Ecology, Capitalism and the New Agricultural Economy
Author: Gilles Allaire
Publisher: Routledge
ISBN: 1351210025
Category : Science
Languages : en
Pages : 317
Book Description
With increasing pressure on resources, the looming spectre of climate change and growing anxiety among eaters, ecology and food are at the heart of the political debates surrounding agriculture and diet. This unique contribution unravels agri-environmental issues at different spatial levels, from local to global, documenting the major shifts in agriculture from a long-term perspective. The book begins by exploring the changes in the industrialisation and socialisation of agriculture over time, through the lens of institutional economics including The French Regulation School and Conventions Theory. Building on Polanyi’s ‘Great Transformation’, the chapters in this volume analyse long-term and contemporary changes in agriculture and food systems that have occurred throughout the last few centuries. Key chapters focus on the historical changes in provisioning and the social relations of production, consumption, and regulation of food in different socio-political contexts. The future of agriculture is addressed through an analysis of controversial contemporary political claims and their engagement with strategies that aim to improve the sustainability of agriculture and food consumption. To shed light on ongoing changes and the future of food, this book asks important environmental and social questions and analyses how industrial agriculture has played out in various contexts. It is recommended supplementary reading for postgraduates and researchers in agricultural studies, food studies, food policy, the agri-food political economy and political and economic geography.

Breeding for Robustness in Cattle
Author: Marija Klopčič
Publisher: Brill Wageningen Academic
ISBN: 9789086860845
Category : Cattle
Languages : en
Pages : 0
Book Description
The past decade has revealed unfavourable trends in e.g. fertility, udder health and locomotion in some major dairy cattle breeds due to a large increase in production and insufficient consideration of functional traits in the breeding goals. Such unfavourable trends in some functional traits increase costs. Additionally, the enlargement of herds leads to less available labour time per individual cow. This asks for cows that are easy to handle. At the same time, society is demanding a higher welfare standard of animals. These contradicting developments have increased the desire for so called more robust animals. Robustness can be defined as 'the ability to maintain homeostasis in commonly accepted and sustainable herds of the near future'; or 'the ability of the cow to function well in the environment she lives in as well as in a wide range of climates and production systems'. This book contains a series of articles (26) dealing with the concept of robustness, including aspects like evolution, genetics, environment, animal health and welfare, and integrity. Besides the major functional traits also the links to energy balance, hot climatic conditions, and the attitude and input of stakeholders towards robustness as part of the breeding program are discussed. This book is the first attempt to summarise the available knowledge concerning this topic in cattle, making this book unique. The contributions are from authors of 16 countries from all over the world. However, the focus is presently on farm animal level, while in future robustness of the whole production system may also require additional attention.

A Crossbreeding Experiment with Dairy Cattle
Author: Milton Henry Fohrman
Publisher:
ISBN:
Category : Agriculture
Languages : en
Pages : 132
Book Description
In 1939, when the Bureau of Dairy Industry began its crossbreeding experiment at Beltsville, the published information on the crossbreeding of dairy cattle was slight, unimpressive, and very little of it was based on experimental results. The crossbreeding investigations at Beltsville were undertaken to develop knowledge on the subject which would provide a sound basis for advising the operators of milk-producing farms what to expect if they used crossbreeding in hopes of producing better replacements for their milking herds. Final results on any dairy cattle breeding research project cannot be published until the last animal on the project has died, so this report covers the breeding performance and milk and butterfat production on all individuals used on the project which have had time to complete a normal first-lactation period.
