  • Sustainable phosphorus use — evaluating past patterns to inform future management

    Recycling waste from farming and mining could help improve the sustainable use of phosphorus, a recent study suggests. The study traced the stocks and flows of phosphorus over a 50 year period to reveal changing patterns of global phosphorus use. The results can be used to develop the sustainable management of phosphorus — a finite and critical resource — in the future. ...

  • Baker’s yeast wastewater has limited effect on groundwater when used for irrigation

    Untreated wastewater from the baker’s yeast industry can be used to irrigate crops without negatively affecting the chemical quality of the groundwater beneath, recently published research concludes. Although the wastewater increased concentrations of some groundwater contaminants in an area with a high water table, these levels would not pose a risk to human health even if this water was ...

  • Balancing food security and environmental quality in China

    In many ways, the evolution of Chinese agriculture over the past 40 years is a remarkable success story. Spurred by investments in research and government subsidies for fertilizers and other farm technologies, China now feeds 22% of the world’s population on just 9% of its total arable land.
