Agriculture and Urbanization

I am trying here to capture the dynamics that are conventionally associated with urban development and get back once again, to this question of agriculture. Once you have cities, you also have the reverse of cities, you have countryside. You have rural areas and their relationship with urban areas, and the need to develop agricultural goods, which you trade with increasing industrial goods. Increasing agricultural productivity, reduces labour needs and opportunities in rural areas, pushing people towards the cities. There is this notion that in order to have progress and development in cities, you need people. If everybody is busy growing crops, growing food that exists, you can't also have people going into the city. You need to increase productivity in the countryside. You have to have one farmer producing enough food for more than one family. then you will have growth and productivity in the countryside, which will free people to move to the cities., in fact, in many ways, it will compel it. They will go to the cities and search for jobs and provide the labour force with the production of all kinds of things.
