Analysis of the Causes of the Decline in Water Production Bid on Fresh Water Generator in Ship MV. Lumoso Karunia II

This study aims to analyze the causes of the decline in fresh water production on the Fresh Water Generator on the MV. Lumoso Karunia II. Researchers conducted this research for 12 months and 5 days conducted on the MV. Lumoso Karunia II which is a type of Bulk Carrier ship which is a ship owned by PT Lumoso Pratama Line Company. This research method uses quantitative methods. Researchers use secondary data in the form of library books, journals and documents related to this research, while primary data in this study is in the form of direct field studies. Data collection techniques in this study are library research, direct and indirect observation and interviews. The results of this study indicate that the performance of the fresh water generator auxiliary aircraft is less than optimal so that what is produced does not match the amount of capacity due to lack of maximum maintenance. With the thickness of scale attached to the evaporator pipe of 1.85 mm, it causes blockage of the evaporator pipe. Thus, there is a decrease in intake in the evaporator. So, the decrease in intake in the evaporator resulted in a decrease in fresh water production of 16 m3 tons in the fresh water generator. As a result of the decrease in fresh water production in the fresh water generator at MV. Lumoso Karunia II is a shortage of fresh water in accommodation and disruption of the cooling process in machinery.

Comparison of immunoglobulin Y antibody production in new and spent laying hens.

Immunoglobulin (Ig)Y, a specific type of Ig found in chicken eggs, has potential use in the diagnosis of human and animal diseases. This study assessed the feasibility of using spent laying hens to produce IgY. In addition, the effects of antigen injection on egg and antibody production in new and spent laying hens were compared. Hens were intramuscularly injected with three booster shots of antigens. IgY was extracted from egg yolks using polyethylene glycol 6000 precipitation followed by dialysis. Spent laying hens (83 weeks) consistently showed lower egg production than new laying hens (27 weeks) throughout the study. Post-immunization, a further decline in egg production was observed in spent laying hens, and egg production stopped after the second antigen injection. Eggs from spent laying hens were less dense than eggs from new hens. Despite lower IgY levels in eggs from spent laying hens, the heavy-to-light chain ratio remained consistent in both groups. Notably, IgY from spent and new laying hens demonstrated effective hemagglutination against cat erythrocytes in the A blood group. This study demonstrated the potential of using spent laying hens to produce IgY, with significant implications for future research, immunotherapy, and diagnostic applications, despite the observed reduction in egg production compared with new laying hens.

The potential impact of legality requirements for China’s imported timber: a global forest product model‐based analysis

Utilizing the Global Forest Products Model (GFPM), this paper analyzes the potential impacts of China’s timber import legality requirement policies. Two alternative scenarios are compared with the baseline scenario: (1) China requires that imported timber must comply with the requirements of Verified Legal Compliance (VLC), (2) China imposes tighter requirements for imported timber, which must come from sustainably managed forests and meet Forest Certification (FC) requirements. The results show a decline in log production but an increase in processed wood exports to high‐risk countries, suggesting a move towards more valuable wood processing. Both high‐ and low‐risk countries are expected to see an increase in forest stocks. Welfare analysis indicates that high‐risk countries will benefit from industrial upgrades, while China might face welfare losses. Nevertheless, the enforcement of legal standards for timber imports into China is likely to enhance the perceived legitimacy of the sources of domestic timber materials, thereby facilitating the re‐entry of processed timber products into developed markets. This study proposes that China’s timber import regulations could offer mutual advantages, aiding in the fight against illegal logging and encouraging the legal timber trade.

A fast and reliable semi-analytical method for assessing energy replenishment from fracturing-flooding in low-permeability and tight oil reservoirs

The development of low-permeability and tight oil reservoirs is challenged by insufficient natural energy and rapid production decline. Fracturing-flooding is a technique that relies on high-pressure and large-volume fluid injection to replenish reservoir energy, making it a significant method for rapidly boosting formation energy. To evaluate the energy replenishment effect of fracturing-flooding technology in low-permeability and tight reservoirs, this study proposes a semi-analytical method for quick calculation. This approach employs dimensionless simplification, Pedrosa's substitution, Laplace transformation, and Stehfest inversion methods to derive pressure solutions for both the stimulation region and the external matrix region, each with varying flow capacities. The average formation pressure (AFP) of the reservoir is determined using the area-weighted average method, and numerical verification is performed using a commercial simulator. A case study from the Binnan area, along with a sensitivity analysis, demonstrates that after 30 days of fracturing-flooding, the AFP of the reservoir increases to 46.97 MPa, the corresponding reservoir pressure coefficient rises from 1.2 to 1.68, and reservoir energy increases by 40%. The factors influencing energy replenishment are ranked as follows: reservoir thickness, injection rate, stress sensitivity coefficient, matrix permeability, stimulation region radius, and mobility ratio. This study provides theoretical guidance for optimizing fracturing-flooding development schemes in low-permeability and tight oil reservoirs and offers valuable reference for the industry.

FRUITING BEHAVIOR AND FRUIT QUALITY OF LEADING MANGO CULTIVARS GROWN IN SOUTH PUNJAB-PAKISTAN

Mango is an important and exportable fruit crop of Pakistan However, it is being cultivated in Indo-Pakistan region from centuries, yet farmers face decline in mango production due to lack of available knowledge about fruit bearing habits of mango trees. In order to provide this basic information, a three year study plan was carried out on 10 elite varieties of mangoes from 2018-2020 in Punjab Pakistan. Data was statistically analyzed through R statistical programing using ANOVA analysis. The data depicts that cultivar Dusehri, Late Retaul, Sansation and Sufaid Chaunsa took maximum flowering on old shoots while Azeem Chaunsa, Kala Chaunsa, Langra, Sindhri and Anwar Retaul on new shoots. Fruit bearing on old shoots was significantly higher in Dusehri (75.80), while minimum on Azeem Chaunsa (0.0). The fruit bearing on new shoots was significantly higher on Anwar Retaul (99.73), while it was minimum on Dusehri (25.06). Significantly higher fruit weight was observed in Sufaid Chaunsa and total soluble solids were higher in Kala Chaunsa while minimum were observed in Sansation (15.93). Acidity was non-significantly different among the cultivars. Hence, it was concluded that Dusehri, Late Retaul, Sansation and Sufaid Chaunsa took maximum flowering on old shoots while Azeem Chaunsa, Kala Chaunsa, Langra, Sindhri and Anwar Retaul on new shoots. Our studies provide understanding of fruiting behavior which helps in devising mango crop’s varietal-specific management system and paves the way for mango’s quality and yield enhancement.

Drivers and Consequences of Land Degradation on Livestock Productivity in Sub-Saharan Africa: A Systematic Literature Review

Land degradation is a major threat to sub-Saharan Africa rangelands, which are crucial for livestock farming and the livelihood of millions of people in the region. This systematic review aims to provide a comprehensive understanding of the causes and effects of land degradation, as well as to evaluate the effectiveness of different mitigation strategies. Following the PRISMA guidelines, we identified, screened, and analyzed 25 peer-reviewed articles published before 30 June 2024 using Scopus. The review highlights key factors that drive land degradation, such as soil erosion, drought, deforestation, and climate change, as well as socio-economic factors like poverty, land tenure issues, population pressure, and economic instability. These factors have serious implications, as land degradation can lead to poor quality of forage, an increased incidence of diseases, higher mortality rates among livestock, and a significant decline in livestock productivity. The socio-economic consequences of this degradation are significant, leading to reduced household income, increased poverty, and heightened food insecurity. Furthermore, the review assesses various mitigation strategies and concludes that practices such as rotational grazing and soil conservation techniques demonstrate high effectiveness, while agroforestry practices show only moderate success. An integrated approach that combines environmental, economic, and policy measures is crucial to addressing the complex challenge of land degradation in sub-Saharan Africa. Strengthening land tenure, improving economic stability, and promoting sustainable agricultural practices are essential steps toward improving the health of rangelands, increasing livestock productivity, and supporting the resilience and well-being of rural communities.

The Tunisian Economics’ Situations After the Revolution of Arab Spring 2011

The Tunisian economic facts after the so-called the Arab spring or social revolution have been marketed by numerous fluctuations and radical changes in the general situation of the management of the administrative affairs of the country. The most prominent of these facts, including the series of chaotic sit-ins and the political and security instability that has increased from 2011 to 2018, note in particular the emergence of the phenomenon of terrorism and assassinations. These negative results are too the expensive cost of the Tunisian national economy, which has been directed, affected by all vital sectors of the country’s economy, especially the tourism, trade and investment sectors. In addition, the increase in excessive wages during the first three years following the revolution and the increasing number of random sit-ins that led to the cessation of the production in the Gafsa phosphate mine and the failure to work for most of the public servants represented negative factors that led to a decline in productivity and an increase in the financial and trade deficit. Thus, the budget deficit and the accumulation of indebtedness represent the main obstacle to achieving social and economic stability.

Addressing multidimensional highly correlated data for forecasting in precision beekeeping

In recent years, there have been relevant advances in precision beekeeping. These advances are mainly focused on proposing sensor systems that collect crucial information for bee welfare, creating integrated architectures that allow beekeepers to monitor the current state of their hive through real-time data. However, there is a lack of predictive models that would allow beekeepers to anticipate specific events that endanger bee welfare and lead to a decline in productivity. Specifically, predictive approaches accounting for the high correlation among internal variables of beehives have not been developed to date. To address this research gap, multivariate predictive models, including auto-regressive state-space and time series models, have been implemented and applied to four different hives from the we4bee project. These models aim to predict the internal variables of beehives (four different temperatures, humidity, and weight) by utilizing the meteorological conditions to which the hives are exposed. A cross-validation adapted to time series data was employed for model generalization assessment. Prediction models based on vector time series exhibited superior performance in forecasting internal hive variables compared to multivariate auto-regressive state-space models. Overall, the approach based on the vector error correction model yielded the best balance between fit, prediction, and computational cost. The VEC-based approach produces predictions with maximum mean absolute errors of 177 (312)g in weight, 3.366 (3.802)% in humidity, and 1.122 (1.685)°C in temperature at 1 (3)-days ahead when dealing with beehives exhibiting a high degree of correlation in their internal variables. Moreover, the VEC-based approach requires less than a second to perform the time series fitting process, which makes it particularly interesting for application in big data environments. The integration of such models into a decision support system would meet the need of beekeepers to anticipate potential threats to the welfare of their bee colonies, streamlining their monitoring processes while eliminating the need for continuous inspections.

Narrativizing the Nexus between Climate Crisis and Immigration in Amitav Ghosh's Gun Island: An Ecocritical Exploration

Eco-criticism is a branch of literary scholarship that finds tangible connections between the environment and literature. The environmental problem is one of the most prominent issues of current generation. Climate crisis stands as a sole factor in the environment in view of ecological imbalance. This is an ever increasingly presence in our daily lives. prominent causes of climate change are an increase of green house gasses, deforestation to develop human settlements, excessive use of fossil fuels and so on. Decline in agricultural productivity is another impact of climate change. Thus, this is widely recognized as a contributing and exacerbating factor in immigration. The climate crisis, migration and refugees' acute situation have allegedly lost security and stability of humans and non-humans. The paper attempts to look how Amitav Ghosh has put his best endeavors to discover the inordinate use of nature by human beings. The materialistic and anthropocentric attitudes of human beings undergo extreme climate crisis and the displacement of livings. Now, the major environmental issues become the ethical concerns in the eco pages of literary writers to highlight the problems of ecosystem. The novel "Gun Island" deals with the issue of climate crisis and immigration. Planetary environmentalism identifies the planetary crisis caused by climate change. It seeks environmental justice both for humans and nonhumans across the planet. The whole planet goes beyond geographical boundary because of threatening of climate change. Ghosh in this novel wants to procure awareness among the readers regarding the impending calamities of the global environment and thus a warning to mend exploitative attitudes towards our Mother Nature.

Experiments on Steam-Assisted Gravity Drainage with Coinjection of Noncondensable Gases during the Middle and Later Stages of Its Development in Super-Heavy Oil Reservoirs

Summary The problems of oil/steam ratio (OSR) and oil production decline are prominent during the middle/later stages of steam-assisted gravity drainage (SAGD) in superheavy oil reservoirs. Using noncondensable gas (NCG) by SAGD can reduce heat loss to the overburden and reduce carbon dioxide (CO2) emissions. However, to date, laboratory experiments have mainly been conducted to simulate NCG coinjection with steam in the early stage of SAGD. There has been limited research on the NCG coinjection into the mature SAGD steam chamber. For this study, five sets of 2D physical simulation experiments are introduced and designed based on NCG coinjection with steam into the sand-packed model. The influencing factors of steam-assisted and gas push (SAGP) are analyzed through experiments, including different NCGs [methane (CH4), CO2, and nitrogen (N2)] and coinjection of NCG at different times (i.e., during the lateral expansion and descending stages of the steam chamber). The results indicate that the mechanism of SAGP includes reducing the steam consumption, maintaining the pressure balance of the steam chamber, reducing the partial pressure of the steam, maintaining the quality of the steam, and improving the displacement efficiency of the steam during the lateral expansion of the steam chamber. In addition, the top gravity displacement is the primary mechanism during the later stage of pure gas injection, which manifests that the residual oil at the bottom of the steam chamber is further recovered by using the residual heat of the the steam chamber. Compared with SAGD, the recovery of CO2-assisted SAGD (CA-SAGD), CH4-assisted SAGD (MA-SAGD), and N2-assisted SAGD (NA-SAGD) increased 6.8%, 5.4%, and 4.4%, respectively. The NCG coinjection effect was better during the descending stage of steam chamber, and the oil recovery was 4.7% higher than that during the lateral expansion stage. The selection of NCG and coinjection timing plays a crucial role in improving the ultimate oil recovery and OSR during the middle and later stages of SAGD in superheavy oil reservoirs.

Responses of coastal phytoplankton communities to seasonal herbicide inputs: Tolerance or degeneration?

Herbicide-induced phytoplankton inhibition threatens coastal biodiversity and ecosystem function. Although studies employing single-frequence exposure aid in understanding the phytoplankton community's responses to herbicides, it’s difficult to objectively assess their response to cyclic herbicide inputs (long-term low-dose and short-term high-dose) in marine ecosystems. Here, we analyzed the concentration and distribution of herbicides in global coastal waters and simulated this cyclic process through a two-phase atrazine exposure mesocosm experiment and laboratory tests. The results indicated that, the herbicide concentrations (0.82 nmol L−1, 95 % CI 0.55, 1.74) from May to August were significantly higher than that (0.14 nmol L−1, 95 % CI 0.02, 0.38) in the remainder months, and highest concentrations typically emerged in summer; the changes in phytoplankton community composition under environmental concentrations of triazine herbicides could recover in the short term, but sustained inhibition of biomass was produced; the dominant populations were more likely to develop tolerance through preexposure and recover from subsequent impulse of atrazine, but this process was accompanied by the loss of rare groups and a decrease in biodiversity, meanwhile, affected the bacterial community in phycosphere. Consequently, we considered that the cyclic herbicide inputs may cause more detrimental effects than single-frequence exposure, potentially leading to a large-scale decline in coastal primary productivity.

Rad6 Regulates Conidiation by Affecting the Biotin Metabolism in Beauveria bassiana.

Rad6 is a canonical ubiquitin-conjugating enzyme known for its role in regulating chromosome-related cellular processes in yeast and has been proven to have multiple functions in Beauveria bassiana, including insect-pathogenic lifestyle, UV damage repair, and conidiation. However, previous studies have only reported the key role of Rad6 in regulating conidial production in a nutrient-rich medium, without any deep mechanism analyses. In this study, we found that the disruption of Rad6 leads to a profound reduction in conidial production, irrespective of whether the fungus is cultivated in nutrient-rich or nutrient-poor environments. The absence of rad6 exerts a suppressive effect on the transcription of essential genes in the central developmental pathway, namely, brlA, abaA, and wetA, resulting in a direct downregulation of conidiation capacity. Additionally, mutant strains exhibited a more pronounced decline in both conidial generation and hyphal development when cultured in nutrient-rich conditions. This observation correlates with the downregulation of the central developmental pathway (CDP) downstream gene vosA and the upregulation of flaA in nutrient-rich cultures. Moreover, single-transcriptomics analyses indicated that irregularities in biotin metabolism, DNA repair, and tryptophan metabolism are the underlying factors contributing to the reduced conidial production. Comprehensive dual transcriptomics analyses pinpointed abnormal biotin metabolism as the primary cause of conidial production decline. Subsequently, we successfully restored conidial production in the Rad6 mutant strain through the supplementation of biotin, further confirming the transcriptomic evidence. Altogether, our findings underscore the pivotal role of Rad6 in influencing biotin metabolism, subsequently impacting the expression of CDP genes and ultimately shaping the asexual life cycle of B. bassiana.

Assessing the Value of a Human Life in Heat-Related Mortality: Lessons from COVID-19 in Belgium

This study evaluates the cost of heat-related mortality using economic impacts and mortality data from the COVID-19 pandemic in Belgium as a proxy. By examining the economic loss measured by gross domestic product (GDP) decline and excess mortality during the first COVID-19 wave (March–June 2020), a new estimate for avoided heat-related mortality is derived. The results show that the cost per avoided death is EUR 377,000 ± EUR 222,000, significantly lower than numerical values of the commonly used Value of a Statistical Life (VSL). However, when this cost is divided by the expected remaining (eight) life years at the age of death, the resulting monetary value for a saved life year, in a EUR 47,000 ± EUR 28,000 range, aligns well with commonly used values for the Value of a Life Year (VOLY). Thus, the present study contributes to the ongoing debate on the most appropriate methods for valuing human life in the context of heat-related mortality. By comparing our results with both VSL and VOLY, we underscore the limitations of VSL in the context of heat-related mortality and advocate for VOLY as a more accurate and contextually relevant metric. These findings may offer useful insights for policymakers in evaluating and prioritizing investments in heat-related mortality-prevention strategies.

Elevated CO2 and Nitrogen Supply Boost N Use Efficiency and Wheat (T. aestivum cv. Yunmai) Growth and Differentiate Soil Microbial Communities Related to Ammonia Oxidization.

Elevated CO2 levels (eCO2) pose challenges to wheat (Triticum aestivum L.) growth, potentially leading to a decline in quality and productivity. This study addresses the effects of two ambient CO2 concentrations (aCO2, daytime/nighttime = 410/450 ± 30 ppm and eCO2, 550/600 ± 30 ppm) and two nitrogen (N) supplements (without N supply-N0 and with 100 mg N supply as urea per kg soil-N100) on wheat (T. aestivum cv. Yunmai) growth, N accumulation, and soil microbial communities related to ammonia oxidization. The data showed that the N supply effectively mitigated the negative impacts of eCO2 on wheat growth by reducing intercellular CO2 concentrations while enhancing photosynthesis parameters. Notably, the N supply significantly increased N concentrations in wheat tissues and biomass production, thereby boosting N accumulation in seeds, shoots, and roots. eCO2 increased the agronomic efficiency of applied N (AEN) and the physiological efficiency of applied N (PEN) under N supply. Plant tissue N concentrations and accumulations are positively related to plant biomass production and soil NO3--N. Additionally, the N supply increased the richness and evenness of the soil microbial community, particularly Nitrososphaeraceae, Nitrosospira, and Nitrosomonas, which responded differently to N availability under both aCO2 and eCO2. These results underscore the importance and complexity of optimizing N supply and eCO2 for enhancing crop tissue N accumulation and yield production as well as activating nitrification-related microbial activities for soil inorganic N availability under future global environment change scenarios.

Study on fluid phase behavior characteristics of low permeability reservoir under different CO2 injection amounts

M reservoir is a low peremeability reservoir located in northwest China. Currently, it faces the problem of difficult water injection, low single well production, and rapid production decline. CO2 flooding technology is considered to be implemented to solve these problems by effectively supplementing formation energy. Considering that the phase behavior of reservoir fluid during CO2 injection and its influence on the development effect are complex, the PVT test experiment of reservoir fluid is carried out to analyze the variation of reservoir fluid properties under different CO2 injection volumes. The experimental results show that the saturation pressure, solution gas-oil ratio, volume coefficient and expansion coefficient of crude oil increase with the increase of CO2 injection, while the viscosity and density of oil continue to decrease. When the CO2 injection amount reaches 32 %, the dissolved gas-oil ratio increases from the original 36.2 m³/m³to 150.2 m³/m³, the viscosity of the formation oil is reduced by about 76 % than before CO2 injection; and the volume of crude oil has expanded to 1.28 times of that without CO2 injection. Moreover, the P-T phase diagram is drawn and the influence of CO2 injection on the distribution of phase regions in the phase diagram and the critical parameters of oil is analyzed. The high pressure physical properties of reservoir fluids at different CO2 injection volumes are obtained, which can provide a good foundation for the study of enhancing oil recovery by CO2 injection in M reservoir.

Experimental and theoretical insight into the use of maleic anhydride copolymer and modified sulfamic acid for removing oilfield blockage

In the process of oil production, the problem of oilfield production decline due to blockage is becoming more and more serious. To improve the exploitation efficiency of traditional fuel, it is very important to remove the blockage and inhibit the formation of the blockage. In this study, the primary constituents of the blockages in this oilfield were identified as asphaltene (organic blockage) and calcium carbonate (CaCO3, inorganic blockage). To address these blockages, maleic anhydride copolymer (MAC-1, MAC-2, and MAC-3) with different chain lengths were polymerized by maleic anhydride and allyl polyoxyethylene ether, which were used to disperse organic blockages. Additionally, modified sulfamic acid (MSA-1, MSA-2, and MSA-3) with different chain lengths were synthesized by sulfamic acid, polyethylene glycol, and lauroyl chloride, which were used to dissolve inorganic blockages. The efficacy of these agents in terms of blockage removal, scale inhibition capability, corrosion rate, and compatibility with formation water were comprehensively evaluated. Results showed that MAC-2, which possesses a moderate chain length, and MSA-1, which has a shorter chain length, demonstrated an optimal synergistic effect on blockage dissolution at concentrations of 4 wt% for MAC-2 and 5 wt% for MSA-1. The dissolution rate of this combination was 81.18 %, with a scale inhibition rate of 95.7 %. The corrosion rate increased with temperature, and the agents maintained good compatibility with the formation water. To elucidate the mechanism underlying the effectiveness of MAC, the interaction between MAC and asphaltene was simulated by molecular dynamics (MD). These simulations indicated that MAC-2 and asphaltene exhibit the highest interaction energy (-64.2618 kcal/mol). Furthermore, we investigated the dissolution kinetics of CaCO3 in MSA solutions and determined that the reaction between MSA and CaCO3 was first-order, with a reaction rate constant of 1.6 × 10−2 min−1. The insights gained from this study offer a valuable experimental and theoretical foundation for enhancing productivity in similar oilfields.

Unveiling Wheat’s Future Amidst Climate Change in the Central Ethiopia Region

Quantifying how climatic change affects wheat production, and accurately predicting its potential distributions in the face of future climate, are highly important for ensuring food security in Ethiopia. This study leverages advanced machine learning algorithms including Random Forest, Maxent, Boosted Regression Tree, and Generalised Linear Model alongside an ensemble approach to accurately predict shifts in wheat habitat suitability in the Central Ethiopia Region over the upcoming decades. An extensive dataset consisting of 19 bioclimatic variables (Bio1–Bio19), elevation, solar radiation, and topographic positioning index was refined by excluding collinear predictors to increase model accuracy. The analysis revealed that the precipitation of the wettest month, minimum temperature of the coldest month, temperature seasonality, and precipitation of the coldest quarter are the most influential factors, which collectively account for a significant proportion of habitat suitability changes. The future projections revealed that up to 100% of the regions currently classified as moderately or highly suitable for wheat could become unsuitable by 2050, 2070, and 2090, illustrating a dramatic potential decline in wheat production. Generally, the future of wheat cultivation will depend heavily on developing varieties that can thrive under altered conditions; thus, immediate and informed action is needed to safeguard the food security of the region.

Factors Affecting the Innovation of Crop-Livestock Integration System (SITT) Adoption in North Minahasa Regency

The adoption of beef cattle crop-livestock integration system (SITT) innovations in North Minahasa Regency still faces various obstacles. As a result, beef cattle development tends to experience a decline in population, productivity, and competitiveness. The purpose of the study was to determine the factors influencing farmers' attitudes and adoption of SITT technology innovations for beef cattle in North Minahasa Regency. Mixed-method research was conducted from March to May 2024, where 25 extension agents and cattle farmers were selected purposively. The variables used were farmer characteristics, extension worker performance, nature of innovation, communication channels, attitudes, and farmer adoption of SITT. Data analysis used the Spearman rank method. The study revealed a strong correlation between extension worker performance and the nature of innovation on farmers' attitudes and SITT adoption. In contrast, communication behavior exhibited a negligible impact. These findings underscore the critical role of extension agents in facilitating technology adoption. To maximize the effectiveness of extension programs, efforts should focus on enhancing extension worker capabilities and creating innovative solutions tailored to farmers' needs.

Review: Impact of food safety on global trade.

Food safety encompasses the supply and assurance of safe, high-quality food for consumers. It is a crucial aspect of food security, gaining greater global attention due to the increasing number of widespread foodborne incidents. International trade is expanding as countries increasingly rely on each other to secure a sufficient and diverse food supply. Beyond this, concerns about food safety have become more prevalent due to various factors. Therefore, this review aims to investigate the effects of food safety-associated risks on the international trade of food and related products. A total of 37 published studies retrieved using different search engines were included in this review. This review revealed that because of rapid population growth and rising food demand in developing nations, agricultural intensification is growing. It has been found that foodborne illnesses and associated discrepancies can impede the international trade of food commodities. Trade bans due to the fear of foodborne illnesses are growing. The consequences of foodborne diseases are multifaceted and include financial losses from trade restrictions, medical costs for prevention or control, resource depletion and a decline in food production. The overall effects are increased international trade tensions and livelihood vulnerability to poverty, notably for small-scale livestock producers. Potential food contaminants include microbes, pesticides, pharmaceutical residues, heavy metals and fraudulent such as improper food processing, mislabelling, poor packaging, adulteration and substitution. Hence, countries are encouraged to harmonize the rights and duties set by the World Trade Organization under sanitary and phytosanitarys to maximize their advantages in global markets. Based on this evidence, we recommend that each country develop and integrate regulations that would ensure the safety of both domestic and international food production systems. Furthermore, the global community should either revise the current functioning food regulatory and monitoring body or establish a more genuine collaborative network.
