Using a web-based survey conducted among 2,481 Namibian, aged 18 years or older, the factors and motivations driving individuals' decisions on marine fish consumption, spatial fish consumption, and possible strategies to promote domestic marine fish consumption were explored. Most participants (97.9%) were aware of the importance of fish in the human diet, with many preferring hake (Merluccius capensis and M. paradoxus) (31.5%) and Cape horse mackerel (Trachurus capensis) (21.7%). Most respondents (64.1%) were poor fish consumers, consuming fish once a week or once a month. Participants claimed that they mostly purchased marine fish from retail fish shops (50.7%), wholesale fish companies (18.8%), and the Namibian Fish Consumption Promotion Trust (17.4%). Factors affecting marine fish affordability in Namibia were explained with a Logit Model, with age, education, gender, monthly income, and region of residence as the explanatory variables. Responses regarding fish affordability were principally driven by age, education, and monthly income (p < 0.05). The Khomas region purchased the most marine fish (60,764.8 weighted kg) in 2019. There was a consensus across all participants that regular fish consumption is beneficial to human health; however, participants listed affordability and accessibility of marine fish as critical constraints. Results indicate that Namibian marine fish consumption is poor and needs to be promoted. Results suggest ways to stimulate marine fish consumption locally and elsewhere to meet the UN Sustainable Development Goal 2 to end hunger and alleviate malnutrition.

The Namibian energy sector and other energy sectors across the globe are currently in a rapid transformation era that must respond to climate change, which directly affects energy infrastructure’s resilience to the effects of resource scarcities or extreme weather conditions. The energy sector must implement adaptation to guarantee the resilience of vital infrastructure to fulfil its regulatory commitments, which cover the elements of resilience and safety. Through investigating climate change adaptation and mitigation implementation in Namibia, this study validates the existence of these co-benefits where integration is fully observed. It employed a meta-analysis and content analysis to link the observed variables to the most recognised co-benefits. The findings suggest that integration is an efficient way to generate co-benefits that contribute positively to the climate change project. Effective leadership support is one way of realising such integration, either via public-private partnership or energy policy. Namibian energy policy, it is suggested, through voluntary tools and incentives, should create key public-private partnerships and promote management. These recommendations have application beyond the Namibian energy sector, and the lessons learned here could be implemented in scenarios outside of it.

Municipal waste management is a major challenge for local governments in South Africa and Namibia, as in other developing countries. The circular economy concept in waste management is an alternative sustainable development framework that has the potential to combat resource depletion, pollution, and poverty while achieving the SDGs. The purpose of this study was to investigate the current waste management systems in Langebaan and Swakopmund municipalities resulting from municipal policies, procedures, and practices in the context of a circular economy. A mixed method approach was used to collect qualitative and quantitative data through structured in-depth interviews, document analyses, and direct observation. The study found that the Langebaan and Swakopmund municipalities have not yet fully implemented the circular economy concept into their waste management systems. A mix of waste consisting of papers, plastics, cans, tyres, and organic products is dumped into landfills weekly at a rate of about 85%. The main challenges to implementing the circular economy concept include: lack of technical solutions, inadequate regulatory frameworks, insufficient financial resources, lack of private sector involvement, insufficient human resource capacity, and inadequate information and knowledge. A conceptual framework was therefore proposed to guide the municipalities of Langebaan and Swakopmund in implementing the circular economy concept in their waste management systems.

If municipal solid waste (MSW) is not properly managed, harmful environmental consequences are imminent. MSW materials are rarely wasted in many affluent countries, but rather are kept in the economic cycle through circular economy models. While in many developing countries, MSW materials are discarded with little to no effort of repairing or recycling. Moving to a circular economy will drastically reduce the amount of waste currently disposed of. This study examines how the Swakopmund Municipality in Namibia’s present municipal solid waste management techniques could be adjusted toward sustainability to reap environmental and socioeconomic benefits from the trash. Source reduction, separation at source, and recycling are some of the most effective strategies in the circular economy models that will help achieve the United Nations (UN) Sustainable Development Goals (SDGs). Swakopmund Municipality should invest in infrastructure, techniques, and programs that are within the circular economy model as an emerging system for sustainability.
