Grid-scale battery energy storage systems (BESSs) are becoming central flexibility assets in electricity systems with rising renewable penetration, changing demand profiles, and increasing system security requirements. This review examines BESS development in Australia, Singapore, China, and New Zealand, comparing strategic policy drivers, market access arrangements, revenue mechanisms, bankability conditions, support instruments, regulatory frameworks, and key deployment risks. Across all four jurisdictions, BESSs are moving from demonstration assets to core infrastructure for renewable integration, frequency control, reserve provision, congestion management, and short-duration energy shifting. The comparison shows that no single business model dominates. Australia relies heavily on volatile wholesale arbitrage, ancillary services, and government underwriting; Singapore emphasises grid resilience, dispatch precision, safety, and space-efficient deployment; China combines national strategic direction with province-specific market implementation; and New Zealand is developing a market-led, location-specific storage model within a high-renewables, hydro-dominated system. The review finds that bankable BESS deployment depends on revenue stacking, fit-for-purpose market rules, clear bidirectional asset classification, robust grid-connection processes, lifecycle safety management, and credible degradation and augmentation strategies. It concludes that BESSs are essential but not sufficient for deep decarbonisation, since long-duration flexibility and wider system reform remain necessary. Full article

The deep integration of the digital economy and education is a critical pathway to addressing the common challenges in less-developed regions, such as human capital shortages, unequal public service provision, and low developmental inclusiveness during new-type urbanization. Using panel data from 11 prefecture-level cities in Jiangxi Province from 2017 to 2024, this study first constructs a comprehensive index system to measure the integration level of the digital economy and education, as well as the inclusive development level of new-type urbanization. The entropy method is employed for objective weighting and composite score calculation. The spatiotemporal patterns of these two variables are visualized using hot spot analysis. A spatial Durbin model (SDM) with dual fixed effects is then applied to empirically examine the direct effect, spatial spillover effects, and regional heterogeneity of the digital-education integration. The main findings are as follows: (1) Both the integration level of the digital economy and education and the inclusive development of new-type urbanization in Jiangxi Province exhibit a distinct spatial pattern characterized as “high in the north, low in the south, and weak in the central region”, with significant spatiotemporal coupling between the two. (2) The digital-education integration exerts a significant positive direct effect on the local inclusive development of new-type urbanization. The core transmission mechanisms are the inclusive sharing of digital educational resources and the effective enhancement of human capital. (3) The integration generates a positive, albeit relatively weak, spatial spillover effect on neighboring areas. The strength of this spillover effect shows pronounced regional heterogeneity, being strongest in Northern Jiangxi, followed by Southern Jiangxi, and weakest in Central Jiangxi. (4) Economic development and industrial upgrading synergistically drive inclusive development alongside the digital-education integration. However, unequal social security provision remains a significant inhibiting factor for inclusive development. Full article

This study investigates ecosystem service valuation on Zhoushan Island. Based on Landsat remote sensing images for 2000, 2010, and 2020 acquired through the Google Earth Engine (GEE) platform, six land use types are extracted using the Random Forest method. By integrating land use dynamic degree, transfer matrix, ecosystem service value (ESV) accounting, and five-level land–sea gradient zoning approaches, this study systematically analyzes the spatiotemporal evolution of land use and its effects on ESV over the 20-year period, and reveals the spatial differentiation pattern of land use change and ESV gains and losses along the land–sea gradient. The results indicate that from 2000 to 2020, water bodies and cultivated land on Zhoushan Island experienced continuous decline while construction land expanded rapidly, driven by policy regulation, urbanization, and industrial transformation. Localized coastal areas exhibited a typical chain conversion process of “water body → bare land → construction land,” which is closely associated with reclamation and land reclamation activities. Regional ESV declined continuously, reaching only 56.7% of its 2000 level by 2020, with regulating and provisioning services exhibiting the most pronounced deterioration. Analysis of the ESV net transfer matrix indicates that the primary driver of ESV decline was the large-scale conversion of high-value water bodies to low-value construction land and bare land, the magnitude of which far exceeded the positive ecological gains generated by all other land use conversions. The reduction in cultivated land area, compounded by adjustments in cropping structure, has placed sustained pressure on regional food security, and policy responses have lagged considerably behind the pace of ecological degradation. In terms of spatial differentiation, both the intensity of land use change and ESV loss exhibited a gradient pattern that decreases progressively from the coastal zone moving inland. Zone 1 and Zone 2 in the nearshore area together accounted for approximately 80% of total ESV loss, whereas Zone 4 and Zone 5 maintained relatively stable land use structures and ecological support capacity, owing to higher forestland coverage. Spearman’s rank correlation analysis confirmed a statistically significant monotonically decreasing relationship between land use dynamic degree and coastal distance. Policy regulation served as the primary driver of regional land use pattern evolution: early sea reclamation policies facilitated rapid land transformation along the coastline, while subsequent tightening of controls effectively curbed disorderly expansion.

In a large agrarian country with numerous smallholders, a key issue in food security governance is determining how to overcome the constraints of fragmented smallholder farming through productive service provision and thereby expand the scale of grain production. This study focuses on the pilot policy of whole-process socialized agricultural production services implemented during 2013–2016. This pilot served as an important policy foundation for the agricultural production trusteeship policy promoted nationwide after 2017 and represented an early institutional exploration of promoting service-scale operation through fiscal support for productive service provision in China. Using county-level panel data from three provinces over the period 2006–2016, this study evaluated the effect of fiscal subsidies embedded in outsourced service transactions on grain-sown area within a two-way fixed-effects framework with county and year fixed effects. The results show that the pilot significantly expanded the county-level grain-sown area, with the pilot counties increasing their grain-sown area by approximately 1.986 thousand hectares on average. When policy intensity is measured according to the amount of subsidies, each additional 10 million yuan of fiscal subsidies increased the grain-sown area by approximately 3.103 thousand hectares on average. Heterogeneity analysis shows that the marginal effects were stronger in counties with weaker fiscal capacity or lower levels of mechanization, indicating that the policy effects were more pronounced in areas with relatively weak initial conditions. In terms of policy implications, this paper recommends differentiated and performance-based support, improved governance of the agricultural service market, and prioritizing resource allocation to areas with weaker initial conditions, so as to enhance the scale and resilience of food security. This paper provides county-level quasi-causal evidence and an empirical reference for supporting agricultural productive services through fiscal policy to overcome the constraints of fragmented smallholder farming.

Bottom-up approaches to climate resilience are increasingly promoted, yet there remains a gap in understanding how science-society connections can be operationalized in everyday contexts to support adaptive land-use practices, particularly in small towns and peripheral regions. This paper addresses this gap by examining how Living Labs (LLs) can function as process-oriented interfaces between scientific knowledge, local experience, and participatory negotiation, rather than as instruments for producing novel biophysical and social-learning insights. Drawing on selected case studies from the Biodiversity Hub and the Department for Building and Environment at the University for Continuing Education Krems (Austria), the study applies a qualitative, transdisciplinary Living Lab approach combining regular shared site walks, emotional communication, and cross-sectoral ecosystem services assessment matrices (aligned with established classifications and quantitative data collection). Resilience is grounded in the literature as a social–ecological capacity for adaptation and transformation and is operationalized pragmatically as the strengthening of connectedness between people, place, and ecological processes. The key findings show that short, place-based, and experiential interactions—such as shared walks and co-creative ecosystem service assessments—can lower participation barriers, mitigate power asymmetries, and enable rapid integration of scientific perspectives into everyday land-use decision-making. Rather than producing directly replicable outcomes, Living Labs generate transferable process principles, including emotional correspondence, structured negotiation, and the use of simple boundary tools to support collective learning and action. The paper contributes to resilience and land-system research by demonstrating how Living Labs can enhance local adaptive capacity and climate resilience through process design, immediate feedback, and continuous experimentation. It thereby complements conventional, indicator-driven assessments by illustrating how resilience can be enacted through participatory, place-based governance practices, offering practical guidance for municipalities and regions facing climate-related risks such as heat stress, drought, soil degradation, biodiversity loss, and increasing pressures on the secure provision of food, materials, and drinking water.

Background: Although the application of smart home technology in the Chinese eldercare market is widespread, its effectiveness from the users’ perspective remains underexplored. This qualitative study examines the perceptions and experiences of older adult users in adopting and applying the Care-on-Call services (Ping An Tong; PAT), a prominent example of smart home technology for eldercare in Mainland China. Methods: Individual and dyadic interviews were conducted with 28 older adult users from diverse physical, socioeconomic, and familial backgrounds. Thematic analysis was performed. Results: Two overarching themes were illustrated based on thematic analysis. First, the multifaceted challenges of using PAT encompass an incomplete cognition of the services, unfamiliarity with PAT systems, psycho-cultural resistance, ‘do it yourself, don’t bother others’, economic concerns of additional costs, and ethical concerns regarding information security and privacy. Second, bridging the technology divide highlights the empowerment of PAT use among older adults through a variety of educational methods to effectively utilize the services, enhancing service effectiveness through the integration of smart home technology and social service provision, and increasing service accessibility through inclusive services. The disparities in smart home technology application between China and the West are also discussed. Conclusions: Psychosocial support, organizational programs, and the integrated service model are recommended to promote the utilization of smart home technology among older adults in China.

The administrative boundaries of ecosystems do not necessarily align with natural watershed boundaries, which is a significant reason for the current inefficiency and pronounced conflicts in ecological governance. Using the watershed as the fundamental unit, this study assessed the forest ecosystem services (FES) of the Beihai Wetland watershed in Tengchong (As of 2025). Forest vegetation was classified to the formation level, and the functional value method was employed. The results showed the following order of service values: regulating services > provisioning services > supporting services > cultural services. Biodiversity was identified as the most valuable ecosystem function. The study further revealed that factors such as stand type, stand age, and altitude influence the total FES value within the watershed. Analysis of FES per unit stand (1 ha) indicated that Lithocarpus variolosus Franch. Chun (natural forest) exhibited the highest value. Through in-depth analysis of linear correlations and spatial associations of FES per unit stand, a synergy-trade-off visualization was constructed. This revealed that natural forests in the upper watershed may exert systemic effects on nutrient cycling in the lower watershed. The results obtained at the formation level provide support for the development of watershed-based forest tending plans. Moreover, studying FES using the watershed as a unit represents a practical exploration of the “life community of mountains, rivers, forests, farmlands, lakes, grasslands, and deserts” and offers a potential reference for maintaining the ecological security and supporting the ecological protection and restoration of the Beihai watershed.

The rapid evolution of 6G networks and large-scale Internet of Things (IoT) deployments intensifies security and privacy challenges in embedded SIM (eSIM) Remote SIM Provisioning (RSP), particularly during the bootstrap and profile delivery phases. Traditional perimeter-based and VPN-centric approaches expose static attack surfaces, making provisioning workflows vulnerable to denial-of-service (DoS) attacks, reconnaissance, and profile lock-in risks. This paper presents MTD-SDP-eSIM, a hardware-anchored Zero Trust Architecture that secures eSIM provisioning by integrating the embedded Universal Integrated Circuit Card (eUICC) as a root of trust with Software-Defined Perimeter (SDP), Software-Defined Networking (SDN), and Moving Target Defense (MTD). The framework introduces Hardware-Anchored Single Packet Authorization (ES-SPA), which cryptographically binds initial access to tamper-resistant eUICC credentials and enforces an authenticate-before-connect model. A unified Zero Trust controller dynamically orchestrates SDP access control, SDN-based micro-segmentation, and MTD-driven Network Address Shuffling during high-risk provisioning phases. This framework is validated on a high-fidelity 6G testbed built using ns-3, Open5GS, and P4-programmable switches. Experimental results demonstrate a 90% DoS survival rate during provisioning, a 35% scalability improvement over VPN-based baselines, and a 75% reduction in profile lock-in failures through runtime deletion verification. These findings confirm that anchoring dynamic network defenses in hardware-rooted identity significantly enhances the resilience, scalability, and privacy of eSIM provisioning for massive 6G IoT deployments.

The rapid convergence of the Internet of Things (IoT) and decentralized finance (DeFi) is reshaping the digital economy by enabling autonomous, trustless, and value-driven interactions among connected devices. This paper provides a comprehensive survey of the emerging paradigm that combines IoT’s pervasive sensing and communication capabilities with DeFi’s programmable financial infrastructure. We first discuss the motivation behind this convergence and explore key opportunities, including autonomous machine-to-machine (M2M) payments, decentralized data marketplaces, and trustless IoT service provisioning. Despite its potential, IoT–DeFi integration introduces significant security and privacy challenges related to smart contract vulnerabilities, consensus protocol risks, oracle manipulation, and constrained device capabilities. We review existing mitigation approaches such as lightweight cryptography, secure contract design, and decentralized identity management, and critically assess their limitations in heterogeneous, resource-limited environments. Building on this analysis, identify research gaps and propose future directions emphasizing formal verification of IoT-integrated smart contracts, robust oracle design, interoperability frameworks, and privacy-preserving trust models. This survey systematically maps opportunities, threats, and open issues. In doing so, it guides researchers and practitioners toward building secure, scalable, and energy-efficient IoT–DeFi ecosystems for next-generation decentralized applications. Full article

As a populous country with limited per capita land area, China has implemented the strictest land use regulation to ensure food security. Yet quantitative assessments of how it shapes land use change and the subsequent economic impacts remain insufficient. Land use directly affects land supply for industry and services, thereby impacting local fiscal and tax revenues. Meanwhile, land transfer income serves as a major off-budget revenue source for local governments, with county fiscal capacity laying the foundation for national economic development and public welfare. Therefore, this study integrates county-level statistics with remotely sensed land use data and applies an Intensity Difference-in-Differences (Intensity DID) design to identify policy impacts. Specifically, it examines the effects of land use regulation on county governments’ land transfer activities, land use efficiency, as well as fiscal revenue and public service provision. Empirical results show that tighter land use regulation constrains the new supply of construction land by limiting cultivated land conversion. In response, local governments modify floor area ratios (FARs) and shorten construction cycles, which is conducive to improving land use efficiency. Nevertheless, the policy reduces the land transfer income, tax revenue, and general public budget revenue of county governments, weakening public service provision. Heterogeneity analysis indicates that major grain-producing counties are more severely affected by negative policy shocks than non-major ones. This study provides empirical evidence for optimizing the land use regulation system and offers policy implications for coordinating food security and balanced regional development through horizontal interest compensation in major grain-producing regions.

This study provides a comprehensive economic valuation of ecosystem services and environmental impacts across four major agroecosystems—wheat, barley, sugar beet, and coriander—under intensive management in the semi-arid Nahavand County, Iran. Soil properties, ecosystem service provision, and environmental disservices such as greenhouse gas emissions, soil erosion, and nutrient leaching were systematically assessed using field surveys, farmer questionnaires, and established ecological models. Coriander exhibited the highest net ecosystem service value, ranging from $115,840 to $154,750 ha⁻¹, driven by superior provisioning services (39.77% of total value) and the lowest environmental costs. In contrast, sugar beet presented the greatest ecological burden, with environmental costs exceeding $22,000 ha⁻¹, leading to the lowest net benefits ($51,940–$79,300 ha⁻¹). Nonlinear Gaussian regression models demonstrated strong predictive capacity (R = 0.91 to 0.99) for marketable value based on yield metrics, highlighting the importance of biomass productivity in economic valuation. These findings underscore the multifunctionality of coriander and emphasize the pivotal role of crop selection in optimizing agroecosystem sustainability, balancing food security, ecosystem health, and environmental conservation in semi-arid agricultural landscapes.

Volunteer tourism is garnering growing attention across various fields, allowing tourists to both consume and co-produce tourism services. In agriculture, however, this remains underexplored, despite a worsening farm labour shortage due to ageing populations and a lack of successors, particularly in industrialised nations. This issue threatens farm productivity and food security. This paper addresses this research gap by examining paid volunteer tourism platforms in Japan. It presents a framework highlighting the co-creation of local tourism demand and analyses wage determinants across 138 farms. Results show that corporate farms engaged in direct sales offer higher wages, especially when prices are elevated or locations are remote, suggesting wage premiums reflect labour shortages. Accommodation and Wi-Fi provision depend on farm finances and unused facilities. Organic and GAP-certified farms offer lower wages, likely due to higher production costs, despite producing value-added goods. As platform-based paid volunteer tourism meets the needs of both farmers and volunteers, its prevalence is expected to increase. Full article

The incorporation of artificial intelligence (AI) and digital technology in healthcare has revolutionized service delivery, improving diagnostic precision, patient outcomes, and operational efficacy. Nonetheless, despite considerable progress, numerous problems persist that impede the realization of full potential. Current reviews predominantly emphasize the advantages of AI in disease detection and health guidance, neglecting significant concerns such as social opposition, regulatory frameworks, and geographical discrepancies. This SLR, executed in accordance with PRISMA principles, examined 21 publications from 2020 to 2025 to assess the present condition of AI and digital technologies inside Saudi Arabia’s healthcare industry. Initially, 863 publications were obtained, from which 21 were chosen for comprehensive examination. Significant discoveries encompass the extensive utilization of telemedicine, data analytics, mobile health applications, Internet of Things, electronic health records, blockchain technology, online platforms, cloud computing, and encryption methods. These technologies augment diagnostic precision, boost patient outcomes, optimize administrative procedures, and foster preventative medicine, contributing to cost-effectiveness, environmental sustainability, and enduring service provision. Nonetheless, issues include data privacy concerns, elevated implementation expenses, opposition to change, interoperability challenge, and regulatory issues persist as substantial barriers. Subsequent investigations must concentrate on the development of culturally relevant AI algorithms, the enhancement of Arabic natural language processing, and the establishment of AI-driven mental health systems. By confronting these challenges and utilizing emerging technologies, Saudi Arabia has the potential to establish its status as a leading nation in medical services innovation, guaranteeing patient-centered, efficient, and accessible healthcare delivery. Recommendations must include augmenting data privacy and security, minimizing implementation expenses, surmounting resistance to change, enhancing interoperability, fortifying regulatory frameworks, addressing regional inequities, and investing in nascent technologies.

The evolution of landscape patterns in plateau lake basins directly influences the sustainable provision of ecosystem services. Revealing and predicting the impacts of landscape changes on ecosystem service value (ESV) under different development scenarios are essential for maintaining regional ecological security, enhancing ESV, and formulating policies for ecological conservation and restoration. As a typical representative of China’s plateau lake basin, the Erhai Lake Basin faces multiple challenges arising from rapid urbanization, tourism commercialization, and agricultural modernization. It is therefore crucial to understand its potential future landscape dynamics and their effects on ecosystem services. Based on landscape data, natural environmental data, and socio-economic data, we applied GIS-based spatial analysis and the equivalent factor method to simulate and assess landscape pattern changes and corresponding variations in ESV in 2030, 2040, and 2050 under three distinct scenarios. Local spatial autocorrelation analysis was further employed to identify the spatial clustering patterns of ESV. There were three findings: (1) From 2030 to 2050, forest increased continuously under the natural evolution scenario (NES) and ecological protection scenario (EPS) but declined under the economic growth scenario (EGS). Farmland expanded under the NES and EGS, whereas it decreased under the EPS. Grassland declined across all three scenarios, while built-up area showed consistent expansion. (2) In all simulated years, the total ESV of the Erhai Lake Basin ranked as EPS > NES > EGS. Between 2030 and 2050, total ESV exhibited an increasing trend under the EPS but declined under the other two scenarios, with the sharpest reduction under the EGS. Forests and water body were the main contributors to total ESV, while farmland and grassland played a critical role in driving ESV dynamics—the scale and direction of their transformation directly determined the overall ESV trends. (3) Across the three scenarios, ESVs all exhibit significant spatial heterogeneity. Local Moran’s I analysis indicated a dominant cluster of high values (HH) or a cluster of low values (LL), with LL clusters mainly concentrated in the northern basin and the western side of Erhai Lake, and HH clusters primarily located within the lake area. This study, through multi-scenario simulations, elucidates the spatiotemporal dynamics of landscape and ESV changes, providing valuable insights for green transformation, landscape spatial allocation, ecological restoration, and sustainable development in the Erhai Lake Basin.

Climate change and land-use intensification are speeding up the loss of ecosystem services that support human health, food security, and environmental stability. Vegetative interventions—such as urban forests in cities and cover crops in farming systems—are increasingly seen as nature-based solutions for climate adaptation. However, their benefits are often viewed separately. This review combines 20 years of research to explore how these strategies, together, improve provisioning, regulating, supporting, and cultural ecosystem services across various landscapes. Urban forests help reduce urban heat islands, improve air quality, manage stormwater, and offer cultural and health benefits. Cover crops increase soil fertility, regulate water, support nutrient cycling, and enhance crop yields, with potential for carbon sequestration and biofuel production. We identify opportunities and challenges, highlight barriers to adopting these strategies, and suggest integrated frameworks—including spatial decision-support tools, incentive programs, and education—to encourage broader use. By connecting urban and rural systems, this review underscores vegetation as a versatile tool for resilience, essential for reaching global sustainability goals. Full article
