Summary: This study investigated the effects of elevated CO2 (eCO2) and different rice cultivars on CH4 and N2O emissions in Chinese subtropical rice systems. The results showed that eCO2 increased rice yield and decreased CH4 and N2O emissions. The strongly responsive cultivars had lower emissions and were associated with higher soil Eh and [O-2] levels.

Summary: Understanding the roles of natural drivers and anthropogenic activities in greenhouse gas emissions of arable fields is crucial for adopting appropriate agricultural management practices. This study found that the impact of mouldboard ploughing and no-tillage on CO2 emissions did not differ significantly over a full year, but varied in different sub-periods. No-tillage had a higher impact on both CO2 and N2O emissions compared to mouldboard ploughing.

Summary: Rubber plantations cover a vast area globally, and introducing leguminous shrubs can help reduce CO2 and CH4 emissions while increasing N2O emissions, ultimately improving soil environments. As trees in rubber plantations age, there is a significant decrease in annual emissions of CO2, N2O, and CH4, with rubber-leguminous shrub systems showing potential for enhancing soil organic carbon sequestration.

Summary: Greenhouse gas emissions from agricultural soils can accelerate climate change. This study examines the short-term effects of different pig slurry application techniques on soil greenhouse gas and ammonia emissions under different irrigation amounts. The study finds that there is an increase in emissions after slurry application, but the difference between spreading and injection techniques is not significant. Dry conditions lead to higher greenhouse gas emissions and surface spreading without irrigation leads to significantly higher ammonia emissions. The study concludes that soil conditions at the time of application are more important than the application technique for fertilization.

Summary: The Guadalete estuary in Spain was found to be a source of CO2, CH4, and N2O to the atmosphere, with CH4 showing the strongest relationship with DOM composition. Terrestrial and microbial humic-like substances with increasing aromaticity were linked to higher pCO2 levels, while N2O was related to the protein-like fraction and humic-like material from anthropogenic activities. This indicates a possible coupling between benthic fluxes of GHGs and DOM in this estuarine system, highlighting the importance of considering DOM composition in studying GHGs distribution in estuaries for better understanding of their roles in response to climate change.

Summary: Urban land-use change affects biogeochemical cycling of carbon and nitrogen and associated greenhouse gas (GHG) emissions. A meta-analysis shows that urbanization increases soil nitrous oxide (N2O) emissions and reduces soil methane (CH4) uptake. These changes are driven by alterations in soil properties, such as bulk density and pH, temperature increase, and management practices, particularly fertilizer use.

Summary: Urban rivers are identified as emission hotspots of greenhouse gases, primarily affected by nutrient supply and hypoxic environments. Meanwhile, temperature-dependent factors influence CO2 emissions in all rivers. Therefore, better recognition of the impact of river networks on global warming is necessary, with management measures needed to more efficiently reduce greenhouse gas emissions.

Summary: This study conducted sampling and analysis of greenhouse gases in the Pearl River Estuary and found that the Pearl River runoff is the main source of greenhouse gases in the estuary. Strong nitrification is an important mechanism for N2O production in the estuary. The development of a hypoxic zone in the estuary significantly increased the concentration of N2O and CH4 in the bottom water and increased the air-water fluxes. This study reveals that greenhouse gas fluxes from estuarine waters to the atmosphere will increase significantly with increasing eutrophication and expansion of hypoxic zones in estuarine waters.

Summary: The dynamics of methane and nitrous oxide in coastal coral reef areas are not well understood. The study in the Great Barrier Reef showed oversaturated CO2 due to calcification and riverine sources, oversaturated CH4 from nearshore biogenic sources and probable offshore aerobic production, and generally undersaturated N2O. The GBR was a slight CO2 and CH4 source and N2O sink during the study, with further research needed to constrain diurnal, seasonal, and spatial dynamics.

Summary: Land use change has a significant impact on soil CO2, CH4, and N2O emissions, with afforested lands showing higher CO2 and N2O emissions compared to abandoned land. The emission of CO2 is positively related to microbial activities, while CH4 uptake is correlated with soil environments and chemical properties. N2O emission is associated with nitrifying genes but negatively correlated with denitrifying genes.

Summary: The study found that diurnal warming and acid rain did not significantly affect CO2 emissions from soil-plant systems during winter wheat and soybean growing seasons, but significantly increased N2O emissions. Additionally, diurnal warming enhanced the positive effect of acid rain on N2O emissions from soil-plant systems in winter wheat farmland.

Summary: This study analyzes data from national and international bodies to assess the status and trends of agricultural nitrogen flows in Bangladesh. Excessive use of nitrogen fertilizer leads to the generation of unutilized reactive nitrogen, which has negative consequences for ecosystem functioning. Achieving a balance between food production and reducing nitrogen input is crucial.

Summary: Conventional tillage (CT) degrades soil and environmental quality, while conservation agriculture, like reduced tillage, can play a significant role in reducing greenhouse gas emissions and maintaining soil organic carbon storage. This study conducted at the Bangladesh Agricultural Research Institute (BARI) evaluated the impact of CT and strip tillage (ST) on greenhouse gas emissions, global warming potential, and net soil organic carbon variations in a rice-mustard-rice cropping system. The findings showed that ST significantly reduced methane emissions, greenhouse gas intensity, and global warming potential compared to CT. Additionally, ST increased net ecosystem CO2 absorption and rice equivalent yields. These results highlight the importance of adopting strip tillage practices in Asian countries to minimize soil carbon loss and reduce greenhouse gas emissions.

Summary: This study examines the factors affecting the adoption of briquette urea (BU) by rice farmers in Bangladesh. The findings reveal that farms specializing in rice production, possessing more assets, using mobile phones for farming, and having better access to extension services are more likely to adopt BU. Empowered women also show a higher propensity for BU adoption. On the other hand, living in the "feed the future zone" decreases the probability of BU adoption.

Summary: This study determined the net carbon emissions and sequestration for maize grown in Bangladesh, and observed spatial and seasonal variations in carbon emissions and sequestration. It is recommended to focus on improving maize grain yields in the wet season and improving fertilizer and water use efficiencies to reduce greenhouse gas emissions. Increasing the area under cultivation with rice-maize or other non-rice crop-based cropping systems can help augment carbon sequestration.

Summary: The response of different soybean varieties to potassium fertilizer varies under different conditions. Basal application of potassium improves pod and seed yield under normal conditions, while top dressing potassium contributes to taller plants and higher grain yield under waterlogged conditions. Additionally, soybean varieties absorb more nitrogen, phosphorus, and potassium under control conditions, resulting in higher seed protein content. However, the response to potassium fertilizer is also influenced by seed germination rate and electrical conductivity.

Summary: With rapid industrialization in Gazipur areas of Bangladesh, untreated industrial effluents have been polluting rice soils which could exert potential ecological risk. Therefore, four different types of industries including chemical, textile and paints, dyeing, and sweater and dyeing were selected to monitor heavy metal pollution in rice soils and assess the ecological risk. Different methods and indices were used to determine heavy metal concentrations and evaluate the pollution level. The findings showed that the soils near the industries were more contaminated, indicating a potential ecological risk.
