Available in PDF, EPUB and Kindle. Book excerpt: Remote Sensing of Drought: Innovative Monitoring Approaches presents emerging remote sensing-based tools and techniques that can be applied to operational drought monitoring and early warning around the world. The first book to focus on remote sensing and drought monitoring, it brings together a wealth of information that has been scattered throughout the literature and across many disciplines. Featuring contributions by leading scientists, it assembles a cross-section of globally applicable techniques that are currently operational or have potential to be operational in the near future. The book explores a range of applications for monitoring four critical components of the hydrological cycle related to drought: vegetation health, evapotranspiration, soil moisture and groundwater, and precipitation. These applications use remotely sensed optical, thermal, microwave, radar, and gravity data from instruments such as AMSR-E, GOES, GRACE, MERIS, MODIS, and Landsat and implement several advanced modeling and data assimilation techniques. Examples show how to integrate this information into routine drought products. The book also examines the role of satellite remote sensing within traditional drought monitoring, as well as current challenges and future prospects. Improving drought monitoring is becoming increasingly important in addressing a wide range of societal issues, from food security and water scarcity to human health, ecosystem services, and energy production. This unique book surveys innovative remote sensing approaches to provide you with new perspectives on large-area drought monitoring and early warning.

This book was released on 2008-11-11 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Droughts have formed an inseparable part of South Asian history and culture, with tragic consequences for a region that houses the greatest number of the world’s poor. However, this volume challenges the popular conception of drought, which is presented as an absolute shortage-scarcity with respect to an implicit understanding of the sufficiency of water. It highlights the fact that while available water supplies may be a given quantum, droughts are differentially experienced, politically inspired and socially constituted. It emphasises that the relative water scarcity needs to be appreciated, and argues that water scarcity means different things for diverse constituencies of water users. Policy prescriptions based on definitional premises will be flawed, as a misrepresentation of drought as merely water scarcity serves a political agenda. The editors and contributors of this volume critically evaluate the concept of drought, the way it is defined, its origin/derivation, and the purposes/interests it serves. This book is broadly divided into three major sections: the thematic section, country overviews, and case studies. Through these, it attempts to: - Understand the concept of drought. - Map diversity in drought situations across South Asia. - Identify responses to drought. - Outline viable options for more integrated approaches to drought policies and mitigation strategies. - Initiate a process of dialogue on a more comprehensive public policy for drought management. Comprehensive, thought-provoking, informative, and featuring new research data, this collection will provide policy makers and professionals with the opportunity to discuss and debate policies for sustainable livelihood support systems and drought management. It would also be an invaluable source of information for students and teachers working in the fields of Water and Natural Resource Management, Environmental Planning, Agricultural Economics, Rural Development, Public Policy and Public Administration.

Available in PDF, EPUB and Kindle. Book excerpt: The study examines the global pattern and impacts of droughts through mapping several drought-related characteristics - either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated that the African continent is lagging behind the rest of the world on many indicators related to drought-preparedness and that agricultural economies, overall, are much more vulnerable to adverse societal impacts of meteorological droughts. The study also examines the ability of various countries to satisfy their water needs during droughts using storage-related indices.

This book was released on 2010 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drought is a recurrent extreme climate event with tremendous hazard for every specter of natural environment and human lives. Drought analysis usually involves characterizing drought severity, duration and intensity. Similar to most of the hydrological problems, such characteristic variables are usually not independent. Copula, as a model of multivariate distribution, widely used in finance, actuarial analysis, has won increasingly popularity in hydrological study. Here, the study has two major focuses: (1) fit drought characteristics from Streamflow Drought Index (SDI) or Standardized Runoff Index (SRI) to appropriate copulas, then using fitted copulas to estimate conditional drought severity distribution and joint return periods for both historical time period 1920-2009 and future time period 2020-2090. SDI is calculated based on long term observed streamflow while SRI is based on simulated future runoff. Parameters estimation of marginal distribution and copulas are provided, with goodness fit measures as well; (2) investigate the effects of climate change on the frequency and severity of droughts. In order to quantify the impact, three drought indices have been proposed for this study to characterize the drought duration, severity and intensity changes under the climate change in Upper Klamath River Basin. Since drought can be defined as different types, such as meteorological drought, agricultural drought, hydrological drought and social economical drought, this study chooses Standardized Precipitation Index (SPI), Palmer Drought Severity Index (PDSI) and Surface Water Supply Index (SWSI) to estimate the meteorological, agricultural and hydrological drought, respectively. Climate change effects come from three sources: the inherent reason, the human activity and the GCMs uncertainties. Therefore, the results show the long term drought condition by calculating yearly drought indices, and compared in three ways: First, compare drought characteristics of future time periods with base period; second, show the uncertainties of three greenhouse gas emission scenarios; third, present the uncertainties of six General Circulation Models (GCMs).
