Special Issue Information

Dear Colleagues,

In recent decades, the intricate dynamics of transboundary water systems have gained increasing global significance amidst the pressures of human activities and climatic variability. This phenomenon presents significant challenges to socioeconomic and environmental conditions worldwide. Understanding the evolving status and trends within transboundary water systems has thus become paramount on a global scale. This proposed Special Issue aims to shed light on the current state of affairs within transboundary water systems worldwide, with a specific emphasis on studies focused on transboundary water perspectives. By examining key parameters such as aquifer storage changes, groundwater quality, river streamflow alterations, floods/droughts, and lake water storage variations, we seek to unravel the intricate interactions shaping the dynamics of these systems. Leveraging advanced methodologies such as machine learning (ML) and artificial intelligence (AI), hydrological models, nexus modeling, and remote sensing applications, our endeavor is to provide a comprehensive global analysis that underscores the imperative for collaborative management and sustainable strategies. Furthermore, we specifically emphasize the importance of generating data and new tools to enhance our understanding of transboundary water systems. We encourage authors to provide access to their data repositories, fostering transparency and facilitating further research. Additionally, we will establish a data hub where all published papers and generated data will be made available for community use, capacity development, and stakeholder engagement. This resource will assist in making informed, sustainable decisions for food and water security in both local and global regions. Therefore, our Guest Editor team will prioritize high-quality submissions from authors whose primary focus is on advancing transboundary water governance through the development of new datasets, tools, and research innovations. Our ultimate goal is to foster a deeper understanding of transboundary water systems’ vulnerabilities, resilience, and adaptation pathways in the face of evolving global challenges. We invite scientists and researchers to contribute their insights and expertise, exploring topics such as collaborative water management strategies, future scenarios for sustainable water use, and the complex interplay of socio-economic and ecological factors. Together, let us embark on a journey to unravel the complexities of transboundary water systems worldwide, paving the way for informed decision-making and collective action to safeguard the vital water resources essential for global prosperity and well-being.

Climate change is projected to bring substantial changes to hydroclimatic extremes, which will affect natural river regimes and have wide-ranging impacts on human health and ecosystems, particularly in Central Highland Vietnam. This study focuses on understanding and quantifying the projected impacts of climate change on streamflow in the Kon-Ha Thanh River basin, using the Soil and Water Assessment Tool (SWAT) between 2016 and 2099. The study examined projected changes in streamflow across three time periods (2016–2035, 2046–2065, and 2080–2029) under two scenarios, Representative Conversion Pathways (RCPs) 4.5 and 8.5. The model was developed and validated on a daily scale with the model performance, yielding good performance scores, including Coefficient of Determination (R2), Nash-Sutcliffe Efficiency (NSE), and Root Mean Squared Error (RMSE) values of 0.79, 0.77, and 50.96 m3/s, respectively. Our findings are (1) streamflow during the wet season is projected to increase by up to 150%, particularly in December, under RCP 8.5; (2) dry season flows are expected to decrease by over 10%, beginning in May, heightening the risk of water shortages during critical agricultural periods; and (3) shifts in the timing of flood and dry seasons are found toward 2099 that will require adaptive measures for water resource management. These findings provide a scientific foundation for incorporating climate change impacts into regional water management strategies and enhancing the resilience of local communities to future hydroclimatic challenges.

Precise estimation of net radiation (Rn) is fundamental to understanding surface energy balance and is critical for accurately determining crop water requirements, especially using remote sensing and geospatial techniques. The core objective of this study is to evaluate multi-satellite-based net radiations on major cropped areas of the Punjab and Sindh provinces of Pakistan. In this study, overlapping scenes from the Moderate Resolution Imaging Spectroradiometer (MODIS), Landsat 8, and Sentinel 2 were used from 2016 to 2020 along with three temperature products MOD11A1, Landsat 8 (brightness temperature), and ERA5. The multi-satellite-based net radiation estimations on overlapping days were compared with the Global Land Data Assimilation System (GLDAS) dataset. The models based on Landsat 8 and Sentinel 2 data exhibited good performance, with a Nash–Sutcliffe Efficiency (NSE) of 68.9%, a mean error (ME) of 13.918 W/m2, and a bias of 50.669 W/m2. The results indicated that Landsat 8 and Sentinel 2 data produced reliable estimations of net radiation, while MODIS data tended to overestimate due to its higher spatial resolution and broader coverage area. Landsat 8-based estimations are good compared to others, as it has good correlation coefficient and lower RMSE values. The study concludes that Landsat 8 provides the most reliable estimates of net radiation for determining crop water requirements, outperforming other datasets in accuracy. The findings underscore the importance of using high-resolution multi-satellite data for precise agricultural water management, recommending its use in future studies and water resource planning in Pakistan.
