Expect three patterns to manifest, based on climate, geography, and culture. First, large-scale, export-driven monoculture will give way to small-scale, local-driven polyculture. That will (hopefully) help serve the caloric and nutritional needs of local communities, but it will come at the cost of economies of scale. Whether you look at it from the point of view of inputs or reach or tech or capital or planting preferences, the volume of foods produced on Earth in aggregate must decline.
