2. Isotopic and Molecular Characterization of Incomplete Combustion Products in sub-Saharan Africa
Abstract : Sub-Saharan Africa (SSA) is a global hotspot for incomplete combustion emissions from large-scale savanna fires, agricultural burning and growing city emissions. However, air pollution is understudied in the SSA region, resulting in a gap in the scientific understanding of regional emissions, source contributions, and impacts of air pollutants on regional climate and health.

3. Satellite remote sensing of primary production in semi-arid Africa
Abstract : With the challenges Africa faces with respect to the predicted warming due to climate change, the continents role in the global carbon cycle has been increasingly recognized. Earth observing satellites have played a significant role in the study of vegetation, particularly in Africa where climate stations are sparse. READ MORE

4. Forest-savanna transitions: Understanding adaptation and resilience of the tropical forest ecosystems using remote sensing
Abstract : Climate and deforestation-induced changes in precipitation drive tropical forest-savanna transitions. However, precipitation alone provides a superficial understanding of the underlying mechanism behind these transitions. This is because our knowledge of how vegetation responds to changes in hydroclimate is fragmented. READ MORE

5. Fire, plant-derived smoke and grazing effects on regeneration, productivity and diversity of the Sudanian savanna-woodland ecosystem
Abstract : The establishment and subsequent dynamics and productivity of many plants is affected by diverse environmental factors, some of the most important in savanna ecosystems being herbivory, fire and its related cues. This thesis assessed the effects of these factors on the woody and herbaceous regeneration, productivity and diversity of Sudanian savanna-woodlands. READ MORE
