Towards the Establishment of a Green Infrastructure in the Region of Montreal (Quebec,Canada)

Through the analysis of semi-structured interviews held with key actors involved in the planning of the Greater Montreal region, we seek to understand the conditions that could lead to the establishment of a green infrastructure for the city. This article first describes the region's environmental and political context and then analyzes the opportunities, constraints, advantages and disadvantages in the implementation of this type of project. We conclude that experts favor an approach leading to ecological connectivity, but they underline several obstacles that could hinder its implementation.     

What Future for Green Infrastructure Planning? Evaluating the Changing Environment for Green Infrastructure Planning Following the Revocation of Regional Planning Policy in England

ABSTRACT

The revocation of the regional tier of planning by the UK Coalition Government in 2010 removed the established framework of strategic planning in England. Using a case study of green infrastructure (GI), this paper examines whether revocation has negatively impacted the development of environmental, and specifically GI policies and practice. It questions if changing government policy narratives have hindered advocacy and subsequently the delivery of GI and the extent to which it has been able to position itself as a mainstream approach in planning. Using the development of the RSS in England, and the North-East and East of England sub-regional GI strategies (areas of significant policy development), as case studies, the paper presents an ex-ante evaluation prior to revocation of the evolution of GI policy at a regional scale, alongside an ex-post assessment (2011–2015) of its continued growth within sub-regional policies. The paper concludes that whilst RSSs provided a promotional forum, that revocation has not negatively impacted upon GI development, as its advocates have facilitated a supportive policy-implementation environment which has led to the development of more integrated approaches in planning praxis.     

Improving Participation in Green Infrastructure Planning

Green infrastructure is a strategic planning concept that is able to address environmental, social and even economic problems by supplying a variety of benefits for society. Especially in times of public financial crises and spatial transformation, it is important to ensure that those services are high quality to guarantee that they will provide the intended benefits by integrating stakeholders’ knowledge and experience into green infrastructure planning. Active stakeholder participation leads to legitimate and informed future planning that accounts for society’s needs. This paper investigates participation approaches of six green infrastructure investments in Belgium, the UK, Germany and the Netherlands. The major aim is to explore how and when participation should take place to optimize participation in green infrastructure planning. This is achieved by surveying the stakeholders involved and conducting stakeholder discussions to identify their views on the participation approaches employed and their integration into the planning process. We found that stakeholders were generally satisfied with how they were involved but desired a broader and more tailored mix of approaches. Furthermore, we found several Arnstein gaps, which lead us to conclude by suggesting recommendations that are helpful for successful participation in green infrastructure planning.     

LP/HC and LULUs: The Political Uses of Risk Analysis in Land-Use Planning1

This paper examines how LP/HC (low-probability/high-consequence) risk analysis is used in planning for locally unwanted land uses, or LULUs. LULUs are development projects that are predictably objectionable to many of their neighbors. Examples are nuclear power plants, hazardous waste facilities, refineries, and airports. The paper begins by elaborating the idea of LULUs, focussing on those whose planning typically requires or invokes some form of LP/HC risk analysis. It then discusses how land planning and planners actually use the LP/HC approach to deal with LULUs. It argues that in practice land-use planners and their associates employ a concept of risk different from that of economists, scientists, and engineers and more like that of political decision-makers and the public at large. It concludes with a political interpretation that offers some suggestions for productively reducing this divergence in the treatment of LULUs that pose LP/HC risks.     

Experiences of running negotiable and non-negotiable developer contributions side-by-side

In England, Since the 1970s, a system of negotiated project-specific agreements between local planning authorities and developers/landowners has evolved into the sole mechanism by which part of land value uplift ‘released’ by the grant of planning permission is captured by government. In 2010, in an attempt to simplify and speed up the planning process – negotiated planning agreements were regarded as time-consuming and a brake on development – the Community Infrastructure Levy (CIL) was introduced. Originally intended as a simple flat rate charge to replace site-specific planning agreements, CIL now sits alongside that mechanism so that developers pay CIL to help fund infrastructure provision in the locality, whilst planning agreements help mitigate the impact of their development and provide affordable housing. The experience of running a system of negotiated planning agreements alongside a non-negotiable infrastructure levy offers an opportunity to evaluate these policy shifts in order to assess their strengths and weaknesses and whether there are any wider lessons for international discussions of best practice in land value capture. Drawing on survey findings the paper considers the implementation of CIL alongside planning agreements, the revenue and expenditure patterns, and the impact of these combined land value capture mechanisms on development activity and, in particular, on affordable housing supply.     

Toward Disaster‐Resilient Cities: Characterizing Resilience of Infrastructure Systems with Expert Judgments

Resilient infrastructure systems are essential for cities to withstand and rapidly recover from natural and human‐induced disasters, yet electric power, transportation, and other infrastructures are highly vulnerable and interdependent. New approaches for characterizing the resilience of sets of infrastructure systems are urgently needed, at community and regional scales. This article develops a practical approach for analysts to characterize a community's infrastructure vulnerability and resilience in disasters. It addresses key challenges of incomplete incentives, partial information, and few opportunities for learning. The approach is demonstrated for Metro Vancouver, Canada, in the context of earthquake and flood risk. The methodological approach is practical and focuses on potential disruptions to infrastructure services. In spirit, it resembles probability elicitation with multiple experts; however, it elicits disruption and recovery over time, rather than uncertainties regarding system function at a given point in time. It develops information on regional infrastructure risk and engages infrastructure organizations in the process. Information sharing, iteration, and learning among the participants provide the basis for more informed estimates of infrastructure system robustness and recovery that incorporate the potential for interdependent failures after an extreme event. Results demonstrate the vital importance of cross‐sectoral communication to develop shared understanding of regional infrastructure disruption in disasters. For Vancouver, specific results indicate that in a hypothetical M7.3 earthquake, virtually all infrastructures would suffer severe disruption of service in the immediate aftermath, with many experiencing moderate disruption two weeks afterward. Electric power, land transportation, and telecommunications are identified as core infrastructure sectors.     

Reframing Resilience: Equitable Access to Essential Services

We urgently need to put the concept of resilience into practice if we are to prepare our communities for climate change and exacerbated natural hazards. Yet, despite the extensive discussion surrounding community resilience, operationalizing the concept remains challenging. The dominant approaches for assessing resilience focus on either evaluating community characteristics or infrastructure functionality. While both remain useful, they have several limitations to their ability to provide actionable insight. More importantly, the current conceptualizations do not consider essential services or how access is impaired by hazards. We argue that people need access to services such as food, education, health care, and cultural amenities, in addition to water, power, sanitation, and communications, to get back some semblance of normal life. Providing equitable access to these types of services and quickly restoring that access following a disruption are paramount to community resilience. We propose a new conceptualization of community resilience that is based on access to essential services. This reframing of resilience facilitates a new measure of resilience that is spatially explicit and operational. Using two illustrative examples from the impacts of Hurricanes Florence and Michael, we demonstrate how decisionmakers and planners can use this framework to visualize the effect of a hazard and quantify resilience-enhancing interventions. This “equitable access to essentials” approach to community resilience integrates with spatial planning, and will enable communities not only to “bounce back” from a disruption, but to “bound forward” and improve the resilience and quality of life for all residents.     

Spatial planning in small islands: the need to discuss the concept of ecological structure

The concepts of green infrastructure and ecological structure (ES) are current topics of discussion among the scientific community and spatial planners. ES is mandatory in Portugal in land-planning, such as municipal master plans, but no consensus has been reached on how to implement it. The concept has not yet been implemented in the Azores, a Portuguese autonomous region, even though the Region has the responsibility of adapting legislation or accomplishing the Portuguese legislature. This study presents a critical analysis of the available literature about ES and proposes a conceptual framework to define ES for small islands, which have unique characteristics, focusing on the Azorean archipelago. The conceptual framework meets the requirements of local legislation and uses an ecological function approach that is increasingly advocated in recent European recommendations. This framework is presented as a strategic and flexible way to identify both the important elements (recognized in current legislation) in a territory and the remaining potential of the territory. The framework also supports decision-making by allowing the identification of integrated solutions, decreasing trade-offs as much as possible and reconciling the needs of nature conservation and socioeconomic development. This framework could be applied to other small islands and other territories, with local adaptations.     

New Spatial Concepts Between Innovation and Lock-in: The Case of the Dutch Deltametropolis

It is often proclaimed that planning concepts serve an innovative function in the political process. They are praised as powerful tools that carry new insights and understandings into policy arenas. By examining the emergence and development of a new planning concept in the Dutch national spatial policy-making process, the deltametropolis concept, this paper questions this position. It argues that new spatial concepts tend to lose much of their innovative capacities when they enter the political arena and become encased in the traditional urban–rural planning discourse, thus reaffirming established planning orientations. The Dutch case of the deltametropolis illustrates that new spatial concepts may entail potential for innovation as much as for lock-in.     

Citizens' Anti-highway Revolt in Post-Pinochet Chile: Catalyzing Innovation in Transport Planning

During the last third of the 20th century, citizens throughout North America and Europe organized protests against urban highway projects, influencing urban transport planning in ways that shape its evolution to this day. With the globalization of car-centred urban planning models, some similar movements have emerged in developing countries. What, if anything, can they tell us about citizens' role in innovation to achieve more socially just, good and livable cities? Using a multidisciplinary approach grounded in planning theory and a local adaptation of participatory action research methods, this study explores lessons from an anti-highway movement in Santiago, Chile (1997). This study contributes citizens' perspective on crucial issues within the philosophy and history of city planning, examining shifts in governance that can significantly influence the potential for change in planning and city systems, even under adverse conditions. Is improving participation just a matter of ‘getting the process right’? This experience indicates that it requires re-formulating frameworks to encompass democratization, fostering multi-scalar, self-generating civil society organizations, and focusing on the role of organized citizens, rather than individuals, as they act on policy ecologies. The evidence from this Santiago case supports Portugali's argument that planning is both a profession, exercised by especially trained ‘experts’, and a skill exercised by citizens working from their everyday expertise. This example explores the mechanisms through which, even in a relatively hostile environment, self-generated citizen organizations may play a significant role in contesting business-as-usual debates and achieving innovative policies favouring greater equality and sustainability.     

Planning for urbanization in religious tourism destinations: insights from Shirdi,India

This paper examines the urbanization process in religious tourism destinations using the example of Shirdi in India. Shirdi, a town dedicated to worship of a twentieth-century Saint Sai Baba, attracts more than eight million visitors every year. The paper explains how religious tourism economy drives rapid urbanization including demographic change and land-use conversion owing to the infrastructure needs of visitors. It is found that planning mechanisms including the conventional master plan approach have been ineffective in adequately responding to issues such as the proliferation of unauthorized commercial establishments, hotels, lodging and boarding houses; strained infrastructure; and environmental pollution that characterize urbanization in religious tourism destinations.     

A Critical Reflection on the Experimental Method for Planning Research: Testing the Added Value of PSS in a Controlled Environment

For planning research to successfully generate usable mechanisms for planning practitioners more hypothesis-testing research designs are needed. Currently, the academic field seems more geared toward generating hypotheses, either by observing practice or from theoretical studies. This approach is especially common in research that generates knowledge of planning. In this paper, I map several relevant research designs that allow for such hypothesis testing and discuss their usability in planning research. Then, I particularly focus on the experimental method as a promising design for generating contextualized mechanisms for planning practice. I describe and analyze a study that aimed to develop mechanisms about the added value of knowledge technologies for the quality of planning. Two consecutive experiments are described in detail, after which the usability of the experimental method for planning research is discussed. Reflecting on these experiments indicate that the main strength of this research design is that it allows to create ideal circumstances for falsification (which is virtually impossible in planning practices. The main weakness is the ecological validity of findings, especially when the research is executed with students.     

EvacuAid: A Probabilistic Model to Determine the Expected Loss of Life for Different Mass Evacuation Strategies During Flood Threats

Evacuation of people in case of a threat is a possible risk management strategy. Evacuation has the potential to save lives, but it can be costly with respect to time, money, and credibility. The consequences of an evacuation strategy depend on a combination of the time available, citizen response, authority response, and capacity of the infrastructure. The literature that discusses evacuations in case of flood risk management focuses, in most cases, only on a best‐case strategy as a preventive evacuation and excludes other possible strategies. This article introduces a probabilistic method, EvacuAid, to determine the benefits of different types of evacuation with regards to loss of life. The method is applied for a case study in the Netherlands for preventive and vertical evacuation due to flood risk. The results illustrate the impact of uncertainties in available time and actual conditions (e.g., the responses of citizens and authorities and the use of infrastructure). It is concluded that preparation for evacuation requires adaptive planning that takes preventive and vertical evacuation into account, based on a risk management approach.     

Towards Next-Generation Urban Resilience in Planning Practice: From Securitization to Integrated Place Making

Resilience is a concept incorporating a vast range of contemporary risks and over recent years has become increasingly important to our understanding of contemporary planning policy and practice. This paper examines the changing nature of resilience strategies since 2000 and highlights how planners increasingly are asked to contribute to this agenda. Drawing on the emerging theories of urban resilience, this paper charts the emergence of different ‘styles’ of resilience over the last decade in the UK, with an emphasis on a range of policies associated with designing safer spaces. Emerging lessons are then deployed to highlight how a new generation of urban resilience practice is now emerging associated with embedding resiliency into local place-making activities. This paper concludes by reflecting upon the multiple uses of resilience in planning practice.     

e-Participation: Comparing Trends in Practice and the Classroom

This article reports an assessment of the growing use of Internet-based public participation methods, e-participation, in planning practice and university-level planning education in the USA. After documenting results from case study reviews of practice and a web-based survey of planning faculty, a comparative analysis reveals that academic programs are incorporating a range of e-participation tools; however, there is a need to increase curricula content to mirror trends in planning practice. The article concludes with recommendations on how to build on the strengths and to address the weaknesses observed in this study to better prepare students for the demands of planning practice.     

Production planning in a MRP/JIT repetitive manufacturing environment

Some literature suggests that the best approach to production planning is a complete implementation of just-in-time. It has also been suggested that JIT replaces material requirements planning, and computerized procedures are an unnecessary complex burden on management especially in a highly repetitive environment. This article examines the JIT programme at the John Deere Engine factory. In 1985 the factory began a JIT programme with the belief that it would replace their MRP system. The results of the JIT programme are examined and management's conclusion that the best approach is a blend of JIT and MRP is explored.     

Planning and Scheduling in Supply Chains: An Overview of Issues in Practice

This paper gives an overview of the theory and practice of planning and scheduling in supply chains. It first gives an overview of the various planning and scheduling models that have been studied in the literature, including lot sizing models and machine scheduling models. It subsequently categorizes the various industrial sectors in which planning and scheduling in the supply chains are important; these industries include continuous manufacturing as well as discrete manufacturing. We then describe how planning and scheduling models can be used in the design and the development of decision support systems for planning and scheduling in supply chains and discuss in detail the implementation of such a system at the Carlsberg A/S beerbrewer in Denmark. We conclude with a discussion on the current trends in the design and the implementation of planning and scheduling systems in practice.     

Decision analysis and risk models for land development affecting infrastructure systems

Coordination and layering of models to identify risks in complex systems such as large-scale infrastructure of energy, water, and transportation is of current interest across application domains. Such infrastructures are increasingly vulnerable to adjacent commercial and residential land development. Land development can compromise the performance of essential infrastructure systems and increase the costs of maintaining or increasing performance. A risk-informed approach to this topic would be useful to avoid surprise, regret, and the need for costly remedies. This article develops a layering and coordination of models for risk management of land development affecting infrastructure systems. The layers are: system identification, expert elicitation, predictive modeling, comparison of investment alternatives, and implications of current decisions for future options. The modeling layers share a focus on observable factors that most contribute to volatility of land development and land use. The relevant data and expert evidence include current and forecasted growth in population and employment, conservation and preservation rules, land topography and geometries, real estate assessments, market and economic conditions, and other factors. The approach integrates to a decision framework of strategic considerations based on assessing risk, cost, and opportunity in order to prioritize needs and potential remedies that mitigate impacts of land development to the infrastructure systems. The approach is demonstrated for a 5,700-mile multimodal transportation system adjacent to 60,000 tracts of potential land development.     

Integration of process planning and production planning and control in cellular manufacturing

Organisations willing to succeed in global competition have to integrate their internal and external processes. This especially includes planning and production control (PPC) processes. Optimised allocation of the production resources and quick response to demand changes result in lower cost and improvement of production performance. Practitioners and researchers have been trying to achieve these goals using production planning techniques. Although the results are significant, it seems necessary to integrate production operations in order to improve the production performance. The goals, information and decisions taken in production planning and control and process planning are often very different and difficult to integrate in Cellular Manufacturing (CM) environments. Designing an efficient PPC system and integrating it with process planning in a cellular environment is of the same importance. The following paper proposes first a comprehensive framework of integrated process planning and production planning and control in CM. Then, with respect to this framework and utilising the domain knowledge in the area of CM systems, an integrated model based on Integrated Definition Modeling Language is developed. The application of the models has been considered as a case study for a production system in electronics and telecommunication sector in a plant in Iran. The validity and completeness of the proposed model is tested by a panel of experts in the areas of production planning and control in CM environments.
