Livestock production poses a threat to water quality worldwide. A better understanding of the contribution of individual livestock species to nitrogen (N) pollution in rivers is essential to improve water quality. This paper aims to quantify inputs of dissolved inorganic nitrogen (DIN) to the Yangtze River from different livestock species at multiple scales and explore ways for reducing these inputs through coupling crop and livestock production. We extended the previously developed model MARINA (Model to Assess River Input of Nutrient to seAs) with the NUFER (Nutrient flows in Food chains, Environment, and Resource use) approach for livestock. Results show that DIN inputs to the Yangtze River vary across basins, sub-basins, and 0.5° grids, as well as across livestock species. In 2012, livestock production resulted in 2000 Gg of DIN inputs to the Yangtze River. Pig production was responsible for 55–85% of manure-related DIN inputs. Rivers in the downstream sub-basin received higher manure-related DIN inputs than rivers in the other sub-basins. Around 20% of the Yangtze basin is considered as a manure-related hotspot of river pollution. Recycling manure on cropland can avoid direct discharges of manure from pig production and thus reduce river pollution. The potential for recycling manure is larger in cereal production than in other crop species. Our results can help to identify effective solutions for coupling crop and livestock production in the Yangtze basin.

“…Over recent decades, the decoupling of crop and livestock production has raised the mineral N input but decreased the organic manure share in fertilizer application [54] . In this context, large-scaling farming may promote the integration of crop and livestock production [53] , thus increasing the nutrient use efficiency and decreasing nutrient emissions to water in the agricultural systems [55] . In other words, large-scale farming reduced soil acidification risks by improving nutrient management strategies, such as reducing acidifying sources (NH4 + fertilizer) and adding acid buffering elements (organic fertilizers).…”

HIGHLIGHTS• Large farms had the highest average yield and the least yield variation.• Greater plant density and optimized nutrient input occurred on large farms.• Substituting organic N for mineral fertilizers prevented soil acidification.• Large-scale farming had lower soil acidification but higher risk of P losses.• Large-scale farming benefits sustainable soil management and banana production.

“…e state attaches great importance to the integration of the agricultural industry chain and the coordinated development of the ecological environment. From 2012 to 2019, the green development pattern of agriculture has gradually formed [2], which better adapts to the miniaturization, quality, and re nement characteristics of consumer demand [3,4]. Strengthening the construction of the whole agricultural industry chain and green transformation and upgrading, ensuring the e ective supply of high-quality agricultural products and meeting the requirements of ecological environment quality, will become the main direction of green and high-quality agricultural development in China.…”

The green development of the entire agricultural industry chain is not only an important way to enhance the competitiveness of agricultural products and promote the value-added of the agricultural industry but also an inevitable choice to improve the efficiency of resource utilization and ensure sustainable economic development from the perspective of the ecological environment. This paper defines the connotation and characteristics of the green development of the whole agricultural industry chain and deeply analyzes the development status, major challenges, and feasible paths of the whole agricultural industry chain in China. It has built a whole industry chain development model of “Internet + modern agriculture” and proposed a decentralized agricultural data management system based on the IoT to solve the problem of untraceable of traditional agricultural products and other data. The agricultural IoT system is designed with a unique blockchain double-chain structure, using the global hash chain and the mutual verification between the transaction chains in each partition. It proposes the PMCP protocol, which improves the performance of the system by producing blocks in parallel for several consensus groups in each consensus cycle. The experimental results show that the proposed model is queryable, traceable, and trustworthy for whole-life agricultural data, and the proposed model outperforms other schemes in terms of throughput and delay.
