Drought is considered to be a normal feature of climate especially in tropical countries where occurrence of periods of dry weather during rainy season is common. Virtually droughts can occur in all climates and they can also be witnessed when the air temperatures are higher than the normal for a longer period that increases both evaporation and water deficit. 1. The first deals with the introduction to the topic, historical evidences of drought and famines in India. 2. The definition of droughts, criteria for classification of droughts, drought indices based on rainfall, climate derivatives and remote sensing are covered under two. 3. Information on climate change with respects to climate trends, projections on temperature and rainfall at global as well at national level, consequences of climate change on droughts are presented in there. 4. Approaches on drought monitoring, adopted by various countries, international cooperation in drought monitoring and drought monitoring mechanism in India are presented in four. Decision Support Systems and applications of GIS for drought monitoring are also covered in this . 5. World food production and its variability, the impact of phenomenal drought during 2009 on food grain production in different countries, impacts of droughts on livestock, milk and fisheries production are covered under five. 6.

Agricultural droughts affect whole societies, leading to higher food costs, threatened economies, and even famine. In order to mitigate such effects, researchers must first be able to monitor them, and then predict them; however no book currently focuses on accurate monitoring or prediction of these devastating kinds of droughts. To fill this void, the editors of Monitoring and Predicting Agricultural Drought have assembled a team of expert contributors from all continents to make a global study, describing biometeorological models and monitoring methods for agricultural droughts. These models and methods note the relationships between precipitation, soil moisture, and crop yields, using data gathered from conventional and remote sensing techniques. The coverage of the book includes probabilistic models and techniques used in America, Europe and the former USSR, Africa, Asia, and Australia, and it concludes with coverage of climate change and resultant shifts in agricultural productivity, drought early warning systems, and famine mitigation. This will be an essential collection for those who must advise governments or international organizations on the current scope, likelihood, and impact of agricultural droughts.

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.

Drought is an insidious hazard of nature. It originates from a deficiency of precipitation that results in a water shortage for some activity or some group. Africa has suffered the most dramatic impacts from drought during the past several decades the recent droughts in the southern and eastern portions of the continent are testimony to that fact. However, the vulnerability of all nations to extended periods of water shortage has been underscored again and again during this same time period. In the past decade alone, droughts have occurred with considerable frequency and severity in most of the developed and developing world. Significant parts of North and South America, Australia, Europe, and Asia have been plagued recently by extended periods of severe drought, often resulting in far-reaching economic, social, and environmental consequences. In the western United States, for example, vast areas are facing the prospects of a sixth or seventh consecutive year of drought in 1993. Concern by members ofthe scientific and policy communities about the inability of governments to respond in an effective and timely manner to drought and its associated impacts exists worldwide. Numerous "calls for action" for improved drought planning and management have been issued by national governments, professional organizations, intergovernmental organizations, nongovernmental organizations, and others. The United Nations' International Decade for Natural Disaster Reduction (lDNDR) is yet another example of an international call for action to reduce the impacts that result from drought and other natural hazards.

Drought is a slow-onset natural hazard that is often referred to as a creeping phenomenon. The challenge of monitoring drought’s onset and evolution, and identifying its termination or end is one that scientists, natural resource managers, and decision makers have been struggling with for decades. However, drought management must be aimed at reducing the risks of future drought events on economies, the environment, and the social fabric of regions. As with many countries, droughts are often managed as a crisis in Brazil, rather than events for which officials and communities proactively prepare. Although droughts are not new to Brazil, the recent spate of droughts in the poverty stricken semi-arid Northeast and the industrial hub of São Paulo in the Southeast has forced the country to think more seriously about finally changing its drought policies and management approaches. The book is told through the perspectives of the ministers and secretaries, state policy and technical officials, civil society organizations, and development practitioners that helped to facilitate the shift in paradigm in Brazil from crisis management and towards proactive management of droughts. It is written in a style that is appealing to both technical and non-technical audiences, and aims to provide a framework and lessons for other countries to consider when embarking upon similar efforts to improve their own drought policy and management systems.

Based on an International Workshop held in New Delhi, India, this work should be of interest to all organizations and agencies interested in improved risk management in agriculture. In many parts of the world, weather and climate are one of the biggest production risks and uncertainty factors impacting on agricultural systems performance and management. Both structural and non-structural measures can be used to reduce the impacts of the variability (including extremes) of climate resources on crop production.
