Abstract
Sustainable food production covers a wide range of perspectives and embraces issues relating to environment, economy and society. Sustainability of food production systems faces challenges ranging from environmental degradation, resource competition to elevated food demands and integration of agriculture into the global economy. Considering its far-reaching socio-economic implications, this review first provides an overview of key characteristics that distinguish sustainable food production from the conventional agricultural practices. In addition, technologies in promoting sustainable food production are summarized. Among those modern techniques, urban agriculture, next-generation plant-based foods and food nanotechnology are discussed in detail. Finally, futuristic solutions and research work are proposed in this review to provide guidance for designing sustainable Agri-Food system.
