Owner: Defra

Target date: 31 December 2038 (final); December 2030 (interim: 12% nationally)

Metric: Nitrogen, phosphorus, and sediment loads in watercourses from agricultural sources; tracked via Environment Agency’s National Agriculture Programme.

Status: at-risk

Delivery history

  • [December 2025] Agriculture Water Quality Target Delivery Plan published. Four-pillar framework confirmed: regulatory (12%), voluntary ELM (3%), land use change (11%), innovation (14%).
  • [January 2026] SFI 2026 changes announced — reduces number of actions; reviews payment rates for high-uptake actions that take land out of production. Pillar 2 (voluntary ELM) at risk.
  • [2026-04-15] Status: at-risk. Pillar 2 contribution (3%) is directly threatened by SFI changes. Innovation pillar (14%) depends on trial completions 2026-2028.
