The making of a land patrimony for the benefit of religious missions is profoundly linked to territorial construction in the colonies but is rarely examined from the angle of ecclesiastical governmentality over the ceded lands. This analysis highlights three complementary processes for understanding the role of religious mission land heritage in territorial reconfigurations. First, this article examines the process of “land sanctuarization”, which materializes territorial anchoring through the crystallization of land rights granted to religious missions over customary lands previously presumed to be “vacant”. Next, it explores the formation of an “ecclesiastical dominium”, manifested in the dismantling of state missions and their free transfer, explicit or tacit, to religious missions under concession or agreement regimes. This reveals the exercise of state power over the land heritage of religious missions, positioning them as structuring axes and administrative intermediaries for public services, thus giving rise to an ecclesiastical governmentality that drives territorial production and reconfiguration. Finally, postcolonial dynamics reveal the resurgence of new spatial polarities shaped by the complexity of evolving religious actors along the center–periphery axis of a recomposing territorialization. This study underscores the importance of a transversal approach to better govern the land legacies of religious missions, fostering a pluralistic reterritorialization of postcolonial societies in central Africa.

In high-density and land-scarce urban environments such as Taipei—a typical example of compact development in East Asia—informal green spaces (IGSs)—defined as unmanaged or unplanned vegetated urban areas such as vacant lots, street verges, and railway margins—play a growing role in urban environmental and social dynamics. This study explores residents’ perceptions of IGSs and examines how these spaces contribute to urban sustainability and land governance. Using a mixed-methods approach that combines the literature review, field observations, and a structured public opinion survey in Taipei’s Wenshan District, the study identifies key perceived benefits and drawbacks of IGSs. Findings show that residents highly value IGSs for enhancing urban greenery, offering recreational opportunities, and promoting physical and mental health. However, concerns persist regarding safety, sanitation, and maintenance—particularly fears of waste accumulation, mosquito breeding, and risks to children. The results highlight the dual nature of IGSs as both vital ecological assets and potential sources of urban disorder. These insights underscore the need for inclusive, community-based governance models that can transform IGSs into legitimate components of green infrastructure. The study contributes to emerging discussions on adaptive urban land governance by proposing that informal spaces be strategically integrated into urban planning frameworks to enhance environmental equity, resilience, and citizen well-being.

Urbanization is one of the most important challenges contributing to the trend of replacing agricultural land with high-value land uses, such as housing, as well as industrial and commercial activities, as a result of significant population growth. To face these challenges and improve urban sustainability, integrating an embedded concept of spatial planning, taking into account urban and peri-urban agriculture, will contribute to mitigating food security issues and the negative impact of climate change, while improving social and economic development. This project aims to analyze land use/cover changes in the Casablanca metropolitan area and its surrounding cities, which are undergoing rapid urban growth. To achieve this, time series of remote sensing data were analyzed in order to investigate the spatio-temporal changes in LU/LC and to evaluate the dynamics and spatial pattern of the city’s expansion over the past three decades, which has come at the expense of agricultural land. The study will also examine the relationship between urbanization and agricultural land use change over time. The results of this study show that Casablanca and its outskirts experience significant urban expansion and a decline in arable lands, with rates of 45% and 42%, respectively. The analysis of SDG indicator 11.3.1 has also shown that land consumption in the provinces of Mediouna, Mohammadia, and Nouaceur has exceeded population growth, due to rapid, uncontrolled urbanization at the expense of agricultural land, which highlights the need to develop a new conceptual framework for regenerating land systems based on the implementation of urban and peri-urban agriculture in vacant sites within urban and peri-urban areas. This will offer valuable insights for policymakers to investigate measures that can ensure sustainable land use planning strategies that effectively integrate agriculture into urban development.

Urban vacant land can provide important habitat for birds, especially in cities with high concentrations of residential vacancy. Understanding which vegetation features best support urban biodiversity can inform greening strategies that benefit both wildlife and residents. This study addressed two questions: (1) How does bird species composition reflect the potential conservation value of these neighborhoods? (2) Which vegetation structures predict bird abundance across a fine-grained urban landscape? To answer these questions, we conducted avian and vegetation surveys across 100 one-hectare plots in St. Louis, Missouri, USA. These surveys showed that species richness was positively associated with canopy cover (β = 0.32, p = 0.003). Canopy cover was also the strongest predictor of American Robin (Turdus migratorius) and Northern Cardinal (Cardinalis cardinalis) abundance (β = 1.9 for both species). In contrast, impervious surfaces and abandoned buildings were associated with generalist species. European Starling (Sturnus vulgaris) abundance was strongly and positively correlated with NMS Axis 1 (r = 0.878), while Chimney Swift (Chaetura pelagica) abundance was negatively correlated (r = −0.728). These findings underscore the significance of strategic habitat management in promoting urban biodiversity and addressing ecological challenges within urban landscapes. They also emphasize the importance of integrating biodiversity goals into urban planning policies to ensure sustainable and equitable development. Full article

Urban vacant land possesses significant yet untapped ecological potential (capacity to support biodiversity, ecological processes, and ecosystem functions) for enhancing urban sustainability and resilience. However, the absence of structured and adaptable frameworks for ecological assessment limits its effective integration into urban planning. This study introduces a novel multi-tier ecological assessment framework, combining expert-driven criteria established through the Fuzzy Delphi Method with GIS-based spatial analysis. The framework ensures flexibility and scalability, enabling planners to perform rapid preliminary assessments and progressively detailed evaluations depending on available resources and specific planning objectives. A case study in Sentul-Manjalara, Kuala Lumpur, demonstrates the framework’s practical application, resulting in an ecological potential map categorising vacant parcels into high, medium, and low revitalisation priorities. This approach effectively connects theoretical ecological insights and actionable urban planning, providing policymakers and planners with an evidence-based decision-making tool for strategically prioritising vacant land revitalisation efforts. The outcome enhances urban biodiversity, ecological connectivity, and long-term urban resilience. Full article

Urban densification threatens vacant lots in cities, potentially affecting biodiversity and the ecosystem services (ES) they provide. Policymakers require evidence-based tools to balance densification policies and initiatives with the preservation of green spaces. This research proposes a method to assess ecosystem conditions (EC) of vacant lots and combine it with ES demand in order to identify lots that need to be prioritised for preservation and restoration. This method is applied to the Northern Milan intermunicipal area (Italy). By using open-access satellite imagery, indicators for abiotic, biotic, and landscape characteristics were determined for each lot regarding four regulating ES (air purification, runoff mitigation, microclimate regulation, and pollination). The EC assessment provides planners with information on the ecosystems’ qualities and their ability to deliver ecosystem services. Our findings indicate that vacant lots differ in their contribution to ES provision due to variation in abiotic, biotic, and landscape connectivity conditions, underlining the need for a more detailed assessment of the differences between each individual area that composes the green infrastructure. However, challenges related to defining reference levels and the availability of detailed local data need to be addressed to guide planning decisions effectively. Full article

Urban voids, such as vacant lots, brownfields, fallow land, wasteland, and the spaces between buildings, have the potential to serve as habitats for a diverse range of plants. However, their value for plant conservation remains understudied because of their informal and neglected nature. The aim of this systematic review is to consider the potential for urban voids to contribute to urban plant biodiversity. A total of 55 studies from 14 countries were analysed for geographical trends, factors influencing plant biodiversity, research methods, and relevant environmental parameters. The results of this study show that the factors influencing the plant diversity of urban voids can be divided into three main categories: biophysical, temporal, and landscape factors. Biophysical factors, such as size, age, soil, and vegetation structure, as well as temporal factors, including site management and human interventions, are the most important at the site-level scale. In contrast, landscape factors, such as the location and distance from other green spaces, are more dominant at the larger urban scale. The review has identified a significant limitation in the available literature, with relatively few studies examining the influence of urban voids’ shape, ownership, and microclimate on biodiversity. With respect to research methods, the results suggest a recent increase in the use of GIS-based and remote sensing techniques to investigate the plant diversity of urban voids. The findings discussed in this paper indicate the need for further research to comprehensively understand the factors that promote urban vegetation diversity in urban voids. Full article

In Japan, vacant houses are widely recognized as a significant societal challenge. At the same time, the problems associated with vacant lots and land with unknown ownership are escalating and are expected to worsen in the future. In response, community organizations such as NPOs (nonprofit organizations), neighborhood associations, and government agencies have been central in increasing efforts toward effectively utilizing and managing these vacant properties. This study analyzed six cases supported by the MLIT (Ministry of Land, Infrastructure, Transport and Tourism) under the Land Bank initiative, with two cases involving land readjustment and four involving temporary use. A detailed examination of these pilot efforts and their application methods clearly highlights the necessity of integrating land management with urban planning. Furthermore, it has been found that there are several challenges in the Land Bank initiative, including difficulties in assessing market value, ownership issues, and the need for broad coordination. These findings provide important implications for improving Japan’s management of vacant land and houses. Full article

Urban greenspaces, such as parks and other public vegetated spaces, provide respite from the built environment for residents and visitors. Lesser-known urban greenspaces are community-managed open spaces (CMOSs), such as play lots, community gardens, and memorial gardens. This study investigated the effect of the distance to and size of parks and CMOSs on residential house prices in Baltimore, MD, in 2016–2017 using a hedonic price model. This is the first study of an urban city comparing parks and CMOSs. The study included 21,116 houses sold and revealed that park proximate price premiums ranged from 7.73% to 11.01% for distances of up to a 1/2 mile, and the CMOS proximate price premiums were 8.69% and 8.96% for distances of up to 1/8 and 1/4 miles, respectively. Moreover, both parks and CMOSs revealed a buyer preference of a 1/8 to 1/2 mile distance from these urban greenspaces. Small- to medium-sized parks, less than 9.65 acres, increased house prices by approximately 2.36%, and small CMOSs, less than 0.24 acres, increased house prices by 5.93%. These results confirm that parks and CMOSs provide economic benefits in addition to their social, health, and well-being benefits and suggest that CMOSs are a viable economic development strategy for communities.

The trend of gated communities is becoming the new alternative housing for the high-end residents of Jordan, reflecting global patterns of urbanisation. However, their emergence on the outskirts of Amman on vacant lands requires an early proactive planning approach to ensure their development in response to the growth of the surrounding areas, fostering an integrated urban fabric. This article examines whether gated communities contribute to urban discontinuity and lead to social segregation. The study employs a space syntax analysis on two cases in Amman to assess their integration, accessibility, and navigability to address the study’s key questions related to its integration, design implications, and spatial layout. Findings reveal significant spatial segregation, with low levels of integration and high step depth values, indicating potential challenges in navigation, connectivity, residents’ mobility, accessibility, and safety. The article suggests the importance of re-evaluating the design and planning approaches for these developments to promote organic townscape growth to ensure smooth integration with the surroundings.

Although urban greenspace enhances ecological functioning and human well-being through ecosystem services (ES), it is oftentimes inequitably distributed. Environmental justice (EJ) encompasses aspects of distributive, procedural, and interactive justice related to accessibility and allocation of environmental benefits. Vacant land in shrinking cities has the potential to address greenspace inequalities and provide ES. This study investigated the perceptions of residents regarding urban ES and EJ in their communities in St. Louis (MO, USA)—a shrinking city that was undergoing green development, through semi-structured interviews. Altogether, 27 residents were selected from socio-economically disadvantaged neighborhoods characterized by high levels of vacancy due to legacies of redlining and systemic racism. Interview analysis revealed four themes: green benefits (including recreation opportunities), green costs (e.g., concerns for increased crime and nuisance animals), injustice issues (e.g., access to community greenspaces), and changes in the community (e.g., higher property taxes). Results revealed that residents perceived ES as closely connected with EJ when it comes to urban greening projects in their city. This study helps inform the process of urban greening projects, particularly in shrinking cities at risk of inequities. Full article

This study uses time series regression models and dynamic panel models of five-class housing to investigate the dynamics of the housing price-vacancy relationship in Hong Kong, offering insights distinct from previous cross-sectional analyses that take new housing completions as a supply proxy, without considering vacant homes as a source of housing supply. Two major contributions emerge: first, the results support the hypothesis that housing vacancies exert a negative impact on housing prices, holding other factors constant. Second, new builds supply is found to have a positive effect on housing prices, which is in line with many previous studies, but it contradicts the prediction. The results challenge the use of land supply or new housing completions as the proxy of housing supply and put forward a novel suggestion of including vacant homes in the housing price analysis. Advanced approaches to collecting housing vacancy data are also discussed. These findings have significant implications for policymakers, urban planners, and real estate investors, providing valuable insights for crafting targeted interventions and informing investment decisions. This is one of the first time series and dynamic panel analyses of housing vacancy’s effect on prices. Full article

This study aims to enhance urban sustainability by analyzing the spatial distribution and underlying causes of vacant homes in Asan, Chungcheongnam-do. Various statistical methods were employed to analyze date concerning the number of vacant stores, population changes, land use complexity, and the physical characteristics of land and buildings; these factors were found to influence the prevalence of vacant homes across Asan. Additionally, it was found that distinct factors differentially affect specific regions, such as old downtown areas versus rural villages. This indicates that reducing vacant homes in these areas requires distinct policies tailored to the unique circumstances of each region. For instance, in old town areas, small lot ratios and land use complexity are significant, while in rural villages, the average number of floors and land use complexity play a major role. This study highlights the diverse factors influencing the prevalence of vacant homes and suggests that to effectively address this issue, policies should be developed that are tailored to the unique characteristics of each area, categorized at both the city and local levels.

Urbanization is one of the most visible symptoms of global changes. This process has been driven by the evolution of life on Earth, and it gradually modifies the structure of land use. Urban development is the most apparent indicator and measure of urbanization. The demand for vacant land and sustainable spatial development plans require new methods that support decision-making in the process of changing land use in suburban areas. The aim of this study was to describe a methodology for identifying and localizing urban development boundaries with the use of fuzzy set theory, to evaluate the degree of urbanization, and to analyze the dynamics of land-use changes in areas subjected to direct urbanization pressure with the use of photogrammetric data for 2005, 2010, 2017, and 2022. A case study was conducted in the Polish city of Olsztyn. The study’s results determined the degree of urbanization of the areas in the [0, 1] range, as well as the dynamics of change in each of the twenty-four adopted forms of land use. The results indicate that the proposed methods are useful for identifying the rate and direction of urbanization, and can be applied to optimize and counterbalance the development of settlements and infrastructure.
