Supplementary Materials – Article Submission to RBRH Author: Matheus Vinícius Ferreira; Diego Rodrigues Macedo; Antônio Pereira Magalhães JuniorArticle Title: Divergent Frameworks, Shared Challenges: A Comparative Analysis of National and State Water Security Plans in Minas Gerais, Brazil Date: August 2025 This folder contains supplementary material related to the manuscript submitted to the Brazilian Journal of Water Resources (RBRH). It includes: - An Excel spreadsheet with the original variables used in the construction of the ISH and IGP indices (prior to spatial aggregation), - Three figures illustrating the statistical correlation between ISH and IGP, - Five shapefiles used in the spatial analysis of water security. -------------------------------------------------------------1. Excel File------------------------------------------------------------- - ISH_PMSH_Variables.xlsx → Spreadsheet containing the **original variables** used in the construction of the Water Security Index (ISH) and in the PMSH prioritization analysis via the IGP. These data represent indicator-level values **before municipal aggregation** and are organized by original analytical units. -------------------------------------------------------------2. Figures------------------------------------------------------------- - ISH_IGP_Correlation_Mean.jpg → Scatter plot showing the correlation between the **mean** values of the ISH and IGP indices. Equation: y = 0.0204x + 3.8775 R² = 0.0057 - ISH_IGP_Correlation_Median.jpg → Scatter plot showing the correlation between the **median** values of the ISH and IGP indices. Equation: y = 0.0156x + 3.9425 R² = 0.0033 - ISH_IGP_Correlation_Mode.jpg → Scatter plot showing the correlation between the **mode** values of the ISH and IGP indices. Equation: y = 0.0507x + 3.7813 R² = 0.0328 -------------------------------------------------------------3. Shapefiles------------------------------------------------------------- Each folder contains a complete set of shapefile components (.shp, .shx, .dbf, .prj). All spatial layers are projected in **SIRGAS 2000 (EPSG: 4674)**. - /ISH_2017/ → Original ISH values for the year 2017, calculated and mapped by **ottobacias**. - /ISH_2035/ → Projected ISH values for the year 2035, by **ottobacias**. - /ISH_standardized/ → Standardized ISH values **converted to the municipal scale** for comparative analysis. - /IGP_standardized/ → Standardized IGP values **converted to the municipal scale**, representing PMSH priority classification. - /PMSH_IGP_components/ → Spatial layers of the IGP index and its components used in the PMSH, represented by **aggregated planning units (Unidades Agregadas)**. ------------------------------------------------------------- All data and figures are original and were used to support the spatial and statistical analyses presented in the manuscript.
