Since before the first industrial revolution, sociologists, historians, and urban planners have been addressing the relationship between the city and the countryside, but this debate has become more pressing nowadays with the spread of megacities, typically with a population of more than 10 million people. With more and more people living in urban areas, it is imperative to think of solutions for food production within cities, thereby making cities more independent from rural areas, which have historically been responsible for the supply of food to the entire planet.
The idea that cities will become self-sufficient in food production in the near future is both unrealistic and naive. Nevertheless, small initiatives such as urban gardens, either at home or public gardens run by the community, might be a good starting point for a much bigger change in the future. Or perhaps they simply represent a desire to return to one's roots and achieve a slightly slower lifestyle.
