“…Figure 8 presents the solar radiation received by the PV panels when inclined at an angle of 30° and horizontal. The finding that PV panel perform better at an inclination of 30°is consistent with the results of other studies [12][13][14][15][16][17][18][19]. There were variations in the intensity of solar radiation falling on the panels based on time, season, and location.…”

This article proposes an integrated solar PV refrigerator and heat pump (ISPVRHP) for Sub-Saharan African food vendors; the warm chamber would keep prepared food warm until the food is sold, while the cold chamber would minimise food spoilage. The ISPVRHP proposed in this article can cool water or other beverages and be capable of utilising the heat rejected to the atmosphere by the condenser for warming food. The ISPVRHP was modelled using ANSYS software, and the results were validated experimentally. The results show that both systems work well at peak hours, especially under more intense sun rays. The study found that the variation of incident solar radiation and ambient temperature has significant effects on the performance of the ISPVRHP; the wind speed, however, has only a minor impact on the total heat load of the system. In addition, the systems (cooling and heating) reached the desired temperatures and maintained them for long periods. The capacity of the refrigeration system can be increased by increasing the component sizes, including the PV system size. The ISPVRHP performance dropped substantially when the doors remained open for extended periods due to loss of energy through mass transfer.

“…The literature map, 14 Figure (1, indicates drivers and pressures (blue rectangles), the state of the urban environment (rectangle at the center of the diagram), and the responses (rectangle in green). Drivers and pressures include climate change (Blekking et al, 2022;Kaykhosravi et al, 2020;Bastin et al, 2019;Majumder et al, 2018). Air pollution and energy are other drivers of urban environmental crises (Chien et al, 2022;Zhang et al, 2022;Liu et al, 2015).…”

Cities are the drivers of economic growth but pollute the environment and deplete natural resources. Nature-based Solutions (NbS) and Ecosystem-based Adaptation (EbA) offer many answers to mitigate and adapt to climate change. Without understanding the threats associated with these solutions, bringing nature back to the city might cause undesired side effects such as introducing and proliferating invasive species. Contemporary literature on invasive species evolves from the urban ecology discipline. The paper explores contemporary literature to highlight the gap between ecologists and design professionals. We found that research published between 2017-2021 and indexed on Scopus that dealt with urban issues and invasive species yielded 4,556 publications, of which only 88 publications that design professionals prepared to indicate a gap between urban ecologists and design professionals explaining the persistence of the problem and concerns that ecologists raise. We conducted a bibliometric analysis. Results indicate three clusters: (1) Pressures such as climate change; (2) State urban ecosystems; and (3) Responses in the form of land use plans and urban designs. NbS and EbA are instrumental in responding to climate change. Planners must design and build cities to minimize the adverse effects of urbanization while maximizing the ecological processes by allowing nature conservation actions within urban environments. One of the criteria for evaluating design and planning alternatives is to check for the risk of introducing invasive species. Design experts must be aware of the risks of invasive species, which require research to update present guidelines and introduce the topic in the architectural and planning curricula.

“…Africa is highly vulnerable to climate change [1], which is expected to disrupt water, food, and health systems. These changes could worsen existing issues like poverty and insecurity, impacting economic development [2]. Therefore, prioritizing adaptation measures is crucial in the continent's climate policy to build resilience and reduce vulnerability.…”

Decision-makers, researchers, practitioners, and stakeholders often struggle with selecting and prioritizing strategies to manage climate change risks. While recent research extensively explores this issue, the emphasis has largely been on regions other than Africa. This is significant, considering Africa’s anticipated exposure to various and severe impacts of climate change. This study applied a two-stage model that integrates the Step-Wise Weight Assessment Ratio Analysis (SWARA) and Weighted Aggregated Sum Product Assessment (WASPAS) methods within a unique framework under the influence of spherical fuzzy (SF) conditions. In the initial stage, SF-SWARA determines the relative importance of the criteria, while the subsequent stage involves the SF-WASPAS method to rank the strategies. While the most critical challenges are limited access to finance and inadequacies in climate data, scenarios, and impact models, the solution to be considered is the promotion of a well-coordinated capacity-building programme. Furthermore, a comprehensive sensitivity analysis was conducted to validate the applicability of the proposed model. This research not only identifies and explains the challenges associated with climate change risks management in the African context but also significantly contributes to the body of knowledge by outlining and prioritizing the strategies required to address these challenges.
