Efficient magnetic solid-phase extraction, UPLC-MS/MS detection, and consumption assessment of five trace psychoactive substances.

Wastewater-based epidemiology (WBE) has become an objective and updated surveillance strategy for monitoring and estimating consumption trends of psychoactive substances (PSs) in the population. Firstly, magnetic shrimp shell biochar-based adsorbent (DZMBC) was synthesized and employed for extraction trace PSs from municipal wastewater. Proper pyrolysis temperature and increased KOH activator content favored the pore structure and surface area, thus facilitating extraction. DZMBC delivered exceptional extraction performance such as pH stability, anti-interference property, fast magnetic separation ability, reusability, and reproducibility. Then, a method based on magnetic solid-phase extraction (MSPE) followed by ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was developed, validated, and utilized for the quantitative determination of five PSs in real wastewater samples. Methodological validation results indicated a favorable linearity, low method limits of detection (1.00-4.75ng/L), and good precisions (intra-day and inter-day relative standard deviations < 4.8%). Finally, an objective snapshot of Chongqing drug use and consumption pattern was obtained. Methamphetamine (MAMP) and 3,4-methylenedioxymethamphetamine (MDMA) were the prevalent illegal drugs in local. Both concentrations and per capita consumption of MDMA displayed a change (P < 0.05) between July and September, while no statistical differences were observed for each week.

HydroFATE (v1): a high-resolution contaminant fate model for the global river system

Abstract. Pharmaceuticals and household chemicals are neither fully consumed nor fully metabolized when routinely used by humans, thereby resulting in the emission of residues down household drains and into wastewater collection systems. Since treatment systems cannot entirely remove these substances from wastewaters, the contaminants from many households connected to sewer systems are continually released into surface waters. Furthermore, diffuse contributions of wastewaters from populations that are not connected to treatment systems can directly (i.e., through surface runoff) or indirectly (i.e., through soils and groundwater) contribute to contaminant concentrations in rivers and lakes. The unplanned and unmonitored release of such contaminants can pose important risks to aquatic ecosystems and ultimately human health. In this work, the contaminant fate model HydroFATE is presented, which is designed to estimate the surface-water concentrations of domestically used substances for virtually any river in the world. The emission of compounds is calculated based on per capita consumption rates and population density. A global database of wastewater treatment plants is used to separate the effluent pathways from populations into treated and untreated and to incorporate the contaminant pathways into the river network. The transport in the river system is simulated while accounting for processes of environmental decay in streams and in lakes. To serve as a preliminary performance evaluation and proof of concept of the model, the antibiotic sulfamethoxazole (SMX) was chosen, due to its widespread use and the availability of input and validation data. The comparison of modelled concentrations against a compilation of reported SMX measurements in surface waters revealed reasonable results despite inherent model uncertainties. A total of 409 000 km of rivers were predicted to have SMX concentrations that exceed environmental risk thresholds. Given the high spatial resolution of predictions, HydroFATE is particularly useful as a screening tool to identify areas of potentially elevated contaminant exposure and to guide where local monitoring and mitigation strategies should be prioritized.

Income inequality of tribal households in Bangladesh: A decomposition analysis

This paper uses field survey data to examine farm and non-farm income to reduce income inequality among tribal households in Sylhet district, Bangladesh. It uses a decomposition method and a regression-based decomposition method to measure income and expenditure inequality by source of income as well as by household and family characteristics. For this, non-farm income was considered as an external transfer of total income to decompose the Gini index and as a potential substitute for farm income, taking into account household preferences. The results indicate that income differences exist between farm and non-farm income, thereby increasing income inequality. The endowment effect on household characteristics was positive and significant, directly supporting the increase in non-farm income per capita daily household expenditure. On the other hand, in terms of its components, non-farm self-employment income reduces income inequality, while non-farm wage income increases income inequality. At the 50th quantile results, an additional year of age of the household head increases the per capita expenditure of farm and non-farm households by BDT 300 to BDT 400, respectively. Moreover, the education of household heads also positively and significantly affects the per capita expenditure of non-farm households. As estimated by the 50th quantile, farm and non-farm households with graduation had higher per capita daily expenditure than household heads with primary education. Raising household education level and total farm household income to a better level, adopting farm-income enhancement programs, and enacting policies to increase alternative income opportunities that will shift income from non-agricultural to agricultural tribal households, reduce income inequality, and bring about the well-being of tribal society.

Understanding treatment of pain during SARS-CoV-2 pandemic in a two-year intercity longitudinal study using wastewater-based epidemiology

SARS-CoV-2 pandemic had a significant impact on the society, economy, and health of people around the world with consequences that need to be better understood for future pandemic preparedness. This manuscript provides insights into the usage of pharmaceuticals for pain treatment management throughout SARS-CoV-2 pandemic. Four towns and cities with a total population of > 1 million people covering an area of 2000 km2 in South West England were monitored for twenty-four months. Results showed different patterns in pain pharma usage, with small towns having higher population normalised daily loads (PNDLs) than big cities for majority of pain killers studied. This is likely due to demographics of these cities with smaller cities having older population. Per capita consumption of non-steroidal anti-inflammatory drugs (NSAIDs) increased compared to pre-pandemic usage in line with SARS-CoV-2 infections (ibuprofen and acetaminophen), while body pain drugs (diclofenac and naproxen) decreased in line with restrictions and closure of sports facilities. Changes in population normalised daily intake (PNDI) of pain killers were particularly apparent during the 1st and 3rd national lockdown. Comparison of PNDIs with prescriptions highlighted differences related to medication availability (OTC drugs) and patients’ nonadherence (prescribed drugs). In addition, several instances of direct disposal events across the catchments were observed which raises an issue of lack of pharma compliance and general understanding of potential environmental impacts from pharma usage.

Exploring Symbiosis: Innovatively Unveiling the Interplay between the Cold Chain Logistics of Fresh Agricultural Products and the Ecological Environment

Cold chain logistics are crucial for reducing agricultural product loss, yet the environmental impact of energy and packaging consumption, among others, demands attention, making the search for eco-friendly development modes essential. Based on data from 30 provinces in China from 2015 to 2021, this study analyzes the basic correlation between the development of cold chain logistics of fresh agricultural products (CCLFAP) and the ecological environment (EE) by using a random forest regression model in comparison with the XGBoost model. Correlation heatmaps were used to analyze the relationships between the cold chain logistics of fresh agricultural products and various factors of the ecological environment. The generalized additive model was then used to establish the connection between cold chain logistics and the ecological environment, identifying significant factors impacting EE. The results demonstrate that a higher development level of cold chain logistics corresponds to a better development trend of EE. The economic efficiency and technical aspects of cold chain logistics for fresh agricultural products are closely related to ecological pressures and responses. The number of employees in the logistics industry, the trading volume of fresh agricultural products, the number of refrigerated vehicles, and the capacity of the cold room have significant positive correlations with the ecological environment, while the per capita consumption of fresh agricultural products, the number of cold chain logistics patent applications, and the road density had significant negative correlations with the ecological environment. The effects of the number of cold chain logistics enterprises and the freight turnover of agricultural products transported by the cold chain on the ecological environment fluctuated. These findings contribute to reducing climate and environmental emergencies throughout the life cycle, offering sustainable development solutions for the fresh agricultural product cold chain logistics industry.

Acesulfame and other artificial sweeteners in a wastewater treatment plant in Alberta, Canada: Occurrence, degradation, and emission

Acesulfame (ACE), sucralose (SUC), cyclamate (CYC), and saccharin (SAC) are widely used artificial sweeteners that undergo negligible metabolism in the human body, and thus ubiquitously exist in wastewater treatment plants (WWTPs). Due to their persistence in WWTPs, ACE and SUC are found in natural waters globally. Wastewater samples were collected from the primary influent, primary effluent, secondary effluent, and final effluent of a WWTP in Alberta, Canada between August 2022 and February 2023, and the artificial sweeteners concentrations were measured by LC-MS/MS. Using wastewater-based epidemiology, the daily per capita consumption of ACE in the studied wastewater treatment plant catchment was estimated to be the highest in the world. Similar to other studies, the removal efficiency in WWTP was high for SAC and CYC, but low or even negative for SUC. However, ACE removal remained surprisingly high (>96%), even in the cold Canadian winter months. This result may indicate a further adaptation of microorganisms capable of biodegrading ACE in WWTP. The estimated per capita discharge into the environment of ACE, CYC, and SAC is low in Alberta due to the prevalent utilization of secondary treatment throughout the province, but is 17.4–18.8 times higher in Canada, since only 70.3% of total discharged wastewater in Canada undergoes secondary treatment.

Profitability and Feasibility of Onion Farming in The Lower Plains

Due to the increasing demand for shallots from households, companies, and industry, the per capita consumption rate of shallots is expected to increase by 8.21% in 2021, making shallots a high-value horticulture product with great business opportunities. Reok District is a subdistrict that is suited for cultivating shallots because it is situated in a lowland region at a height of 12 meters above sea level. 50% less land was cultivated than the previous year. Reok Sub-District is a center for producing shallots in Manggarai Regency, which is a basis for considering a selection of research locations. The decrease in planting area will have an impact on shallot production in Manggarai Regency. 50 shallot farmers, who were specifically selected as the samples, were added. With the assist of the income equation and R/C ratio analysis, this study seeks to ascertain the profitability and viability of shallot farming in Reok sub-district. Based on the analysis's findings, it was determined that shallot farming in Reok sub-district generated an average revenue of Rp. Rp32,304,679.04 with an average of 0.51ha, and the R/C ratio was 1.85, which indicated that the sub-district's shallot farming was deemed to be feasible. This research examines BEP unit and rupiah BEP as material for consideration in the implementation of agricultural activities in the next period in addition to revenue and business viability analysis. where the rupiah BEP is IDR 4,441.45/kg and the unit BEP is 1996.095 kg.

- Invited Review - Current status and future trends for pork production in the United States of America and Canada.

Pork production is a significant agricultural enterprise in the United States and Canada. The United States is the third-largest global producer of pork and Canada ranks seventh in pork production. The North American Free Trade Agreement and its successor, the U.S.-Mexico-Canada Agreement, have facilitated trade and integration between the two countries. The majority of production systems are modern and intensive, characterized by large vertically integrated farms using advanced technologies. Both nations benefit from their status as major producers of feed grains, with the United States leading in corn and soybeans, while Canada excels in canola and barley production. The regulatory frameworks for food safety, animal welfare, and environmental stewardship differ slightly, with the FDA and USDA overseeing these aspects in the United States, and Health Canada and the Canada Food Inspection Agency in Canada. The United States and Canada also have well-established distribution networks for pork products, relying on both domestic and international markets. Export markets play a crucial role, with the United States being a major importer of Canadian pigs, and both countries exploring opportunities in Asia. Despite a rise in global demand, domestic pork consumption trends differ, with per capita consumption remaining stable in the USA and declining in Canada. Changing consumer preferences, including a demand for ethically raised and locally sourced pork, may influence production practices. Future trends in pig production include a focus on consumer concerns, sustainability, disease prevention, reduction of antimicrobial use, and advancements in technology. The industry is adapting to challenges such as disease outbreaks and changing regulations, with a strong emphasis on animal welfare. Labor and workforce considerations, along with advancements in technology and automation, are expected to shape the efficiency of pork production in the future.

Replacing Natural Gas with Biomethane from Sewage Treatment: Optimizing the Potential in São Paulo State, Brazil

The search for cleaner and more sustainable energy sources is increasingly growing. Aligning this demand with another environmental problem, such as sewage treatment/disposal, is a strategic priority. In light of this, the aim of this study was to estimate the energy potential of sewage generated in the Brazilian state of São Paulo (SP) by using it to produce biomethane. The study also evaluated the viability of using this byproduct of sewage treatment (biomethane) as a substitute for natural gas (NG), as both of them have similar lower heat values. To do this, information was gathered regarding the population, gross domestic product per capita, sewage collected, and natural gas consumption for each of the state’s 645 cities, and, based on this, the sewage energy potential, the amount of NG to be substituted by biomethane, and the reduction in CO2 emissions were calculated. Moreover, in order to address a possible allocation of biomethane that could potentially be produced in each SP city and sent to currently NG-consuming cities, an optimization algorithm was proposed. The results indicated a sewage energy potential of 4.68 × 109 kWh/yr for the entire SP state, which would be enough to supply around 10% of the energy value of all the NG currently consumed. It was also observed that from 130 cities with NG consumption, 10 could produce enough biomethane to fully satisfy the natural gas demand. In the elected scenario of optimization, 291 cities were found to be capable of supplying the demand of 26 cities that currently use NG. The potential to reduce CO2 emissions is between 1.81 × 106 and 2.42 × 106 ton/yr, and this range could increase if sewage treatment coverage grows. Despite the challenges inherent in extrapolating a potential study to scenarios that require significative investment, the results obtained are useful for formulating public policies for decarbonization in the near future.

Food supply in the context of destabilization of the global economy

The goal is to analyze the state of food supply for the country's population in the context of destabilization of the world economy, inflation of prices for goods, primarily food, which in recent years have had a steady growth pattern. Methods – comparative analysis, economicstatistical, cause-and-effect. Results - the main signs of instability in economic situation in the world, their characteristics, main causes and consequences are revealed. The average annual growth rate of agricultural production for 2000-2020, 2020-2022 is shown and their impact on per capita supply of basic products and consumption rates. Comparison of these indicators allows to identify actual level of food support in Kazakhstan for specific years. The authors note that in the last two decades, physiological dietary and calorie standards for certain food products have not yet been achieved. Food security is also determined by the share of imports in consumer demand. Conclusions - it is recommended in the near and medium term to take effective measures to increase main types of products to volumes that will allow to move to import substitution and per capita consumption to the standards of physiological needs. Measures of state support to create favorable economic and organizational conditions for doing business in agricultural sector of the republic are proposed. Resolving food issue is recognized as the highest priority of government policy. The results of the study have practical significance for the organization and management of food supply system. It is important to promote the use of innovative technologies for production, processing, storage and rational use of food; formation of effective system for distribution of raw materials and agricultural products from producers to the final consumer; development of transport and warehouse infrastructure for wholesale trade.

Spatial Analysis of High-Tech Export Performance of the Eastern European Member States of the EU

Some Central and East European countries have integrated into the European Union after 2004 and followed free market economy principles. This paper studies the spatial spillovers effects of high-tech export, Gross Domestic Product per capita, research and development expenditure, number of research and development full time equivalent, and technology accumulation among European Union member Central and East European countries over the period 2007-2020 by using spatial panel estimation models. The main purpose of the paper is to investigate whether high-tech export of European Union member Central and East European countries has a dependency and interaction with each other after EU membership. The estimation results of spatial panel model results reveal that an increment in high-tech exports of adjacent countries increases the high-tech exports of other regional countries. Our results also provide evidence on Gross Domestic Product per capita, and research and development expenditure of European Union member transition economies have positive and significant impacts on high-tech exports of those countries.

Enhancing Older Household Consumption: The Impact of Long-Term Care Insurance in China.

Household consumption significantly affects the quality of life and successful aging of older adults. However, prior research has often overlooked the connection between household consumption and long-term care insurance (LTCI). This study aims to investigate the influence of LTCI on consumption patterns within older Chinese households. We used harmonized data from the China Health and Retirement Longitudinal Study and merged it with data from cities that implemented LTCI in China. We analyzed a total of 6,494 households consisting of individuals who were 60 years of age or older. To ensure accurate and stable research findings, we employed a series of difference-in-differences models. We found that LTCI has a significant impact on consumption levels, including total and per capita consumption within older households. Furthermore, our research demonstrates that LTCI significantly enhances enjoyable consumption across the consumption types. Through a heterogeneous analysis, it is shown that LTCI has a unique effect on both the total and enjoyable consumption of urban older households and also promotes comprehensive consumption improvements in older rural and disabled households. These findings highlight the crucial role of LTCI in improving the financial security and well-being of older households. They also have considerable policy implications for dealing with the challenges of an aging population.

Valuation of livestock population and national feed security to enhance livestock productivity in Ethiopia.

Feed is a major input in the livestock industry and covers about 60%-70% of the total cost of producing meat, milk and eggs. Inadequate feed supply in terms of quality and quantity leads to lower production performance in livestock. However, the development of an appropriate livestock production strategy through efficient utilization of existing feed resources could raise the production and per capita consumption of livestock products. Efficiency of feed resource utilization can be measured as the ratio between input to production activities and output (e.g. kg of protein used per unit of meat, milk and eggs produced or hectare of land used per unit of milk produced). This study was designed with the objective of evaluating the livestock population and national feed security to enhance livestock productivity in Ethiopia. To achieve this objective, data were collected from the websites of the Ethiopian Central Statistical Agency from 2007 to 2021, FAO publications and websites, books and journals. The data obtained on different feed resources, livestock population and livestock feed requirement and balance were entered into an MS Excel spread sheet (Excel, 2010) and analysed using the general linear model (PRO GLM) procedure of SAS (2014) and multivariate analysis of covariance. The study results revealed that the livestock population had increased from 58.31 million tropical livestock units (TLU) to 81.10 million tropical livestock units (TLU), and the emission of entericCH4 had increased from 2511.08 Gg/year to 3661.74 Gg/year from 2008 to 2021. The study results also showed that the major available feed resources for ruminants are natural pasture and crop residues, which account for 56.83% (87.56×106 ) and 37.37% (57.57×106 ) of total feed production in the country, respectively. The contribution of concentrate and improved cultivated pasture and feed from permanent crops used as feed sources is very insignificant (3.05% and 1.96%, respectively). The estimated quantity of these feed resources was sufficient to meet the livestock feed requirement in the country in terms of dry matter (DM), digestible crude protein (DCP) and MEJ, which estimated about 153.31×106 t, 4.56×106 t and 1203.97×109 MJ DM, DCP and MEJ, respectively. The estimated livestock feed requirements were 134.62×106 , 4.52×106 , and 918.83×109 in DM, DCP and MEJ, respectively. The supply covered about 114.33, 100.04 and 131.33% of the DM, DCP and MEJ total annual feed requirements of livestock in the country. Hence, the current feed surplus obtained on feed requirements of ruminants and equines can support the nutrient requirements of 500×106 broilers, about 5×106 bulls, about 50×106 small ruminants or 3×106 crossbred lactating dairy cows, yielding 10L of milk per day. The findings of study indicated that natural pasture and crop residues cover a major proportion of the annual feed supply in the country. Therefore, proper grazing management, feed conservation practices, improving grazing land vegetation through clearing invasive species, replacing the grazing land with an improved grass and legume mixture, effective collection, conservation and proper utilization of crop residues, and other alternative options such as the use of chemical, physical and biological treatments to improve the nutritive value of fibrous feed should be practiced. More effective extension services and farmer training are also required to increase feed productivity and, hence, human development.

Indonesian Happiness Factor: A Panel Data Analysis

The measurement of welfare level is one of the success benchmarks of a country's developmental program. Welfare assessments in the form of subjective well-being (SWB) can complement the objective measures. In assessing SWB, economists use happiness and life satisfaction questions. Therefore, this study aims to analyze the factors that influence individual happiness in Indonesia. The panel data from the last two waves of the Indonesia Family Life Survey (IFLS), namely IFLS 4 (2007) and IFLS 5 (2014) were used. The analytical tool was panel data regression with a fixed effect approach. The results showed religiosity, generalized trust, altruism, and education-age interaction significantly affected happiness levels. This study implies the higher the year of education, the more positive the effect of age on happiness level. Furthermore, the control variables, namely marital status, subjective health, perceived safety, and per capita expenditure are significant, while unemployment affected the happiness level of only the male sample. The government and public figures in Indonesia may promote initiatives that facilitate religiosity, trust, and altruism development, for instance, promoting activities that require involvement from different stakeholders in the community. They also should become role models showing altruism and religiosity.

Gender Inequality in Out-of-pocket Expenditure on Healthcare Among Persons with Disabilities in India

Background People with disabilities (PWDs) often face higher risk of financial burden towards healthcare. Higher out-of-pocket expenditure (OOPE) is a barrier towards accessing medical services, resulting in healthcare inequities between men and women. There is a lack of studies on gender disparities in healthcare burden among PWD in India. The present study examines gender inequality towards healthcare expenditure among PWDs in India. Methods Unit level data from the Persons with Disabilities in India Survey under the National Sample Survey, 76th round that covered 118,152 households involving 576,569 individuals of whom 106,894 had at least one disability was used. We performed secondary analysis using descriptive statistics, bivariate estimates, Blinder–Oaxaca decomposition and multilevel log-linear regression to meet the objective of the study. Results OOPE as a percent of monthly per capita expenditure was higher among males across all states of India except in Puducherry, Dadra and Nagar Haveli, Lakshadweep and Mizoram. This varied from 0.6% in Jammu and Kashmir to 20% in Nagaland. Multilevel analysis confirms that OOPE was significantly lesser among females ( β = –0.070, 95% confidence interval = – 0.129 to 0.01) compared to males after controlling demographic and disability-related predictors. PWDs reported higher healthcare burden as a percent of total household expenditure in India, and relatively less amount was spent on female healthcare compared to male healthcare. Conclusion A substantial gender inequality for healthcare expenditure is found among PWDs in India. This makes for an urgent call to health researchers and policymakers towards gender-sensitive research, policy formulation and program implementation for PWDs in India.

States' investment in recovery support services: An exploratory analysis

IntroductionRecovery support services (RSS), while not yet precisely defined, nevertheless have a longstanding role in managing chronic illnesses including substance use disorders (SUDs). This exploratory study is the first to identify the amounts of money that states invest from Substance Abuse and Mental Health Services Administration (SAMHSA) Block Grants; SAMHSA discretionary grant and state-appropriated sources; the types of organizations from which RSS are purchased; and the non-financial supports states provide for RSS. MethodsThe study is a mixed method exploratory analysis, based on three data sources: content analysis of all 51 (Washington, D.C. included) Substance Abuse Block Grant (SABG) state applications; in-depth interviews with a purposive sample of ten states and one territory; and a structured electronic survey sent to all SABG recipients. Forty states and 2 territories returned a total of 42 questionnaires from 56 possible states and territories (75%). Thirty-two of the responding states provided complete FY2022 financial data. ResultsStates reporting financial data spent $412 million from SABG, SAMHSA discretionary grants, and state appropriations for RSS. An estimate based on extrapolating regionally grouped per capita spending averages to non-responding state populations projected $775 million spent from these sources for all states. The study also calculated per capita and SUD prevalent population expenditures from these sources for each state. States purchase services from recovery community organizations and SUD treatment organizations in equal proportions, as well as from statewide recovery support organizations, educational institutions, hospitals, community health centers, and justice system organizations. Purchased services are not uniformly defined, but include community centers, peer staff, housing, and other support services. States provide non-financial support in forms that include technical assistance, community engagement, practice guidelines, and regulatory frameworks. ConclusionsThis first report of states' investments establishes a baseline to serve as a reference point for future analysis of these expenditures, as well as a foundation to which other sources of RSS funding such as Medicaid and other state and federal (e.g. HRSA, CDC, DOJ) dollars may be added. Uniform definitions for RSS will be necessary to support future reporting, accountability, and research. Finally, newly formed peer-based provider organizations need particular attention in order to be sustainable.

Wastewater-based estimation of diabetes mellitus prevalence in 237 cities: A cross-China study

Diabetes mellitus, a metabolic disease characterized by hyperglycemia, has been witnessed as a rapidly escalating worldwide health crisis. China currently had 140.9 million diabetic population in 2021, which was the largest globally. DM has witnessed a significant surge in the past few decades, leading to an alarming rise in the overall burden caused by this disease. To monitor the near real-time DM prevalence and the consumption of first-line anti-diabetic drugs, a wastewater-based epidemiology (WBE) approach based on the back-calculation of metformin concentration was implemented in 237 cities in China. The quantitative analysis of metformin in wastewater was conducted by LC-MS/MS with satisfactory results of method validation. The average concentration of metformin in wastewater was 14.07 ± 13.16 μg/L, and the per capita consumption was 5.16 ± 2.08 mg/day/inh, ranging from 0.90 to 10.36 ± 4.63 mg/day/inh. The calculated metformin prevalence was found to be 0.52 % ± 0.28 %, and the final estimated DM prevalence was 11.33 % ± 4.99 %, which was nearly consistent with the result of the International Diabetes Federation survey of 9.98 %. The results suggested that metformin might be one of the suitable WBE biomarkers in DM monitoring and WBE strategy could potentially enable the estimation of DM prevalence in most of Chinese cities after reasonable correction of associated parameters.

Strengthening the Blue Economy through Marine, Coastal Resources and the Social Environment

The fisheries sector is a sector which supports Indonesia’s development, because the waters in Indonesia are wider than the land. Central Java is a region that has a long coastline stretching along the north coast and the south coast of Java. This supports the development of fisheries potential in Indonesia. Research on the blue economy theme for the fisheries sector is being promoted. The method used is an analysis of economic aspects in Central Java, especially people engaged in fisheries (GRDP and income per capita), potential fisheries resources, human resource potential (number of fish fishermen and cultivators), fisheries households, as well as aspects of production and value fisheries production. The results of this research can provide an overview of the potential of fisheries in Central Java to facilitate their management. The research results show that GRDP in the fields of fisheries, forestry, and agriculture during the 2018-2022 period was 3.23%-7.33%; the highest per capita expenditure in the food sector is used to purchase food, and non-food cost is for housing and household facilities. The highest fish resource potential is a small pelagic fish. The most increased fisheries production in 2022 in the Central Java region will be in Rembang and Pati Regencies which have coastlines and are coastal areas.&#x0D; Keywords: fisheries, blue economy, coastal resources, marine resources

Profile of Broiler Chicken Farmers and Supporting Resources in Kepulauan Yapen Regency, Papua Province

Efforts to realize chicken meat consumption have not been achieved. Broiler chicken production in Kepulauan Yapen was about 7,379 and it was not comparable to the human population of 112,676 people. The per capita consumption of chicken meat in Kepulauan Yapen is still far from the national consumption of broiler chicken meat. The research uses descriptive methods with case study techniques. Data taken includes gender, age, education level, business scale, number of family members, farming experience, main job, and marketing channel. Data was obtained from farmers using questionnaires and from various related agencies of the Kepulauan Yapen. The collected data was analyzed using Minitab version 17 to obtain the average and percentage of each data obtained. Results of research showed that the majority of farmers who raise broiler chickens are male (81.82%), aged 15-65 years (100%), have a diploma or above education (45.5%), the scale of business is micro (100%), the number of family members involved in raising broiler chickens is 4 – 6 (54.5%), the farming experience is less than 10 years (100%), the main occupation is others such as trading, hunting (45.45%) and the marketing channel is from farmers directly to consumers.

Achieving carbon neutrality in Africa is possible: the impact of education, employment, and renewable energy consumption on carbon emissions

This paper analysed the causal link between education, employment, renewable energy consumption and carbon emissions in Africa, where there is scant evidence. Relying on panel data obtained from the World Development Indicators for thirty-two African countries covering a period of 19 years, and five panel rigorous regression models, we found that renewable energy, investment in education, school enrolment, net national income per capita, and employment had negative and significant effects on carbon emission, thus increasing these predictors would result in significant reduction in carbon emission in Africa. We identified a bidirectional causality between carbon emissions and net national income per capita, education expenditure and renewable energy consumption, and carbon emissions and employment. Our findings suggest that investment in education, renewable energy, and employment are relevant in mitigating carbon emissions in Africa. We recommend African governments to invest heavily in education, improve school enrolment, environmental education, renewable energy and employment provision to mitigate carbon emissions.Graphical
