Water-soil-vegetation dynamic nexuses affect, and are affected by, both human activity and climate change. Inappropriate land management practices can result in soil and vegetation degradation, which in turn will likely alter natural hydrologic processes, leading to more frequent and severe flooding and drought. In response, an altered hydrologic condition tends to prompt soil erosion by wind and water, which can cause further vegetation degradation or even loss. Such nexuses will likely become more interwoven in changing climate because the non-stationary climate can further deteriorate the already-altered hydrologic condition. So far, our understanding is incomplete regarding how such nexuses maintain or break equilibriums between water, soil, and/or vegetation in terms of eco-environmental resilience. This book: 1) conceptualises the interrelated physical processes of water-soil-vegetation systems; 2) introduces mathematical models for simulating the processes; and 3) develops a variety of modelling cases of selected systems across the world.

Water-soil-vegetation dynamic nexuses affect, and are affected by, both human activity and climate change. For a given area, inappropriate land management practices can result in soil and vegetation degradation, which in turn will likely alter natural hydrologic processes, leading to more frequent and severe flooding and drought. In response, an altered hydrologic condition tends to prompt soil erosion by wind and water, which can cause further vegetation degradation or even loss. Such nexuses will likely become more interwoven in changing climate because the non-stationary climate can further deteriorate the already-altered hydrologic condition. So far, our understanding is incomplete regarding how such nexuses maintain or break equilibriums between water, soil, and/or vegetation in terms of eco-environmental resilience. This book: 1) conceptualises the interrelated physical processes of water-soil-vegetation systems; 2) introduces mathematical models for simulating the processes; and 3) develops a variety of modelling cases of selected systems across the world. Currently, there are no books focusing on this topic though some incomplete information has been scattered in various peer-reviewed journals and project reports. This book provides a systematic elucidation of this important topic and serves as a one-stop information source. Upon reading this book, the reader can apply the materials to conduct advanced research on this topic and develop practical measures in protecting fragile vegetation ecosystems and confronting climate change. The broader application is to prevent land degradation and desertification as induced by climate change and human activities (e.g., development and grazing). Recommended for researchers and graduate students. Key Features: Includes both fundamental principles and practical applications Emphasizes semiarid water-soil-vegetation nexuses rather than individual processes Deciphers dynamics and interrelations of the physical processes of semiarid water-soil-vegetation systems Addresses impacts of climate change from practical management perspectives Maximizes readability by including illustrations, pictures, and annotated equations.

Water-Soil-Vegetation Nexus and Climate Change presents a broad overview of the research needs and approaches regarding water-soil-vegetation nexus and climate change. It includes chapters discussing water budget and factors that affect hydrologic processes such as precipitation, runoff, infiltration, evapotranspiration, soil water, and groundwater, in addition to a focus on consumptive (e.g., domestic and irrigation) and non-consumptive (e.g., eco-environmental) water uses, and water shortage. Throughout Water-Soil-Vegetation Nexus and Climate Change chapters specifically deal with the fundamental principles and also case studies, applications, and decision support tools, that can be usable for developing practical management measures in sustaining our eco-environment and society by maintaining an optimal water-soil-vegetation equilibrium. Written with water resources students and professors in mind, this book will provide the reader with further knowledge on the water-soil-vegetation nexus and its connection to climate change. - Includes both principles and applications, providing the reader with options for both application types as needed - Emphasizes the nexuses rather than individual processes, allowing the reader to understand the whole picture - Presents case studies and decision support tools that can be used for developing practical management measures in changing climate

This book presents a state-of-the-art scientific overview of the influence of terrestrial vegetation and soils within the Earth system. It deals especially with interactions between the terrestrial biosphere and the atmosphere via the hydrological cycle and their interlinkage with anthropogenic activities. Measurements gathered in integrated field experiments in the Sahel, the Amazon, North America and South-east Asia confirm the importance of these interactions, but a substantial data consolidation effort still needs to be undertaken. Observations are complemented by modelling studies, including regional models that simulate flows and transport in river catchments, coupled land-cover and regional climate systems, and Earth-system and global circulation models. Water, nutrient and sediment fluxes in river basins are also discussed and are shown to be highly impacted and regulated by humans through land use, pollution and river engineering. Finally, the book discusses environmental vulnerability and methodologies for assessing the risks associated with regional and global climatic and environmental variability and change.The editors emphasise that the results reported in this book are based on the research work of many individual scientists and teams around the world associated with the objectives of the IGBP-BAHC and WCRP-GEWEX international research programmes.

Current climate change trends are affecting the magnitude and recurrence of extreme weather events. In particular, several semi-arid regions around the planet are confronting more intense and prolonged lack of precipitation, slowly transforming these regions into deserts. In this thesis we present a stochastic (meso-scale) model for vegetation-precipitation interactions for semi-arid landscapes. Extensive simulations with the model suggest that persistence in current trends of precipitation decline in semi-arid landscapes may expedite desertification processes by up to several decades.

Located in a narrow grassland corridor between the semi-desert and a mountain range in Northwest China, the research area Urumqi Region is despite its semi-arid climate in a relatively favourable hydrological situation. The nearby mountains provide water for settlements and agriculture, making human development possible in the first place. Due to the development of agriculture, population and economy during the last sixty years and the increasing water consumption, a demand- and population-driven water scarcity exists today and is expected to aggravate. At the same time, the effects of climate change and land use transformations on the hydrological system and the water availability are uncertain. This study evaluates the recent and future situation by combining a hydrological water balance model for the simulation of the water supply based on scenarios of climate and land use change with a socio-economic model for projecting the future water demand including predicted growth of population and economy.

Hydrology in semi-arid areas is highly impacted by changes in land cover and climate, and research and management are dependent on tools to assess change. Research will be presented that describes methods for mapping and modeling land cover and climate changes and their effects on hydrological systems. Land cover mapping using fast Fourier transforms showed high accuracy compared to traditional techniques. Exploitation of land for natural gas infrastructure is an important form of land use change in the Big Piney-La Barge Oil and Gas Field development area. We used a calibrated SWAT model to simulate hydrology before and after development in this research. Methods for modeling spatially explicit future land management scenarios were built into a GIS system and used in hydrologic models to forecast potential changes to the hydrologic cycle. The KINEROS2 hydrological model was used to simulate hydrology in this study to show the impacts of different management practices. The WRF climate model was used in conjunction with the calibrated SWAT model with the aid of automated calibration to forecast future climate, with the results ingested by a hydrologic model to assess potential impacts on water yield.
