Frontiers of Mechanical Engineering 2014, Volume 9, Issue 3,   Pages 203-217 doi: 10.1007/s11465-014-0308-8

Abstract:

This study proposes an eco-innovative design process taking into consideration quality and environmentalThis approach provides a synergy between the Life Cycle Assessment (LCA), the non-quality matrix, theIn the sequence of these tools, LCA assesses the environmental impacts generated by the system.Then, for a better consideration of environmental aspects, a new tool is developed, the non-quality matrix, which defines the problem to be solved first from an environmental point of view.

Can crop science really help us to produce more better-quality food while reducing the world-wide environmental

William J. DAVIES, Susan E. WARD, Alan WILSON

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 1,   Pages 28-44 doi: 10.15302/J-FASE-2019299

Abstract:

This paper reviews recent developments in crop science that can be the basis of a revolution in the global food system but it is also emphasized that such a revolution requires more than changes in food production and supply. We must more effectively feed a growing global population with a healthy diet while also defining and delivering the kinds of sustainable food systems that will minimise damage to our planet. There are exciting new developments in crop production biology but much existing crop science can be exploited to increase yields with the aid of a knowledge exchange (KE) framework requiring the use of new technology now available to most people across the globe. We discuss novel approaches at both the plant and the crop level that will enhance nutrient and water productivity and we also outline ways in which energy use and greenhouse gas (GHG) emissions can be reduced and labor shortages combatted. Exploitation of new biology and new engineering opportunities will require development of public-private partnerships and collaborations across the disciplines to allow us to move effectively from discovery science to practical application. It is also important that consumers contribute to the debate over proposed changes to food and farming and so effective KE mechanisms are required between all relevant communities.
