This crucial Handbook investigates an urgent area for policy-makers, academia and industries alike: the circular economy. International experts on the subject bring together the latest thinking on this critical global issue. Providing a comprehensive overview of the mechanisms and consequences of the circular economy, as well as its limitations, it raises important questions concerning how the world should proceed when non-renewable resources, such as fossil fuels and minerals, are being depleted and the environment is struggling to cope with the waste and emissions of unsustainable production and consumption systems. Contributors explore a broad range of themes, such as new sustainable production and consumption systems, new design requirements, recycling systems, new business models and the social impacts of the circular economy, while also consolidating the many ways in which the topic has been dealt with in research, business and policy-making. Shedding light on a concept that has become increasingly relevant during the last decade, the Handbook of the Circular Economy is essential reading for students, academics and policy-makers trying to make sense of the plethora of ways in which the term has been applied and interpreted.

This collection features five peer-reviewed literature reviews on life cycle assessment (LCA) of crops. The first chapter discusses the application of LCA to agricultural systems and highlights key issues associated with its implementation, including delimitation of systems boundaries, defining the functional unit, handling coproduction, and the choosing of impact assessment methods. The second chapter explores the concepts of LCA and the coffee value chain. The chapter discusses how carbon footprint performances can be used to upgrade coffee value chains. The third chapter assesses the environmental impact of oil palm production during cultivation and as a result of land use change for new plantations. The chapter describes the principles and modelling steps of LCA, as well as the challenges ahead regarding further development and application. The fourth chapter reviews the core principles of LCA methodology, the state of the art of LCA for fruits and associated key challenges. The first complete LCA case study for export mango is also discussed. The final chapter assesses the environmental impact of banana production and highlights the importance of LCA in influencing the adoption of practices that can reduce or offset the carbon footprint of the banana value chain.

A prerequisite to improving the sustainability of agriculture are reliable methods to identify and quantify types of environmental impact. This collection summarises current research on the use of life cycle assessment (LCA) and other modelling techniques to measure and improve the sustainability of agriculture. Part 1 looks at current best practice and key methodological challenges in life cycle assessment. Part 2 reviews ways of modelling particular types of impact, from nutrient and carbon cycles to freshwater balances, energy use, pesticide use and biodiversity. Part 3 reviews the environmental assessment and optimization of sectors such as crops, ruminant and other livestock production as well as by-products. Assessing the environmental impact of agriculture will be a standard reference for researchers in agricultural and environmental science concerned with understanding and mitigating the environmental impact of agriculture.
