Authors:Abdul-Ghaffar Chaudhry, Houshmand Masoumi, Hans-Liudger Dienel Abstract: Urban mobility behavior is influenced by complex interrelations of personal attitudes, neighborhood design, emerging digitalized shared mobility services, and urban governance. The transformation of urban mobility ecosystems in the Middle East and North African (MENA) and the South Asian (SA) regions lacks an in-depth comparative review to understand the determinants of mobility attitudes and mode choices. The objective of this paper is to systematically study the existing literature on cities in the MENA and SA regions to provide a comparative review of the analyses and the findings on urban mobility attitudes in light of prevailing societal conditions and urban-spatial forms. A systematic methodology was deployed to shortlist recently published journal papers from the years 2000 to 2022 for the MENA and SA regions. Application of the (shortlisting) methodology has identified 43 studies from the MENA region and 43 papers from the SA region to be most suitable for the review of comparative analysis of urban mobility behavior. The review found that travel choices in both MENA and the SA regions are impacted by the usual determinants such as demography, socio-economic characteristics, vehicle ownership, and the quality and maturity of (urban transport) spatial forms. The mobility behavior in these regions, is to some extent, can be said to be in alignment with the observed behavior across the developed western cities elsewhere in Europe and North America. The review identified that in both the MENA and the SA regions, mobility choices are also influenced by certain additional factors, such as cultural norms, adverse climatic conditions and socio-economic standings, etc. The literature indicates that ethnic and income disparities are deeply embedded in the socio-spatial arrangements of the cities in the MENA and SA regions. Future research can assess the relative influence of these factors and to determine correlations between mobility attitudes and urban forms to build better cities. PubDate: 2023-01-25T00:00:00Z
Authors:Etienne Nel, Lochner Marais, Zolile Mqotyana Abstract: IntroductionSouth Africa has had an extraordinarily heavy reliance on coal to fuel its economy, and it is one of the highest carbon dioxide emitters per capita globally. Current moves aligned with COP26 and recently announced Western support for a Just Transition Partnership to support decarbonisation in South Africa and replace coal fired power stations with renewables are to be welcomed. That said, the majority of South Africa's coal mines, thermal power stations and the currently important coal export industry are located in Mpumalanga's Coal-Belt, an area which has and will continue to experience significant social and economic trauma as mines close and workers needs to be reskilled. There are currently over 100,000 workers in the coal and related industries in this region.MethodsThis paper draws on international and South African evidence of the effects and responses to mine closure, regional resilience theory and evolutionary economic geography theory to analyse the implications and prospects for economic renewal as the coal industry winds down. Evidence is sourced form secondary material including government and industry policy statements and media articles, while primary material was sourced from key informant interviews.ResultsTransitioning this region of South Africa from its virtual mono-economy based on coal presents challenges which this paper highlights. While support from international sources to help make this transition into renewables will be of considerable benefit, significant challenges need to be addressed to ensure that difficulties are overcome, and the risks of the resource curse experienced in many developing countries are minimized.DiscussionProcesses may need to be put in place to ensure that the ambitious goal of transitioning from coal to renewables can be achieved, finances and management well-targeted, and a sense of security given to outside investors to help fund the transition, but also broader economic diversification. In parallel to ensure the “transition is just” mechanisms also need to be put in place, by the state and the investors, to ensure that those citizens unable to transition are empowered and engaged in their community to stem the risk of the inevitable frustration and social disturbance that exclusion from the economy and living with declining services creates. Whom should be putting these processes into place also needs consideration given that existing organizations are already struggling. Though not an easy task, it is hoped that this paper sheds some light on the various issues and encourages consideration of the ways to address them. PubDate: 2023-01-19T00:00:00Z
Authors:Luisa Moretto, Giuseppe Faldi, Federica Natalia Rosati, Jacques Teller Abstract: This study questions the processes of technical and governance hybridisation in the coproduction of water services in cities of the Global South. The existing literature addresses the compensatory role that water services coproduction plays in urban and peri-urban areas, where access to centralised and reliable water resources is often lacking. However, less research focuses on the evolution of coproduced practices in relation to wider transitions of urban spaces, water resources, centralised infrastructure, and service delivery strategies. Still, the resulting technical and governance configurations stemming from these situations are largely unexplored. This study considers four cities, namely, Hanoi (Vietnam), Dar es Salaam (Tanzania), Cochabamba (Bolivia), and Addis Ababa (Ethiopia). All our case studies are somewhat characterised by rapid land-use changes, juxtaposition of rural and urban activities, varying urban typologies, and increasing poverty, sociospatial inequality, and exclusionary service provision. We draw on data collected from field surveys and participatory workshops with inhabitants and institutional actors between 2017 and 2020 as part of a recent research project. We explore the evolution of water coproduction from technological and governance perspectives. The cases analysed in the research highlight that the time and social development of water coproduction do not follow a linear path. It is rather characterised by cycles of emergence, maturation, and decline. It may build upon pre-existing forms of community-based water management that were established in rural areas (for irrigation or water harvesting, for instance). The results show that water coproduction may have different evolutions, entailing different hybridisation processes. Water coproduction can be characterised by either complementary or concurrent service configurations, by blurring actor categories, and by different drivers in the hybridisation process. Ultimately, evolution in urban coproduced practices appears as a process of technical and governance hybridisation, rather than as final and fixed hybrid systems. PubDate: 2023-01-18T00:00:00Z
Authors:Elizelle Juanee Cilliers Abstract: Despite the expanding scientific understanding that green spaces are substantially beneficial to urban communities and their host cities, along with the evidence that some global cities are making progress to include nature as part of mainstream planning, this article argues that social perceptions also play a critical part in the successful planning and realization of urban green space provision in practice, especially in the Global South. This research thus reflected on the pedagogical effect on the social perception of the presence of green spaces in an urban area. To understand the impact of social perceptions on the valuation of green spaces, this article investigated the views of a convenience sample of professionals working in the Built Environment in South Africa and employed frequency distribution, two-way frequencies, and statistical measures to draw conclusions pertaining to the perception of green space value. The research illustrated that social perceptions inform how urban risks are perceived and that these perceptions of green space are often limited due to a lack of knowledge and awareness. The research exemplified that the actual community benefit provided by green spaces should be better articulated to gain traction in practice and that the appreciation and use of these urban green spaces should also be understood from a context-based and personal valuation perspective, to position these spaces as the critical resource and public good. This research concluded that social perceptions should be comprehensively understood, especially in the quest of realizing green(er) spaces and cities in the Global South.

Authors:James Chakwizira Abstract: Insecurity, violence, and xenophobia manifest at different geographic scales of the South African landscape threatening to compromise, reverse, derail, and contradict the envisaged democratic processes and gains in the country. Since the dawn of the new democracy in 1994, the South African landscape has witnessed surges of different scales of violence, protests, riots, looting, criminality, and vigilantism in which question marks have been raised with respect to the right to the city or urban space and the right to national resources and opportunities, i.e., access, use, distribution and spread of social, economic, environmental, and political resources and benefits. Louis Trichardt is a small rural agricultural town located in the Makhado municipality of Vhembe District in Limpopo Province, South Africa. In the study, this town is used as a securityscapes lens of analysis to explore urban conflict and violence. The relative importance index (RII) was used to measure the barriers and solutions to advance safe neighborhoods' settlements and built environment areas in the study area. In this way, issues influencing the performance of reconfigured securityscapes in Louis Trichardt were explored by highlighting how new town neighborhood securityscape initiatives and activities are contributing to space, place, and culture change management transitions. The discussion pressure and pain points revolve around the widening societal inequalities, deepening poverty, influx of (ll)legal migrants and migrant labor, lingering xenophobia, and failure to embrace the otherness difficulties in the country. Findings highlight the options for urban (in)security, social (in)justice, and (re)design in post-colonies possibilities, limitations, and contradictions of securityscapes in (re)configured spaces of Louis Trichardt. Policy and planning proposals to improve safety and security spatial logic and innovation are explored. The critical role of community and local neighborhood watch groups in complementing state security and private registered security systems is one way of tackling this matter.

Authors:Zixin Dou, Yanming Sun, Beibei Wu, Chuliang Wu Abstract: This study aims to analyze the factor affecting the urban industry development in Guangzhou. Based on push-pull-mooring theory, we explain the reasons for choosing the above indicators and use order parameters to analyze their impact on the urban industrial development. The results show that: (1) Environment has an obvious promoting effect on the urban industrial development. This shows that the current environment and the urban industrial development have reached a balance. (2) Technology has a positive impact on the urban industrial development, but it needs to go through the technology running in period smoothly. (3) Different from other factors, finance has a crowding out effect on industrial development. However, the development of finance will promote the rapid development of industry in Guangzhou. (4) The impact of finance, technology and green on UID is applicable to different development stages of UID, that is, these variables are related. Lastly, we provided development suggestions for Guangzhou. This will lay a foundation for promoting its industry. PubDate: 2023-01-12T00:00:00Z
Authors:Anna S. Persson, Veronica Hederström, Iris Ljungkvist, Lovisa Nilsson, Liam Kendall Abstract: Wild insect pollinators are essential to cultivated and natural ecosystems globally. Today, many pollinator species are declining. One reason is a general lack of flowering habitats at landscape scales. However, urban areas, including private gardens, may provide flowers, and constitute beneficial habitats for pollinators. Here, we evaluate the ecological outcomes of a citizen science campaign run by the Swedish Society for Nature Conservation (SSNC) (called “Operation: Save the bees”), encouraging citizens to incorporate interventions beneficial to wild pollinators (garden meadows, flower plantings, and bee hotels) in their gardens. Data on insect observations and flowering plants were collected through online questionnaires at the end of the growing season. In total, we received 3,758 responses for the three interventions. We found that participants were more likely to observe many pollinators (as opposed to few or none) in more species rich garden meadows, and in larger and older plantings. The surrounding environment also affected pollinator abundance: fewer pollinators were observed in plantings in dense urban areas. Direct counts of pollinators during 10-min surveys correlated strongly to the simplistic abundance assessment (none, few, or many insects seen over the summer season). Bee hotel occupancy was positively related to local flower availability and bee hotel age. Smaller nest holes ( PubDate: 2023-01-11T00:00:00Z
Authors:Nina Liu, Yingying Chen, Fei Su Abstract: Once the integrated urban-rural development enters a high-quality development stage, multiple dimensions would be reflected in population, space, economics, society, and environment, which will further advance sustainable development. An integrated urban and rural development have shown different features, rules, and models amid different social systems and in different development stages. Therefore, it's urgent to scientifically measure the integration level of rural and urban areas, revealing the spatial differences, characteristics, and internal mechanism. Targeting the 41 cities within the Yangtze River Delta, this paper evaluates the integrated urban-rural development in this area based on the global principal component analysis, explores its spatial agglomeration and evolution pattern by ESDA method, analyzes the principal factors that result in the spatial differences in integrated urban and rural development in the Yangtze River Delta and their interactive relations by the geographical detector, and discusses the regional differences between those influencing factors by the geographical weighted regression method. The results indicate that (1) the integrated development of the 41 cities is not balanced and there is a great difference between different cities. (2) The integrated development of this area has shown the apparent feature of geographical agglomeration, or in other words, the central cities have become the forces that drive the development of neighboring cities. (3) Since integrated urban-rural development is influenced by economic development, basic infrastructure, government support, and industrial structure, all regions should put forward suggestions for the formulation of policies accordingly based on realities.

Authors:Furqan Asif, Laura Beckwith, Chanrith Ngin Abstract: The rapid growth Cambodia has experienced over the past two decades has resulted in a dramatic transformation of its built environment, in particular, its largest city, Phnom Penh. The shape this urban development has taken echoes that of many developing countries whose urban landscape features gleaming skyscrapers, apartment buildings, and edge-city projects spread across a rapidly expanding urban area. Such a pattern of urbanization is occurring in Phnom Penh while the city faces increased flooding, lack of adequate urban infrastructure, and vulnerability to impacts of climate change. At the same time, embedded within national policy discourses of climate change and social/economic planning, and backed by international donors, are calls for strengthening or developing resilience. Yet, in the city there are signs of land dispossession, marginalization, inequality, and exacerbated poverty. In parallel to high-level discourses of urban resilience, on the ground there have been “everyday forms of resilience” that show how people enact and build resilience through collective action and advocacy for the rights of the urban poor. In reconciling this dichotomy, we argue that the continued reproduction of a technocratic-focused discourse on resilience in Cambodia by national and international actors overshadows the everyday contestations, strategies and resilience-making practices of people in urban areas. Through three examples, we showcase the varying ways in which these contestations and strategies occur in, and despite, an environment of suppression, and how they are challenging the status quo. In doing so, we shed light not only on the politics of resilience but, more importantly, the implications of the political agendas that ultimately contribute to exacerbating vulnerabilities of urban residents, even as calls continue for increased urban “resilience.” PubDate: 2023-01-06T00:00:00Z
Authors:Mariana V. N. Arena, Rogério H. Toppa, Marcos Martines, Isabel Alves-dos-Santos Abstract: Contemporary urban ecology views cities as heterogeneous and dynamic ecosystems, composed of biotic, physical, social, and man-made systems. In this context, urban beekeeping stands out as a growing practice that demands further studies. Many species of stingless bees (tribe Meliponini) have adapted to urban areas, while others are more sensitive. The composition of the surroundings where the beehive is located is important for the health of the nests and quality of the bee products. This work used bee capture and release techniques to evaluate the use of this methodology for releasing and monitoring native bees in urban areas and to identify whether proportion of green and gray urban nature areas affect the flying activities of stingless bees in an urban landscape. We used nests of Melipona quadrifasciata (mandaçaia), a species of stingless bee native to the Atlantic Rainforest, from three meliponaries located in different parts of the city of São Paulo. The travel time of bees in the landscape were related to the green urban areas up to 900 m in diameter from the meliponaries. Although we did not find a relationship between green areas and bee return times and numbers, it was noticeable that there was variation between the study areas, indicating that the release and monitoring methodology can be used in urban areas following the recommended modifications.

Authors:Katharina Hartmann, Jenny Palm Abstract: A rapid decarbonization of the energy sector is key for mitigating climate change and in this transformation a transition to renewable heating is essential. To date, most attention in both research and policy on decarbonization has been on electricity and transport systems, with less interest in the heating system. Half of the EU's final energy consumption is made up by the heating and cooling sector, making this an important sector for reducing fossil fuel consumption. This article addresses the lack of research on decarbonization of heating by answering the question, what barriers and drivers do Thermal Energy Communities (TECs) perceive when trying to enter the market and play a role in the decarbonization of heating in Germany' Eight TECs and four umbrella organizations in Germany have been interviewed about their experiences of initiating and running a TEC. The results show, amongst others, that the political support of municipalities is put forward as an essential driver and important factor for success. However, barriers for municipalities to get involved were often that they lacked expertise, capacity and financial resources. An important driver for TECs was the involvement of local experts and professionals who could support the volunteers often in charge of a TEC. The results show that TECs that included professionals had an advantage in building heating systems, as they could better address their complexity and high initial costs. Another prevalent result was the need for community engagement and citizen mobilization, which is a greater need in heating projects compared to those focusing on electricity, due to community heating systems requiring a substantial number of customers for profitability.

Authors:Sarah Cipkar Abstract: Using the model of a Just City the goal of this paper is to contribute to the discussion of additional dwelling units (ADUs) by connecting disparate literature on ADUs in North America to the body of spatial justice and posit a way forward that recognizes the drawbacks of a system of individual property ownership, while hypothesizing that more equitable outcomes could be achieved through the inclusion of ADUs within the private market system through government regulation. This paper argues that through the lens of equity, democracy, and diversity, ADUs have the potential to lead to more just outcomes within a privatized market housing system, where homeownership is both the dominant tenure and ideology. Accounting for the inequities of informal ADUs and the contradictions within a capitalist, financialised housing system, new pathways are conceived to both encourage and regulate the ADUs to ensure security of tenure and protection against market pressures.

Authors:Sara Noemie Plassnig, Marisa Pettit, Kristin Reichborn-Kjennerud, Ina Säumel Abstract: Sustainable, productive and biodiversity-friendly urban landscapes are a strategic step in transitioning to future-proof, liveable and healthy cities Edible nature-based solutions, otherwise known as “Edible City Solutions”, comprise a wide range of different forms of sustainable urban food production, distribution and consumption which use innovative principles of ecological design combined with closed material and energy flows. Edible City Solutions contribute to a local green economy, reduce cities' overall ecological footprint, enhance social cohesion, human health and wellbeing and contribute to bridging the gap between “farm and fork”. These benefits have been tested and monitored in Living Labs where a wide portfolio of different solutions have been implemented and scaled in order to accelerate their uptake and use in urban landscapes. The study documents and analyses different scaling practices and activities of the co-created Living Labs – together with local actors within the “scaling community” in Andernach, Berlin, Havanna, Oslo and Rotterdam. We follow a mixed method approach and analyse data by applying the different scaling pathways of scaling up, scaling deep, scaling wide, scaling across and scaling soft previously identified through a systematic literature review. Results are presented as ongoing scaling stories, experiences and challenges in the Living Labs. The study also highlights examples of scaling practices beyond the Living Labs and suggests strategic plans for future scaling. Scaling processes, strategies and approaches are critically reviewed and discussed. Observations are condensed into eleven recommendations for scaling edible nature-based solutions.

Authors:Beacon Mbiba Abstract: This desktop study paper suggests a “flows and livelihoods” framework for comparative studies on displaceability in the context of infrastructure and investment/projects in diverse post-colonial settings. It uses the ongoing upgrading of Mbudzi (Goats) interchange, in Harare, to discuss the utility of this framework in addressing diverse sustainability and human security questions irrespective of scale, scope and settings of the project. Thus, the paper contributes to integrated ways of understanding dynamics and sustainability of infrastructure investments. In the process, it also responds to calls on the need for exemplars on how theory can be integrated into planning research. Ultimately, what it offers is a heuristic device for cross-sectional and time-series studies. PubDate: 2022-12-21T00:00:00Z
Authors:Cian McCarroll, Federico Cugurullo Abstract: In this perspective piece we use a case study of Phoenix (Arizona) to explore the ways in which the implementation of autonomous vehicle technology is tied to the political economy of the city. We highlight the potential urban benefits that can stem from the use of autonomous vehicles, while also bringing to the fore the necessity of governance in realizing these same benefits. By using Phoenix as a case study, we illustrate the dissonance that exists between policymakers within government and the future urban imaginaries that are used as reasons to justify Phoenix as a test ground. By viewing the position of stakeholders within industry and within government we address the individual and political gains that adoption of such technology can bring on an inter-state competitive level. These dynamics of market competition, combined with a lack of proactive engagement in urban planning show that the potential urban benefits that can be brought on by the autonomous vehicle are left solely to the imagination.

Authors:Pablo Torres-Lima, Kristen Conway-Gómez, Karla Almanza-Rodríguez Abstract: The current state of conceptual approaches to study peri-urban areas focusses foremost on land use changes and informal human settlements because of cities' urban expansion. The uncertainty and insecurity related to the expansion of the metropolis increases the complexity of the harmonization of institutional systems and the integration of local actors and communities to respond to urban planning processes. We address the calls for an examination of local community involvement in governance processes in Milpa Alta (MA), a peri-urban agricultural area in Mexico City (CDMX), a megacity with strong peri-urbanization trends. Livelihoods and adaptive capacities approaches were applied for analysis of the results of surveys, interviews, and participatory workshops. We report that in MA there is no integral adaptive capacity to deal with the effects of urban pressures, regional environmental deterioration, and local agricultural dynamics. There are close linkages between limited participation, low local organizational levels, and the social commitment of the population dedicated to agriculture and the existing distrust of government institutions. Sustainable management of peri-urban areas requires the creation of collaborative networks from which local institutional norms can emerge. Furthermore, peri-urban areas require the establishment of participatory systems for decision-making, including the recovery of community and local councils, to activate processes supportive of achieving peri-urban adaptive governance. We conclude that “local is not enough,” based on an adaptive governance approach, to understand the paradigms of decision-making processes and public and local interests in resource management for agriculture in this peri-urban case study.

Authors:R. Patrick Bixler, Marc Coudert, Steven M. Richter, Jessica M. Jones, Carmen Llanes Pulido, Nika Akhavan, Matt Bartos, Paola Passalacqua, Dev Niyogi Abstract: The growing frequency and intensity of extreme weather events have placed cities at the forefront of the human, social, economic, and ecological impacts of climate change. Extreme heat, extended freeze, excessive precipitation, and/or prolong drought impacts neighborhoods disproportionately across heterogenous urban geographies. Underserved, underrepresented, and marginalized communities are more likely to bear the burden of increased exposure to adverse climate impacts while simultaneously facing power asymmetries in access to the policy and knowledge production process. Knowledge co-production is one framework that seeks to address this convergence of disproportionate climate impact exposure and disenfranchised communities. Co-production is increasingly used in sustainability and resilience research to ask questions and develop solutions with, by, and for those communities that are most impacted. By weaving research, planning, evaluation, and policy in an iterative cycle, knowledge and action can be more closely coupled. However, the practice of co-production often lacks reflexivity in ways that can transform the science and policy of urban resilience to address equity more directly. With this, we ask what kind of co-production mechanism encourage academic and non-academic partners to reflect and scrutinize their underlying assumptions, existing institutional arrangements, and practices' How can these efforts identify and acknowledge the contradictions of co-production to reduce climate impacts in vulnerable communities' This paper presents a framework for reflexive co-production and assesses three modes of co-production for urban resilience in Austin, Texas, USA. These include a multi-hazard risk mapping initiative, a resident-driven community indicator system for adaptive capacity, and a neighborhood household preparedness guide. We establish a set of functional and transformational criteria from which to evaluate co-production and assess each initiative across the criteria. We conclude with some recommendations that can advance reflexive co-production for urban resilience. PubDate: 2022-12-09T00:00:00Z
