Summary: This paper presents the first regional-scale investigation in the Piedmont Po plain on the relationship between groundwater temperature (GWT) and climate variability. The study found that GWT is more resilient to climate change than air temperature (AT), with some areas showing behavior that deviated from the standard trend. The importance of accurate measurement location for GWT instruments was also emphasized.

Summary: The study on ecosystems in the arid/humid transition zone of northern China found that vegetation activity is influenced by both climatic and non-climatic factors, with growing season temperature and growing season aridity index being the main driving factors.

Summary: Climate change is causing an increase in water demand and worsening aridity in terrestrial ecosystems. This study examined the spatiotemporal variability of the global aridity index from 1970 to 2018. The results showed an overall drying trend, with humid and semi-humid regions experiencing the most significant drying. The Qinghai-Tibet Plateau has become wetter due to increased precipitation. The study also found that decreasing precipitation and increasing potential evapotranspiration are the main drivers of global drying.

Summary: This study analyzes almost 1 million river junctions and over 4.2 million groundwater wells in the contiguous United States and reveals that the branching angles of stream networks vary systematically with the degree to which streams lose or gain water from nearby groundwater aquifers. This relationship persists across different stream orders and channel gradients, providing the first continental-scale observational evidence of the potential contribution of groundwater to the development of large-scale drainage patterns.

Summary: This study investigates potential future changes in climate zones using root-layer soil moisture as an indicator. The research shows that global drylands may expand by 10.5% by the end of the 21st century, with higher growth in semiarid and subhumid regions and reductions in arid and humid zones. Evaluating climate zone changes with soil moisture provides more accurate results, especially with higher expansion rates in mid-high latitude regions.

Summary: In recent years, greenhouse gas emissions have led to extensive climate changes and increased occurrence of extreme events, such as droughts. This study examines precipitation and temperature variations and past/future drought characteristics in Iran using data from synoptic stations and general circulation models. Results show that precipitation will generally decrease in future periods across Iran while temperature will decrease in southern/southeastern regions and increase in northwestern/northern areas. Drought severity, peaks, and duration will be highest in semi-arid and arid regions, with the longest drought duration projected in the southeast and west of Iran. Overall, future droughts are expected to be more severe, longer, and have higher variability compared to the baseline period.

Summary: This study investigates the evolution of temperatures at various locations in Pakistan from 1950 to 2013, revealing that temperature changes are more significant in urban and town areas compared to rural areas. The increase in minimum temperatures is more pronounced than that in maximum temperatures, with a lesser change in summer temperatures compared to other seasons throughout the entire period.

Summary: Coastal ocean acidification is a global problem due to climate change, and the study reveals a close relationship between submarine groundwater discharge (SGD) and coastal ocean acidification in Hong Kong's coastal waters. The direct influence of SGD on seawater pH decline is evaluated for the first time, and the results show that SGD contributes significantly to seawater pH variation through direct input of carbonate species. In addition, SGD also affects seawater pH through nutrient loadings. Understanding and managing groundwater is crucial in mitigating coastal ocean acidification.

Summary: The Aridity Index (AI) calculated from meteorological stations in Xinjiang from 1961 to 2020 shows that the climate in Xinjiang, especially southern Xinjiang, has become wetter over the past 60 years. The total area of arid regions has decreased while semi-arid, humid, and semi-humid areas have increased, particularly since the early 2000s. The climate reversal occurred in the 1990s and an abrupt change in AI was observed in 1986, leading to a continuous wetting trend in the study region. The climate changes in Xinjiang mainly exhibit oscillation periods of 2.5 years and 6 years, with the 6-year period being more significant.

Summary: Groundwater is a valuable global resource, and its recharge rates vary greatly across the world. This study finds that global recharge is closely related to aridity levels. Higher recharge rates than previous estimates are likely due to preferential groundwater recharge and discharge occurring at finer scales than global models. The higher recharge estimates suggest that more groundwater contributes to evapotranspiration and streamflow than previously thought.

Summary: This study aims to unravel the effects of climate change on wheat yield in Iran and provide valuable insights to researchers, policymakers, and farmers. The findings show that climate factors can have both positive and negative effects on wheat yield, with differences across regions. The adaptation of irrigated and rain-fed wheat varieties to climate change also varies.

Summary: Climate variability and insufficient irrigation pose significant challenges to agricultural productivity and food security in Nepal. Although integrating surface and groundwater use has been proposed as a strategy for enhancing efficiency and adapting to climate change, there is a lack of technical expertise in conjunctive management. This article presents a comprehensive framework for assessing conjunctive management from a systems-level perspective and suggests strategies for its implementation in Nepal, using a case study in Western Nepal as an example.

Summary: This study examines the impact of climate change on groundwater resources in Iran and finds that there is a lack of research in this area, especially in developing countries. Climate change is expected to have negative effects on groundwater resources, including declining water levels and reduced storage. Without changes in current management approaches, the water crisis in Iran will worsen.

Summary: The changes in agroclimatic resources have caused serious economic damages in many regions worldwide. The Balkan Peninsula, including Bulgaria, has been greatly affected by rising temperatures, changes in precipitation distribution, and increased frequency of extreme events such as droughts and frosts. This research aims to assess the changes in agrometeorological conditions for grain crop growth and identify suitable agro-technologies for adaptation. The study also takes into account the characteristics of contemporary varieties and hybrids of spring and autumn cereals.

Summary: Rainfall-runoff relationship in arid regions is unique and challenging to study. This study aims to develop a method for estimating unit hydrograph at finer time resolutions, especially in ungauged areas, by using observed wadi-flow and tipping bucket rainfall measurements. The proposed methodology can be used for water resources management in similar climate and geographical settings.

Summary: This study proposes a method for evaluating the risks of slope failure induced by heavy rain. The method combines infiltration analysis, surface flow analysis, and slope stability analysis using a three-dimensional limit equilibrium method. It is found that this method can roughly represent actual slope failure and the use of high-resolution terrain data obtained from UAVs is important in evaluating micro-topography stability.
