INTRODUCTION Evaluation plays a key role in planning approaches aimed at fostering territorial resilience. Resilience is defined as the capacity of a territorial system to persist, adapt or transform in the face of pressure 2 . The resilience concept is therefore characterized by a strong evolutionary nature and it understands the world as complex and unpredictable (Davoudi, 2012). To operationalise resilience, a planning approach that includes and addresses the concept of “uncertainty” is thus urgently needed. Adaptive planning able to promote a “learn-by-doing approach” (Kato and Ahern, 2008; Gunderson, 1999; Holling, 1978) can respond appropriately to this challenge. The adaptive approach to planning – namely an approach able to accept and manage uncertainty (Light et al., 1995) – has been used for decades in the field of planning and management of natural resources (Mondini, 2016; Walters and Holling, 1990). On the contrary, its systematic application in spatial and landscape planning policies, although desirable in a resilience perspective, is not common (Ahern, 2011). This paper presents an experimentation that fully fits into this approach and puts evaluation at the heart of planning policies aimed at promoting territorial resilience. In particular, a set of indicators was designed and applied to assess and monitor the state of the landscape in the Autonomous Province of Trento. The Trentino landscape is currently subject to uncertain evolutionary dynamics due to the liberalization processes of the retail sector and therefore to the potential settlement of retail structures with a high landscape impact (see Section 2). In line with the holistic dimension of landscape, the set of indicators 1 The research here presented was developed within the framework of the activities implemented for the Autonomous Province of Trento (2011-2017) by the multi-disciplinary research group of the Interuniversity Department of Regional and Urban Studies and Planning (DIST), Politecnico di Torino, coordinated by Grazia Brunetta. The results of the research were also developed with the support of the Interdepartmental Responsible Risk Resilience Centre (R3C) of the Politecnico di Torino. 2 “Urban resilience refers to the ability of an urban system – and all its constituent socio-ecological and socio-technical networks across temporal and spatial scales – to maintain or rapidly return to desired functions in the face of a disturbance, to adapt to change, and to quickly transform systems that limit current or future adaptive capacity” (Meerow et al., 2016, p. 39). Urban resilience – namely the capacity of a territorial system to persist, adapt or transform in the face of pressure – calls for an adaptive approach to planning, able to face uncertainty and unpredictability. Evaluation plays a key role to support a "learn-by-doing approach", providing tools and methods able to sustain the definition of territorial and landscape policies under a resilience perspective. The present article illustrates an experimentation developed on a real-world case study in Trentino Region. In particular, the paper describes an integrated model aimed at providing an overall evaluation of the territory under examination, by means of multidimensional indicators and synthetic indexes useful to support planning and management processes.
