Fish, Floods, and Ecosystem Engineers: Aquatic Conservation in the Okavango Delta, Botswana
(Oxford University Press, 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 ... -
Fodder Tree Species Composition and Density in Grazing Gradients of Fenced and Unfenced Grazing Areas of the Gaborone North, Botswana.
(Cross Mark, 2017-06-23)The extent to which degradation or changes in fodder tree species composition caused by grazing pressure is critical since fodder trees form the base diet for browser such as goat as well as maintenance purposes for cattle ... -
Food and nutrition security and wildlife conservation: Case studies from Kenya.
(Academic Press, 2020-01-01)Despite concerted efforts to improve food and nutrition security in many parts of the world, food and nutrition security still remains a challenge, especially in developing countries. In the face of the increasing human ... -
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 ... -
Forage conservation in sub-Saharan Africa: Review ofexperiences, challenges, and opportunities
(John Wiley & Sons, Ltd, 2021-11-11)Forage conservation is an important potential solution to seasonal variation in feed quality and quantity and herder-farmer conflicts in sub-Saharan Africa (SSA). Considerable variations exist in the type of forages conserved ... -
Forage quality and availability for large herbivores in southern African rangelands
(Klaus Hess Publishers, 2018)In light of the growing human population, the pressure on herbivores (livestock and wild herbivores) will be accelerated, resulting in a need for eff ective land management. To achieve this, information and knowledge about ... -
Foraging strategies of sheep and goats under semi-intensive management in Botswana
(Bureau for Scientific Publications, 2004)Diet selection of sheep and goats was determined seasonally using the microhistological technique to assess their trophic diversities, diet overlapping and preferences between the two species. The trophic diversities of ... -
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 ... -
A fractional-order fall armyworm-maize biomass model with naturally beneficial insects and optimal farming awareness.
(Elsevier, 2021-11-01)Maize remains an important food crop in Africa. However, the production of this crop, and consequently the livelihood of the growers are threatened by the invasion and widespread infestation of the fall armyworm which ... -
A fractional-order Trypanosoma brucei rhodesiense model with vector saturation and temperature dependent parameters.
(Springer Open, 2020-06-11)Temperature is one of the integral environmental drivers that strongly affect the distribution and density of tsetse fly population. Precisely, ectotherm performance measures, such as development rate, survival probability ... -
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 ... -
Fuzzy Modeling for the Dynamics of Alcohol-Related Health Risks with Changing Behaviors via Cultural Beliefs.
(HINDAWI, 2020-07-13)In this paper, we propose and analyze a fuzzy model for the health risk challenges associated with alcoholism. The fuzziness gets into the system by assuming uncertainty condition in the measure of influence of the risky ... -
GASTRO-INTESTINAL NEMATODES OF GOATS REARED UNDER COMMUNAL SMALL SCALE FARMING CONDITIONS IN BOTSWANA
(Bulletin of Animal Health and Production in Africa, 2015)The study was carried out in goats reared under communal small scale farming conditions near Gaborone, Botswana, to evaluate two sample preparation methods for McMaster egg counting technique, determine worm egg counts ... -
Gender Disparities and Board Representation in Zimbabwe.
(Econjournals, 2024-12-06)Approximately one-third of the world’s GDP is held by the 500 biggest firms worldwide. Nonetheless, barely 25% of Fortune 500 board members and <6.7% of board chairs worldwide were female in 2021. The aim of this paper is ... -
Gender impact on sheep and soat production in Botswana. A case of Gaborone region
(Journal of Agriculture in the Tropics and Subtropics, 2001)A survey of 100 randomly selected farming households keeping livestock was conducted in ten randomly selected villages in the Gaborone agricultural region from October 1997 to February 1998. Data acquisition was done through ... -
Genetic characterization of tswana and tuli cattle kept at Botswana University of Agriculture and Natural Resources using microsatellite markers
(Botswana University of Agriculture and Natural Resources, 2020-10)Twelve FAO-lSAG-rccommended microsatellite markers were used to analyse genetic variation in Tswana and Tuli cattle breeds. All loci were polymorphic and a total of 75 and 77 alleles were genotyped in the Tswana and Tuli ... -
Genetic Polymorphism in the Promoter and 5 ́ UTR of HSP-70 Gene in Three Strains of Indigenous Tswana Chickens and Commercial Broilers
(Scienceline Publication, 2021-12-10)The current study was conducted to investigate sequence polymorphisms in the promoter, 5 ́untranslated regions (UTR), and partial exon regions of chicken HSP-70 gene in the normal (n = 24), naked neck (n = 22), and dwarf ... -
