Air Quality Demand Layer for Slurry Infrastructure Grant Round 1 in England

A spatial dataset identifies priority areas in England for improving air quality to support the Slurry Infrastructure Grant launched in October 2022. It was created by the Joint Nature Conservation Committee in consultation with Defra air quality specialists. The layer highlights Sites of Special Scientific Interest sensitive to ammonia emissions that exceed critical levels, buffered by 2 km.

Use Cases

• Prioritizing grant applications based on proximity to sensitive ecological sites.
• Mapping areas with high ammonia pollution demand for environmental planning.
• Analyzing spatial overlap between agricultural infrastructure and protected sites.

Strengths

• Created in consultation with an expert group of Air Quality specialists across Defra and its associated Arms-Length Bodies.
• Identifies specific Sites of Special Scientific Interest (SSSIs) with known features sensitive to ammonia emissions.
• Uses a defined 2 km buffer to create priority areas from identified sites.

Limitations

• Original dataset features have been heavily altered and none of the original attributes have been retained.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
