Purpose -The purpose of this paper is to give an up-to-date and structured insight into the most recent literature on humanitarian logistics, and suggest trends for future research based on the gaps identified through structured content analysis. Design/methodology/approach -The authors use a quantitative and qualitative content analysis process to analyse the characteristics of the existing literature, identifying the most studied topics in six structural dimensions, and presenting gaps and recommendations for further research. Findings -It was found that existing humanitarian logistics research shows too little interest in continuous humanitarian aid operations, in slow onset disasters and man-made catastrophes. While several papers address different phases of disasters, very few focus particularly on the reconstruction following a disaster. Empirical research is underrepresented in the existing literature as well.Research limitations/implications -While five of the authors' structural dimensions are inspired by previous reviews, the sixth dimension (situational factors) is derived from a theoretical framework which the authors developed and which has never been tested before. The validity of the study could therefore be increased by testing this framework. Originality/value -The authors analyse the broadest set of papers (174) ever covered in previous literature reviews on humanitarian logistics. A quantitative analysis of the papers was conducted in order to analyse the situational factors which have mostly been studied so far in literature. This paper is also the first in humanitarian logistics to use content analysis as the main methodology to analyse literature in a structured way, which is of particular value to the academic community as well as practitioners.

The lack of transparency and traceability in food supply chains (FSCs) is raising concerns among consumers and stakeholders about food information credibility, food quality, and safety. Insufficient records, a lack of digitalization and standardization of processes, and information exchange are some of the most critical challenges, which can be tackled with disruptive technologies, such as the Internet of Things (IoT), blockchain, and distributed ledger technologies (DLTs). Studies provide evidence that novel technological and sustainable practices in FSCs are necessary. This paper aims to describe current practical applications of DLTs and IoT in FSCs, investigating the challenges of implementation, and potentials for future research directions, thus contributing to achievement of the United Nations’ Sustainable Development Goals (SDGs). Within a systematic literature review, the content of 69 academic publications was analyzed, describing aspects of implementation and measures to address the challenges of scalability, security, and privacy of DLT, and IoT solutions. The challenges of high costs, standardization, regulation, interoperability, and energy consumption of DLT solutions were also classified as highly relevant, but were not widely addressed in literature. The application of DLTs in FSCs can potentially contribute to 6 strategic SDGs, providing synergies and possibilities for more sustainable, traceable, and transparent FSCs.
