As an electrogenic bacterium, Geobacter plays a crucial role in the geochemical cycles of arable soil. However, little is known about the existence of Geobacter and its impact factors in paddy soil and purple soil. We determined Geobacter in paddy soil and purple soil in Sichuan Basin, China. The data reveal that soil pH in arable soils is the main...

To achieve the goal in the Paris Agreement of limiting mean global temperature rise to 1.5 �C, total anthropogenic radiative forcing (RF) should be reduced from current 2.7 to around 1.9 W m�2 . A newly developed RF-based climate footprint (RFCF) indicator, which quantifies the additional contribution to RF associated with current and historical em...

Aim: This study evaluated phylogenetic diversity, plant growth promotion capacity, antifungal activity and biocontrol potential of culturable actinobacterial endophytes isolated from medicinal plant Aconitum carmichaelii Debeaux. Methods and results: Isolation of actinobacteria from healthy A. carmichaelii plants was carried out on six different...

Medicinal plants harbor tremendously diverse bacterial endophytes that maintain plant growth and health. In the present study, a total of 124 culturable bacterial endophytes were isolated from healthy Aconitum carmichaelii Debx. plants. These strains were clustered into 10 genera based on full-length 16S rDNA sequences, among which Bacillus and Pse...

Soil microorganisms play pivotal roles in element biogeochemical cycling and ecological functions in wetland ecosystem, which may affect global climate change. Variations in biotic and abiotic factors are known to affect soil microbial diversity, community structure and the corresponding functions. However, the relative importance of these biotic a...

Aconitum carmichaelii Debx. is a famous medicinal plant rich in alkaloids and widely used to treat various human diseases in Asian countries. However, southern blight caused by Sclerotium rolfsii severely hampered the yield of A. carmichaelii . Beneficial microbe-based biological control is becoming a promising alternative and an environmentally fr...

Increasing crop productivity and minimizing greenhouse gas emissions from paddy fields are increasingly receiving attention. Slag application not only can maximize the use of solid wastes as beneficial resources for agricultural production, but it also reduces greenhouse gas emissions. In order to determine the most effective slags as soil amendmen...

Aconitum carmichaelii Debx. is famous for the bioactive aconitum alkaloids as traditional Chinese medicine. Endophytic bacteria play vital roles in plant growth, health, and the production of secondary metabolites such as alkaloids. In this study, we employed 16 S rRNA amplicon high‐throughput sequencing to determine the root endophytic bacterial c...

Large quantities of semiconductor minerals on soil surfaces have a sensitive photoelectric response. These semiconductor minerals generate photo-electrons and photo-hole pairs that can stimulate soil oxidation–reduction reactions when exposed to sunlight. We speculated that the photocatalysis of semiconductor minerals would affect soil carbon cycle...

How to achieve China's “Carbon Peak” and “Carbon Neutrality” targets in the agriculture sector is crucial but still remains challenging. This study thus aims to assess the effects of crop rotations and farm size with optimized nitrogen (N) rate on carbon footprint (CF), emergy and economic benefits to promote agricultural transformation in the Nort...

China’s potato policy, introduced to improve food security, shows that substituting staples with alternative crops, though rarely the focus of dietary advice for planetary health, can also reduce the environmental impacts of food.

Over the past decades, China’s rice production area has experienced a substantial change in spatial distribution that has exacerbated national freshwater scarcity. To support the development of guidelines for sustainable water use in rice cropping, this study explores the potential for achieving a downscaled freshwater use boundary with high spatia...

Various environmental challenges are rapidly threatening ecosystems and societies globally. Major interventions and a strategic approach are required to minimize harm and to avoid reaching catastrophic tipping points. Setting evidence-based priorities aids maximizing the impact of the limited resources available for environmental interventions. Foc...

Freshwater use is recognized as one of the nine planetary boundaries. However, water scarcity is a local or regional phenomenon, meaning that the global boundary must be spatially downscaled to reflect differences in water availability. In China, as in most countries, irrigation is the major freshwater user, closely linking food security to the fre...

In recent decades, China’s crop production experienced a spatial shift, and this shift may significantly influence the national water resources due to the geographical mismatch between water resources and cropland. By applying the widely applied AquaCrop model, this study quantified the impact of grain crop (rice and maize) expansion in northeaster...

Water shortage is a critical constraint limiting China's capacity for food security. To provide evidence supporting environmentally sustainable water use in food production, this study compared irrigation water productivities (IWPs) and water-scarcity footprints (WSFs) for China's wheat production at high spatial resolution. Contrary to previous wa...

The growing demand for geospatial application of environmental models has led to the development of tools for conducting simulations spatially. A model-independent and open-source tool named Geospatial Simulation (GeoSim) has been developed previously. Based on previous applications at field scale, this study advances GeoSim application for nationa...

Increased application of nitrogen (N) and phosphorus (P) fertilizer has significantly improved crop yields and food security in China over the past several decades. However, this has also led to serious problems of aquatic eutrophication in inland and coastal waters. This study analyzed N and P losses from major cropping systems across China using...

Beijing is one of the most water-stressed regions in the world. Reducing agricultural water use has long been the basis of local policy for sustainable water use. In this article, the potential to reduce the life cycle (cradle to gate) water footprints of wheat and maize that contribute to 94% of the local cereal production was assessed. Following...

Changing precipitation patterns and shortages of surface and groundwater in important cropping regions pose a serious threat to China’s future food security. This paper presents a comprehensive analysis of water used for food production over the period 1998–2010 with a view to identifying pathways for achieving the national target of 580 million to...

In the process of supply chain management, the environmental impact is one important concern. Carbon footprint is a popular metric to quantify a products greenhouse gas (GHG) emissions, and assist supply chain management. In this paper, carbon footprints were calculated for three common milk products, 180 g Yogurt, 250 mL Fluid milk and 400g Skim m...

Beijing is situated in water-scarce northern China, where there is a history of policies aimed at constraining local agricultural water use to meet the increasing urban water demand. This has led to a change in local crop production and subsequent effects in terms of the importation of cereals and vegetables grown in other parts of China. The dilem...

Adequate freshwater supply has become an issue of increasing local and international concern. Reducing water use in agriculture, which is the largest water using sector of the economy, is both important and urgent. The aim of this paper was to quantify how recent cropping pattern changes have influenced water resources in the great Beijing metropol...

Hoekstra and Mekonnen (1) offered a comprehensive assessment of global water use from the perspective of national production, consumption, and international trade. This study highlighted the often neglected fact that it is the demand for everyday goods and services that places the most pressure on the world’s freshwater systems. As such, strategies...
