(Taylor & Francis, 2023)Informing Africa’s tourism sector responses to the IPCC-AR6’s projected climate change impacts remains paramount. This study reviews the evolution of knowledge on climate change and tourism in Africa, examining gaps, ... -
Agrotourism as peripheral and ultraperipheral community livelihoods diversification strategy: Insights from the Okavango Delta, Botswana
(Elservier, 2023)The potential of agrotourism for livelihoods diversification in remote (peripheral) and extremely remote (ultraperipheral) traditional, agrarian communities is indeed a testament of its uniqueness to enhance rural ... -
Water abstraction of invasive Prosopis juliflora and native Senegalia senegal trees: A comparative study in the Great Rift Valley Area, Ethiopia
(Elservier, 2023)Besides direct water abstraction, natural water scarcity in semi-arid and arid regions may be further exacerbated by human-assisted changes in vegetation composition, including the invasion by non-native plant species. ... -
Ecological interactions, local people awareness and practices on rodent-borne diseases in Africa: A review
(Elservier, 2023-02)Several anthropogenic activities exposure humans to the risk of rodent-borne diseases. These activities are but not limited to logging, clearing land for crop cultivation, and consuming rodents. Rodents are a highly diverse ... -
Allometric models for estimating biomass storage and carbon stock potential of Oldeania alpina (K. Schum.) Stapleton forests of south-western Ethiopia.
