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.

Drought risk management involves three pillars: drought early warning, drought vulnerability and risk assessment, and drought preparedness, mitigation, and response. This book collects in one place a description of all the key components of the first pillar, and describes strategies for fitting these pieces together. The best modern drought early warning systems incorporate and integrate a broad array of environmental information sources: weather station observations, satellite imagery, land surface and crop model simulations, and weather and climate model forecasts, and analyze this information in context-relevant ways that take into account exposure and vulnerability. Drought Early Warning and Forecasting: Theory and Practice assembles a comprehensive overview of these components, providing examples drawn from the Famine Early Warning Systems Network and the United States Drought Monitor. This book simultaneously addresses the physical, social, and information management aspects of drought early warning, and informs readers about the tools, techniques, and conceptual models required to effectively identify, predict, and communicate potential drought-related disasters. This book is a key text for postgraduate scientists and graduate and advanced undergraduate students in hydrology, geography, earth sciences, meteorology, climatology, and environmental sciences programs. Professionals dealing with disaster management and drought forecasting will also find this book beneficial to their work. Describes and discusses the strategies and components used in effective and integrated 21st century drought early warning systems Provides a one-stop-shop that describes in one book the observations, models, forecasts, indices, social context, and theory used in drought early warning Identifies the latest tools and approaches used to monitor and forecast drought, sources of predictive skill, and discusses the technical and theoretical details required to use these tools and approaches in a real-world setting

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.

Drought is the most costly hazard among all natural disasters. Despite the significant improvements in drought modeling over the last decade, accurate provisions of drought conditions in a timely manner is still one of the major research challenges. In order to improve the current drought monitoring and forecasting skills, this study presents a hybrid system with a combination of remotely sensed data assimilation based on particle filtering and a probabilistic drought forecasting model. Besides the proposed drought monitoring system through land data assimilation, another novel aspect of this dissertation is to seek the use of data assimilation to quantify land initial condition uncertainty rather than relying entirely on the hydrologic model or the land surface model to generate a single deterministic initial condition. Monthly to seasonal drought forecasting products are generated using the updated initial conditions. The computational complexity of the distributed data assimilation system required a modular parallel particle filtering framework which was developed and allowed for a large ensemble size in particle filtering implementation. The application of the proposed system is demonstrated with two case studies at the regional (Columbia River Basin) and the Conterminous United States. Results from both synthetic and real case studies suggest that the land data assimilation system significantly improves drought monitoring and forecasting skills. These results also show how sensitive the seasonal drought forecasting skill is to the initial conditions, which can lead to better facilitation of the state/federal drought preparation and response actions.

Drought and heat waves resulted in economic losses of $171 billion in the United States between 1980 and 2007, losses which emphasize the need for a proactive risk management approach for drought management. The motivation for this study is to develop and evaluate approaches and tools to improve drought monitoring and prediction in the U.S., through the use of advanced macroscale hydrologic models and weather/climate forecasts. The value of a macroscale hydrologic model-based Drought Monitoring System (DMS) was assessed in terms of its potential use as a drought-monitoring tool in Washington State. The results show that had the DMS indicators been available during four major droughts from 1976 on, they would have detected the onset and recovery of drought conditions, in many cases, up to four months before state drought declarations. Subsequently, the relative contributions of the sources of seasonal hydrologic and drought predictability (i.e., initial hydrologic conditions (IHCs) and climate forecast skill) were identified over the Contiguous U.S. (CONUS). This analysis indicated that improvement in hydrologic forecasts can result from better knowledge of IHCs in the western U.S. during spring and summer. On the other hand, improved climate forecast skill is needed to improve hydrologic and drought forecast skill in most parts of the northeastern and southeastern U.S. throughout the year and in the western U.S. during fall and winter months. The effect of medium range weather forecast skill (i.e. 14 days) on seasonal hydrologic/drought forecast skill was then investigated. The analysis indicated that medium-range weather forecasts have the potential to improve seasonal hydrologic forecast skill beyond the initial hydrologic condition effect at 1-month leadtime and, in some cases, up to 3 months. Finally, the value of dynamical in contrast with statistical downscaling of seasonal climate forecasts was evaluated in terms of resulting improvement in seasonal hydrologic forecast skill. This analysis identified that dynamical downscaling does somewhat increase the seasonal hydrologic forecast skill over some parts of the Northwestern and North Central U.S.
