The issue related to the limits of cities emerges from the discussion about sustainability, which highlights the importance of rural and productive activities to support urban life, as well as the incomplete urbanization process that has taken place in the Brazilian cities. Based on these two aspects, the authors seek to trace the characteristics of the rural-urban landscape of the city of Passo Fundo (Brazil). They analyze the socio-economic and legal dynamics that influence the urban space and verify how these aspects influence the landscape and its changes over time.
