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 ...
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 ...
Effects of different silage preservatives on silage quality of pennesitum purpureum harvested at different harvesting periods.
(Scienceline Publishers, 2011)
The study was conducted to determine the effects of preservatives on the chemical composition of elephant grass (P. purpureum Bana cv.) harvested from N-fertilized and unfertilized treatments at different periods (3, 6 and ...
The tropical African mercury anomaly: Lower than expected mercury concentrations in fish and human hair.
(Elsevier, 2011-02-20)
Mercury is a neurotoxin and global pollutant, and wetlands and newly flooded areas are known to be sites of enhanced production of monomethylmercury, the form of mercury that is readily biomagnified in aquatic food chains ...
Socio-economic factors influencing household forest dependency in Chobe enclave, Botswana.
(Springer Open, 2017)
Introduction: Human dependence on forests is a multifaceted phenomenon. The degree of reliance on forests varies geographically, overtime and across communities. These dynamics underpin the importance of understanding the ...
“Where there is water there is fish” – Small-scale inland fisheries in Africa: dynamics and importance
(2015)
The importance of fish, and in particular small fish, for sustainable and healthy livelihoods in Africa, as well as their strong relationship with climate driven water dynamics are generally undervalued and little understood ...
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, ...
