Integrating Green-Infrastructures Design in Strategic Spatial Planning with Geodesign

Abstract

In the last decades green infrastructure planning, design, and management have been widely recognized as a way to contribute to reach higher levels of sustainability of development. However, often green infrastructures are considered in a sectoral way, while their design should be more integrated within comprehensive planning and design. The paper proposes the use of geodesign methods and technology to support the early phases of integrated strategic territorial planning, in order to enrich the relationships between the design of green infrastructure and of the other relevant systems via more comprehensive planning and design, and by applying systems thinking. A case study developed with architecture and engineering students under the umbrella of the International Geodesign Collaboration is used, to demonstrate how with intensive geodesign workshops it is possible to create spatially explicit design scenarios which take into account the relationships between green infrastructure and other territorial systems and dynamics. A set of analyses on the case study results of the two scales is used to demonstrate the assumption. It is also argued that geodesign intensive workshops can, in a very short time, contribute to raising the awareness among the participants of collaborative design to the importance of green infrastructure in strategic territorial planning.Sustainability 2020, 12, 1820 2 of 22 movement [4]. Connectivity and multi-functionality are considered key characteristics for the GI to remain resilient to change [1,5]. The first characteristic is related to the need of biotic functional groups to have not only high-quality living and restoration space (i.e., core areas), but also to be able to move across patches in order to support genetic diversity [6]. The second characteristic concerns the ability of a GI to perform several functions in the same spatial area related to the provision of a variety of Ecosystem Services (ESs), serving a range of functions for both nature and society.Due to its multi-sectorial nature, GI requires a holistic and cross-sectorial approach to spatial planning in order to both stimulating possible synergies and coordinating initiatives, and to avoid the consequent risk of conflicts between objectives related to different goals [1]. recognize the central role of GI in guiding the early stage of the planning process across the different levels (i.e., regional, municipal and project scale) and proposed a reform of the legal framework of landscape and urban planning at the Autonomous Region of Valencia by identifying a unique GI as an ecological-based tool to overcome fragmentation and to interconnect all the different policies concerning landscape protection. Over the last decades a wide range of GI projects have been carried out on local, regional, national and trans-boundary levels, highlighting the necessity for projects defined in different scales to be closely interconnected and coordinated in order to maximize the GI benefits.Green infrastructure can be reinforced through str...

Green Infrastructure Planning Principles: Identification of Priorities Using Analytic Hierarchy Process

“…According to Wright [9], the concept of green infrastructure is used loosely by many actors, which results in vast and diverse interpretations depending on the sector and context in which the concept has been developed [4,15]. In addition, the geographical location and culture dynamics in which green infrastructure is being used also influences the different concepts found in the literature [7,13].…”

“…So, to face the intense environmental threats urban and rural areas are facing-mainly due to climate change-green infrastructure (GI) planning has become a priority for decision makers and practitioners around the world. However, due to its ambiguity, practitioners and decision makers still struggle to understand its true benefits and the best practices for its implementation and management at local level [4,5].…”

The Key Factors Driving the Development of New Towns by Mother Cities and Regions: Evidence from China

“…Through a new analytic framework based on the integration of geographic information systems (GIS) and an extended shift-share analysis, Sui models the Spatial Economic-Impacts of New Town Development in Hong-Kong [38]. Campagna and Steinitz creatively proposed Geodesign [39][40][41], and conducted an in-depth discussion on its application in the field of strategic planning and green infrastructure [42,43]. Tiboni and Rossetti further expanded the comprehensive application analysis method based on GIS and introduced it into the framework of public transportation planning and analysis, such as bus station planning [44,45].…”

Landscape Design toward Urban Resilience: Bridging Science and Physical Design Coupling Sociohydrological Modeling and Design Process

“…Steinitz suggests that Geodesign can be an effective instrument that creates design proposals and simulates design impacts with geospatial technologies [30]. The concept of Geodesign has recently been expanded in the literature with noted applications to a variety of cases [29,[31][32][33][34][35]. Dangermond [36] notes that geodesign encompasses multiple disciplines and professions through a common set of geospatial technologies and design processes.…”

“…To this aim, we need a more inclusive framework that brings resilience science and urban dynamics into creative physical and practical design. Previous studies have used Geodesign processes to link science and landscape design (see Gu et al [29], Wu [23], Opdam et al [45], and Campagna et al [35]), although there are still critical gaps in the connection.…”
