摘要: A key element in making our food systems more efficient is the reduction of losses across entire value chain. Nevertheless, are often neglected. This paper quantifies Switzerland at various stages chain (agricultural production, postharvest handling and trade, processing, service industry, retail, households), identifies hotspots analyses reasons for losses. Twenty-two categories modelled separately a mass energy flow analysis, based on data from 31 companies within chain, public institutions, associations, literature. The balance shows that 48% total calories produced (edible crop yields harvest time animal products, including slaughter waste) lost whole Half these would be avoidable given appropriate mitigation measures. Most occur household, agricultural production stage Households responsible almost half (in terms calorific content).
