Summary
This study maps pesticide application rates across the European Union at 250m resolution. It integrates global data, crop maps, and official figures, providing crucial insights for environmental risk assessment.
Area of Science:
- Environmental Science
- Agricultural Science
- Geospatial Analysis
Background:
- Pesticide application data in the European Union lacks high spatial resolution.
- Accurate mapping is essential for understanding pesticide fate, transport, and environmental impact.
Purpose of the Study:
- To develop a high-resolution (250m) map of pesticide application rates across the European Union.
- To create a data product that aids in environmental risk assessment and understanding pesticide behavior.
Main Methods:
- Utilized global pesticide input estimates (PEST-CHEMGRIDS) as initial values.
- Adjusted estimates using a calibration dataset from agricultural pesticide use.
- Integrated data with high-resolution crop maps and EUROSTAT figures.
- Employed Maximum Likelihood estimation to account for data quality and uncertainty.
Main Results:
- Generated detailed spatial distributions of pesticide application rates for the EU.
- Provided a novel dataset with 250m spatial resolution.
Conclusions:
- The developed data product facilitates comprehensive evaluation of pesticide fate, transport, and biogeochemical transformations.
- This high-resolution mapping is vital for accurate environmental risk assessment of pesticides in the EU.
