Exploring wastewater nitrogen and phosphorus flows in urban and rural areas in China for the period 1970 to 2015
China has experienced rapid population growth and increasing human N and P discharge from point sources. This paper presents a new spatial and temporal model-based, province-scale inventory of N and P…
Inland Waters Increasingly Produce and Emit Nitrous Oxide
Nitrous oxide (N 2 O) is a long-lived greenhouse gas and currently contributes ∼10% to global greenhouse warming. Studies have suggested that inland waters are a large and growing global N 2 O source…
Effects of Nitrogen Emissions on Fish Species' Richness across the World’s Freshwater Ecoregions
The increasing application of synthetic fertiliser has tripled nitrogen (N) inputs over the twentieth century. N enrichment decreases water quality and threatens aquatic species such as fish through…
Hindcasting harmful algal bloom risk due to land-based nutrient pollution in the Eastern Chinese coastal seas
Harmful algal blooms (HABs) have been increasing in frequency, areal extent and duration due to the large increase in nutrient inputs from land-based sources to coastal seas, and cause significant…
Cost-effective mitigation of nitrogen pollution from global croplands
Based on a meta-analysis of 1,521 worldwide field observations, 11 key measures were identified that reduce global nitrogen losses from croplands to air and water by 30–70%, while increasing crop…
From planetary to regional boundaries for agricultural nitrogen pollution
Excessive agricultural nitrogen use causes environmental problems globally, to an extent that it has been suggested that a safe planetary boundary has been exceeded.
Halving nitrogen waste in the European Union food systems requires both dietary shifts and farm level actions
This paper analyses options to halve nitrogen losses to the environment by 2030, which is a target of the Farm to EU Fork Strategy. We found that a combination of interventions to (a) increase farm…
Establishing long-term nitrogen response of global cereals to assess sustainable fertilizer rates
Insight into the response of cereal yields to nitrogen fertilizer is fundamental to improving nutrient management and policies to sustain farm economy and food sufficiency with minimum nitrogen…
Phosphorus for Sustainable Development Goal target of doubling smallholder productivity
The supply of phosphorous is crucial to food security. Future phosphorous management will therefore play an important role in achieving Sustainable Development Goal 2 (SDG2, zero hunger). However, in…
What drives the ecological quality of surface waters? A review of 11 predictive modeling tools
What policy is needed to ensure that good-quality water is available for both people’s needs and the environ-ment? The EU Water Framework Directive (WFD), which came into force in 2000, established a…
