High growth is increasingly forcing development of hazard prone land in the coastal city of Tauranga.  A multi-hazard mapping tool developed to guide strategic growth planning in this natural hazard rich environment gives direct comparison of total hazard levels across the city. By aggregating individual hazards into a summative multi-hazard rating for each part of the city, urban planners and engineers have a decision support tool to aid city planning over the next 100 years. Tauranga growth requires 40,000 new homes over the next four decades in addition to the existing 57,000 homes. This 70% growth must squeeze within tight geographic constraints as Tauranga's 137,000 residents nestle around a harbour and are bound by open coast to the north and steep terrain to the south. This research quantifies Tauranga’s natural hazards of sea level rise, storm surge, coastal erosion, tsunami, earthquake shaking, liquefaction, landslides volcanic ashfall and flooding. Each hazard is spatially represented through hazard maps. Individual hazards are combined into a multi-hazard model to represent the aggregated hazard exposure of each point of the city. The multi-hazard exposure is spatially mapped using GIS allowing an area with tsunami, liquefaction and storm surge as dominant hazards to be directly compared with an area of different hazards such as flooding and landslides. Mapping of these hazards provides strategic input for building city resilience through land use planning and mitigation design. A pilot study area of 25 km2 selected from the Tauranga City Council total area of 135 km2 demonstrates the accumulated mapping approach. The pilot area contains a thorough representation of geology, elevation, landform and hazards that occur throughout the city. Our findings showed the highest aggregated hazard areas in Tauranga are along the coast. As is common with many beach resort towns this corresponds with the most popular living areas. The lower hazard areas suitable for urban growth are distributed mostly away from the open coast in the slightly elevated topography.

Deindustrialization and rapid population growth in the City of Toronto has resulted in greater employment land conversion pressures being placed on underutilized and vacant Employment Areas (Blais, 2015; Filon 2003). In 2013, City Planning Staff made recommendations to City Council for the preservation or conversion of specific employment land application requests under the City of Toronto’s Municipal Comprehensive Review process (City of Toronto, 2013). This paper will examine five employment land conversion applications in Toronto’s inner suburbs, the Scarborough Urban Growth Centre and within 500 meters of the Mimico GO Station through a content analysis of City Planning Staff’s recommendations along with the property owner’s rationales. It was found that the five sites should be converted to better meet the Provincial and Municipal planning policy requirements that align with Smart Growth’s objectives. The five sites pose minimal land use compatibility conflicts, require increases in population and employment density, and are isolated from larger Employment Areas.

Abstract Land use planning in an area will refer to the regulations that have been established by the City Planning Office of each region. This is because each region has the authority to plan spatial plans in their respective regions. The border area is an area whose land use can be influenced by two different regional regulations. This is because the border area is a special area located on the border between two regions, each of which has spatial planning regulations. Gayungan District is one of the sub-districts included in the Border Area between Surabaya City and Sidoarjo Regency. To prevent overlapping spatial regulations that may occur in Gayungan District, it is necessary to monitor the suitability of land use using geographic information system technology and remote sensing. The data used in this study are the 2019 Gayungan District RDTRK Map and very high resolution satellite imagery of Pleiades Surabaya City 2019. The method used is the Object Based Image Analysis (OBIA) method. The result of this research is the suitability of land use in Gayungan District. A land use can be said to be suitable if the existing land use is in accordance with the land use in the plan. Meanwhile, land use is said to be inappropriate if the existing land use is different from the planned spatial use. All land use classes in Gayungan District in 2019 had a higher percentage of unsuitable land than the percentage of suitable land. Each percentage of land is not suitable for each land use class, namely: water body class by 92.593%, road class by 78.035%, industrial class by 77.838%, defense class by 76.706%, green open space class by 69.736%, and residential class by 52,27%. So it can be said that the land use in Gayungan District in 2019 was not in accordance with the plans in the City Spatial Detail Plan Map for 2018-2038, but the land use could be appropriate in its designation for the future, because there is a possibility of development for residential class, industrial class, and defense class on open land that is still widely available.

Floods are amongst the most frequent and destructive type of disaster, causing significant damage to communities. Globally, there is an increasing trend in the damage caused by floods generated by several factors. Flooding is characterized by the overflow of water onto dry land. Tropical cyclones generate floods due to excess water in rivers and streams and storm surges; however, the hazard of both phenomena is presented separately. In this research we present a methodology for the estimation of flood hazards related to tropical cyclones, integrating runoff and storm surge floods. As a case study, we selected the south-western suburbs of the city of La Paz, the capital of the state of Baja California Sur in northwest Mexico. The city has experienced in recent years an expansion of the urban area. In addition, there is an infrastructure of great importance such as the transpeninsular highway that connects the capital with the north of the state, as well as the international airport. Our results indicate that urban areas, agricultural lands, as well as the air force base, airport, and portions of the transpeninsular highway are in hazardous flood areas, making necessary to reduce the exposure and vulnerability to these tropical cyclone-related events. A resulting map was effective in defining those areas that would be exposed to flooding in the face of the impact of tropical cyclones and considering climate change scenarios, which represents an invaluable source of information for society and decision-makers for comprehensive risk management and disaster prevention.

In 1989 Odin Teatret established the Holstebro Festive Week (Denmark), and did so by involving the entire city and its inhabitants. The Festive Week promptly became an on-going event, which takes place every three years in June. What characterises the Holstebro Festive Week in particular? And how has this event influenced the city and its citizens in the longer run? In other words, how can an event like the Festive Week contribute to enriching a city for more than just a week? When I interviewed the Mayor about the Festival and the theatre’s role in the event, he said: “What the theatre brings us is popular and I think it is crucial that we get common experiences in which we can mirror ourselves – in the selfish society we are currently living in. In Holstebro we have become dependent on Odin Teatret, which makes us take part and which has become a common denominator for the entire city. It is a gift that we have Odin Theatret” (interview with the author, June 2011). 1 It is a rather unusual statement for a mayor to make that a theatre is a gift for a city and that it has become a ‘common denominator’ 2 for the city – and, what is more that the city has become dependent on the theatre. In this chapter I will reveal and explore how Odin Teatret involves the entire city. I will try to give a clear answer as to why the Mayor described the theatre as a ‘common denominator’. In my investigation of the theatre’s approach to the Festive Week I use my personal experience and knowledge from my time as assistant manager at the theatre (1987-88). Most of my research has been carried out in the form of field studies conducted during the Festival Weeks in 2008 and 2011. During both festivals I spent one week in Holstebro and the surrounding villages watching and observing how the local audience responded to the activities. In addition I carried out a series of semi-structured interviews with representatives from Holstebro: the head of police, the Deputy Mayor, the director of a travel agency, a librarian, a policeman, the Chairman of the Cultural Affairs Committee of the City Council, the head of city planning, the project leader from the Odin Theatre and a senior lecturer living in Holstebro and working at Aarhus University and finally the Mayor.

In the article, the author has focused on analyzing the current state of land use by types of enterprises’ economic activity, regional economic and financial data to propose a new robust model for cost-effective land use planning for commercial and non-commercial enterprises. The research results can serve as an important material for the decision-making process on how to develop the land and the city areas in the context of new global economic development. It provides extensive overview of existing land use trends for Kyiv city based on analytical data and scientific assumptions. The author believes that this research will be beneficial for government organizations, local government authorities, international organizations, private institutions, and researchers. The goal of the research paper is to build a solid scientific model based on a general understanding of underlying economic challenges of efficient land use considering past data, short-term and long-term planning. The paper has an overview of city planning documentation and city statistical data in the context of real estate, urban population, economic data, including research of real estate and currency exchange rate data to median salary in Kyiv starting from the 2000s. It is important not to put too much focus on the existing models and systems, as they rely too much on the assumptions and complicated calculations that are hard to make use of in real-world planning. Instead, we build our research on real-world data and developed a forecast for the size of investment in land use, average real estate prices for the next 5 years. The paper noted an existing problem of inconsistency of the existing norms and regulations in Ukraine concerning rational and effective land use and planning, especially for local authorities and commercial organizations. The author substantiates why the economy in the context of urbanization needs a new look. The paper uses the planning of Kyiv city. It is a suitable example of a developing city, so the proposed model can be developed based on the city’s economic and land use data. This research can help solve the existing problems of urbanization in Ukraine and have a positive impact on the economic development of the city and the region.

City planning has become such an acknowledged function of city government that today we tend to take the city planning commission for granted as a logical part of the city government. Pioneers in the city planning movement in the United States at the turn of the century, however, had yet to decide upon the proper vehicle for carrying out city planning. Although in the early years of the movement a variety of methods were tried, including private planning associations, planning conducted by a committee of city council, and city planning conducted by a single city official, the most common agency of planning to emerge out of this period was the city planning commission.

New strategies to improve the quality of urban pedestrian environments are becoming increasingly important in sustainable city planning. This trend has been driven by the advantages that active mobility provides in terms of health, social, and environmental aspects. Our work explores the idea of walkability. This concept refers to the friendliness of the urban environment to pedestrian traffic. We propose a framework based on the multi-criteria decision analysis (MCDA) methodology to rank streets in terms of walkability levels. The city of Lisbon (Portugal) is the location of the streets under examination. Findings confirmed the framework’s replicability and suggested the possibility of this strategy being used as a support tool for designing urban policies.

Place branding is a network of associations in the consumer’s mind, based on the visual, verbal, and behavioral expression of a place. Food can be an important tool to summarize it as it is part of the culture of a city and its symbolic capital. Food is imaginary, a ritual and a social construction. This paper aims to explore a ritual that has turned into one of the brands of Lisbon in the past few years. The fresh sardines barbecued out of doors, during Saint Anthony’s festival, has become a symbol that can be found on t-shirts, magnets and all kinds of souvenirs. Over the year, tourists can buy sardine shaped objects in very cheap stores to luxurious shops. There is even a whole boutique dedicated to the fish: “The Fantastic World of Portuguese Sardines” and an annual competition promoted by the city council to choose the five most emblematic designs of sardines. In order to analyze the Sardine phenomenon from a city branding point of view, the objective of this paper is to comprehend what associations are made by foreigners when they are outside of Lisbon. As a methodological procedure five design sardines, were used of last year to questioning to which city they relate them in interviews carried in Madrid, Lyon, Rome and London. Upon completion of the analysis, the results of the city branding strategy adopted by the city council to promote the sardines as the official symbol of Lisbon is seen as a Folkmarketing action. The effects are positive, but still quite local. On the other hand, significant participation of the Lisbon´s dwellers in the Sardine Contest was observed, which seems to be a good way to promote the city identity and pride in their best ambassador: the citizens.

How did Edinburgh become ‘festival city’? Despite appearances, it was not always so, and it acquired the accolade by happenstance; in the view of one observer, a ‘strange amalgam of cultural banditry, civic enterprise and idealism’. The official Festival's survival was down to the City Council, and it was funded almost entirely by public bodies. This was the central structure around which The Fringe developed, and The Traverse prospered, along with smaller festivals and events to become Festival City. The story sheds considerable light on how Edinburgh ‘works’, its strengths and weaknesses combined.
