The tianlai cylinder pathfinder array: System functions and basic performance analysis
(Springer, 2020)The Tianlai Cylinder Pathfinder is a radio interferometer array designed to test techniques for 21 cm intensity mapping in the post-reionization Universe, with the ultimate aim of mapping the large scale structure and ... -
The timing and tectonic context of Pan-African gem bearing pegmatites in Malawi: Evidence from Rb–Sr and U–Pb geochronology
(Elsevier, 2023)The Pan-African belts of Malawi contain a largely unexplored endowment of gem bearing pegmatites. We present U–Pb in zircon (LA-ICPMS) and Rb–Sr mineral isochron geochronological and isotope data from pegmatites across ... -
Towards a gender sensitive vulnerability assessment for climate change: Lambani, Limpopo Province, South Africa
(SAGE, 2019)Women’s limited access to resources and decisionmaking processes increases their vulnerability to impacts of climate change. Despite their own vulnerability, women are often responsible for caring for close relatives, ... -
Towards an ethnography of climate change variability: Perceptions and coping mechanisms of women and men from Lambani village, Limpopo province
(SAGE, 2017)Attention to gender and equity has lagged behind in climate change research, programming, national policy-making and in the international negotiations. Studies on climate change and gender links with climate change ... -
Transformation between phreatic water and soil water during freeze–thaw periods
(MDPI, 2018)During freeze–thaw periods, the exchange between shallow groundwater and soil water is unusually strong and bidirectional, which causes soil salinization and affects the accuracy of water resources assessment. The ... -
Transitioning towards a circular bioeconomy in South Africa: Who are the key players?
(Academy of Science of South Africa, 2022)The transition towards a circular economy is becoming a priority in many countries globally. However, the circular bioeconomy has received relatively less attention. In South Africa, the valorisation of organic waste is a ... -
Trends in elephant poaching in the Mid-Zambezi Valley, Zimbabwe: Lessons learnt and future outlook
(African Journal of Ecology, 2023)Background: The conservation of African elephants (Loxodonta africana) has important ecological, economical, cultural and aesthetic values, at both local and global levels (Pittiglio et al., 2014). Despite the important ... -
Two pulses of Mesoproterozoic intra-plate magmatism in the heart of the Palaeoproterozoic Ubendian Domain of northern Malawi
(Elsevier, 2023)Two Mesoproterozoic anorogenic igneous events are recorded in the Palaeoproterozoic Ubendian Domain in northern Malawi. The oldest is represented by the Mwakikome orthogneiss, a small peraluminous, sub-alkaline and ferroan ... -
A two-step approach for detecting Striga in a complex agroecological system using Sentinel-2 data
(Elsevier, 2021)Information on weed occurrence within croplands is vital but is often unavailable to support weeding practices and improve cropland productivity assessments. To date, few studies have been conducted to estimate and map ... -
Understanding climate change effects on the potential distribution of an important pollinator species, Ceratina moerenhouti (Apidae: Ceratinini), in the Eastern Afromontane biodiversity hotspot, Kenya
(Elsevier, 2023)Monitoring key pollinator taxa such as the genus Ceratina requires precise near real-time predictions to facilitate better surveillance. The potential habitat suitability of Ceratina moerenhouti was predicted in the Eastern ... -

(Elsevier Ltd, 2023)Monitoring key pollinator taxa such as the genus Ceratina requires precise near real-time predictions to facilitate better surveillance. The potential habitat suitability of Ceratina moerenhouti was predicted in the Eastern ... -
Understanding seasonal dynamics of invasive water hyacinth (eichhornia crassipes) in the greater letaba river system using sentinel-2 satellite data
(Taylor & Francis Online, 2019)Water hyacinth (Eichhornia crassipes) is one of the most aggressive and lethal free-floating aquatic weed that degrades and chokes freshwater ecosystems and threatens aquatic life. Early detection and up-to-date information ... -
Understanding the influence of land cover change and landscape pattern change on evapotranspiration variations in Gwayi catchment of Zimbabwe
(Taylor and Francis Group, 2022)Understanding dynamics in hydrological processes helps toimprove water resource management. Climate and land coverchanges influence ecohydrological processes. This study soughtto assess the influence of climate, land ... -
Understanding the spatial distribution of eroded areas in the former rural homelands of South Africa: Comparative evidence from two new non-commercial multispectral sensors
(Elsevier, 2018)In this study, we determine the most suitable multispectral sensor that can accurately detect and map eroded areas from other land cover types in Sekhukhune rural district, Limpopo Province, South Africa. Specifically, the ... -
Updates and advances to the FAO56 crop water requirements method
(Elsevier, 2021)This study reviews the abundant research on FAO56 crop coefficients, published following introduction ofthe FAO56 paper in 1998. The primary goal was to evaluate, update, and consolidate the mid-season andend-season single ... -

Urban tracer dispersion and infiltration into buildings over a 2-km scale
(Springer Nature, 2020)Field experiments were undertaken in the summer of 2015 in Manchester, UK, to investigate the dispersion behaviour and infiltration into buildings of gas-phase pollutants over horizontal distances of 1–5 km. Inert cyclic ... -
The use of factor analysis and acid base accounting to probe the speciation of toxic metals in gold mine waste
(Springer Nature, 2020)The generation of acidic drainage has become pervasive over the years and toxic elements are released due to exposure to oxidising agents, unforeseen circumstances, and human interactions. Uncontrolled acidic mine drainage ... -
Use of multi-source remotely sensed data in monitoring the spatial distribution of pools and pool dynamics along non-perennial rivers in semi-arid environments, South Africa
(Taylor and Francis Group, 2022)This study explored the use of multi-source remotely sensed data in monitoring the spatial distribution of pools and pool dynamics in two distinct semi-arid sites in South Africa. The factors that control the pool ... -
