The progressive degradation of environment and urban sprawl inspired the search for alternative ways of urban development. In this context, the concept of a “regenerative city” has gained significant traction in the field. It encompasses a variety of principles and strategies to ensure that cities can function sustainably and do not just consume resources but also actively regenerate them. In this context, the role of urban farming is particularly relevant. Urban farming, as a multifunctional tool, can contribute to food security, ecological sustainability, community resilience, and social cohesion. By integrating nature into the very fabric of urban design and ensuring that cities can sustainably support their inhabitants, we move closer to a vision of cities that are not just places of residence but thriving ecosystems in their own right. To achieve this goal we need not invent urban theories de novo. Throughout the decades, researchers have proposed cities encompassing agrarian land. The present study aims to present three lesser-known theories of W. Czerny, L. Zimowski and O. Hansen on the backdrop of theories by i.e. L. Migge, F.L. Wright, particularly focusing on the role of agriculture within city framework and their implications for the built structure of cities in the future.
