Modelling the spatial pattern of forest fires using NDVI and land surface temperature in Southern African landscapes
(2014-10-07)In this study we used maxent to test whether; and for which month of the growing season SPOT derived normalized difference vegetation index (SPOT NDVI) data can be used to predict fire occurrence in August, September and ... -
Spatial modelling of water pipe bursts in Harare, Zimbabwe
(2014-10-07)Water is a scarce commodity whose availability and utilisation requires diligent planning, distribution and management to ensure its proper use and protection in the interest of humankind and other ecological balances. ... -
Variations in groundwater quality in protected and unprotected water sources of Murehwa district
(2014-10-07)Target 7C of the Millennium Development Goals is aimed at halving the proportion of people without sustainable access to safe drinking water and basic sanitation by 2015 (UNDP, 2002). Therefore, implementation of water ... -
Spatial distribution of elephants (LOXODONTA AFRICANA) in Hwange Mining Concession area
(2014-10-07)In this study we tested whether and how environmental factors such as distance from water points inside mine dumps, distance from water points outside mine dumps, distance away from settlements, distance away from ... -
Remote sensing of waterhole distribution and its impact on wildlife and livestock interactions across a gradient of land use in a Southern African savanna
(2014-10-07)Arid and semi-arid ecosystems are water limited ecosystems. Thus, understanding the spatial and temporal dynamics in water availability is critical. In this study, we tested whether and to what extent we can use remotely ... -
Modelling spatial variations in wood volume and forest carbon stocks in dry forests of Southern Africa using remotely sensed data
(2014-10-07)The estimation of forest carbon is important to generate knowledge on the extent to which forests contribute to climate change mitigation. Several studies on the estimation of forest carbon stocks have mainly focused on ... -
Modelling of the response of sable antelope (Hippotragus niger niger) to trophy hunting: A GIS and remote sensing approach
(2014-10-07)The main objective of this study was to test the impact of hunting on sable (Hippotragus niger niger) habitat selection using a combination of satellite remotely sensed data and GIS based spatial analysis. Firstly, we ... -
Remote sensing patterns of net primary productivity in the Great Limpopo Transfrontier Conservation Area (GLTFCA) in relation to land use and land tenure
(2014-10-07)Net Primary Productivity (NPP) is an important indicator of ecosystem health and its estimation and understanding of factors determining its spatial and temporal variations is critical. Previous studies have mainly ... -
Habitat fragmentation, tree species diversity and land cover dynamics in a resettlement area in Chimanimani district of Zimbabwe : a spatio-temporal approach
(2014-10-07)Agricultural expansion into forests leads to habitat fragmentation and the creation of habitat patches that can only support a limited amount of biodiversity. Adopting theoretical frameworks which seek to understand ... -
A cloud computing architechure for e-learning plaform, supporting multimedia content
(2014-07-25)E-learning based platforms that support multimedia content to enhance interactive learning demands large disk space. Despite research ground covered under e-learning circles, less attention has been devoted to solicit ... -
Nutritional content, phenolic compounds composition and antioxidant activities of selected indigenous vegetables of Zimbabwe
(2014-07-21)Foods of plant origin may contain many phytochemical compounds such as phenolic compounds in addition to commonly identified nutrients. Interest in phenolic compounds has greatly increased recently because these ... -
Spatial variation in vegetation and soils around artificial watering points in Hwange National Park
(2014-07-17)Piospheres are examples of the spatial impacts animals have on their environment. They tend to develop around artificial watering points, particularly in the dry season. The present study sought to assess impactof ... -
A study of the biological and economic factors affecting the kapenta (Limnothrissa miodon) population and yield in Lake Kariba
(2014-07-17)This study investigated some of the variables that influence the fishery of Limnothrissa miodon (kapenta) in Lake Kariba, namely, biological (limnological factors, zooplankton composition and densities) and economic ... -
Limnological study of Malilangwe reservoir in the South-eastern lowveld of Zimbabwe
(2014-07-17)The study provides a nine month record of the limnological investigation of the Malilangwe reservoir between February to October 2011. Malilangwe reservoir is large (211 ha), and shallow (mean depth 4.54) reservoir situated ... -
Comparison of macrobend losses in Single Mode Fibre (SMF) and Multimode Fibre (MMF)
(2014-07-17)A comparison of macrobend losses in Single Mode Fibre (SMF) and Multimode Fibre (MMF) is presented. The increased demand on information has seen optical fibres slowly replacing the use of copper coaxial cables for signal ... -
A universal electronic payment model in Zimbabwe integrating with Small and Medium Enterprises and working with mobile databases
(2014-07-17)Electronic payment systems are proliferating in banking, retail in government and everywhere money needs to be exchanged. Electronic payment systems are the everyday technology under use, they are the relevant systems ... -
Characterising Silicon Diode response for radiation measurements
(2014-07-17)X-ray radiation has been used in the treatment of cancer since its discovery in 1895. It was found that incorrect use of x-radiation can cause irreversible damage. It was necessary to introduce diode in-vivo dosimetry ... -
A cognitive principle based instructional design for conceptualization of computer concepts
(2014-07-17)The increasing development of computer technologies has made multimedia learning an important learning and instruction strategy. The multimedia design alone, however, does not necessarily result in significant positive ... -
Spatial and temporal heterogeneity of woody vegetation along park boundary and the possible causes: A case study of Umfurudzi Game Park and adjacent communal lands
(2014-07-10)Although national parks have been established across Africa to protect areas from deforestation and to conserve biodiversity, they are not immune to disturbances outside and inside their boundaries. A study on spatial ... -
Evaluating the relative contribution of changing farming methods to habitat loss in the mid-Zambezi Valley, Zimbabwe
(2014-06-27)Agriculture expansion is a major contributor to wildlife habitat loss in the ecological frontier areas. However, little is known about the contribution of different crops to wildlife habitat loss. In this study we evaluated ...
