This paper systematically evaluates the existing literature of innovations in freight transport, including all modes, to uncover the key research themes and methodologies employed by researchers to study innovations and their implications in this industry. It analyses the role of transport and the impact of innovations during crises, such as COVID-19.

Qualitative and quantitative analysis of the innovations in freight transport unravels the pre-requisites of such endeavours in achieving a resilient and sustainable transport network that effectively and efficiently operates during a crisis. The authors performed keyword co-occurrence network (KCON) analysis and research focus parallelship network (RFPN) analysis using BibExcel and Gephi to determine the major resulting research streams in freight transport.

The RFPN identified five emerging themes: transport operations, technological innovation, transport economics, transport policy and resilience and disaster management. Optimisation and simulation techniques, and more recently, artificial intelligence and machine learning (ML) approaches, have been used to model and solve freight transport problems. Automation innovations have also penetrated freight and supply chains. Information and communication technology (ICT)-based innovations have also been found to be effective in building resilient supply chains.

Given the growth of e-commerce during COVID-19 and the resulting logistics demand, along with the need for transporting food and medical emergency products, the role of automation, optimisation, monitoring systems and risk management in the transport industry has become more salient. Transport companies need to improve their operational efficiency using innovative technologies and data science for informed decision-making.

This paper advises researchers and practitioners involved in freight transport and innovation about main directions and gaps in the field through an integrated approach for evaluating research undertaken in the area. This paper also highlights the role of crisis, e.g. COVID-19, and its impacts on freight transport. Major contributions of this paper are as follows: (1) a qualitative and quantitative, systematic and effective assessment of the literature on freight transport through a network analysis of keywords supplemented by a review of the text of 148 papers; (2) unravelling major research areas; (3) identifying innovations in freight transport and their classification as technological and non-technological and (4) investigating the impact of crises and disruptions in freight transport.

This paper aims to explore the evolution of the law for combating economic crimes including money laundering in Tanzania and explore the current developments in the anti-money laundering (AML) law and the ongoing fight against these crimes in Tanzania.

A desk-based review of documents on money laundering and its control in Tanzania was conducted. The paper presents qualitative data from the documentary sources. It applies the doctrinal legal research approach to examine, analyze and describe the AML law applicable in Tanzania. The paper uses the “law-in-context” research approach to explore some non-law aspects of money laundering in Tanzania and interrogate how the law addresses non-law dimensions of money laundering. Policy documents and media reports were analyzed. The thematic data analysis technique was applied, which involved identifying, describing and reporting issues according to the themes emerging from the data.

The AML law in Tanzania emerged from the law that was originally enacted to curb economic crimes. The law has evolved for some decades. Its evolution has been driven by domestic factors and foreign drivers which are political, economic and social in nature. The role of the AML law has been changing. Initially, the law was a tool for curbing economic crimes. Recently, the law has acquired a new role, namely, to facilitate the recovery of illicit funds and non-financial assets from offenders and enable the authorities in Tanzania to use those economic resources for developmental purposes.

The paper underscores the need for the Government of Tanzania to re-consider the broader implications involved in its current efforts to tackle economic crimes and money laundering. The balance between the implementation of the measures to combat money laundering and economic crimes in Tanzania and the importance of protecting rights of persons indicted with those offences should be struck. The AML law should be applied in such a way not to infringe the rights of the accused persons and not to throttle economic activities including the flow of legitimate foreign investments into Tanzania.

This paper generates insightful information to policymakers, law enforcers, regulators and other stakeholders who undertake activities to tackle money laundering and its control in Tanzania and researchers who study these issues for purposes of providing understanding of the problem and facilitating policy and legal reforms. The paper raises issues that can be explored further in future and contribute to the discourse on money laundering and its control in Tanzania.
