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. ...
Allometric models for estimating biomass storage and carbon stock potential of Oldeania alpina (K. Schum.) Stapleton forests of south-western Ethiopia.
(Elsevier, 2023-02)
Ethiopia has the largest bamboo resource base in Africa. However, due to the lack of species-specific models, little is known about the biomass storage, carbon stock and sequestration potential of bamboo forests. Here, ...

(Taylor & Francis Online, 2020-01-31)
Forest management regimes have evolved worldwide over time in a quest to protect and conserve forests. This paper analysed local communities’ perspectives on the existing management regime for the Chobe Forest Reserve, ...
Bee species diversity and nesting sites in cultivated savannah, northern Zimbabwe.
(Taylor & Francis Online, 2022-06-09)
Bees play key roles in savannah ecosystems but face myriad threats. A combination of flower sweep netting and visual observations was used to determine bee-species diversity and preferred nesting sites in five villages in ...
Evaluation of national disaster management strategy and planning for flood management and impact reduction in Gaborone, Botswana
(Elsevier, 2022-05)
Floods and droughts are the most common natural disasters that have and continue to result in huge economic losses and loss of life across southern Africa. Flood disasters come about due to intersection of flood waters ...
Germination studies on seeds of Burkea africana and Erythrophleum africanum from Kazuma Forest Reserve, Northern Botswana
(Academic Journals, 2020-09)
Burkea africana and Erythrophleum africanum are characterized by seed coat-imposed dormancy that prevents water entry and gaseous exchange, which are essential for the germination process. The objective of this study was ...
Urban land-use classification using machine learning classifiers: comparative evaluation and post-classification multi-feature fusion approach.
(Taylor and Francis Ltd., 2023-02-22)
Accurate spatial-temporal mapping of urban land-use and land-cover (LULC) provides critical information for planning and management of urban environments. While several studies have investigated the significance of machine ...
Determinants of Decision Making by Smallholder Farmers on Land Allocation for Small-Scale Forest Management in Northwestern Ethiopian Highlands.
(MDPI, 2022-06-03)
Smallholder farmers in the northwestern Ethiopian Highlands are highly engaged in small-scale forest management. Participation in this activity can provide a key source of income for the farmers as well as wider benefits ...
Evaluation of Germination under Different Storage Conditions of Four Endemic Plant Species from Ethiopia: Implications for Ex Situ Conservation in Seed Banks.
(MDPI, 2023-02-06)
The conservation of endemic plant species is a major concern, as the species are with restricted distribution range. Since in situ conservation alone will not guarantee their maintenance, ex situ conservation measures must ...
Analysis of Forest Cover Change and Its Drivers in Biodiversity Hotspot Areas of the Semien Mountains National Park, Northwest Ethiopia.
(MDPI, 2023-02-07)
Forests provide multiple ecosystem services ranging from local livelihoods and socio-economic benefits to global ecological services. Despite these benefits, human activities have put immense strain on forest resources, ...
