Researchers highlight that one significant intrinsic motivation for taking part in co-creations is a sense of place. Vice versa, some scholars indicate an enhanced sense of place can be achieved through community participatory strategies and place-making. However, there is a noticeable absence of empirical investigations into this seemingly reciprocal relationship. This study uses the Crow Island Beach Park development in Sri Lanka as a case study to explore the relationship between co-creation experience and the sense of place. Following an exploratory research design, data was collected through in-depth interviews with a purposive sample of sixteen members engaged in the beach park development. Subsequently, thematic and inverted pyramid-based co-occurrence analysis was employed within a qualitative research approach. The findings unveil a reciprocal relationship between the sense of place and the co-creation experience, marked by a spiraling-up dynamic. The findings further indicate variations in participants’ sense of place and co-creation experiences, providing valuable insights for planners, environmental managers and policymakers aiming to utilize active community participation for sensible and sustainable place-making.

For the poor residents in Witsand, an informal settlement on the periphery of Cape Town, electricity access is an everyday struggle, where households circumvent Eskom's vouchers and prepaid meters to adapt electricity to their lived realities. In this paper, we argue that in a context where Eskom electricity provision is often exclusionary, residents deploy diverse strategies to challenge this form of infrastructure violence. Drawing on over twenty months of ethnographic work, complemented with participant observations and semi-structured interviews, we demonstrate how resident-made electricity connections prove a critical and implicit part of the electricity infrastructure system. Building from a sociotechnical approach to infrastructure, we use the notion of ‘precarious power’ to explore the mix of agency and precariousness that are entangled in the everyday practices of ordinary people making electricity connections. We highlight that in improvising electricity access, residents in Witsand exercised their agency to circumvent and appropriate Eskom electricity. This paper contributes to an understanding of urban residents' everyday infrastructural experiences through an analytical frame that is neither dismissive of their agency nor celebratory of their struggles.

Against the backdrop of rapid global urbanization, the expansion of urban-rural spaces has led to conflicts among production-living-ecological spaces, resulting in a progressive decline in global ecological well-being. Coordinating spatial conflicts to minimize the reduction in ecological well-being is a critical scientific issue urgently needing resolution in current national spatial planning. In fact, the existing studies concentrates on the mechanisms, conceptual implications, evolutionary processes, and optimization simulations of historical spatial conflicts, yielding significant achievements. However, spatial conflicts are irreversible. Compared to studying historical spatial conflicts, assessing spatial conflicts risk which refer to potential occurrence of future spatial conflicts can provide more direct and robust support for optimizing territorial spatial planning. Unfortunately, there is a lack of research on the theory and methods of spatial conflicts risk assessment to date. To fill this gap, take the Production-Living-Ecological (PLE) spaces as a case study, social-ecological system framework (advance in deconstructing complex systems) and the land use function theory (advance in spatial quantification) have been combined to systematically construct a comprehensive framework and method for assessing PLE spatial conflicts risk. This newly framework analyzes the formation mechanism of conflicts risk from the dimensions of spatial pattern and governance. Furthermore, a quantitative and refined assessment method for PLE space conflicts risk at the raster scale is developed based on this framework, coupling coordination degree model, and multivariate data. The feasibility of this framework and method is validated through a case study of Zhangbei County, Hebei Province in China, a typical county in an ecologically fragile mountainous area. Moreover, we establish adaptive selection strategy to PLE space optimization under different governance scenarios based on the assessment result of PLE space conflicts risk. Findings of this research contribute new theoretical and methodological insights into addressing spatial conflicts issues while we are facing a more complex regional and urban system and fragmented governance. The case study will serve as a reference for counties in the northern mountainous area of Hebei Province and similar ecologically fragile mountain counties in planning and controlling coordinated and sustainable development of PLE space.

Across the Global South, many cities have forged sister city relationships with their peers across the world. In sub-Saharan Africa, the majority of sister city partnerships are with European and North American cities. The paper argues that although sister city partnerships have gained currency in southern cities, particularly sub-Saharan Africa, empirical evidence about their contribution to sustainable urban development remains patchy, thus needing attention. The paper further argues that the literature on North-South paradiplomacy involving emerging cities is lacking as scholarship on the subject is overly skewed in favour of the large and mega cities. Drawing mainly on qualitative interviews, observations, secondary data, and internet sources, the paper assessed the nature of North-South sister city partnerships and their contribution to sustainable development (SD) in emerging cities using the experience of Toledo-Tanga and Ieper-Wa sister city partnerships. The findings reveal that, the partnerships' initiatives in areas such as water and sanitation, education, healthcare, culture, environmental sustainability, recreation and local economic development align closely with specific SDG targets, illustrating how international municipal cooperation can contribute to the achievement of the global sustainability agenda. This alignment also underscores the relevance of the SDGs as a guiding framework for sister city partnerships. By pitching sister city partnerships against SD, the paper introduces an environmental dimension to the existing theoretical stance which only considers the cultural, social, and economic dimensions of sister city partnerships. Finally, the paper provides policy and practical recommendations for the promotion and application of sister city partnership as a strategy for achieving SD in the Global South.

Rapid urbanization increased human demand for natural resources, disrupting the balance between human and environment. This disruption led to regional environmental degradation, frequent natural disasters, and severe challenges in achieving sustainable development goals. In this context, fostering human and environment harmony is essential. However, research on quantifying their relationship and exploring the driving factors and mechanisms at a national fine spatial scale remains insufficient. This study endeavours to address this gap by constructing China's eco-environmental quality index (EQI) and human activity intensity (HAI) evaluation index systems with a 1 km resolution. Furthermore, the study utilizes the four-quadrant model and trend analysis to reveal the human-environment relationship, and employs the Bayesian network model to explore key drivers and underlying mechanisms influencing their relationship, aiming to foster harmonious human-environment interaction. Our results show that: (1) Both EQI and HAI increased over time, with their high values concentrated on the southeast side of the Hu Line but low on the northwest side. (2) The proportions of coordination and running-in areas increased while those of degradation and conflict areas declined, with 36.77% of the regions showing positive synergy during 2000–2020, indicating that China's human-environment relationship tended toward coordination. (3) Bayesian network analysis identified land use intensity, GDP, fraction vegetation coverage, and population density as critical factors affecting human-environment relationship. From a quadrant-based analysis, natural and eco-environmental factors including precipitation, water yield, and net primary productivity mainly influenced the spatial distribution of coordination and running-in intensity, while socioeconomic factors like population density and GDP primarily drove the spatial distribution of degradation and conflict intensity. This study finally proposed tailored management recommendations which would provide scientific support to facilitate the coordination and harmony of regional human-environment relationship.
快速城市化增加了人类对自然资源的需求，破坏了人类与环境之间的平衡。这种破坏导致区域环境退化，自然灾害频发，实现可持续发展目标面临严峻挑战。在这种情况下，促进人类与环境的和谐至关重要。然而，在国家精细空间尺度上量化二者关系并探索其驱动因素和机制的研究仍然不足。本研究通过构建中国 1 公里分辨率的生态环境质量指数（EQI）和人类活动强度（HAI）评价指标体系，努力填补这一空白。此外，本研究还利用四象限模型和趋势分析揭示了人类与环境的关系，并采用贝叶斯网络模型探讨了影响两者关系的关键驱动因素和内在机制，旨在促进人类与环境的和谐互动。我们的研究结果表明(1) 随着时间的推移，EQI 和 HAI 均有所上升，高值集中在沪线的东南侧，而低值则集中在西北侧。(2) 2000-2020 年间，协调区和磨合区的比例上升，退化区和冲突区的比例下降，有 36.77% 的区域呈现正协同，表明中国的人类与环境关系趋于协调。(3) 贝叶斯网络分析发现，土地利用强度、GDP、植被覆盖率和人口密度是影响人类与环境关系的关键因素。从基于象限的分析来看，降水量、产水量和净初级生产力等自然和生态环境因子主要影响协调和磨合强度的空间分布，而人口密度和 GDP 等社会经济因子主要驱动退化和冲突强度的空间分布。本研究最后提出了有针对性的管理建议，为促进区域人类与环境关系的协调与和谐提供了科学支持。

This paper focuses on unregulated development of planned urban areas, using the Laulane neighbourhood in Maputo, Mozambique as a case study. The neighbourhood was established in the 1980s via a simplified form of urban planning and subsequently developed without enforcement of planning regulations. The study combines quantitative and qualitative analysis of street and plot structures of the original plan and recent satellite imagery of the neighbourhood to investigate the long-term urban development dynamics. The findings highlight that the neighbourhood retained a high proportion of public space and high access porosity compared to recently studied unplanned settlements in the same city. As such, the study argues that minimal urban planning can enhance mobility and increase feasibility of investments in infrastructure even if subsequent development is unregulated by the state. With this background, the study discusses the mechanisms that made the plan successful despite the limited local institutional capacity, including community participation as well as establishment of adequate space for mobility systems and land reserves for future urban development. Finally, the study argues that such measures are increasingly relevant for supporting sustainable urban development in contexts characterized by rapid urbanisation and constrained state capacity to administer the urban development, particularly in sub-Saharan Africa.

Cultivated land protection plays a pivotal role in ensuring grain security. Although China has managed to halt the continuous decline in the total amount of cultivated land over the years, some of the complementary cultivated land is of poor quality. Therefore, China still needs to strengthen cultivated land protection by implementing cultivated land restoration (CLR). However, current studies on CLR have certain limitations, as they neglect the multidimensional perspective of cultivation suitability evaluation (CSE) and fail to prioritise specific types of secondary land for restoration. In this context, based on a theoretical analysis of the objects, connotations and objectives of CLR, focusing on the Chengdu Plain, China's primary grain-producing area, this study devised four CLR scenarios: the priority to sustainable use scenario (PSS), the priority to cost scenario (PCS), the priority to ecological health scenario (PES), and the comprehensive restoration scenario (CRS). These scenarios aimed to address three key questions about CLR: where to restore, what to restore, and how effective it is. The findings revealed that areas with high cultivation suitability values were located predominantly in flat regions with favourable natural conditions. Garden land and forest land emerged as the primary sources for CLR, with restored paddy field being more widely distributed, while restored irrigated land and dryland were concentrated in specific parts of the study area. Besides, the restoration of cultivated land led to a significant increase in grain production across all scenarios, with optimal resource allocation. Notably, the PSS scenario demonstrated the most promising results, resulting in a remarkable 59.20% increase in grain production. Therefore, we emphasise that the scientific CLR implementation is of great significance to cultivated land protection in China at this stage, and we advocate for conducting CSE and managing all potentially arable land (PAL) with a focus on sustainable use. Overall, this study offers valuable insights that can serve as a reference for other countries or regions facing similar challenges, such as limited per capita cultivated land and variations in land quality, regarding CLR and the sustainable management of agricultural land.

Clients' influence remains a significant issue in the property valuation industry, particularly in emerging countries like Nigeria, where existing solutions have proven ineffective. This study, therefore, considers blockchain technology as a medium for delivering information transparency and explores the application of a blockchain-based tool for reducing clients' influence in property valuation. Specifically, this study is pioneering in proposing, developing, and testing a blockchain-based solution for reducing client influence in property valuation, suggesting a promising avenue for increasing transparency in the process. This study involves several stages. Firstly, propchain, a blockchain-based mobile application, was developed and deployed on the Hyperledger Fabric Network, a permissioned blockchain network. The efficacy of the proposed solution was qualitatively tested by a single-round focus group held with valuers, bankers, and a loan customer who used the application to simulate a property valuation exercise for a mortgage. The findings suggest that blockchain technology could be a viable tool for reducing client influence in property valuations. However, specific challenges in the Nigerian context, such as data access, information verification, and stakeholder trust, present significant obstacles. These issues highlight the need for robust institutional support systems to enhance the efficacy of blockchain solutions in this domain. This study supports Levy and Schuck's (2005) assertion that increased information transparency can reduce client influence. Nevertheless, our research indicates that the successful implementation of blockchain in property valuation will require overcoming systemic barriers unique to the Nigerian environment.

客户的影响仍然是房地产估价行业的一个重要问题，尤其是在尼日利亚这样的新兴国家，现有的解决方案已被证明无效。因此，本研究将区块链技术视为提供信息透明度的媒介，并探索应用基于区块链的工具来减少客户对房地产估价的影响。具体而言，本研究开创性地提出、开发和测试了一种基于区块链的解决方案，以减少客户对物业估价的影响，为提高估价过程的透明度提供了一条大有可为的途径。这项研究涉及几个阶段。首先，在许可区块链网络 Hyperledger Fabric Network 上开发并部署了基于区块链的移动应用程序 propchain。通过与估价师、银行家和贷款客户进行单轮焦点小组讨论，对拟议解决方案的功效进行了定性测试。研究结果表明，区块链技术可以成为减少客户对房产估值影响的可行工具。然而，尼日利亚的具体挑战，如数据访问、信息验证和利益相关者的信任，带来了重大障碍。这些问题突出表明，需要强有力的制度支持系统来提高区块链解决方案在这一领域的效率。本研究支持 Levy 和 Schuck（2005 年）的观点，即增加信息透明度可以减少客户的影响。尽管如此，我们的研究表明，要在财产评估中成功实施区块链，就必须克服尼日利亚环境所特有的系统性障碍。本文还讨论了主要研究结果的影响。

This study, therefore, considers blockchain technology as a medium for delivering information transparency and explores the application of a blockchain-based tool for reducing clients' influence in property valuation. Specifically, this study is pioneering in proposing, developing, and testing a blockchain-based solution for reducing client influence in property valuation, suggesting a promising avenue for increasing transparency in the process. This study involves several stages. Firstly, <em>propchain</em>, a blockchain-based mobile application, was developed and deployed on the Hyperledger Fabric Network, a permissioned blockchain network. The efficacy of the proposed solution was qualitatively tested by a single-round focus group held with valuers, bankers, and a loan customer who used the application to simulate a property valuation exercise for a mortgage. The findings suggest that blockchain technology could be a viable tool for reducing client influence in property valuations. However, specific challenges in the Nigerian context, such as data access, information verification, and stakeholder trust, present significant obstacles. These issues highlight the need for robust institutional support systems to enhance the efficacy of blockchain solutions in this domain. This study supports Levy and Schuck's (2005) assertion that increased information transparency can reduce client influence. Nevertheless, our research indicates that the successful implementation of blockchain in property valuation will require overcoming systemic barriers unique to the Nigerian environment.

Simulating cultivated land changes is vital for improving decision-making in sustainable agriculture. Compared to previous studies, the Shared Socioeconomic Pathways and Representative Concentration Pathways (SSPs-RCPs) scenarios provide a comprehensive framework for integrating climate and socioeconomic factors, offering deeper insights into future cultivated land dynamics. Taking the Yangtze River Economic Belt (YREB) as the study area, we developed localized SSPs-RCPs scenarios and adopted Global Change Assessment Model (GCAM) and Future Land Use Simulation (FLUS) model to simulate cultivated land changes under multiple scenarios. The findings indicate that cultivated land is predicted to decrease under all scenarios, with the SSP1-2.6 and SSP3-7.0 scenarios showing the highest and lowest decrease of 39.24% and 8.32%, respectively. By 2050, the loss of cultivated land in the upper reaches is expected to be significantly greater than that in the middle and lower reaches. Furthermore, grasslands, forests, and urban areas are the main types of land that replacing cultivated land in the YREB. The hotspots of cultivated land loss are in mountainous areas such as Sichuan, Yunnan, and Guizhou. Additionally, the gravity center of cultivated land distribution moved along the southeast to northeast, with the center of gravity shifting from Guizhou to Hunan under scenarios SSP1-2.6 and SSP5-8.5. This study offers insights into the future development of cultivated land in the YREB and highlights the significance of implementing and improving policies for its protection.

COVID-19 has significantly affected the behavioural patterns of urban visitors. However, the non-linear relationships between visitor behaviour and built environments, particularly how these relationships have evolved during the pandemic, have not yet been extensively studied. Using over 10 million mobile big data records collected over three years in Fukuoka, Japan, incorporating the XGBoost machine learning model and SHAP-PDP interpretation method, we identified non-linear relationships between visitor behaviours and built environments. Our findings uncovered significant non-linear impacts on visitor behaviour of several urban characteristics, such as floor area ratio, building coverage ratio, road density, and POI richness. Notably, the floor area ratio exhibits a negative correlation with visit frequency below 1 but a positive correlation above 2. Building coverage ratio positively impacts visit frequency up to 1000 m2 per 10,000 m2, after which it turns negative; this correlation shifted towards a consistent negative trend during the pandemic. Road density, which usually correlates negatively with visit duration, became positively correlated above 700 m2 per 10,000 m2 during the pandemic. Similarly, the influence of floor area ratio on visit duration reversed from negative to positive under pandemic conditions. Revealing the dynamic and non-monotonic nature of how urban visitors respond to the built environment under the influence of the pandemic, our results provide valuable insights for urban planning strategies in response to crisis resiliently.
