Book Description
This report describes the development of the near real-time drought monitoring and reporting system for the region, which currently includes Afghanistan, Pakistan and western parts of India. The system is based on drought-related indices derived from high-resolution remote-sensing data (MODIS). The unique feature of the study is the development of regression relationships between drought-related indices obtained from MODIS and AVHRR data, which have different pixel-resolution and optical characteristics. The goal is to make the system available, via Internet, to all stakeholders in the region.

Book Description
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.

Book Description
Frequent drought events have recently occurred in different Mediterranean regions. These have highlighted a general inadequacy of the current strategies applied to mitigate negative impacts of such phenomenon. This book provides various methods of drought monitoring at different spatial scales, as well as innovative drought forecasting techniques based on stochastic approaches. Besides common drought indices (i.e. SPI), new agrometeorological indices are proposed.

Book Description
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.

Book Description
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.
