Apart from the health aspects and the high death toll, the COVID-19 pandemic has, since its official recognition in March 2020 caused may social and economic problems. It has also led to many environmental ones. For instance, the lockdowns have led to higher levels of consumption of packaged products, and of take-away food. This paper reports on an international study on the increased consumption and subsequent changes in the amounts of waste produced since the COVID-19 pandemic. The results show that 45-48% of the respondents observed an increased consumption of packed food, fresh food, and food delivery. One of the main reasons for the increased waste generation during the lockdown was the fact that people have spent more time at home. In addition, increases of 43% and 53% in food waste and plastic packaging. Drawing from comparisons on the amount of domestic waste produced before and during the pandemic, the findings suggest that some specific types of municipal waste have visibly increased, putting additional pressure on waste management systems. This characterises one of non-intended effects of the COVID-19 pandemic. The results from this study provide useful insights to city administrations and municipal utilities on consumption patterns during emergency situations. This, in turn, may support more systemic and strategic measures to be taken, so as to curtail the increase of household waste during pandemic situations.

The literature on the potential impacts of climate change on the health of outdoor workers has received limited attention as a whole, and in sub-Saharan African countries in particular. Yet, substantial numbers of workers are experiencing the health effects of elevated temperature, in combination with changes in precipitation patterns, climate extremes and the effects of air pollution, which have a potential impact on their safety and wellbeing. With increased temperatures within urban settlements and frequent heats waves, there has been a sudden rise in the occurrence of heat-related illness leading to higher levels of mortality, as well as other adverse health impacts. This paper discusses the impacts of extreme heat exposure and health concerns among outdoor workers, and the resultant impacts on their productivity and occupational safety in tropical developing countries with a focus on Sub-Saharan Africa, where there is a dearth of such studies. Aside from the direct effects caused by extreme heat exposure, other indirect health hazards associated with increasing heat among this group includes exposures to hazardous chemicals and other vector-borne diseases. In addition, reduced work capacity in heat-exposed jobs will continue to rise and hinder economic and social development in such countries. There is an urgent need for further studies around the health and economic impacts of climate change in the workplace, especially in tropical developing countries, which may guide the implementation of the measures needed to address the problem.

Private universities are important actors in higher education, and also play a key role in the sustainability debate. But despite their importance, there a shortage of research on how sustainability is being implemented at private universities. Based on the need to address this gap, this paper investigates the nature and diversity of sustainability-based practices undertaken at private universities. It outlines the ways private universities see and perceive sustainability, and examines by means of a survey involving 10 universities from across all geographical regions which educate over 150.000 students, how these universities incorporate sustainabilityrelated practices, as part of their operations. The results suggest that, unlike their public counterparts, about half of the respondents stated that they do not have projects undertaken to promote sustainability in local communities or in their respective regions. Also, some private universities perceive themselves as leaders in sustainability in higher education, while some are still developing a more robust sustainability profile. The conclusions of the paper are that the special features related to sustainable development teaching and research at private universities need to be better identified, in order to involve them more on sustainability efforts. Also, whereas many of them are highly engaged on improving energy efficiency, reduce greenhouse gas emissions, promote sustainable water usage and promote sustainable landscaping, there is a need for them to also engage in other areas. Finally, private universities should engage on further efforts to increase their sustainability activities, which are beneficial to them in financial terms, as well as in respect of their image and the greening of their operations.
