Summary
This paper examines the interconnections between phosphorus stewardship and climate change mitigation across China's fertiliser value chain. As suggested by the title, the authors analyse how improved phosphorus management—from production efficiency through to optimised field application—might reduce agricultural greenhouse gas emissions whilst enhancing nutrient use efficiency. The work appears to synthesise evidence from multiple supply chain stages to identify co-benefits and potential trade-offs in pursuing sustainable phosphorus and climate goals simultaneously.
UK applicability
Whilst focused on China's specific agricultural context and fertiliser infrastructure, the supply-chain systems approach and the concept of identifying synergies between phosphorus efficiency and emissions reduction may inform UK policy discussions on sustainable nutrient management and farm-level carbon accounting. However, differences in farming scale, regulatory environment, and phosphorus sources mean direct adaptation would require localisation.
Key measures
Greenhouse gas emissions intensity; phosphorus use efficiency; phosphorus losses; supply chain carbon footprint across production and application phases
Outcomes reported
The study examined synergies between sustainable phosphorus use practices and greenhouse gas emissions reduction across the entire phosphorus supply chain, from fertiliser production through agricultural application in China. It assessed how phosphorus management interventions might simultaneously address nutrient efficiency and climate mitigation objectives.
