Numerous cities around the world are facing the problem of land subsidence. In many cases, it is the excessive groundwater extraction to meet human needs that leads to this subsidence. Since land subsidence rates are very slow (a few centimeters per year), the subsidence usually remains unnoticed until it has progressed to the point of causing severe damage to buildings, houses, and/or other infrastructures. Therefore, it is very important to detect the presence of subsidence in advance. In this study, screening for the presence of land subsidence in the city of Denpasar, Bali, Indonesia is conducted. The Sentinel-1A/B SAR dataset, taken from October 2014 to June 2019, is processed using the SBAS DInSAR method. Subsidence is found in the districts of Denpasar Selatan, Denpasar Barat, and Kuta, which falls in the range of -100 mm to -200 mm in an area of about 93.03 ha. All the extracted points of interest show the subsidence having linear behavior. The spatio-temporal behavior of the subsidence in Denpasar is presented clearly. However, the mechanism and the deriving factors of the subsidence remain unclear. Therefore, further studies are needed.

Since the early 1990s, Kuala Lumpur, the capital city of Malaysia, has been entangled in the modality of World Class City building. Following key insights by critical scholars like Henri Lefebvre and Doreen Massey, in this article the author shows how spatio-temporal processes have historically produced variegated and contested relational spaces in the city centre. In particular, through the case-study of the recent spatial cleansing of the homeless and soup kitchens in downtown Kuala Lumpur, the author argues for not only critically appreciating the durability and mutability of hegemonic relational spaces but also their potential for irruption because of the ethical dynamic of ‘thrown-togetherness’ that these spaces churn up.

Research Question: This analysis arises from the decision of the current local council of Barcelona regarding the postponement of the sporting mega-event ‘World Roller Games’, due to a lack of a social and sportive implication in this event. This research tries to shed some light on the matter and give evidence to the local council to become the world capital of skating. The research question is to analyse whether non-economic impacts could be relevant enough to organise a mega-event.Research Methods: The methodology is based on the perception and experience of spectators and participants on four main impacts (social, economic, sports city image and sports practice) using a survey from a National Roller Skating Championship in Spain, considering that this profile of respondents have a better knowledge of the current situation of this sport.Results and Findings: There are positive expected future consequences of this mega-event to be held in Barcelona in social and sportive terms. We can also conclude that the local council must still introduce some social and sportive policies in the city in order to improve the chances of success in social, sports practice and sportive brand image development.Implications: It is demonstrated that a mega-event should not be seen purely from a perspective of business generation, especially with minority sports like roller skating. There is a clear opportunity to develop social and sportive practice initiatives that can push social cohesion throughout the city thanks to a mega-event such as this one.

The pandemic of coronavirus disease (COVID-19) led to the need for drastic control measures around the world to reduce the impact on the health of the population. The confinement of people in their homes resulted in a significant reduction in human activity at every level (economic, social, industrial, etc.), which was reflected in a decrease in environmental pollution levels. Studying the evolution of parameters, such as the level of environmental noise caused by vehicle traffic in urban environments, makes it possible to assess the impact of this type of measure. This paper presents a case study of the acoustic situation in Cáceres (Spain) during the restriction period by means of long-term acoustic measurements at various points of the city.

Purpose: Nowadays, the development of technology is very fast and increasingly sophisticated; no doubt all the problems in a city can be solved quickly and well. Hence, facing a huge number of the urban population, the city must adopt the strategy of smart city so that the standard of life can be improved. Some of the cities in the world have applied the concept of smart city. One of the dimensions in smart city concept is smart security and safety. This study aims to know the indicators and index level of smart security and safety in Bandung city of Indonesia. This research explores the indicators and measures the index level of smart security and safety in Bandung.  Methodology: The research method characteristics applied in this study is the exploratory sequential mixed method. Main Findings: This study finds that there are 20 indicators to measure the index level of smart security and safety. The smart security and safety level of Bandung city is 72% which is considered that on average the measured indicators are already good enough and satisfied, but there are some indicators that should be improved. The variable that should be improved is variable of Awareness and Understanding which has score of 49%. Implications/Applications: It is suggested by this study that the socialization of smart security and safety program such as Panic Button Application, LAPOR! The website should be more effective through making socialization more targeted and real.

The cities are expanding rapidly all over the world. India has also experienced this phenomenon and has continued the pace of growth. The recent trends in spatial growth of the cities are a new phenomenon in Indian urban landscape. The cities in India are witnessing development with the help of private developers for the last couple of decades. Being private properties these are by nature of exercising control have gates and boundaries. In scholarly literature these are called as Gated Community/Gated Development. Authors have argued them from various perspectives of anthropology, law, management and sociology etc. but very little has been discussed about their planning and morphology. Although, the rise of Gated Development is majorly attributed to the sense of fear and need for security, yet architects and urban designers, and even sociologist stress upon other methods to make the neighbourhoods secured. Hence the security aspects are not made part of the research here. The aspects of how these gated development impacts the perception of neighbourhood by residents is not touched upon. The paper discusses the distinction between the gated and non-gated neighbourhoods and also how residents perceive their neighbourhoods at large. For explaining this phenomenon, three neighbourhoods in the city of Gurugram in Haryana state in India have been identified as case study. These are identified on the basis of different morphological images that are identified. Space syntax and space cognition through sketch mapping is used for the analysis of the three neighbourhoods. The paper suggest that the continuity and connectivity of any spatial configuration is of utmost importance to make neighbourhood environment worthy of living life more socially connected.

Intersections present a big safety problem in traffic since there has been an increased risk of crashes because of conflicts in the flows intersecting. A great number of studies done in the world show that roundabouts are safer than conventional intersections since it has been recorded that after the conversion to roundabouts the number of crashes has been decreasing. The research on applying Empirical Bayes (EB) method has been conducted by using 15 two-lane intersections in the city of Niš (Serbia), which have been converted into large compact two-lane roundabouts during the period of 2005-2013. The results show that the conversion of conventional intersections into roundabouts has positive effect on reducing the number of crashes. For all intersections, the reduction of crashes is estimated at around 76% for all crashes, i.e. 80% for the crashes with injuries. For different groups of intersections the effects are determined separately.

Surabaya, is one of the oldest cities in Indonesia. Since 1612, Surabaya has been a very busy trading center. Kalimas River, which is the river that flowing in the middle of the city of Surabaya, necessarily be a "River of Gold". It is used by traders, as a transport route for carrying goods from central Java to Surabaya. And from Surabaya, these goods are distributed throughout the world. The river management of Kalimas River is very complex. On the other hand, the development of tourism in Surabaya is very encouraging. Then, it is needed to propose a new tourism destination base on the potential of Kalimas River. Because there is no type of water attractions in Surabaya yet, so we need a study that focused on understanding the river lane as an alternative of water attraction in Surabaya. This research will be done in the realm of qualitative research. Based on the research objectives, the type of research that will be applied research so that the results can be much easier to implement. As the summary, it concluded that there are 4 steps to develop the Kalimas River lane as an aternative for water tourism destination in Surabaya, which are improving the quality of its existing condition, developing its potential to serve the purpose of water tourism, achieving the needs and expectations of the citizens of Surabaya on the river lane as an alternative water tourism destination, and finding new icon for Surabaya water tourism.

Indonesia is an archipelago country in which the tourism sector plays a role as an economic locomotive. In 2016, Indonesia joined the World Halal Tourism Award (WHTA) and won 12 awards, three of which were won by West Sumatra. Bukittinggi is the principal city of tourism in West Sumatra. There are many halal hotels and restaurants and 190 mosques available in the city. Unfortunately, the information regarding the mosque locations is still inadequate. For this reason, this research was conducted in order to develop a web-based and mobile-based geographic information system (GIS) for places of worship information (GPWI) to make it easier for Muslim tourists to find mosques, and other tourism objects and facilities. This paper reports on the development of the GPWI. The development of the GPWI employed the waterfall method. The GPWI allowed tourists to find mosques based on specific criteria, whose output showed them the location, information, route, and local transportation available to get to the mosques as well as other tourism objects and facilities around the mosque. The GPWI was developed using Free Open Source Software (FOSS) PostgreSQL/PostGIS, PHP, JavaScript, and Basic4Android. The spatial-based database and programs that were used to develop this GPWI are the main contributions of this study. Based on the product evaluation, the GPWI successfully met the needs of Muslim tourists in finding mosques during their visits to Bukittinggi.

There is scarcely a district in the world endowed with such singular beauty, and possessing such deep points of interest, as that extending about ten or twelve miles westward from Naples. A sky of such brilliancy as only Italy can shew; a sea of colours like the transparent hues of the sapphire and emerald; mountains on land and mountainous islands rising from the sea twice and thrice the height of those in Wales, and crowned with snow for a third of the year. The air of extraordinary clearness and purity, and redolent with the odours of the myrtle, orange, and citron. The earth covered with rich crops of maize, the vine hanging in a cordage of festoons from tree to tree, huge groves of figs and olives twisted in every fantastic form, and interspersed with the feathery palm, forests of pine, leccio, and cypress, all form a scene of beauty difficult to describe. But how is the interest heightened when we reflect on the history of the spot! We are in the scene so exquisitely described by Virgil in the Æneid. Here are the Isles of the Sirens and of Circe, the Tomb of Misenus, the Grotto of the Sibyl, the mysterious River Cocytus, the Lake Avernus, and the Elysian Fields. Here, too, the great poet is supposed to have been interred. The heights are crowned with the remains of sumptuous villas, where Caesar, Crassus, Pompey, Lucullus, and Augustus feasted, and where Cicero penned his best philosophical works.
