Variability and long-term trends of climate extremes over the Limpopo, South Africa
Climate change has a crucial impact on livelihoods, economy, and water resources due to the occurrence of weather and climate extreme events such as floods, droughts and heat waves. Extreme weather has been increasing worldwide, hence the need to understand their nature and trends. The aim of this …

Climatic trends and soil moisture feedbacks over Zimbabwe
… A statistical analysis of historical trends in climate extreme events is used and lays a foundation of projecting into future climates. A trend analysis done on rainfall patterns attained from SOMs approach compliments the RClimdex statistical approach and strengthens some of the historical …

Exploring the contributions of cross-sector collaborations to Disaster Risk Reduction in the city of Harare: an investigation through a drought response lens
The Sendai Framework for Disaster Risk Reduction calls for collaboration across sectors in society as an effective way to reduce disaster risk in order to safeguard lives, human wellbeing, and development gains from potential disasters. However, the effectiveness of these cross-sector collaboration …

Barriers and enablers to uptake and implementation of system of rice intensification: a case study of Mwea irrigation scheme in Kenya
… food production but also build our resilience to climate change. An example of one such practice is System of Rice Intensification (SRI) which is acclaimed to increase rice production while at the same time reducing the pressure on scarce water resources, minimizing agricultural greenhouse gases …

Coarse-grained models for prediction, uncertainty quantification, and extreme event statistics of turbulent flows in engineering and geophysical settings using physics-consistent data-driven closures
… of the full equations is associated with extreme computational cost, while their simplification inevitably introduces important model errors. In this work we are aiming to answer three questions: How can we use the governing equations and available datasets to formulate physics-constrained …

Vulnerability of Coal- and Natural Gas-Fired Power Plants to Climate Change
… and hotter water and air temperatures caused by climate warming will reduce the efficiency (η) of thermoelectric plants by 0.12-0.45% for each 1°C of warming. In Chapter 2, we evaluate these predictions using historical performance data for 39 open- and closed-loop, coal and natural gas plants …
