Climatic and socioeconomic dataset for drought-related emergency decrees in Western Bahia, Brazil (2013–2022)

This dataset was developed within the BiomasBR project to support climate risk assessment initiatives, including applications in the AdaptaBrasil platform. It contains climatic and socioeconomic variables associated with drought conditions and drought-related emergency decrees in municipalities in the western region of Bahia, Brazil, covering the period from 2013 to 2022.

The dependent variable consists of municipal records of emergency decrees related to droughts and dry spells, obtained from the Digital Atlas of Disasters. Independent variables include climatic indicators such as precipitation (CHIRPS), consecutive dry days (CDD), SPEI, and ENSO (ONI), as well as socioeconomic indicators including GDP, population, and social vulnerability metrics from IBGE and IPEA.

The dataset incorporates temporal lag effects by linking climatic conditions from current and preceding periods to the occurrence of emergency decrees. It is suitable for applications in climate risk analysis and the development of statistical and machine learning models for predicting drought-related impacts.

本数据集由BiomasBR项目研发，旨在支撑气候风险评估相关工作，包括在AdaptaBrasil平台中的应用。数据集涵盖2013至2022年巴西巴伊亚州西部各市政辖区的气候与社会经济变量，关联干旱状况及与干旱相关的紧急政令信息。

因变量为源自灾害数字地图集（Digital Atlas of Disasters）的各市政干旱及干期相关紧急政令记录。自变量则包含多类气候指标：降水数据（CHIRPS）、连续无雨日数（CDD，Consecutive Dry Days）、标准化降水蒸散指数（SPEI，Standardized Precipitation Evapotranspiration Index）以及厄尔尼诺南方涛动（ENSO，El Niño-Southern Oscillation）的海洋尼诺指数（ONI，Oceanic Niño Index）；同时涵盖社会经济指标，包括国内生产总值（GDP，Gross Domestic Product）、人口数据，以及巴西地理与统计研究所（IBGE，Instituto Brasileiro de Geografia e Estatística）和巴西应用经济研究所（IPEA，Instituto de Pesquisa Econômica Aplicada）发布的社会脆弱性指标。

本数据集通过将当前及前期的气候状况与紧急政令的发生情况相关联，纳入了时间滞后效应。该数据集适用于气候风险分析，以及干旱相关影响预测的统计与机器学习模型开发工作。
