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

Providing a reliable supply of water requires being prepared for water shortages of varying degree and duration. What can a municipal water supplier do to mitigate water shortages caused by drought? Preparing for drought and water shortages before they occur is the best defense. This manual will help water managers facing water shortages by illustrating how to employ tried-and-true strategies and tactics of drought mitigation, as well as new tools and methods. Managing water shortages involves temporarily reducing demand and finding alternate water to temporarily increase supply. There are options available to water managers to accomplish this. The manual provides a proven, seven-step process to anticipate and respond to water shortages through a structured planning process.

Recent advances in the modeling and remote sensing of droughts and floods Droughts and floods are causing increasing damage worldwide, often with devastating short- and long-term impacts on human society. Forecasting when they will occur, monitoring them as they develop, and learning from the past to improve disaster management is vital. Global Drought and Flood: Observation, Modeling, and Prediction presents recent advances in the modeling and remote sensing of droughts and floods. It also describes the techniques and products currently available and how they are being used in practice. Volume highlights include: Remote sensing approaches for mapping droughts and floods Physical and statistical models for monitoring and forecasting hydrologic hazards Features of various drought and flood systems and products Use by governments, humanitarian, and development stakeholders in recent disaster cases Improving the collaboration between hazard information provision and end users The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

The underlying concept of the paper is that the amount of precipitation required for the near-normal operation of the established economy of an area during some stated period is dependent on the average climate of the area and on the prevailing meteorological conditions both during and preceding the month or period in question. A method for computing this required precipitation is demonstrated.

Drought Challenges: Livelihood Implications in Developing Countries, Volume Two, provides an understanding of the occurrence and impacts of droughts for developing countries and vulnerable sub-groups, such as women and pastoralists. It presents tools for assessing vulnerabilities, introduces individual policies to combat the effects of droughts, and highlights the importance of integrated multi-sectoral approaches and drought networks at various levels. Currently, there are few books on the market that address the growing need for knowledge on these cross-cutting issues. As drought can occur anywhere, the systemic connections between droughts and livelihoods are a key factor in development in many dryland and agriculturally-dependent nations. - Connects the biophysical, social, economic, policy and institutional aspects of droughts across multiple regions in developing world - Analyzes policy linkages between government agencies, public institutions, NGOs, the private sector and communities - Includes a discussion of gender dimensions of drought and its impacts - Presents a multi-sectoral perspective, including the human dimensions of drought in developing countries

This book is open access under a Creative Commons license. This authoritative book presents the ever progressing state of the art in evaluating climate change strategies and action. It builds upon a selection of relevant and practical papers and presentations given at the 2nd International Conference on Evaluating Climate Change and Development held in Washington DC in 2014 and includes perspectives from independent evaluations of the major international organisations supporting climate action in developing countries, such as the Global Environment Facility. The first section of the book sets the stage and provides an overview of independent evaluations, carried out by multilateral development banks and development organisations. Important topics include how policies and organisations aim to achieve impact and how this is measured, whether climate change is mainstreamed into other development programs, and whether operations are meeting the urgency of climate change challenges. The following sections focus on evaluation of climate change projects and policies as they link to development, from the perspective of international organisations, NGO’s, multilateral and bilateral aid agencies, and academia. The authors share methodologies or approaches used to better understand problems and assess interventions, strategies and policies. They also share challenges encountered, what was done to solve these and lessons learned from evaluations. Collectively, the authors illustrate the importance of evaluation in providing evidence to guide policy change to informed decision-making.

Today the world is facing a greater water crisis than ever. Droughts of lesser magnitude are resulting in greater impact. Even in years with normal precipitation, water shortages have become widespread in both developing and developed nations, in humid as well as arid climates. When faced with severe drought, governments become eager to act. Unfort
