Overcoming seed dormancy of senegalia galpinii and vachellia robusta through scarification pre-sowing treatments.
(Semantic Scholar, 2020-03-30)
The seeds of Senegalia galpinii (Burtt Davy) Seigler and Ebinger and Vachellia robusta (Burch.) Kyalangalilwa and Boatwright have hard coatimposed dormancy that prevents water and air from entering the seeds, which is ...
Forest resource utilisation and rural livelihoods : insights from Chobe enclave, Botswana.
(Routledge Taylor & Francis Group, 2020-01-31)
For centuries, developing countries have been immensely dependent on environmental resources, forests included. Despite the established contribution of forests to livelihoods, the level of communities’ reliance on forest ...
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. ...
Community Perspective on State Forest Management Regime and its Implication on Forest Sustainability: A Case Study of Chobe Forest Reserve, Botswana
(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 ...
Dam Water Level Prediction Using Vector AutoRegression, Random Forest Regression and MLP-ANN Models Based on Land-Use and Climate Factors.
(MDPI, 2022-11-11)
To predict the variability of dam water levels, parametric Multivariate Linear Regression (MLR), stochastic Vector AutoRegressive (VAR), Random Forest Regression (RFR) and Multilayer Perceptron (MLP) Artificial Neural ...
Spatial variability of aquatic macroinvertebrate assemblages in the Okavango Delta, Botswana: considerations for developing a rapid bioassessment tool
(Taylor & Francis, 2020-07-02)
Spatial variability in macroinvertebrate assemblages of the Okavango Delta, Botswana, was examined to evaluate differences in assemblages at a regional and habitat scale. Sampling was undertaken six times during a one-year ...
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, ...
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 ...
