Pesticide input datasets at 5 arcmin in China from 2001 to 2022

Spatially explicit datasets of pesticide inputs integrating 146 active ingredients across 12 crop systems in China from 2001 to 2022<br>## Description of the data and file structureThe dataset was developed through field surveys covering 1181 respondents and 12 crop systems and order-dependent relationship quantitation of crop-specific pesticide usage patterns, combined with multi-objective optimization to minimize provincial-level prediction errors, with official statistics serving as constraint conditions. This approach integrated crop-specific application trends, registration timelines, and spatial disaggregation to produce active ingredient (AI)-specific input estimates at 5-arcmin resolution from 2001 to 2022.<br>The dataset contains three parts of files: 1) 22 subsets, named as the year from 2001 to 2022, produce the geographically grided inputs of 146 AIs in China, 2）22 excel files, named as equation matrix_year (from 2001 to 2022), present parameter a, b, and c for calculation of AI-specific pesticide inputs in different crops from 2001 to 2022, and 3) field survey data contains crop-specific pesticide application rates.<br><br>## FilesThese files are composed of 1.83 gpkg excel files.2001.xlsx: 77086 rows, 45 columns2002.xlsx: 77086 rows, 64 columns2003.xlsx: 77086 rows, 81 columns2004.xlsx: 77086 rows, 94 columns2005.xlsx: 67611 rows, 119 columns2006.xlsx: 67611 rows, 131 columns2007.xlsx: 67611 rows, 135 columns2008.xlsx: 67611 rows, 137 columns2009.xlsx: 67611 rows, 141 columns2010.xlsx: 72053 rows, 144 columns2011.xlsx: 72053 rows, 144 columns2012.xlsx: 72053 rows, 144 columns2013.xlsx: 72053 rows, 145 columns2014.xlsx: 72053 rows, 146 columns2015.xlsx: 72053 rows, 146 columns2016.xlsx: 72053 rows, 146 columns2017.xlsx: 72053 rows, 146 columns2018.xlsx: 72053 rows, 146 columns2019.xlsx: 72053 rows, 146 columns2020.xlsx: 53581 rows, 147 columns2021.xlsx: 53581 rows, 147 columns2022.xlsx: 53581 rows, 147 columnsExcel files from equation_matrix_2001 to equation_matrix_2022: each excel file contains 12 spread sheets for 12 crop systems. Each spread sheet contain 32 rows of equations.<br><br>## Code/softwareThe code for producing pesticide input datasets was processed using the R software (version 3.6.2) and is available on GitHub (https://github.com/CauJane/CPI_model).<br>
