RESUMO
Current conceptualizations of nature-based solutions have so far served to characterize-and reproduce-cost-effective remedies, particularly in cities of the global north. Yet nature-based solutions (NbS) are fundamental to the production of urban resilience. Focusing on Ghana's second largest city, Kumasi, this research (i) examines climate literacy and explores the existing nature-based solutions towards climate change adaption; (ii) examines the perception on existing NbS and the barriers to building climate resilience via NbS; and (iii) explores ways of promoting the implementation of NbS to build climate resilience. It addresses these objectives drawing from secondary data, 367 household surveys and 7 agency interviews. The findings show that about two thirds (63%) of urban residents in the case study area are climate illiterate, and this has affected the slow uptake of nature based solutions as climate management intervention. The urban residents acknowledge the importance of nature based solutions but identify barriers such as poor consideration of the role of natural infrastructure and their incorporation in the planning process, inadequate technical capacity and guidance for incorporating NbS in climate planning, high cost requirements of NbS interventions, disparate interests from various institutions, and a general lack of knowledge, appreciation and interest from urban residents. The study concludes that mainstreaming and upscaling NbS in urban systems will require major investments which should vary from one city to the other depending on perculiar needs.

Electronic waste (e-waste), often dominated by the informal sector, has had adverse effects on recipient developing countries' economies, health and physical environment. Ghana, over the years, has had support from international organisations to manage its e-waste crisis. Until 2016, there was no e-waste specific policy to guide the management of the sector. In 2016, Ghana passed a regulatory policy - Act 917 - to specifically deal with e-waste, supported by other frameworks such as a regulatory instrument (L.I. 2250), a technical guideline for environmentally sound e-waste management and an e-waste-specific policy, which is currently being developed. However, there is dearth of research on how effectively a regulatory policy such as Act 917 can help address an informally dominated sector whose crude recycling approaches have had great environmental and health impacts. Adapting the analytical framework and intervention theory, key stakeholders within the e-waste sector were interviewed on: the effectiveness of the Act, the challenges confronting them and their involvement in the design and implementation processes. The findings showed that stakeholders were represented at various stages of the process. Informal recyclers were provided with training programmes, health centres and an incentive scheme to minimise burning of electrical and electronic equipment. There however exist many challenges to the sound management of the sector, particularly, the lack of end-to-end recycling facilities, registering and formalising the sector and sequencing of the e-waste policy and regulatory framework. The research concludes by recommending areas for future studies.
RESUMO
The purpose of this paper is twofold: to explore the factors influencing the emergence and growth of informal e-waste activities and to examine workers' motivation for involvement in informal e-waste activities. Semi-structured interviews and observations among actors in the recently established Dagomba-Line e-waste site in Kumasi, Ghana were employed to gather relevant data. Emergence and growth of e-waste activities are largely influenced by spatial, political, socio-cultural and economic factors. The reuse and open disposal of e-waste are the common practices due to the cost of transportation to a final disposal site. Similar to findings at the well-established Agbogbloshie e-waste site, also in Ghana, scavengers are found at the bottom of the e-waste financial ladder. The major motivating factor for engaging in e-waste handling is poverty. Additionally, some respondents mentioned the lucrative nature of the activity, landlessness, and peer influence as a motivation. The results showed that younger workers (below 35 years) were more likely to be engaged in the activity for reasons of peer influence and poverty and major source of livelihood . The paper recommends that policy and planning should reflect ways of delivering and creating stable socio-economic conditions that promote an inclusive and sustainable development.

The study examines the nature of activities and assess knowledge on occupational safety and health (OS&H) risks and practices among solid waste collectors in two low-income informal neighbourhoods in Kumasi (Aboabo and Asawase). Using observations and semi-structured interviews with 83 participants and relevant institutions, the findings indicate that informal tricycle waste collectors provided spot-to-spot waste collection using improvised sirens to signal their arrival. Workers generally had low knowledge, expressed less about occupational health risks, and thus adopted less safe work practices. The study however showed significant differences between knowledge of health risks (p < 0.000, R = 0.83) and years of working experience (p < 0.01, R = 0.74) and adoption of safe practices. Workers who had knowledge the associated health risks of the activity and also have been in the activity for more than 2 years were more likely to use at least one PPE/PPC. The study recommends that targeted interventions to mitigate risks and improve the health and safety of workers require effective risk communication. The study concludes that insight into OS&H is important to offer opportunities for better waste management strategies in the informal urban areas.
