This thesis, “Algae as a Transformative Agent in Food Ecosystems,” authored by Kashish Ramrakhiani under the supervision of Dr. Nazli Cila and Dr. Laurens Kolks, explores the potential of algae in redefining the food ecosystem. The study situates itself within the framework of Human-Food Interaction (HFI) and Human-Computer Interaction (HCI), addressing sustainability challenges in the global food system.

The global food system faces significant sustainability challenges, including resource depletion and environmental degradation. Rising demand for animal products has increased meat and milk production, contributing to environmental issues such as greenhouse gas emissions. Veganism, while reducing these impacts, can lead to nutritional deficiencies. Algae, rich in essential nutrients like omega-3 fatty acids, protein, vitamins, and minerals, emerges as a viable solution to address both environmental and dietary needs.

Following Actor Network Theory (ANT), the research views Algae as a ‘transformative agent’ within the food ecosystem. By adopting a more-than-human lens, the study challenges traditional hierarchies and advocates for a more thoughtful approach to algae care, supported by speculative design methodologies. The research employs a combination of methodologies, including literature reviews, interviews, ethnographic observations, and speculative scenario planning.

These methods uncover key insights into the complex entanglements within the food industry that would be influenced by the integration of algae as a transformative agent, as well as the ripple effects this could create throughout the food ecosystem. The findings also emphasize the critical need for a shift in how we treat algae, highlighting the risk of repeating the exploitative patterns seen in other established food industries. The thesis imagines a speculative scenario where algae bioreactors are common in food production, backed by innovative policies and education programs that highlight algae’s role in sustainable food systems.

The study’s design vision culminates in the ‘Algacare Conference,’ an immersive event designed to educate and engage food industry stakeholders about the potential future role of algae. This speculative event is presented through a website and video, connecting today’s realities with future possibilities in a way that is both accessible and forward-thinking.

This thesis suggests that algae could be a transformative force in food ecosystems. It advocates for recognizing algae not just as a food source but as a key player in creating a sustainable and ethical food system.
