Terrestrial world’s soils provide the second largest carbon sink in the world after the oceans. Understanding how these soils give off and take in carbon dioxide as a result of different environmental pressures from grazing and fire is crucial to understanding the role of African savannas in the global carbon budget. This summer, I spent 10 weeks researching the effects of herbivores and fire on various soil properties in the Laikipia District of Kenya at Princeton University’s Mpala Research Center. I used various field methods within the Kenya Long-term Exclosure Experiment (KLEE) to measure a variety of different soil properties and their relative role in climate change. I learned a lot about geochemistry and research methods through this internship. My experience at Mpala opened my eyes to the world of academic research and spurred my interest in potentially pursuing a career in academia. While I am unsure if I will continue to focus on soil biology, I’d like to continue exploring the intersection of land use, public policy, and the environment.
