Background: After coronavirus disease 2019 (COVID-19) was declared a pandemic, movement restrictions were implemented across sub-Saharan Africa. There has been much speculation on what the long-term impacts on urban transport might be. Objectives: The aim of this paper is to identify the revealed and future travel impacts of the pandemic. Method: To pursue this aim, evidence was compiled from two sources: secondary big data;and a ( n = 15) two-wave Delphi panel survey of experts in the region. Results: It is predicted that longer-term impacts will take the form of: reduced travel by, and accessibility for, low-income households residing in peripheral locations because of decreased welfare;reduced transport service availability;operator reduction (particularly amongst unsubsidised formal operators);increased remote activity participation for a minority of better resourced households with white-collar workers;and disrupted trip distributions as the mix of city-centre land use changes in response to business attrition in economic recession rather than to disrupted bid rents. Conclusion: The major impact of the pandemic is likely to be on welfare, rather than on trip substitution. There is a need, therefore, to focus policy on the mitigation of these impacts and, more particularly, on ways of measuring changes in transport disadvantage and exclusion so that reliable data are available to inform mitigation strategies. The mitigation strategies considered should include investment in affordable ‘digital connectivity’ as a means of complementing accessibility from physical proximity and mobility. The pandemic also highlights the need to develop more robust transport planning practices to deal with uncertainty.

PM2.5 is an air contaminant that has been widely associated with adverse respiratory and cardiovascular health, leading to increased hospital admissions and mortality. Following concerns reported by workers at an industrial facility located in Santa Ana, California, workers and community leaders collaborated with experts in the development of an air monitoring pilot study to measure PM2.5 concentrations to which employees and local residents are exposed during factory operating hours. To detect PM2.5, participants wore government-validated AtmoTube Pro personal air monitoring devices during three separate workdays (5 AM–1:30 PM) in August 2021. Results demonstrated a mean PM2.5 level inside the facility of 112.3 µg/m3, nearly seven-times greater than outdoors (17.3 µg/m3). Of the eight workers who wore personal indoor sampling devices, five showed measurements over 100 μg/m3. Welding-related activity inside the facility resulted in the greatest PM2.5 concentrations. This study demonstrates the utility of using low-cost air quality sensors combined with employee knowledge and participation for the investigation of workplace air pollution exposure as well as facilitation of greater health-related awareness, education, and empowerment among workers and community members. Results also underscore the need for basic measures of indoor air pollution control paired with ongoing air monitoring within the Santa Ana facility, and the importance of future air monitoring studies aimed at industrial facilities.

Food industry-specific challenges such as reduced product life cycles, competitive time-to-market race and a growing need to comply with legal and voluntary quality and supply chain requirements imposed by various value chain actors have accelerated the need for innovation over the last decades. [...]the interrelation between OI and food industry is still offering several opportunities for scholars as the recent events related to the COVID-19 pandemic have highlighted the vulnerability of global supply chains and additionally pressured companies to look for different, more flexible and more collaborative approaches to innovation and new business models (Chesbrough, 2020;FAO, 2020a;Walker et al., 2021). Human resource management practices fostered the participation of employees in organizational dynamics and boosted the levels of vigour, dedication and absorption at work, stimulating their commitment in inbound and outbound flows of ideas, knowledge and skills, setting the conditions for OI. [...]the study remarks on the opportunities for agritech in becoming open, creating a tied network with supplier and including the customers in the development of new offerings.
