•remove non-essential P inputs (e.g. detergents) •match P requirements more closely (precision agriculture)
•utilise legacy P stores Realign P inputs
•optimise input management •minimise runoff and erosion •strategic retention zones
Reduce P losses to water
•avoid wastage •improve utilization efficiency •adopt integrated production systems
Recycle P in bioresources
•recover P in societies' wastes •produce fertilizer substitutes
Recover P in wastes
•influence dietary choice •define end-user P requirements •re-connect crop and animal production systems
Redefine P in the food chain

Data quality & monitoring challenges
Data quality: trade > production > consumption > recycling
Unclear definitions & not enough detail in data
Public data is incomplete and inconsistent
Data gaps for waste flows & (new) recycling flows
Literature data mostly not recent and only specific base years
Trade databases not available for all products/materials
Data gaps requires data filling procedures & flow balancing
Industry data not publically available, sometimes commercially, but no peer reviewed
Uncertainties for most data unknown
Nutrient concentrations not monitored spatially & temporarily
From quantity to quality, from theory to practise

DONUTSS Data on Nutrients to Support Stewardship - workshop Ghent with science and important all stakeholders - EU Commission DG GROW support identify data needs to support decision making for industry & regulators define how and who to monitor & compare data
