This essay explores key features of the intensification of animal production in relation to animal welfare and animal ethics. It looks at some traditional ethical ideas about animal care in order to help explain why the intensification of animal production has become such a prominent social and ethical issue. It suggests that some of the standard claims made by critics of intensive animal production are seriously flawed, and proposes an alternative interpretation to account for some of the key developments in the intensification of animal production. Finally, it explores how this interpretation, if correct, leads us to a different set of actions to address animal welfare concerns in intensive production systems.

By 2050 the world's population is projected to grow by one-third, reaching between 9 and 10 billion. With globalization and expected growth in global affluence, a substantial increase in per capita meat, dairy, and fish consumption is also anticipated. The demand for calories from animal products will nearly double, highlighting the critical importance of the world's animal agriculture system. Meeting the nutritional needs of this population and its demand for animal products will require a significant investment of resources as well as policy changes that are supportive of agricultural production. Ensuring sustainable agricultural growth will be essential to addressing this global challenge to food security. Critical Role of Animal Science Research in Food Security and Sustainability identifies areas of research and development, technology, and resource needs for research in the field of animal agriculture, both nationally and internationally. This report assesses the global demand for products of animal origin in 2050 within the framework of ensuring global food security; evaluates how climate change and natural resource constraints may impact the ability to meet future global demand for animal products in sustainable production systems; and identifies factors that may impact the ability of the United States to meet demand for animal products, including the need for trained human capital, product safety and quality, and effective communication and adoption of new knowledge, information, and technologies. The agricultural sector worldwide faces numerous daunting challenges that will require innovations, new technologies, and new ways of approaching agriculture if the food, feed, and fiber needs of the global population are to be met. The recommendations of Critical Role of Animal Science Research in Food Security and Sustainability will inform a new roadmap for animal science research to meet the challenges of sustainable animal production in the 21st century.

First published in 1964, Ruth Harrison's book Animal Machines had a profound and lasting impact on world agriculture, public opinion and the quality of life of millions of farmed animals. Concerned with welfare standards at a time when animal production was increasing in scale and mechanization, Ruth Harrison set about investigating the situation in a fair and even-handed way. Reporting her findings in this book, Harrison alerted the public to the undeniable suffering of calves living in veal crates and birds in battery cages. Written at the beginning of the intensive farming movement, which promised progress but in reality worsened conditions for domesticated animals, Animal Machines provides a fascinating insight into the system we are living with today and must continue with as the global population increases. Harrison's work brought about legal reforms, a greater understanding of farm conditions for animals and increased public awareness. Animal Machines is reprinted here in its entirety, accompanied by new chapters by world-renowned experts in animal welfare discussing the legacy and impact of Animal Machines 50 years on.

The Ethics of Agricultural Intensification: An Interdisciplinary and International Conversation Paul B. Thompson and John Otieno Ouko* Global agriculture faces a number of challenges as the world approaches the second decade of the third millennium. Predictions unilaterally indicate dramatic increases in world population between 2010 and 2030, and a trend in developing countries toward greater consumption of animal products could multiply the need for prod- tion of basic grains even further. Although global food production in 2000 was estimated to be adequate for the existing population, hunger and malnutrition are persistent problems that have led decision makers to recognize that increasing food production in specific regions may be the most effective way to address food se- rity for impoverished peoples. At the same time, there will need to be policy adju- ments that improve poor people’s access to current food supplies without simultaneously undercutting the ability of local producers to obtain needed cash income. What is more, the uncertain effects of global climate change on agricultural ecosystems complicate planning for this process, while poorly understood processes of globa- zation create additional unknowns from the side of social systems. In short, despite surpluses in many parts of the developed world, finding ways to increase food p- duction on both selected regional and a total global basis remains a priority for many farmers, policy makers and agricultural researchers.

"The economic costs and benefits of farm animal production and sustainability versus improving climate change and animal welfare presents one of the most complex dilemmas in agriculture today. This book, by top global authors and experts, outlines the problem whilst making policy-relevant recommendations"--

Informed livestock sector policy development and priority setting is heavily dependent on a good understanding of livestock production systems. In a collaborative effort between the Food and Agriculture Organization and the International Livestock Research Institute, stock has been taken of where we have come from in agricultural systems classification and mapping; the current state of the art; and the directions in which research and data collection efforts need to take in the future. The book also addresses issues relating to the intensity and scale of production, moving from what is done to how it is done. The intensification of production is an area of particular importance, for it is in the intensive systems that changes are occurring most rapidly and where most information is needed on the implications that intensification of production may have for livelihoods, poverty alleviation, animal diseases, public health and environmental outcomes. A series of case studies is provided, linking livestock production systems to rural livelihoods and poverty and examples of the application of livestock production system maps are drawn from livestock production, now and in the future; livestock's impact on the global environment; animal and public health; and livestock and livelihoods. This book provides a formal reference to Version 5 of the global livestock production systems map, and to revised estimates of the numbers of rural poor livestock keepers, by country and livestock production system.
