This volume compiles state-of-the-art scientific knowledge on the technologies that are used to quantify and reduce the environmental impact of livestock production in the cattle, pig and poultry industries. It makes a serious statement about how such technology can contribute to the sustainability of the livestock industry in the future. As the global livestock sector is growing, modern farm animal production is increasingly regarded as a source of solid, liquid, gaseous and dust emissions, which can be both nuisance and environmentally harmful. In light of hardening regulations and social pressure, there is increasing interest in scientific research on air pollution and emissions from livestock operations. The present chapters focus on methodology improvement, harmonization of measurements, and modeling aspects. Key aspects, such as renewable energy sources, nutritional approaches to reduce enteric methane emissions, technical options for manure management, and the use of sensors, are covered. By sharing good practices, this book is a valuable reference for a diverse readership. Experts across the veterinary and animal sciences, agricultural engineering, the food industry and sustainability research will benefit from the findings.

The agricultural world has changed significantly during the last years. The excessive use of heavy machinery, waste disposal, the use of agrochemicals and new soil cultivation means led to severe problems, which agricultural engineers have to cope with in order to prevent soil from permanent irreversible damage.

This Soil Biology volume will update readers on several cutting-edge aspects of sustainable soil engineering including topics such as: soil compaction, soil density increases, soil disturbance and soil fragmentation; soil tillage machineries and optimization of tillage tools; soil traffic and traction, effects of heavy agricultural machines, the use of robotics in agriculture and controlled traffic farming; mechanical weed control, the characterization of soil variability and the recycling of compost and biosolids in agricultural soils.

With the agricultural sector pledging to improve its sustainability, there is an urgent need to move away from linear food production models which rely on significant raw material inputs and generate large amounts of residual waste. Developing circular agricultural production systems reviews the emergence of circular agriculture as an approach to improving the sustainability of the agricultural sector. The book addresses recent advances in understanding and developing closed-loop systems to optimise crop nutrient cycles and resource use, as well as ways agricultural wastes can be recycled back into agricultural production or used as feedstock to produce a range of bio-based materials. With its comprehensive coverage, the book showcases how to develop circular agricultural production systems, from using crop residues as livestock feed and developing new bio-based fertilizers, to producing biogas from livestock manure and manufacturing bio-plastics from agricultural waste.
