Urbanization is spreading across the world and beyond metropolitan areas. Medium-sized cities have also undergone processes of accelerated urban expansion, especially in Latin America, thanks to scant regulation or a complete lack thereof. Thus, understanding urban growth in the past and simulating it in the future has become a tool to raise its visibility and challenge territorial planners. In this work, we use Markov chains, cellular automata, multi-criteria multi-objective evaluation, and the determination of land use/land cover (LULC) to model the urban growth of the city of Temuco, Chile, a paradigmatic case because it has experienced powerful growth, where real estate development pressures coexist with a high natural value and the presence of indigenous communities. The urban scenario is determined for the years 2033 and 2049 based on the spatial patterns between 1985 and 2017, where the model shows the trend of expansion toward the northeast and significant development in the western sector of the city, making them two potential centers of expansion and conflict in the future given the heavy pressure on lands that are indigenous property and have a high natural value, aspects that need to be incorporated into future territorial planning instruments.

Ukraine is an associate member of the European Union and in the coming years it is expected that all data and services already used by EU countries will be available to Ukraine. The lack of quality national products for assessing the development and planning of urban growth makes it impossible to assess the impact of cities on the environment and human health. The first steps to create such products for the cities of Ukraine were initiated within the European project "SMart URBan Solutions for air quality, disasters and city growth" (SMURBS), in which specialists from the Space Research Institute of NAS of Ukraine and SSA of Ukraine received the first city atlas for the Kyiv city, which was similar to the European one. However, the resulting product had significantly fewer types of land use than the European one and therefore the question of improving the developed technology arose. The main purpose of the work is to analyze the existing technology of European service Urban Atlas creation and its improvement by developing a unified algorithm for building an urban atlas using all available open geospatial and satellite data for the cities of Ukraine. The development of such technology is based on our own technology for classifying satellite time series with a spatial resolution of 10 meters to build a land cover map, as well as an algorithm for unifying open geospatial data to urban atlases Copernicus. The technology of construction of the city atlas developed in work, based on the intellectual model of classification of a land cover, can be extended to other cities of Ukraine. In the future, the creation of such a product on the basis of data for different years will allow to assess changes in land use and make a forecast for further urban expansion. The proposed information technology for constructing the city atlas will be useful for assessing the dynamics of urban growth and closely related social and economic indicators of their development. Based on it, it is also possible to assess indicators of achieving the goals of sustainable development, such as 11.3.1 "The ratio of land consumption and population growth." The study shows that the city atlas obtained for the Kyiv city has a high level of quality and has comparable land use classes with European products. It indicates that such a product can be used in government decision-making services.

The City

For over A half-century America has been an urban nation. However, a significant upsurge of concern for the cities has generally not accompanied the increasing acknowledgment of the country's urban status. In large measure, any serious governmental concern for American cities has been halfhearted. Attempts have been made to confront the problems of the nation's cities. Planners, enlightened city officials, and others have faced the intrinsic difficulty of bringing together thousands, and often millions, of individuals in a single municipal unit sometimes with limited success; but more often such attempts have been well-intentioned failures. Americans have yet to develop a consistent or coherent approach either to current urban dilemmas or to the future roles we envision for our cities. Though there are a multitude of regulations for almost every aspect of urban life, the phenomenon called “the city” continues to be as problematic for us today as it was for earlier generations of urban dwellers.

Purpose This paper aims to understand the paradoxal development in Buenos Aires, Argentina, where economic growth was not accompanied by improved housing access. The period between the years 2003 and 2013 was characterized by a sustained economic growth with social inclusion and a great expansion of both social and private housing supply in the cities of Argentina. However, this growth was not accompanied by an improvement in the overall access to land and housing. On the contrary, the habitation problems in terms of access to formal, environmentally safe and well-located land with decent facilities have worsened. The City of Buenos Aires is one of the places where this paradox is most manifested. Design/methodology/approach The functioning of the land markets and the real estate development in Buenos Aires will be analyzed in the period 2003-2013 in relation to the macroeconomic context, the monetary effort for the acquisition and rent of a formal dwelling and certain logics of urban development. Findings The rhythm of urban land valorization continuously surpassed that of other commodities and services. The expansion of residential production did not improve the access to formal housing. On the contrary, habitation issues have worsened and conflicts concerning access to land, housing and the city have rapidly increased since 2003. Originality/value In a Latin American context, this paper is the first to establish a conceptual relationship based on empirical data between land price dynamics and real estate development. The paper is also original in its identification of a change in valorization rhythm and pattern of real estate development in the past decade (2003-2013).

ResumenLa extracción de la sal en la puntilla se ha venido desarrollando desde 1763, y ha sido un motor económico y medio para proveer de recursos a familias que artesanalmente se dedicaban a ella. Las salinas de la Provincia de Santa Elena conforman un ecosistema en el que convivencomunidades vegetales y especies endémicas y constituyen uno de los paisajes naturales más singulares de la provincia.En la actualidad el paisaje salinero se ha visto reducido en las últimas décadas por la expansión urbana y la carencia de políticas de estado que contemplen su conservación. El presente trabajo de investigación muestra el análisis de la situación de las salinas marinas, emplazadas en la costa de la ciudad de Salinas, centrándose en los cambios que han presentadoen los últimos años, debido a los procesos de urbanización. Desde una perspectiva histórica y etnográfica se describe el funcionamiento y  métodos de extracción de la sal; para la identificación y clasificación de las salinas tanto industriales como artesanales. El estudio comprende lavariación en la extensión de las salinas, y si son contempladas en las estrategias de protección frente al crecimiento urbano en los instrumentos normativos municipales.AbstractSalt extraction in The Salinas has been developing since 1763 and has been an economic and an engine to provide resources to families who were handcrafted engaged in it. The Salina’s municipality make up an ecosystem in which plant communities and endemic species coexist andconstitute one of the most unique provinces’s natural landscapes.Today the salt landscape has been reduced in recent decades by urban expansion and the lack of State Policies that contemplate its conservation. This research paper shows the analysis of the the salt marshes’s situation, located on the coast of the city of Salinas, focusing on the changes theyhave presented in recent years, due to urbanization processes. From a historical and ethnographic perspective, the operation and methods of salt extraction are described, for the identification and classification of both industrial and handcrafted salt flats. The study comprises the variation in the extension of the Salinas, and if they are contemplated in the strategies of protection against the urban growth in the normative instruments of the municipality.Salinas as a city its contemplating the implementation of strategies for protection of these ecosystems against the urban growth in the normative instruments of the municipality.

Abstract. The fastest urbanization is occurring in the Global South which includes many developing nations in Asia. However, a rapid and unplanned urban growth could threaten the sustainability of the process. A key step towards a sustainable urban development is to better understand interdependencies amongst urban growth patterns, infrastructure and socio-economic indicators. Here we chose Bangkok, Thailand as a megacity case study to assess the spatio-temporal urban growth dynamics and specifically its dependency with road density at intra-city scales. The SLEUTH urban growth model is further applied for predicting future expansion over the next decade and to assess the future intra-city expansion. Urban expansion patterns for Bangkok were generated for 1987 and 2017 using Landsat derived urban land-cover maps. Open Street Map (OSM) is used to generate a 2017 road density map. The urban expansion (1987–2017) was observed to follow a radially outward expanding pattern inland, with the logarithmic urban expansion rate having an inverted concave trend with road density. The rising/falling limbs then indicated an increase/decrease of urban expansion for which a road density “turning point” is readily identified and further used to develop a road density-based zoning map that highlights the different intra-city urban expansion rates. The SLEUTH predicted urban growth till year 2027 which also showed expansion outward from existing urban areas. The future expansion trend is also consistent with the turning point trend. This study showed that such spatial-temporal analysis of urban expansion coupled with SLEUTH can be useful for investigating likely outcomes of city development plans.

Current rapid urbanization trends in developing countries present considerable challenges to local governments, potentially hindering efforts towards sustainable urban development. To effectively anticipate the challenges posed by urbanization, participatory modeling techniques can help to stimulate future-oriented decision-making by exploring alternative development scenarios. With the example of the coastal city of Monastir, we present the results of an integrated urban growth analysis that combines the SLEUTH (slope, land use, exclusion, urban extent, transportation, and hill shade) cellular automata model with qualitative inputs from relevant local stakeholders to simulate urban growth until 2030. While historical time-series of Landsat data fed a business-as-usual prediction, the quantification of narrative storylines derived from participatory scenario workshops enabled the creation of four additional urban growth scenarios. Results show that the growth of the city will occur at different rates under all scenarios. Both the “business-as-usual” (BaU) prediction and the four scenarios revealed that urban expansion is expected to further encroach on agricultural land by 2030. The various scenarios suggest that Monastir will expand between 127–149 hectares. The information provided here goes beyond simply projecting past trends, giving decision-makers the necessary support for both understanding possible future urban expansion pathways and proactively managing the future growth of the city.

The 'prodigious decade' of Spanish urbanism caused a large expansion of urban lands, but also a much greater amount of planned but undeveloped land. The planning for this 'expectant city' is a challenge for the future of our cities. In this work, the streets proposed in these plans are analysed by evaluating their dimensional characteristics (surface and width) and their habitability (pedestrian-cyclist space and previsions of tree lines). The research is focused on the city of Murcia, paradigmatic case of the expansive urbanism typical of the real estate bubble. We have studied 2,096 streets from 92 partial plans approved during the period 2002-2013. The results show how the analysed variables change according to the use and density of the sectors and can be useful to evaluate the improvement of the habitability of these streets before their execution.

In recent years, the authorities of Puerto Vallarta have embarked on an urban regeneration pro‑ cess that allows real estate developers to excessively build apartments for tourism purposes, as evidence by the current situation in two of the iconic places in the destination: The Romantic Zone and Marina Vallarta. The objective of the work is to analyze the touristification process that the city faces as a result of real estate development and the transformation of housing and commerce in these areas. The study is of a mixed type and includes discourses about the modernization of the city and the perception of residents in local newspa‑ pers, the results of which show the accelerated process of touristification facing the city.
