Diverse development paths among cities within an urban agglomeration can lead to uneven changes in their agricultural production scale, which reshape the inter-city food supply patterns and the spatiotemporal characteristics of nitrogen (N) pollution from the food system. Here, using Guangdong–Hong Kong–Macao Greater Bay Area of China as a case, we found a substantial decrease in N use efficiency of crop production from 45.2% to 29.3% during 1989–2007, along with a growing level of concentration of food N production in less-urbanized cities. From 1989 to 2018, 12.3% to 42.2% of total N pollution in food production became embedded in inter-city trade, leading to aggregation of N pollution in peripheral cities with relatively low levels of economic development. We suggest that protection and intensification of cropland from urban encroachment, as well as enhancing the economic and technical synergies among cities, can serve the sustainable transition of the food system with coordinated N pollution mitigation. The food system of urban agglomeration undergoes continuous transitions and poses changing pressure to the environment, especially in terms of nitrogen (N) pollution. This study highlights the decreased N use efficiency and intensified local N pollution in the context of uneven agricultural contraction in urban agglomeration and reveals how cities can leverage synergies for coordinated N pollution mitigation.

Greenhouse cultivation has been expanding rapidly in recent years, yet little knowledge exists on its global extent and expansion. Using commercial and freely available satellite data combined with artificial intelligence techniques, we present a global assessment of greenhouse cultivation coverage and map 1.3 million hectares of greenhouse infrastructures in 2019, a much larger extent than previously estimated. Our analysis includes both large (61%) and small-scale (39%) greenhouse infrastructures. Examining the temporal development of the 65 largest clusters (>1,500 ha), we show a recent upsurge in greenhouse cultivation in the Global South since the 2000s, including a dramatic increase in China, accounting for 60% of the global coverage. We emphasize the potential of greenhouse infrastructures to enhance food security but raise awareness of the uncertain environmental and social implications that may arise from this expansion. We further highlight the gap in spatio-temporal datasets for supporting future research agendas on this critical topic. Greenhouses are quickly proliferating in response to the world’s increasing demand for food, but information on their precise location, distribution and extent remains limited in many countries. This Analysis combines global very-high-resolution satellite imagery and artificial intelligence to address this knowledge gap, showing a dramatic increase in greenhouse coverage in the Global South.

Inland recreational fishing is primarily considered a leisure-driven activity in freshwaters, yet its harvest can contribute to food systems. Here we estimate that the harvest from inland recreational fishing equates to just over one-tenth of all reported inland fisheries catch globally. The estimated total consumptive use value of inland recreational fish destined for human consumption may reach US$9.95 billion annually. We identify Austria, Canada, Germany and Slovakia as countries above the third quantile for nutrition, economic value and climate vulnerability. These results have important implications for populations dependent on inland recreational fishing for food. Our findings can inform climate adaptation planning for inland recreational fisheries, particularly those not currently managed as food fisheries. Harvest from inland recreational fisheries are estimated, demonstrating the importance of this food source for nutrition and economic value in food systems that are vulnerable to climate change.

Estimates of the nutritional value of recreational inland fisheries highlight their importance for aquatic food access and vulnerability to climate change. Yet, communicating the importance of data-poor natural resource sectors remains challenging, particularly when defining sustainable development priorities.

The intensification of livestock farming and related global trade are increasingly linked to the expansion of endemic bacterial pathogens, including zoonotic transfers to people. To preserve food security and public health, it is imperative to find measures that counter this trend.

Salmonella enterica causes severe food-borne infections through contamination of the food supply chain. Its evolution has been associated with human activities, especially animal husbandry. Advances in intensive farming and global transportation have substantially reshaped the pig industry, but their impact on the evolution of associated zoonotic pathogens such as S. enterica remains unresolved. Here we investigated the population fluctuation, accumulation of antimicrobial resistance genes and international serovar Choleraesuis transmission of nine pig-enriched S. enterica populations comprising more than 9,000 genomes. Most changes were found to be attributable to the developments of the modern pig industry. All pig-enriched salmonellae experienced host transfers in pigs and/or population expansions over the past century, with pigs and pork having become the main sources of S. enterica transmissions to other hosts. Overall, our analysis revealed strong associations between the transmission of pig-enriched salmonellae and the global pork trade. By analysing the genome of over 9,000 pig-associated isolates, this study shows that modernized agricultural systems have favoured the acquisition of antimicrobial resistance genes, population expansion and global transmission of pig-enriched Salmonella over the past century.
