Annual Pesticide Application Maps for 162 Active Ingredients

CEH Land Cover plus: Pesticides maps annual average pesticide applications across England, Wales and Scotland for 162 different active ingredients. It provides application estimates at a 1km resolution, averaged between 2012 and 2017, with units of kg active ingredient applied per year.

Use Cases

• Model environmental exposure to specific active ingredients like Acetamiprid or Azoxystrobin using 1km resolution application rates.
• Analyze spatial patterns of herbicide or fungicide usage across crop types identified in the underlying Land Cover Plus: Crops data.
• Assess uncertainty in pesticide application estimates for policy decisions using the provided uncertainty maps for each active ingredient.
• Correlate pesticide application rates (kg/km2/yr) with land cover changes or ecological survey data.

Strengths

• Covers 162 distinct active ingredients including herbicides, insecticides, molluscicides and fungicides.
• Provides data at a consistent 1km spatial resolution across England, Wales and Scotland.
• Includes uncertainty maps quantifying confidence levels for each active ingredient's estimated applications.

Limitations

• Data is an average from 2012-2017 and may not reflect current application practices or regulations.
• Resolution is at 1km squares, which may be too coarse for fine-scale local environmental impact studies.
• Relies on modeled estimates and survey data, introducing inherent estimation error.
