This study reviews the existing research on international environmental agreements (IEAs) from the perspective of environmental economics, with a particular focus on recent research trends and classic theoretical models. Since the last century, the body of research surrounding IEAs has steadily grown, with numerous scholars exploring various approaches to the formation of stable and effective agreements. While some studies have attempted to organize this literature, classifications based on thematic features remain relatively rare. Therefore, this work identifies common threads across the literature addressing transboundary pollution issues and categorized them thematically, highlighting both recent focal points and classic models. Specifically, the existing research on addressing transboundary pollution is divided into four categories: studies focusing on the national attributes, the mechanisms of cooperation within IEAs, the structures of IEA cooperation, and the alternative approaches beyond IEAs. This review aims to provide policymakers with a clear summary of recent research on international environmental cooperation and to offer advanced guidance for achieving global sustainable development.

Energy is at the center of economic growth and environmental sustainability. Increasing energy efficiency and turning to environmentally friendly technologies are indispensable elements not only in reducing carbon emissions but also in supporting the transition to a green future. This study aims to deeply examine the simultaneous dynamic interactions between energy, environmental technologies, and economic growth by focusing on the environment and analyzing the transformative effects of these factors on environmental sustainability from a broad perspective. The models were estimated via simultaneous equation systems with two-stage and three-stage least squares methods with monthly data for Organization for Economic Cooperation and Development (OECD) countries between 1990 and 2021. As a result of the analyses, the estimation results of the two methods generally support each other. Notably, economic growth causes carbon emissions, and when tax revenues on energy are added to the model, the negative effect of economic growth on carbon emissions turns positive. Another significant result shows that energy efficiency does not reduce carbon emissions. Even an increase in energy efficiency causes an increase in carbon emissions, and the rebound effect is valid. Population and energy density do not have a negative impact on carbon emissions.

The European Charter for Wine Tourism (2005) promotes the sustainable development of tourism activities associated with viticulture. The document identifies the active role that wine-growing territories must play in the conservation, management, and valorization of their resources. This study aims to understand the degree of linkage that this Charter establishes with initiatives for the heritage of wine culture, specifically focusing on wine museums in Spain. It examines how these museums contribute to defining a tourism development program, constructing a common strategic vision, and encouraging cooperation between the social and economic agents involved in the territory. As case studies, the Vivanco Museum of Wine Culture (La Rioja), considered by World Tourism Organization (UNWTO) as the best in the world, and the Valdepeñas Wine Museum (Castilla-La Mancha), an example of rehabilitation and musealization in the region with the highest concentration of vineyards in the world, have been chosen. The results show that both museums exemplify management, development, and cooperation in their respective territories, aligning with the theoretical assumptions established in the Charter.

The H5N1 avian influenza virus continues to evolve into genetically diverse and highly pathogenic clades with increased potential for cross-species transmission. Recent scientific advances have included the development of next-generation vaccine platforms, promising antiviral compounds, and more sensitive diagnostic tools, alongside strengthened surveillance systems in both animals and humans. However, persistent structural challenges hinder global readiness. Vaccine production is heavily concentrated in high-income countries, limiting equitable access during potential pandemics. Economic and logistical barriers complicate the implementation of control strategies such as vaccination, culling, and compensation schemes. Gaps in international coordination, public communication, and standardization of protocols further exacerbate vulnerabilities. Although sustained human-to-human transmission has not been documented, the severity of confirmed infections and the rapid global spread among wildlife and domestic animals underscore the urgent need for robust preparedness. International organizations have called for comprehensive pandemic response plans, enhanced multisectoral collaboration, and investment in targeted research. Priorities include expanding surveillance to asymptomatic animal hosts, evaluating viral shedding and transmission routes, and developing strain-specific and universal vaccines. Strengthening global cooperation and public health infrastructure will be critical to mitigate the growing threat of H5N1 and reduce the risk of a future influenza pandemic. Full article

Background/Objective: South Korea continues to have the highest suicide rate among the Organization for Economic Co-operation and Development (OECD) countries, with a growing number of emergency department (ED) admissions related to self-harm and suicide attempts. However, trauma-focused analyses that integrate psychiatric profiles and suicide mechanisms remain limited, hindering effective clinical care and preventive strategies. Methods: This retrospective study analyzed trauma patients who presented to the ED of Wonju Severance Christian Hospital following suicide attempts between October 2015 and December 2023. Of 305 self-harm cases, 208 survivors who underwent psychiatric evaluation were included. The variables analyzed included the mechanism, site, and severity of injury (ISS and AIS); psychiatric diagnosis and prior psychiatric history; repeated suicide attempts; alcohol use; physical pain; interpersonal conflict; and economic vulnerability. Chi-square, Fisher’s exact, and Kruskal–Wallis’ tests were used for statistical comparisons. Results: Stabbing/cutting (56.7%) and falling (35.6%) were the most common attempts. Mood disorders were the predominant psychiatric diagnosis (63.9%), followed by adjustment disorders (26.0%), alcohol use (25.5%), and psychotic disorders (22.1%). Among the fall-related cases, patients were typically younger and predominantly women. The median ISS was highest in fall-related cases (17) compared with stabbing/cutting (4), with 25.96% of patients with an ISS ≥16, indicating severe trauma. A psychiatric history was associated with a higher incidence of falls (44.3%), and previous suicide attempts correlated with the use of high-lethality attempts. Severe physical pain was linked to stabbing/cutting in 10 of 11 cases. Interpersonal conflict was more frequently associated with stabbing/cutting (59.6%) than with falls (31.9%). No significant association was found between alcohol use and the method of suicide attempt. Conclusions: The suicide mechanisms in patients with trauma are closely associated with psychiatric and psychosocial factors. Stabbing/cutting is often impulsive and driven by interpersonal conflict or alcohol use, while falling is more frequent in patients with psychiatric histories of repeated attempts. These findings emphasize the importance of mechanism-informed psychiatric evaluations and trauma protocols. Regionally adapted, interdisciplinary approaches and early psychiatric intervention are crucial for effective post-attempt management and suicide prevention. Full article

Strengthening producer groups, the rural community, and agri-food chains are important actions to help solve the problem of food poverty, improve the living conditions of producers and promote sustainable development in rural México. It is necessary to seek new ways to improve decision-making by producer groups and establish some principles to strengthen the different links in agri-food chains. The objective of this study was to analyze the integration of the Principles for Responsible Investment in Agriculture (PRIA) in the corn agri-food chain in order to assess its strengthening. A study was carried out in three cases based on the application of the “Working With People” (WWP) model as well as interviews with key actors. It was found that cooperating groups with a higher degree of application of the WWP model and PRIAs have a higher degree of stability and sustainable development and strengthen the integration and cooperation of local action groups. These groups have the technical component better organize the agri-food processes and better incorporate the PRIAs and improve their economic, social, and environmental development compared to other groups that do it in a traditional way.

Background: Emerging and re-emerging infectious diseases (EIDs and Re-EIDs) cause significant economic crises and public health problems worldwide. Epidemics appear to be more frequent, complex, and harder to prevent. Early warning systems can significantly reduce outbreak response times, contributing to better patient outcomes. Improving early warning systems and methods might be one of the most effective responses. This study employs a bibliometric analysis to dissect the global research hotspots and evolutionary trends in the field of infectious disease early warning, with the aim of providing guidance for optimizing public health emergency management strategies. Methods: Publications related to the role of early warning systems in detecting and responding to infectious disease outbreaks from 1999 to 2024 were retrieved from the Web of Science Core Collection (WoSCC) database. CiteSpace software was used to analyze the datasets and generate knowledge visualization maps. Results: A total of 798 relevant publications are included. The number of annual publications has sharply increased since 2000. The USA produced the highest number of publications and established the most extensive cooperation relationships. The Chinese Center for Disease Control & Prevention was the most productive institution. Drake, John M was the most prolific author, while the World Health Organization and AHMED W were the most cited authors. The top two cited references mainly focused on wastewater surveillance of SARS-CoV-2. The most common keywords were “infectious disease”, “outbreak”, “transmission”, “virus”, and “climate change”. The basic keyword “climate” ranked the first and long duration with the strongest citation burst. “SARS-CoV-2”, “One Health”, “early warning system”, “artificial intelligence (AI)”, and “wastewater-based epidemiology (WBE)” were emerging research foci. Conclusions: Over the past two decades, research on early warning of infectious diseases has focused on climate change, influenza, SARS, virus, machine learning, warning signals and systems, artificial intelligence, and so on. Current research hotspots include wastewater-based epidemiology, sewage, One Health, and artificial intelligence, as well as the early warning and monitoring of COVID-19. Research foci in this area have evolved from focusing on climate–disease interactions to pathogen monitoring systems, and ultimately to the “One Health” integrated framework. Our research findings underscore the imperative for public health policymakers to prioritize investments in real-time surveillance infrastructure, particularly wastewater-based epidemiology and AI-driven predictive models, and strengthen interdisciplinary collaboration frameworks under the One Health paradigm. Developing an integrated human–animal–environment monitoring system will serve as a critical development direction for early warning systems for epidemics. Full article

The rapid urbanization of the world has brought significant environmental, social, and economic challenges to human society. To build a sustainable county, there are many limiting factors, such as the environment, financial resources, and population. Based on this, the purpose of this study is to investigate how countries can empower their development through a sustainable design path for parks with the participation of all. The core of public participation in co-construction lies in the interactive relationship between the government, society, citizens, and many other groups. That is, “co-construction, co-governance, and sharing” is the basic content of the new pattern of social governance from the perspective of the park city; at its core is joint participation, division of labor, and cooperation. Using qualitative research methods, Kaiyuan, a county in Yunnan Province, was selected as a case study, focusing on the Phoenix Ecological Park and Happiness Lawn; citizens and managers were interviewed to explore paths for sustainable design in the counties. The contribution of this study is a research model of sustainable design for county parks with the participation of all the people. The study found that public participation should consider multiple co-constructions and formulate a sound sustainable design path from three dimensions: counties, managers, and citizens. Combined with the local characteristics of counties, the government has called on enterprises, organizations, and citizens to participate together in improving the quality of life and happiness of county residents. The results can be further verified in other counties. Full article

The Organization of Economic Cooperation and Development Working Party on Pesticides (OECD WPP) Drone/UAV Subgroup published a “state of the knowledge” report on pesticide application using unmanned aerial vehicles (UAV) in 2021. One of the recommendations made in this report was to “develop and publish a user-friendly summary of best practices (including the essential nature of calibration), pitfalls and a trouble shooting guide (both for generating trials data and applying pesticides in practice)”. In response to recommendations in that report, the pesticide registrant industry in the United States formed the global Unmanned Aerial Pesticide Application System Task Force (UAPASTF). This report outlines the overview of the “Best Management Practices” (BMP) guidance that was developed by the UAPASTF. UAV-based spraying of crop protection products is relatively new for most of the regions globally. Therefore, this guidance document is intended to serve as an excellent resource for growers, researchers (both academics and industry) and other relevant stakeholders to carry out UAV-based spray application in an efficient and safe manner.

Background/Objectives: This systematic review evaluates unconventional mammalian models from wild, agricultural, and urban/domestic ecosystems for genotoxicity assessment under the One Health framework. Non-human primates (NHPs), cattle, and domestic dogs are analyzed as sentinel species due to their distinct environmental niches, unique human interactions, and species-specific traits. In conjunction with this, evidence is presented about the in vitro use of cells of these mammals for the genotoxicological evaluation of different chemical substances, such as veterinary drugs, environmental pollutants, and pesticides. The synthesis focuses on standardized genetic toxicology assays (e.g., chromosomal aberrations, micronucleus, comet assay) aligned with Organization for Economic Cooperation and Development (OECD) guidelines. Methods: A structured search of international literature identified studies employing OECD-compliant genotoxicity assays in NHPs, cattle, dogs, and others not listed in OECD. Data was categorized by species, assay type, chemical class evaluated, environmental context (wild, agricultural, urban), and merits of the papers. Results: NHPs, despite their phylogenetic proximity to humans, show limited genotoxicity data in contrast to biomedical research, which has been constrained by ethical concerns and fieldwork logistics. Cattle emerge as robust models in agricultural settings due to the abundance of studies on the genotoxic capacity of pesticides, veterinary drug, and environmental biomonitoring, with direct implications for food safety. Domestic dogs are recognized as powerful sentinels for human health due to shared exposomes, physiological similarities (e.g., shorter cancer latency), and reduced lifestyle confounders; however, genotoxicity studies in dogs remain sparse compared to chemical exposure monitoring or cancer research. Conclusions: This review advocates for expanded, integrated use of these models to address genotoxic threats across ecosystems, which would benefit both animal and human health. In the application of biomonitoring studies with sentinel animals, a critical gap persists: the frequent lack of integration between xenobiotic quantification in environmental and biological samples, along with genotoxicity biomarkers evaluation in sentinel populations, which hinders comprehensive environmental risk assessment.

Amid global economic transformation, a persistent productivity gap exists between developed and developing nations in agriculture sector, shaped by technological advancements and shifting resource allocation patterns. Agricultural socialized services (ASS), defined as organized systems providing technical support, mechanization assistance, information services, market linkages, and resource optimization to farmers, have emerged as critical mechanisms for agricultural development. In developing economies, these services catalyze gains in agricultural labor productivity through the integration of advanced technologies and the mechanization of farming practices. Using panel data from 30 Chinese provinces during 2011 to 2022, this study investigates the relationship between ASS and ALP, focusing on regional heterogeneity, threshold effects, and spatial spillovers. The combination of spatial econometric methods and threshold analysis was selected for its unique capacity to capture both the geographic interdependencies and nonlinear relationships that characterize agricultural development processes. These thresholds at 5.254 and 8.478 represent critical points where the impact of ASS on ALP significantly changes in magnitude, revealing a nonlinear relationship that evolves across different stages of agricultural development. The study highlights notable regional disparities in the impact of ASS. Specifically, ASS is more effective on ALP in eastern, central and key food-producing regions, while its impact is relatively weak in western and non-food-producing regions. Spatial spillover analysis indicates that advancements in ASS create positive externalities, extending beyond their immediate implementation zones and facilitating inter-provincial agricultural cooperation and development. These findings provide crucial guidance for policymakers and agricultural service providers to optimize resource allocation and service delivery strategies. By identifying critical development thresholds and regional variations, this research offers evidence-based support for government officials designing targeted agricultural policies and enterprises developing region-specific service models to foster sustainable agricultural growth across diverse regional landscapes.

Background: The COVID-19 pandemic has sparked the need for appropriate government responses in health-disaster situations worldwide. This study analyzes the impact of governments’ non-pharmaceutical measures on the number of deaths from COVID-19. In particular, it further analyzes how trust in government moderates government measures. Through this analysis, this study aims to explore the government’s appropriate role in overcoming future health disasters by understanding the effectiveness of government measures in response to the COVID-19 pandemic. Methods: This study collected and analyzed national data provided by various international organizations for countries of the Organization for Economic Co-operation and Development (OECD). To estimate the relationship between various policy measures and COVID-19 related deaths, it employed panel data analysis using random effects, since only three years of data, ranging from 2020 to 2022, were utilized. Results: The main findings of this study are as follows. First, suppression measures which include measures that place relatively stronger restrictions on people’s behavior were directly related to decreases in the number of total deaths. However, mitigation measures which consisted of weak-intensity measures were directly related to increases in the number of deaths. Second, higher levels of trust in government were directly related to decreased numbers of deaths. Finally, the moderating effect of government trust on suppression measures was not tested, but the moderating effect on mitigation measures was confirmed. Conclusions: This study presents the following implications. First, governments’ non-pharmaceutical measures in times of pandemic need to consider various environmental factors of the country. Second, trust in government can be an important environmental condition in overcoming health-disaster situations. In particular, trust in government weakens the side effects that can be caused by government measures. Third, suppression methods that directly affect people’s movement and daily life had a positive association with decreases in the number of total deaths, and the correlations of these measures in overcoming the health-disaster situation were confirmed.

This study examines the impact of financial development, renewable energy, energy intensity, and stringent environmental policies on green growth in twenty-three Organization for Economic Cooperation and Development countries from 2000 to 2023. Additionally, it examines how stringent environmental policies moderate the link between financial development and green growth. Economic complexity, trade openness, and green technology variables are also included in the model as control variables. The index is constructed using economic growth, education, health, CO₂ emissions, net forest, and mineral components for green growth, the main variable explained in the research. The Fully Modified Ordinary Least Squares method is applied to estimate elasticity coefficients in the study. The findings show that financial development and energy intensity have a negative impact on green growth, whereas strict environmental policies and renewable energy support green growth. Moreover, the interaction between financial development and stringent environmental policies promotes green growth. At the same time, the control variables of trade openness and economic complexity have a negative impact on green growth, while green technology makes a positive contribution. Furthermore, financial development and energy intensity have the most significant quantitative impact on green growth, while trade openness and stringent environmental policies have the least impact. In line with these findings, environmentally friendly financial instruments and green investments should be supported instead of directing financial resources only to industry-intensive sectors in Organization for Economic Cooperation and Development countries. In this context, implementing energy efficiency policies and increasing incentives for renewable energy are of great importance. Full article

With the rapid development of China’s rural economy, rural collective economic organizations have played a significant role in increasing farmers’ income and promoting rural revitalization. This study aims to explore the impact of farmers’ participation in skills training organized by rural collective economic organizations on their livelihood capital and the underlying mechanisms. Using tracking survey data from rural households in Chongzhou City, Sichuan Province, in 2023, the paper employs empirical analysis methods, including OLS and mediation effect analysis. The results show that participation in skills training organized by rural collective economic organizations enhances farmers’ livelihood capital. The effectiveness of public service delivery by village committees, the network role of farmers’ cooperatives, and the linkage effect of leading agricultural enterprises in driving rural development act as mediating factors. Additionally, the impact of skills training on farmers’ livelihood capital varies according to household characteristics and the attributes of the rural collective economic organizations involved. Therefore, this paper proposes the following policy recommendations: (1) Further strengthen the public service and resource allocation functions of the village committees. (2) Support and optimize the operating entities such as farmer cooperatives and leading agricultural industrialization enterprises. (3) Address the training needs of different groups and enhance the focus and support of grassroots governments for skills training in collective economic organizations. Full article

The objective of this research is to examine the role of intellectual property (IP) in fostering business development, particularly focusing on patent management in Ecuador and its alignment with international standards. The study employs a comparative analysis of Ecuadorian legislation against the framework established by the World Intellectual Property Organization (WIPO) to identify challenges and opportunities within the national IP system. Key methods include reviewing existing legal texts, interviewing stakeholders, and analyzing patent registration processes. The findings indicate that while Ecuador has made significant strides in harmonizing its IP laws with international treaties, such as the Patent Cooperation Treaty (PCT) and the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), considerable barriers remain, particularly related to bureaucratic inefficiencies and a lack of technical resources in key institutions like the National Service of Intellectual Rights (SENADI). The conclusions highlight the need for enhanced efficiency and implementation of IP regulations to stimulate sustained innovation growth, attract national and foreign investments, and, ultimately, strengthen Ecuador’s competitiveness in a global economy. This research contributes to the understanding of how effective IP management can serve as a vital tool for economic development and innovation. Full article
