PurposeThis study investigates the impact of agri-food supply chains (AFSCs) characteristics on the antecedents of horizontal logistics collaboration (HLC). Specifically, the study compares the relationship between collaboration activities and outcomes for companies in and outside AFSCs.Design/methodology/approachFirst, a survey was used to collect data from different industries. Second, confirmatory factor analysis and structural equation modeling were applied to compare the measurement and structural models from different industry categories.FindingsThe results support the premise that collaboration improves trust and commitment in the relationship, which in turn enhance satisfaction. The results also show the existence of a minor influence of AFSCs characteristics on HLC antecedents, in the form of an indirect impact of dedicated investments on commitment.Practical implicationsThe factors having a significant influence on the collaboration outcomes and their respective effects are generally similar across food and nonfood supply chains, providing opportunities for interdisciplinary and collaboration experiences.Originality/valueThis research contributes to the body of knowledge on interfirm collaboration by considering the specificities of HLC. It also highlights the importance of conducting contingency research on collaborative experiences, as firms from different industry contexts operate under distinct operational conditions.

The evaluation issues on the aggregate’s extraction on the ecosystem of bodies of water has been considered. The dredgers' impact of various capacities on bodies of water of different capacities have been compared, as well as on food supply change of bodies of water for benthos eater. The research findings have showed the dragger's impact of a higher capacity is bigger on a large body of water than this of a lower capacity on a small body of water. The impact manifests itself in decreasing the number and biomass of macrozoobenthos in the area used for the oil and lubricants extraction and the downstream flow. It has been found that the complete destruction of macrozoobenthos at the site of hydraulic engineering activities has not been detected either in small rivers or in large reservoirs.

Large vertebrates affect fire regimes in several ways: by consuming plant matter that would otherwise accumulate as fuel; by controlling and varying the density of vegetation; and by engineering the soil and litter layer. These processes can regulate the frequency, intensity and extent of fire. The evidence for these effects is strongest in environments with intermediate rainfall, warm temperatures and graminoid-dominated ground vegetation. Probably, extinction of Quaternary megafauna triggered increased biomass burning in many such environments. Recent and continuing declines of large vertebrates are likely to be significant contributors to changes in fire regimes and vegetation that are currently being experienced in many parts of the world. To date, rewilding projects that aim to restore large herbivores have paid little attention to the value of large animals in moderating fire regimes. Rewilding potentially offers a powerful tool for managing the risks of wildfire and its impacts on natural and human values. This article is part of the theme issue ‘Trophic rewilding: consequences for ecosystems under global change’.

The novel coronavirus disease 2019, or COVID-19, is a recent disease that has struck the entire world. This review is conducted to study the impacts of the COVID-19 pandemic to food safety as well as the food supply chain. The pandemic has caused various changes around the world as numerous countries and governments have implemented lockdowns and restrictions to help curb the rising cases due to COVID-19. However, these restrictions have impacted many aspects of everyday life, including the economic sectors such as the food industry. An overview of the current COVID-19 situation in Malaysia was discussed in this review along with its implication on food safety and food supply chain. This is followed by a discussion on the definition of food safety, the impact of the pandemic to food safety, as well as the steps to be taken to ensure food safety. Hygiene of food handlers, complete vaccination requirement, kitchen sanitation and strict standard operating procedures (SOPs) should be in place to ensure the safety of food products, either in food industries or small scale business. Additionally, the aspect of the food supply chain was also discussed, including the definition of the food supply chain and the impact of COVID-19 to the food supply chain. Travel restriction and lack of manpower had impacted the usual operation and production activities. Lack of customers and financial difficulties to sustain business operational costs had even resulted in business closure. As a conclusion, this article provides insight into crucial factors that need to be considered to effectively contain COVID-19 cases and highlights the precaution methods to be taken through continuous monitoring and implementation by Malaysian government.

Purpose The current complex halal food supply chain (SC) has caused food scandals, which have illustrated the weakness of multiple food quality standards and certification and audits in ensuring food safety. Drawn on the resource-based view (RBV) theory, the purpose of this study is to explore the impacts of SC integration (SCI) on halal food SC integrity and, consequently, food quality. Design/methodology/approach Empirical data were collected from 275 halal-certified food companies in Malaysia and analysed using structural equation modelling – SmartPLS3.0. Findings The results confirmed that SCI, including internal, supplier and customer integrations, has significant effects on the dimensions of the halal food SC integrity which, in turn, lead to halal food safety and quality. Practical implications The importance of SCI in halal food SC is highlighted in this study. The impact of SCI is contexted in halal food SC integrity and food quality. Therefore, it provides a clear understanding to managers of SC applicability in the halal food industry. Originality/value Based on the RBV theory, this study contributes to the limited body of research of the relationships among SCI from the context of the halal industry with a specific focus on food supply chain integrity and food quality.

Global food production needs to increase by approximately 70% by 2050 to ensure food security and feed the global population which is expected to reach 9.6 billion by 2050. To achieve these objectives in a sustainable manner, there is a need for modernisation and intensification of agricultural practices. There is also an increasing demand for proving sustainability within supply chains with research showing a direct correlation between transparency and consumer trust in agri-food products. This chapter starts out by detailing the impact and need for a globalised food system. It then progresses to discuss existing applications of Internet of Things (IoT) systems and the potential of future IoT systems in helping achieve these targets. The chapter also briefly touches upon the potential for combining Blockchain Technology and IoT systems in helping improve transparency and accountability within agri-food supply chains.
