The spatial patterns of global soil potential nitrogen cycling were characterized using 4,032 observations from 398 published studies. The global soil nitrogen cycle shifts from conservative in forests to leaky in croplands, highlighting the importance of forests in the global nitrogen cycle and the need for further insights on nitrate retention in croplands.
The Russia–Ukraine war has impacted food access globally, but the exact drivers behind it and the broader consequences for human and environmental health are unclear. Through scenario analysis, this study assesses the relative importance of higher agricultural input prices and export disruption to food access, and estimates undernourishment and cropland expansion.
This study uses arable soils subjected to consistent management for over 160 years to understand the influence of organic matter on arable soil nitrogen metabolism. The nonlinear and systems-level approach shows that important increases in nutrient-use efficiency can be achieved to improve soil organic carbon stocks and reduce N2O emissions.
Estimates of greenhouse gas emissions associated with feeding the world population rarely account for specific nutrient gaps. This study applies a composite indicator of emissions intensity of nutrient production to calculate non-CO2 emissions of closing the global dietary gaps for energy, protein, iron, zinc, vitamin A, vitamin B12 and folate in 2030 under five climate-friendly scenarios.
Immortalized chicken fibroblasts grown in serum-free media yield up to 36% w/v. Direct transdifferentiation generates adipocytes that, when blended with extruded soy protein, produce cultured chicken comparable with chicken breast.
Integrated structural and technological changes across the Chinese pork supply chain can improve production and meet demand while reducing phosphorous and nitrogen losses.
Higher number of markets, nutrient content, and overall supply coupled with lower retail prices and volumes make usipa more accessible than chambo to Malawians across all regions, particularly for rural consumers.
A spatiotemporal quantification of Fusarium head blight (FHB) mycotoxins in European food and feed wheat highlights the omnipresence of deoxynivalenol and increasing detection of other FHB mycotoxins. These potential health and economic costs emphasize the need to monitor FHB mycotoxin outbreaks and to understand what is driving this change, so that we can develop appropriate mitigation strategies.
Whether, how and to what extent integrating crop production, livestock production and bioenergy systems can enhance the sustainability of specialized farming remains poorly understood at downscaled regional levels. This study quantifies life cycle impacts of agricultural integration in China, including bioenergy provision.
A whole life cycle perspective demonstrates that rearing ruminants that utilize human-inedible biomass, instead of monogastric livestock that require grain for feed, can shift cropland demand from feed to food production.
The demand for dairy produce is growing alongside concerns about the impact of intensive dairying on water quality due to nutrient loss. Using observational and modelled data, this study compares systems with different outdoor livestock grazing times, flagging combinations that could minimize phosphorus and nitrogen losses.
Nanotechnology has the potential to increase the net revenue from agricultural products and alleviate the environmental impact of conventional fertilizers and pesticides. Further improving the efficiency of nanoformulations is necessary for their wide adoption.
Herring, sardine and anchovy are the cheapest fish species in many low- and middle-income countries, with <20% of small pelagic catch sufficient to meet the recommended fish intakes for young children living near water in sub-Saharan Africa.
A database from a survey of farmers, published articles and statistical yearbooks was developed to map crop- and county-specific yields, farm inputs, reactive N losses and greenhouse gas emissions in China. Optimized crop distributions combined with improved management are estimated to improve crop productivity and decrease farm inputs and environmental costs.
Promoting higher-than-historical adoption rates of improved Bos taurus × Bos indicus crosses is essential to meet Tanzania’s Dairy Development Roadmap targets and achieve dairy self-sufficiency by 2030.
The Russia–Ukraine war has disrupted global food supply chains and driven food prices up in many parts of the world. This study applies a spatially explicit modelling approach to estimate the resilience and environmental co-benefits of a transition towards the EAT-Lancet’s planetary health diets across Europe.
The exact contribution of food systems to air pollution is unknown. On the basis of the European Commission’s EDGAR-FOOD database, a global emission inventory of air pollutants from the food systems, this study quantifies historic emissions of major pollutant compounds at each stage of the food supply chain at country level.
Feeding industrial hemp silage affected feed intake, milk yield, respiratory and heart rates, and behaviour of dairy cows. Transfer of cannabinoids from feed to milk was investigated with liquid chromatography–tandem mass spectrometry and toxicokinetic computer modelling, and potential exposure to consumers explored.
