Pig production contributes considerably to land use and greenhouse gas (GHG) and reactive nitrogen (Nr) emissions. Land use strategies were widely proposed, but the spillover effects on biological flow are rarely explored. Here, we simultaneously assessed the carbon (C), nitrogen (N), and cropland footprints of China’s pig production at the provinc...
The over-use of antibiotic growth promoters (AGPs) in livestock husbandry may have contributed on creating environmental and human health hazards. A number of acidifiers as alternative to AGPs, has been added into diets to prevent the post-weaning syndrome in pigs. However, the effect of feed acidifiers on growth performance of pigs is not consiste...
Nearly half of global pork production and consumption occurs in China, but the transition towards intensification is associated with worsening environmental impacts. Here we explore scenarios for implementing structural and technological changes across the pork supply chain to improve environmental sustainability and meet future demand. Following t...
Our food system drives global environmental change, and differences in environmental concerns of consumers may cause negative environmental 'spillover effects' in less concerned countries. While food system transformation is increasingly recognised as crucial for mitigating such negative environmental spillovers, possible unintended negative enviro...
Low-protein feeding is a strategy used to decrease nitrogen excretion and ammonia (NH3) emissions from animal manure, while maintaining productivity. The optimal protein content depends on many factors, including the type, age, and production level of the animal, as well as the availability, composition, and digestibility of the feed ingredients. F...
Soil fertility of cropland depended partly on the local availability of livestock manure in history. The relationship between soil fertility and livestock density became entangled through spatial decoupling of livestock and crop farms. Understanding this relationship is important for spatial planning of livestock farms and for manure management. Th...

Global dairy production contributes a relatively large share of the total emissions of nitrogen (N) and phosphorus (P) to air and water bodies, which are a concern. However, there are large differences among dairy farming systems in performance, and these differences are not well understood. This relates especially to emerging market econom...
The rapid specialization of livestock production in China has contributed to spatially decoupled crop and live-stock production, leading to various environmental pollution issues. Some regional agro-environmental policies have recently promoted the coupling of specialized crop and livestock farms through cooperation. However, the environmental and...
Improving manure management is essential to actualise a more circular economy in agro-ecosystems. However, the drivers of and barriers to improving manure management and recycling are not well understood. We report farmers' perceptions of manure management techniques on dairy and poultry farms, with a focus on anaerobic digestion, solideliquid sepa...
