Gross self-sufficiency rate of 59%
Since the early 20th century, Switzerland’s resident population has grown by a factor of 2.6 to over 8.5 million (2018). At the same time, breeding and technical progress in agriculture has seen food production increase. This has meant that 60% of food consumption (in terms of usable energy) has been covered by domestic production over the past 20 years. In 2017 the gross self-sufficiency rate was 59%. With regard to livestock products, domestic production also depends on imported fodder. Net self-sufficiency (2017: 52%) includes only food produced with domestic fodder.
