Disasters arise from the convergence of natural and social forces. Earthquakes, cyclones, floods, droughts, and other catastrophic events disproportionately affect the most vulnerable people, whether the poor in wealthy countries or the inhabitants of less developed countries. In a warming world, climate-related disasters threaten to become even more hazardous. This primer provides readers with a fundamental understanding of disasters and their consequences. John C. Mutter and Sonali Deraniyagala—a natural scientist and an economist—share their expertise in straightforward language, showing why an interdisciplinary approach is necessary to understand the causes and effects of these multifaceted events. This book first explains the natural science of why and how disasters occur and then investigates their significance for economic development across communities and countries, focusing on growth, inequality, and reconstruction. It features a wide range of global case studies, including earthquakes in Turkey and Haiti, hurricanes in the United States, drought in Ethiopia, and cyclones in Myanmar and Bangladesh. Disasters and Development will be useful for undergraduate and graduate courses, and it is relevant and accessible to practitioners and other interested readers.
