Book Description
Awarded Bookauthority's "Best Aquaculture Books of all Time" A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.

Book Description
This book was written by undergraduate students at The Ohio State University (OSU) who were enrolled in the class Introduction to Environmental Science. The chapters describe some of Earth's major environmental challenges and discuss ways that humans are using cutting-edge science and engineering to provide sustainable solutions to these problems. Topics are as diverse as the students, who represent virtually every department, school and college at OSU. The environmental issue that is described in each chapter is particularly important to the author, who hopes that their story will serve as inspiration to protect Earth for all life.

Book Description
This book will not serve as the "encyclopedia of cover crop management," but it’s close. The benefits of a wide range of individual cover crops and blends/mixes for specific agronomic crop rotations and geographic locations are included. Descriptions, photographs, and illustrations show how cover crops look in the field, including plant height, leaf architecture, and rooting patterns. Long term benefits are described for soil health, soil structure, water quality, nutrient contributions, soil biodiversity, air quality and climate change. In addition to the "whys" of cover crop use, the book includes details on the "hows:" how to choose cover crops for specific applications and locations; how (and when) to plant; how to manage and maintain the cover for maximum benefit; and how and when to terminate. Planting options include: drilling/planting between rows of an agronomic crop at planting time, or when the crop is short (i.e. corn in early June); "aerial" seeding with an airplane or high-clearance machine shortly before the crop reaches maturity; and drilling/planting immediately after harvest of the agronomic crop. Selected cover crops (blends) can help with pest and disease management. Cover crops are an economic input with an expected return on investment, similar to pesticides and fertilizer. As part of a continuous no-till system, cover crops provide long-term biological, chemical and structural benefits. The resulting increase in soil organic matter means the agronomic crop yields benefit from better water infiltration and water holding capacity, greater availability of nitrogen and other nutrients, deeper rooting, and increased soil microbial activity in the root zone.

Book Description
Urban agriculture offers promising solutions to many different urban problems, such as blighted vacant lots, food insecurity, storm water runoff, and unemployment. These objectives connect to many cities' broader goal of "sustainability," but tensions among stakeholders have started to emerge in cities as urban agriculture is incorporated into the policymaking framework. Growing a Sustainable City? offers a critical analysis of the development of urban agriculture policies and their role in making post-industrial cities more sustainable. Christina Rosan and Hamil Pearsall's intriguing and illuminating case study of Philadelphia reveals how growing in the city has become a symbol of urban economic revitalization, sustainability, and - increasingly - gentrification. Their comprehensive research includes interviews with urban farmers, gardeners, and city officials, and reveals that the transition to "sustainability" is marked by a series of tensions along race, class, and generational lines. The book evaluates the role of urban agriculture in sustainability planning and policy by placing it within the context of a large city struggling to manage competing sustainability objectives. They highlight the challenges and opportunities of institutionalizing urban agriculture into formal city policy. Rosan and Pearsall tell the story of change and growing pains as a city attempts to reinvent itself as sustainable, livable, and economically competitive.

Book Description
A comprehensive book on basic processes of soil C dynamics and the underlying factors and causes which determine the technical and economic potential of soil C sequestration. The book provides information on the dynamics of both inorganic (lithogenic and pedogenic carbonates) and organic C (labile, intermediate and passive). It describes different types of agroecosystems, and lists questions at the end of each chapter to stimulate thinking and promote academic dialogue. Each chapter has a bibliography containing up-to-date references on the current research, and provides the state-of-the-knowledge while also identifying the knowledge gaps for future research. The critical need for restoring C stocks in world soils is discussed in terms of provisioning of essential ecosystem services (food security, carbon sequestration, water quality and renewability, and biodiversity). It is of interest to students, scientists, and policy makers.

Book Description
The questions of population growth and food supply have long been of central concern to economists. The World Food Economy seeks to examine the lessons of the past for wealthy nations, where agricultural output has steadily risen for decades, as well as for developing nations where the advances of the “Green Revolution” in the 1960s have introduced new problems in addition to solutions. This text assesses the challenge of satisfying food demand during the twenty-first century as consumers and producers in every part of the world—rich and poor alike—feel the effects of expanded global commodity trade, food aid, and national legislation in response to globalization. Examines increases in agricultural output and productivity in both the developed and developing worlds Analyzes the centrality of agricultural development to general economic progress and explores cases where governments attempt to foster economic expansion while neglecting food production Assesses the challenge of satisfying food demand during the twenty-first century, given the effects of globalization on international trade and national legislation.
