"Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.

In this volume, we examine the challenges and opportunities created by global migration at the start of the 21st century. Our focus extends beyond economic impact to questions of international law, human rights, and social and political incorporation. We examine immigrant outcomes and policy questions at the global, national, and local levels. Our primary purpose is to connect ethical, legal, and social science scholarship from a variety of disciplines in order to raise questions and generate new insights regarding patterns of migration and the design of useful policy.While the book incorporates studies of the evolution of immigration law globally and over the very long term, as well as considerations of the magnitude and determinants of immigrant flows at the global level, it places particular emphasis on the growth of immigration to the United States in the 1990s and early 2000s and provides new insights on the complex relationships between federal and state politics and regulation, popular misconceptions about the economic and social impacts of immigration, and the status of 'undocumented' immigrants.
