5 Using a newly developed model approach and combining it with remote sensing, pop6 ulation, and climate data, first insights are provided into how local diets, urbanisation, 7 and climate change relates to local urban food self-sufficiency. In plain terms, by utilizing 8 the global peri-urban food production potential approximately 1bn urban residents (30% of 9 global urban population) can be locally nourished, whereby further urbanisation is by far the 10 largest pressure factor on peri-urban agriculture, followed by a change of diets, and climate 11 change. A simple global food transport model which optimizes transport and neglects dif12 ferences in local emission intensities indicates that CO2 emissions related to food transport 13 can be reduced by a factor of 10. 14
