Environmental variability and the fishery dynamics of the Okavango delta, Botswana: the case of subsistence fishing
(Wiley, 2009-02-03)The hydrological regime of the Okavango River Basin is the main driver of ecological change in the delta. The delta supports a small-scale fishery which is a source of livelihood for communities within its fringes. The ... -
Essential mineral content of common fish species in Chanoga, Okavango Delta, Botswana
(Academic Journals, 2015-09)Developing countries remain overwhelmed by nutritional problems caused mainly by poverty, natural disasters and political instabilities. The aim of this study was to determine essential mineral content of some common fish ... -
Estimation of Likely Impact of Climate Variability on Runoff Coefficients fromLimpopo Basin using Artificial Neural Nefwork (ANN)
(Disaster Prevention Research Institute KYoto University., 2005-01-12)Forecasting future response behaviour of a semi-arid catchment in terms of runoff coefficient being trivial, an attempt has been made io apply an Artificial Neural Network (ANN) model to-forecast the run off coefficients ... -
Evaluating bank technical efficiency in SADC region.
(Elsevier Ltd, 2024-03-30)Efficiency is generally defined as the capacity to deliver desirable results with little effort or input. A bank cannot afford to allocate limited resources at random in a competitive market. Only once the efficiency factors ... -
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 ... -
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 ... -
Extraction of Pesticides from Plants using Solid Phase Microextraction and QuEChERS
(South African Journal of Chemistry, 2013)A study employing dispersive solid phase extraction in the formof the quick, easy, cheap, effective, rugged and safe (QuEChERS) method and solid phase microextraction (SPME) for the cleanup of pesticides in plant samples ... -
Farmers’ planting and management of indigenous and exotic trees in Botswana: implications for climate change mitigation.
(Business Perspectives [Commercial Publisher], 2015)Natural woodlands provide majority of rural population with energy source, food, building material and fodder for livestock. However, current developments and population growth have exerted enormous pressure on the woodlands ... -
Firewood Utilisation and Its Implication on Trees around Mopipi Village in Boteti Sub-District of Botswana.
(2018-09-13)A household survey was done to assess the number of people using firewood in order to determine the amount of available firewood, its rate of utilisation and the distance travelled per selected household. There are a total ... -
Fish, Floods, and Ecosystem Engineers: Aquatic Conser- vation in the Okavango Delta, Botswana.
(American Institute of Biological Sciences, 2009-01-01)The Okavango Delta, Botswana, is a major wetland surrounded by the Kalahari Desert. The delta supports a diverse fish fauna that depends on highly seasonal flooding from inflowing rivers, and on the actions of ecosystem ... -

A flood pulse driven fish population model for the Okavango Delta, Botswana.
(Elsevier, 2012-03-10)The Okavango Delta is a large, remote, and ecologically significant wetland located in Botswana that receives a strong annual flood pulse. Although the hydrology in flood pulsed systems is often theorized to drive fish ... -
Food webs and energy fluxes on a seasonal floodplain: The influence of flood size
(SpringerLink, 2007)The world’s largest inland delta, located on the Okavango River in Botswana, faces major changes in the annual flooding size and duration due to climatic shifts and increased water use. We examined several parameters of a ... -
Forest Dependency and Its Implication for Protected Areas Management: A case Study From Kasane Forest Reserve, Botswana
(Springer, 2009-04-15)Conservation of biodiversity in protected areas will be more challenging if local communities are heavily dependent on them for various products and subsistence needs. This study estimated forest dependency and identified ... -
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 ... -
Functional heterogeneity of habitats and dry season forage variability in an Okavango Delta landscape, northern Botswana.
(Elsevier, 2021-08-27)The late dry season is a period when forage resources become limited in some African savannas that can induce a strong demographic bottleneck in herbivore populations with limited access to resource heterogeneity. This ... -
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 ... -
