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.
“Current agriculture wastes both agricultural inputs and outputs, leading to lower system productivity, higher costs and environmental pollution. A drive toward circular agricultural production systems is necessary to ensure nutrition security and to meet our goals of tackling climate change, biodiversity loss and environmental pollution. This volume, edited by Professor Barbara Amon – a world-leading scientist in the field – features contributions from an array of expert authors and will be a must have item to anyone concerned with the challenge of developing circular agricultural production systems.” (Pete Smith, Professor of Soils & Global Change, University of Aberdeen, UK and Science Director of Scotland's ClimateXChange)
“The proposed book on circular agricultural systems will be an important contribution to the development of a sustainable bioeconomy. The book includes an ideal strategy for achieving this development, focussing on optimising inputs, reusing residues and developing co-products.” (Tom Curran, Associate Professor and Vice Principal for Internationalisation in the College of Engineering & Architecture, University College Dublin, Ireland)
