Dataset on irrigation subsidies and river flows in Chile, 1970–2019

This dataset compiles municipal-level information for Chile covering the period 1970–2019, resulting in 17,300 observations across 346 municipalities. It integrates data from three main sources: Hydrological and meteorological data from the Center for Climate Science and Resilience (CR2), including annual precipitation and river flow series derived from hydrometric and weather stations. Irrigation subsidies from the National Irrigation Commission (CNR), reporting 12,862 projects financed under Law N° 18,450 between 1987 and 2019. These subsidies are used as a proxy for the adoption of irrigation technology, given the absence of systematic records of fully private projects. Structural variables from the 2007 Agricultural and Forestry Census, including cultivated land, native forest, and forest plantations, which are relatively stable territorial characteristics. The dataset has been harmonized at the municipal level by aggregating hydrological and meteorological station data and georeferencing irrigation projects to municipalities. It includes both the raw annual series and treatment indicators used in the econometric analysis. Geographic coverage: 346 municipalities of Chile Temporal coverage: 1970–2019本数据集汇编了智利1970—2019年的市级层面信息，共覆盖346个市镇的17300条观测记录。数据集整合了三大核心来源的数据： 一是来自气候科学与韧性中心（Center for Climate Science and Resilience，CR2）的水文气象数据，包含由水文站与气象站观测得到的年降水量与河流径流序列； 二是国家灌溉委员会（National Irrigation Commission，CNR）的灌溉补贴数据，记录了1987年至2019年间依据第18450号法案资助的12862个灌溉项目。由于缺乏全私人项目的系统性记录，该补贴数据被用作灌溉技术采用的代理变量； 三是2007年农业与林业普查的结构变量数据，涵盖耕地、原生林与人工林面积，这类指标属于相对稳定的区域特征。 本数据集已完成市级层面的标准化整合：通过聚合水文气象站观测数据、将灌溉项目进行地理配准至对应市镇，同时包含原始年度序列与计量分析所用的处理指标。 地理覆盖范围：智利346个市镇 时间覆盖范围：1970—2019年
