"The examination of the food's foot-print is based on the analysis of the nitrogen's fluxes, an approach that is adapted from functional ecology and biogeochemical. The Study proceeds with the measurement of the food's foot-print over three temporal thresholds: 1786, 1896 and 2006, showing the differences in the total demand of cereals, animal products and fruit and vegetables, as well as the geography of procurement's basins. A section of the study is focused on the environmental tensions generated by the agri-food system, particularly on the unbalance of the nitrogen's natural cycle. Finally, 6 scenarios for 2030 are proposed. The conclusion is that a strong re-localization of agriculture, combined with organic agriculture, a re-equilibration between breeding and cereal's production and the decrease of animal proteins in the human diet, would permit a long term sustainable food production and also the access to drinkable water for Paris Metropol."
