In recent decades, there has been growing interest among farming and scientific communities toward integrated crop– range–livestock farming because of evidence of increased crop production, soil health, environmental services and resilience to increased climatic variability. This paper reviews studies on existing cropping systems and integrated crop– range–livestock systems across the USA which...

The evolutionary processes that have enabled Bos taurus cattle to establish around the globe are at the core to the future success of livestock production. Our study focuses on the history of cattle domestication including the last 60 years of B. taurus breeding programmes in both favourable and unfavourable environments and its consequences on evolution and fitness of cattle. We discuss the em...

Coupled human and natural systems (CHANS) are systems of feedback linking people and ecosystems. A feature of CHANS is that this ecological feedback connects people across time and space. Failing to account for these dynamic links results in intertemporal and spatial externalities, reaping benefits in the present but imposing costs on future and distant people, such as occurs with overgrazing. ...

Interest in the welfare of cattle in the beef industry has intensified over time because of ethical concerns and varying societal perceptions that exist about the treatment and living conditions of farm animals. The definition of welfare will vary according to an individual's philosophies (how one defines and prioritizes what is "good"), experiences (societal and cultural influences of animal r...

Mountain livestock systems, and particularly those based on breeding small ruminants, traditionally constituted a mainstay element of the local economy in Southeastern Spain's mountainous areas. With the rural exodus, which began in the early sixties, these systems were in critical danger of disappearing, due to, among other causes, the scarcity of shepherds and goatherds, the breakdown of an e...

In this letter, we investigate the effects of crop yield and livestock feed efficiency scenarios on greenhouse gas (GHG) emissions from agriculture and land use change in developing countries. We analyze mitigation associated with different productivity pathways using the global partial equilibrium model GLOBIOM. Our results confirm that yield increase could mitigate some agriculture-related em...

Prescribed fires are used to manipulate and manage rangelands, but effective monitoring techniques are needed to ensure that management goals and objectives are being met. The application of an effective fire program on rangelands is not a simple task. Overgrazing by livestock since the early development of the livestock industry has altered the vegetative complex on most rangelands with an inc...

There is an increasing interest for sustainable forms of livestock production systems, which will provide a balanced relationship between environmental, socio-cultural and economic factors. The small ruminant sector is examined with particular focus on the possibilities of improving the sustainability of small ruminant systems and on the possible role of organic production to meet the demand of...

Degrading antibiotics discharged in the livestock manure in a well-controlled bioprocess contributes to a more sustainable and environment-friendly livestock breeding. Although most antibiotics remain stable during manure storage, anaerobic digestion can degrade and remove them to various extents depending on the concentration and class of antibiotic, bioreactor operating conditions, type of fe...

FAO has considered insects as food since 2003 [1] and is promoting consumption of insects (entomophagy) in the Western world because of the possibilities for sustainable production it offers. Insects as food are considered to leave smaller ecological footprints than conventional livestock (beef, pigs, and poultry) regarding feed, land and water needs, as well as greenhouse gas and ammonia emiss...
