In order to provide water security in the twenty-first century, there is universal agreement that a continuation of current policies and extrapolation of trends is not an option. Also clear is that from both water supply and development perspectives, the world's arid and semi-arid regions are those currently and potentially experiencing the highest

Dry summer, wet winter climate? This is your must have plant guide. Selecting plants suited to your climate is the first step toward a thriving, largely self-sustaining garden that connects with and supports the natural world. With gentle and compelling text and stunning photographs of plants in garden settings, Gardening in Summer-Dry Climates by Nora Harlow and Saxon Holt is a guide to native and climate-adapted plants for summer-dry, winter-wet climates of North America's Pacific coast. Knowing what these climates share and how and why they differ, you can choose to make gardens that maintain and expand local and regional biodiversity, take little from the earth that is not returned, and welcome and accommodate the presence of wildlife. With global warming, it is now even more critical that we garden in tune with climate.

Almost all homes, apartments, and commercial buildings will experience leaks, flooding, or other forms of excessive indoor dampness at some point. Not only is excessive dampness a health problem by itself, it also contributes to several other potentially problematic types of situations. Molds and other microbial agents favor damp indoor environments, and excess moisture may initiate the release of chemical emissions from damaged building materials and furnishings. This new book from the Institute of Medicine examines the health impact of exposures resulting from damp indoor environments and offers recommendations for public health interventions. Damp Indoor Spaces and Health covers a broad range of topics. The book not only examines the relationship between damp or moldy indoor environments and adverse health outcomes but also discusses how and where buildings get wet, how dampness influences microbial growth and chemical emissions, ways to prevent and remediate dampness, and elements of a public health response to the issues. A comprehensive literature review finds sufficient evidence of an association between damp indoor environments and some upper respiratory tract symptoms, coughing, wheezing, and asthma symptoms in sensitized persons. This important book will be of interest to a wide-ranging audience of science, health, engineering, and building professionals, government officials, and members of the public.

Scholars and researchers have long believed that the ability to irrigate is crucial to the development of civilizations. In this book, archaeologist Patrick Kirch challenges this "hydraulic hypothesis" and provides a more accurate and detailed account of the role of "wet" and "dry" cultivation systems in the development of complex sociopolitical structures. Examining research on cultural adaptation and ecology in Western Polynesia and utilizing extensive data from a variety of important South Pacific sites, Kirch not only reveals how particular systems of production developed within the constraints imposed by environmental conditions, but also explores the tension that arises between contrasting productive systems with differential abilities to produce surplus. He shows that the near total neglect of short-fallow dryland cultivation, as well as arboriculture, or tree-cropping, has seriously distorted the picture that archaeologists and anthropologists have of agricultural intensification and its relation to complex social structure. This work, likely to become a classic, will be central to all future discussions of the ecology and politics of agricultural intensification.

Developed by three experts to coincide with geology lab kits, this laboratory manual provides a clear and cohesive introduction to the field of geology. Introductory Geology is designed to ease new students into the often complex topics of physical geology and the study of our planet and its makeup. This text introduces readers to the various uses of the scientific method in geological terms. Readers will encounter a comprehensive yet straightforward style and flow as they journey through this text. They will understand the various spheres of geology and begin to master geological outcomes which derive from a growing knowledge of the tools and subjects which this text covers in great detail.
