“…Urbanization improves the residents' living standards because urban development can improve living conditions and provide more public services, such as transportation, parks, and shopping plazas [10]. However, urbanization also causes many environment problems, such as global warming, water pollution, air pollution, greenhouse gas emissions, enhanced urban heat island effects, and industrial wastes [2,[11][12][13]. In addition, ecological degradations resulting from urban expansion, such as the loss of biodiversity and climate changes, can also exert an influence on local and global ecosystem services, which will eventually affect the ability to sustain urban development [5,6].…”

The Guangdong–Hong Kong–Macau Greater Bay Area (GBA) of China is one of the major bay areas in the world. However, the spatiotemporal characteristics and rationalities of urban expansions within this region over a relatively long period of time are not well-understood. This study explored the spatiotemporal evolution of 11 cities within the GBA in 1987–2017 by integrating remote sensing, landscape analysis, and geographic information system (GIS) techniques, and further evaluated the rationalities of their expansion using the urban area population elastic coefficient (UPEC) and the urban area gross domestic product (GDP) elastic coefficient (UGEC). The results showed the following: (1) Guangzhou, Shenzhen, Foshan, Dongguan, Zhongshan, and Zhuhai experienced unprecedented urbanization compared with the other cities, and from 1987 to 2017, their urban areas expanded by 10.12, 11.48, 14.21, 24.90, 37.07, and 30.15 times, respectively; (2) several expansion patterns were observed in the 11 cities, including a mononuclear polygon radiation pattern (Guangzhou and Foshan), a double-nucleated polygon pattern (Macau and Zhongshan), and a multi-nuclear urbanization pattern (Shenzhen, Hong Kong, Dongguan, Jiangmen, Huizhou, Zhaoqing, and Zhuhai); (3) with regard to the proportion of area, the edge-expansion and outlying growth types were the predominant types for all 11 cities, and the infilling growth type was the one of the important types during 2007–2017 for Shenzhen, Hong Kong, Dongguan, Zhongshan, and Foshan; (4) the expansion of most cities took on an urban-to-rural landscape gradient, especially for Guangzhou, Shenzhen, Foshan, Zhongshan, Dongguan, and Zhuhai; and (5) the rationalities of expansion in several time periods were rational for Guangzhou (1997–2007), Hong Kong (2007–2017), Foshan (1987–2007), Huizhou (1987–1997), and Dongguan (1997–2007), and the rationalities of expansion in the other cities and time periods were found to be irrational. These findings may help policy- and decision-makers to maintain the sustainable development of the Guangdong–Hong Kong–Macau Greater Bay Area.

“…through less use of fossil fuels, especially for transport What Makes a Compact City? Differences Between Urban Research in the Global North and the Global South (Zhu 2012;Kotharkar et al 2014;Wang 2014;Abdullahi et al 2015b;Radulovic et al 2015). Again, these arguments seem as relevant also for Global North or BRICS country contexts while issues, such as passive solar design (Kotharkar et al 2012) and the need for direct sunlight as main source of light (Freewan et al 2014) appear particularly relevant in Global South informal settlements.…”

Compact cities are promoted in policy as a response to current societal challenges, but it is unclear or ambiguous what qualities or benefits a compact city is supposed to deliver. The concept of the compact city is widely debated in the research literature, and there are numerous arguments both for and against compact cities. However, many studies or reviews tend to apply a delimited approach, discussing a confined number of qualities or basing the assessment on fairly narrow empirical material. Research is also carried out from within a number of separate disciplines or “discourses”. This paper aims to provide a clearer and more consolidated understanding of the wide spectrum of qualities that make up the compact city in support of better planning, governance and management of cities in the Global South. The objective is to present a review of current articles discussing the compact city in order to capture similarities and differences in the academic discourse between Global North and Global South contexts, and to outline a comprehensive compact city taxonomy. This is achieved by answering three questions: (1) What types of urban qualities are discussed in scientific articles studying urban compactness? (2) (How) do articles focusing on Global North and Global South contexts differ when it comes to exploring compact city qualities? and (3) Do the findings indicate areas of research withing the broader scope of urban compactness where research should be initiated or strengthened? The analysis is based on literature searches in the Scopus database for 2012-2015 using the search term “compact city”. A quantitative assessment was carried out, sifting out what terms are used to label purported (or debated) qualities of compact cities. Papers are sorted into different categories according to geoeconomic context (i.e. Global North, BRICS, Global South). The outcome is an extended taxonomy of compact city qualities, including twelve categories. Weaknesses in compact city research aimed at cities in the Global South were identified, linked in particular to nature, health, environmental issues, quality of life, sociocultural aspects, justice and economy, as well as a significant lack of compact city research linked to urban adaptability and resilience.

“…22 However, the benefits of vegetation in relation to water storage, cooling and human health should be expressed for each study case separately, since they depend on a number of factors including soil properties, type of vegetation spaces and spatial planning. The research 23 determined that the expansion of the urban morphological zones, mainly along traffic arteries, is able to intensify the UHI. Furthermore, the size of unsealed soils and their average Euclidean distances within urban morphological zones indicate the potential to lower the temperature on the microlevel.…”

Indisputably, urban design and soil sealing are parameters that can either aggravate or mitigate the urban heat island phenomenon, observed in dense urban environments around the world. Large sealed surfaces have been extensively reported to induce higher surface temperatures. The aim of this work is to answer a critical scientific question: on what extent do actually sealed soils contribute to the urban heat island. As an example, a case study was developed for the case of Nicosia – a city that experiences high urban heat island intensities due to its geographical location and its continuous urban growth. Three scenarios were developed with ranging percentages of unsealed surfaces – 0%, 20% and 40% of vegetation coverage and were simulated in an established microclimate modelling tool ENVI-met. The effect of the urban design and soil sealing in the investigated scenarios was analysed by presenting the results for a range of parameters, including ground- and canopy-level temperatures, diffused and reflected radiations, relative humidity, wind speed and sky view factor. The results indicated that the most effective scenario is the case where 40% of the ground is unsealed, primarily due to the impact on the canopy-level temperature and the wind speed. The authors believe that more attention should be drawn to this alarming topic by both policy-makers and researchers.
