Summary: The study found that N2O emissions from anammox processes are a major challenge in full-scale application, but can be reduced by increasing the nitrogen loading rate. High N2O emissions were positively correlated with the count of denitrifying bacterium enrichment culture clone NOA 1 C10 and Defluviimonas denitrificans, while incomplete heterotrophic denitrification, attributed to the low chemical oxygen demand/nitrogen ratio, was considered the main cause of high N2O emissions during the startup period.

Summary: This paper comprehensively reviews the status of greenhouse gas (GHG) production and emission in wastewater treatment. It reveals that nitrous oxide (N2O) emission contributes significantly to the total GHG emissions, and emphasizes the importance of dissolved N2O and methane (CH4) in effluent for further GHG mitigation. Alternative integration systems, such as coupling denitrifying anaerobic methane oxidation with anammox process, are discussed as promising approaches for GHG mitigation. Moreover, strategies to manage N2O and CH4 as energy sources are demonstrated for offsetting carbon footprint in wastewater treatment and achieving net-zero GHG emission.

Summary: Inland waters serve an active role in the global carbon cycle by emitting large volumes of greenhouse gases. Research has highlighted the potential importance of small, artificial waterbodies like drainage ditches and constructed ponds as significant emission hotspots. Greenhouse gas emissions from these artificial waterbodies are positively related to nutrient status and are larger per unit area compared to natural systems, contributing to the global carbon cycle.

Summary: This study conducted field observation experiments for three years to compare the comprehensive benefits of different film mulching irrigation methods on greenhouse gas emissions, grain yield, water and fertilizer efficiency in maize fields. The results showed that drip irrigation under mulch (DM) had lower N2O emissions (32.46%), higher CH4 absorption (23.49%), and lower CO2 emissions (4.53%) compared to border irrigation under mulch (BM). Different environmental factors played varying roles in controlling greenhouse gas fluxes under the two treatments. Maize yield, irrigation water use efficiency (IWUE), and partial factor productivity of applied nitrogen (PFPN) were higher under DM by 17.85%, 17.90%, and 71.84% respectively, while the global warming potential (GWP) and greenhouse gas emission intensity (GHGI) under DM were lower by 6.65% and 20.79% respectively compared to BM. This research provides valuable insights into agricultural development in arid areas.

Summary: The rapid development of agricultural plastic greenhouses in China has had positive economic effects but also negative environmental impacts. This study analyzed the spatial and temporal evolution of these greenhouses and their greenhouse gas emissions from 2000 to 2020. It was found that the area covered by these greenhouses increased significantly, primarily concentrated in the North China Plain. The increase in greenhouse gas emissions was mainly attributed to the expansion of these greenhouses and the use of agricultural materials, particularly nitrogenous fertilizers and greenhouse construction materials.

Summary: With the development of the biogas industry in China, there is a large amount of by-product called biogas slurry. The static storage of biogas slurry, which is commonly used before applying it to land, can lead to nutrient decomposition and greenhouse gas emission. This study aimed to investigate the decomposition of nutrients, emission of greenhouse gases (CH4 and N2O), and phytotoxicity of biogas slurry under different temperatures. The results showed that higher temperature at 30 degrees C promoted the degradation of COD and had less toxicity to crops. CH4 was the dominant greenhouse gas emitted, and its emission was highest at 30 degrees C. Lower temperature reduced greenhouse gas emission but adversely affected the stabilization of organic matter and crop safety. These findings can be used to monitor environmental risk, evaluate maturity, guide irrigation schemes, and regulate the storage conditions of biogas slurry.

Summary: This study showed that intensifying traditional cropping systems with common vetch can lead to higher ecoefficiency, lower energy requirements, and increased economic returns and forage yield. Planting common vetch during the summer fallow period may be a productive and economically sound practice that has low energy requirements, offering potential benefits for agriculture under conditions of global environmental pollution and limited resources. Farmers should consider crop selection based on energy requirements, market values, and GHGs for profitable and eco-efficient incorporation of forage crops into cropping systems.

Summary: It was found that the mode of oxygen, carbon, and nitrogen supply determines the enrichment of the culture in specific populations, thus influencing the type of intracellular compounds preferentially accumulated. Coupled carbon and nitrogen feeding regime mainly selects for TAG producers, while uncoupled feeding leads to PHA or TAG production depending on the rate of carbon supply under specific aeration rates and feast and famine phases lengths.
