Peri-urban agriculture and Cultural heritage. The public potential of the in-between areas.

The development of agricultural entrepreneurship, in the farming areas near the cities, is limited and conditioned by the consequence of the urbanization phenomenon with his infrastructure grid, the unlawful buildings, the uncertainly contract and the problems caused by the wrong prevision of the urban development. To the other side, the proximity at the city and so at the urban zone, could represent a potential opportunity to grow and develop for the bordering areas, for example supplying secured and controlled food product and the guarantee of the ambient safety. The connection between the city and the farmland could represent an opportunity to improve the welfare of the whole area near the city, that is possible with a close relationship between the development of the sustainable agriculture and the city. This renewed interest in the agricultural production depends not only by urban reason or economics interest, but by a new conception of city that can improve the use of agricultural gardening to overcompensate the empty spaces between the industrial and the rural areas, that peri-urban spaces which are including between buildings and cartographic empty. The paper will illustrate that the cohabitation of agricultural and the city is possible, analyzing the case of the American Rust Belt, the northeast large area in the united states characterized by the presence of an old and dismissed iron industry surrounded by an extended space of farm field. In the lasts years American policy, that is rather unknown by the European academic literature, promotes to standardise interventions for the process documentation of all the cultural heritage buildings of Detroit, Cleveland and Cincinnati and the agricultural development of the nearest areas; in this paper will evaluate the different approaches and the economic consequences for the Rust Belt controlled decrease, with the aim to formulate a theoretical model, which is applicable in different urban landscapes and multiple social contexts of the global city. This dissertation will look for a theoretical approach for an universal peri-urban agriculture to realized on the future, a new image of the city that, as Richard Ingersoll said, could be attended as a home garden.
