Auditing the spatial and temporal changes in urban cropland in Harare metropolitan Province, Zimbabwe
Urban agriculture continues to play a key role in addressing food insecurity and poverty across developing countries. This study used Landsat 5 imagery to map the spatial and temporal distribution of cropland in Harare Metropolitan in Zimbabwe using the Random Forest classifier in Google Earth Engine. Results show that the area under cultivation fluctuated considerably between 1985 and 2019 and several factors account for this trend. The results …
Modelling climate change impacts on the spatial distribution of anthrax in Zimbabwe
The study revealed that areas currently suitable for anthrax should be targeted for surveillance and prevention. The predicted future anthrax distribution can be used to guide and prioritise surveillance and control activities and optimise allocation of limited resources. In the marginally to moderately suitable areas, effective disease surveillance systems and awareness need to be put in place for early detection of outbreaks. Targeted vaccinati…
Spatio-temporal clustering of active wildfire pixels over a 19-year period in a southern African savanna ecosystem of Zimbabwe
Understanding the spatial and temporal dynamics of active wildfires is critical for supporting policies and legislation related to wildfire management. The study tested the extent to which active wildfires significantly cluster in both space and time from 2000 to 2019 using space-time scan statistics permutation model (STSSP) available in the SaTScanTM software at the 6 month and annual scales. The statistical significance of each identified clus…
Spatial modelling the effects of climate change on the distribution of Lantana camara in Southern Zimbabwe
Zhombwe (Neorautanenia brachypus (Harms) C.A.Sm.) – A recent discovery for mitigating effects of drought on livestock in semi-arid areas of Southern Africa
In semi-arid areas drought results in cattle death making people vulnerable to poverty. Drought conditions are set to increase as climate change is increasingly becoming an important threat to food security. In southern Africa, people recently discovered Neorautanenia brachypus (Harms) C.A.Sm., as an important medicinal feed that they now use to help cattle survive drought. N. brachypus was evaluated with the aim of providing scientific substanti…
