The paper analyzes the current state of plastic value chains in Africa and potential digital innovations adopted by African entrepreneurs to contributing a circular economy. We provide an overview waste trade countries assessment existing solutions that can support transition findings show various are being applied including web-based solutions, mobile apps 3D printing. case studies also multinational companies, especially consumer facing brands, major players national countries, acting as...
In this paper, a methodology is proposed for identifying the best equations estimating time of concentration (ToC) watersheds located in specific geographic region. The primarily works on basis modifying available to minimize their bias any particular region interest. methodology, each watershed, ToC considered as "reference" determined using Natural Resource Conservation Service (NRCS) velocity method employed TR-55 model and information systems data. Moreover, ranking-based selection...
Socio-technical niche innovations offer significant opportunities to accelerate Africa's transition a circular plastic economy. However, information on how these can be operationalised is fragmented, and stakeholder networks appear significantly under-developed the continent. This paper applies multi-level perspective of socio-technical transitions theory analyse shift from linear plastics system economy enabled by digital innovations. Drawing an inter-sectoral engagement with 151...
The evaluation of water resources management practices is essential for usage decisions in regions with limited resources. literature provides numerous assessment frameworks, but many ignore the unique characteristics and conditions some special arid semi-arid regions, such as Gulf Cooperation Council (GCC) countries, which lack any permanent rivers or lakes. Thus, this study, first a two-part series, seeks to develop conceptual Sustainable Water Resources Management Assessment Framework...
Purpose This paper aims to provide insights into the environment needed for advancing a digitally enabled circular plastic economy in Africa. It explores important technical and social paradigms transition. Design/methodology/approach study adopted an interpretivist paradigm, drawing on thematic analysis qualitative data from inter-sectoral engagement with 69 stakeholders across continent. Findings The results shows that, while substantial progress has been made regard development deployment...
The development of a Bayesian modeling approach for estimation the age distribution groundwater using radioactive isotopes and anthropogenic chemicals is described. model considers uncertainties associated with measured tracer concentrations as well parameters affecting concentration tracers in groundwater, it provides posterior probability densities defining Markov chain Monte Carlo method. also incorporates effect dissolution aquifer minerals on diluting 14 C signature this process...
Water shortage is a concern in arid and semi-arid regions across the globe due to their lack of precipitation unpredictable rainfall patterns. In past few decades, many frameworks, each with own criteria, have been used identify rank sites for rainwater harvesting (RWH), process which critical improvement maintenance water resources, particularly regions. This study reviews present state art site selection such identifies areas additional research. The results systematic review performed...
Abstract The water crisis is a critical issue, particularly in arid and semi-arid regions where rainfall limited. Rainwater harvesting systems have been introduced many locations to capture what does occur, but selection of the optimum site vital ensure efficient storage. Over past few decades, range frameworks for ranking proposed rainwater sites on basis suitability suggested. goal this study was develop robust methodology extend these frameworks, which consider biophysical socio-economic...
In this paper, genetic programming (GP) is used as an effective model induction tool to solve a classic problem in open channel flow: the free overfall. By applying GP experimental data of circular channels with flat bed and employing selection procedure, reliable expression form found for calculating critical depth (hc) end-depth ratio (EDR). Further effort made verify applicability superiority other cross sections. This global not only outperforms expressions estimating depth, it also...
A Monte Carlo simulation technique was applied to assess the effect of stormwater quality volume captured by best management practices (BMPs) on frequency discharging concentrations constituents above certain designated threshold limits. The method used an assumption a power law relationship between cumulative load and flow incorporate first flush effect. exponent this considered random variable its distribution obtained from 78 measured pollutographs three urban highway sites in West Los...
Long‐term variations of streamflow in a tidal channel were measured using Fluvial Acoustic Tomography (FAT) system through one transmission path. FAT is an innovative acoustic technology that utilizes the time‐of‐travel method to determine velocity between two points from multiple ray paths traverse entire cross‐section stream. Due high spatial variability flow distribution stationary ADCP measurements not likely yield true section‐averaged and moving‐boat was therefore used provide...
