Hydro Climatic Extremes In The Anthropocene

This book explores how human civilization has contributed to changes in the Anthropocene, an era that marks a fundamental change in the way mankind has interacted with the Earth system. It examines the 21st century in the context of human development of water infrastructures, climate change impacts on freshwater resources, groundwater depletion, rising population, land use change, extreme events (droughts, floods, and wildfires). The implications of climate change impacts on environmental assets and the global water cycle are also highlighted. The book takes a pragmatically trans-disciplinary and holistic approach to the discussion of these issues, and the Earth system in the Anthropocene, drawing from a plethora of case studies. The capabilities of machine learning tools in satellite hydrology applications have been demonstrated as well as the feasibility of remote sensing data and innovative geospatial tools in environmental assessment. The book further showcases the multiple strengths and potential of new multi-disciplinary satellite radar programmes and geodetic missions, to measure and characterize extreme events, and their links to global climate, as well as in remote sensing of the environment. The aim is to provide innovative tools and a scientific framework that underpin our fundamental understanding of environmental systems, and the complexities of socio-hydrological systems in the Anthropocene. Policy issues have also been raised as an important aspect that can strengthen the management and administration of water resources, particularly in emerging economies where observational data is often lacking, limited, or difficult to access. It also highlights the lessons learned from freshwater hotspots (e.g., Lake Chad and Lake Urmia) where prolonged droughts and human activities have led to a permanent loss of surface water. It identifies the role of institutions and stakeholders in driving policies that underpins water management and climate change adaptation. The book articulates the novel applications of remote sensing tools as part of a monitoring framework that can alert stakeholders and the public sector to the dangers of mismanagement of freshwater in these hotspots and help facilitate water governance approaches. The book fills a critical gap in the multi-disciplinary aspect of planetary science, particularly in understanding the impacts of climate change and human actions on freshwater resources, as well as the stability of the Earth system.

Hydroclimatic Extremes in the Middle East and North Africa: Assessment, Attribution and Socioeconomic Impacts focuses on assessing the current situation of hydroclimatic extremes in the MENA region, with particular emphasis on dry and wet extreme events. The results of the rapidly changing atmospheric and oceanic situations of these extremes will be addressed, presenting examples for the environmental, socioeconomic, and cultural impacts of these events in the region and evaluating the current ability to monitor and adapt to such events, as well as exploring the potential use of advanced geospatial techniques in improving current understanding of these extreme events. The book utilizes a multidisciplinary approach with various state-of-the-art methods, approaches, and analytical techniques in environmental, meteorological, and hydrological sciences, providing case studies from the Middle East and North Africa. It will provide a solid basis for scientists to assess the validation of several research methods in the region and may be applicable to other regions as climate change continues to cause increasing aridity worldwide. The case studies presented will reflect the multifaceted character of hydrometeorological extremes in the region, with representative examples for the environmental, socioeconomic, and cultural impacts of climate change. Therefore, this book is a valuable source for climatologists, meteorologists, hydrologists, geographers, and water resources scientists. Thoroughly details the effects of climate variability in the Middle East and North Africa, a hotspot region of climate change vulnerability Examines changes in hydroclimatic extremes at different spatial scales, ranging from local assessments to investigations that cover the entire region Provides a comprehensive assessment of hydrometeorological feedback to current and future climate change in the MENA region Fills the current gap in the literature concerning the response of arid and semiarid regions to climate change, with particular emphasis on the MENA region

Climate theory dictates that core elements of the climate system, including precipitation, evapotranspiration, and reservoirs of atmospheric and soil moisture, should change as the climate warms, both in their means and extremes. A major challenge that faces the climate and hydrologic science communities is understanding the nature of these ongoing changes in climate and hydrology and the apparent anomalies that exist in reconciling their extreme manifestations. The National Research Council (NRC) Committee on Hydrologic Science (COHS) held a workshop on January 5-6, 2010, that examined how climate warming translates into hydrologic extremes like floods and droughts. The workshop brought together three groups of experts. The first two groups consisted of atmospheric scientists and hydrologists focused on the scientific underpinnings and empirical evidence linking climate variability to hydrologic extremes. The third group consisted of water managers and decision-makers charged with the design and operation of water systems that in the future must be made resilient in light of a changing climate and an environment of hydrologic extremes. Global Change and Extreme Hydrology summarizes the proceedings of this workshop. This report presents an overview of the current state of the science in terms of climate change and extreme hydrologic events. It examines the "conventional wisdom" that climate change will "accelerate" the hydrologic cycle, fuel more evaporation, and generate more precipitation, based on an increased capacity of a warmer atmosphere to hold more water vapor. The report also includes descriptions of the changes in frequency and severity of extremes, the ability (or inability) to model these changes, and the problem of communicating the best science to water resources practitioners in useful forums.

A graduate textbook on the interdisciplinary significance of hydroclimatology, explaining the relationship between the climate system and the hydrologic cycle.

Hydroclimatic extremes, such as floods and droughts, affect aspects of our lives and the environment including energy, hydropower, agriculture, transportation, urban life, and human health and safety. Climate studies indicate that the risk of increased flooding and/or more severe droughts will be higher in the future than today, causing increased fatalities, environmental degradation, and economic losses. Using a suite of innovative approaches this book quantifies the changes in projected hydroclimatic extremes and illustrates their impacts in several locations in North America, Asia, and Europe.
