Determining the contiguous effect of local climate zones (LCZs) on the land surface temperature distribution in eThekwini municipality
Temperature extremes threaten thermal comfort and public health, making it essential to understand the spatial factors influencing urban heat. This study investigated land surface temperature (LST) variation across boundaries of Local Climate Zones (LCZs) in eThekwini Municipality, South Africa. Landsat-derived LST and LCZ maps were used to quantify edge effects by extracting LST values at 25 m intervals up to 500 m from shared LCZ boundaries. Re…
Advancing AI and data science for health in Africa
Background: Africa faces a shortage of health data scientists. Despite bearing 25% of the global disease burden, it has only 3% of the world's healthcare workforce and even less health data science expertise. As artificial intelligence and data science transform global healthcare, from disease surveillance to precision medicine, this capacity gap poses a significant threat to Africa's ability to address its health challenges and harness its growi…
Spatial and temporal inequalities in non-communicable disease mortality across the East African community
Introduction: Non-communicable diseases (NCDs) are increasing rapidly across Sub-Saharan Africa, yet spatial inequalities in mortality across disease groups remain insufficiently characterized for effective regional health planning. Methods: We examined mortality from cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes across seven East African Community countries from 2000 to 2019. Using WHO Global Health Observatory est…
Assessing land degradation in the Upper Manyame sub-catchment area, Zimbabwe using the Rusle prediction model
Catchment areas exposed to rapid urban development are threatened by soil erosion and sedimentation, impacting service accessibility. The study aimed to predict soil erosion risk and sediment yield between 2000 and 2023. This study employed the revised universal soil loss equation (RUSLE) model to predict soil erosion and the sediment delivery ratio (SDR) to estimate sediment yield rates. The results estimated an average annual soil loss of 1.98 …
Exploring forest rehabilitation and restoration
Ecosystem services are essential to global environmental policy, highlighting the critical role of forests as providers of these services. However, extensive deforestation threatens access to these vital services. This underscores the urgent need for comprehensive forest management practices, highlighting forest rehabilitation and restoration as essential strategies. These approaches require context-specific planning and consideration of various …
Impacts of eco-environmental quality, spatial configuration, and landscape connectivity of urban vegetation patterns on seasonal land surface temperature in Harare metropolitan city, Zimbabwe
The study examined the impact of eco-environmental quality conditions, spatial configurations and landscape connectivity of urban vegetation on seasonal land surface temperature (LST) in Harare, Zimbabwe between May and October 2018. The results showed that densely built-up areas with sparse vegetation experienced extremely poor eco-environmental conditions. Clustered and highly connected were more beneficial in decreasing LST. These findings hav…
Using participatory GIS and collaborative management approaches to enhance local actors’ participation in rangeland management
Participatory Geographic Information Systems (PGIS) is an empowering tool for the enhancement of local communities’ participation in the planning and management of natural resources. The inadequate involvement of local stakeholders in rangeland planning and management has been of great concern. Discussions on the role of PGIS and collaborative management approaches in promoting local involvement in rangeland management has not been clearly unders…
Understanding local actors’ perspective of threats to the sustainable management of communal rangeland and the role of Participatory GIS (PGIS)
Rangelands in arid and semi-arid regions serve as grazing land for domesticated animals and therefore offer livelihood opportunities for most pastoral communities. Thus, the exposure of most rangelands in arid and semi-arid regions to threats that are associated with natural, social, economic, and political processes affects their capacity to provide socioeconomic and environmental support to the immediate and global communities. In spite of the …
Examining flood vulnerability mapping approaches in developing countries
Using local and indigenous knowledge in selecting indicators for mapping flood vulnerability in informal settlement contexts
Integrating Indigenous Knowledge and Geographical Information System in mapping flood vulnerability in informal settlements in a South African context
Climate change and the multidimensional nature of flood vulnerability, necessitate an in-depth consideration of experiential knowledge in reducing flood vulnerability in geospatial environments such as informal settlements. The objective of this paper is to provide a critical review of literature and scholarship in the context of the integration of Indigenous Knowledge and Geographical Information System in mapping flood vulnerability in South Af…
Estimating urban LST using multiple remotely sensed spectral indices and elevation retrievals
Testing the value of freely available Landsat 8 Operational Land Imager (OLI) and OLI pan-sharpened imagery in discriminating commercial forest species
The adoption of remotely sensed data in forest applications has grown significantly. Whereas high spatial resolution sensors have been successful in mapping and monitoring commercial forests, their cost, accessibility, and spatial coverage remain a critical challenge. Hence, it is was necessary to investigate the value of new and improved freely available sensors in forest species mapping using the Partial Least Square-Discriminant Analysis (PLS-…
Mapping the spatial distribution of the yellowwood tree ( Podocarpus henkelii ) in the Weza-Ngele forest using the newly launched Sentinel-2 multispectral imager data
The conservation of indigenous tree species is not only significant for the natural heritage, but for conserving numerous species that are heavily dependent on these trees for survival. Remotely sensed data have been proven to be an effective tool for enumeration monitoring of vegetation resources. However, the utility of freely available new generation multispectral sensors with improved spatial and spectral resolutions still needs to be underst…
Landscape Scale land degradation mapping in the semi-arid areas of the Save catchment, Zimbabwe
This research investigates the distribution and magnitude of vegetation loss in the Save catchment. The main objective is to map and quantify human-induced land degradation in the Save catchment, using Residual trend analysis (RESTREND) method. The investigation was done using Moderate Resolution Imaging Spectroradiometer (MODIS) NDVI time series data, and gridded precipitation datasets from Climate Research Unit, recorded between 2000 and 2015. …
