摘要

Avoiding food loss and waste may counteract the increasing food demand and reduce greenhouse gas (GHG) emissions from the agricultural sector. This is crucial because of limited options available to increase food production. In the year 2010, food availability was 2096 higher than was required on a global scale. Thus, a more sustainable food production and adjusted consumption would have positive environmental effects. This study provides a systematic approach to estimate consumer level food waste on a country scale and globally, based on food availability and requirements. The food requirement estimation considers demographic development, body weights, and physical activity levels. Surplus between food availability and requirements of a given country is considered as food waste. The global food requirement changed from 2,300 kcal/cap/day to 2/400 kcal/cap/day during the last 50 years, while food surplus grew from 310 kcal/cap/day to S10 kcal/cap/day. Similarly, GHG emissions related to the food surplus increased from 130 Mt CO_(2eq)/yr to 530 Mt CO_(2eq)/yr, an increase of more than 30096. Moreover, the global food surplus may increase up to 850 kcal/cap/day, while the total food requirement will increase only by 296-20% by 2050. Consequently, GHG emissions associated with the food waste may also increase tremendously to 1.9-2.5 Gt CO_(2eq)/yr.
