Although existing research has developed methods for accurately identifying urban functional areas, the crucial role of functional interdependencies, expressed through colocation, in shaping complex urban structures remains inadequately explored. To address this gap, this study proposes a methodological framework for calculating distance-based co-location quotients (DBCLQ) and constructing a colocation network to extract functional clusters. Empirical analysis in Beijing identifies typical colocation pairs and the distance intervals at which these relationships manifest. Asymmetric colocation relationships are observed, indicating that educational facilities, transportation services, and scenic facilities demonstrate a strong attraction to most nearby functions. The study also challenges universal applicability of distance decay in colocation analysis, showing that some colocation relationships are scale-specific, emerging only within particular distance thresholds. The colocation network of Beijing's functions reveals a complex, multi-layered urban functional fabric composed of interconnected and overlapping clusters. By classifying their morphology, clusters are categorized into four organizational patterns: central radial, linear, extensive area-wide, and dense nodal pattern, summarizing the common function types associated with different organizational patterns.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"163 ","pages":"Article 103474"},"PeriodicalIF":6.5,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291494","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}

Existing studies have largely overlooked the nonlinear feedback mechanisms and spatiotemporal dynamics underpinning rural settlements–farming interactions in mountainous contexts. To address this gap, this study integrates system dynamics modeling—with implementation in Vensim—and the entropy weight method for indicator weighting to evaluate the coupling coordination of the SFS in the mountainous areas of Chongqing within the TGRA. Through multi-scenario simulations, the research investigates how endogenous and exogenous drivers influence the evolution and optimization of the SFS over the period 2005–2020. The findings reveal that: ①Under the status quo development mode, the coupling coordination of the SFS in the TGRA exhibits a favorable trend, with an average annual growth rate of 2.5 % during 2005–2020. ②Endogenous dynamics, such as farmland utilization efficiency, mainly drive the coupling evolution of the SFS by enhancing land development in the reservoir area and responding to technological innovations and policy reforms. ③Exogenous dynamics, such as the degree of government expectation fulfillment, also influence the system by limiting excessive government interventions. However, endogenous dynamics have a significantly stronger effect than exogenous dynamics on the system's evolution. Therefore, it is essential to balance policy support with the improvement of endogenous dynamics to promote the region's sustainable development. This study contributes theoretical and methodological innovation by embedding dynamic feedback analysis into SFS evaluation and identifying key leverage points for rural revitalization. It also offers targeted policy recommendations to support the sustainable rural development of mountainous territorial systems, emphasizing a human–land systems perspective that aligns land structure optimization with ecological restoration and rural well-being.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"163 ","pages":"Article 103456"},"PeriodicalIF":6.5,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144288750","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 proposes an analytical framework for return migration decisions from a family perspective within rural tourism destinations. Based on face-to-face interviews with returnees in Guzhu Village, a typical tourism-oriented village in Zhejiang Province, we explore how evolving yet enduring family norms, particularly intergenerational and gender norms, shape the decision-making processes of rural laborers returning from urban to rural employment in the context of tourism development. By examining three distinct groups – younger generation without children, younger generation with dependent children, and older generation with children in adulthood – we identify how individuals at different stages of the family life cycle assume varying familial roles and adhere to different normative expectations. These distinctions significantly influence both their decisions to return and their roles in the development of rural tourism. We argue that family norms embedded in traditional Chinese culture must be considered in understanding individual return decisions, as they affect not only personal and family development dynamics but also have broader implications for rural communities through post-return employment choices.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"163 ","pages":"Article 103476"},"PeriodicalIF":6.5,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144264027","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}

To improve the efficiency of impervious surface optimization, this study integrates machine learning techniques to propose a multi-objective optimization model that considers the spatial characteristics of surrounding units. Firstly, spatial feature information of impervious surfaces around each geographic unit was extracted using a sliding window approach, based on three representative landscape pattern indices: area, shape, and aggregation. Subsequently, data on elevation, slope, water bodies, impervious surfaces, drainage outlet density, and flood points were incorporated to construct a robust flood risk assessment model using the Light Gradient Boosting Machine (LightGBM) algorithm. Finally, this model was coupled with the Non-dominated Sorting Genetic Algorithm 2 to optimize the spatial layout of impervious surfaces. The results show that: (1) LightGBM demonstrated higher accuracy and robustness in urban flood risk assessment compared to other machine learning algorithms; (2)while the total impervious surface area remained nearly unchanged, urban flood risk was reduced by 25.4 %, and the number of historical flood points in medium-high risk and above areas is reduced by 58.82 %.; (3) compared to pre-optimization, the area proportions of medium-risk, medium-high-risk, and extremely high-risk zones decreased by 35.19 %, 50.68 %, and 66.49 %, respectively.

In addition, it remains unclear whether this inequality-migration nexus will be mitigated or intensified by education. Thus, this paper will utilize the bilateral migration data from the Internal Revenue Service of the U.S. from 1990 to 2018 to investigate the migration-inequality nexus. One additional concern is the moderating effects of migrant educational background, which would be the fundamental indicator of migration intentions. Finally, this study finds that interstate migration can significantly positively affect income inequality. More specifically, such income inequality would be exacerbated in the destination states because skilled workers are more likely to move to seek higher wages compared to unskilled workers. This finding echoes the existing theory of Skill-biased Technological Change (SBTC).

Integrated Urban Water Management (IUWM) may enhance coordination between policies and actors, thereby establishing internal and external coherence for the efficient use of water resources, equitable and universal water distribution, and environmental conservation. However, studies on understanding urban water integration tend to focus on formal and structural forms without exploring informal processes as a broader perspective to achieve water sustainability. Meanwhile, non-prescribed, non-official rules and actions can be fundamental to overcoming fragmentation in urban water management. Therefore, this study explores informal mechanisms for pursuing an integrated approach to urban water management in Indonesia. Makassar is selected as a case study because of its variety of urban water issues and rich context of informal actions. The case offers lessons for other cities in Indonesia and beyond. We ask the following main questions: What informal actions facilitate internal and external integration in urban water management in Makassar, and how do these informal mechanisms affect Integrated Urban Water Management? The methodology comprises a qualitative content analysis to identify the mechanisms by analysing policy documents, reports, newspaper articles, social media, and previous studies. Semi-structured interviews with key stakeholders confirm and explain the content analysis results. The study finds that Makassar's IUWM approach extends beyond aligning formal mechanisms: informal processes determine water use conflicts, inadequate water access, and water scarcity. It is established that informal processes occur through <em>Tudang sipulung</em>, <em>Ngopi and Silaturahmi</em> for establishing conversation places, and <em>Dana bergulir and Gotong-royong</em> for fostering community contributions. This study argues that these conversations- and contribution-oriented informal mechanisms play an essential role in determining the success of integrated urban water management.
