The overlooked link between fossil fuel-derived sulfur and the production of phosphate fertilizers may lower agricultural productivity and harm global food security unless action is taken.
The assignment of foods to one of four categories proposed by the Nova framework may be challenging in the absence of information on how these foods were prepared and their specific composition. A three-step iterative approach can make the categorization process more efficient and transparent, thereby increasing the accuracy of Nova estimates.
This year’s World Metrology Day is themed around the global food system. Beyond the need for metrics that can capture complexity, this is an opportunity to reflect more broadly on the quantitative paradigm that largely underlies food systems research.
The latest report from the Intergovernmental Panel on Climate Change reminds us that unless mitigation and adaptation measures are implemented at the required pace, their costs will rise while their effectiveness will fall. Food systems are at the centre of this debate, offering opportunities for both.
