Summary: This study focuses on determining trends in precipitation and streamflow series in the Upper Blue Nile River Basin in Ethiopia. The Discrete Wavelet Transform (DWT) and Mann-Kendall test were used to analyze the data. The results show an increasing but insignificant trend in precipitation stations, while streamflow stations exhibit a significant increasing trend. The combined use of DWT and Mann-Kendall test reveals that periodic events up to 4 years have a greater influence on the observed trends.

Summary: This study proposes a strategy of adding an outer loop to modify the over-whitening (OW) operation for trend test in hydrologic and climate time series. Two simulation experiments and analysis of six real cases are conducted to evaluate the performances of different methods and analyze the influence of significance level on the trend test. Results show that the previous OW operation still has the risk of misjudging trends, and the proposed strategy is necessary and effective. The two methods have similar accuracy in trend test results, but may produce opposite results when determining whether a significant trend is a pseudo trend or not.

Summary: This study explores the use of a vegetation cover index as a pollution warning tool in gold mining areas in Northwest Iran. The study analyzed Landsat images to extract normalized difference vegetation index (NDVI) maps and calculate vegetation cover in different zones. The study also investigated trends in vegetation cover and assessed the correlation with climate parameters. Results show that vegetation cover has been significantly reduced in the mining activities areas, but an overall upward trend is observed in the downstream area with no chemical leakage. The study demonstrates the potential of using NDVI and statistical methods to quantify the effects of human activities on surface biophysical characteristics.

Summary: This study investigates the trends of rainfall and temperature in agricultural regions of Turkey from 1969 to 2020. The findings suggest that there is no significant trend in monthly rainfall according to the Mann-Kendall test, but both innovative approaches show a decreasing (increasing) trend in November (September) for most stations. As for temperature, there is a general increasing trend or no trend throughout the year, except for April. The results also reveal that the seasonal variability of rainfall is complex and persistent in all agricultural regions. The irregular changes in rainfall and rising temperatures have negatively affected crop yield and may require more irrigation.

Summary: Overfertilization is common in rainfed apple orchards on China's Loess Plateau, but its impacts on soil physicochemical properties in deep soil profiles are poorly understood. This study found that different land-use types showed divergent distribution patterns in soil properties, with low variability for SWC and pH, moderate variability for NH4+-N, AP, and AK, and high variability for SOC, NO3--N, and EC. The results also showed that fertilization influenced soil water content, NO3--N, AP, and AK, and NO3--N played a crucial role in regulating pH and EC. Soil profiles were useful for studying the evolution of soil quality.

Summary: The Mediterranean region is expected to experience more intense rainfall events and severe droughts due to climate change, leading to an increase in runoff and erosion rates in agrosystems. Vegetation cover can help reduce erosion and the soil seed bank can provide cost-effective vegetation. This study assessed the effect of vegetation cover on seed loss in vineyards and evaluated the differences in the soil seed bank along a transect. The results suggest that vegetation may not protect interrows from runoff-induced seed loss.

Summary: This research introduces a hybrid four-sub-deep neural network (HFSD) model for partitioning NEE into GPP and ER. The HFSD employs dual sub-deep neural networks to estimate ERa and ERb and incorporates GPP and environmental variables to predict vegetation transpiration. The results of the model show that the dual sub-DNNs architecture enhances the accuracy of ER simulations, while using EC-derived T as a constraint improves the accuracy of GPP simulations. Correlation analyses suggest that solar radiation and air temperature primarily influence the seasonal variations in GPP and ER, while soil moisture has a strong impact during dry seasons. This study advances the biophysical description of data-driven models for NEE partitioning and enhances the accuracy of GPP and ER estimates.

Summary: This study investigated changes in vascular plant species in Central European arable fields and their edges from 1930 to 2019. The results showed a small decline in overall species occupancy, but a more pronounced species turnover. Species with environmental preferences for nutrient-rich sites with neutral pH increased in occupancy, while species typical for arable fields decreased. No response to climate change was observed, and there was a decrease in archaeophytes and native species and an increase in neophytes.

Summary: Proper bed substrate selection is crucial for the performance of constructed wetlands, especially when treating drainage water with high nitrogen and low carbon and phosphorus concentrations. In a field-scale pilot plant, adding a carbon-rich substrate such as soil or biochar increased phosphorus availability in beds. Beds with soil displayed higher microbial density and activity, as well as better plant growth compared to gravel. These findings highlight the importance of selecting suitable substrates for treating irrigated agricultural water.

Summary: Considerable advances have been made in the assessment and mapping of soil organic carbon stocks. However, the rates of change in carbon stocks are influenced by various factors and need to be quantified. This study found that sandy soils under cultivation and forests have different organic carbon stocks. Factors such as tillage, irrigation, and nitrogen applications contribute to the decline in soil organic carbon stocks. Afforestation of abandoned cultivated fields can increase soil organic carbon, but it is still lower than soils under forest that have never been cultivated.

Summary: Grazing exclusion is a widely implemented strategy for restoring degraded grassland ecosystems and increasing carbon stocks. This study analyzed data from 199 experiments to understand the temporal responses and factors influencing plant and soil carbon stocks following grazing exclusion in different grassland ecosystems. The results showed that plant biomass carbon stocks and soil organic carbon stocks decreased exponentially or rationally with years since enclosure. Grazing exclusion had positive effects on aboveground biomass carbon, but the effects on belowground biomass and soil carbon were influenced by climate, initial carbon levels, and grazing exclusion duration. The response of carbon stocks to grazing exclusion stabilized after approximately 40 years, with soil carbon sequestration showing a lagged pattern compared to plant biomass carbon. The study highlighted the effectiveness of grazing exclusion in regions with low carbon content and non-water limited conditions. However, it might not be an effective measure to increase soil organic carbon stocks in water-limited areas like desert grasslands.
