Chinese agricultural production is key to achieve the country’s 2060 carbon neutrality target. Combining meta-analysis and life-cycle assessment, this study estimates the climate change mitigation potential of straw, biochar, and an integrated biomass pyrolysis and electricity generation system.
Global assessments of greenhouse gas emissions from nitrogen fertilizers show that production accounts for approximately one-third of total greenhouse gas emissions, with the remainder coming from the use phase. Intervention technologies at both the production and use phases could reduce up to 84% of global greenhouse gas emissions of synthetic nitrogen fertilizers by 2050.
Ad libitum energy intake was studied in relation to meal non-beverage energy density, protein content, eating rate and proportion of calories derived from hyper-palatable foods. Data were collected from 35 inpatient participants of two feeding studies lasting 28 continuous days including minimally and ultraprocessed food consumption.
Tropical blue food supply can be enhanced by small-scale octopus fisheries. Their catch methods and management approaches contribute to sustainable production and livelihoods.
This Analysis illustrates how nature-positive targets aimed at protecting biodiversity can be achieved at the scale of organizations. A canteen at one UK university college is used as a case study for the application of a four-step participatory approach comprising an estimation of food-related biodiversity impacts; definition of biodiversity targets; assessment of possible interventions; and exploration of different strategies.
