Written in easy to follow language, the book presents cutting-edge agriculturally relevant plant biotechnologies and applications in a manner that is accessible to all. This book introduces the scope and method of plant biotechnologies and molecular breeding within the context of environmental analysis and assessment, a diminishing supply of productive arable land, scarce water resources and climate change. Authors who have studied how agro ecosystems have changed during the first decade and a half of commercial deployment review effects and stress needs that must be considered to make these tools sustainable.

Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

An expanded, new and improved American Environmental History textbook for everyone! After years of teaching Environmental History at a major East Coast University without a textbook, Dr. Dan Allosso decided to take matters into his own hands. The result, American Environmental History, is a concise, comprehensive survey covering the material from Dan's undergraduate course. What do people say about the class and the text? "This was my first semester and this course has created an incredible first impression. If all of the courses are this good, I am going to really enjoy my time here. The course has completely changed the way I look at the world." (Student in 2014 class) "One of the few classes I'm really sad is ending, the subject matter is fascinating and Dan is a great guide to it. His approach should be required of all students as it teaches an appreciation for a newer and better way of living." (Student in 2014 class) "Allosso's lectures are fantastic. The best I have ever had. So impressed. The material is always extremely interesting and well-presented." (Student in 2015 class) "It is just a perfect course that I think should be mandatory if we want to save our planet and live responsibly." (Student in 2015 class) "A rare gem for an IB ESS teacher or any social studies teacher looking for an 11th or 12th grade supplementary text that aims to provide an historical context for the environmental reality in America today. Highly recommended." (District Curriculum Coordinator, 2016) "I was so impressed with this material that I am using it as a supplement for a course I teach at my college." (History and Environmental Studies Professor, 2017) Beginning in prehistory and concluding in the present, American Environmental History explores the ways the environment has affected the choices that became our history, and how our choices have affected the environment. The dynamic relationship between people and the world around them is missing from mainstream history. Putting the environment back into history helps us make sense of the past and the present, which will help guide us toward a better future.

The good practice guidelines - which form the basis of an interactive policymaker's tool kit included on a CD accompanying the book - relate not only to the more focused problem of encouraging increased fertilizer use by farmers, but also to the broader challenge of creating the type of enabling environment that is needed to support the emergence of efficient, dynamic and commercially viable fertilizer marketing systems."--Jacket.
