Estimated Annual Agricultural Pesticide Use for USA48 2000 to 2019 (gridded maps at 250-m resolution) (Q6689800)

Estimated low and high pescticide uses based on census data for USA48, provided for the cropland mask at 250-m spatial resolution. The original USGS maps are only available as PNGs, so we have prepared here a code to rasterize the values and produce GeoTIFFs. For cropland mask we use the National Land Cover Database (NLCD). All processing is fully documented in: https://github.com/Envirometrix/pesticide-use-USA48. All maps are projected in the EPSG:5070. Description of the layers: croplands_20**_250m.tif = cropland mask (0100%) estimated based on NLCD. GLYPHOSATE_EPEST.HIGH.KG.KM2_20**_250m.tif = estimated pesticide use per county (high estimate) expressed in kg/km-square. diff.GLYPHOSATE_EPEST.HIGH.KG.KM2_250m.tif = annual difference in pesticide use from 2000 to 2019; Disclaimer: this code is under construction and USGS makes is clearly available that there are some limitations to this data: These estimates are made by using projected county crop acres from the previous Census of Agriculture and are expected to be revised upon availability of updated crop acreages in the following Census of Agriculture. The files do not include pesticide use estimates for California. Data for California are obtained from the online Department of Pesticide Regulation-Pesticide Use Reporting (DPR-PUR) database and are typically not available at the time the preliminary pesticide use estimates are generated for the rest of the U.S. Pease have in mind these limitations when using these maps for further modeling.
