On top of a decade of exacerbated disaster loss, exceptional global heat, retreating ice and rising sea levels, humanity and our food security face a range of new and unprecedented hazards, such as megafires, extreme weather events, desert locust swarms of magnitudes previously unseen, and the COVID-19 pandemic. Agriculture underpins the livelihoods of over 2.5 billion people – most of them in low-income developing countries – and remains a key driver of development. At no other point in history has agriculture been faced with such an array of familiar and unfamiliar risks, interacting in a hyperconnected world and a precipitously changing landscape. And agriculture continues to absorb a disproportionate share of the damage and loss wrought by disasters. Their growing frequency and intensity, along with the systemic nature of risk, are upending people’s lives, devastating livelihoods, and jeopardizing our entire food system. This report makes a powerful case for investing in resilience and disaster risk reduction – especially data gathering and analysis for evidence informed action – to ensure agriculture’s crucial role in achieving the future we want.

A comprehensive guide to wind farm noise prediction, measurement, assessment, control and effects on people Wind Farm Noise covers all aspects associated with the generation, measurement, propagation, regulation and adverse health effects of noise produced by large horizontal-axis wind turbines of the type used in wind farms. The book begins with a brief history of wind turbine development and the regulation of their noise at sensitive receivers. Also included is an introductory chapter on the fundamentals of acoustics relevant to wind turbine noise so that readers are well prepared for understanding later chapters on noise measurements, noise generation mechanisms, noise propagation modelling and the assessment of the noise at surrounding residences. Key features: Potential adverse health effects of wind farm noise are discussed in an objective way. Means for calculating the noise at residences due to a wind farm prior to construction are covered in detail along with uncertainty estimates. The effects of meteorological conditions and other influences, such as obstacles, ground cover and atmospheric absorption, on noise levels at residences are explained. Quantities that should be measured as well as how to best measure them in order to properly characterise wind farm noise are discussed in detail. Noise generation mechanisms and possible means for their control are discussed as well as aspects of wind farm noise that still require further research to be properly understood. The book provides comprehensive coverage of the topic, containing both introductory and advanced level material.

An insider’s “indispensible” behind-the-scenes history of the transit system of San Francisco and surrounding counties (Houston Chronicle). In the first-ever history book about BART, longtime agency spokesman Michael C. Healy gives an insider’s account of the rapid transit system’s inception, hard-won approval, construction, and operations, warts and all. With a master storyteller’s wit and sharp attention to detail, Healy recreates the politically fraught venture to bring a new kind of public transit to the West Coast. What emerges is a sense of the individuals who made (and make) BART happen. From tales of staying up until 3:00 a.m. with BART pioneers Bill Stokes and Jack Everson to hear the election results for the rapid transit vote to stories of weathering scandals, strikes, and growing pains, this look behind the scenes of an iconic, seemingly monolithic structure reveals people at their most human—and determined to change the status quo. “The Metro. The T. The Tube. The world's most famous subway systems are known by simple monikers, and San Francisco's BART belongs in that class. Michael C. Healy delivers a tour-de-force telling of its roots, hard-fought approval, and challenging construction that will delight fans of American urban history.”—Doug Most, author of The Race Underground: Boston, New York, and the Incredible Rivalry That Built America's First Subway
