In recent years, walkability is increasingly integrated into sustainability strategies, considering its many health and environmental benefits. Besides, thermal comfort also has been progressively promoted as a critical measure for pedestrian comfort and wellbeing. Despite the relevance of the two concepts, few studies combined them in a comprehensive model. This study considers thermal comfort in assessing walkability by developing a new measurement tool, the Street Walkability and Thermal Comfort Index (SWTCI), which focuses on comfort facilities and Physiological Equivalent Temperature (PET), at the street scale. The applied point system method requires combining a questionnaire survey, observations, and in situ measurements (air temperature, wind velocity, and relative humidity). The questionnaire survey (330 responders) measured 21 street design indicators' importance, using a five-point Likert scale ranging from 1 (least important) to 5 (very important). The observation technique seeks to evaluate every pedestrian comfort indicator score (Sis). The in situ measurements permit Envi-met's calibrated data validation and getting the mean radian temperature (Tmrt). Those were considered in the PET's calculation using Rayman software. Three distinct streets have been chosen in Annaba city, Algeria, within the Mediterranean climate (Csa). The results show that the SWTCI achieves its highest score on the three streets when the thermal perception is neutral (20 < PET <26), and its lowest score, with a warm thermal sensation (28 < PET < 31). Despite the divergence in PET values, the highest score of SWTCI was 33%, reflecting a low comfort quality and minimal pedestrian facilities. Applying the SWTCI method can transform uncomfortable streets into an ideal walkable and pleasant path by finding the problems and proposing improvements.

Studies on inequalities in exposure to flood risk have explored whether population of a lower socio-economic status are more exposed to flood hazard. While evidence exist for coastal flooding, little is known on inequalities for riverine floods. This paper addresses two issues: (1) is the weakest population, in socio-economic terms, more exposed to flood hazard, considering different levels of exposure to hazard? (2) Is the exposure to flood risk homogeneous across the territory, considering different scales of analysis? An analysis of the exposure of inhabitants of Liège province to flood risk was conducted at different scales (province, districts, and municipalities), considering three levels of exposure to flood hazard (level 1- low hazard, level 3- high hazard), and five socio-economic classes (class 1-poorest, class 5-wealthiest households). Our analysis confirms that weaker populations (classes 2 and 3) are usually more exposed to flood hazards than the wealthiest (classes 4 and 5). Still it should be stressed that the most precarious households (class 1) are less exposed than low to medium-range ones (classes 2 and 3). Further on the relation between socio-economic status and exposure to flood hazard varies along the spatial scale considered. At the district level, it appears that classes 4 and 5 are most exposed to flood risk in some peripheral areas. In municipalities located around the center of the city, differences of exposure to risk are not significant.

Oases settlements are common entities of human agglomerations throughout desert regions. Oases settlements face several environmental challenges such as climate change, which can render them insufferably hot and unlivable within decades. Therefore, this study aims to assess the outdoor thermal comfort variation within three different oases urban fabrics of Tolga Oases Complex in Algeria. The overarching aim is to quantify thermal comfort and guide landscape, and urban designers improve outdoor thermal comfort. The methodology relies on microclimatic measurements and weather datasets (TMY2, TMY3, TMYx), combining observations and numerical simulations. A total of 648 Physiological Equivalent Temperature (PET) values were calculated in three different urban fabrics in Tolga Oases Complex, Algeria. Between 2003 and 2017, a remarkable microclimatic change was found, causing a high and accelerated heat stress level of 76%. The study results inform architects, urban planners and climatologists about climate change effects and urban sprawl impact on the oases lands. Moreover, urban strategies should seek mitigation and adaptation benefiting from the existing green infrastructure of palm groves.

This paper addresses the governance of the ‘live-work mix’. This concept refers to the renewed intertwining of living and working activities in new housing and urban development in the context of welfare state restructuring, development of the knowledge economy and globalisation. Implementing live-work goals can be difficult because a consensus between public and private actors is usually needed to develop such projects. In this paper, we examine the actors and instruments that assist in the implementation of live-work goals in targeted areas. We survey live-work development by analysing three illustrative projects in Brussels and Amsterdam, cities with comparable strategies but distinct planning systems. Our results indicate that state support is essential to enhance live-work mix, especially because the market remains reluctant to mix functions and focuses primarily on housing development. Flexible and tailor-made instruments are used, sometimes co-authored by public and private actors, to reach consensus. These instruments illustrate variants of strategic planning. Despite a shared interest in attracting target groups to redevelopment areas, the consensus-building process is affected by discrepancies in the nature of live-work mix.

Flooding is currently one of the major threats to cities in Sub-Saharan Africa (SSA). The demographic change caused by the high rate of natural increase, combined with the migration toward cities, leads to a strong demand for housing and promotes urbanization. Given the insufficiency or absence of adequate planning, many constructions are installed in flood-prone zones, often without adequate infrastructure, especially drainage systems. This makes them very vulnerable. Our research consists of carrying out a spatiotemporal analysis of the agglomeration of Antananarivo (Madagascar). It shows that urbanization leads to increased exposure of populations and constructions to floods. There is a pressure on land in flood-prone zones due to the exponential growth of the population at the agglomeration level. Some 32% of the population of the Antananarivo agglomeration lived in flood-prone zones in 2018. An analysis of the evolution of built spaces from 1953 to 2017 highlights that urban expansion was intense over those years (6.1% yearly increase of built areas). This expansion triggered the construction of built areas in flood-prone zones, which evolved from 399 ha in 1953 to 3675 ha in 2017. In 2017, 23% of the buildings in the agglomeration, i.e., almost one out of every four buildings, were in flood-prone zones. A share of the urban expansion in flood-prone zones is related to informal developments that gather highly vulnerable groups with very little in terms of economic resources. Better integration of flood risk management in spatial planning policies thus appears to be an essential step to guide decisions so as to coordinate the development of urban areas and drainage networks in a sustainable way, considering the vulnerability of the population living in the most exposed areas.

Andean cities are increasingly subjected to landslide susceptibility and events, accompanied by population and urban growth and uncertain extreme climate events. In light of this, academic and professional communities have begun to pay close attention and now face the challenge of producing more detailed knowledge and converting it into effective action. This article is based on a literature review supporting a multidimensional conceptual framework to address landslide risk reduction for the urban Andes context. It aims to complement the environmental dimension, which often shows the resulting physical condition of risk, with landslide risk root-causes by exploring socio-economic and socio-cultural dimensions and the policy and institutional apparatuses that accompany the former dimensions. We aim to identify and understand the inextricable links between the four dimensions and determine how subdimensions can operatively describe and help to understand this complexity. An example from a landslide risk-prone site in Quito illustrates the application of the framework and delivers lessons from a specific context and time. Parts of these lessons may be common for other contexts, but their understanding is critical for landslide risk reduction.

The distribution of urban ecosystem services (UES) is often uneven across socioeconomic groups, leading to environmental justice issues. Understanding the distribution of UES across a landscape can help managers ensure an equitable distribution of services. While many past studies have focused on the distribution of green spaces in relation to socioeconomic variables, this research analyzes the distribution of UES provided by these green spaces. This research quantified air pollution removal, atmospheric carbon reduction, and surface runoff mitigation provided by urban trees in Strasbourg city (France). The provision of these three UES was studied at the census block scale by creating an index of UES delivery, which was contrasted with a constructed social deprivation index. Our results show that there is no significant association between the delivery of UES and social deprivation. Some deprived populations benefit from high UES delivery. Results also suggest that mapping associations between UES delivery and social deprivation should be integrated with future development plans to enhance the equitable distribution of UES. This study provides insights into the French context where studies about the distribution of UES at a small-area level remain lacking.

Understanding how, where, and when a city is expanding can inform better ways to make our cities more resilient, sustainable, and equitable. This paper explores urban volumetry using the Building 3D Density Index (B3DI) in 2001, 2010, 2019, and quantifies changes in the volume of buildings and urban expansion in Luxembourg City over the last two decades. For this purpose, we use airborne laser scanning (ALS) point cloud (2019) and geographic object-based image analysis (GEOBIA) of aerial orthophotos (2001, 2010) to extract 3D models, footprints of buildings and calculate the volume of individual buildings and B3DI in the frame of a 100 × 100 m grid, at the level of parcels, districts, and city scale. Findings indicate that the B3DI has notably increased in the past 20 years from 0.77 m3/m2 (2001) to 0.9 m3/m2 (2010) to 1.09 m3/m2 (2019). Further, the increase in the volume of buildings between 2001–2019 was +16 million m3. The general trend of changes in the cubic capacity of buildings per resident shows a decrease from 522 m3/resident in 2001, to 460 m3/resident in 2019, which, with the simultaneous appearance of new buildings and fast population growth, represents the dynamic development of the city.

The COVID-19 pandemic has led to many countries closing their borders, and numerous people spending their holidays at home instead of traveling abroad. This sudden reduction in travel activities, and other ‘new normals’, might have influenced people’s water usage. Hence, using Liège as a case study, this study aims to address the potential effect of outbound tourism on water consumption and how the current situation might affect the total water demand. Statistical models were developed and validated using the total daily volume of 23 municipalities in the Liège conurbation, the monthly total number of outbound trips, and other meteorological data. Results suggest significantly lower water demand in the months with high numbers of outbound travel activities. Though the projected risk of increased water needs due to fewer people traveling is moderate, the threat becomes much higher during long periods of dry and hot weather.

Urban sprawl is widely acknowledged as an environmental and socio-economic challenge worldwide. This study examines urban sprawl in Belgium over six decades from 1950 to 2010. We assume that sprawl is a self-reinforcing process, i.e., sprawl is fueling further sprawl over time. The main objective of this study is to examine this assumption. We measure urban sprawl at four different levels in this study: country, regions, municipalities, and 1-km2 cells. Three sprawl indices are employed: the degree of urban dispersion, degree of urban permeation of the landscape, and built-up land uptake per capita. These three indices consider both the growth of built-up areas and population density to measure the magnitude of sprawl. The drivers of urban sprawl have been analyzed at a 1-km2 level. The examined drivers are previous urban dispersion patterns, distance to urban cores, elevation, and slope degree by means of linear regression. Urban sprawl significantly increased between 1950 and 1980, whereas its increase was more moderate between 1980 and 2010. Urban dispersion and permeation strongly affect the Brussels and Flanders regions. The results show that the increase in the degree of dispersion is locally driven by previous values of dispersion; i.e., it provides an adequate milieu for further dispersion. Therefore, our conclusion is that urban sprawl in Belgium tends to be a self-reinforcing process.

This paper presents a systematic analysis of the influence of nine urban characteristics (distance between buildings, mean building size, building coverage, etc.) on surface flow in case of pluvial flooding. Time dependent stored volumes, outflow discharges and mean water depths were computed for a set of 2000 synthetic urban forms, considering various terrain slopes and return periods of the rainfall. An efficient porosity-based surface flow model was used to compute the 2D flow variables. Statistical analysis of the relationship between the flow and urban variables highlights that the flooding severity is mostly influenced by the building coverage.

Co-production of water and sanitation services has become a widely discussed option for equitable and efficient service delivery, especially for cities of the Global South. Theoretical conceptualizations of service co-production mainly refer to the public management and governance dimension, while the techno-environmental and spatial dimensions are often disregarded in the literature. This article proposes a comprehensive framework for analyzing water and sanitation co-production based on cross-cutting literature, from public service management/governance to urban, socio-ecological and socio-technical fields. The proposed framework highlights the categories and factors to be considered when analyzing the background conditions and outcomes of unorthodox service delivery.

This study focuses on the role of controversies in heritage management, considering more specifically cities characterized by tensions between community groups. In such cities, the regulatory and institutional systems are challenged by highly structured community-based initiatives and organizations. Using an analytical framework that assesses the regulatory system, urban conservation, and development practices, we compared two heritage management projects in Tripoli (Lebanon). Our results highlight the dichotomy between decision makers' and communities’ approaches to the definition and management of heritage and to the struggle over the use of public spaces to reclaim heritage values. The discussion highlights how controversies emerge from the physical assets that are claimed as heritage, the range of values associated with tangible assets, and how local communities may coproduce heritage knowledge and actively contribute to the democratization of heritage values.

This paper presents the implementation of a tool that can be used to characterise chromatic attributes of an urban area. The challenge is to provide statistical and quantitative answers to these questions: how is colour organised, how does it develop its own structure in the city? How can colour appear as an indicator of homogeneity and spatial coherence? We use a K-means statistical clustering technique to produce chromatic types of building façades. Once the chromatic categories are defined, the question of spatial coherence is investigated using the Shannon entropy value as an indicator. Our method was tested through an application to 18 urban fragments of the city of Liège (Belgium). The research highlights the differences between compact urban areas (historic centre, nineteenth century developments) and new urban configurations (city entrances, commercial and peri-urban zones).

The literature on Smart Cities lacks of research on how actors understand and appropriate the Smart City. This paper questions in an innovative way their appropriations of the phenomenon. Smart City is considered as an instrument, following the theory of Lascoumes and Le Galès (2007). Is the Smart City a functional instrument: a kind of evidence and a pragmatic solution at disposal or a public policy instrument: not neutral, provoking debates and influencing policies? An empirical analysis is carried on based on a survey among 193 Belgian actors active in the domain. The results show that the Instrument theory is relevant to analyse the actors' appropriation, which do not follow a homogeneous trend. In fact, each actor follows his own logics which will be interesting to study.

In 2011, UNESCO adopted the Historic Urban Landscape (HUL) recommendation and called for the application of a landscape approach to ensure the integration of cultural heritage policies and management concerns in the wider goals of sustainable urban development. This paper tracks the genesis of a landscape approach to heritage conservation, and then presents a systematic review of the literature on the HUL. More than 100 publications from 2010 to early 2018 were analysed. The applied methodology combined an inductive categorization method with a deductive data mining method. The objective is to determine whether the academic discussion is addressing the different dimensions of the HUL approach, including the holistic, integrated, and value-based dimensions, and whether it is progressing through time to move from a conceptual to an operational level. Results show that while the discussion is heavily focused on values, the operationalization of a value-based approach is still lacking, as it is not fully contextualized in relation to local heritage discourses and the dynamics of heritage governance. Results also show that many case studies applications are in ‘non-Western’ cities, thus opening the debate about the accountability of a value-based approach in contexts that tend to be dominated by groups with the most political power, and where conservation practices mainly focus on the mobilization of material heritage to foster its economic value. Nevertheless, the transition from international guidelines to contextualized local endeavours and policies remains a challenge to be solved.

Land change (LC) models are dedicated to a better understanding of land use and land cover dynamics. A fundamental aspect of those models lies in the calibration of spatial parameters underlying such dynamics. Although there are many studies on the calibration of LC models, current efforts have a common goal of seeking to find a single global optimum solution, even though land change dynamics may be inherently heterogeneous throughout a given space. This article presents a calibration approach for finding multiple optimal solutions. A crowding niching genetic algorithm (CNGA) is incorporated into a cellular automata LC model. The model is applied to simulate urban expansion in Wallonia (Belgium) as a case study. Our findings demonstrate the ability of the model to locate multiple solutions simultaneously. In addition, the CNGA performs better than the standard genetic algorithm—besides, the CNGA helps to better understand the properties of land change dynamics within a given landscape.
