Drawing on a host of scientific studies, this text explores how rising levels of CO2 in the atmosphere have impacted water in plants and soils. It discusses drought, the soil-plant-atmosphere continuum, the soil atmosphere, root growth, and variable oxygen concentration of soil. The book also covers the use of carbon isotope ratios in plant science, stomatal conductance and density, transpiration and evapotranspiration, water use efficiency, C4 photosynthesis, plant anatomy, phenology, and measures of plant growth. More than 200 high quality figures illustrate the concepts discussed.

In past decades and in association with a continuing global industrial development, the global atmospheric concentration of carbon dioxide has been rising. Among the many predictions made concerning this disturbing trend is global warming sufficient to melt polar ice-caps thereby dramatically altering existing shorelines. This book will help fill an obvious gap in the carbon dioxide debate by substituting date for speculation.* * Includes contributions from leading authorities around the world* Serves as a companion to Carbon Dioxide and Terrestrial Ecosystems* The first book of its kind to explore evolutionary responses of both populations and communities to elevated carbon dioxide

The question of whether the earth's climate is changing in some significant human-induced way remains a matter of much debate. But the fact that climate is variable over time is well known. These two elements of climatic uncertainty affect water resources planning and management in the American West. Managing Water Resources in the West Under Conditions of Climate Uncertainty examines the scientific basis for predictions of climate change, the implications of climate uncertainty for water resources management, and the management options available for responding to climate variability and potential climate change.

Between 1958 and 2008, the CO2 concentration in the atmosphere increased from 316 to 385 ppm. Continued increases in CO2 concentration will significantly affect long-term climate change, including variations in agricultural yields. Focusing on this critical issue, Elevated Carbon Dioxide: Impacts on Soil and Plant Water Relations presents research

Carbon dioxide (CO2) levels are rising globally at a rapid pace, on track to surpass 550 parts per million (ppm) by midcentury. Studies have found that, when grown under elevated CO2 concentrations of 546–586 ppm, many food crops—including wheat, rice, barley, and soybeans—have lowered concentrations of nutrients, including many that are important for overall health, such as iron, zinc, and protein. Elevated CO2 also affects both the quantity and quality of forage, thereby affecting animal performance and production and, consequently, the availability of nutrients from animal-source foods, such as meat, milk, and eggs. This loss of dietary nutrients in foods could translate to increased nutritional deficiency for hundreds of millions of people already on the brink of deficiency—mainly developing countries in Asia, the Middle East, and North Africa based on dietary preferences for the commodities most affected. This policy note examines the link between rising CO2 levels and declining nutritional content for a number of major crops, as well as forage. The discussion includes a comparison of the varying effects by crop, and strategies to address this challenge in the context of climate change.

This book focuses on the interactive effects of environmental stresses with plant and ecosystem functions, especially with respect to changes in the abundance of carbon dioxide. The interaction of stresses with elevated carbon dioxide are presented from the cellular through whole plant ecosystem level. The book carefully considers not only the responses of the above-ground portion of the plant, but also emphasizes the critical role of below-ground (rhizosphere) components (e.g., roots, microbes, soil) in determining the nature and magnitude of these interactions.* Will rising CO2 alter the importance of environmental stress in natural and agricultural ecosystems?* Will environmental stress on plants reduce their capacity to remove CO2 from the atmosphere?* Are some stresses more important than others as we concern ourselves with global change?* Can we develop predictive models useful for scientists and policy-makers?* Where should future research efforts be focused?
