Building a sustainable food value chain

Current food systems are mostly unsustainable from an economic, social and environmental point of view, being responsible for about one third of global greenhouse gas (GHG) emissions, says the Food and Agriculture Organization (FAO).They are also highly vulnerable to the impacts of climate change, such as greater outbreaks of pests and diseases, food loss and supply chain damage caused by extreme weather events and related economic and social impacts.The world needs more resilient and robust food systems to achieve food security, a point underlined even more by the effects of the Covid-19 crisis."The need for a transformational change of food systems is undeniable. Policymakers can be the powerful and needed agents of that change, especially in developing countries," the FAO said n a recent report.A Push to End Germany's Status as 'Paradise for Patent Trolls'Leadership in the fear zoneNissan's Unlikely CEO Guides Car Maker in Post-Ghosn EraThrough economic incentives and policies such as subsidies, tax exemptions and the establishment of standards, they can promote market transformation and support a shift toward more sustainable food systems, the United Nations agency added.The FAO defines a sustainable food value chain as "the full range of farms and firms and their successive coordinated value-adding activities".
