Urbanization effects on vegetation and the alteration in land use is likely to be the major driver of fragmentation and the loss of ecosystem services (ESS) and biodiversity. Understanding varying levels of biodiversity within cities is pivotal to protect ESS. However, due to the high complexity of urban systems, ecological connectivity assessment in urban planning remains challenging. This article evaluates policy documents and tools for ESS assessment in Stockholm, Sweden. Stockholm is an interesting city for studying ESS planning and management since Sweden has a long tradition of formal policy for biodiversity management. An overview is presented of tools and approaches to measure ESS at different scale levels used in the urban planning process in Stockholm. Their application illustrates the complementary nature of these tools, but also the need to integrate them in a platform based on a GIS (Geographic Information System) model. Ultimately, the development of such an integrated tool should inform and support planning practice in guiding urban systems towards greater sustainability.

The planning process is a multiactor, multilevel process, and the techniques we need for it must be suitable for all the protagonists involved. Moreover, the difficulty in dealing with the complexity of urban systems and the related difficulty of analyzing and forecasting are twofold: one kind of difficulty lies in the complexity of the system itself, and the other is due to the actions of actors, which are "acts of freedom." Correspondingly, the process of urban planning requires a set of techniques and models that have proved to be of great potential for management of communication, participation, consensus-building and system' simulation. In this paper, we describe the peculiarity of the articulated set of tools that should be used to support planning, allowing the setting up and management of processes of participation and communication tailored to the needs of specific projects — a set of friendly tools that make the relationship between technicians, clients and users effective and efficacious. Following this discussion we present a very flexible software environment based on cellular automata (Cellular Automata General Environment — CAGE) that can be used to simulate planning decisions and can be coupled with other modules dealing with the "social side" of complexity.

Planning Processes

Energetic resilience is seen as one of the most prominent fields of investigation in the upcoming years. The increasing efficiency of urban systems depends on the conversion of energetic production of buildings, and therefore, from the capacity of urban systems to be more rational in the use of renewable resources. Nevertheless, the integration of the energetic regulation into the ordinary urban planning documents is far from being reached in most of planning processes. In Italy, mainstreaming energetic resilience in ordinary land use planning appears particularly challenging, even in those Local Administrations that tried to implement the national legislation into Local Building Regulation. In this work, an empirical methodology to provide an overall assessment of the solar production capacity has been applied to selected indicators of urban morphology among the different land use parcel-zones, while implementing a geographic information system-based approach to the city of Moncalieri, Turin (Italy). Results demonstrate that, without exception, the current minimum energy levels required by law are generally much lower than the effective potential solar energy production that each land use parcel-zone could effectively produce. We concluded that local planning processes should update their land use plans to reach environmental sustainability targets, while at the same time the energetic resilience should be mainstreamed in urban planning by an in-depth analysis of the effective morphological constraints. These aspects may also represent a contribution to the international debates on energetic resilience and on the progressive inclusion of energy subjects in the land use planning process.

Design Competition

Interest is growing in designing resilient and ecologically rich urban environments that provide social and ecological benefits. Regenerative and biocentric designs fostering urban ecological habitats including food webs that provide ecosystem services for people and wildlife increasingly are being sought. However, the intentional design of urban landscapes for food webs remains in an early stage with few precedents and many challenges. In this paper, we explore the potential to design (for) urban food webs through collaborations between designers and ecologists. We start by examining the ecology and management of Jamaica Bay in New York City as a case study of an anthropogenic landscape where ecosystems are degraded and the integrity of extant food webs are intertwined with human agency. A subsequent design competition focusing on ecological design and management of this large-scale landscape for animal habitat and ecosystem services for people illustrates how designers approach this anthropogenic landscape. This case study reveals that both designing urban landscapes for food webs and directly designing and manipulating urban food webs are complicated and challenging to achieve and maintain, but they have the potential to increase ecological health of, and enhance ecosystem services in, urban environments. We identify opportunities to capitalize on species interactions across trophic structures and to introduce managed niches in biologically engineered urban systems. The design competition reveals an opportunity to approach urban landscapes and ecological systems creatively through a proactive design process that includes a carefully crafted collaborative approach to constructing ecologically functioning landscapes that can integrate societal demands. As designers increasingly seek to build, adapt, and manage urban environments effectively, it will be critical to resolve the contradictions and challenges associated with human needs, ecosystem dynamics, and interacting assemblages of species. Ecologists and designers are still discovering and experimenting with designing (for) urban food webs and fostering species interactions within them. We recommend generating prototypes of urban food webs through a learning-by-doing approach in urban development projects. Design and implementation of urban food webs also can lead to research opportunities involving monitoring and experiments that identify and solve challenges of food-web construction while supporting and encouraging ongoing management.

Unexpected Consequences

Purpose The purpose of this paper is to study the unexpected consequences in the operation of urban environments. Prediction within the urban planning process often presents difficulties and unintended consequences. It is not enough to develop a good project. Unexpected consequences are possible because of the environment. The authors argue that these problems of uncertainty can be minimized with citizen participation and the use of new technologies. Design/methodology/approach The problem of how urban planning initiatives result in unexpected consequences is described. These effects are determined by studying a series of cities and real urban environments. A case study on urban accessibility is developed for a better understanding of the problem. Findings Avoiding unexpected consequences in the operation of urban environments is strongly linked to the concept of Smart City 3.0. This concept is based on the co-creation. In this line to address the problem, a citizen-centric methodology using the latest information and communications technologies and internet of things technologies is presented. As a practical application, different categories of unexpected events related to the Faculty of Education building at the University of Alicante have been identified as a consequence of the impact of its environment. An uncomfortable or non-accessible environment causes unforeseen behaviour of individuals. Originality/value There are no analytical tools to investigate how aspects of the urban environment cause uncertainty about the acceptance of projects by future citizen users. This work takes a step forward in that direction.

Land Use Development

The land and town planning legislation concerning the planning of land use development within the united territorial communities (UTC) is considered. It is found that legislative norms need to be finalized. The necessity of updating the existing land management documentation developed prior to the adoption of the Law of Ukraine "On Land Management" and changes in the structure of urban development in connection with the adoption of the Law of Ukraine "On Regulation of Urban Development" was proved as they do not ensure the integrity of the planning process within the territories of these communities through their institutional incapacity (proved by the example of the Palan Unified Territorial Community of the Uman district of the Cherkasy region). The priority of land management and urban planning documents as the most influential tools in planning the development of land use systems in UTC is scientifically grounded and their interdependence established.

The Relationship

The expansion of urban agglomerates is causing significant environmental changes, while the demand and need for sustainability keep on growing. In this context, urban and peri-urban agriculture can play a crucial role, mainly if associated with an agroecological approach. Indeed, the extensive use of living fences and tree rows can improve the environmental quality, assuring ecosystem services (ES), developing a sustainable urban food system and increasing local productions and the related socio-economic improvements. This study aims to assess the benefits of an agroecological requalification of a dismissed peri-urban area in the South Milan Agricultural Regional Park (Italy), by evaluating two possible scenarios, both involving planting trees and shrubs in that area. The software I-Tree Eco simulates the ecosystem services provision of planting new hedgerows, evaluating the benefits over 30 years. The study underlines the difference between the two scenarios and how the planted area becomes an essential supplier of regulating ecosystem services for the neighbourhoods, increasing carbon storage and air pollution removal. Results were then analysed with a treemap, to better investigate and understand the relationship between the different ecosystem services, showing a notable increase in carbon sequestration at the end of the simulation (at year 30). The study shows a replicable example of a methodology and techniques that can be used to assess the ES in urban and peri-urban environments.

Key Barrier

Redesigning and retrofitting cities so they become complex systems that create ecological and cultural–societal health through the provision of ecosystem services is of critical importance. Although a handful of methodologies and frameworks for considering how to design urban environments so that they provide ecosystem services have been proposed, their use is not widespread. A key barrier to their development has been identified as a lack of ecological knowledge about relationships between ecosystem services, which is then translated into the field of spatial design. In response, this paper examines recently published data concerning synergetic and conflicting relationships between ecosystem services from the field of ecology and then synthesises, translates, and illustrates this information for an architectural and urban design context. The intention of the diagrams created in this research is to enable designers and policy makers to make better decisions about how to effectively increase the provision of various ecosystem services in urban areas without causing unanticipated degradation in others. The results indicate that although targets of ecosystem services can be both spatially and metrically quantifiable while working across different scales, their effectiveness can be increased if relationships between them are considered during design phases of project development.

Urban systems are characterized by complexity and dynamicity. Data-driven simulations represent a promising approach in understanding and predicting complex dynamic processes in the presence of shifting demands of urban systems. Yet, today’s silo-based, de-coupled simulation engines fail to provide an end-to-end view of the complex urban system, preventing informed decision-making. In this article, we present DataStorm to support integration of existing simulation, analysis and visualization components into integrated workflows. DataStorm provides a flow engine, DataStorm-FE , for coordinating data and decision flows among multiple actors (each representing a model, analytic operation, or a decision criterion) and enables ensemble planning and optimization across cloud resources. DataStorm provides native support for simulation ensemble creation through parameter space sampling to decide which simulations to run, as well as distributed instantiation and parallel execution of simulation instances on cluster resources. Recognizing that simulation ensembles are inherently sparse relative to the potential parameter space, we also present a density-boosting partition-stitch sampling scheme to increase the effective density of the simulation ensemble through a sub-space partitioning scheme, complemented with an efficient stitching mechanism that leverages partial and imperfect knowledge from partial dynamical systems to effectively obtain a global view of the complex urban process being simulated.
