(Elsevier, 2022-04)Study region This study is conducted over the Notwane Catchment Area (NCA) in South eastern Botswana using geospatial and geophysical tools. Study focus Geospatial and geophysical tools, which provide spatial information ... -
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 ... -
Identification of the causal agent of sorghum leaf blight and evaluation of its current management practices in Pandamatenga farming area
(Academic Journals, 2008-01-20)In Botswana, cattle rearing can either be in farms or in communal grazing areas. In communal grazing areas, carrying capacities are never adhered to, hence degradation sometimes occurs. This negatively impact on the ... -
Land reforms that exclude the poor: the case of Botswana.
(Taylor & Francis Online, 2008-09-03)Land reforms in Botswana, unlike those in other southern African countries, were not undertaken with the primary objective of redistributing land, but rather with the three objectives of increasing agricultural productivity, ... -
Variation in ground dwelling insect assemblages on five habitats at Sebele content farm in Gaborone, Botswana.
(Indian Journals, 2012-09-15)A study was conducted at Sebele content Farm in Gaborone, botswana to investigate the effects of different agricultural land uses on species richness, diversity and abundance of ground dwelling insects. The agricultural ... -
The effect of temperature during cone and seed development on primary dormancy of Scots pine (Pinus sylvestris L.) seeds
(Springer, 2021)Scots pine (Pinus sylvestris L.) seeds have variable levels of primary dormancy which reflect within-species adaptation to local environments. The objective of this study was to use a thermal time approach to determine ... -
Response of Aspen Suckers to Simulated Browsing.
(Oxford Academic, 2014-04-02)Heavy and repeated ungulate browsing on reproductive suckers has limited quaking aspen (Populus tremuloides Michx.) regeneration on many Western landscapes. However, little is known about the specific effects of season and ... -
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 ... -
A case for gender equity in governance of the Okavango Deltafisheries in Botswana
(Wiley Online Library, 2012-05-22)Fish is a major source of livelihood for the majority of people living around the Okavango Delta in north western Botswana. Gender dynamics and governance regimes determine differential access to, and control of, resources ... -
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 ... -
Potential impacts of biofuel development on food security in Botswana: A contribution to energy policy.
(Elsevier, 2012-01-20)Biofuel development continues to be a critical development strategy in Africa because it promises to be an important part of the emerging bio-economy. However, there is a growing concern that the pattern of biofuel development ... -
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 ... -
Spatial refuges buffer landscapes against homogenisation and degradation by large herbivore populations and facilitate vegetation heterogeneity.
(Sabinet African Journals, 2017-08-16)Environmental heterogeneity across savanna landscapes, including different seasonal resources at different distances to water, may play a critical role in maintaining the size and diversity of wildlife populations and the ... -
