This chapter examines the interactions between food production and land use in the context of how a global population can be fed to deliver food security. Increased crop production over the last 70 years has resulted from expansion of cropland and intensification. It is widely recognized that only a small proportion of future increases in crop production will come from new land cultivation (about 20%); the majority will come from intensification via increased yield (67%) and higher cropping intensity (12%). Because the area of cropped land is likely to increase proportionately less than the future demand for food, reducing the gap between current and potential yields is a major goal. Urbanization affects the use of land to produce food, but it also moves nutrients from rural to urban areas. Distinct and disparate views of urban communities have emerged in the value of food associated with a decrease in the ratio of food producers to food consumers. Changing land use is only one of a number of global environmental changes affecting food production and systems. To cope with climate and other global changes, incremental adaptations are possible but transformational adaptation will be required in some regions.
