One could argue that greenhouses could help decentralize the farming industry, thereby mitigating the problem you mention, but these greenhouses would need reliable energy and transport infrastructure. If a given country already has reliable energy and transport then they likely have no issue with food distribution either. Then again, countries may be more inclined to invest in local greenhouse infrastructure if it meant raising the expertise level of the country (which leads to more local jobs, better education, etc).
