Sponsored by the Urbanization Effects on Groundwater Task Committee of the Groundwater Hydrology Committee of the Groundwater Council of the Environmental and Water Resources Institute of ASCE. What are the regional differences in stormwater and wastewater management technology approachesØto urbanization? How can wetland extent and function be incorporated as an integral part of urban infrastructure systems, including effects on groundwater level? Addressing questions such as these, this book presents sustainable systems engineering technologies and applies them to the management of water in urban areas. To promote sustainable management of water, chapters examine the interactions among energy, environment, ecology, and socioeconomic paradigms and describe the challenges and opportunities facing engineers, scientists, and policymakers. Topics fall into four broad categories: water supply and pollution prevention; stormwater management with regional infiltration technologies; Ø wastewater treatment and disposal with nutrient removal; and Ø low impact development with landscape architecture technologies. Ø Within these categories, chapters range from the fundamental theory to physical, chemical, and biological processes, to the coupled human and natural environment, to the representation of simulated evolutionary pathways. This volume makes a strong case for sustainable development and management and helps to expose how sensitive key water quantity and quality management targets are to urban development.

Climate change is expected to modify the hydrological cycle and affect freshwater resources. Groundwater is a critical source of fresh drinking water for almost half of the world’s population and it also supplies irrigated agriculture. Groundwater is also important in sustaining streams, lakes, wetlands, and associated ecosystems. But despite this, knowledge about the impact of climate change on groundwater quantity and quality is limited. Direct impacts of climate change on natural processes (groundwater recharge, discharge, storage, saltwater intrusion, biogeochemical reactions, chemical fate and transport) may be exacerbated by human activities (indirect impacts). Increased groundwater abstraction, for example, may be needed in areas with unsustainable or contaminated surface water resources caused by droughts and floods. Climate change effects on groundwater resources are, therefore, closely linked to other global change drivers, including population growth, urbanization and land-use change, coupled with other socio-economic and political trends. Groundwater response to global changes is a complex function that depends on climate change and variability, topography, aquifer characteristics, vegetation dynamics, and human activities. This volume contains case studies from diverse aquifer systems, scientific methods, and climatic settings that have been conducted globally under the framework of the UNESCO-IHP project Groundwater Resources Assessment under the Pressures of Humanity and Climate Change (GRAPHIC). This book presents a current and global synthesis of scientific findings and policy recommendations for scientists, water managers and policy makers towards adaptive management of groundwater sustainability under future climate change and variability.

The uncontrolled utilization of natural resources to supply to the water demands of the ever-growing population has brought about worldwide scarcity. The supply shortage has resulted in conflicts between countries, created prolonged drought, closing of industrial units, shifting of local inhabitants etc. The abnormality in climatic patterns due to global warming has only enhanced the uncertainties. Unregulated discharge of waste water into fresh water resources is also polluting the available water resources and making them non-utilizable. That is why the discrepancy between water supply and demand is slowly but steadily becoming a problem, which may lead to conflict and inequality all over the world. The present investigation is an attempt to find the impact of urbanization in the face of climatic uncertainties on water shortage or scarcity. How is climate responsible? What urbanization factors have an influence on the extent of shortages? What is the role of the socio-economic status of the inhabitants? Industrialization? Consumption pattern? Each of the causes and effects were analyzed with the help of data from a climate model, which was then fed into a hydrologic model. The hydrologic output data was then put into various other novel simulation platforms to predict the uncertainties that can be caused by urbanization in various sectors of the regions of interest. The impact was calculated based on IPCC recommended climatic and five distinct urbanization scenarios. The study results will help to predict what is in store of those living in the developing countries. Possible mitigation measures are also discussed.

Urban Climates is the first full synthesis of modern scientific and applied research on urban climates. The book begins with an outline of what constitutes an urban ecosystem. It develops a comprehensive terminology for the subject using scale and surface classification as key constructs. It explains the physical principles governing the creation of distinct urban climates, such as airflow around buildings, the heat island, precipitation modification and air pollution, and it then illustrates how this knowledge can be applied to moderate the undesirable consequences of urban development and help create more sustainable and resilient cities. With urban climate science now a fully-fledged field, this timely book fulfills the need to bring together the disparate parts of climate research on cities into a coherent framework. It is an ideal resource for students and researchers in fields such as climatology, urban hydrology, air quality, environmental engineering and urban design.

Urbanization is a global phenomenon and the book emphasizes that this is not just a social-technological process. It is also a social-ecological process where cities are places for nature, and where cities also are dependent on, and have impacts on, the biosphere at different scales from local to global. The book is a global assessment and delivers four main conclusions: Urban areas are expanding faster than urban populations. Half the increase in urban land across the world over the next 20 years will occur in Asia, with the most extensive change expected to take place in India and China Urban areas modify their local and regional climate through the urban heat island effect and by altering precipitation patterns, which together will have significant impacts on net primary production, ecosystem health, and biodiversity Urban expansion will heavily draw on natural resources, including water, on a global scale, and will often consume prime agricultural land, with knock-on effects on biodiversity and ecosystem services elsewhere Future urban expansion will often occur in areas where the capacity for formal governance is restricted, which will constrain the protection of biodiversity and management of ecosystem services

Academic Paper from the year 2014 in the subject Geography / Earth Science - Meteorology, Aeronomy, Climatology, language: English, abstract: Climate change poses uncertainties to the supply and management of water resources. The Intergovernmental Panel on Climate Change (IPCC) estimates that the global mean surface temperature has increased 0.6 0.2 oC since 1861, and predicts an increase of 2 to 4 oC over the next 100 years. Temperature increases also affect the hydrologic cycle by directly increasing evaporation of available surface water and vegetation transpiration. Consequently, these changes can influence precipitation amounts, timings and intensity rates, and indirectly impact the flux and storage of water in surface and subsurface reservoirs (i.e., lakes, soil moisture, groundwater). In addition, there may be other associated impacts, such as sea water intrusion, water quality deterioration, potable water shortage, etc. While climate change affects surface water resources directly through changes in the major long-term climate variables such as air temperature, precipitation, and evapotranspiration, the relationship between the changing climate variables and groundwater is more complicated and poorly understood. The greater variability in rainfall could mean more frequent and prolonged periods of high or low groundwater levels, and saline intrusion in coastal aquifers due to sea level rise and resource reduction. Groundwater resources are related to climate change through the direct interaction with surface water resources, such as lakes and rivers, and indirectly through the recharge process. The direct effect of climate change on groundwater resources depends upon the change in the volume and distribution of groundwater recharge. Therefore, quantifying the impact of climate change on groundwater resources requires not only reliable forecasting of changes in the major climatic variables, but also accurate estimation of groundwater recharge.

This manual comprises a holistic view of urban runoff quality management. For the beginner, who has little previous exposure to urban runoff quality management, the manual covers the entire subject area from sources and effects of pollutants in urban runoff through the development of management plans and the design of controls. For the municipal stormwater management agency, guidance is given for developing a water quality management plan that takes into account receiving water use objectives, local climatology, regulation, financing and cost, and procedures for comparing various types of controls for suitability and cost effectiveness in a particular area. This guidance will also assist owners of large-scale urban development projects in cost-effectively and aesthetically integrating water quality control to the drainage plan. The manual is also directed to designers who desire a self-contained unit that discusses the design of specific quality controls for urban runoff.

This book provides a unique synthesis of concepts and tools to examine natural resource, socio-economic, legal, policy and institutional issues that are important for managing urban growth into the future. The book will particularly help the reader to understand the current issues and challenges and develop strategies and practices to cope with future pressures of urbanisation and peri-urban land, water and energy use challenges. In particular, the book will help the reader to discover underlying principles for the planning of future cities and peri-urban regions in relation to: (i) Balanced urban development policies and institutions for future cities; (ii) Understanding the effects of land use change, population increase, and water demand on the liveability of cities; (iii) Long-term planning needs and transdisciplinary approaches to ensure the secured future for generations ahead; and (iv) Strategies to adapt the cities and land, water and energy uses for viable and liveable cities. There are growing concerns about water, food security and sustainability with increased urbanisation worldwide. For cities to be liveable and sustainable into the future there is a need to maintain the natural resource base and the ecosystem services in the peri-urban areas surrounding cities. This need is increasing under the looming spectre of global warming and climate change. This book will be of interest to policy makers, urban planners, researchers, post-graduate students in urban planning, environmental and water resources management, and managers in municipal councils.

Groundwater contributes to the sustainable development of many Asian cities by providing water for domestic, industrial and agricultural uses and regulating ecosystem flows. However, groundwater has not always been properly managed, which often has resulted in depletion and degradation of the resource. Groundwater Environment in Asian Cities presents the up-to-date scientific knowledge on groundwater environment in fourteen Asian cities using Driver-Pressure-State-Impact-Response (DPSIR) framework. In detail the book presents the facts and figures of groundwater dependency, problems related to groundwater over exploitation, implementation of various policy instruments and management practices and their results in selected fourteen Asian cities, namely; Bandung (Indonesia), Bangkok (Thailand), Beijing (China), Bishkek (Kyrgyzstan), Chitwan (Nepal), Delhi (India), Dili (East Timor), Ho Chi Minh (Vietnam), Hyderabad (India), Khulna (Bangladesh), Lahore (Pakistan), Seoul (South Korea), Tokyo (Japan), and Yangon (Myanmar). The book provides the one-step platform to get sufficient details about groundwater aquifers, hydrogeology, groundwater status, impacts on groundwater environment and responses (technology, policy, institutional, etc.) deployed in the case studies cities, and therefore, provides a snap-shot of Asian groundwater environments. The theoretical background of the topics discussed along with the case studies help the readers understand the similarities and differences about the status of groundwater development and use in each city. In addition, the information in the book will serve as a baseline for other research such as mitigation of groundwater related problems (e.g., land subsidence), impact of climate change on groundwater, and importance of groundwater for implementing sustainable development goals in future. Presents a framework for evaluating groundwater environment in urban environments Includes case studies and local examples from a broad geographical range of urban environments from virtually every region in Asia, including Bandung, Bangkok, Delhi, Bishkek, Beijing and Tokyo The book will be a valuable resource for groundwater adversaries in the scientific, decision-making and end-user communities, particularly for understanding and assessing state of groundwater resources in the region as well as learning from the responses practiced so far (Dr. Linda Anne Stevenson, APN) The contents in this book are very much useful for informed decision-making for protecting groundwater environemntand therefore contributes in making invisible visible (Dr. Neno Kukuric, IGRAC) With concrete examples and lessons for readers, this book responds to the call for comprehensive research and studies, the implementation of new science-based methodologies and endorsement of principles for groundwater resources management and cities (Dr. Aureli Alice, UNESCO-IHP) As a “Regional Hub for Groundwater Management in the Asia Pacific Region , IGES finds this book as a very much useful reference for knowledge hub partners, groundwater managers, academic institutions, research scholars, and international organizations working in the areas of groundwater in Asia and beyond (Dr. Hideyuki Mori, IGES)

Urbanization affects wetlands in direct and indirect ways. Over the past several decades it has become increasingly apparent that unmanaged runoff is the primary threat to the country's watershed resources. Wetlands and Urbanization: Implications for the Future is the result of a ten year research project focused on the understanding and managing the impacts of urban stormwater on wetlands. The book documents the background, methods, and results of the research and uses the information to draw conclusions about managing wetland ecosystems in urban areas. The project culminates in a set of comprehensive guidelines for the management of wetland hydrology. While the focus of this research is regional in nature, its applications are broad. First, the research shows how to measure and assess the impact of urbanization on wetlands. Secondly, it presents scientific approaches available for use in an integrated assessment of wetland condition. And thirdly, it provides guidelines for biomonitoring wetlands using multiple indicators. Wetlands and Urbanization presents an integrated watershed approach to the scientific evaluation of the impact of landscape urbanization on wetland functions. It associates the source of impact (the landscape) with the sink (the wetland), relates findings to implications for future planning and management of watersheds and provides a model for future comprehensive investigations of wetland impacts from urbanization.
