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

We see the stories in the newspaper nearly every day: a drug hailed as a breakthrough treatment turns out to cause harmful side effects; controls implemented to reduce air pollution are shown to generate hazardous solid waste; bans on dangerous chemicals result in the introduction of even more risky substitutes. Could our efforts to protect our health and the environment actually be making things worse? In Risk versus Risk, John D. Graham, Jonathan Baert Wiener, and their colleagues at the Harvard Center for Risk Analysis marshal an impressive set of case studies which demonstrate that all too often our nation's campaign to reduce risks to our health and the environment is at war with itself.

This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines.

The World Energy Outlook series is a leading source of strategic insight on the future of energy and energy-related emissions, providing detailed scenarios that map out the consequences of different energy policy and investment choices. This year's edition updates the outlooks for all fuels, technologies and regions, based on the latest market data, policy initiatives and cost trends. In addition, the 2019 report tackles some key questions in depth: (i) What do the shale revolution, the rise of liquefied natural gas, the falling costs of renewables and the spread of digital technologies mean for tomorrow's energy supply?; (ii) How can the world get on a pathway to meet global climate targets and other sustainable energy goals?; (iii) What are the energy choices that will shape Africa's future, and how might the rise of the African consumer affect global trends?; (iv) How large a role could offshore wind play in the transformation of the energy sector?; (v) Could the world's gas grids one day deliver low-carbon energy?

V.1. History, world distribution, botany, and varieties. v.2. Anatomy, physiolo gy, genetics, and reproduction. v.3. Production technology. v.4. Crop protectio n. v.5. Crop, protection, postharvest technology, and early history of citrus r esearch in California.

Consideration of the interactions between decisions made at one point in the supply chain and its effects on the subsequent stages is the core concept of a systems approach. Postharvest Handling is unique in its application of this systems approach to the handling of fruits and vegetables, exploring multiple aspects of this important process through chapters written by experts from a variety of backgrounds.Newly updated and revised, this second edition includes coverage of the logistics of fresh produce from multiple perspectives, postharvest handing under varying weather conditions, quality control, changes in consumer eating habits and other factors key to successful postharvest handling.The ideal book for understanding the economic as well as physical impacts of postharvest handling decisions.Key Features:*Features contributions from leading experts providing a variety of perspectives*Updated with 12 new chapters*Focuses on application-based information for practical implementation*System approach is unique in the handling of fruits and vegetables
