This dissertation consists of three self-contained, yet closely related, papers summarizing the results of a comprehensive study aimed at the development of a decision support system for sustainable water resources management for the Zhangye Basin in northwestern China. The first paper presents a 3D groundwater flow model to represent groundwater dynamics of the basin from 1999 through 2010 using MODFLOW-2005. The regional 3D groundwater model provides reliable information of the flow field and produces detailed water budgets for management purposes. It defines the intensive groundwater-surface water interaction zones, and reveals the increasing flux exchange due to both climate change and human activities. The second paper presents an integrated 3D groundwater-surface water flow model using GSFLOW. The model calibration was done by first running PRMS and MODFLOW-2005 models separately, and then followed by the calibration of the integrated GSFLOW model. The model shows a detailed trend of water storage changes and their relationship with each inflow and outflow item. More importantly, this study demonstrates the applicability of integrated basin-scale models in characterizing the groundwater-surface water(GWSW) interaction, reproducing the flow system, and supporting sustainable water resources management while accounting for the effects of climate change in arid inland river basins. The third paper presents an efficient decision support tool, taking into consideration the relevant complexities and interactions in different water resource components, to inform decision making for water resources management for the Zhangye basin. On the basis of data collection and data mining, incorporated with integrated hydrological conceptual models and numerical models, a Bayesian network (BN) has been developed and calibrated by K-fold cross validation. The trained BN model captures the important hydrological cycle characteristics and uncertainty of related factors to provide the optimal management solutions under consideration. While this study is based on the Zhangye basin, the concepts and approaches developed in this study are of general applicability. The integrated GWSW modeling, coupled with a BN construct, provides an innovative tool to inform decision making in water resources management.

This book presents essential case studies on the integrated modelling of ecosystem services and land-use change in the field of landscape ecology. The case studies were mainly conducted in the Zhangye oasis of the Hexi corridor and the upper reaches of the Heihe river basin, including Loess plateau (for wind power) and the inland waterways of the Yangtze River (for the regulation of extreme events). The book puts forward an integrated modelling method, including human activities, natural processes, land-use change, and ecosystem management, and explores multiple scenarios based on the interests of local managers and their implications for ecosystem services. As the book demonstrates, the integrated modelling method for ecosystem services and land-use change can serve as a valuable tool for gauging the impact of various development scenarios in this study area, and in other regions with similar characteristics. In addition, numerous charts and diagrams are included in each chapter, facilitating the simulation and assessment of specific land-use change impacts on ecosystem services in various study areas.

This open access volume is the first comprehensive assessment of the Hindu Kush Himalaya (HKH) region. It comprises important scientific research on the social, economic, and environmental pillars of sustainable mountain development and will serve as a basis for evidence-based decision-making to safeguard the environment and advance people’s well-being. The compiled content is based on the collective knowledge of over 300 leading researchers, experts and policymakers, brought together by the Hindu Kush Himalayan Monitoring and Assessment Programme (HIMAP) under the coordination of the International Centre for Integrated Mountain Development (ICIMOD). This assessment was conducted between 2013 and 2017 as the first of a series of monitoring and assessment reports, under the guidance of the HIMAP Steering Committee: Eklabya Sharma (ICIMOD), Atiq Raman (Bangladesh), Yuba Raj Khatiwada (Nepal), Linxiu Zhang (China), Surendra Pratap Singh (India), Tandong Yao (China) and David Molden (ICIMOD and Chair of the HIMAP SC). This First HKH Assessment Report consists of 16 chapters, which comprehensively assess the current state of knowledge of the HKH region, increase the understanding of various drivers of change and their impacts, address critical data gaps and develop a set of evidence-based and actionable policy solutions and recommendations. These are linked to nine mountain priorities for the mountains and people of the HKH consistent with the Sustainable Development Goals. This book is a must-read for policy makers, academics and students interested in this important region and an essentially important resource for contributors to global assessments such as the IPCC reports.

This book of Springer Proceedings in Geoarchaeology and Archaeological Mineralogy contains selected papers presented at the 7th Geoarchaeology Conference, which took place during October 19–23, 2020, at the South Urals Federal Research Center, Ural Branch of Russian Academy of Sciences, Miass, Russia. The Proceedings combine studies in archeometry, geoarchaeology, and ancient North Eurasian technologies, including paleometallurgy, stone tools investigation, past exploitation of geological resources, bioarchaeology, residue analysis, pottery, and lithics studies. This book also specializes in various non-organic materials, rocks, minerals, ores, and metals, especially copper and metallurgical slags. Many types of research also use modern analytical methods of isotopic, chemical, and mineralogical analysis to address the composition and structure of ancient materials and the technological practices of past human populations of modern Russia, Ukraine, Turkmenistan, Tajikistan, and Mongolia. This book is intended for archaeologists, historians, museum workers, and geologists, as well as students, researchers from other disciplines, and the general public interested in the interdisciplinary research in the field of archaeology and archaeological materials, strategies and techniques of past quarrying, mining, metallurgy and lithic technologies at different chronological periods in Eurasian steppe and adjacent forest zone.

In order to face the challenge of disappointing returns on public investment in irrigation and drainage new solutions have emerged. These solutions are based on widely available technology and new management and governance options. The main message of "Reengaging in Agricultural Water Management" is that the irrigation and drainage sector should not continue to be dealt with as a stand-alone sector, but should be integrated into a broader perspective, one that embraces the objectives of productivity growth, poverty reduction, natural resources management and environmental protection.

This study presents a multi-disciplinary approach for investigating the interactions between groundwater and surface water in the semi-arid Hailiutu catchment in the Erdos Plateau, Northwest China. The study consists of statistical detection of river flow regime shifts at the basin level; multiple in-situ measurements for quantifying groundwater discharges using hydraulic, hydrochemical and temperature methods at a local scale; analysis and simulation of impacts of different land use scenarios on groundwater and surface water interactions at the sub-catchment scale; and the quantification of temporal and spatial groundwater and surface water interactions with hydrochemical tracers and modelling methods at the basin scale. The study found that the river flow consists of mainly groundwater discharges at all scales. The river flow regime has been intensively altered by human activities, such as the construction of reservoirs, water diversion, groundwater exploitation, and reforestation. Water use by plants and crops consumes majority of the precipitation. Groundwater sustains vegetation growth and feeds river discharges. The water resources and ecosystem management priority should reduce evaporative water uses by promoting dry resistant plant species for vegetating sand dunes and lower irrigation demand crops for socio-economic development. Furthermore, the Hailiutu River catchment must manage the groundwater recharge for water resource conservation and the maintenance of healthy ecosystems.
