In the twenty-first century, droughts have become more common and more prolonged in many areas around the world. Among other effects, droughts have a significant impact on the crops that feed us. This book explores the topics of drought and crop failure throughout history and in modern times. Through detailed photographs, sidebars, and Did You Know boxes, it presents a vivid overview of droughts and crop failure around the world, examines the causes of such events, and studies key people and organizations creating new technologies that battle droughts and crop failure. Finally, this book delves into the technologies themselves, exploring their usefulness today and considering how they might be improved upon in the future.

People around the globe are becoming increasingly aware that our use of the land has an effect on the environment in which we live. Global warming is seen as a major threat to the well-being of the world's communities. Fear abounds, but does anyone really know what is going on? Will human activity make things worse? In this 1994 book, the author examines the relationship between society and climate change. With contributions from colleagues in the worst hit areas of the world, the author shows how some patterns of land use can make the problems worse; increasing the risk of droughts and associated food shortages. This book will help scientists and researchers assess our impact on the planet and consider our ability to respond to the consequences of future environmental change.

Timely and accurate agricultural impact assessments for droughts are critical for designing appropriate interventions and policy. These assessments are often ad hoc, late, or spatially imprecise, with reporting at the zonal or regional level. This is problematic as we find substantial variability in losses at the village-level that are missing when reporting even at the zonal level. In this paper we propose a new data fusion method combining remotely-sensed data with agricultural survey data that might address these limitations. We apply the method to Ethiopia, which is regularly hit by droughts and is a substantial recipient of ad hoc imported food aid. We then utilize remotely-sensed data obtained near mid-season to predict substantial crop losses of greater than or equal to 25 percent due to drought at the village level for five primary cereal crops. We train machine learning models to predict the likelihood of losses and explore the most influential variables. On independent samples, the models identify substantial drought loss cases with up to 70 percent accuracy by mid- to late-September. We believe the proposed models could be used to help monitor and predict yields for disaster response teams and policy makers, particularly with further development of the models and integration of newly available high resolution remotely-sensed data, such as the Harmonized Landsat Sentinel (HLS) data set

Recognizing drought as a characteristic feature of the North American climate, the contributors to this volume seek to organize available evidence of both prehistoric and modern drought events and to provide information on the severity of droughts, especially those which have occurred since weather records have been kept. The impacts of modern-era droughts on production and the potential impact of future droughts on the productivity of North American agriculture are examined. The authors explore the effeats of past droughts on the social, cultural, and political life of the population; the possible effects of drought on today's energy- and techno logy-intensive society; and the ramifications of drought for the national economy. The social and political strategies that local, state, and federal governments may use to meliorate the effects of drought are also considered, as are some possible technological defenses against drought—weather modification, expanded irrigation, new techniques of water harvesting and storage, and new agronomic adaptations. Finally, the critical question of whether future droughts can be forecast is examined.

At last, integrated management of drought on farms is dealt with in one comprehensive book. Although drought is a highly variable, near-universal natural phenomenon which has repercussions on a country's water and food supplies and many other sectors of the economy, there are many ways of avoiding, resisting and mitigating the effects of drought. Pro-active preparedness entails using the principles of risk management to upgrade the drought resistance of a farm systematically, and to have auxiliary contingency plans at the ready for use during unusually long droughts. The book provides tools for these strategies as it covers the management of water, soils, crops, rangeland, fodder and livestock, and many other drought-related topics. Audience: This book will be an important source of information for university and college staff and students in agricultural sciences, water and land use, environmental management, geography and risk management, and also farmers, agricultural advisors and policy makers.
