title: DESCONSIDERAR - Supplementary Material – Divergent Frameworks, Shared Challenges: A Comparative Analysis of National and State Water Security Plans in Minas Gerais, Brazil (Ferreira; Macedo; Magalhães Junior)

description: 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)**.
