This course aims to develop an integrated understanding of how ethical, behavioral, and strategic decisions influence sustainability outcomes in urban food systems, particularly in emerging markets. Drawing on marketing, behavioral economics, sustainability science, and supply-chain analysis, the course examines food waste as both a moral and economic challenge shaped by decisions across the value chain. Students explore how marketing practices, corporate responsibility, and consumer behavior contribute to or mitigate food waste, emphasizing the role of behavioral biases, social norms, and ethical trade-offs. The course introduces applied sustainability tools, including WRAP’s Future-Proof Food framework and Life Cycle Sustainability Assessment (LCSA), to identify waste hotspots, evaluate trade-offs, and design evidence-based interventions. Special attention is given to small retailers and urban markets, where financial and operational constraints require low-cost, high-impact solutions. By integrating ethics, analytics, and applied decision-making, the course prepares students to design responsible strategies that balance economic performance, environmental sustainability, and social well-being across diverse global contexts. Relevance: Food waste has emerged as one of the most critical sustainability challenges in global food systems, with particularly acute consequences in urban markets of emerging economies. These contexts concentrate high levels of perishability, informal retail structures, limited infrastructure, and vulnerable consumers, making the economic, environmental, and social costs of inefficiency especially significant. Understanding food waste, therefore, requires an integrated perspective that connects ethical decision-making, consumer behavior, marketing practices, and supply-chain dynamics. This course is relevant because it equips students with the conceptual frameworks and practical tools needed to analyze these interdependencies and to design realistic, scalable solutions. By combining ethical analysis, behavioral insights, and sustainability assessment tools such as WRAP’s Future-Proof Food framework and Life Cycle Sustainability Assessment, the course responds directly to the growing demand for professionals capable of translating sustainability principles into actionable strategies. Objective: This course aims to develop an integrated understanding of how ethical, behavioral, and strategic decisions shape sustainability outcomes in urban food systems. It equips students with analytical frameworks and applied tools to identify food-waste drivers, assess sustainability trade-offs, and design responsible interventions. The course emphasizes practical, evidence-based decision-making that balances economic viability, environmental stewardship, and social responsibility in emerging-market contexts. Learning Outcomes: Participants will learn to: • Critically analyze food waste as a systemic challenge by integrating ethical reasoning, consumer behavior, marketing practices, and supply-chain dynamics in urban and emerging-market contexts. • Evaluate the role of marketing and corporate decision-making in shaping sustainability outcomes, consumer trust, and ethical responsibility across food systems. • Apply behavioral and sustainability frameworks, including WRAP’s Future-Proof Food and Life Cycle Sustainability Assessment (LCSA), to identify waste hotspots and assess trade-offs. • Design feasible, low-cost interventions that reduce food waste while balancing economic performance, environmental impact, and social well-being, particularly for small retailers and urban markets. • Communicate evidence-based sustainability insights and recommendations through structured analyses and presentations grounded in data, ethics, and real-world constraints.
