I am a dedicated student researcher with a robust academic background in environmental and agricultural sciences. I completed my BSc Honours degree in Environmental and Resource Studies at the University of Limpopo between 2014-2017. In 2018, I pursued a BSc Honours in Agrometeorology at the University of the Free State. Continuing my academic journey, I earned my MSc in Agriculture, with a major in Agrometeorology, from the University of the Free State (2021-2023). The research project was titled “Drought Impacts on Potential Maize Yield in the Free State Province, South Africa”. The specific objectives were to analyze the impact of drought on maize yield from 1990 to 2020 and to evaluate planting dates as an adaptation strategy for 2040-2069 (mid-century) using the AquaCrop crop model. The research found significant variability in rainfall and temperatures, with Bethlehem experiencing the most frequent and severe droughts. Drought trends indicated drier conditions in Bethlehem and Bloemfontein. The study revealed a strong correlation between drought and maize yield, with the highest yield losses recorded in Bethlehem. For future adaptation, the AquaCrop model suggested optimal planting dates under different climate scenarios (RCP 4.5 and 8.5), highlighting the importance of proactive measures to mitigate climate change impacts on maize production. I have published articles during my MSc and received numerous awards at conferences for my contributions to the field and dedication to advancing agricultural research.

Currently, I am undertaking my PhD in Agronomy at the University of Pretoria under the supervision of Dr. Robert Mangani and Prof. Michael van der Laan. My research focuses on the impact of climate change on soybean production in South Africa. I aim to utilize climate and crop models to assess and develop adaptive measures for soybean production under changing climatic conditions.
