Natural and man-made disasters have a significant impact on movement patterns, yet existing studies often focus on aggregate-level trends, overlooking the heterogeneity of mobility responses within and across communities. A critical gap remains in understanding the nuanced impacts of wildfires on localized, fine-scale human mobility patterns, particularly how factors such as proximity to the fire, socio-demographic characteristics, and infrastructure shape movement responses. In this paper, we address this gap by analyzing human movement patterns during the wildfire seasons from 2018 to 2020 in California Spatial analytics are used to examine movement flows around twelve wildfire events and map the evolution of their spatio-temporal patterns in response to these disruptive events. To quantify and assess the magnitude of changes in movement patterns between fire and non-fire years, we employ a structural similarity metric. In doing so, we identify the points of influence corresponding to the onset of the fire and the subsequent recovery period. Finally, we characterize variations between fire events and identify the wildfires that had the most significant impact on movement patterns. The findings demonstrate the complexity of movement responses to the wildfires, highlighting the intricate interactions between visitation patterns and the built environment.

The industrial spatial layout of agribusiness profoundly influences the modernisation transformation of agriculture in the post-industrial era. This study employs hot spot analysis and the density-based spatial clustering of applications with noise (DBSCAN) algorithm to investigate the spatial agglomeration patterns of agribusiness, then utilises co-location quotient and Apriori data mining algorithm to explore the spatial co-agglomeration rules of agribusiness. The results show that: (1) The Yangtze River Delta urban agglomeration forms a multi-centre, misaligned development pattern, along with a relatively specialised geographical division of labour at different stages of the agribusiness industrial chain, creating a hierarchical spatial structure of clusters. (2) The related industries within the agribusiness industrial chain present vertical integration paths with backward linkage characteristics, which strengthens the market dominance of the back-end industries. The distance between different industries within the agribusiness industrial chain constrains their spatial co-agglomeration. (3) Different cities have formed directional and heterogeneous rules of spatial co-agglomeration, leading to the emergence of four spatial co-agglomeration modes between agribusiness subdivision industries: the dual-engine mode driven by technology and market, the deeply integrated industrial chain mode, the market demand-driven mode, and the technology innovation-empowered mode.

Intercity passenger and freight transport on expressways reflect distinct socio-economic patterns. Understanding these differences is vital for urban network theory and regional development, but data limitations hinder vehicle type differentiation in past studies. Using Guangdong Province as a case study, we utilized expressway online toll collection data to create networks of passenger and freight flows, examining differences through network analysis and the Random Forest algorithm.The findings are summarized below. Passenger and freight flows largely adhere to a Pareto distribution. Passenger flow networks exhibit higher density and cohesion than freight networks. The lognormal function is the most suitable model for depicting the distance decay pattern of passenger flows, whereas the power function offers the best fit for freight flows. The range of passenger flows is concentrated within 0∼40 km, whereas the range for freight flows is 0∼100 km. From a spatial perspective, a notable spatial agglomeration effect is observed in passenger flows, which primarily concentrate along both sides of the Pearl River Estuary. Additionally, population factors exert a more substantial influence on passenger flows, whereas labor force and enterprise factors significantly impact freight flows. This study deepens our understanding of expressway transport and supports vehicle classification control and collaborative traffic governance.

Rewilding is an emerging strategy for biodiversity conservation. The 3Cs framework for rewilding involves three key components—core areas, corridors, and carnivores—of which the first two are related to space and land. By focusing on the Qinghai‒Tibet Plateau, we identified core areas and corridors, constructing a spatial network of wildlands on the basis of suitability assessment and ecological process simulation. The network accuracy was verified with biodiversity data, and policy suggestions were proposed according to land use analysis and related adjustment costs. The results show that wilderness suitability decreases from southeast to northwest. Large core areas are in the southeast, whereas corridors traverse the northwest, connecting relatively small, scattered, and wide core areas. Although the spatial network covers 25.69 % of the total area, 56.4 % of the carnivore records and 69.88 % of the mammal records are in this area. Most land types within the network are forests and grasslands; however, certain artificial surfaces and crop lands must be adjusted to enhance connectivity. Considering the adjustment costs, nonecological lands within corridors should be prioritized for transformation. We suggest a strategy that considers the quantity, scale, and distribution of the core areas, in addition to the adjustment of nonecological lands, to improve the ability of the spatial network to effectively conserve biodiversity.

This study examines environmental injustice in Italy through a distributive lens, focusing on contaminated areas designated as Sites of National Interest (SNIs). Using the spatial coincidence method and a composite indicator based on the Mazziotta-Pareto Index, we analyzed 2021 census data to explore the overlap between socio-demographic disadvantage and environmental contamination. By focusing on the legally defined boundaries of SNIs, this research enhances our understanding of how environmental risk intersects with population vulnerability profiles. Our results reveal that SNI areas tend to have higher levels of socio-demographic disadvantage than non-SNI areas, although there is considerable variability across SNIs, reflecting differences in historical, geographical and socio-economic contexts. The components of disadvantage are multifaceted, and no clear, easily interpretable pattern emerges across all SNIs. These findings provide a critical reflection on the theoretical and methodological frameworks used in environmental justice research in Italy. We argue for moving beyond a purely distributive approach to investigate the mechanisms and processes underlying the disproportionate exposure of vulnerable communities to environmental hazards. Additionally, we highlight the importance of complementing national-level studies with localized case studies to better capture the specific dynamics of environmental injustice.

Although the new energy vehicle (NEV) industry is providing new impetus for China's regional development, a deeper understanding of its conditions and processes remains imperative. This study extends path creation theory from evolutionary economic geography to explore the enabling environment for both path creation and subsequent path development. Challenging the conventional thinking that view the emergence industry as a new path, this study posits that the NEV sector's development is shaped by the dynamic interplay of multiple paths, including the headquarter, three-power, and vehicle assembly path. The inter-path interactions drive the industry transform through different development phases. Accordingly, this study proposes a framework comprising three-phase path transformation (selection, competition, and integration) and five-component enabling environment (strategic resources, industrial base, innovation environment, market competition, and institutional support). Empirical results, based on the Lotka-Volterra model and fixed effects models, show that: (1) enabling environment for path transformation varies across paths and phases; (2) while industrial base initiate path selection, its influence diminishes in later transformation phases; (3) vehicle assembly path exhibits dual technology-push and market-pull characteristics, while three-power path is policy-driven and subject to strategic resources. This finding suggests challenges for endogenous path development, as subsidies are phased out from 2023 onwards.

Private renting is generally considered to be the most precarious tenure. Migrants are generally seen as the disadvantaged cohorts in destination cities. However, to the best of our knowledge, few studies have constructed the Housing Precarity Index (HPI) and assessed its effect on the life satisfaction of migrant private renters. Here, using data from China as an exploratory case, this study develops a novel measure of housing precarity based on the 2019 Guangzhou Migrant Housing Survey dataset. This study combines five dwelling-based aspects of precarity: perceived tenure security, housing affordability, housing quality, access to public services, and commuting. This study observes a negative association between housing precarity and life satisfaction among migrant private renters. Moreover, spatial heterogeneity could act as a moderating variable, strengthening the negative association between housing precarity and life satisfaction. This study advances the importance of considering the housing precarity concept in understanding the life satisfaction of migrant private renters. More importantly, this study wants to amplify the voices of migrant workers in the private rented sector, as they are the most likely to suffer from housing precarity in destination cities but are not salient in academic and policy debates on housing.

Wine is often portrayed and perceived as a natural product; however, in fact, it's predominantly a highly industrialized, processed commodity. The vast majority of vine is cultivated in monocultural systems, requiring the intensive use of pesticides and agricultural machinery. Advanced cellar technologies and oenological practices standardize vinification, controlling and manipulating microbial and biochemical processes to ensure a uniform product. This approach has faced criticism, primarily due to its ecological implications. In response, a niche market has developed around so-called ‘natural’ or ‘low-intervention’ wines, emphasizing environmentally conscious production methods, resulting in a distinctive product. In a qualitative research approach, we explore the alternative practices which reflect the winemaker's care for soil and plant health, support microorganisms in the must, and preserve the wine's ingrediencies. Through practices like no-till, soil fertilization, and spontaneous fermentation, low-intervention winemakers aspire to stop soil degradation, regenerate their plants' microbiome and respect the grape's indigenous fermentation capacity, allowing in-situ yeasts to do their job and craft an individual wine flavour. Our article proposes a framework to explore these practices and the underlying philosophy, where the observed processes and winemaker's attitudes reflect an approach of ‘co-producing with nature’, which we explore by adopting conceptual ideas from more-than-human geographies.

葡萄酒通常被描绘成一种天然产品，但事实上，它主要是一种高度工业化的加工商品。绝大多数葡萄树都是单一栽培，需要大量使用杀虫剂和农业机械。先进的酒窖技术和酿酒方法使葡萄酒酿造标准化，控制和操纵微生物和生化过程，以确保产品的统一性。这种方法受到了批评，主要是由于其对生态的影响。作为回应，围绕所谓的 "天然 "或 "低干预 "葡萄酒形成了一个利基市场，强调环保的生产方法，从而产生了与众不同的产品。通过定性研究方法，我们探索了反映酿酒师对土壤和植物健康的关注、支持葡萄汁中的微生物以及保护葡萄酒成分的其他做法。通过免耕、土壤施肥和自发发酵等做法，低干预酿酒师希望阻止土壤退化，使植物的微生物群再生，并尊重葡萄的本土发酵能力，让原地酵母发挥其作用，酿造出独具特色的葡萄酒。我们的文章提出了一个框架来探讨这些实践和基本理念，其中观察到的过程和酿酒师的态度反映了一种 "与自然共同生产 "的方法，我们通过采用 "非人类地理 "的概念来探讨这种方法。

The uneven distribution of healthcare resources has emerged as a prominent concern in healthy city development globally. However, extant research mainly follows an amenity approach that merely regards hospitals as passive spatial carriers of healthcare services and rarely considers them as an integral part of the urbanization processes, overlooking the interactive relation between hospitals and urbanization and their implications for the supply-side healthcare inequalities. This study introduces a hospital-city nexus framework highlighting hospitals as crucial infrastructure for urban development, and incorporates open big data and statistical data to examine the interactive relationship between hospital clustering and urban structures across 36 major Chinese cities. The study identifies prevalent hospital clustering in China, characterized by specific morphology, land use, and institutional composition. Higher hospital clustering occurs in cities with low financial capacity, low per capita income, and advanced medical technologies. Land use and locational attributes are key factors in hospital clustering, while transport services play a lesser role. Hospital clustering is positively associated with nearby housing values, but the relationship with population density and aging are diverse. Highlighting the hospital-city nexus, this study enhances the supply-side understanding of the uneven spatial distribution of hospitals, informing relevant healthcare policy and urban planning.

Urban parks play a vital role in improving the urban ecological environment and promoting residents' physical and mental well-being. This study investigates the factors influencing visits to nature parks, comprehensive parks, community parks, and special parks in Beijing's central urban area while also examining spatial variations in these effects. An indicator system for park characteristics is developed, encompassing three dimensions: landscape attributes, accessibility, and surrounding environmental conditions. Mobile signal data are used to accurately quantify daily park visits. XGBoost and SHAP are then applied to analyze the importance of factors and the pathways through which they influence visitor flow. The findings highlight several key insights: (1) Parks in Beijing's urban area are densely distributed in central regions but sparsely distributed in peripheral areas; (2) comprehensive parks attract the highest number of visits, whereas community parks receive fewer visitors; (3) population density and public service facilities have the greatest impact on park visitation; and (4) park features exert nonlinear effects on visitation, with threshold effects observed. These findings provide valuable insights for park planning strategies aimed at increasing overall utilization rates.
