For major air transport in and out of the African continent, African travellers rely mainly on non-African Airlines. There is, however, one successful airline on the continent at the writing of this paper: Ethiopian Airlines and the Ethiopian Aviation Group. Why are no further successful airlines possible on a continent of 1.4 billion people (25% of the world’s population) and only a 2%-share of global air transport? At the introduction of SAATM, which is anticipated as the start of the domestic African aviation boom, most African countries seem unprepared to build a success story like Ethiopia. Transportation infrastructure in sub-Saharan Africa does not start with roads and rail but with runways and airlines. This research investigates the basic requirements needed to equip Africa with a competitive aviation industry that would contribute some 5% to the continent’s GDP and create hundreds of thousands of workplaces. Interviews with African SAATM leaders signal a slowdown in the effort to succeed. The research is also concerned about the lack of inclusion in the implementation of a NetZero CO2 emission scheme in Africa.展开更多

文摘Background and objectives:Propolis is a resinous material produced by honeybees.Its chemical composition is highly complex and varies significantly depending on geographic region and season.This intrinsic variability presents challenges to the standardization and quality control of propolis.This study aimed to evaluate the chemical composition,total phenolic content,and antioxidant potential of propolis collected from seventeen geographical regions across Africa.Methods:A reverse-phase high-performance liquid chromatography(RP-HPLC)method coupled with a photodiode array detector was used for analysis of propolis samples.The flavonoid and phenolic contents of the samples were determined using colorimetric and Folin-Ciocalteu methods.Antioxidant capacity was assessed using the 2,2-diphenyl-1-picrylhydrazyl assay.Results:Five flavonoids(naringenin,pinocembrin,galangin,chrysin,and quercetin),one flavonoid glycoside(rutin),six phenolic acids(caffeic acid,p-coumaric acid,cinnamic acid,chlorogenic acid,ferulic acid,and gallic acid),and an aromatic ester-caffeic acid phenethyl ester were simultaneously detected and quantified using RP-HPLC with an ACE-5 C18 column(250 mm×4.6 mm i.d.,5μm)and photodiode array detector detector.The reference standards showed good linearity with regression coefficients(R2)ranging from 0.96 to 0.99.For precision,repeatability,and stability studies,the relative standard deviation for all reference standards was below 2.5%.The 2,2-diphenyl-1-picrylhydrazyl assay yielded EC_(50) values ranging from 17.6±0.39 to 0.16±0.001 mg/mL.Conclusions:RP-HPLC method for the simultaneous quantification of thirteen reference standards will serve as a reliable tool for the standardization and quality evaluation of propolis.The flavonoid and phenolic contents are key contributors to the antioxidant activity of propolis and reflect local plant biodiversity and bee-plant interactions within the ecosystem.
文摘This study explores the epistemic imperative to decolonize African education systems by centering indigenous philosophies such as Ubuntu and introducing the Ubuntu Pedagogy as a pedagogical model.Ubuntu pedagogy transforms teacher-learner relationships,it provides a replicable model for relational learning,community partnerships,and reassert the dignity of indigenous epistemologies.The paper examines how language,knowledge production,and pedagogy can be restructured to reflect African epistemologies and educational sovereignty.This research also explores the relationship between mother tongue instruction and cognitive access to learning.Through a qualitative literature analysis of case studies and African scholarly discourse,this paper highlights the continued marginalization of indigenous knowledge systems and the need to embed culturally relevant teaching methodologies.The findings support the broader question of whether there exists an epistemological base for knowledge independence or production within African and Afro-Diasporic contexts,revealing culturally coherent frameworks of learning that resist colonial dominance and an exploration of reclaiming African indigenous knowledge systems for educational and cultural sovereignty.
文摘As Africa marks a decade since the adoption of Agenda 2063,its bold and ambitious seven aspirations have positioned the continent as a strong,united,resilient,and influential global player and partner.Reaffirming its Pan-Africanism and African renaissance plan,aspiration seven of Agenda 2063 underscores the importance of Africa’s unity and solidarity in the face of major challenges emanating from the changing nature of globalisation,climate change,and economic and political environment.
文摘Walk the Earth By FEDERICO VERONESI Prestel This book is a powerful tribute to Africa’s last great elephants,o!ering an intimate look at these majestic animals in their wild habitats.Photographer Federico Veronesi,known for his poetic wildlife portraits,captures both the grandeur and vulnerability of elephants with striking sensitivity.His full-spread images show tuskers roaming watering holes,lakebeds,and vast savannahs,often framed by glowing skies or distant mountains.In Amboseli,Liwonde,Mana Pools,and the Chyulu Hills,Veronesi waits patiently to record fleeting moments-a matriarch leading her herd,a lone bull beneath storm clouds,or a silhouette against the fading sun.
