Despite multiple efforts to formalise these settlements, obstacles remain due to fragmented governance structures, bureaucratic inefficiencies, and a misalignment between statutory land policy tools and the realities of informal land tenure. This paper examines the influence of land policy tools and formalisation instruments used to integrate informal settlements into the formal urban fabric, with a particular emphasis on Nigeria. Using a qualitative research approach, data were gathered through semi-structured interviews with 34 relevant stakeholders, including government officials, legal experts, community leaders, and urban planners. A thematic analysis was used to discover key themes and ideas. The findings suggest that previous land laws, particularly the Land Use Act of 1978, centralised land governance, making it difficult for low-income people to get formal titles. Formalisation mechanisms including Certificates of Occupancy, slum rehabilitation programs, and urban redevelopment initiatives have had minimal impact due to administrative delays and a lack of grassroots participation. The study also identifies key future strategies for improving formalisation outcomes, such as incorporating customary land practices into statutory systems, simplifying land titling procedures, leveraging technologies like Geographic Information System (GIS) and mobile data collection, and encouraging community-driven approaches. Finally, the study emphasises the importance of shifting away from rigid, top-down frameworks and towards inclusive, participative, and technologically enabled models that reflect local realities and promote long-term urban development.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"166 ","pages":"Article 103605"},"PeriodicalIF":7.0,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on an in-depth ethnographic case study of a historically significant Hakka village in Guangdong Province, the paper introduces the concepts of school-based ties (<em>xueyuan</em>) and village-based ties (<em>xiangyuan</em>) to examine how identity and community are co-produced through both functional practices and symbolic forms. Findings reveal that rural schools play a dual role: providing fundamental functions such as everyday care, educational access, and community interaction, while also serving as symbolic anchors for the community through spatial memory, ritual continuity, and intergenerational narratives. The analysis contributes to the interdisciplinary dialogues in rural resilience, infrastructural geographies, and cultural identity by conceptualising rural schools as dual-track infrastructures of belonging and meaning-making. It further challenges the efficiency-driven logic of school consolidation policies by foregrounding the emotional, symbolic, and relational functions of rural education. As rural settlements confront demographic decline and institutional withdrawal, sustaining such schools may prove pivotal to preserving the cultural fabric and future viability of rural life.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"166 ","pages":"Article 103610"},"PeriodicalIF":7.0,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate that HSE significantly enhances APC at both macro and micro levels. Regarding mechanisms, HSE exerts dual positive effects: On one hand, it effectively alleviates the liquidity constraints faced by supported households; on the other hand, it provides these households with convenient access to public services and employment opportunities, which helps reduce the uncertainties they encounter. All these positive effects enhance their APC. Heterogeneity analysis indicates that compared with HSE, which provides ownership-type indemnificatory housing, HSE, which provides rental-type indemnificatory housing, can more significantly enhance APC. Meanwhile, HSE demonstrates pronounced pro-poor traits. It has a more substantial enhancing effect on APC among low-income households and those living in economically underdeveloped regions. Moreover, GS plays an “inverted U-shaped” moderating role in the positive relationship between HSE and APC, particularly evident in China's central and western regions. The conclusions drawn from this study are conducive to a deeper understanding of the relationships among HSE, GS, and APC. Moreover, they offer a robust theoretical basis and ample empirical evidence to help developing countries more effectively optimize their housing security policies, taking the expansion of domestic demand as a strategic pivot, and devise relevant institutional reform plans.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"166 ","pages":"Article 103607"},"PeriodicalIF":7.0,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collecting precise demographic data at the village level is challenging because of the infrequency of population censuses and the limited accuracy of rural data derived from nighttime light and electricity consumption. This study addresses these challenges by utilizing a multisource data approach, including census data, nighttime light, and electricity consumption, to develop an index for assessing village outmigration, and further employs a gradient boosting decision tree (GBDT) model to investigate the major influencing factors and their nonlinear effects. An analysis of 339 villages in Suide County, Shaanxi Province, revealed substantial migration, with an average outmigration index value of 0.61. The spatial pattern of outmigration, which intensifies from central areas toward the peripheries, is closely aligned with major transportation routes, as validated by field research in representative villages. Transport accessibility to the county administrative center was also identified as a primary driver of the spatial distribution of outmigration, exhibiting a threshold effect and highlights the importance of transport accessibility in shaping rural demographics. Interpreted through the lens of push-pull theory, the study shows that outmigration is driven by a combination of “push” factors such as underdeveloped infrastructure and limited rural opportunities, and “pull” factors such as urban economic attraction and better access to services. Transport accessibility plays a pivotal role in mediating these forces. This novel methodology integrates multisource data to analyze population outmigration patterns and determinants in villages, offering insights into how sustainable rural development and rural revitalization can be achieved.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"166 ","pages":"Article 103602"},"PeriodicalIF":7.0,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses this challenge by developing a multidimensional scale-adjusted framework to evaluate 297 Chinese cities from 1990 to 2020 across five dimensions: Economy, Infrastructure, Environment, Healthcare, and Education. Using the Scale-Adjusted Metropolitan Indicators (SAMIs) derived from urban scaling models, which measure performance relative to city size expectations, we reveal growing tensions between economic growth and public service provision. The scaling exponents <em>β</em> of economic indicators rose from an average of 1.02 to1.23, reflecting stronger increasing returns to scale, while environmental and healthcare pressures persisted (<em>β</em> < 1). Economic SAMIs increasingly decoupled from those of education and healthcare, with correlations falling from 0.25 and 0.58 in 1990 to −0.03 and 0.13 in 2020. The Scale-Adjusted City Development Index (SCDI), a multidimensional composite metric, identifies two phases in China's regional disparity: differentiation (1990–2000) and rebalancing (2010–2020), with significant spatial and temporal dependencies. Case analyses demonstrate divergent development trajectories, including boom–bust cycles of resource-based cities and efficiency decline in mature coastal cities. This study contributes a generalizable framework integrating urban scaling theory with multidimensional diagnostics, offering a 30-year longitudinal assessment of interdimensional and regional imbalance with tailored policy recommendations.
