The Impact

In Bangladesh, the COVID-19 pandemic is likely to have substantial effects on the livelihood of people, but smallholder vegetables growers will be even more affected because of the perishability nature of the product. The first case of COVID-19 was confirmed in Bangladesh on 8th March, 2020 and consequently the country went into lockdown on 26 March, 2020. This study has made a survey of vegetables farmers through a mobile phone to understand the impact of COVID-19 on vegetables supply chain, gross margin and the future production plan of the growers. In Bangladesh, the lockdown has disrupted the food supply chain and increases the likelihood of food insecurity. Lockdown has impeded vegetable farmers’ access to markets, thus limiting their productive and sales capacities. The price of yield has dropped by more than half resulting in huge loss for vegetable growers. The loss incurred by the farmers for producing Brinjal, Cucumber, Pointed gourd, Yardlong beans and Bottle gourd are BDT 4900, BDT 10900, BDT 57400, BDT 52500 and BDT 18500 per acre respectively as a result of COVID-19. The decreased income increases farmers’ likelihood of vulnerability and food insecurity and poses a challenge to continued produce. ‘Cash support’ is more important than ‘food support’ in order to keep vegetable farmers in farming, to ensure a ready supply of necessary low-cost resources, and to help fight against the upcoming food shortage.

Abstract The COVID-19 and partial lockdown has brought significant effects on the entire economy, especially on food security and job losses. This study was carried out in Asokwa Municipal with the objective of examining the impact of COVID-19 disease and its related lockdown on food and nutrition security and job losses. The study site form part of the cities in Ghana to experience the partial lockdown, hence it qualifies for the selection. Both primary and secondary data were used. By means of purposive sampling technique, fifty respondents were selected as sample size. The study employed a qualitative approach with a descriptive and narrative posture to the presentation, discussion and analysis of data. Open-ended questionnaire and a checklist were used for data collection through semi-structured interviews. The results revealed that, food and nutrition insecurity, job loss and income reductions are still very common, affecting participants livelihood. Disproportionally affected are households whose income comes from farming, transporters, informal labour, as well as marketers.It was concluded that food insecurity is not outside the impact of COVID-19 and its associated partial lockdown. Food and nutrition security are the global concern at present circumstances. The supply chain has been hit hardest by COVID-19, which causes food insecurity of most vulnerable segment of population which put them at risk. And also, most of the migrant, informal, seasonal farm workers were losing their jobs which may affect their demand for food. Therefore, the government should step-up the measures to control the pandemic without disturbing the food supply chain. The development and use of online marketing strategies where people can make orders of various produce and booked for purchases and or deliveries during a stated time range should be promoted.

The Impact

Currently, for analyzing harmonic impacts on voltage at a point of interest, due to multiple nonlinear loads, the literature recommends carrying out simultaneous and synchronized measurement campaigns in all suspicious points with the use of high cost energy quality analyzers that are usually not available at the customers’ facilities and very often also not at the electric utilities. To overcome this drawback this paper proposes a method of assessing the harmonic impact due to multiple nonlinear loads on the total voltage harmonic distortion using only the load current true RMS values which are already available in all customers’ installations. The proposed methodology is based on Regression Tree technique using the Permutation Importance indicator which is validated in two case studies using two different electrical systems. The first case study is to ratify the use of Permutation Importance to measure the impact factor of each nonlinear load in a controlled scenario, the IEEE-13 bus test system, using ATP simulation (Alternative Transient Program). The second is to apply the methodology to a real system, an Advanced Measurement Infrastructure System (AMI) implanted on a campus of a Brazilian University, using low cost meters with only true RMS current measurements. The results achieved demonstrated the feasibility of applying the proposed methodology in real electric systems without the need for additional investments in high-cost energy quality analyzers.

Household Dietary Diversity

Abstract Objectives We conducted a non-randomized evaluation of a nutrition education program delivered by Soins de Santé Primaire in rural Senegal to identify the impact of participation on household dietary diversity scores (HDDS). We also sought to understand participant's perceptions of program strengths and weaknesses. Women participated in a single education session that emphasized hygiene, selecting from a variety of food groups, risk awareness of diet-related non-communicable diseases, and a recipe demonstration of a locally-sourced, balanced meal. We hypothesized that program participation would be associated with increased HDDS. Methods We surveyed 20 female program participants sampled from two communities and compared their responses with 20 women sampled from two non-intervention communities (n = 40). Surveys collected 24-hour dietary recall to calculate a dietary diversity score using the 12-point HDDS scale. The mean difference in HDDS was evaluated between post-program and comparison groups using linear regression. Models controlled for household size, employment, education, marital status, and the Food Insecurity Experience Scale. We conducted key informant interviews with post-program participants (n = 19) to understand message recall, reported behavior change, and feedback for future sessions. Results Women in intervention households reported higher HDDS than comparison households [Mean (SE) = 9.0 (0.39) vs. 7.65 (0.24), P = .003]. In the adjusted model, program participation was positively associated with HDDS (β = 1.16, P = .041). Household food insecurity was associated with lower HDDS (β = −0.52, P = .024). Program participants recalled the importance of reducing bouillon cube usage and eating from each food group. Participants reported changes in food preparation and hygiene routines, such as adding more beans or vegetables and changing dirty dishwater often. The key improvement suggestion was to increase session frequency and expand education on hygiene and sanitation. Conclusions Low intensity nutrition education programs that include meal demonstrations may be a low-cost, effective method for improving dietary diversity among a population with moderate food insecurity in rural Senegal.

ABSTRACT The possibility to vary the energy matrix, thus reducing the dependency on fossil fuels, has amplified the acceptance of biomass as an alternative fuel. Despite being a cheap and renewable option and the fact that Brazil is a major producer of waste from agriculture and forestry activities, the use of these materials has barriers due to its low density and low energetic efficiency, which can raise the costs of its utilization. Biomass densification has drawn attention due to its advantage in comparison to in natura biomass due to its better physical and combustion characteristics. The objective of this paper is to evaluate the impact of biomass densification in distribution and transport costs. To reach this objective, a mathematical model was used to represent decisions at a supply chain that coordinates the purchase and sale of forestry and wood waste. The model can evaluate the options to deliver biomass through the supply chain combining demand meeting and low cost. Results point to the possibility of an economy of 60% in transport cost and a reduction of 63% in the required quantity of trucks when densified waste is used. However, costs related to the densifying process lead to an increase of total supply costs of at least 37,8% in comparison to in natura waste. Summing up, the viability of biomass briquettes industry requires a cheaper densification process.

This research study was conducted with the purpose of understanding the impact of COVID-19 on the logistics segment and the associated disruptions in the food supply chain. In the current times, the entire world is challenged by a disease called coronavirus or popularly known as Covid-19. In December 2019, Wuhan in China reported the first case ever. COVID-19 has heavily affected the supply chain networks, logistics in particular. Markets and firms are connected by Logistics companies through the provision of different services, including multimodal transportation, freight forwarding, warehouse management, and inventory management. A diverse pool of logistics players across the world have been impacted owing to the current state of the pandemic. This paper analyzes the disruptions in the movement and delivery of essential food items and how resilient a supply chain should be during such periods of crisis. An experiment was carried out to understand the factors affecting the food essentials delivery to the local kirana stores. For this, a survey of 200 respondents (kirana shop owners) was conducted with the help of a 14-item questionnaire. Factor analysis was the tool used to analyze the results and the software used was SPSS. The outcome of the analysis showed that 5 factors were extracted which tried to explain the 14 variables used in the survey which were afflicted due to the coronavirus pandemic.

The SADC region has seen both man-made and natural disasters killing over 90 thousand people and affecting millions in the past 33 years. Most of these deaths were as a result of lack of infrastructure and preparedness. Looking at the challenges for providing relief to victims/evacuees throughout the entire disaster and post-disaster periods in the region, the emphasis of this thesis is on last mile transportation of resources, victims, emergency supplies, aiming to optimize the effectiveness (quick­I response) and efficiency (low-cost) of logistics activities including humanitarian supply chain. A survey was used for data collection. Statistical analysis helped determine the impact of disaster relief chains and lead to the development of a mathematical model that shall equip the region with mechanisms for response and recovery operations. An EXCEL optimization tool was used to find the optimal way of transporting relief in the region in case of a disaster.

Every industry, organization or individual needs to be minimize their expenditure, time and fatigue and maximize their profit in supply chain. These goals can be achieved through automation by using Radio Frequency Identification (RFID) and Zigbee wireless communication technologies, which is easily available in the market. Basically RFID technology is used for automatically tracking, locating or identifying the entities. It can easily integrate with low cost low power consumption Xbee (Zigbee) device, which is used to increase the communication range by large number of node deployment. RFID-Xbee network integrates with Laboratory Virtual Instrument Engineering Workbench (LabVIEW) Graphical User Interface (GUI), which gives real time information of supply chain at single control panel. The integrated communication model proves the near field inductive coupling and can be used in supermarket for item pricing, office automation, security system, and car parking. This system confirms the concept of real-time locating system (RTLS) in an indoor environment. The impact of RFID and Xbee network communication model enhance the read range of RFID reader, so that out of range items can be tracked easily without additional RFID readers. The benefit of this system is to maximize profit, reduce human intervention and minimize waste.

PurposeThe current study addresses how blockchain can deal with the challenges that the midstream liquefied natural gas (LNG) supply chain poses combined from a management standpoint. Such challenges are: the volume of transactions, communication hurdles and the lack of contemporary management tools. The paper proposes a comprehensive framework to assess the impact of blockchain implementation in the midstream LNG supply chain in order to tackle those barriers.Design/methodology/approachThe basis of the research is the business process modelling (BPM), through which entities, roles, tasks, resources and transactions can be modelled and simulated. The modelling of the midstream LNG supply chain, via BPM, is based on guidelines of the Society of International Gas Tanker and Terminal Operators (SIGGTO) and common industry business models. A quantitative analysis is employed to support the motivation and the potential impact of blockchain implementation. The methodology is used to identify (1) inefficiencies related to large volume of transactions between stakeholders and (2) critical areas of an LNG shipping company, where blockchain can be implemented.FindingsProcess repeatability, numerous shared documentation forms, excessive paperwork and communication imbroglios are mapped from the modelling section. Up to 327 processes are repeated during a typical vessel voyage, and up to 122 shared documentation forms are exchanged. Excessive paperwork and communication imbroglios are tracked through, which correspond to 25 severe errors as detected. By implementing the methodology, stakeholders can quantify the possible impact of blockchain on the operational performance of each stakeholder's operations separately and the supply chain as a whole in terms of real-time monitoring, transparency and paperwork reduction, time and cost savings.Research limitations/implicationsThe research has certain limitations deriving from its conceptual nature. The business processes' modelling is based on standard procedures described in the guidelines by SIGGTO and may need further adjustment for specific use cases. A structured case study has not been realisable as corporate data for an LNG shipping company regarding processes and other commercial sensitive information are required.Practical implicationsPotential practitioners may exploit the proposed framework as a low cost and seamless tool to evaluate how blockchain could disrupt their operations. Thus, the blockchain implementation's improvements or weaknesses can be pinpointed, and enabling the interested stakeholder of the LNG supply chain with specific feedback, it can guide them towards informed decisions on their operations.Originality/valueThe research has a novel approach as it combines the creation of practical management framework, with a comprehensive visualization of the midstream LNG supply chain. Thus, the reader can identify in which parts of the midstream LNG supply chain can blockchain be implemented, and what impact it could have in terms of supply chain operations.
