Not sure whether organic farming techniques can feed everyone (may be possible), but there's a vast gulf between "completely organic" and "broadly toxic to the surrounding environment." Australia, Spain, the Netherands, and (increasingly) China have had a lot of success using physical exclusion with nets, greenhouses, and high-tunnels. They have their own unique problems (plastic waste, rainwater runoff), but these systems get incredible crop yields without significant synthetic pesticide or herbicide use. I really think highly automated, hydroponic, mostly non-vertical indoor farming is the future of vegetable agriculture, and represents huge potential added value (economic and otherwise) in the coming 100 years.
