    • SS - Urban planning and innovation potentially induced by the SEAChair: Mariolina BesioEnvironmental knowledge and normative potentiality of environmentalcomponents.A case study: the SEA of Genoa land use planGiampiero LombardiniDSA – Università di Genova Cagliari, 11 maggio 2012
    • Urban planning: a definition We can define the sum of matters that contribute to the transformation of the physical environment of the city as "territorial production system Urban planning can be defined as the set of governance practices (in their economic, legal and technical dimensions) that through the allocation of land use (zoning), interacts and tries to regulation of the system of territorial production The main function of the urban plan at (local) municipal level is therefore the control of territorial transformations through the formal allocation of land uses, where different rules regarding the potential construction and implementation of infrastructure and services.
    • Relationships between urban plan andenvironment • The environmental assessment of the outcomes of this process of government regulation therefore must consider the technical and operational characteristics by which an urban plan performs its function: • in this case they have an irreducible spatial dimension. • The planning regulation is done by organizing urban space with • grids (which may have economic-operational nature: Mazza, 2007; • symbolic rule: Rykwert, 2002; • morphological design: Piroddi, 2000) • The construction of the potential rules through which the planners should (or rather, would like) organize the future city still needs a process of elaboration and structuring of spatial knowledges, under which are then performed the choices of the plan regarding the admissible transformations.

    • Environmental contexts The environmental contexts are urban regions with a distinctive uniform, under which it is possible to distinguish the structural aspects of the different parts of the territory. Each urban region are actually different territorial morphology, forms of land use and settlement areas, with a specific and recognizable geographic landscapes characterized by specific problems with regard to natural resources and human settlements and the themes of regeneration and sustainable development.

    • Conclusions The construction of a single logical system of descriptive environmental data allowed us to achieve some results. The first was that of reducing the complexity resulting from very large databases. The second was to be checked at each step the set of relationships that bind each other but interrelated phenomena so difficult to be synthesized. It also permitted to make comparable data on the state of the environment (and its potential for changes) with data derived from the choices of the town plan. Finally, he allowed the plan to organize knowledge in a way that would be represented spatially (key issue since the evaluation must be anchored on time to the geographical space).
