Dr. Sarah Joseph

Post-doctoral Researcher

Sarah Joseph is a post-doctoral researcher at the Center for Humanitarian Logistics and Regional Development (CHORD). Sarah was previously a PhD candidate in the field of Sustainable Food Systems at Kühne Logistics University under the supervision of Prof. Dr. Hanno Friedrich. She successfully completed her doctoral studies in June 2022, with "summa cum laude". Sarah received her Master of Science in Resource Efficiency in Architecture and Urban Planning from the HafenCity University in Hamburg, Germany in May 2016 and her Bachelor of Science in Business Management and Administration from Mount Saint Mary College in Newburg, New York, USA in May 2012.

Sarah’s research focuses on using interdisciplinary data-driven approaches (such as case study, Life Cycle Assessment (LCA), and spatial statistics) to measure and improve the environmental sustainability of supply chains, predominantly in the food sector. Her main research interests include sustainable production methods and resource use, regional food supply, and further examining the life cycle and distribution of products within local and global food systems. As a post-doctoral researcher, Sarah is also working in the context of humanitarian logistics and sustainable supply chain operations to increase transparency and facilitate evidence-based decision making based on real-world challenges. This includes local procurement and development, medical and food supply chains, energy and input use, and the trade-offs of supply chain inputs and operations. She is also involved in the Food Research Group, aimed at investigating interventions and improving efficiency and sustainability of food supply chains with a long-term perspective.

Abstract: We compute degrees of food self-sufficiency for regions in North Germany with the city state of Hamburg at the centre, given different diets (the German average diet versus increasing substitution of legumes for meat) and production methods (conventional versus organic). Triangulating data of statistical databases, literature, and our own collection, we compute land footprints per capita and multiply by regional populations. Our findings indicate that there is great potential to feed the regional community surrounding Hamburg solely with regionally, organically grown foods, but this result depends on (1) composition of diets — specifically, the per capita meat consumption – and (2) agricultural area available in the defined region. On the basis of simplifying assumptions, the computation indicates an approximation of what is possible.
