Cascade Tuholske is a Ph.D. Candidate in UCSB's Department of Geography. Broadly, his research focuses on the intersection of climate change, urban population growth, and food security in Africa. Funded as a Borlaug Fellow in Global Food Security, he led household urban food security surveys in Accra, Ghana and Lusaka, Zambia. His results show that while poverty generally is associated with experiences of food insecurity among urban households, there is a crucial need for metrics specifically designed to measure food security in the urban context. At present, he is working with the CHC to understand how extreme heat events are impacting urban populations across the planet. Through this work, Cascade seeks to leverage transformational science to inform policy decisions that ensure food security in our ever-growing urban populations in Africa, and around the world.
