ABSTRACT

Efficiency in shrimp farming is due to the use of an extensive system that includes fewer larvae per pool, which increases productivity, improves financial results, and even the environmental impacts generated during these operations. The objective of this study was to identify the factors that affect supply in the Ecuadorian shrimp sector. To this end, some statistical techniques such as linear regression and hypothesis testing were used. A bibliographic study was carried out regarding shrimp production in Ecuador, taking as reference the data provided by the National Chamber of Aquaculture and public control entities and reviewing the unprecedented impact on the current COVID19 sanitary crisis and the reduction of shrimp demand affecting Ecuador's income. Finally, it was observed that the research variables considered directly impact crustacean production, and a mathematical model was established.

ABSTRACT

The macroeconomic evolution since the beginning of 2022, worldwide, but also at regional and national level, marks major imbalances, caused by several factors, among which the vulnerability of the energy system as a whole is a major one. Demand and supply in all forms of energy, both in terms of production and distribution, have unsustainable gaps, which implies the need the need for public authorities to intervene through the design and implementation of appropriate strategies to address the challenges of the transition in energy resources and, at the same time, to remove the effects of the crisis of the energy system, a crisis that is felt in the vast majority of the states of the world.

ABSTRACT

This study attempts to present a contribution of Blockchain Technology (BC-T) in managing disruptions, and risk caused by the COVID-19 outbreaks and extending profound support in developing resilient Food Supply Chains (FSCs). The effects of the pandemic can be witnessed on global supply chains in their demand & supply side disruptions and in the changing patterns of consumer buying in the food industry. The assessment of the disruptive factors is required to explore the present issues and promising resilient strategies to impart robustness to the FSCs for mitigating disruptions in the future. An integrated approach of Fuzzy Analytic Hierarchy Process (FAHP) and Weighted Assessment Sum Product Assessment (WASPAS) is employed to assess the factors related to sourcing, lean, workforce, and flexibility, as well as evaluation of the BC-T enabled FSCs resilient strategies that mitigate the effect of disruption during the pandemic. The findings exhibit that ‘Sourcing related’ is the most affecting disruptive factor causing distress in the FSCs and ‘flexibility resilient strategy’ is the most relevant resilient strategy for BC-T enabled FSCs. The BC-T acts as a catalyst in enhancing the flexibility, traceability, and shorter supply chain network structure that may help the FSCs to mitigate risk and disruption in the pandemic situation. The BC-T helps the FSCs to control the demand and supply shocks, and supports the organization with real-time monitoring and sharing information. This study provides insights to the decision-makers, managers, and other stakeholders to take significant decisions during an emergency.

ABSTRACT

In this study, the effects of the pandemic, which started to affect the world to 2019-December, on the world aquaculture sector were evaluated with SWOT analysis (opportunities, benefits, and threats). Previous studies on this subject were scanned using certain keywords (COVID-19, pandemic, coronavirus, fishing, fisheries), and a total of 33 studies were listed. Previous studies were classified according to the sub-areas (continents) determined by FAO. The effects of the pandemic on the sector were tried to be determined according to the continents. Accordingly, the threats on a global scale were supply-demand imbalances, closure of restaurants, storage inadequacies, plastic pollution, closure of borders, illegal fishing, inequalities in the sector, and curfew restrictions. The opportunities;creation of new supply chains, raising awareness about the seafood that positive effect on health, establishing a supply-demand balance, granting work permits to fishermen during curfews, allocation of funds to be used in extraordinary situations such as pandemics, development of aquaculture, implementation of measures for the continuity of import-export, providing economic aid packages to vulnerable sector workers such as small scale fisheries, limiting the sexist understanding in the sector, and giving more opportunities to women, and cooperation with riparian countries to prevention of illegal fishing. Its benefits are listed as prevention of overfishing in the short term, protection of fish stocks, reduction of industrial pollution in the aquatic ecosystem, adoption of an ecosystem-based fishing approach in small settlements, and an increase in recreational fishing. As a result of this analysis, it has been understood that we may create accurate and fair international cooperation to solve the adverse effects of pandemia. With this gained experience, it is thought that new production strategies should be developed for trustable food supply chains in the changing world.

ABSTRACT

The fragility of global food supply chains, which signals food shortages and increases in food prices in recent years, has reached the highest level with the government's lockdown measures during the COVID-19 pandemic. The study aims to highlight the disruptions in global food supply chains brought about by the ongoing COVID -19 pandemic and present the impact of these disruptions on food security. Supply-side and demand-side shocks that bring about deterioration of the flow in food supply chains and disruptions that threaten food security have made access to adequate and nutritious food an issue as significant as the pandemic. In the food supply chain, panic-oriented buying behaviors by consumers, job and income losses due to changes in labor markets and inflation have occurred as demand-side effects. Labor shortages, disruptions in transportation networks, restrictions imposed by countries, the opportunities of digital technology, and the spread of e-commerce have emerged as supply-side effects. The COVID-19 pandemic has caused negative effects on food security, jeopardizing availability, access, utilization, and stability with supply-side and demand-side shocks. In the conclusion part of the study, the resiliency of food systems, automation of food supply chains, the safety of employees and the importance of monitoring supply chain activities in online environments, the social security policies and practices of the state for vulnerable groups experiencing food insecurity, and food sovereignty were discussed.

ABSTRACT

Ecosystem service spatial transfer is considered a feature that can deliver ecosystem services at a distance to meet the demands in areas with uneven spatial distribution of natural and social economic development. The natural ES spatial transfer distance and intensity were simulated by using the modified breaking point model in the Central Plains urban agglomeration (CPUA) with the cities of Luoyang, Zhengzhou, Shangqiu, and Huaibei stretching across. It is shown that there is a spatial mismatch between ES supply from ecospace and its demands from cities;relying only on natural spatial transfer, none of the ESs of the ecospace can be transported to corresponding population centers;and a spatial gap between ES supply and demand is illustrated in urban agglomeration areas. Intercity cooperation in ecosystem management and landscape planning based on ES spatial transfer would be good choices for cities, giving full play to comparative advantages to achieve sustainable development for the entire CPUA.

ABSTRACT

This essay offers a small state perspective on US-China rivalry in the post-COVID-19 era. After tracing the emergence of the "twin chessboards" of big power rivalry, namely, high and low politics competitions, the essay assesses the impact of these competitions on the post-pandemic Asian order, with a focus on Southeast Asia. I argue that while US-China competition has been rising rapidly in high politics (that is, in the military field), the increasing importance of low politics—infrastructure and connectivity development, technology, trade, finance, public health, and other functional areas—is shaping the prospects, pace, and patterns of the onset of Cold War 2.0. The intensified US-China animosity across the twin chessboards is widening the scope of the competition, increasing the number of players, and mounting pressure on all smaller states. Arguably, however, it is also providing these smaller states with more maneuvering space. These developments reshape geostrategic supply and demand in Southeast Asia. Accordingly, the smaller states are developing additional layers of partnerships with actors near and far, thereby broadening their hedging options in an increasingly uncertain and high-stake environment.

ABSTRACT

This article talks about the impact of COVID-19 to the Canadian pulp market. The situation surrounding the pulp market is presented, where in 2019, the pulp and paper market in Canada has been tightening due to unexpected downtime and excess inventories returning to a more balanced level. China on the other hand has been slowly getting industrial operations started again after a mandatory quarantine period and travel ban brought the country to a halt. In North America, consumers have been panic buying and stockpiling household products including bath tissue for weeks, leading to shortages at major retailers like Costco and Walmart. While psychologists call the hoarding ritual in times of crisis natural, it's led to empty shelves and frustrated shoppers. Tissue producers are now ramping up to meet the demand - but the extra capacity might be a short-term silver lining. With the news about COVID-19 changing almost hourly, the markets remain uncertain and difficult to predict. Canadian pulp and paper mills, especially those in British Columbia, are particularly challenged during this unprecedented time because of the fibre shortages and very low pulp prices.

ABSTRACT

Access to vaccination against a health threat such as that presented by the COVID-19 pandemic is an imperative driven, in principle, by at least three compelling factors: (1) the right to health of all people, irrespective of their status; (2) humanitarian need of undocumented migrants, as well as of others including documented migrants, refugees and displaced people who are sometimes vulnerable and living in precarious situations; and (3) the need to ensure heath security globally and nationally, which in the case of a global pandemic requires operating on the basis that, for vaccination strategies to succeed in fighting a pandemic, the highest possible levels of vaccine uptake are required. Yet some population segments have had limited access to mainstream health systems, both prior to as well as during the COVID-19 pandemic. People with irregular resident status are among those who face extremely high barriers in accessing both preventative and curative health care. This is due to a range of factors that drive exclusion, both on the supply side (e.g., systemic and practical restrictions in service delivery) and the demand side (e.g., in uptake, including due to fears that personal data would be transmitted to immigration authorities). Moreover, undocumented people have often been at increased risk of infection due to their role as "essential workers", including those experiencing higher exposure to the SARS-CoV-2 virus due to frontline occupations while lacking protective equipment. Often, they have also been largely left out of social protection measures granted by governments to their populations during successive lockdowns. This article reviews the factors that serve as supply-side and demand-side barriers to vaccination for undocumented migrants and considers what steps need to be taken to ensure that inclusive approaches operate in practice.

ABSTRACT

The pandemic of Covid-19 has resulted in more significant global problems in terms of food security due to movement control orders (MCO) executed around the world. Malaysia has been affected by the Covid-19 pandemic and has slowed down the activities of economic sectors, including the agriculture sector. Therefore, this paper discussed in depth the impact of the Covid- 19 pandemic on food security in Malaysia, especially in terms of food supply and demand. This study used qualitative method involving analysis of formal and informal documents to obtain information on food security during the Covid-19 pandemic. During the MCO, local farmers faced with agricultural produce dumping due to the close of several support sectors such as retail, transportation, and food services. The agricultural supply chain was also affected due to a lack of agricultural inputs and a shortage of labor. This situation is worsened by the inadequacy of food storage facilities which has caused damage to agricultural produce. The demand for food among the community continued to increase during the MCO due to the panic-buying. This study also highlighted several suggestions toward improving the stability of food security in order for the country to withstand any crisis.

ABSTRACT

The present study analyzes the market access of the biggest fish market at Chattogram coastal region of Bangladesh affected by COVID-19. The food chain was reduced locally, regionally, and globally as supply chains were disturbed and international seafood exports were halted for a certain period. For data collection several qualitative data collection tools, such as individual interviews as well as secondary document analysis were employed. To realize the overarching aim of this research the whole market system was analyzed including the supplier, wholesaler, retailer, as well as the consumer of the domestic market in the Chattogram district. The result shows that the pandemic slowed the supply and demand in the domestic fish market, and as a consequence the price of fish was distinctly reduced in the whole market system. The result highlights that the most affected stages of the supply chains are the supply quantity, the interval of the supply, and the quantity of fish sales. Furthermore, the principally affected stages of the demand chains are consumer demand and alternation in the preference of the consumer. To overcome such situation, this study recommends governmental financial support to trades to ensure the smooth flow of the supply and demand and create an alternative market system for the consumer. The pandemic and the measures to address the pandemic have created significant new challenges for market access and controlling pricing in domestic markets. Regularly engage of the policymakers are thus the prerequisite to overcome the compensation of trades and ensure food security in this sector.

ABSTRACT

With the rapid growth of the elderly population of China in recent years, the service demands of older Chinese people continue to increase. The increasingly severe situation with respect to the elderly population is an important social problem that China will face for a long time into the future. It is urgent to solve the problem of how to scientifically carry out allocation planning of service resources for the aged and guide the effective supply of service resources. This paper analyzes the factors affecting service resources for the aged, divides China’s service resource supply and demand system into a supply subsystem, a demand subsystem, and a population and economy subsystem. Using system dynamics methods to analyze the causal relationship between variables and the state space method to build a mathematical model and perform simulation analysis, we research the the current situation of China’s service resources supply and demand balance for the aged. In addition, we put forward resource configuration optimization measures for the future allocation of service resources for the aged, providing a practical basis for future decision-making.

ABSTRACT

This study aims to develop a multi-dimensional night-time economy vitality index (NTEVI) to measure the vitality of night-time economic (NTE) activities in Zhejiang Province, China, covering its 11 cities and 90 counties. Comprising 44 supply and demand indicators of the NTE, the index was composed of an overall index and six major sub-indices that measured the vitality of six typical NTE subsectors, including catering, shopping, recreation, accommodation, touring, and fitness. The NTEVI was calculated using a unique multi-source dataset based on hourly online transaction data from a leading Chinese online-to-offline service platform, monthly night-time electricity consumption data, and official statistics from 2019 to 2020. Robustness and sensitivity analyses were conducted to ensure high credibility of the index results. The findings of this study suggested that the NTEVI was highly and significantly correlated with night light indices, economic indicators, and tourism demand measures. By identifying regional and temporal differences across several service sectors over time at the county, city, and provincial levels, the NTEVI serves as a powerful numerical and visual tool: it offers key information to guide policy formulation, resource allocation, and policy evaluation. In the context of COVID-19, the index analyses also reflect the NTE recovery process in Zhejiang Province. Our findings indicate that it is important for the Chinese government, regional authorities, and enterprises to encourage the NTE as a main driver of economic revitalization.

ABSTRACT

The economic crisis caused by the external shock in the form of the COVID-19 pandemic had the character of a systemic risk affecting all markets in the world. Due to high levels of economic integration, negative spillover effects were inevitable. Indirect effects particularly affected the agricultural sector with simultaneous shocks on the supply and demand side. The research includes an analysis of negative distortions of a macroeconomic nature in order to show in the most adequate way the vital importance of the agricultural sector at the level of the European Union (EU). Given the acute nature of the economic crisis, interventions at the EU level (and in countries) targeting exit strategies have a key role to play. The analysis of the implemented strategies in the EU in 2020 indicates that: (a) economic policymakers have minimized the gap in the implementation of measures, by applying generous and prompt programs aimed at the agricultural sector;(b) there is a need to move from urgent rescue programs to "no regrets" programs that can improve the resilience of the agricultural sector to future external shocks in the long run.

ABSTRACT

The fashion industry is adapting to the new situation caused by the COVID-19 pandemic by changing the structure of its supply chain, much like other industries that experience exogenous shocks. The pandemic affected conditions of apparel retailers: downstream among consumers and upstream among suppliers. It induced retailers to accelerate the adoption of technologies to make their supply chains more flexible and resilient. Before COVID-19, the apparel industry had gradually adopted virtual dressing room (VDR) technologies and crowd wisdom software, both of which reduce the risk associated with online purchases. Apparel retailers also altered the structure of their supply chains by outsourcing product turns via third-party logistics providers. This article analyzes how changes in market demand and supply conditions following the outbreak of COVID-19 accelerated the adoption of VDR technologies. The analysis is based on a conceptual micro-economic model of adopting technologies and changes in the supply chain. We support our theoretical findings with business cases. Understanding the nonlinear relationships among changes in demand, supply chains, and retail technology adoption triggered by exogenous shocks is essential for managers and affects the quality of service.

ABSTRACT

The COVID-19 epidemic has posed a grave threat to human life. The stay-at-home quarantine is an effective method of minimizing physical contact and the risk of COVID-19 transmission. However, the supply of living materials (such as meat, vegetables, grain, and oil) has become a great challenge as residents' activities have been restricted. In this paper, we present a spatial analysis framework for the supply of living materials during COVID-19 outbreak by coupling an infectious disease model with geographic information system (GIS). First, a virus spreading spatial simulation model is developed by combining cellular automata (CA) and Susceptible-Exposed-Infected-Recovered-Death (SEIRD) to estimate COVID-19's spreading under various scenarios. Second, the demand and supply of living materials in the impacted residents are calculated. Finally, the imbalance of the supply and demand of the living materials is assessed. We conduct experiments in Shenzhen. The experimental results show that localities with supply-demand mismatches are primarily concentrated in the southwest of Bao'an District, the southern of Longhua District, and Longgang District. Additionally, the spatial distribution of the mismatch level between supply and demand for living materials in Shenzhen exhibits a significant agglomeration effect, manifested as "low-low" and "high-high" agglomeration. The spatial agglomeration effect of material mismatch has increased with the spread of the epidemic. These results support the prevention and control of the COVID-19 spreading.

ABSTRACT

Food is the core of urban daily life and socio-economic activities but is rarely the focus of urban planning. The spatial layout of food retail outlets is important for optimizing the urban food system, improving land resource allocation, and encouraging healthy food consumption. Based on food retail POI data, this study employed kernel density estimation, road network centrality, spatial autocorrelation analysis, and locational entropy to analyze the spatial characteristics of supermarkets, produce markets, and small stores in an urban center in Beijing, and explored street coupling and supply-demand matching. The results indicated that within the study area: (1) supermarkets had an obvious “core-periphery” distribution, produce markets had a polycentric distribution, and small stores had a relatively uniform distribution;(2) road network centrality indices revealed a differentiated multi-core-edge distribution;(3) streets with high locational entropy values for supermarkets and produce markets were mostly concentrated in the central area, whereas the matching distribution of small stores was relatively balanced. From the perspective of urban planning, policy implications are proposed based on spatial and social equity, urban-rural differences, population structure and distribution status, and a resilient supply chain. The study findings have practical significance for guiding the development of urban food systems in a healthy, just, and sustainable direction, as well as rational urban land planning.

ABSTRACT

China’s livestock output has been growing, but domestic livestock products such as beef, mutton and pork have been unable to meet domestic consumers’ demands. The imbalance between supply and demand causes unstable livestock prices and affects profits on livestock. Therefore, the purpose of this paper is to provide the optimal breeding strategy for livestock farmers to maximize profits and adjust the balance between supply and demand. Firstly, when the price changes, livestock farmers will respond in two ways: by not adjusting the scale of livestock with the price or adjusting the scale with the price. Therefore, combining the model of price and the behavior of livestock farmers, two livestock breeding models were established. Secondly, we proposed four optimal breeding strategies based on the previously studied models and the main research method is Pontryagin’s Maximum Principle. Optimal breeding strategies are achieved by controlling the growth and output of livestock. Further, their existence was verified. Finally, we simulated two situations and found the most suitable strategy for both situations by comparing profits of four strategies. From that, we obtained several conclusions: The optimal strategy under constant prices is not always reasonable. The effect of price on livestock can promote a faster balance. To get more profits, the livestock farmers should adjust the farm’s productivity reasonably. It is necessary to calculate the optimal strategy results under different behaviors.
