A Novel Decomposition Framework for Agricultural Growth Accounting: A Global Supply Chain Perspective

ABSTRACTIn this article, we delve into the traditionally opaque total factor productivity (TFP) “black box” by dissecting it into its constituent elements—technology and efficiency—based on input–output variables from a global supply chain vantage point. Utilizing growth accounting methods, the article seeks to discern the variety of routes through which technology (frontier movement) and efficiency (catch‐up effects) propagate their effects on TFP. Our primary objective is to identify the most potent mechanism for fostering productivity enhancement, a task that previously eluded systematic examination. The methodology involves creating an empirical approximation of the agricultural production frontier from a selection of national data. Bounded‐adjusted linear programming techniques are subsequently employed to disentangle the observed TFP growth within the agricultural sector of each country into its technology and efficiency facets. It is important to note that this study also integrates resource and environmental footprints as additional input–output variables, quantified via the multi‐region input–output (MRIO) model. The analysis, spanning from 2000 to 2016, reveals that the most advanced nations demonstrate the most vigorous growth in agricultural productivity, with a global upward trend in agricultural productivity over the sampled years.

Investigating young consumers’ acceptance of hemp fiber textiles and apparel: an analysis of Partial Least Squares Structural Equation Modeling

Purpose Concerns over environmental degradation, alongside the global legalization of hemp cultivation, have prompted applications of hemp-derived textile products. However, research examining consumers’ acceptance of such products is lacking. It is critical to understand how young consumers adopt these products as they prioritize sustainability and lead the future purchasing power. Thus, this study aims to investigate young consumers’ perceptions, attitudes, and purchase intentions regarding hemp fiber textiles and clothing based on the Theory of Consumption Value and the Spiral of Silence Theory. Design/methodology/approach A US-based research company was hired to recruit survey participants, yielding 314 valid data. Data analysis, including Exploratory Factor Analysis and Partial Least Squares Structural Equation Modeling, was conducted using the R programming language and RStudio software. Findings Purchase intentions of hemp-based clothing and textiles among young consumers are influenced by attitude, perceived social value and future trend perception. Perceived social value also impacts attitude and future trend perception. High environmental involvement correlates with positive attitudes. Consumers’ subjective knowledge of hemp and objective knowledge regarding hemp fiber impact their perceptions of future trends in such products. Originality/value This research represents a seminal consumer study focusing on the resurgence of industrial hemp fiber textiles and clothing. This study empirically validates the significant role of social factors in young consumer acceptance of such products at both personal and societal levels. This study expands current knowledge and provides actionable insights for practitioners.

Analyzing the adoption of nutrition-sensitive carp-SIS polyculture technology: evidence from a case study in Bangladesh

IntroductionSmall indigenous species (SIS) of fish are rich in micronutrients that are essential to combat the existing malnutrition in Bangladesh. However, their availability is constantly decreasing due to gradual environmental degradation making their availability irregular and hence expensive in the market. Integrating SIS with carps in homestead ponds is being promoted as a form of nutrition-sensitive aquaculture to enhance both production and consumption of these nutrient-rich species. Various improved pond management techniques (IPMTs) are suggested to boost the nutrition-sensitive carp-SIS polyculture.ObjectivesThis study examines the trends and factors influencing the adoption of IPMTs using the sustainable livelihood framework (SLF) approach. We address the following three key questions: (i) What are the trends in production and consumption of fish, in particular SIS from homestead ponds? (ii) Have farm households adopted or disadopted IPMTs over time? (iii) What are the determinants of adoption and disadoption of IPMTs?MethodsBased on primary data of 234 households from Barishal district from 2014 and 2022, we perform significance tests to compare project and non-project households in 2014 versus 2022 and apply fixed effects Poisson regression and fixed effects negative binomial regression models to identify household decisions to adopt the IPMTs.Results and conclusionQuantitative survey results indicate a significant increase in the production and consumption of SIS over time. In 2014, the project households exhibited adoption rates of 60% or more for various IPMTs such as stocking of fast-growing species, pre-stocking liming, pond dike construction, fertilizer application, stocking of high quality fish seeds, aquatic weed control, and turbidity management. However, by 2022, some of these IPMTs were disadopted by project households and only a few techniques, including providing sunlight exposure to ponds, pre-stocking liming, and supplementary feeding, were more widely used. Additionally, many non-project households also increased their adoption rates of IPMTs significantly. The fixed effects regression model shows that adoption is positively influenced by the number of household members participating in aquaculture, size of the pond, sole ownership of the pond and the number of years household has been involved in aquaculture. Follow-up activities such as monitoring and training of the project beneficiaries and government support are recommended to support long-term adoption of the IPMTs.

Temporal Trends in Soil Health and Productivity on Reclaimed Natural Gas Pipeline Rights‐of‐Way on Cropland

ABSTRACTThe construction of underground pipelines negatively impacts soil productivity in various ecosystems. However, the temporal progression in the recovery of soil productivity following the reclamation of cropland impacted by natural gas pipeline rights‐of‐way (ROWs) construction remains unclear. This study examined temporal, post‐reclamation changes in selected soil health indicators and productivity on reclaimed underground natural gas pipeline ROWs on cropland. Soil and crop samples were collected from ROWs ranging in time elapsed since reclamation (TSR) from 6 to 12 years and from adjacent undisturbed locations (off‐ROW) in the same field. The soil samples were analyzed for soil health indicators (permanganate‐oxidizable carbon (POXC), soil respiration, and autoclaved citrate‐extractable (ACE) protein) and selected chemical properties. Crop samples were assessed for grain and total biomass yields as well as grain protein content. Compared to the off‐ROW, soil organic C on the ROWs was 29% (6‐year ROW) and 33% (9‐year ROW) lower than on the off‐ROWs. Soil respiration recovered within 6 years of ROW reclamation, whereas it took 12 years for POXC and ACE protein to recover to off‐ROW levels. Grain and biomass yields 12 years post‐reclamation were still 42% and 36%, respectively, lower on the ROWs than on the off‐ROWs. However, measured soil attributes recovered faster than crop variables, indicating that pipeline construction on cropland has longer‐term impacts on crop yields than on soil attributes. These results indicate that, although underground pipeline construction has detrimental impacts on soil and crop attributes, these attributes would slowly recover to pre‐construction levels with increasing TSR.

Combined effects of urbanization and climate variability on water and carbon balances in a rice paddy-dominated basin in southern China

Abstract Urbanization is known to elevate storm runoff, but how it influences carbon cycle and ecosystem productivity through altering the evapotranspiration (ET) process is less clear. We examined the combined effects of urbanization including change in impervious surface area (ISA) and climate variability on the water and carbon balances of the Qinhuai River Basin (QRB) over 2001–2018. QRB represents a typical rice paddy-dominated region that experienced rapid urbanization in southern China. We improved a monthly scale water supply stress index ecosystem service model by integrating local eddy flux measurements and high-resolution remote sensing data. We found a significant downward trend in both ET (−4.6 mm yr−1, p < 0.05) and gross primary productivity (GPP) (−10.4 gC m−2 yr−1, p < 0.05) but a significant upward trend in water yield (Q) (+28.6 mm yr−1, p < 0.05). These ecosystem function changes coincided with a 96% increase in urban areas, 1.9-fold increase in ISA, and a 37% reduction in rice paddy fields. The mean annual watershed GPP decreased from 1048 gC m−2 to 998 gC m−2 while the annual Q increased from 284 mm to 669 mm from 2001 to 2018. Scenario modeling experiments suggested that the negative impacts of loss of rice paddy fields and increase in ISA on ET and GPP overwhelmed the positive impacts of climate warming. The reduction in GPP and increase in Q were largely attributed to the increases in ISA, not necessarily due to changes in land use types (e.g. urban area). The expansion of urban area, increase in ISA and reduction in leaf area index, and increase in precipitation explained the increase in Q. Our research offers insight about the interactions of carbon and water cycles through the critical ET processes under a changing climate and land surface characteristics at a watershed level. Our modeling tool and analysis provides land managers and policy makers information for designing effective ‘Urban Nature-based Solutions’ to mitigate the negative environmental effects of urbanization on carbon and water resources.

Weakening of global terrestrial carbon sequestration capacity under increasing intensity of warm extremes.

The net ecosystem exchange (NEE), determining terrestrial carbon sequestration capacity, is strongly controlled by climate change and has exhibited substantial year-to-year fluctuations. How the increased frequency and intensity of warm extremes affect NEE variations remains unclear. Here, we combined multiple NEE datasets from atmospheric CO2 inversions, Earth system models, eddy-covariance data-driven methods and climate datasets to show that the terrestrial carbon sequestration capacity is weakened during warm extreme occurrences over the past 40 years, primarily contributed by tropical regions (81% ± 48%). The underlying mechanism can be rooted in the overwhelmingly decreased trend of gross primary productivity compared with terrestrial ecosystem respiration. Additionally, the weakened terrestrial carbon sequestration capacity is mainly driven by the transition from temperature or soil moisture control to vapour pressure deficit control, which is associated with the increasing intensity of warm extremes. Our findings suggest that warm extremes threaten the global carbon sequestration function of terrestrial ecosystems. Therefore, more attention should be given to the evolution of the increasing intensity of warm extremes in future climate projections.

A Comparative Growth Trend Study of Tomato in Jaipur and Sirohi District of Rajasthan, India

Tomato (Licopersicon esculentum) is an important crop that contributes economically and significantly to horticulture production. T The study was conducted for the period of 12 year in Jaipur and Sirohi districts of Rajasthan to analyze the growth rate in area, production, and productivity from 2010-11 to 2021-22. (Department of Horticulture, Government of Rajasthan-2022-23). For analyzing the trend in area production and productivity of tomatoes in Jaipur and Sirohi district, and Rajasthan state the following linear, semi-log, and exponential functions were tested. The tested model were selected based on high R2 (Coefficient of determination) and the best-fit function was used for the result discussion.

The production and productivity show 9.91 and 8.15 percent growth rate. The semi-log function was also best fit the area and production of Tomato in Jaipur district with 4.58 and 15.94 percent annual growth respectively. The linear function was fitted for the productivity that shows 17.20 percent CAGR with 0.39 percent R2. The area of tomato in Sirohi district shows highest fluctuation due to this an exponential function was shows poor fits for calculate the growth rate this function shows 0.01 percent compound annual growth rate. The exponential function was best fit for the production and productivity with 0.41 and 0.31 R2 respectively. The exponential function show 11.24 percent growth rate, which was significant at 5 percent level. The productivity show 12.25 percent compound annual growth rate with 10 percent level of significance. Thus the productivity shows highest compound annual growth rate followed by Production and area in Jaipur and Sirohi district of Rajasthan, while in Rajasthan, production shows highest growth rate followed by productivity and area. According to the findings, the result suggest for the introduction of high yield varieties of tomato may increase the productivity in Rajasthan.

Indigenous Technical Knowledge and Its Potential Application to Uganda's Pig Sub‐Sector

ABSTRACTUganda's pork consumption is speculated to exceed any other livestock meat consumption by 2050. However, the current trend in pig production may not meet the demand due to pig production constraints such as recurrent disease incidences and high feeding costs. The proposed modern practices are not cost‐effective, especially for resource‐constrained pig farmers. This review, therefore, synthesises previous studies on the practicability of integrating Indigenous Technical Knowledge (ITK) in pig production to mitigate the prevailing pig production challenges in Uganda. By employing ITK, smallholder farmers have realised that indigenous pig breeds are disease‐resistant and suit the prevailing harsh tropical conditions. In addition, affordable plant‐based concoctions have been developed to cure diseases in pigs. For example, Centella asiatica has been identified as a potential purgative for diarrhoeal infections. Integrating pigs in cropping systems has also been adopted as a low‐cost alternative to effectively feed pigs for optimal performance. Fortunately, most of the ITK options for solving pig production challenges are feasible in Uganda. Thus, ITK should be embedded in the country's extension system to increase smallholder farmers' awareness about its potential of improving pig production. An ITK‐modern technology integration would probably meet the acceptance and be suitable for commercial pig producers.

Future climate impacts on crop production in Bhutan

Understanding the relationship between weather extremes and crop productivity is the backbone of risk assessments on food security. The former is paramount in countries (i.e., Bhutan) where there are a limited number of impact assessments in agriculture. The analysis performed in this work highlights the trends in agricultural production under a changing climate and the attribution of yield change to a specific climatic hazard. We improve the understanding between the two (climate and yields) by applying an FAO eco-physiological model (PyAEZ) and by relying on state-of-the-art downscaled climate projections (CORDEX-CORE). We analyze climate change impacts on ten crops (maize, foxtail millet, buckwheat, wheat, rice, common beans, cabbage, white potatoes, carrots, and citrus) at national level. The main simulation findings point to a higher yield gain and loss under rainfed conditions as opposed to irrigated conditions by the end-century (2070-2099) compared to the baseline period (2010-2039), particularly under RCP 8.5 for white potatoes (+17.7%), wheat (+15.5%), cabbage (+12.8%), buckwheat (-6.6%), and citrus (-5.8%). The irrigation potential to modulate climate change impacts is reflected in a yield gain of +43.4% on average for all crops and RCP’s when compared to rainfed conditions. On average, weather extremes explain 28% and 33% of the yield variability over time, respectively under RCP’s 2.6 and 8.5. Overall, this study supports smallholder farmers, decision-makers, and project developers to implement adaptation solutions that minimize growing weather extremes such as heat-stress and dry-spells.

Spatial and Temporal Variation of GPP and Its Response to Urban Environmental Changes in Beijing

The carbon sequestration capacity of vegetation is the key to the carbon cycle in terrestrial ecosystems. It is significant to analyze the spatiotemporal variation and influencing factors of vegetation carbon sequestration ability to improve territorial carbon sink and optimize its spatial pattern. However, there is a lack of understanding of the impact of environmental conditions and human activity on the vegetation’s carbon sequestration ability, especially in highly urbanized areas. For example, effective vegetation management methods can enhance vegetation Gross Primary Productivity, while emissions of air pollutants like O3, CO, NO2, and PM2.5 can suppress it. This paper mainly explores the factors influencing vegetation carbon sequestration capacity across different regions of Beijing. Based on remote sensing data and site observation data, this paper analyzed the spatiotemporal variation trend of Annual Gross Primary Production (AGPP) and the influence of environmental factors and human activity factors on GPP in Beijing from 2000 to 2020 by using the Theil−Sen’s slope estimator, Mann−Kendall trend test, and comparing Geographically Weighted Regression method (GWR) and Geographically and Temporally Weighted Regression method (GTWR). GWR is a localized multiple regression technique used to estimate variable relationships that vary spatially. GTWR extends GWR by adding temporal analysis, enabling a comprehensive examination of spatiotemporal data variations. Besides, we used land use cover data to discuss the influence of land use cover change on AGPP. The results showed that the spatial distribution pattern of GPP in Beijing was higher in the northwest and lower in the southeast, and it showed an overall upward trend from 2000 to 2020, with an average annual growth rate of 14.39 g C·m−2·a−1. From 2000 to 2020, excluding the core urban areas, the GPP of 95.8% of Beijing increased, and 10.6% of Beijing showed a trend of significant increase, concentrated in Mentougou, Changping, and Miyun. GPP decreased in 4.1% of the regions in Beijing and decreased significantly in 1.4% of the areas within the sixth ring. The areas where AGPP significantly decreased were concentrated in those where land use types were converted to Residential land (impervious land), while AGPP showed an upward trend in other areas. CO and NO2 are the main driving forces of GPP change in Beijing. O3 and land surface temperature (LST) also exert certain influences, while the impact of precipitation (PRE) is relatively minor. O3 and CO have a positive impact on AGPP as a whole, while LST and NO2 generally exhibit negative impacts. PRE has a positive impact in the central area of Beijing, while it has a negative impact in the peripheral areas. This study further discusses opinions on future urbanization and environmental management policies in Beijing, which will promote the carbon peak and carbon neutrality process of ecological space management in Beijing. Besides, this study was conducted at the urban scale rather than at ecological sites, encompassing a variety of factors that influence vegetation AGPP. Consequently, the results also offer fresh insights into the intricate nexus between human activities, pollutants, and the GPP of vegetation.

Recent Trends in Academic Vs Non-academic Radiologist Compensation and Clinical Productivity.

Recent radiologist compensation and clinical productivity trends have not been well characterized, especially across academic vs. non-academic practice settings. To assess recent trends in in financial compensation and clinical productivity between academic and non-academic settings in diagnostic (DR) and interventional radiology (IR). We studied deidentified data from the Medical Group Management Association (MGMA) for both DR and IR radiologists in academic and non-academic practices from 2014 to 2023. Median, 25th and 75th percentile, and mean values were analyzed for compensation, collections and work relative-value-units (wRVUs). Compensation and productivity data were compared by radiology subspecialty (DR vs IR), practice type (academic vs non-academic provider), geographical region of the US, and practice size. Trends in absolute changes were analyzed with linear regression. The MGMA Survey data for 2023 included responses for 3769 radiologists (2883 in DR and 886 in IR). In 2023, non-academic radiologists had greater total median compensation than academic faculty in both DR (by 27%) and IR (by 32%). From 2014 to 2023, median compensation increased faster for academic DRs (3.2% annually) than for non-academic DRs (1.9% annually). In 2023, DRs produced greater median wRVUs than IRs (by 53 % for non-academic and 46 % for academic radiologists) with higher collections, but IRs had higher compensation (by 16% in non-academic and 10% in academic settings). Over the last decade, IR physician compensation increased by 3.9% and 3.4% annually for non-academic and academic IR physicians respectively while median work RVUs trended downward (by -1.5 % for non-academic and -2.4 % for academic physicians) with declining collections (by -4.4 % annually for non-academic and -2.1 % for academic physicians). Over the last decade, the salary gap between academic and non-academic radiologists has narrowed. Physician compensation has increased at a faster pace in IR, despite relatively lower clinical productivity and declining collections.

This study examined the trends in cassava yield and production in the Kogi East Senatorial District of Kogi State, Nigeria, focusing on the perceptions of local farmers regarding yield changes over the past five years and the factors influencing these trends. A total of 403 respondents were surveyed, revealing that 71.3% of the farmers perceived an increase in cassava yields, while 28.7% reported stable yields. The primary factors contributing to the perceived increase included the use of improved cassava varieties (58.1%) and climate variability (41.9%). Furthermore, the statistical analysis indicated a stationary R-squared value of 0.792, suggesting a robust model fit for predicting future production trends. Forecasts indicated a steady increase in cassava production per hectare from 2024 to 2033, with projected yields rising from 17.33 tons per hectare in 2024 to 18.54 tons per hectare by 2033. Despite these positive trends, the study identified significant challenges posed by climate variability, with 76.7% of respondents recognizing a high impact on production. The findings underscore the urgent need for targeted interventions, including the promotion of climate-resilient cassava varieties, improved access to quality planting materials, and the implementation of sustainable agricultural practices. Overall, this study provides critical insights into the cassava production landscape in Kogi East and highlights the importance of collaborative efforts among stakeholders to enhance productivity and ensure food security in the region.

Narrowing the gaps between perception and adoption behavior of integrated pest management by farmers: Incentive and challenge

Integrated Pest Management (IPM) is an important strategy in global agriculture, aimed at maintaining the growth trend of food production without compromising environmental integrity or human health. Despite various measures taken by the government to encourage farmers to adopt IPM technologies, the adoption rate of IPM in China remains insufficient. This study finds that the number of farmers who adopt IPM to a high degree is significantly lower than those who view IPM as a win-win solution for profits and the environment. To address the gap between attitudes and behaviors, this research utilizes data from a survey of 480 households in Dengkou County, Inner Mongolia, China, employing structural equation modeling to analyze the impact of farmers' perceived factors on IPM adoption rates. Additionally, a generalized linear mixed model is used to assess farmers' attitudes toward financial subsidies, while an Ordered Logit model conducts an empirical analysis of the factors influencing barriers to IPM adoption. The findings indicate that: (1) Farmers' overly optimistic expectations regarding the initial costs of IPM hinder their adoption; (2) Farmers who are skeptical about the economic benefits of IPM demonstrate greater interest in cash subsidies; (3) Land characteristics and farmer attributes influence farmers' evaluations of barriers to IPM adoption. To develop reasonable and effective policies aimed at narrowing the adoption gap for IPM, it is essential to thoroughly understand the characteristics of farmers and their perceptions of IPM, and to design incentive measures that account for group differences. Findings of the study provide information regarding the IPM adoption gap among farmers in China, thereby offering practical insights and empirical evidence to assist policymakers in developing appropriate policies. It also provides a framework for countries in similar situations globally to examine and address the adoption gap.

Microwave‐assisted control of PtNi nanoalloy clusters on the nitrogen‐doped graphene oxide for energy conversion with oxygen reduction reaction and hydrogen evolution reaction

AbstractResearch on the production and utilization of hydrogen energy is essential to overcome the environmental issues caused by fossil fuels. Herein, we anchor PtNi nanoalloy clusters (Pt‐Ni NACs) on nitrogen‐doped graphene oxide (NrGO) by a facile microwave‐assisted synthesis and analyze the variations of catalyst properties based on the PtNi composition and the presence of nitrogen. Ni inclusion in the Pt matrix can induce lattice strain and change the electronic structure, while the doped nitrogen into the graphene can enhance electron transfer and improve the durability of the catalyst through strong chemical bonding with the alloy clusters. TEM analysis discovers that the NACs are uniformly decorated in a few‐nanometer‐size on the graphene surface, and the formation of the PtNi NACs and structural changes according to composition are confirmed through XRD and XPS. In addition, the structural changes due to N‐doping and its bonding with the NACs are observed through Raman spectroscopy and XPS. Electrochemical measurements reveal that Pt2.6Ni NACs/NrGO exhibits the highest ORR onset potential (0.893 V) and the lowest HER overpotential at 10 mA cm−2 (22 mV) among other catalysts, and those activities are almost unchanged under long‐term durability tests. From these results, Pt2.6Ni NACs/NrGO is utilized in a zinc‐air battery (ZAB) system, demonstrating better battery performance than commercial Pt and Ir‐based catalysts. Moreover, it is applied to hydrogen collection, showing linear trend in hydrogen production over time, confirming the catalyst's availability in hydrogen production and utilization.image

Retrospective analysis of prevalence and risk factors of bovine lameness in dairy farms in South Africa

Lameness is a crippling problem in the dairy industry, posing a significant welfare challenge and leading to premature culling. The study aimed to determine the seasonal prevalence of lameness in two different provinces of South Africa. The data was collected in two local municipalities (Mpofana and Raymond Mhlaba). However, the computer software systems of four randomly selected dairy farms were used to collect retrospective secondary data for lameness and predisposing factors (2018–2022). The data's targeted parameters include breed, parity, weight, stage of lactation, diseases diagnosed (lameness), age, and milk production trends. The highest prevalence was observed in uMpofana municipality (58.8%) compared to Raymond Mhlaba municipality (41.2%). Among cattle above nine years of age, the prevalence of lameness was the highest (36%), compared to 7-8-year-old (24%), 4-6-year-old (21.7%), and 1-3-year-old (14.3%) cattle. Additionally, the highest prevalence of lameness was observed during the summer season, followed by spring, winter, and autumn. The strongest association is kept for the right front leg (p<0.0001), followed by the left front leg (p<0.001), right back leg (p<0.001), and left back leg (p<0.001). In conclusion, this study provides baseline information on several key factors influencing the prevalence of lameness in dairy cattle in various farms in uMpofana municipality and Raymond Mhlaba municipality. The study findings could be used for farm managerial decision-making and epidemiological interventions. Given the high prevalence of lameness in dairy farms in uMpofana municipality, there is a need for more focused research aimed at identifying the specific causes of lameness in these localities.

Outcomes of Radiation Dose Reduction Protocol in Electrophysiologic and Cardiac Device Procedures

Background: Exposure to radiation has been demonstrated to be associated with adverse short- and long-term health outcomes. Objective: To presented outcomes before and after the implementation of a radiation dose reduction protocol in electrophysiologic (EP) and cardiac device procedures. Materials and Methods: The present study was a retrospective comparative study, conducted at Chiang Mai University Hospital in Thailand using 2017 and 2019 data, including all patients who underwent EP and cardiac implantable electronic device (CIED) procedures. Exclusion criteria involved patients with incomplete radiation dose records. The authors compared fluoroscopic time, radiation exposure, and complication rates before and after the protocol. Results: Among the 458 cases, with 214 Eps and 244 devices, the mean age was 58 years. For device implantation procedures, there was no significant change in fluoroscopic time as median (P₂₅, P₇₅) before and after protocol implementation were 3.1 (0.4, 5.8) versus 4.4 (1.2,7.6) minutes, respectively (p=0.117). However, there was a decreasing trend in dose area product (DAP) at 242.0 (119.2, 766.0) versus 197.9 (71.5, 494.5) cGy.cm² (p=0.073). The reduction in DAP was more pronounced in cardiac resynchronization therapy (CRT) implantation when comparing 2017 to 2019 were 1,933.6 (1,039.4, 7,683.8) versus 1,074.6 (427.2, 2,890.7) cGy.cm² (p=0.020). In EP procedures, fluoroscopic time significantly decreased from 8.1 (3.0, 14.3) minutes in 2017 to 1.0 (0.0, 3.6) minute in 2019 (p<0.001), accompanied by a significant reduction in exposure dose of 45.0 (10.8, 153.3) versus 1.7 (0.0, 31.6) mGy (p<0.001) and DAP of 1,022.9 (247.2, 2,660.3) versus 38.5 (0.0, 566.9) cGy.cm² (p<0.001). There was no difference in the complication rate between the two periods. Conclusion: The implementation of the radiation dose reduction protocol resulted in a significant decrease in radiation exposure during EP procedures and showed a trend towards reduction in CIED procedures.

ENVIRONMENTAL POLICY IN THE PUBLIC ADMINISTRATION SYSTEM: CHALLENGES OF SUSTAINABLE DEVELOPMENT

Sustainable development is a key topic on today's global agenda due to the threats posed by climate change, environmental pollution, and other ecological issues. Governments and international institutions aim to achieve a balance between economic growth, social welfare, and environmental protection. In this context, new technologies and support for green innovations, which have the potential to enhance environmental safety, play a particularly important role. Effective public administration must adapt to these challenges by actively implementing environmental policies and promoting sustainable development. International cooperation is also critical for integrating global commitments into national strategies. The purpose of this article is to demonstrate how environmental policy can support sustainable development through the improvement of the public administration system. The study provides a detailed analysis of international legal frameworks that regulate environmental policy and sustainability in public administration. Based on a systems approach, the complex interrelationships between government, society, business, and environmental factors are explored, allowing for a deeper understanding of how these elements interact. Using Switzerland as an example, one of the leading countries in environmental governance, the article identifies key elements for integrating environmental principles into public administration. This example demonstrates specific approaches and tools that other countries can adopt. Additionally, the statistics highlight not only global trends in plastic production and consumption but also the number of countries that have implemented environmental policy instruments between 2010 and 2023. This helps assess the scale of environmental initiatives at the global level. A SWOT analysis was conducted to assess the strengths and weaknesses of existing environmental policies, as well as to identify opportunities and threats for future development. This analysis helped outline the key directions for improving environmental policy to further support sustainable development. As a result, it was found that environmental policy within public administration has significant potential for growth, but its success depends on the establishment of an effective monitoring system, the intensification of international cooperation, the adoption of advanced technologies, and active public participation.
