Exploiting the Urban System? The Frictions of Military Finance and Diplomacy in the Dutch Republic, 1688–1714

This article examines how international military finance operated in the Dutch Republic between 1688–1714. The region’s unique urban geography in which the political and financial infrastructures crucial for military financing were geographically dispersed created stresses and strains. These inconveniences were overcome due to the Republic’s excellent intra-urban infrastructure – creating fast and reliable communication between the different urban centers – and their reliance on (semi-)private agents, the solliciteurs-militair. As a result, the urban system created a level of flexibility: credit for military purposes could be found both in The Hague and Amsterdam, rather than having to rely on a single city as was the case in London. This focus on the urban has broader historiographical importance because recent scholarship on early modern war and state formation is increasingly questioning whether the focus on political and financial centralization is necessarily the best way to understand these processes.

A multi-scale integrated assessment model to support urban sustainability

Tools purposed towards supporting the transition to more sustainable urban futures typically focus on specific phenomena at the local level. Whilst such approaches remain valuable, there is a need to complement this micro approach with broader integrated methods which deal with the interaction between different urban components as well as their relation to processes and policies enacted at higher scales. Through the adaptation of the World3 global model of Meadows et al. (The limits to growth, Universe Books, New York, 1972; Limits to growth: the 30-year update. Earthscan, London 2005), integrating both an urban system layer, and a national data layer inputting new data, we develop a proof-of-concept multi-scale integrated assessment model. This model is used to explore the relationship between the sustainability of the urban system relative to higher-scale contexts. By emphasising feedback, cascading effects, and unintended consequences, such a modelling framework allows for deeper consideration of coupling mechanisms between subsystems both within the urban system and across broader scales. Following the description of our model, we take Meadows et al. (2005)’s ‘Scenario 3’ as a starting point to generate several scenarios exploring potential intervention taken at the level of the individual urban system to tackle food security and localised pollution. Our results demonstrate that the evolution of the urban system is sensitively dependent on wider global events, and that while concerted intervention may mitigate some effects, the future of an individual system is largely at the mercy of the evolution of the global system. We argue that the results of this exercise suggest an important role for multi-scale models for informing the wider context of policy measures taken across different hierarchical scales. In an extended discussion section, we outline barriers and potential routes for building our work beyond a proof-of-concept relating to data, boundaries, politicisation, and building confidence in model outputs.

Impact of construction activities on the environment of cities

Methods of reducing damage to the environment during construction, territorial planning, as well as measures for the improvement of territories aimed at its restoration are considered. The environmental problems of a large city and the assessment of the impact of urban planning objects on the environment have been studied in detail. The paper shows the need to revise the traditional principles of the formation of the urban framework. The paper rightly notes that if earlier much attention was paid to the formation of a technogenic framework of the city – a life support system consisting of transport and engineering infrastructures of the city, today the formation of the ecological framework of the city is becoming increasingly important. The high importance of the ecological (water-green) frame of the city as a system is determined by the fact that water bodies and adjacent territories, “green open” spaces can significantly affect the quality and state of the urban environment, and with careful thought-out, the formation of the ecological frame will help to ensure the integrity of the entire natural and technical urban system.

Population mobility and sustainable development in the Mamminasata Metropolitan South Sulawesi, Indonesia

Economic growth and urban agglomeration have triggered an increase in the size and mobility of the Metropolitan Mamminasata urban population. This study aims to analyse spatial interactions working as a determinant of connectivity of the transportation system and the growth of suburban areas toward smart and sustainable cities in the Mamminasata Metropolitan urban system and the effects that spatial expansion, spatial integration, urban agglomeration, spatial use, and the transportation system have on population mobility. The research method used is a sequential explanatory design that combines quantitative and qualitative research methods. The results show that the coefficients of determination are as follows: spatial expansion to population mobility – 4.90%, spatial integration to population mobility – 2.99%, spatial interaction to population mobility – 4.87%, urban agglomeration to population mobility – 2.09%, space use to population mobility – 2.64%, and transportation system to population mobility – 5.15%. The results of this study will assist in the formulation of development policies, management of the urban transportation system, and allocation of space utilisation going forward.

Vulnerability and Resilience of Urban Traffic to Precipitation in China

The concept of Healthy Cities, introduced by the World Health Organization, demonstrates the value of health for the whole urban system. As one of the most important components of urban systems, transportation plays an important role in Healthy Cities. Many transportation evaluation systems focus on factors such as road networks, parking spaces, transportation speed, accessibility, convenience, and commuting time, while the vulnerability and resilience of urban transportation are rarely evaluated. This study presents the preliminary progress in the evaluation of traffic vulnerability and resilience during precipitation events in 39 Chinese cities. Traffic congestion index data, derived from the Baidu Map Smart Transportation Platform, and rainfall data, derived from NASA’s global precipitation measurement, are utilized. Traffic vulnerability index, traffic resilience index, and the corresponding quantitative methods are proposed, and the analysis results are presented. This study is of value in improving the understanding of urban traffic vulnerability and resilience, and in enabling the quantitative evaluation of them in urban health assessment and the Healthy Cities program.

Resilience and Urban Regeneration Policies. Lessons from Community-Led Initiatives. The Case Study of CanFugarolas in Mataro (Barcelona)

This paper addresses socio-ecological, community-led resilience as the ability of the urban system to progress and adapt. This is based on the socio-cultural, self-organized case study of CanFugarolas in Mataró (Barcelona), for the recovery of a derelict industrial building and given the lack of attention to resilience emerging from grassroots. Facing rigidities (stagnation) observed under the provisions of urban regeneration policies (regulatory realm), evidenced in the proliferation of urban voids (infrastructural arena), the social subsystem stands as the enabler of urban progression. Under the heuristics of the Adaptive Cycle and Panarchy, the study embraces Fath’s model to analyze the transition along, and the interactions between, the adaptive cycles at each urban subsystem. The mixed method approach reveals the ability of the community to navigate all stages and overcome successive ailments, despite seemingly insurmountable obstacles (traps) at the physical support (built stock) and the regulatory arena (urban planning). Further, cross-scale, social-centered interactions (panarchy) are also traced, becoming the “sink” and the “trigger” of the urban dynamics. The community, in the form of an actor-network, becomes the catalyst (through Remember/Revolt) of urban resilience at the city scale. At a managerial level, this evidences its temporal and spatial complementarity to top-down urban regeneration policies.

Identifying Urban Functional Areas in China’s Changchun City from Sentinel-2 Images and Social Sensing Data

The urban functional area is critical to an understanding of the complex urban system, resource allocation, and management. However, due to urban surveys’ focus on geographic objects and the mixture of urban space, it is difficult to obtain such information. The function of a place is determined by the activities that take place there. This study employed mobile phone signaling data to extract temporal features of human activities through discrete Fourier transform (DFT). Combined with the features extracted from the point of interest (POI) data and Sentinel images, the urban functional areas of Changchun City were identified using a random forest (RF) model. The results indicate that integrating features derived from remote sensing and social sensing data can effectively improve the identification accuracy and that features derived from dynamic mobile phone signaling have a higher identification accuracy than those derived from POI data. The human activity characteristics on weekends are more distinguishable for different functional areas than those on weekdays. The identified urban functional layout of Changchun is consistent with the actual situation. The residential functional area has the highest proportion, accounting for 33.51%, and is mainly distributed in the central area, while the industrial functional area and green-space are distributed around.

The Role of Urban Informatics in Monitoring the Physical Deteriortion of Urban Environment

The twenty-first century is witnessing a rapid growth population in urban areas; this growth needs intelligent urban planning and management. The field of urban informatics is one of the new and vital specialties to organize and analyse the urban system at all levels and areas. ICT works with interactive community participation to guide and manage the urban environment to serve, provide the residents with safety and security. The paper presents a new vision in terms of employing the field of urban informatics in mapping and monitoring the urban deterioration of the built environment in general and buildings in particular. The urban informatics system is still taking its first steps to manage and serve the city's facilities (transportation, communication, air pollution, etc.). The built environment and the deterioration through time and other factors are still far from this area. This paper aims to identify the urban information field, the situations, and types of urban deterioration and move to capture urban deterioration indicators (main and secondary), which can be measured in urban informatics. This paper recommends the adoption of such a mechanism in managing and controlling the deterioration that contributes to the reduction of material and human losses, saving time and money away from traditional methods, and the possibility of employing them in times of crisis and disasters in the urban environment.

New insights into the settlement patterns of the capital city at Erlitou

By examining the structural components, settlement plan, and developmental trajectory of the capital city at Erlitou, it is possible to explore the emergence of the state, kingship, and accompanying characteristics. Erlitou has been subjected to intensive excavation, revealing roads, walls, huge sacrificial pits, and palatial buildings with multiple courtyards as indicated by foundation No. 5. As to the developmental trajectory of the settlement pattern, all principal components of a capital city appeared in phase II of the Erlitou culture. A layout based on intersecting roads also formed, thus laying a foundation for the plan of an urban center in later periods. The open urban system formed during the Erlitou period changed to a closed system during later periods. The Erlitou site went through an initial phase during which it flourished as a capital city, then a period when principal urban components were gradually abandoned. The site became a high-ranking settlement during the early Erligang period. There is a relationship between the changes through time in pottery typology and the development of the settlement pattern. Kin-based residential and burial areas define the spatial division of the capital city at Erlitou. The mode of craft production is characterized by a large-scale workshop enclosure along with small-scale production sites.
