This paper assesses the relationship between food consumption patterns and the use of agricultural land. First, it calculates the amount of land needed to produce singular foods, and second, it assesses land requirements of food consumption patterns. The paper observes large differences among requirements for specific foods. Especially livestock products, fats, and coffee have large land requirements. The consumption of specific foods can change rapidly over time, causing shifts in land requirements. A rise or fall of requirements, however, depends on the initial consumption pattern. Patterns based on animal foods shifting towards market foods containing more staples require less land. This dietary change direction was shown for Dene/Métis communities in Canada. Patterns based on staples shifting toward diets containing more livestock foods and beverages require more land. This change direction was observed in the Netherlands. Per capita land requirements differ among countries. In Europe, Portugal showed the smallest requirement (1814m2), Denmark the largest (2479m2). The Danish pressure was mainly caused by large consumption of beer, coffee, fats, pork, and butter. The trend toward food consumption associated with affluent life styles will bring with it a need for more land. This causes competition with other claims, such as infrastructural developments or ecological forms of agriculture.
本文评估了食物消费模式与农业用地使用之间的关系。首先,它计算生产单一食物所需的土地量,其次,它评估食物消费模式的土地需求。本文观察到特定食物的需求存在很大差异。特别是畜产品、脂肪和咖啡的土地需求很大。特定食物的消费会随时间迅速变化,导致土地需求发生变化。然而,需求的上升或下降取决于初始消费模式。基于动物性食物的模式转向包含更多主食的市场食物所需土地较少。加拿大的德内/梅蒂斯社区就呈现出这种饮食变化趋势。基于主食的模式转向包含更多畜产品食物和饮料的饮食则需要更多土地。荷兰就观察到了这种变化趋势。各国的人均土地需求有所不同。在欧洲,葡萄牙的需求最小(1814平方米),丹麦最大(2479平方米)。丹麦的压力主要是由于啤酒、咖啡、脂肪、猪肉和黄油的大量消费。与富裕生活方式相关的食物消费趋势将带来对更多土地的需求。这会引发与其他需求的竞争,比如基础设施建设或生态农业形式。
