Integration of digitalization and automation with logistics systems promotes effective and efficient flow of goods, information, and services, contributing to economic development. The level of implementation of digitalization and automation in low-income countries is still low, however. The aim of this study is to establish which digitalized logistics practices could best be adopted by firms in low-income countries. A systematic literature review was used to identify state-of-the-art digitalization and automation technologies in logistics chains. Criteria for adopting digitalized logistics practices were also identified in the literature review. An expert survey was conducted to identify criteria weights using analytical hierarchy process (AHP). Economic benefit, infrastructure, and affordability were the criteria that were given the highest weights by the experts. Case studies that applied state-of-the-art technologies such as internet of things (IoT), radio frequency identification (RFID), blockchain, big data analytics (BDA), and sensors mainly for traceability, production operation, and warehouse and inventory management were considered as recommended practices. Identification of suitable practices considering the local conditions in low-income countries could help logistics professionals and policymakers adopt enabling technologies in logistics chains.

Urban logistics policies have become instrumental in achieving sustainable transport systems. Developing and emerging countries still lag far behind in the implementation of such policies when compared with developed countries. This exposure gap provides an opportunity for policy transfer, but this is a complex process requiring knowledge of many contextual factors and involving multiple steps. A good understanding of those contextual factors of measures by cities may be critical for a successful transfer. Our study aimed to identify the different contexts of urban logistics measures or policies worldwide and to assess their significance for policy transferability. In this study, urban logistics measures discussed in the literature were retrieved with a systematic literature review method and then the contexts were recorded, distinguishing between economic development levels and geographical regions. The analysis revealed that the economic level and geographical location of cities both have a strong association with the type of measure implemented. Barriers and drivers were identified by assessing policy transfer between developed and developing countries. Institutional and physical barriers appeared to be highly pertinent for a range of measures, while drivers or facilitators were identified from specific problems in developing countries and the respective measures in developed countries. Thus, the analysis of contextual factors can provide a first response to the key challenges and opportunities of sustainable urban logistics policies transfer to developing countries.

Industrial wastes have been increasingly discharged into water and soil, and causing environmental pollution in Ethiopia. This study examined the occurrence of heavy metal in water, soil, and plants in fields irrigated with industrial wastewater in Sabata town, Ethiopia. The composite samples of soil, water, and vegetables were collected accordingly to determine the concentration of heavy metals (Cu, Pb, Zn, Mn, and Ni) in each system during dry and wet seasons. The concentration of heavy metal was assayed using atomic absorption spectrophotometry. The data were statistically analyzed using one-way ANOVA. The heavy metal concentration was decreased in the order of Pb > Mn > Ni > Cu > Zn, Mn > Ni > Pb > Cu > Zn, and Ni > Pb > Mn > Cu > Zn in the water, soil, and vegetables in the area respectively. The variation of levels of heavy metal in the water, soil, and vegetable might be because of the effect of heavy metal speciation and valence, industry types, vegetable types and tissues, and soil. The bioconcentration factor of heavy metals was higher than that one for copper, signifying the increased probability of health risk for those who are consuming vegetables grown in the area. Thus, the government should take this into account and devise mitigation strategies through the implementation of heavy metal removal systems from contaminated water and soil, waste management strategies of recycling, centralized or decentralized treatment plant, changing of industrial residual into biogas production, and awareness creation for the society.

Biomass residues from permanent crops might be an alternative fuel for energy generation in a local market with limited transport distances. Moreover, as activities related to CO2 reduction are of special attention in the European Union (EU), sustainable use of resources plays an important role in climate change mitigation. In this paper, a life-cycle assessment (LCA) of the integrated value chain from peach pruning residues for electricity generation is presented and compared with the common practice including the mulching process of the pruned biomass in an orchard. It was shown that biomass harvesting, chipping and its delivery to a power plant—the Pruning-to-Energy (PtE) scenario—is feasible from an environmental point of view. The total global warming potential (GWP) of this value chain was 200 kg CO2 eq.·ha−1 (or 27 kg CO2 eq.·GJ−1). In turn, the mulching and leaving of the pruned biomass in an orchard—the pruning-to-soil (PtS) scenario—is characterized by a CO2 equivalent of 2360 kg·ha−1. Other impact categories showed a lower environmental impact for the PtE scenario as well. When considering the Spanish electricity-mix instead of coal-based electricity, the PtS scenario score better in most impact categories, but the GWP for the PtE scenario remains lower.

Recently, the concept of supply chain management has been applied in the food chains with the idea of transforming agribusiness through networking and trustful partnership in the food chains. In this regard, it is important to consider the empirical knowledge of the interface among the variables of factors in the supply chain governance structure choices, the chain actors’ choice of governance models, and the effects of these on the supply chain performances. The aim of this study was to empirically verify the relationships between factors existing in the business scenarios, the chain actors’ governance structure choice, and supply chain performances of dairy chains in Ethiopia. The chains were assessed using the survey data that were collected from 215 chain actors and analyzed using structural equation modelling and IBM SPSS and IBM AMOS of version 24 software. The data collected were tested for the Cronbach’s alpha reliability test for the internal consistency and using the different model goodness of fit measure tests. The results showed that the transaction cost, trust, and uncertainty significantly (P

The paper presents a report on the performance evaluation of a newly developed smart logistics system (SLS). Field tests were conducted in Spain, Germany, and Sweden. The evaluation focused on the performance of a smart box tool (used to capture information during biomass transport) and a web-based information platform (used to monitor the flow of agricultural pruning from farms to end users and associated information flow). The tests were performed following a product usability testing approach, considering both qualitative and quantitative parameters. The detailed performance evaluation included the following: systematic analysis of 41 recordable parameters (stored in a spreadsheet database), analysis of feedback and problems encountered during the tests, and overall quality analysis applying the product quality model adapted from ISO/IEC FDIS 9126-1 standard. The data recording and storage and the capability to support product traceability and supply chain management were found to be very satisfactory, while assembly of smart box components (mainly the associated cables), data transferring intervals, and manageability could be improved. From the data retrieved during test activities, in more than 95% of the parameters within 41 columns, the expected values were displayed correctly. Some errors were observed, which might have been caused mainly by barriers that could hinder proper data recording and transfer from the smart box to the central database. These problems can be counteracted and the performance of the SLS can be improved so that it can be upgraded to be a marketable tool that can promote sustainable biomass-to-energy value chains.

The utilization of agricultural prunings as renewable energy sources requires effective and efficient logistics systems. The objective of this paper was to map out logistics activities along the agricultural pruning-to-energy (PtE) value chains. It describes the logistics performances based on the existing and potential pruning biomass supply chains focusing on prunings from fruit tree, vineyards, olive groove, and up-rooted tree branches. A logistics audit analysis approach has been used for detailed assessment of logistics performances. The analysis was based mainly on primary data gathered using a structured data survey format targeting the existing and potential PtE initiatives in Spain, Germany, Denmark, France, and Poland. The analysis considered the major stages of the chain, such as pruning, harvesting, processing (e.g., baling and chipping), storage, transport, and the linkage between the different stages. The paper identified the constraints along the logistics chain and recommended appropriate interventions to promote the marketing of agricultural pruning focusing on the supply of quality bales and chips for renewable energy production, and to increase the sustainability of renewable energy generation from PtE initiatives. The study has indicated that there are economic, social, and environmental benefits of PtE initiatives, as well as opportunities to increase the implementation and sustainability of the system.

Agricultural pruning biomass is one of the important resources in Europe for generating renewable energy. However, utilization of the agricultural residues requires development of efficient and effective logistics systems. The objective of this study was to develop smart logistics system (SLS) appropriate for the management of the pruning biomass supply chain. The paper describes the users’ requirement of SLS, defines the technical and functional requirements and specifications for the development of SLS, and determines relevant information/data to be documented and managed by the SLS. This SLS has four major components: (a) Smart box, a sensor unit that enables measurement of data such as relative humidity, temperature, geographic positions; (b) On-board control unit, a unit that performs route planning and monitors the recordings by the smart box; (c) Information platform, a centralized platform for data storing and sharing, and management of pruning supply chain and traceability; and (d) Central control unit, an interface linking the Information platform and On-board control unit that serves as a point of administration for the whole pruning biomass supply chain from harvesting to end user. The SLS enables the improvement of performance of pruning biomass supply chain management and product traceability leading to a reduction of product loss, increased coordination of resources utilisation and quality of solid biofuel supply, increased pruning marketing opportunity, and reduction of logistics cost. This SLS was designed for pruning biomass, but could also be adapted for any type of biomass-to-energy initiatives.

Consumers’ demand for locally produced and organic foods has increased in Sweden. This paper presents the results obtained from the analysis of data acquired from 100 consumers in Sweden who participated in an online survey during March to June 2016. The objective was to identify consumers’ demand in relation to organic food and sustainable food production, and to understand how the consumers evaluate food quality and make buying decisions. Qualitative descriptions, descriptive statistics and Pearson’s Chi-square test (with alpha value of p < 0.05 as level of significance), and Pearson’s correlation coefficient were used for analysis. About 72% of participants have the perception that organic food production method is more sustainable than conventional methods. Female consumers have more positive attitudes than men towards organic food. However, age difference, household size and income level do not significantly influence the consumers’ perception of sustainable food production concepts. Regionality, sustainable methods of production and organic production are the most important parameters to characterize the food as high quality and make buying decisions. On the other hand, product uniformity, appearance, and price were found to be relatively less important parameters. Food buying decisions and food quality were found to be highly related with Pearson’s correlation coefficient of r = 0.99.

To determine the environmental impact, the assessment of the Euro-Pruning project strategy has been carried out in accordance with the checking and scooping list related to Directive 97/11/EC. Additionally, some suggestions and recommendations to prevent/minimize the hazard of accidents or negative interaction on surrounding have been elaborated (according to the suggested procedure in ISO 14001 methodology: risk definition and prevention action proposal). As a consequence, the results of the inspection during the demo tests taking place in different orchards/plantations regarding the performance of the machineries operation, farmers’ habits and pruning residues harvesting procedures have been presented, in order to diagnose and determine possible risks that may occur and influence negatively the local environment. Similar activities have been carried out during the storage tests and transportation processes.

Biomass production and supply for renewable energy generation should be managed well and carried out in a sustainable manner. An effective traceability system (TS) is required to provide sufficient information and assure the quality of the biomass. The objective of this study is to define and develop a TS to assure the pruning biomass quality for the production of solid biofuels and to provide guarantee to the final user that the biomass is in good condition according to recommended quality criteria. It is designed for an agricultural pruning supply chain in which farmers, biomass traders, transporters, and end users are major actors. It is based on the biofuel quality requirements required by final users and other standards such as the new European standards EN 14961-1, EN15234:1-2011, and EN14961-1:2010, which describe solid fuel quality parameters. Traceable quality parameters include origin and source of product, traded form, bale dimension, chips size distribution, moisture content, ash content, and density of biomass. In this TS, a unique product label is introduced and integrated into a smart logistics system (SLS). The TS uses information captured at different stages of the product supply chain. It enables the management of the whole pruning biomass supply chain with the support of a centralized web-based information platform, an integral part of the SLS.

Post-harvest food loss is a global problem but it is more critical in the food-insecure countries. Food waste occurs at different levels in the food supply chain from production through post-harvest handling to consumption. The presented paper aims at an assessment of post-harvest food loss of warqe foods along the supply chain and identified hot spots of the losses in the chain. Warqe (Ensete ventricosum (Welw) Cheesman) is banana like plant and it used as a food and non-food applications. Kocho and bulla are two main food products of the warqe plant. A total of 522 responders were randomly selected across the supply chain started from the two major warqe growing areas. Kocho and bulla reach final consumers through various channels. About 45.3% of kocho and 45.6% of bulla were lost from the total marketed product along the supply chain. The highest kocho (24.0%) and bulla (28.8%) losses were observed at retailer and processor levels, respectively. Practicing poor processing method, using perishable packaging material, poor transportation and inappropriate storage and market conditions were the main reasons for the losses. It is, therefore, important to work on value addition in warqe foods, improve processing storage and packaging technologies to reduce post-harvest losses. Key words: Bulla, Ethiopia, Ensete ventricosum, kocho, post-harvest loss.

This study was made with the purposes of characterizing milk supply and marketing chains, post-production losses of milk, and evaluating the potential of supply chain management approach to reduce milk losses in Ethiopia. Primary data were collected by semi-structured survey questionnaire and interview of key informants. The collected data were analyzed using SPSS and Microsoft Excel sheets. Mapping, characterizations, and descriptive statistics were used to analyze the collected data. Both quantitative and qualitative-narrative methods were used in analysis. The finding revealed that farmers, cooperatives/unions, traders, and catering institutions were the major chain actors in milk chain in the study area. With 73% of milk sold by farmers passing through cooperatives/unions to the next chain actors, cooperatives/unions were the focal firms in this supply chain. Production was characterized by smallholders with few numbers of cows and low productivity of milk per cow per day. Cow breed and lack of access to credit were identified as critical resource and the most constraint that hinder production improvement. Marketing relationships among the chain actors were characterized as lacking long-term market orientation and were mostly on the spot and transaction based. The assessment on the enabling environment indicated further need of support from governmental and non-governmental stakeholders to build the capacity of chain actors, particularly the farmers. The study indicated existence of significant amount of milk losses in the milk chain. With 39% of the total losses happening at cooperatives/ union stage, cooperatives/unions were identified as loss hotspot point in the chain. Poor milk handling practice at the collection points, lack of immediate acceptors, milk carrying tools used, means of transport used, and ineffective communication with other partner in the chain were identified in order of severity as important problems causing milk losses in the study area. Based on the study results and review of others’ work in similar contexts, this study argued for SCM to be part of solution in improving this dairy chain. The study showed cases where effectively implemented SCM approach converted dairy chains from chains characterized by dismantled, high conflicts of interests among the chain actors, and high losses of food in the chain to chains with mutual interest trying to maximize the profit to the whole chain actors. Integrated and collective actions by all chain actors aiming at reducing costs, improving quality, and minimizing food losses in the chain were central to these efforts. Therefore, SCM approach needs to be part of the solution in increasing profitability and reducing milk losses in Ethiopia in general and in the study area in particular. However, the needs for detailed further study, some of which are recommended by this study, are worthwhile.

Freight transport system that minimizes costs, increase conveniences, and environmentally safe has become the agenda worldwide since long before. This study was made with the main objective of assessing intermodal termed as “multimodal” freight transport service in Ethiopia. Data was collected by using structured questionnaire from randomly selected customers and multimodal freight transport section employees of Ethiopian Shipping and Logistics Service Enterprise. The study was made in two stages using customers: first, they were asked to evaluate their satisfaction with the multimodal freight transport system; second, to evaluate their comparative satisfaction with the segmented/“uni-modal” freight transport system against five major freight transport performance indicators. Customers were also asked to identify and rank top ten problems of freight transport logistics in Ethiopia. Data were analyzed using SPSS and excel sheets with descriptive statistics and the results were depicted using charts and tables. The study indicated that majority of customers were either dissatisfied or very dissatisfied with many of the performance indicators. The employees evaluated their organization as well performing relatively on more performance indicators. Both customers and employees evaluated the documentation performances as satisfying but cost and convenience as dissatisfying performances. Customers identified repetitive custom checking and waste of time in custom inspections process as the most severe problem in freight transport logistics in Ethiopia. The implementation of intermodal freight transport system to bring better change in import-export freight transport logistics of Ethiopia was in bitter challenge for customers due to a number of problems, except documentation performance that showed betterment.

The aim of the study was to investigate the effects of transport time up to 12 h on welfare of bulls and cows. Cattle transport vehicle was used for the experiment. Sensors to measure temperature, relative humidity and video camera to monitor behaviour were mounted in observation pen. Eighteen measurements were performed during summer and winter for 4, 8, and 12 h transport time with three replications. To determine cortisol, glucose, lactate, and creatine kinase concentrations, blood samples were collected before and after transport from 80 bulls, 82 cows and 20 control animals. Cortisol concentration was generally inversely proportional to transport time (P < 0.001). Glucose concentration for cows was the highest at 12 h and the lowest at 8 h and for bulls it increased with transport time (P < 0.002). Lactate level generally correlated with transport time (P < 0.001), but for bulls the highest and the lowest were at 8 and 4 h in winter. Creatine kinase concentration positively correlated with transport time for bulls and cows but at different rates. Loss of balance and swaying strongly correlated with transport time (P < 0.002). Based on behaviour, stress hormones and pH values, an increase from 4 to 8 h had a higher effect than from 8 to 12 h transport time on welfare and subsequent meat quality.

This study was conducted at the Kumasi Abattoir Company Limited (K.A.C.L) in Ghana to assess the effect of pre-slaughter handling on welfare and meat quality of cattle. Behaviour measurements were done on 200 cattle pre-slaughter and the methods by which the cattle were handled were recorded to evaluate the effect of pre-slaughter handling on their welfare. Ultimate pH24 and percent cooking loss were measured on 50 poorly-handled cattle pre-slaughter. The cattle were poorly-handled because they were beaten and, whipped. Based on pH24, meat quality was assessed as normal (pH from 5.5–5.8), moderate dark, firm and dry (DFD) (5.8 ≤ pH ≤ 6.2), and DFD (pH from 6.2–6.7). Five hundred carcasses were visually observed for bruising in them and the number of non-ambulatory cattle slaughtered in a week was recorded. The relationship between pH24 value and cooking loss in meat from the 50 poorly-handled cattle was investigated. Behaviours exhibited by poorly-handled cattle pre-slaughter included raising of their tail, kicking, lying down and refusing to move, jumping, vocalising, panting, and charging at handlers. Also lashes/whips, pulling of animals’ tails, stamping on their tails, and hitting them with sticks, stones and ropes were among the prominent methods by which the cattle were handled. Mean pH24 and mean percent cooking loss were significant (p < 0.05) at 6.22 ± 0.10 and 22.51 ± 3.25, respectively, for poorly-handled cattle. There was a strong negative correlation between pH24 and percent cooking loss in poorly-handled cattle (r = −0.77). Out of the 500 carcasses assessed for bruising, 18% had no bruises, 60% had slight bruises while 22% had severe bruises. Ninety (90) non-ambulatory cattle were slaughtered within seven (7) days, representing 7.1% of the total number of cattle slaughtered within that period. The results indicated that handling of cattle pre-slaughter have effects on their meat quality and welfare. Eighty-two percent of the bruised carcass and 7.1% of non-ambulatory animals indicated poor meat quality. Meat quality assessment indicated that most of the meat had dark, firm and dry (DFD) tendency. The water holding capacity of the meat sampled in this study (by means of cooking loss) indicated that the meat quality was compromised.
