Summary: It is widely accepted in geospatial analysis that automated calculation of thalweg networks from a digital elevation model produces a theoretical flow system which differs significantly from natural river networks. While efforts have been made to optimize numeric calculations, none has suggested using this difference as specific data for the study context. The IDPR concept aims to measure the disparity between the theoretical drainage system and branching rivers to determine spatial infiltration and runoff distribution.

Summary: Permanent soil flooding resulted in higher grain yield and malondialdehyde (MDA) concentrations in leaves in plants from the resistant genotype IRGA 425 compared to the sensitive genotype BR-IRGA 409. In contrast, two cycles of alternate soil drying resulted in equivalent grain yield and MDA concentrations in both genotypes. Resistance to iron toxicity in IRGA 425 plants seems related to limited Fe translocation to shoots, increased tolerance to oxidative stress in leaves, and higher expression of Ferritin, OsGAP1, OsWRKY80, and Oryzain-alpha genes. Plants from the BR-IRGA 409 cultivar (sensitive to Fe toxicity) improved growth and yield under the interrupted irrigation treatments, probably due to lower Fe availability in the soil solution. Management of water irrigation successfully alleviated Fe toxicity in rice plants cultivated in field conditions.

Summary: Improved irrigation management, such as furrow-irrigated rice (FR), shows potential to reduce methane emissions but may increase nitrous oxide emissions. While FR and FRCC significantly reduced CH4 emissions, they also increased N2O emissions compared to MIRI. Nonetheless, there was no significant difference in the overall global warming potential among FR, FRCC, and MIRI.

Summary: Urbanization negatively affects water quality in streams by reducing stream-groundwater interactions, impacting the stream's ability to naturally attenuate nitrate. The study found that heavily urbanized and hydrologically-disconnected reach was a net source of nitrate, while the downstream connected reach served as both a source and sink depending on the season. Groundwater connection in the downstream reach reduces annual nitrate loads and provides more opportunities for nitrate sources and sinks year-round.

Summary: The study showed that precipitation events in rocky terrains lead to deep water infiltration and groundwater recharge, while infiltration in deep soils in areas such as valleys and high plains is very limited and influenced by intense evaporation, resulting in reduced groundwater recharge. High rain intensity was found to be the most dominant factor responsible for deep water infiltration, highlighting the strong coupling between geomorphological features and groundwater recharge.

Summary: This study assesses the impact of irrigation on groundwater recharge in the northwest Rajshahi district of Bangladesh. The results show an increase in groundwater use for irrigation, but a persistent decrease in groundwater levels. About 33% of total irrigation becomes return flow and contributes to groundwater recharge, with irrigation return flow accounting for 98% of total recharge in the dry season. Proper measurement and management of irrigation water are crucial for sustainable groundwater resource management in this region.

Summary: The hydrology of alpine and subalpine areas in the Colorado Front Range is changing due to warming and alterations in precipitation patterns. The study found that soil hydraulic conductivity is comparable to shallow aquifer hydraulic conductivity. Higher hydraulic conductivity was observed in alpine areas underlain by periglacial deposits and lower conductivity in till-covered subalpine areas. As temperatures rise and snowmelt occurs earlier, alpine soils may become more vulnerable to drought, impacting the connectivity between snowmelt streams and downstream areas.

Summary: Increasing selection differential and decreasing cycle time can accelerate the rate of genetic improvement. Creating and capturing higher genetic with higher accuracy within the shortest possible time is crucial for enhancing genetic gain. Comprehensive yield testing at multi-locations at early generations together with shorter line fixation time can expedite the rapid recycling of parents in the breeding program through recurrent selection. Genomic selection is efficient in capturing high breeding value individuals, considering additive genetic effects of all genes, and reducing breeding cycle time, thereby enhancing genetic gain.

Summary: This study investigated the accumulation of PFAS in rice and found that PFAS exists in atmospheric particles, rainwater, irrigated water, soil, and rice plants. PFAS primarily enter the paddy field through atmospheric particles, and rainfall is a significant source of irrigation water contamination. Although there were no major differences in the residual PFAS trends in different rice varieties, the distribution of PFAS in soil, air, and rainwater varied. These findings are important for the daily exposure assessment of PFAS in rice consumption by different populations.

Summary: Good index selection is crucial in minimizing basis risk in weather index insurance design, especially in the face of hydroclimatic variabilities. This study found that minimum temperature during crop flowering to maturity phase and average streamflow during crop maturity phase were key factors influencing rice yields in different seasons in Malaysia's irrigated double planting system. Based on these findings, temperature- and water-supply-based indices are recommended as foundations for developing insurance contracts for the rice system in northern Peninsular Malaysia.

Summary: Arctic warming has led to increased vegetation growth and soil respiration, with the most severe impacts during the cold season. An improved Earth system model is able to better capture the CO2 emissions over Arctic tundra. The rate of warm-season net CO2 uptake is increasing faster than that of cold-season emissions, potentially turning the Alaskan Arctic tundra into a net CO2 sink by 2100.

Summary: The presence or absence of rice plants was found to have different effects on the concentration of MeHg in rice paddy soil, with methylation being the dominant control in non-vegetated soil and demethylation being the dominant control in vegetated soil. The presence of rice plants reduced MeHg production capacity and resulted in lower variance of MeHg concentrations in the soil.

Summary: This study examined variations in the organic matter functional groups of peat samples collected from different latitudes and elevations using Fourier Transform Infrared Spectroscopy. The results showed that peat from high latitudes had higher carbohydrate content, while peat from low latitudes had higher aromatic content. For peat from similar latitudes but different elevations, higher elevations had higher carbohydrate content and lower aromatic content. These findings are important for understanding the response of peatland soil to climate change.

Summary: When organic peat soils in Southeast Asian peatlands become dry, they become flammable and can lead to catastrophic fire events. This study used neural networks to model soil moisture and found that future climate change, including reduced precipitation and increased evaporative demand, will decrease soil moisture. This may accelerate peat carbon emissions and suggest that degraded areas with less tree cover are more vulnerable to climate change, highlighting the need for urgent peatland restoration.

Summary: Tropical peatlands hold significant carbon stocks in the form of peat, with peat domes being the main carbon storage structure. Measuring the subtle topographic relief of these peat domes is challenging, but spaceborne laser altimetry data from satellites like GEDI and ATLAS could provide valuable insights. The study evaluated the accuracy of these data in comparison to airborne lidar data, and found that with spatial filtering, the spaceborne platforms can provide useful altimetry data for tropical peatlands.

Summary: In this study, we investigated the source of groundwater recharge in the Bengal Basin using stable water isotope measurements. Through Monte Carlo statistical analysis, we found distributions of possible recharge sources by considering the variability of isotope ratios. Our results show that there has been a shift in groundwater recharge sources in recent decades, with an increase in recharge from stagnant surface water bodies and a decrease in direct infiltration of precipitation. This shift is attributed to an increase in standing water in irrigated rice fields and ponds, as well as an increase in the downward hydraulic gradient during the dry season driven by pumping.
