Dachaihu is the largest centralized migrant resettlement area in China, resulting from the early reservoir migration that occurred after the founding of New China due to the construction of the Danjiangkou Water Conservancy Project. The quality of life for villagers in migrant areas has improved due to the rapid development of society since the reform and opening up, of the “Beautiful Countryside Construction” and the “Rural Revitalization Project.” However, the subsequent changes in physical space, combined with the issues of rural depopulation and aging, present the area with dual challenges: a decline in collective memory and the deterioration of public space. Starting from collective memory, this study draws an emotional map from the interaction between elements of spiritual memory and material spatial places, analyzes the developmental changes and inter-generational differences between collective memory and public space through field research in three sample villages of the Dachaihu migrant resettlement area in Zhongxiang City. And from the support of rural public space to the spiritual culture and behavioral activities of villagers, it put forward the strategy of building public space with collective memory as a breakthrough, and put forward the goals of reconstructing collective memory and reviving rural public space for the construction of resettlement areas under the influence of major social and historical projects.

Land multifunctionality usually triggers conflicts over land-use spaces. To resolve this conflict, the concept of a production–living–ecological (PLE) space was introduced into regional land management and spatial planning. However, owing to the multifunctional demand for land in megacities, accurate identification of PLE spaces and the tradeoff relationship between them remain unclear. Using Guangzhou as an example, we constructed an assessment system from the perspective of land functional values to accurate identify PLE spaces from 2008 to 2023. The relationships, strengths, and influences of PLE tradeoffs or synergies were examined using Spearman’s correlation coefficient, root mean square error (RMSE), and multiscale geographically weighted regression (MGWR) models. The dominant functional type in Guangzhou was ecological space, followed by living space, and then production space. More than 90% of the land has double or triple land functions, highlighting the multifunctional characteristics of land use in Guangzhou. There was a synergistic relationship between the production and living functions (P–L). The highly synergistic area was centered in the urban core and gradually expanded to the northwest and southeast. There was a tradeoff relationship between the production function and ecological function (P–E), ecological function, and living function (E–L). Both had significant spatial heterogeneity in the spatial and temporal pattern distributions. Social and economic factors had a significant impact on the synergy intensity of the P–L function, whereas natural factors had a greater impact on the tradeoff intensity of the P–E function. The findings have provided empirical examples for optimizing land spatial patterns in urban or agglomerated areas and reconciling multifunctional land conflict relationships.

This study examines the factors influencing environmental migrants’ habitat preferences in southwestern Bangladesh. Using a multi-stage sampling technique, we selected 408 households in rural and urban areas, who had moved to their current locations due to climatic extremes. We applied relevant regression models to analyze the complex interplay of socioeconomic, environmental, and institutional factors shaping migration decisions. Our empirical results suggest that, despite having greater access to services in cities, migrants reported lower levels of well-being than their rural counterparts, which could be attributed to reduced social cohesion and limited opportunities for participation in decision-making. Disaster preparedness, early warning access, and prolonged exposure to environmental hazards significantly influence migration decisions and well-being. Protracted post-disaster suffering increases the likelihood of migration to urban slums, emphasizing the vulnerability of rural populations. Men are more likely than women to migrate to urban areas, possibly due to perceived employment opportunities. Surprisingly, while slum dwellers have better service access, their well-being scores are lower than rural residents. Access to education, healthcare, safe drinking water, and early warning systems are all crucial determinants of well-being. Policy recommendations include improving disaster preparedness and early warning systems in rural areas, developing targeted interventions for urban slum migrants focused on social cohesion and income diversification, and implementing gender-specific support programs. This research contributes to understanding environmental migration dynamics in Bangladesh and informs policymakers about sustainable resettlement strategies. Future studies should explore non-linear relationships and expand to diverse geographical contexts.

Farmland plays a vital role in regional food security and sustainable development. However, traditional farming practices primarily focus on grain production, neglecting the multifunctionality of farmland, which can lead to increased pollution and carbon emissions. This study investigates the impact of multifunctional farmland use transition (MFFUT) on synergistic governance efficiency for pollution reduction, carbon mitigation, and production increase in the Huang-Huai-Hai Plain (HHHP) from 2000 to 2020. Using econometric models, including the SSA-PPM model, super-efficiency SBM-DEA model, panel quantile model, and threshold regression model, the study evaluates the effectiveness of MFFUT in achieving synergistic governance. The results show that: 1) MFFUT is in an upward trend in MFFUT over the two decades, significantly enhancing the synergistic governance efficiency of pollution reduction, carbon mitigation, and production increase; 2) The positive impact of MFFUT on synergistic governance efficiency varies among different Major Function-oriented Zones (MFZs) and different efficiency levels, with higher quantiles showing more significant improvements; 3) Industrial structure serves as a crucial threshold, affecting the relationship between MFFUT and synergistic governance efficiency. This study stresses the balance of grain production expansion with environmental conservation through MFFUT. It contributes to a deeper understanding of MFFUT's role in sustainable agriculture, providing valuable insights for policymakers to support rational farmland resource utilisation and promote sustainable agricultural development.

The mechanism through which New-type Urbanization (NU), as a new direction in urban development, influences the Sustainable Development Goals (SDGs) by regulating the Ecosystem Services (ES) supply and demand remains to be determined. It is particularly true in urban agglomerations around lakes, characterized by severe human-land conflicts, where socio-economic development is closely linked to water. We selected China's urban agglomerations around lakes as the study area. We investigated the spatio-temporal heterogeneity of NU and the Ecosystem Service Supply and Demand Ratio (ESDR) from 2000 to 2018. We specifically focused on the dynamic trends of SDG 2 (Zero Hunger), SDG 13 (Climate Action), and SDG 15 (Life on Land). Furthermore, we utilized Structural Equation Modeling (SEM) to reveal the direct effects and indirect pathways through which NU influences the achievement of SDGs in the study area, emphasizing the differentiated performance of this mechanism across various urban agglomerations around Lakes. The results indicated that the ESDR has a particularly evident downward trend in urban centers along lakes, rivers, and road networks in spatial terms. The level of NU in urban agglomerations around lakes has increased by about 50% overall. It geographically exhibits three main spatial distribution patterns: “diffusion along the lake,” “homogeneous distribution,” and “diffusion along the river.” NU directly inhibits the achievement of SDGs but indirectly promotes the improvement of ESDR for food production and soil conservation, thereby indirectly facilitating the achievement of SDG 2 and SDG 15, but has an inhibitory effect on SDG 13. By regulating ESDR, NU is most effective in achieving SDGs in the urban agglomerations around Poyang Lake and Dongting Lake but has a significant inhibitory effect on the urban agglomeration around Hongze Lake. This research provides quantitative evidence for the urban planning shift, terrestrial ecosystem function restoration, and SDGs achievement in urban agglomerations around lakes. It also offers new insights from China for the sustainable urban construction of urban agglomerations around lakes worldwide.

As the World Health Organization launched its age-friendly city and communities programme nearly two decades ago, it raises concerns how to measure and evaluate urban policies concerning age-friendliness. This work presents the translation, validation and results of survey research for the older population of two age-friendly Polish cities (Kraków and Wrocław), using the Age-Friendly Cities and Communities Questionnaire. The study was conducted with two representative samples of older people living in Kraków (n = 392) and Wrocław (n = 409), who were asked to rate the age-friendliness of their cities. Based on the cluster analysis three typologies of older people emerged, reflecting the different views on their experience of living in the city. These resulting typologies showed that people's socio-economic status, living arrangements and health situation play an important role in how they experience city life. Results highlight the value of quantitative city evaluation in order to design and better monitor urban policies following an age-friendly agenda. The most important findings of particular relevance to public age-friendly policy in Poland is to secure the need for the older person to receive assistance with daily activities and mobility especially among those who do not see the positive aspects of living in an age-friendly city.

With the rapid growth of global urbanization, rural land has been continuously occupied, which has brought about profound changes in human-land relationship. As a rural regional system in the frontier area of urbanization, the rural settlements in the urban-rural integration area (URIA) are in a profound transformation due to multiple disturbances such as internal natural factors and social and economic factors brought about by external urbanization. Based on the internal and external system factors of rural settlements, this paper constructs an analytical framework to explore the spatial and temporal evolution pattern of URIA rural settlements from 2000 to 2020, and then summarizes its evolution model, and predicts the situation of rural settlements in different scenarios in 2030. Finally, the optimal control strategy is proposed. The results show that: (1) From 2000 to 2020, affected by the gradient of natural environment, the scale of rural settlements in URIA shows a trend of decreasing in low-altitude areas near rivers and increasing in high-altitude areas far from rivers. Under the socio-economic gradient, there is a phenomenon that the scale of rural settlements in the inner edge of URIA with better socio-economic environment decreases and the scale of settlements in the outer area of URIA with poor socio-economic environment increases. (2) Based on different environmental factors, in the internal natural environment, it shows the evolution mode of “terrain containment” and “water source guidance”, while in the socio-economic environment, it shows the evolution mode of “urban sprawl encroaches rural”, “population decrease and land increase”. (3) The simulation results of rural settlements in 2030 show that the scale of rural settlements in the periphery of URIA continues to increase under the natural development (ND) scenario, while the scale of rural settlements in the inner edge decreases and the distribution is scattered. Under the urban-rural integration development (URD) scenario, rural settlements are mainly concentrated in the core area of URIA, and the area of rural settlements turning into urban land has dropped significantly. (4) Based on different gradients, the settlements are divided into three types: centralized development type, restricted development type and migration remediation type. Patch reconstruction is carried out by gravity model, which can theoretically save land and vacate 327 hm2 of construction land index. Compared with the extensive development model of the ND scenario, the URD scenario has important theoretical significance in limiting the blind expansion of the city and realizing the integration of urban and rural development in Lanbai.

This paper rethinks participation in slum upgrading beyond a well-established dichotomy of “top-down” and “bottom-up” processes and instead proposes a relational and strategic approach to urban transformation. Based on qualitative research with a small informal settlement, Barrio Saldías, in Buenos Aires, that fell off the city government's agenda, this paper explores the role of participation in promoting upgrading from the margins. It argues that Saldías differs from instances of community-led upgrading due to the central role of party brokers and political representatives (especially from the local state) alongside residents, all of whom participate together in a political climate dominated by the discourses of citizen participation and slum upgrading. Rather than collapsing these experiences into the logic of clientelism, participation is centred as the articulatory logic based on a shared desire and commitment to transforming urban space, towards multiple political ends. Participatory upgrading in Saldías exceeds the narrow focus of project-centric approaches and draws on a wider trajectory of participation in Buenos Aires. It demonstrates this through an analysis of three moments of participatory upgrading in Saldías.

Based on qualitative research with a small informal settlement, Barrio Saldías, in Buenos Aires, that fell off the city government's agenda, this paper explores the role of participation in promoting upgrading from the margins. It argues that Saldías differs from instances of community-led upgrading due to the central role of party brokers and political representatives (especially from the local state) alongside residents, all of whom participate together in a political climate dominated by the discourses of citizen participation and slum upgrading. Rather than collapsing these experiences into the logic of clientelism, participation is centred as the articulatory logic based on a shared desire and commitment to transforming urban space, towards multiple political ends. Participatory upgrading in Saldías exceeds the narrow focus of project-centric approaches and draws on a wider trajectory of <em>participation</em> in Buenos Aires. It demonstrates this through an analysis of three moments of participatory upgrading in Saldías.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"153 ","pages":"Article 103196"},"PeriodicalIF":6.5,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
