Sub-Saharan Africa's rapid urban growth is causing a decline in urban agricultural land, reducing access to healthy local food for citizens. This paper quantitatively and spatially describes the contribution of urban and peri-urban producers to the availability and accessibility of fresh leafy vegetables in the growing city of Dar es Salaam, Tanzania. Based on over 700 surveys with food vendors and consumers, as well as ethnographic research with farmers, we show how a total of 70 per cent of all amaranth consumed in Dar es Salaam was found to be produced within the city. With an average distance travelled from farm to fork of 11 km, leafy vegetables have a strongly localised foodshed. The results show the ongoing significance of urban areas in meeting their own food demands, emphasising the necessity to explicitly integrate food provisioning in the planning of growing African cities.

Pollinator diversity and abundance are under direct threat from human activities. Despite societal dependence on pollinators for crop production, humankind continues to drive pollinator declines through agricultural intensification and urbanisation. Urban environments can provide refuge to some pollinators. There is a need, however, to understand how pollinator communities can be supported in these areas while also considering human needs. Public green spaces provide a promising avenue to target plant–pollinator conservation measures in an urban setting due to their large area, high abundance and low plant–pollinator biodiversity. We used a paired design to compare the plant community, pollinator community and plant–pollinator interactions of (i) public urban green spaces enhanced with wildflower meadows and pollinator‐friendly ornamental plantings to (ii) control unenhanced urban green spaces. The planting types within enhanced sites were also separately compared. Our results show that not only was the diversity of the overall pollinator community higher in enhanced than control sites, but also the complexity of some wild Hymenoptera and the abundance of Diptera pollinator groups. The negative impact of urbanisation on some pollinator groups was reduced in enhanced sites compared with control sites. Planting both pollinator‐friendly ornamental plants and wildflower meadows significantly increased the visits from Diptera and the diversity in the plant–pollinator community compared with wildflower plantings alone. Our results suggest that enhancing public spaces for pollinators has positive effects on key groups and can help mitigate the impacts of urbanisation. Non‐native ornamental plants can also play a role in enhancing green spaces for pollinators while maintaining their recreational functions. This supports a mixed‐planting approach for improving public green spaces in urban areas for both people and nature. [ABSTRACT FROM AUTHOR]

AbstractMany coastal small-scale fishing (SSF) communities in low and middle-income countries are experiencing urbanisation due to global development and migration patterns. Scholars have documented how processes related to urbanisation present SSF communities with a unique series of opportunities and challenges. However, it is still poorly understood how SSF communities perceive and pursue resilience while adapting to these changing conditions. To address this gap, we conduct ethnographic research among the members of a fishing cooperative in Cancun, Mexico. We find that four factors related to Cancun’s pattern of development have incentivized local fishers to adopt a trans-sector perspective of livelihood resilience through which they view fishing as a lucrative but fleeting opportunity, with some actively planning a transition to non-fishing livelihoods. These four factors are the depletion of local fisheries, rising land values, the proliferation of non-fishing livelihood opportunities, and regional migration patterns. Whether local fishers ultimately prove resilient to the stresses of urbanisation depends partly upon the degree to which local governance and support systems align with this perspective. By contextualizing these findings within the broader literature on SSFs and urban development, we develop a heuristic to hypothesize to what extent these findings are generalizable beyond the study context.

Urbanisation has been increasing worldwide in recent decades, driving environmental change and exerting novel selective pressures on wildlife. Phenotypic differences between urban and rural individuals have been widely documented in several taxa. However, the extent to which urbanisation impacts mating strategies is less known. Here, we investigated extra‐pair paternity variation in great tits (Parus major) and blue tits (Cyanistes caeruleus) breeding in nestboxes set in a gradient of urbanisation in Warsaw, Poland, over three breeding seasons. Urbanisation was quantified as the amount of light pollution, noise pollution, impervious surface area (ISA) and tree cover within a 100‐m radius around each nestbox. We obtained genotypes for 1213 great tits at 7344 SNP markers and for 1299 blue tits at 9366 SNP markers with a genotyping‐by‐sequencing method, and inferred extra‐pair paternity by computing a genomewide relatedness matrix. We report higher extra‐pair paternity in blue tits breeding in more urbanised areas, for example, with higher light pollution and ISA, and lower tree cover. However, no such trend was found in great tits. Late‐stage survival of individual nestlings in both species was not associated with paternity or urbanisation proxies, thus we were not able to detect fitness benefits or drawbacks of being an extra‐pair offspring in relation to urbanisation. Our results contribute to the growing body of knowledge reporting on the effects of urbanisation on avian ecology and behaviour, and confirm species‐specific and population‐specific patterns of extra‐pair paternity variation.

The recognition of low-density urbanisation has been important in documenting how diverse human settlements generated enduring social and economic change. In tropical regions, the key challenges to studying low-density urbanisation have been the difficulty in acquiring past built environment data and integrating the frameworks that illuminate the social behaviours intrinsic to urbanisation. The introduction of lidar mapping and urban science methods has proven revolutionary in our understanding of low-density urbanisation as demonstrated by emerging research on settlements and states in Mesoamerica and Southeast Asia. These studies draw on urban theory to highlight patterns in the built environment associated with profound societal changes including the rise of social institutions, agglomeration effects, and ongoing settlement growth. Here, we present an approach that combines lidar survey and archaeological fieldwork with recent developments in urban science to understand the built environment of Tongatapu; the location of an archaic state whose influence spread across the southwest Pacific Ocean between the thirteenth and nineteenth centuries a.d. Quantitative results show—for the first time—that settlements on a Pacific island were urbanised in a distinct low-density form and that the processes of urbanisation began prior to state development. This study highlights the potential contribution of Pacific landscapes to urban science and the low-density settlement phenomena given the presence of large populations, hierarchical societies, and vast distributions of archaeological built remains on many island groups.

This article explores multilevel governance networking and innovation to better understand how nature-based public health can be promoted at a grassroot level within an urban context. Hence, the leading research question examines the extent of networking and collaboration within state and municipal policymaking and the implementation of socially inclusive nature-based activities among urban youths conducted by local volunteer organisations. Multilevel networking and collaboration represent an analytical alternative to bottom-up and top-down strategies, which dominate the socio-political policies of outdoor studies in several countries. The exploration draws on empirical research conducted in 2020 based on a qualitative design. A website review was carried out to analyse facilitated nature-based health innovations embracing educational activities, leadership, and organisation run by local volunteer organisations targeting youth aged 6–19 across Oslo, Norway's capital. The investigation was substantiated by twenty-eight interviews with leaders of volunteer organisations and primary healthcare coordinators in five of Oslo's fifteen city districts, exploring their organisational experiences and reflections on nature-based innovations as a measure to promote health. The governance approach revealed several paradoxes and ambiguities in policy and practice. For example, there is a gap between the policy vision and available resources. There is also a need to understand better the complex networks and collaboration of public agencies and dedicated volunteers, their organisations, and interests. Furthermore, the continuous professionalisation of the voluntary sector and its significance in building a governance infrastructure that increases the capability of ongoing nature-based activity innovations need to be developed to meet policy goals and young people's needs and interests. Social inequalities were reported among those participating in nature-based activities and those who were not engaged. This pattern follows the well-documented spatial distribution of socioeconomic disparities. [ABSTRACT FROM AUTHOR]

Urban environments present novel ecological challenges to wild species. In birds, urban populations generally exhibit reduced clutch sizes compared to forest populations. However, whether smaller urban clutches are adaptive or a result of environmental constraints is unclear. To investigate these two hypotheses, we quantified the ability of urban and non‐urban blue tits (Cyanistes caeruleus) to lay new eggs after an experimental manipulation aimed to increase egg production. We removed the first four eggs laid by urban and forest birds to test their ability to produce new eggs. If the urban environment imposes constraints on egg production, we predicted that urban birds would not lay new eggs. If the small clutches of urban birds are an adaptive response, we predicted they would lay new eggs to reach the optimal clutch size for the environment. Consistent with the environmental constraint hypothesis, our results suggest that urban females do not lay new eggs to the same extent as forest birds following egg removal. Forest birds laid approximately two new eggs after our experimental manipulation, while urban birds laid approximately 0.36 new eggs following egg removal. Our manipulation resulted in a brood reduction in the urban experimental nests, yet there was no difference in the number of fledged offspring between urban control and experimental nests. This suggests that females might be misjudging urban habitat quality and produce a clutch with more eggs than nestlings they can rear. Overall, our results suggest that environmental constraints could limit the number of eggs that urban females lay, generating urban versus non‐urban differences in this trait. [ABSTRACT FROM AUTHOR]

Intensification of agricultural production to support demographic growth has been invoked as a necessary correlate to the important socio-economic changes involved in the urbanisation process of Western Central Italy at the beginning of the 1st millennium BCE. Yet, the agricultural economy of the early urban centres in the region remains poorly understood. Ongoing excavations at Gabii provide a new substantial archaeobotanical dataset that allows the investigation of crop production and farming practices during the transitional period between the eighth and the sixth century BCE. This study presents a multi-proxy approach that integrates archaeobotanical data with carbon and nitrogen stable isotope analyses on charred cereal grains to reconstruct Gabii's crop husbandry regimes. Our results show an unexpected local combination of staples in which barley is the most common crop. No significant changes are visible throughout the period suggesting a remarkable consistency in crop selection and persistence of traditional practices. The stable nitrogen isotope analysis has revealed low values that we argue could be an indication of intercropping cereals and pulses. A drop in the water availability during the sixth century BCE could be related to a combination of environmental factors, human behaviours, and, possibly, production stress. [ABSTRACT FROM AUTHOR]

Urban areas can be both detrimental for pollinators or function as suitable habitats, depending on the land-use type, the urban context and the pollinator group in focus. Urban green spaces, including gardens, parks or cemeteries can provide essential resources for a wide range of pollinator groups, like wild bees, hoverflies and beetles. Urban community gardens can be particularly structurally complex and harbour a diverse range of nesting and food resources for pollinators. However, we know little about how garden features may vary with the urban context of gardens and which specific garden features can increase the abundance of pollinators in general and of different pollinator groups. Over two summer seasons, we recorded garden features and pollinators using flower observations in 33 urban community gardens in Munich and Berlin, Germany. We examined how garden features differ amongst urban community gardens from three urbanisation categories, and analysed the effects of garden features such as floral and nesting resources and landscape imperviousness (as indicator of urbanisation) on pollinator abundance, richness and diversity. In more urbanised gardens, flower richness and bare substrate were less prevalent. Flower richness was positively correlated with overall pollinator abundance, richness and diversity as well as with the abundances of all pollinator taxa excluding beetles. Landscape imperviousness was negatively correlated with hoverfly and beetle abundances. Hoverflies also decreased with increasing bare substrate and wasp abundance decreased with increasing deadwood availability. Our findings highlight the important role of flower richness for insect conservation in urban management and show that pollinator taxa react differently to garden features and urbanisation. To support pollinating insects, gardeners can increase flower richness, especially in highly urbanised areas. [Display omitted] [ABSTRACT FROM AUTHOR]

Urbanisation is associated with air and soil pollution, particularly from heavy metals. One of the tissues most exposed to such pollutants is the midgut epithelium as insects may ingest these pollutants with food. Bees are one of the most important urban insects, providing important ecosystem services such as pollination. However, to the best of our knowledge, no studies have investigated the possible histological alterations to the midgut epithelium of bees caused by urbanisation. We sampled workers of the ground-nesting, primitively eusocial bee Halictus scabiosae in a large metropolis (Milan), with the aim to test if individuals from areas characterised by higher urbanisation and consequently higher pollution levels—defined here by a greater proportion of roads—exhibit greater histological tissue and cellular alterations in the midgut epithelium. We obtained semi-thin sections of the midgut through histological techniques, and then adopted a semi-quantitative approach to assess morphological damage. The midgut presented a range of histological alterations including epithelium disorganisation, vacuolisation, and nucleus karyorrhexis (one of the stages of cellular death). We found higher histological damage score (calculated taking into account all found alterations) and frequency of karyorrhectic nuclei in sites with a higher proportion of roads (i.e. more urbanised). The observed alterations may underline a potential impairment of the digestive function in highly urbanised areas. [ABSTRACT FROM AUTHOR]

This paper examines the importance of Highfield to the African entrepreneurship history of colonial Zimbabwe, then known as Southern Rhodesia. The Southern Rhodesia colonial state established the township of Highfield in its capital city, Salisbury (now Harare), in 1936 as part of its spatial and racial segregation policy. The policy made Africans temporary residents in the urban areas. However, the post-Second World War industrial growth forced the colonial state to revisit its stance on African urbanisation. Seen as critical for the expanding manufacturing sector, African labour now had to be accommodated in the urban areas, which triggered the colonial state to expand the township of Highfield in 1956. That very year, enterprising Africans responded by taking up the expanded township's entrepreneurial opportunities. This response and the subsequent evolution of African entrepreneurship in Highfield township are the focus of this paper. The paper provides a historical kaleidoscope of Highfield as a place of African entrepreneurship, which thus far has been occluded and separated from the dominant literature on the township's role in the rise of African nationalism and anti-colonial struggles. Highfield emerged as a cultural milieu hosting an African Renaissance in food, fashion and lifestyle inspired by a mix of modernity and indigenous ethos. Thus, the paper argues that Highfield was the entrepreneurial centre of various businesses and startups. These colourful stories of African entrepreneurship are gleaned from handwritten business stand applications by African traders, archival documents, and newspapers in piecing together an urban history of African entrepreneurship in the township of Highfield in colonial Zimbabwe.

With the rise of forced displacement, attention has turned to the economic impact of refugees. However, few studies investigate long-term impacts. We use data for Tanzania for the period 1985–2015 to examine the effect of camps on urbanisation and local development, exploiting a unique satellite-derived dataset of high spatial resolution and temporal frequency. We show a modest but significant effect of refugee camps on built-up area up to a 100 km distance. We then match camp locations to regional gross domestic product, local consumption spending and employment patterns. Output in areas with camps grew at a faster rate during camp operation, but closure of camps was associated with change in economic activity. Activity induced by camps is largely in non-tradeable goods and services rather than inducing longer run structural transformation. [ABSTRACT FROM AUTHOR]

Urbanisation is a crucial issue for urban planners and researchers worldwide, especially in South Asia, where rapid urbanisation has led to several negative impacts on the environment, economy, and people. Land-use change is one of the associated problems of urbanisation that can lead to an increased land surface temperature (LST) and surface urban heat island (SUHI) effect. This study aimed to investigate the impact of urbanisation on the local climate in Dehradun city, India, by analysing the relationship between land-use and land-cover (LULC) change, LST, and the UHI effect. Geospatial analyses were carried out using Landsat multispectral data from 1996 to 2019. LULC classification using a machine learning-based supervised classification technique, support vector machine and LST were derived using a mono-window algorithm, and the surface UHI (SUHI) effect was quantified using the urban thermal field variance index (UTFVI). The study found that the built-up cover increased by 28%, resulting in seasonal LST increases of 7 °C and 2 °C for the summer and winter seasons, respectively. The findings show that the regions with no SUHI effect reduced significantly from 42.59% in 1996 to 21.55% in 2019, while the strongest SUHI regions increased from 0% in 1996 to 10.7% in 2019. This study contributes to delivering scientific information on the impact of urbanisation and land-use change on the urban thermal environment of the city, which may be useful for policymakers in developing appropriate strategies to reduce the impact of urbanisation on the environment and to improve the quality of life for citizens.

Background: High rates of labour augmentation with oxytocin have been found in some low- and lower-middle-income countries, causing potential perinatal harm. It is critical to understand the reasons for this overuse. Aim was to explore factors that shape practices around using oxytocin for labour augmentation in a high-volume labour ward in Dar es Salaam, Tanzania. Methods: Mixed-methods data collection was conducted from March 2021 to February 2022, including structured observations of 234 births, 220 h of unstructured labour ward observations and 13 individual in-depth interviews with birth attendants. Thematic network analysis and descriptive statistics were used to analyse data. We used a time-lens to understand practices of oxytocin for labour augmentation in time-pressured labour wards. Results: Birth attendants constantly had to prioritise certain care practices over others in response to time pressure. This led to overuse of oxytocin for augmentation to ensure faster labour progression and decongestion of the, often overburdened, ward. Simultaneously, birth attendants had little time to monitor foetal and maternal condition. Surprisingly, while oxytocin was used in 146 out of 234 (62.4%) structured labour observations, only 9/234 (4.2%) women had active labour lasting more than 12 h. Correspondingly, 21/48 (43.8%) women who were augmented with oxytocin in the first stage of labour had uncomplicated labour progression at the start of augmentation. While the partograph was often not used for decision-making, timing of starting oxytocin often correlated with natural cycles of ward-rounds and shift-turnovers instead of individual women's labour progression. This resulted in co-existence of 'too early' and 'too late' use of oxytocin. Liberal use of oxytocin for labour augmentation was facilitated by an underlying fear of prolonged labour and low alertness of oxytocin-related risks. Conclusions: Time scarcity in the labour ward often made birth attendants deviate from clinical guidelines for labour augmentation with oxytocin. Efforts to navigate time pressure resulted in too many women with uncomplicated labour progression receiving oxytocin with little monitoring of labour. Fear of prolonged labour and low alertness to oxytocin-mediated risks were crucial drivers. These findings call for research into safety and benefits of oxytocin in low-resource settings and interventions to address congestion in labour wards to prevent using oxytocin as a time-management tool.

Urbanisation has reduced the abundance and diversity of many taxonomic groups, and the effects may be more pronounced on islands, which have a smaller regional species pool to compensate. Green spaces within urban environments may help to safeguard wildlife assemblages, and the associated habitat heterogeneity can even increase species diversity. Here, total abundance and species diversity of butterflies, birds, and vegetation at nine rural and nine urban locations were quantified on Lipsi Island, Greece. Sites were assessed using Pollard walks for butterflies, point‐count surveys for birds, and quadrats for vegetation. There was no significant difference in the abundance or species diversity of butterflies or vegetation among rural and urban locations, which could pertain to the low building density within urbanised areas and the minimal extent of urbanisation on the island. However, urban areas hosted a significantly greater abundance, richness, and diversity of birds compared to rural sites. The community composition of butterflies, birds, and vegetation also differed significantly between urban and rural locations, highlighting the impact of urbanisation on species across a broad range of trophic groups. This study contributes to ecological knowledge on the impacts of urbanisation across multiple trophic levels in island ecosystems, with comparisons across a gradient of island size and urbanisation intensity needed in future research.

Urban areas are expanding exponentially, leading more species of wildlife living in urban environments. Urban environmental characteristics, such as human disturbance, induce stress for many wildlife and have been shown to affect some cognitive traits, such as innovative problem‐solving performance. However, because different cognitive traits have common cognitive processes, it is possible that urban environmental characteristics may directly and indirectly affect related cognitive traits (the ripple effect hypothesis).We tested the ripple effect hypothesis in urban Eurasian red squirrels residing in 11 urban areas that had different urban environmental characteristics (direct human disturbance, indirect human disturbance, areas of green coverage and squirrel population size). These squirrels were innovators who had previously repeatedly solved a food extraction task (the original task). Here, we examined whether and how urban environmental characteristics would directly and indirectly influence performance in two related cognitive traits, generalisation and (long‐term) memory. The generalisation task required the innovators to apply the learned successful solutions when solving a similar but novel problem. The memory task required them to recall the learned solution of the original task after an extended period of time.Some of the selected urban environmental characteristics directly influenced the task performance, both at the population level (site) and at individual levels. Urban environmental characteristics, such as increased direct and indirect human disturbance, decreased the proportion of success in solving the generalisation task or the memory task at the population (site) level. Increased direct human disturbance and less green coverage increased the solving efficiency at individual levels.We also found an indirect effect in one of the urban environmental characteristics, indirect human disturbance, in the generalisation task, but not the memory task. Such an effect was only seen at the individual level but not at the population level; indirect human disturbance decreased the first original latency, which then decreased the generalisation latency across successes.Our results partially support the ripple effect hypothesis, suggesting that urban environmental characteristics are stressors for squirrels and have a greater impact on shaping cognitive performance than previously shown. Together, these results provide a better understanding of cognitive traits that support wildlife in adapting to urban environments. [ABSTRACT FROM AUTHOR]

Climate change is increasing the proportion of river networks experiencing flow intermittence, which in turn reduces local diversity (i.e., α‐diversity) but enhances variation in species composition among sites (i.e., β‐diversity), with potential consequences on ecosystem stability. Indeed, the multiscale theory of stability proposes that regional stability can be attained not only by local processes but also by spatial asynchrony among sites. However, it is still unknown whether and how scale‐dependent changes in biodiversity associated with river flow intermittence influence stability across spatial scales. To elucidate this, we here focus on multiple metacommunities of French rivers experiencing contrasting levels of flow intermittence. We clearly show that the relative contribution of spatial asynchrony to regional stability was higher for metacommunities of intermittent than perennial rivers. Surprisingly, spatial asynchrony was mainly linked to asynchronous population dynamics among sites, but not to β‐diversity. This finding was robust for both truly aquatic macroinvertebrates and for taxa that disperse aerially during their adult stages, implying the need to conserve multiple sites across the landscape to attain regional stability in intermittent rivers. By contrast, metacommunities of truly aquatic macroinvertebrates inhabiting perennial rivers were mainly stabilized by local processes. Our study provides novel evidence that metacommunities of perennial and intermittent rivers are stabilized by contrasting processes operating at different spatial scales. We demonstrate that flow intermittence enhances spatial asynchrony among sites, thus resulting in a regional stabilizing effect on intermittent river networks. Considering that climate change is increasing the proportion of intermittent rivers worldwide, our results suggest that managers need to focus on the spatial dynamics of metacommunities more than on local‐scale processes to monitor, restore, and conserve freshwater biodiversity.

An examination of a few examples of aquifer use shows the importance and fragility of groundwater, with poor management leading to overextraction by individuals and authorities producing subsidence - sinking cities. Freshwater is one of our most precious resources and it is rapidly disappearing, leading to global drying. At the same time, the global and urban populations are increasing, with civil unrest increasing due, in part, to freshwater shortages. The increasing global population and global urbanisation are driving an increase in water use, restriction of aquifer recharge and increased aquifer pollution. It is argued that urban population growth with attendant increased water use, combined with climate change and poor management, is significant in water stress. Particular attention must be paid to the effect of rising populations on local water resources, especially groundwater, and the knock-on effect on urban sustainability. [ABSTRACT FROM AUTHOR]

Urbanisation is indeed a global trend that is significantly transforming societies and landscapes. India, in particular, has been experiencing rapid urbanisation in recent years, and this is fundamentally changing the country’s social and economic dynamics. However, the state of Kerala, located in the southwestern part of India, stands out for its unique pattern of urbanisation, which is closely aligned with its distinctive topography and socio-economic factors. This study offers a comprehensive examination of urbanisation in Kerala, focusing on its unique spatial and temporal characteristics. The spatial analysis of urbanisation in the state reveals that urban development is not concentrated solely within its major cities, but is widespread. These urban clusters align with Kerala’s topographical diversity, with the majority concentrated along the coastal regions in the west, while the eastern highlands of the Western Ghats exhibit fewer urban centres. The state has witnessed a substantial surge in urbanisation rates, with projections anticipating that approximately 68 percent of the population will reside in urban areas by the middle of this century. Understanding these temporal shifts and spatial variations is essential for policymakers and urban planners to effectively address the challenges and opportunities linked to increasing urbanisation.

The COVID-19 pandemic has profoundly affected internal migration patterns worldwide. Most previous studies have reported on pandemic-induced changes in internal migration using data from 2020 and 2021. Therefore, little is known about the pandemic’s medium-term impact. To address this gap, this study investigated an annual series of migration patterns from 2019 to 2023 in Japan. At the municipal level, relationships between net migration rates and population density indicated that the urbanisation trend became weak in 2020, compared to that in 2019, and it was the weakest in 2021. The urbanisation degree became stronger in 2023, increasing to the level in 2020. Using annual inter-municipal migration flows, this study then investigated changes in migration flows to/from and within three major metropolitan areas (Tokyo, Nagoya, and Osaka). The changes in sizes of these flows and migration effectiveness index suggested that the pandemic had the largest impact in the Tokyo metropolitan area, among the three areas, and it stimulated intra-metropolitan migration as suburbanisation, rather than net out-migration as ‘urban exodus’, in Japan. The overall results indicated that the pandemic had the largest impact in 2021, which got smaller as the migration patterns recovered to the pre-pandemic ones in 2023. [ABSTRACT FROM AUTHOR]

This Survey highlights the role of urbanisation as a growth engine for Indonesia. With the country's economy growing steadily, including by 5.11% in the first quarter of 2024, this Survey highlights the vital contribution of urban productivity to national income. Despite growth driven by non-tradable sectors and relatively strong consumption patterns due to Idul Fitri and general election events, urbanised areas face problems that hinder their productivity. Constraints in urbanisation—such as congestion, housing and pollution—decrease urban potential. Further, this Survey discusses institutional policies and alternative urban financing to improve urban productivity and foster sustainable urban development to help strengthen national economic growth.

Happiness is a tool that can contribute towards the betterment of mental illness and is often linked to the well-being of a place. As per the study, nearly five per cent of Indians have a mental illness, with one in every five requiring psychiatric counselling. The tangible built environment and intangible components significantly affect human happiness. The question arises is whether and to what extent do these components of the urban environment affect happiness. The present paper examines the association between the urban built environment and the happiness of a city, taking Bhopal (a fast-growing metropolis in India with a population of 1.79 million according to the 2011 census) as a case study. Based on available data, seven parameters have been selected under urban built environment, the tangible–the 'body' characteristics (public transport, open space, air quality, vegetation index, air pollution, slum, safety and security, and population density), and happiness, the intangible 'soul', which has been studied via sentiment analysis using Twitter data. The focus of this paper, thus, shifts the focus from the relationship between happiness and socioeconomic factors to a broader understanding of the association between seven 'body' variables and their relationship with the intangible 'soul'. It attempts to establish these relation characteristics using regression analysis. The findings suggest that security fears, distance from open spaces, and distance from slums are among the major determinants of happiness. A sense of positivity is also evident among the people living in high-density areas. The present research can help policymakers to understand citizens' sentiments and integrate these with urban development initiatives for the built environment, building a happy city.

The current progressive increase in urbanisation is a contributing factor to the alarming rate of decrease in biodiversity worldwide, so it is critical to propose new solutions that bring nature, and their associated benefits, back to cities. Urban ponds and pondscapes are potential Nature-based Solutions that play a crucial role in the conservation and promotion of biodiversity, as well as providing other ecosystem services. Therefore, it is important to understand people's perception of the contribution that these ponds/pondscapes make in their daily lives. The aim of this study was to assess public perception of the value of the multiple ecosystem services, here referred to as Nature's Contributions to People (NCPs), provided by urban ponds with a focus on biodiversity. To achieve it, we conducted a face-to-face questionnaire survey among 331 visitors of urban parks and nature reserves in a medium-sized European city (Geneva, Switzerland). The results show that people highly value the different contributions provided by urban ponds, and that contact with nature is the main motivation for visiting urban pondscapes. Their positive view about the provided NCPs and also their acknowledgement of an improved quality of life suggest a public acceptance of these ponds. We also found that gender and income do not influence public perception of the contributions provided by urban pondscapes. Additionally, the biodiversity of urban ponds was highly appreciated, but there was a knowledge gap relating to biodiversity conservation, as both native and exotic species were valued equally. In conclusion, ponds are Nature-based Solutions that are very well adapted and accepted in cities, and in the future they should be part of the greening (and blueing) of urban planning to conserve and enhance freshwater biodiversity whilst also providing NCPs.

Land cover change research is salient in providing information for land use planning and management in urban areas. This study therefore analysed land cover change in four local government areas in Ogun State, Nigeria. Using remote sensing and geographic information system, Landsat images were analysed between 2001, 2013 and 2020 with both unsupervised and supervised image classifications. Results showed that between 2002 and 2013, there was a 41.14% decrease in forest area which further reduced by 41.92% by 2020. Agricultural land increased by 66.47% between 2002 and 2013 but reduced by 43.24% by 2020. Urban areas increased by 108.66% between 2002 and 2013 while by 2020 they had gained 42.19% additional land. It is concluded that the 2005–2025 Ogun State regional planning policy has so far been less than effective due to massive ecological change caused by urban expansion in the region.

This paper draws on research on infrastructure‐led development and urbanisation in Nairobi to explore the new urban geographies of rentier capitalism in Africa. Under the banner of Kenya's Vision 2030 national development strategy, Nairobi's agrarian hinterlands have been transformed by major road building projects. These initiatives have catalysed a peri‐urban property boom characterised by the conversion of agricultural and ranching land into urban real estate and the verticalisation of road corridors. The paper identifies four processes of land transformation driving this real estate market expansion: commodification; speculation; autoconstruction; and assetisation. Adopting a multi‐scalar conjunctural approach, it argues that rentier capitalism in this context is spatialised through the dramatic extension of real estate frontiers along the route of peri‐urban road corridors. Development along these corridors assumes a “grey” character that defies conventional formal–informal distinctions, enabling the extraction of large rentier profits and encouraging the further proliferation of frontier spaces.

Emissions of greenhouse gases (GHGs) are a prime concern that needs our attention, not only in megapolitan states but also in developing small states. The increase in GHGs-emission could lead to severe climate change scenarios and global warming. In India, it is measured that the energy sector (68.7%) accounts for a significant GHGs-emission, followed by agriculture (19.6%), industry (6.0%), land use change and forestry (3.8%), and waste sector (1.9%). This article aims to investigate temporal changes and trends in greenhouse gases (GHGs) emissions in the energy sector of India. We have used GHGs-emission as Carbon dioxide (CO2) equivalent and compared the top per capita emitting states versus their total emissions and vice versa. Most of this increase has occurred in small states, where urbanisation, population growth, and economic expansion have been significant factors. Odisha and Maharashtra were listed as top-emitting states releasing more than 240 million tonnes of carbon dioxide equivalent (MtCO2e), mainly through industrial energy and electricity-related emissions, respectively, followed by Chhattisgarh, Gujarat, Uttar Pradesh, Madhya Pradesh, Andhra Pradesh, and West Bengal. In contrast, Chhattisgarh was recorded as the top per-capita emitting state, followed by Odisha. Among all the states studied, Lakshadweep has shown a significant trend in GHGs per capita reduction, while the other shows an increasing trend due to a lack of robust and effective legislation. This review will help to seek the attention of policymakers and the government towards the increasing emissions from the small states which are emerging in day to day life. [ABSTRACT FROM AUTHOR]

Species loss is highly scale‐dependent, following the species–area relationship. We analysed spatio‐temporal patterns of species' extirpation on a multitaxonomic level using Berlin, the capital city of Germany. Berlin is one of the largest cities in Europe and has experienced a strong urbanisation trend since the late nineteenth century. We expected species' extirpation to be exceptionally high due to the long history of urbanisation. Analysing 37 regional Red Lists of Threatened Plants, Animals and Fungi of Berlin (covering 9498 species), we found that 16% of species were extirpated, a rate 5.9 times higher than at the German scale and 47.1 times higher than at the European scale. Species' extirpation in Berlin is comparable to that of another German city with a similarly broad taxonomic coverage, but much higher than in regional areas with less human impact. The documentation of species' extirpation started in the eighteenth century and is well documented for the nineteenth and twentieth centuries. We found an average annual extirpation of 3.6 species in the nineteenth century, 9.6 species in the twentieth century and the same number of extirpated species as in the nineteenth century were documented in the twenty‐first century, despite the much shorter time period. Our results showed that species' extirpation is higher at small than on large spatial scales, and might be negatively influenced by urbanisation, with different effects on different taxonomic groups and habitats. Over time, we found that species' extirpation is highest during periods of high human alterations and is negatively affected by the number of people living in the city. But, there is still a lack of data to decouple the size of the area and the human impact of urbanisation. However, cities might be suitable systems for studying species' extirpation processes due to their small scale and human impact. [ABSTRACT FROM AUTHOR]

Urbanisation alters biodiversity patterns and threatens to disrupt mutualistic interactions. Aside from pollination, however, little is known about how mutualisms change in cities. Our study aimed to assess how urbanisation affects the protective mutualism between ants and aphids, investigating potential behavioural changes in mutualistic ants and their implications for aphids in urban environments. To do so, we studied the protective mutualism between the pink tansy aphid (Metopeurum fuscoviride) and the black garden ant (Lasius niger) along an urbanisation gradient in Berlin, Germany. In nine locations along this gradient, we measured aphid colony dynamics and proxies for parasitism, quantified the investment of ants in tending aphids and conducted behavioural assays to test the aggressiveness of ant responses to a simulated attack on the aphids. We found that aphid colonies flourished and were equally tended by ants across the urbanisation gradient, with a consistent positive density dependence between aphid and ant numbers. However, ants from more urbanised sites responded more aggressively to the simulated attack. Our findings suggest that this protective mutualism is not only maintained in the city, but that ants might even rely more on it and defend it more aggressively, as other food resources may become scarce and more unpredictable with urbanisation. We thereby provide unique insights into this type of mutualism in the city, further diversifying the growing body of work on mutualisms across urbanisation gradients. [ABSTRACT FROM AUTHOR]

Three popular songs of enormous cultural significance are 'In My Life', 'Penny Lane' and 'Strawberry Fields Forever', all released by the Beatles in the 1960s and all set in the same part of Liverpool. In an original investigation, this article looks into the growth of that part of the city from the mid-nineteenth century to the 1950s, examining the changes to the landscape. This was as the initially rural environment gave way to a typical twentieth-century townscape of houses, roads, parks and schools. The memories of people who resided there are related and these along with old maps, photographs, newspaper articles and census details are examined to give a sense of the lived-in location that inspired the lyrics of Paul McCartney and John Lennon. The phenomenon of palimpsest – ancient features slightly visible underneath modern ones – is applied to this study of the location and a new concept of inverse palimpsest – the old consciously superimposed on the new – is put forward in a novel approach to landscape analysis.

Current knowledge about the impacts of urbanisation on bird assemblages is based on evidence from studies partly or wholly undertaken in the breeding season. In comparison, the non‐breeding season remains little studied, despite the fact that winter conditions at higher latitudes are changing more rapidly than other seasons. During the non‐breeding season, cities may attract or retain bird species because they offer milder conditions or better feeding opportunities than surrounding habitats. However, the range of climatic, ecological and anthropogenic mechanisms shaping different facets of urban bird diversity in the non‐breeding season are poorly understood. We explored these mechanisms using structural equation modelling to assess how urbanisation affects the taxonomic, phylogenetic and functional diversity of avian assemblages sampled worldwide in the non‐breeding season. We found that minimum temperature, elevation, urban area and city age played a critical role in determining taxonomic diversity while a range of factors—including productivity, precipitation, elevation, distance to coasts and rivers, socio‐economic (as a proxy of human facilitation) and road density—each contributed to patterns of phylogenetic and functional diversity. The structure and function of urban bird assemblages appear to be predominantly shaped by temperature, productivity and city age, with effects of these factors differing across seasons. Our results underline the importance of considering multiple hypotheses, including seasonal effects, when evaluating the impacts of urbanisation on biodiversity. [ABSTRACT FROM AUTHOR]

Introduction: Diabetes is a multifactorial disease with far-reaching consequences. Environmental factors, such as urban or rural residence, influence its prevalence and associated comorbidities. Haryana—a north Indian state—has undergone rapid urbanisation, and part of it is included in the National Capital Region (NCR). The primary aim of the study is to estimate the prevalence of diabetes in Haryana with urban–rural, NCR and non-NCR regional stratification and assess the factors affecting the likelihood of having diabetes among adults. Methods: This sub-group analysis of the Indian Council of Medical Research-India Diabetes (ICMR-INDIAB) study (a nationally representative cross-sectional population-based survey) was done for Haryana using data from 3722 participants. The dependent variable was diabetes, while residence in NCR/non-NCR and urban–rural areas were prime independent variables. Weighted prevalence was estimated using state-specific sampling weights and standardized using National Family Health Survey-5 (NFHS-5) study weights. Associations were depicted using bivariate analysis, and factors describing the likelihood of living with diabetes were explored using a multivariable binary logistic regression analysis approach. Results: Overall, the weighted prevalence of diabetes in Haryana was higher than the national average (12.4% vs. 11.4%). The prevalence was higher in urban (17.9%) than in rural areas (9.5%). The prevalence of diabetes in rural areas was higher in the NCR region, while that of prediabetes was higher in rural non-NCR region. Urban–rural participants' anthropometric measurements and biochemical profiles depicted non-significant differences. Urban–rural status, age and physical activity levels were the most significant factors that affected the likelihood of living with diabetes. Conclusions: The current analysis provides robust prevalence estimates highlighting the urban–rural disparities. Urban areas continue to have a high prevalence of diabetes and prediabetes; rural areas depict a much higher prevalence of prediabetes than diabetes. With the economic transition rapidly bridging the gap between urban and rural populations, health policymakers should plan efficient strategies to tackle the diabetes epidemic.

This paper is a synthesis of zooarchaeological evidence from 27 medieval and post-medieval sites from Finland. These faunal samples derive from rural, town, manor, castle and ecclesiastic sites, and their production and consumption patterns were examined by studying the role of the major domesticates (cattle, sheep, goats and pigs). As taxonomic abundance in faunal material may be altered by taphonomic processes, such as burning, these factors were assessed before comparison. The animal husbandry system in Finland was shaped by environmental constraints that limited the number of animals that could be kept over winter. However, some specialisations were observed within the frame of the basic pattern. This paper demonstrates the usefulness of zooarchaeological data in the study of animal husbandry and consumption and production patterns. These findings support data integration as a useful tool for understanding general large-scale processes, such as urbanisation, development, environmental adaptation and the specialisation of animal production.

In our initial paper we presented the urban as a question of democracy. The aim was to advance thinking about democracy through thinking about the urban, to use contemporary urban theory to theorise contemporary democracy. Seeing Democracy Like a City involves looking differently at the urban world out there, but also looking a little differently at the world of urban research in journals like this one. Underpinning our work was the epistemological release arising from an urban ontology of politics, as the state shuffles stage right and urbanity moves centre stage. The forum articles suggest that seeing democracy like a city can be inspiring. But the question of how transformative this approach can actually be is posed by all the authors. In this rejoinder we highlight some of the issues we think are crucial to address this question and to unlock the transformative potential of an urban democracy. [ABSTRACT FROM AUTHOR]

In this commentary on Beveridge and Koch's 'Seeing Democracy Like a City', I draw their stimulating ideas into dialogue with Sydney's green ban movement – a remarkable enactment of urban democracy from 50 years ago whose legacy remains enshrined in the built fabric and in the political imaginary of my city. This dialogue is used to offer some reflections on elements of their argument concerning the role of institutions in urban democratic theory and practice, the historicity of the association between the urban and democracy, and the place of equality in democratic forms of organisation and self-governance.

Urbanisation is changing landscapes, social relations and everyday lives across the globe. But urbanisation is also changing the ways democracy is understood and practiced. Nevertheless, the relation between urbanisation and democracy remains conceptually and empirically underdeveloped. Our aim in this paper is to provide a novel way of thinking about this relationship that addresses two limitations in current debates. First, there is the dominant view that just as urbanisation dissolves the actual, material city it also dissolves the city as a democratic project. We challenge this understanding, arguing that across the globe claims for and forms of urban collective self-rule signal that the city retains democratic significance in a very specific sense: as an object of practice and thought the city is a source and stake of the urban demos. Second, there is a tendency to either restrict the question of democracy to state-centred forms of political action or to place democracy completely outside the realm of the state. We argue however that urbanisation unsettles seemingly fixed boundaries between the state and society and thus opens the possibility of weaving together a new democratic fabric encompassing both. In addressing these two strands of debate together, we outline a democratic politics of urbanisation that shifts perspectives from institutions to practices, from jurisdictional scales to spaces of collective urban life. Seeing democracy like a city, we argue, foregrounds a way to reimagine and to re-locate democracy in the everyday lives of urbanites. [ABSTRACT FROM AUTHOR]

Sub-Saharan Africa (SSA) is undergoing rapid urbanization, yet research comparing urban expansion and agricultural land loss in peri-urban areas is scarce. This study utilizes multi-temporal Landsat imagery to examine the impact of urban growth on agricultural land and fragile ecosystems in Kampala (a mega city) and Mbarara (a regional urban center) in Uganda. We distinguish between random and systematic land-use and land-cover (LULC) transitions in the landscape. The results reveal substantial urban expansion. Kampala's urban area surged from 7.14% in 1989 to 55.10% in 2015, while Mbarara increased from 6.37% in 2002 to 30.95% in 2016. Correspondingly, agricultural land decreased, from 48.02% to 16.69% in Kampala, and from 39.92% to 32.08% in Mbarara. Notably, a significant proportion of urban growth in both cities encroached upon agricultural land (66.7% in Kampala and 57.8% in Mbarara). The transition from agricultural to built-up areas accounted for 14.72% to 28.45% of the landscapes. Additionally, unsustainable practices led to the conversion of wetlands and forests to agricultural land, with approximately 13% of wetlands and 23% of Savannah and forests being converted between 2001 and 2015. These findings underscore the necessity of monitoring LULC changes for sustainable urban growth management, emphasizing the importance of preserving agricultural land and ecosystems to ensure present and future food security. This research contributes to the understanding of urbanization's impact on peri-urban agricultural land and ecosystems in SSA, providing insights that are crucial for informed urban planning and policy formulation aimed at sustainable development in the region.

Rapid urbanization across the world has drawn attention to the unique state of urban woodlands. New Delhi is one of the world's most populous cities; yet, it harbours several woodlands that support a variety of wildlife. The persistence of mesopredators like the gplden jackal (Canis aureus Linn.) in the city is intriguing and provides an opportunity to explore coexistence in an urban context. Using a combination of camera trapping and occupancy modelling, our study aims to understand the habitat use, distribution, and urban adaptations of the jackal in Delhi's Central Ridge Reserve Forest. Preliminary analysis shows extensive habitat use and sophisticated adaptations including adjustments in activity patterns in response to human activity and competition from feral dogs. The study also demonstrated behavioural adaptations, particularly in terms of foraging, denning, and coexistence with other species, which enable these urban populations of golden jackals to persist in the city. The study indicates the need for newer frameworks for conservation of synanthropic wild fauna that persist in calorie-rich urban environments. [ABSTRACT FROM AUTHOR]

An examination of a few examples of aquifer-use shows the importance and fragility of groundwater, with poor management leading to over-extraction by individuals and authorities producing subsidence – sinking cities. Freshwater is one of our most precious resources and it is rapidly disappearing, leading to global drying. At the same time, the global and urban populations are increasing, with civil unrest increasing due, in part, to freshwater shortages. The increasing global population and global urbanisation are driving an increase in water use, restriction of aquifer recharge and increased aquifer pollution. It is argued that urban population growth with attendant increased water use, combined with climate change and poor management, is significant in water stress. Particular attention must be paid to the effect of rising populations on local water resources, especially groundwater, and the knock-on effect on urban sustainability.

Abstract Housing is a fundamental human need, yet access remains a significant challenge in Africa, particularly for low-income families. Rapid urbanization exacerbates this issue, highlighting the need for innovative and sustainable housing strategies that can support urban growth and improve living conditions for these families. This study employs a rapid review methodology to identify and analyze sustainable innovative affordable housing (SIAH) strategies suitable for low-income families in African cities. Through a comprehensive literature search and thematic analysis, the review explores housing strategies such as mixed-use developments, incremental housing, low rental housing, inclusionary housing, 3D printing, upcycling, micro-housing, community-led housing, co-housing, and green building practices. These approaches/strategies are not mutually exclusive and can often overlap or be integrated to address housing challenges comprehensively. The findings highlight that these strategies can significantly enhance spatial justice and promote sustainable urban development. However, challenges such as material scarcity, regulatory complexities, and societal resistance must be addressed. The study emphasizes the need for policy support, public–private partnerships, community engagement, financial incentives, and capacity building to ensure successful implementation of these strategies. The paper contributes to the existing body of knowledge by providing actionable recommendations for policymakers, urban planners, and housing advocates, aiming to foster inclusive, equitable, and sustainable cities in Africa. Future research could delineate the strategies into distinct categories based on their nature and purpose (strategy, method/tool, practice etc.), providing a clearer framework for understanding and implementation.

The article presents the achievements of the “Diagnosis of the state of Poland’s spatial economy”, developed in 1981–1983, which critically analyses the effects of the thirty-year impact of the principles of building socialism on Poland’s spatial economy. These effects are related to the elements of the current state of the country’s spatial management, which leads to the conclusion that many of the unfavourable phenomena and processes of that time also occur today, after 30 years of market economy and the democratic system. The article ends with a proposal of research on the contemporary spatial conditions of the country’s development.

This study examines land use transformations and their impact on groundwater quality fluctuations in Chengalpattu district, Tamil Nadu. Chengalpattu is a rapidly urbanizing coastal region in South India. Landsat 5 and 9 satellite imagery were utilized to create land use land cover (LULC) maps for 2011 and 2021, with overall accuracies of 82.20% and 85.71%, respectively. The analysis showed significant growth in built-up and fallow lands due to urbanization, which has altered LULC. Groundwater Quality Index (GQI) was generated using seven groundwater quality parameters, adhering to World Health Organization (WHO) standards. The mean GQI showed slight fluctuations during pre- and post-monsoon periods, with a declining trend in pre-monsoon seasons. The study area predominantly experiences moderate groundwater quality, with fewer areas of low and high quality. The findings indicate that land use transformation significantly impacts groundwater quality, emphasizing the need for sustainable urban planning and water resource management in the region.

This study focuses on urban farming practices in Bandung, West Java, known as Buruan SAE, a programme initiated by the Department of Food Security and Agriculture, Bandung. The objectives of this study are to analyse the effects of urbanisation on urban farming and to explore the potential of urban farming in supporting food security. This study uses a qualitative approach. The results of the study show 3 important issues: the diverse production of urban farming is able to meet the food needs of community members and some have already become independent farmers; there has been a change in the attitude of the people of Bandung city, through urban farming they have become ‘farmers’ a completely new activity for them; urban farming provides a source of income for the urban community. These findings suggest that urban farming can enhance the sustainability of the Buruan SAE community.

The urbanisation growth causes problems related to the provision and consumption of resources, ecology, and social living conditions in cities. The purpose of the article is to study the dependence of metabolic factors and the level of urban conveniences on the urbanisation level and to justify the need to monitor these processes and improve the management of urban systems with the purpose to achieve sustainable development objectives. Three aspects of the problem of urban metabolism and sustainable development of cities are considered in the article. They are energy consumption by megacities, social aspects of metabolism and growth of megacities, problems of urban improvement. The increasing risks of negative impact of urban growth on the environment and living conditions has been proven. It is shown that the resettlement flow of village residents to cities, especially large ones, remains high despite the deterioration of the environmental situation in large cities and the lag in the urban infrastructure development from the population growth rate. The expediency to expand the context of the urban metabolism problem was noted, including the exchange of resources between urban and rural to reduce spatial inequality, and to increase the sustainability of urban and rural settlements.

ABSTRACTAmidst the rapid urbanisation, the ecological environment of plateau lake basins faces significant challenges. To better coordinate the relationship between urbanisation development and ecological environment construction, this paper conducts an analysis and assessment of the ecological resilience and urbanisation coupling coordination in Dali Prefecture based on socio-geographical spatial data. Initially, an assessment model for ecological resilience is established using resilience theory. Subsequently, the urbanisation development level is evaluated based on panel data. Finally, a coupling coordination model is employed to calculate the coupling coordination between the two aspects. The results indicate: (1) a rapid increase in basin urbanisation from 2010 to 2019, particularly between 2010 and 2015; (2) a continuous expansion of low-value ecological resilience areas across the entire basin, with a predominance of townships experiencing fluctuating decreases or stagnation, leading to an overall negative trend in ecological resilience indices; (3) evident spatial and temporal disparities in coupling coordination between the two systems in the basin’s villages and towns, primarily reflected in differences in coupling coordination types, with a few towns consistently exhibiting environmental lag. This study introduces a customised ecological resilience model for the Erhai Basin, enhancing comprehension of urbanisation-ecological resilience dynamics in plateau lake basins.
