Natural Decadal Climate Variability: Societal Impacts is an important work for understanding the natural decadal climate variability (DCV), a phenomenon which has made long lasting impacts on civilizations, especially on water availability and agriculture. This book comprehensively covers multiyear to decadal variations in instrument measured precipitation and temperature, water availability and river flows, crop production, agricultural irrigation, inland water-borne transportation, hydroelectricity generation, and fish and crustacean captures since the 1960s. A longer term perspective is provided with the use of multi-century data on dry and wet epochs based on tree ring information, and corroborating evidence from other literature. This valuable work will benefit climate scientists, meteorologists, hydrologists, agronomists, water transportation planners, resource economists, policymakers, professors, and graduate students and anyone else who has an interest in learning how natural climate phenomena has influenced societies for at least the past 1000 years.
