ObjectiveCountries in sub-Saharan Africa suffer the highest rates of child mortality worldwide. Urban areas tend to have lower mortality than rural areas, but these comparisons likely mask large within-city inequalities. We aimed to estimate rates of under-five mortality (U5M) at the neighbourhood level for Ghana’s Greater Accra Metropolitan Area (GAMA) and measure the extent of intraurban inequalities.MethodsWe accessed data on >700 000 women aged 25–49 years living in GAMA using the most recent Ghana census (2010). We summarised counts of child births and deaths by five-year age group of women and neighbourhood (n=406) and applied indirect demographic methods to convert the summaries to yearly probabilities of death before age five years. We fitted a Bayesian spatiotemporal model to the neighbourhood U5M probabilities to obtain estimates for the year 2010 and examined their correlations with indicators of neighbourhood living and socioeconomic conditions.ResultsU5M varied almost five-fold across neighbourhoods in GAMA in 2010, ranging from 28 (95% credible interval (CrI) 8 to 63) to 138 (95% CrI 111 to 167) deaths per 1000 live births. U5M was highest in neighbourhoods of the central urban core and industrial areas, with an average of 95 deaths per 1000 live births across these neighbourhoods. Peri-urban neighbourhoods performed better, on average, but rates varied more across neighbourhoods compared with neighbourhoods in the central urban areas. U5M was negatively correlated with multiple indicators of improved living and socioeconomic conditions among peri-urban neighbourhoods. Among urban neighbourhoods, correlations with these factors were weaker or, in some cases, reversed, including with median household consumption and women’s schooling.ConclusionReducing child mortality in high-burden urban neighbourhoods in GAMA, where a substantial portion of the urban population resides, should be prioritised as part of continued efforts to meet the Sustainable Development Goal national target of less than 25 deaths per 1000 live births.

there are limitations in understanding this concept in the Malaysian context. This research examines the relationship of liveability between people and place in their daily lives, to explore comprehensively liveability in urban neighbourhoods through residents' perceptions and the perceived degree of liveability. Qualitative and quantitative data collected in 5 urban neighbourhoods in Iskandar Malaysia suggests that liveability must correspond to residents' requirements for good quality facilities and services, good neighbourhood conditions and positive community engagement.

For developing countries, garbage classification has become an important measure to handle the environmental pollution crisis. This empirical study examined urban and rural families’ willingness to sort and deposit garbage at fixed recycling points. We found that urban residents demonstrated a significantly higher willingness to sort and deposit garbage at designated points compared to rural residents. The average number of family meals per month, average monthly household food expenditure, household cleanliness, and household crowding (spaciousness) are significantly related to a family’s willingness to sort garbage. In terms of neighbourhood factors, families living in neighbourhoods with property management are more likely to have a higher willingness to sort garbage. The degree of air pollution in the neighbourhood also has an impact on the family’s willingness to sort garbage. This study proposes that neighbourhood factors have a non-negligible influence on a household’s willingness to sort and put garbage in designated locations. Especially in urban neighbourhoods, the willingness of residents living in commodity housing neighbourhoods to sort and place garbage at designated locations is significantly higher than that of residents living in other neighbourhoods. To improve the implementation effect of the waste sorting policy, we suggest that the configuration of neighbourhood garbage recycling services and facilities should be improved so that people can sort garbage more conveniently.

While the commons and commoning are generally associated with community-based ecosystems at the localised scale of the neighbourhood, ambitious reinterpretations explore possibilities for scaling up commoning as a collaborative and sustainable form of urban governance engaging multiple stakeholders through the quintuple helix. Inspired by the City as Commons approach first imagined and formulated in Bologna, Italy, this paper presents original findings from a transdisciplinary action research project for studying and cultivating commoning-as-governance in a politically disaffected and economically marginalised inner-city neighbourhood in Liverpool, England. It examines the social relations (re)constituting an urban ecosystem for commoning and asks how such initiatives for designing collaborative programmes for transforming urban environments through public-common partnerships might work in contexts in which the material and affective resources for commoning have been exhausted by post-democratic privatisation and neoliberal austerity. Drawing on theories of radical democracy and post-politics, the City as Commons approach is critically evaluated and argued to be insufficient to the challenging task of engendering commoning in the disintegrating urban neighbourhoods that would arguably benefit most from such activities. The paper tells the story of how this transdisciplinary project ultimately failed in its aims and, through engagement with recent interventions on the politics of failure in the neoliberal university, reflects on the implications for future action research on commoning.

The continuous urbanisation in most Low-to-Middle-Income-Country (LMIC) cities is accompanied by rapid socio-economic changes in urban and peri-urban areas. Urban transformation processes, such as gentrification as well as the increase in poor urban neighbourhoods (e.g., slums) produce new urban patterns. The intersection of very rapid socio-economic and demographic dynamics are often insufficiently understood, and relevant data for understanding them are commonly unavailable, dated, or too coarse (resolution). Traditional survey-based methods (e.g., census) are carried out at low temporal granularity and do not allow for frequent updates of large urban areas. Researchers and policymakers typically work with very dated data, which do not reflect on-the-ground realities and data aggregation hide socio-economic disparities. Therefore, the potential of Earth Observations (EO) needs to be unlocked. EO data have the ability to provide information at detailed spatial and temporal scales so as to support monitoring transformations. In this paper, we showcase how recent innovations in EO and Artificial Intelligence (AI) can provide relevant, rapid information about socio-economic conditions, and in particular on poor urban neighbourhoods, when large scale and/or multi-temporal data are required, e.g., to support Sustainable Development Goals (SDG) monitoring. We provide solutions to key challenges, including the provision of multi-scale data, the reduction in data costs, and the mapping of socio-economic conditions. These innovations fill data gaps for the production of statistical information, addressing the problems of access to field-based data under COVID-19.

Abstract It is well-known that the morphology of urban areas modifies the variations of climate variables at microscale; known as microclimate conditions. The complexity of urban morphology can lead to undesired wind conditions or excessive air temperature; particularly in extreme weather conditions. This study attempts to quantify the impacts of urban morphology on the evolution of wind speed and air temperature at the urban canopy layer using Computational Fluid Dynamic (CFD) simulations. In this regard, three urban neighbourhoods are generated based on a novel urban morphology parameterization method and assessed in two extreme low and high wind conditions. Results showed that wind speed (up to 75%) and air temperature (up to 28%) at the microscale can get amplified or dampened in extreme conditions. A negative correlation was observed between wind speed and air temperature variations indicating a great potential to reduce outdoor air temperature through heat removal in urban canyons. The findings of the study are categorized based on the morphological parameters to present a series of design-based strategies for the newly-built urban neighbourhoods.

Abstract To prevent undercooling of the ground in densely populated areas, regeneration of borehole heat exchangers (BHEs), for example by solar thermal heat, may become necessary. However, the usable roof area is often small compared to the building’s heat demand, especially in urban areas. It was investigated how much regeneration is possible in districts that are supplied entirely by heat pumps with BHEs. Example buildings were modelled based on the buildings of two districts in Zurich. Uncovered PVT collectors and glazed flat-plate collectors were used as regeneration sources. The possible regeneration was determined in a simulation process that included the effects of mutual influences between the BHEs of neighbouring buildings. As expected, glazed flat-plate collectors allow for more regeneration than uncovered PVT collectors. For full regeneration, the required usable roof area relative to the annual heat demand is about 1.8m2/MWh for PVT and 1.2m2/MWh for flat-plate collectors. Large buildings often do not provide sufficient roof area for full regeneration. A sustainable heat supply of the entire district with regenerated BHEs can be possible in suburban neighbourhoods, if the bigger buildings are distributed rather evenly. In urban neighbourhoods, areas may exist in which solar thermal regeneration alone is not sufficient.

Purpose What makes neighbourhood environment more walkable is an important question for urban planning and design research. The purpose of this paper is to explore this question through a case study of urban sidewalks in different contexts of urban neighbourhoods in Rajshahi city of Bangladesh. Design/methodology/approach Using participatory observation, Google street view and photography techniques, it examines the quality of the street facilities by demonstrating physical attributes of sidewalks and by analysing how various obstructions on them characterize neighbourhood walkability environment. Findings The findings suggest that the unusable sidewalks in Rajshahi city, Bangladesh, are a production of inadequate and inappropriate planning and design that unable to capitalize the functionality of sidewalks as a means of walking. It further argues that the urban planners and designers of streets have paid little attention to the diverse requirements of sidewalks in accordance with spatial and socio-economic categories of urban neighbourhoods. Originality/value This study adds insights about the urban sidewalks planning and design in the context of a developing country. It provides an empirical evidence about the constraints and potentials of making a walkable city.
