive the current state of global dam safety", Nature Water. The file is structured as follows: .\scripts \SurvivalAnalysis_sub_sh.ipynb: Python scripts to replicate the survival analysis performed on the World's large dam failures. \PoissonBin_model_dams.ipynb: Python scripts to replicate the estimation of the number of future failures based on a Poisson binomial distribution. \Climate_fullWRD_NF.ipynb: Python scripts to replicate the crossing of failure statistics and climate zones. .\datasets \DamFailures_2018_2023.xlsx: Complementary failures in the period 2018-2022 to complete the analysis (1900-2022). This dataset has been collected by the authors and contains the location of failures, their context (EF: Extreme Floods, F:Floods, UF:Unusual Floods, War, pipping) and technical failure mode (OT: Overtopping, structure, liquefaction, breached, piping), along with characteristics of the dams (TE - Embankment dam, PG: Concrete dam). \GDP_ppp_WRD_comp_2018.xlsx: Gross Domestic Product Purchase Parity Power per capita per country as per 2018 in int USD. Extracted from the World Bank public data repository. In order to fully run the scripts, the following publicly available (yet under paywall) datasets must be acquired: 1- WRD_export_registre22_8_2024.xlsx: Dataset consisting of the world register of dams dataset from ICOLD (version updated 2024). This material is available upon purchase (publicly available) from the ICOLD webpage https://www.icold-cigb.org/GB/world_register/database_presentation.asp 2- ICOLD_failures_geor_sh_updated2023.xlsx: Dataset containing large dam failures registered in history for dams built between 1900 - 2022. This is composed of two sources, the failure records provided by ICOLD (version updated 2019). Publicly available upon purchase as ICOLD Bulletin 188 (https://www.icold-cigb.org/GB/publications/bulletins.asp), and the \DamFailures_2018_2023.xlsx contained in this repository.
