Achieving net zero dairy farming

To meet the targets outlined in the 2015 Paris Agreement, many countries are actively working towards reaching climate neutrality and achieving net zero by 2050. With the livestock sector estimated to contribute approximately 11-17% of global greenhouse gas emissions, more research and innovation is required to understand the cause of these emissions and how they can be reduced. Achieving net zero dairy farming provides a detailed insight into the fundamental processes within the dairy cow and those that occur on dairy farms that contribute to and reduce greenhouse gas emissions. The book also considers the range of strategies which can be implemented to support the transition to net zero, including improving housing and housing management, supplementing diets with methane-inhibiting feed additives and optimising manure/slurry application. Edited by a established name in the field, the book will be a standard reference for university and other researchers in dairy science, environmental scientists, dairy farmers and livestock advisors, as well as government and other agencies supporting the transition to net zero in agriculture. Dr John Webster is Emeritus Professor in Animal Husbandry at the University of Bristol, UK. He established the Animal Welfare and Behaviour Group at the University of Bristol, one of the largest and most highly-regarded of its kind in the world, and was a founder member of the Farm Animal Welfare Council which pioneered the Five Freedoms for farm animals. Professor Webster is editor of an earlier Burleigh Dodds Science Publishing volume: Achieving sustainable production of milk Volume 3: Dairy herd management and welfare (published in 2017). Other key books written or edited by Professor Webster include Understanding the Dairy Cow and Animal Husbandry Regained: the place of farm animals in sustainable agriculture.

Animal Husbandry Regained

The farming of animals for meat and milk confronts a stark dilemma. While world demand from a growing and more affluent human population is increasing rapidly, there are strong counter-arguments that we should eat less meat and pay more attention to environmental protection, animal welfare and human health and well-being. The aim of this book is to identify and explain the causes and contributors to current problems in animal husbandry, especially those related to 'factory farming', and advance arguments that may contribute to its successful re-orientation. Husbandry is considered in its broadest sense, namely the productive and sustainable use of the land for the good of all (plants, humans and other animals). The first part of the book outlines principles and arguments necessary to engage with current problems: depletion of natural resources and destruction of environment, animal welfare, food and health, fair trade and sharing resources. These arguments are illustrated by examples and sufficient evidence to justify the argument without obscuring the message. The second part presents a series of constructive proposals for change and development in animal husbandry, both in the developed world and subsistence agriculture. These include more integrated crop and livestock farming systems, the ethics of animal welfare and environmental management, and the evolution of a new social contract whereby the rights of the people to a fair share of good, safe food and a green and pleasant land are matched by a shared responsibility to preserve these things.

Plant Parasitic Nematodes in Temperate Agriculture

Nematodes are major pests of a number of temperate crops and can cause significant economic losses to farmers. This book provides a comprehensive account of such parasites, with chapters focusing on nematode pests of the main crops of importance in agriculture, horticulture and forestry. Written by leading authorities from the USA, UK, Canada, France, Netherlands, Australia, Bolivia and New Zealand this book is a definitive reference work for plant pathologists in general, and nematologists in particular.
