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 ... -
Natural resources assessment in the Okavango Delta, Botswana: Case studies of some key resources
(Wiley, 2005-02)This article makes an assessment of the following key natural resources in the Okavango Delta: arable land, basket-making resources, fish stocks, and river reeds. Non-data-intensive socio-economic indicators (as opposed ... -
Spatial variability of measured soil properties across site‐specific management zones
(Soil Science Society of America Journal, 2005-09)The spatial variation of productivity across farm fields can be classified by delineating site‐specific management zones. Since productivity is influenced by soil characteristics, the spatial pattern of productivity could ... -
Rebrowsing by elephants three years after simulated browsing on five woody plant species in northern Botswana
(Southern African Wildlife Management Association (SAWMA), 2005-11-10)Utilization by the African elephant (Loxodonta africana) of five tree species of different acceptability was assessed on trees used three years earlier in a simulated browsing experiment. The experiment included two levels ... -
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 ... -
Community-Based Natural Resource Management and Tourism Partnership in Botswana: Which Way Forward?
(The Botswana Society, 2008)This exploratory study uses two case studies of the Chobe Enclave Community Trust (CECT) in Chobe District and the Sankuyo Tshwaragano Management Trust (STMT) in the Okavango Delta area of Botswana to examine the ... -
A rapid assessment of macroinvertebrates associated with Salvinia Molesta in Moremi game reserve, Okavango delta
(Idodo Umeh Publishers Ltd, 2008)Salvinia molesta is an invasive species in the Okavango Delta. The plant forms monotypic covers in places where it occurs and thus affects macroinvertebrates diversity within them. Three habitats with low, moderate and ... -
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 ... -
A synthesis of multi-disciplinary research in precision agriculture: site-specific management zones in the semi-arid western Great Plains of the USA
(Springer Link, 2008-03-03)Researchers from Colorado State University, in collaboration with scientists from the United States Department of Agriculture (USDA), initiated a long-term multi-disciplinary study in precision agriculture in 1997. ... -
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, ... -
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 ... -

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 ... -
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 ... -
Vegetation patterns and nutrients in relation to grazing pressure and soils in the sandveld and hardveld communal grazing areas of Botswana.
(Taylor & Francis Online, 2009-11-12)A major challenge confronting managers of extensive grazing systems is uneven use of herbaceous forage plants by livestock. The concentration of grazing in preferred areas or around foci points (e.g., water points) eventually ... -
