Petrochemical port cities in China face the challenge of promoting industrial development and improving environmental quality. In this situation, this paper constructs a semantic ontology-based data model from the perspective of the overall classification of environmental factors to review the environmental quality of the last three years in seven major petrochemical port cities in China. The process includes three stages. Firstly, the information sources were identified, and the research team collected and screened 1858 related papers from Web of Science and the China National Knowledge Infrastructure according to the theme of the review. Secondly, the information preprocessing was carried out, and the selected literature was sorted and filtered according to different cities and environmental elements. Finally, the research team established semantic ontology data models for the atmosphere, water, soil, biology, and acoustics environment based on the preprocessed information through visualization analysis. By using these models, the research team analyzed the hotspots of pollutants and pollution sources research in different cities in various environmental domains and summarized the main pollution mitigation measures highlighted in the research. In this way, the systematic bias and structural problem of the existing environmental study were revealed. Based on the above results, the targeted governance strategies were proposed to provide theoretical support for promoting coordinated industrial and environmental development in China’s petrochemical port cities.

The Paraguayan spatial planning system is analyzed through its legal framework, institutional structure, and implementation mechanisms, placing it within the Latin American context marked by fragmented governance and institutional inequality. Based on a review of laws and planning instruments at the national, departmental, and municipal levels, this study examines the system’s evolution, with particular focus on the period from the consolidation of the constitutional framework to the formulation of recent policies promoting sustainable development, decentralization, and democratic decision-making. The findings show a process of partial institutionalization, where norms and methodologies advance more rapidly than operational and financial capacities, resulting in uneven implementation across regions. Ongoing challenges include regulatory fragmentation, overlapping responsibilities, and weak multilevel coordination. Enhancing institutional coherence, prioritizing planning instruments, and strengthening subnational technical capacities are key to achieving a coherent and equitable spatial planning system that integrates international cooperation and translates sustainability and equity principles into practical dimensions of territorial governance.

South Africa’s land reform program is a cornerstone of efforts to redress historical injustices, guided by the 1997 White Paper on Land Reform Policy and structured around restitution, redistribution, and tenure reform. Three decades into implementation, this study systematically reviews the policy performance from 1994 to 2024, focusing on these pillars and related governance measures. Despite repeated policy revisions and extensive public debate, significant gaps persist between objectives, such as equitable access, tenure security, and poverty reduction—and actual outcomes. Using PRISMA guidelines, 94 peer-reviewed articles were selected from Scopus (1994–2024) alongside key policy documents and official reports. Evidence shows that land reform has consistently fallen short of its targets. Restitution claims remain largely cash-based, undermining tenure security, while redistribution has transferred less than 14% of agricultural land, far below the 30% target. Beneficiaries under the Proactive Land Acquisition Strategy (PLAS) often hold insecure lease agreements, and most households in former homelands lack title deeds, perpetuating vulnerability. The weak institutional capacity, poor coordination, and inadequate post-settlement support further constrain progress. The review concludes that the most fundamental policy priority is establishing a unified national framework that guarantees secure land tenure through the issuance of title deeds, complemented by integrated post-settlement support and transparent beneficiary selection. Strengthening tenure security is essential for enabling investment, improving livelihoods, and achieving equitable and sustainable land reform. Full article

Digital transformation has emerged as a key driver of modernization in the private and public sectors. In recent years, governments worldwide have turned to digital technologies to improve efficiency, reduce costs, and enhance citizen engagement. Saudi Arabia, through Vision 2030, launched one of the most ambitious national digital transformation programs, aiming to reposition the country as a leading digital government. The Saudi government initiated a wide range of digital initiatives across ministries, agencies, and public institutions—marking a critical period of structural, technological, and cultural change in the public sector. Despite the scale and significance of this transformation, academic research on Saudi Arabia’s DT efforts remains limited. Most available insights are derived from media reports, conference presentations, or informal commentary, with minimal empirical evaluation. This study addresses that gap by conducting a comprehensive qualitative case study to assess the progress, challenges, and outcomes of digital government transformation in Saudi Arabia during the 2017–2020 period. This research examines digital transformation in the public sector of an emerging economy. It highlights three essentials: institutional coordination, systems to track progress, and long-term investment in digital skills and infrastructure. The researcher interviewed staff from the digital unit and ministry teams, conducted fieldwork, and analyzed official documents and websites. The findings indicate substantial progress in digitizing public services and enhancing user access. However, persistent challenges remain, particularly in data integration, policy alignment, and inter-agency collaboration. Full article

Tuberculosis (TB) remains a public health threat in low- and middle-income countries (LMICs) of the World Health Organization (WHO) Eastern Mediterranean Region (EMR), driven by a combination of social determinants including undernutrition, fragile health systems, conflict-related disruptions, human mobility and displacement, sub-optimal programmatic implementation, and insufficient domestic investment. These programmatic and governance constraints operate within a broader geopolitical context marked by conflict, sanctions, protracted crises, and large-scale displacement, which further limit countries’ ability to deliver uninterrupted TB services. In 2023, the region’s TB incidence was estimated at 116 per 100,000 population, with Pakistan alone accounting for about 73% of the regional burden. Despite a multitude of efforts, progress in reducing the TB burden in the EMR remains slow, with high case detection and treatment coverage gaps, low uptake of TB preventive treatment (TPT), underutilization of WHO-recommended rapid diagnostics, and only 25% of drug-resistant TB (DR-TB) cases initiated on treatment. Vulnerable populations, including internally displaced persons, migrants, refugees, prisoners, and returnees, continue to face major access barriers, and cross-border TB collaboration remains limited. This commentary reasons that the slow pace of TB burden reduction in the region is not only a biomedical or resource issue but also a reflection of structural and governance shortcomings. It proposes a ten-point strategic vision focused on building a sustainable ecosystem, enhancing primary healthcare systems, adopting people-centered and rights-based approaches, leveraging artificial intelligence, and gradually reducing dependency on external donors where feasible. However, in highly fragile settings such as Yemen or Somalia, domestic financing remains limited, and sustained external support will continue to be indispensable. The commentary calls for stronger national leadership, inclusive stakeholder engagement, and increased domestic financing to deliver integrated and resilient TB services. Ending TB in the EMR is within reach, but it requires boldly committed, coordinated, and country-led action. Full article

Deposit Refund Systems (DRS) are widely adopted in many European countries as effective mechanisms for increasing recycling rates and promoting circular-economy practices. Greece is currently preparing for the introduction of a national DRS for beverage containers, a transition expected to reshape existing waste-management structures. This study investigates the systemic challenges that may hinder the successful implementation of the upcoming Greek DRS. Focusing exclusively on polyethylene terephthalate (PET), aluminum, and glass beverage containers, this study adopts a multi-stakeholder qualitative approach involving 28 semi-structured interviews with beverage producers, retailers, recyclers, logistics actors, consumer representatives, and regulatory authorities. Thematic analysis reveals four interdependent barriers: restricted consumer accessibility due to uneven distribution of return infrastructure; fragmented governance and unclear institutional responsibilities; weak coordination and operational misalignment among supply-chain actors; and low consumer participation shaped by behavioral and cultural factors. These findings underscore that Greece’s DRS readiness is constrained not by technological limitations but by systemic gaps in governance, infrastructure planning, and stakeholder collaboration. This study contributes to the DRS literature by providing one of the first pre-implementation, multi-actor assessments in a Southern European context and offers policy-relevant insights to support an effective, equitable, and transparent rollout of the national DRS.

Evaluating the relationship between dynamic carbon emission intensity (CEI) and high-quality economic development (HQED) provides crucial insights for advancing national strategies focused on ecological preservation and sustainable high-quality development. This study employed an integrated analytical framework that combines the entropy-weight TOPSIS model, the coupling coordination degree (CCD) model, the spatial autocorrelation, and a two-way fixed effects model to examine the spatiotemporal patterns and influencing factors of carbon emissions in the Yangtze River Basin from 2010 to 2022. The results indicated that: (1) Temporal analysis revealed a consistent annual decline in CEI levels, coupled with steady improvements in HQED. The coordination between these two systems was reflected in the estimated CCD, and it showed an upward trend, with the lower reaches experiencing the most rapid progress in coordination. (2) Spatial analysis revealed a polycentric development pattern, with Shanghai serving as the central core, and other metropolises such as Nanjing and Hangzhou acting as secondary cores. The high–high agglomeration area has been progressively expanding each year. (3) Analysis of influencing factors revealed that their impacts diminished in the following order: human capital, economic development, urbanization, green innovation, government support, industrial structure, and openness. Each of these influencing factors demonstrated distinct spatiotemporal heterogeneity, varying in their impact across different regions and time periods. The study finally provided recommendations, emphasizing the need for coordinated development strategies in the YREB, taking regional dynamics into account, and promoting green economic transformations while ensuring ecological and environmental sustainability.

Tourism is a key driver of regional economies, but concerns are often raised about the effectiveness with which public resources are managed and translated into tangible outcomes. Despite its importance, research on the efficiency of public spending on tourism remains scarce and mostly confined to national scales. Therefore, this study examines how Apulian municipalities (Italy) convert public tourism expenditure into measurable tourism results, providing new evidence on the efficiency of local governance in this sector. The analysis applies a two-step econometric framework combining Stochastic Frontier Analysis (SFA) and Multiple Linear Regression to data from 247 municipalities over the period from 2020 to 2023. The results reveal generally low average efficiency levels, with only a few coastal destinations achieving high performance. The regression analysis identified key structural and territorial drivers of efficiency, including accommodation capacity, cultural production, coastal and environmental quality, and the presence of agritourism and campsites. The findings suggest that efficiency depends more on the ability of local administrations to coordinate tourism, cultural, and environmental policies than on the amount of spending. Overall, the study provides empirical evidence that an efficient allocation of tourism funds is crucial for achieving long-term sustainability goals, offering practical insights for designing more effective tourism policies.

Drawing on panel data from 279 prefecture-level cities in China from 2011 to 2022, this study employs the National Pilot Policy of Information Benefiting the People (NPIB) as a quasi-natural experiment to examine how government-led digital governance shapes the digital divide among cities. Using a difference-in-differences (DID) design combined with mediation and spatial analyses, the results demonstrate that the NPIB policy significantly narrowed inter-city digital disparities, with findings robust across alternative model specifications and placebo tests. Mechanism analysis shows that digital governance promotes inclusion primarily through three pathways: strengthening strategic policy orientation, enhancing technological innovation capacity, and stimulating digital market vitality. Heterogeneity analysis indicates that policy effects vary by regional development, urbanization level, and fiscal autonomy, being most pronounced in eastern cities and those with moderate urbanization and fiscal self-sufficiency. Spatial analysis reveals that while digital governance improves local inclusion, it can generate negative spillovers among neighboring cities with similar economic structures, partially offsetting aggregate gains. Overall, the findings highlight the importance of regionally differentiated strategies, cross-regional coordination, and sustained investment in digital infrastructure to promote balanced, inclusive, and sustainable digital transformation—providing practical insights for developing countries aiming to bridge structural divides and advance digital sustainability.

Access to safe water and sanitation remains a pressing challenge in Sub-Saharan Africa. Rapid urbanisation, fragile governance, and increasing climate hazards continue to undermine the sustainability of WASH (Water, Sanitation and Hygiene) services. This study examines whether Mozambique’s normative and institutional framework effectively supports sustainable urban WASH service delivery in Beira, the country’s second-largest city. Combining a critical policy review with six semi-structured interviews involving institutional actors and community leaders, the research employs a qualitative, phenomenological design to explore the interaction between national frameworks and local practices. Findings reveal five interrelated dimensions shaping sustainability: governance coordination, infrastructure robustness and maintenance, community participation, climate resilience, and financial viability. Although post-disaster investments and recent policy reforms have led to improvements, significant challenges persist. These include overlapping institutional mandates, underdeveloped preventive maintenance systems, limited recognition and support for community-led initiatives, fragmented climate adaptation efforts, and strong dependence on external funding. The study also reveals how historical legacies, particularly colonial-era governance structures, continue to shape water and sanitation delivery. By integrating policy analysis with local perspectives, the paper contributes to debates on WASH sustainability in African cities, particularly in climate-vulnerable secondary urban centres. It highlights the need for systemic reforms that clarify institutional roles, institutionalise maintenance practices, formalise community engagement, embed nature-based adaptation strategies, and strengthen financial transparency. These changes are essential if Beira, and similar cities across sub-Saharan Africa, are to achieve Sustainable Development Goal 6 under mounting climate pressure. Full article

Digitalization and greening are two fundamental forces shaping the current technological revolution and industrial transformation, serving as key pathways for nations to achieve sustainable development goals. Drawing on panel data from 30 Chinese provinces from 2012 to 2022, this study constructs indicators of digitalization and greening from the perspectives of data empowerment and technological efficiency improvement and examines how their synergistic development influences industrial structure optimization. The findings reveal the following: (1) although the overall synergy between digitalization and greening has steadily increased, regional disparities persist, displaying an “East strong–West weak” pattern, with inter-regional differences being the primary source of overall imbalance; (2) through the mediating role of environmental regulation, the coordinated advancement of digitalization and greening exerts a significant positive effect on industrial structure optimization; (3) heterogeneity analysis indicates a gradient empowerment effect, showing that the impact of digitalization–greening synergy on industrial structure optimization follows a “West > Central > East” pattern. These results provide both theoretical and empirical evidence for understanding how digitalization and greening jointly drive sustainable development. The study offers practical insights for guiding traditional industries to integrate into circular economy systems through “digitalization + greening” transformation and recommends that governments adopt differentiated strategies tailored to local conditions, enhance digital infrastructure, promote green initiatives, deepen reforms, and innovate regulatory frameworks to foster the synergistic advancement of digitalization and greening.

This study develops a composite index to identify and prioritize the most suitable geographical locations for rural Community Renewable Energy (CRE) projects. CRE is central to the sustainable energy transition, but its strategic deployment in rural areas is challenging due to uneven development, the necessity of coordinating diverse resources, and the need for governments to guarantee the prudent use of scarce funds. Framed under the Resource Mobilization Theory, the proposed index helps mitigate these uncertainties by providing a structure for site evaluation. Although the empirical application is performed in a specific Portuguese region, the methodological approach is explicitly designed to be transferable to other national and regional contexts. The index provides significant practical implications for CRE promoters, investors, and spatial planners, offering a transparent, clear-cut tool to define targets and optimize resource allocation. Furthermore, this study contributes to rural development literature by merging entrepreneurship and renewable energy fields, demonstrating how local CRE can effectively leverage available resources to deliver both private and community benefits.

The study investigates how agriculture can serve as a driver of sustainable tourism and local development within the Vesuvius National Park under the European Charter for Sustainable Tourism (ECST) framework. Based on 14 semi-structured interviews with farmers, tourism operators, cultural institutions, and producer consortia, the findings reveal that agriculture plays a central role not only as a productive sector but also as a custodian of biodiversity, identity, and territorial resilience. Stakeholders emphasised the economic and symbolic value of traditional crops, highlighting how farm-based experiences, product certifications, and civil-society networks strengthen community cohesion and diversify visitor flows. Nevertheless, tourism remains predominantly concentrated in the vicinity of the volcano’s crater, thereby excluding the park’s other trails, limiting the positive impacts on rural and peripheral areas. Practical implications point to the need for improved mobility infrastructure, cross-sector coordination, and targeted incentives to link agrotourism circuits with regional branding and EU sustainability policies. Overall, the study shows that integrating agriculture into tourism governance can foster more inclusive, resilient, and territorially embedded forms of rural development in protected areas.

The coordinated development of Production-Living-Ecological (PLE) spaces has emerged as a core challenge for regional sustainability amid rapid urbanization processes. This study examines the Guanzhong Plain Urban Agglomeration (2001–2021) using an integrated Markov-PLUS model coupled with Random Forest algorithms and 17 driving factors to construct 4 policy scenarios for future projections. The results reveal dramatic spatial restructuring: living space expanded 73.89% while production and ecological spaces contracted 7.47% and 8.94%. Evolution occurred through four distinct phases—rapid expansion, structural adjustment, quality improvement, and green transformation—each corresponding to national policy transitions with regional lags. Driving mechanism analysis identified environmental factors contributing 45–55% of variance, population density driving 24.2% of living space expansion, and elevation thresholds constraining urban growth above 1000 m. Multi-scenario simulations revealed fundamental trade-offs: urban development scenarios achieved 55.34% built-up expansion but sacrificed 15.4% ecological space, while ecological protection scenarios maintained 92% food production capacity with optimal connectivity (0.63) and maximum carbon storage (1287 Mt C). Model validation achieved exceptional accuracy (Kappa = 0.91, FoM = 0.24). This research emphasizes three strategic imperatives: (1) differentiated spatial governance (urban priority in cores, farmland protection in plains, ecological restoration in mountains); (2) temporal coordination mechanisms accounting for 3–5-year policy transmission lags; (3) adaptive management approaches addressing nonlinear evolution characteristics. This framework provides scientific foundations for balancing economic development, food security, and ecological protection in rapidly urbanizing regions. Full article

Effective carbon emission control at the provincial level is essential for advancing the high-quality development of the national economy under the “dual carbon” targets. Although Hubei Province is endowed with abundant natural resources and significant potential for sustainable growth, it still faces considerable challenges in industrial and energy restructuring. Therefore, improving carbon emission efficiency (CEE) is imperative. This study thoroughly analyzes the spatial and temporal characteristics of CEE in Hubei Province. Furthermore, the spatial Durbin model (SDM) and geographically and temporally weighted regression (GTWR) were applied to analyze the determinants of changes in CEE. The results indicate that significant disparities in CEE exist across Hubei Province, with the eastern region exhibiting the highest efficiency and the central region the lowest. The year 2016 represented a turning point, as Moran’s I increased from −0.0006 in 2016 to 0.5134 in 2017, indicating a shift in the spatial pattern of CEE from a weak and insignificant spatial autocorrelation to a strong positive spatial autocorrelation. In addition, the CEE in Hubei Province demonstrated a “siphon effect” and exhibited pronounced polarization. Based on these findings, region-specific policies are proposed. The eastern region should optimize its industrial structure and strengthen urban governance. The western region should leverage its clean energy advantage and enhance carbon sink capacity. The central region should advance low-carbon industrial transformation and coordinated governance to prevent core cities from transferring resources and pollution to surrounding areas. Full article
