Summary: The overuse of seed and chemical inputs is a major obstacle to sustainable rice production in Vietnam. This study compared different crop establishment practices and found that mechanized transplanting can reduce seed and pesticide usage while maintaining similar levels of net energy balance, net income, and greenhouse gas emissions as other non-mechanized planting practices.

Summary: This study assessed the contribution of three different rice cultivation practices (conventional, system of rice intensification, and zero-tillage) to carbon emissions. Results showed that fertilizer application significantly influenced greenhouse gas emissions, and all three cultivation strategies acted as carbon sinks, with the system of rice intensification yielding the highest carbon sequestration values. The ratio between ecosystem services and disservices was highest for the system of rice intensification, followed by zero-tillage and conventional cultivation.

Summary: The study revealed that soil organic carbon (SOC) content in the Guanzhong Plain decreased significantly with soil depth in the upper 100 cm layer, while it remained relatively low and stable in deeper soil layers. Unlike in the upper layers, SOC in deep soils was primarily influenced by soil properties. Changes in agricultural land use did not significantly impact SOC in both shallow and deep soils of the study area.

Summary: Prolonged paddy management alters the Fe isotope composition of soil and rice plants, indicating the origin of rice plants and the extent of past soil paddy management. The study found that prolonged paddy management reduces Fe concentrations in the topsoil, leading to an enrichment of heavy Fe isotopes. The Fe content in rice also increases with paddy age, while its Fe isotope composition resembles that of the Fe plaques on the roots rather than paddy soil.

Summary: This article discusses the application of Life Cycle Assessment (LCA) in rice production. Through the study of 76 papers, it is found that most studies have evaluated the environmental impact of rice production and identified opportunities for improvement. However, there are discrepancies in the factors considered and the methodology used, making it challenging to compare LCA results.

Summary: This study used bi-temporal airborne lidar data to compare changes in vegetation height near anthropogenic disturbances in the Oil Sands Region of Alberta, Canada. The results showed that up to 50% of wetlands were disturbed by anthropogenic activities, with bogs experiencing increased shrub growth and expansion, while fens and swamps showed varying responses to disturbances. Wetland shapes becoming elongated were associated with a decline in shrub prevalence between the two time periods.

Summary: This study examines the technical efficiency in farming by considering nitrogen pollutants and explicitly modeling them as undesirable outputs. The research finds improvements in green technical efficiency but no change in conventional technical efficiency in rice-producing provinces in the Philippines. The quality of seeds is identified as an important factor for green technical efficiency but not for conventional technical efficiency.

Summary: Jumla is a Himalayan region in Nepal with abundant natural resources and biodiversity. Jumli Marshi, a local rice variety, is facing a decline in cultivation due to low productivity and susceptibility to diseases. To preserve local diversity and contribute to sustainable food production, the conservation and cultivation of Jumli Marshi should be promoted.

Summary: The study found that in alkaline soil, the DSR and SRI cultivation practices can improve water productivity of rice compared to the traditional PTR cultivation technique, but their yield is slightly lower. Additionally, the DSR cultivation method has a more favorable impact on the subsequent lentil growth, and the nutrient status of nitrogen and phosphorus in the soil is crucial for sustaining rice yield.

Summary: The rapid degradation, overexploitation, and encroachment of floodplain wetlands have led to a decline in fish diversity and production. This study implemented pen culture of grass carp as a biocontrol for macrophytes in a shrinking floodplain wetland. The results showed that the pen culture was economically viable and increased fish production. Grass carp played a significant role in macrophyte management and enhanced fish biomass.

Summary: Constructed wetland is an efficient eco-technological conglomerate that combines water security, energy possibility, and environmental protection. It is important to further explore the roles of individual wetland components, focusing on the effects of plants and biofilms, as well as the impact of alternative low-cost substrate materials on target pollutants.

Summary: This study investigates the impact of rice expansion on traditional wetland management. The findings indicate that the increase in rice price encouraged farmers to shift from conventional crops. However, the expansion of rice production has led to the reduction of wetland areas and the compromise of ecosystem services. It is important to communicate the sense of ownership and benefits of wetland resources to reduce abusive utilization.

Summary: Ratoon rice (RR) is more efficient and sustainable than single-season rice (SR) and double-season rice (DR), with enormous potential to expand its cultivation area in China for increasing rice production. The suitable cultivation region and paddy area for RR were estimated using the Maxent model, showing significant differences in potential areas compared to DR, indicating opportunities for growth in RR cultivation without reducing current DR planting area.

Summary: This study examined the suitability of biochar mixed with wheat straw returning in rice-wheat rotation regions and its effects on water quality, nitrogen and phosphorus leaching losses, and rice yield. The results showed that total straw returning negatively impacted water quality and leaching losses, but biochar application mitigated these effects.

Summary: This study investigated the differences in waterbird-mediated endozoochory among five South American waterfowl species and the impact of seasonality on dispersal functions. The results revealed that these waterfowl dispersed 2,066 intact diaspores from 40 different plant taxa, with at least one diaspore present in 65% of fecal samples, predominantly from native amphibious and emergent plants. Seasonal variation was evident, with more diaspores found in the cold period compared to the warm period, and a strong interaction between bird species and season was the most important predictor of variation in both taxonomic richness and abundance of diaspores.

Summary: In subtropical seasonal ponds, the alpha diversity of zooplankton hatchling communities is primarily related to substrate heterogeneity, and the beta diversity of the total community is influenced by annual rainfall and substrate heterogeneity. The beta diversity of Cladocera is solely affected by annual rainfall, while substrate heterogeneity influences the overall beta diversity of Rotifera. Overall, the distinct relationships of the zooplankton groups with the explanatory datasets suggest differing sensitivities to impacts in habitat structure and climatic conditions in subtropical seasonal ponds.

Summary: Wetlands, one of the most diverse environments, are threatened by human activities. This study examines the relationship between dormant zooplankton stages and clay removal, as well as the influence of adding topsoil from natural wetlands to mined wetlands. The results suggest that sediment donation from natural to mined wetlands may help establish a more diverse community in disturbed systems.

Summary: The study found that family-level resolution can be used as a surrogate of finer taxonomic resolutions to describe invertebrate community structure patterns in New World freshwater wetlands without significant information loss. However, conclusions on biodiversity patterns derived from datasets with different numerical resolutions should be critically considered.

Summary: The metacommunity organisation of aquatic insects in temporary ponds in southern Brazil is influenced by environmental factors (habitat structure; water chemistry; climate) and spatial factors, with differences observed between strong-flying and weak-flying insect subsets. Climate and fine-scale spatial factors play a significant role in structuring the composition of strong-flying insects, while weak-flying insects are more affected by local water chemistry and spatially structured climate.
