In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.

21st Century Homestead: Urban Agriculture contains everything you need to stay up to date on urban agriculture

Water resources stored by dams and reservoirs play an essential role in water resource management, hydropower and flood control. Where there is an extensive network of dam infrastructures, dams have made a major contribution to economic and social development, providing considerable storage capacity per capita. However, dams and reservoirs may also have an important social and environmental impact, and should be studied within the framework of integrated water resource management and sustainable development. Dams and Reservoirs, Societies and Environment in the 21st Century presents the latest research on the role played by dams and reservoirs in 21st century societies, in developed, emergent and developing countries. It analyses the viability of dams and suggests alternative solutions from a holistic perspective, considering the technical, economic, social and environmental aspects. Other issues covered include the social acceptability of dams, public involvement and dam awareness. The book covers subjects ranging from dam engineering, through the benefits and drawbacks of dams, to their social and environmental impact, and contains numerous case studies of the constructive contributions that reservoirs have made to water development and management. The book is a valuable resource for professional and dam engineers, water managers, governmental organizations and commercial enterprises responsible for dam development and management.

Awarded honourable mention for the 2024 GFASG Book Award. How do we achieve food security for a global population now over 7 billion people and trending towards 10 billion by 2050? This study of the global dairy industry examines how to balance our needs with those of animals and the environment. It scrutinises ruminant bovines' worrying exhaling of methane, a greenhouse gas which, fortunately, evidence shows can be reduced by adding seaweed to cattle feed. Are the multi-thousand-cow mega-dairies of the USA appropriate models for Africa and Asia's high-growth dairy regions, where so many women are smallholders? Is it ethical to keep cows in confined animal feeding operations (CAFOs), eating unnatural high-energy/low fibre diets when they prefer grazing pasture? Other issues include hormones for oestrus stimulation, and GMOs for milk yield, stressing cows' immune systems and drastically shortening longevity. This book offers multifaceted discussion of the central and ancillary issues relevant to dairying, and consumption of plant- and laboratory-based foods in the 21st century. No book to date offers such a comprehensive overview, linking ethics, environment, health and policy-making with in-depth coverage of the major dairy farming regions of the world.
