Abstract [en]

Depending on quantity and composition of food as well as on production conditions and techniques, the space needed to sustain an individual’s nourishment varies. The amount of space needed also depends on the use of resources such as energy, water, and fertilizers, as well as potential land degradation and water pollution. Our study focuses on the changing spatial imprint of an average inhabitant of an expanding Swedish city, Linköping, from 1870 to 2000 taking into account both shifts in consumption as well as agricultural productivity and practices. Despite the distinctly larger amount of animal food products, such as meat and fish, consumed in 2000, we calculate the area needed to sustain an individual’s annual food consumption could be less than one fourth of that needed in 1870. However, if the import of various globally produced foods is included in our calculations, the land needed to sustain the consumption of an inhabitant of Linköping in 2000 doubles. We also argue that an examination of this regional imprint can be used to explore and evaluate possibilities for regional development.

Abstract [en]

Human food consumption has changed from the late 19th century to the turn of the millennium, and so has the need for resources to sustain this consumption. For the city of Linköping, situated in southeastern Sweden, the environmental imprint of an average inhabitant’s food consumption is studied from the year 1870 to the year 2000. The average consumer is the driving factor in this study, since changes in food consumption have a direct influence on the environmental imprint. This thesis analyses the environmental imprint of human food consumption from a historical perspective, by applying two different methods. An analysis of the average Swedish food consumption creates the basis for a material flow analysis of nitrogen and phosphorus, as well as a study of the spatial imprint.

Emissions of nitrogen and phosphorus into the hydrosphere have decreased over this period for the system of food consumption and production for an average consumer, while the input via chemical fertilizer has increased significantly. The efficiency of this system could be increased if for instance more phosphorus in human excreta would be reused within the system instead of large deposition and losses into the hydrosphere. The spatial imprint of human food consumption shows, given the changing local preconditions, that less space would be needed for regional production of the consumed food. However, the share of today’s import and thus globally produced food doubles this spatial imprint.

The results of this study show not only a strong influence of the consumption of meat and other animal products on the environmental imprint, but also great potential in the regional production of food. In the context of an increasing urban population, and thus additional billions of people who will live at an increasing distance from the agricultural production land, concern for the direct effects of our human food consumption can be of decisive importance for future sustainable food supply.
