The COVID-19 pandemic has impacted all sectors of the tourism industry, particularly air transportation. However, air transport remains an important contributor to economic growth globally. Thus, this study examines whether air transport (a proxy for tourism) stimulates economic growth to validate the air-transportation-led growth hypothesis (ALGH) in the Australian context. To conduct the study, we analyse the asymmetric long-run and short-run impacts of the air passengers carried (a proxy for tourism) on the gross domestic product (GDP) in Australia. We use the nonlinear autoregressive distributed lag (NARDL) modelling approach on data for Australia from 1971 to 2019. We also examined the effects of selected control variables (i.e., energy consumption, financial development, socialisation, and urbanisation) on economic growth. In both the short and long run, we observed statistically significant asymmetric impacts of air transport on economic growth. The positive shocks in air transport propel the long-term growth of Australia’s economy. Additionally, according to the findings, negative shocks of air transport have a stronger detrimental impact on economic development than positive shocks.

COVID-19 has changed the permeability of borders in transboundary environmental governance regimes. While borders have always been selectively permeable, the pandemic has reconfigured the nature of cross-border flows of people, natural resources, finances and technologies. This has altered the availability of spaces for enacting sustainability initiatives within and between countries. In Southeast Asia, national governments and businesses seeking to expedite economic recovery from the pandemic-induced recession have selectively re-opened borders by accelerating production and revitalizing agro-export growth. Widening regional inequities have also contributed to increased cross-border flows of illicit commodities, such as trafficked wildlife. At the same time, border restrictions under the exigencies of controlling the pandemic have led to a rolling back and scaling down of transboundary environmental agreements, regulations and programs, with important implications for environmental democracy, socio-ecological justice and sustainability. Drawing on evidence from Southeast Asia, the article assesses the policy challenges and opportunities posed by the shifting permeability of borders for organising and operationalising environmental activities at different scales of transboundary governance.

There is a pressing need to accelerate the development of advanced technologies to prevent Coronavirus in large gatherings. The present system is an integration of tunnel disinfectant spray system and solar setup which utilises the solar energy to power a pump which pushes the required amount of chemical mixture into the nozzles of the spray system in order to eliminate any incoming virus or bacteria on the clothes of a particular person without wetting it. Data was gathered for a mall in New Delhi related to occupancy levels before and after lockdown. A 47% and 35% spike in energy and disinfectant mixture to pump was evaluated on weekends. A 70% reduction in operating cost was registered for solar based system in comparison to non-solar setup. Optimum conditions by considering efficiency and cost effectiveness evaluated are 8 number of nozzles, nozzle angle 55 degrees spray pressure 200 bar, and pressure 200 bar.

This study examines the association between environmental sustainability, governance factors and national culture with COVID-19 impact. We aim to draw implications for thinking and researching environmental accountability at a higher level than the organisation. We draw on the conceptual lens of deep ecology. Using a sample of 44 countries, we find that that countries with a higher level of corporate carbon emissions experienced a greater impact from COVID-19. Moreover, countries with higher accountability and government effectiveness are associated with a lower COVID-19 impact, implying that productive policy responses to the pandemic were employed in such settings. The study also finds that the positive association between carbon emissions and COVID-19 impact is less pronounced for countries with an individualism culture. This suggests that policy responses, such as social distancing, may have yielded better results in these cultural contexts. Furthermore, it is found that the positive impact of carbon emissions on COVID-19 impact is lower for countries having long-term orientation and environmental value orientation cultures.

The purpose of this study was to identify and exhibit the interrelationships among COVID-19’s impacts on supply chain activities. Based on a literature review and the manager’s input, twenty COVID-19 impacts were collected. An integrated approach of exploratory factor analysis (EFA) and grey-decision-making trial and evaluation laboratory (G-DEMATEL) was used to reveal the causal interrelationships among the COVID-19 impacts. Initially, a questionnaire survey was administered among 220 respondents for EFA. Based on the outcome of EFA, the twenty COVID-19 impacts were categorized into seven critical areas. Then, based on the experts’ inputs, G-DEMATEL was utilized to reveal the causal interrelationships among various COVID-19 impacts. The results indicate that disruption management, relationship management, and production management are the top three critical areas that need to be addressed in the COVID-19 crisis. Disruption in supply, ripple effect on supply chain operations, and obsolescence of machines were found to be the most influential impacts while disproportionateness between supply and demand, difficulty in demand forecasting, and reduced cash inflow were found to be the most influenced impacts. This study’s outcomes will help policymakers and supply chain managers develop strategies to restructure supply chain networks. This study is an original contribution to the analysis of COVID-19 impacts in the supply chain activities in India due to the use of EFA and G-DEMATEL. This study considers India only, and hence, the outcomes lack generalizability. A study considering multiple developing countries could generalize these findings.

Geopsychiatry, a newly emerging discipline within psychiatry, examines the influence of geopolitical determinants on mental health and mental illness. Geopolitical determinants include conflict and wars, global austerity, climate change, public health crises (such as the coronavirus disease 2019 (COVID-19)), and migration. This study focuses on the two significant areas of climate change and migration. Climate change can affect mental health directly or indirectly in a variety of ways, including chronic (global warming) and acute (heat waves and environmental disasters) events. Certain groups of migrants, including migrating children, older migrants, refugees, and asylum seekers, are particularly vulnerable to developing psychiatric disorders. The convergence of climate change and migration is significantly complicating the already highly difficult situation for mental health services worldwide, particularly in low- and middle-income countries where access to care is limited. Despite this, the majority of studies examining mental health impacts of these events originate from high-income countries, and there is still a lack of effective preventive and treatment strategies. In 2023, the World Psychiatric Association (WPA) set up a Special Interest Group on Geopsychiatry with a clear and explicit aim to summarize current evidence and propose strategies to tackle geopolitical challenges on mental health. The Special Interest Group aims to support regional and local groups across all psychiatric disciplines and stakeholders dedicated to building local consensus, prioritizing research, crafting policies, and collating and sharing good clinical practices. With such significant effort, we can expand our understanding and collaboration on geopsychiatry and make changes to the care of people with geopolitical and mental health challenges around the globe.
