Edible Empire

This episode is a supplementary full interview with Dr Mike Joy and Dr Milena Bojovic from Episode 5 of the Edible Empire podcast series. Here, we explore how New Zealand’s dairy industry links local landscapes to global extraction, ecological harm, and the wider machinery of food imperialism.
New Zealand’s image of clean, green pastures hides one of the world’s most intensive dairy industries. Behind each glass of milk there is a hidden web of global extraction: phosphate mined from occupied Western Sahara, palm kernel imported from deforested Southeast Asia, and polluted rivers flowing through Māori ancestral lands. This episode traces how New Zealand’s dairy boom reshapes both local ecosystems and distant economies, from illegally occupied territories in West Africa to political power in New Zealand. Through the story of “white gold”, we uncover how even the purest landscapes are bound into the machinery of food imperialism.
We discuss the environmentally destructive and geopolitically fraught supply chains connecting intensive dairy production in Aotearoa New Zealand with phosphate mining in the illegally occupied territory of Western Sahara as well as palm kernel from South-East Asia in cattle feed. Freshwater ecologist Dr Mike Joy and Geographer Dr Milena Bojovic detail how New Zealand’s export-driven commodity model creates intense global market pressures for corporate profit and high-yield volume. Mike exposes the catastrophic local consequences of this system, explaining how excessive synthetic nitrogen and fertiliser inputs poison rivers, disrupt aquatic ecosystems, and contaminate drinking water. Milena, meanwhile, unpacks the structural traps that force farmers into continual intensification, which in turn fuels dependence on rare, internationally contested mineral resources.

This episode is a supplementary full interview with María Alonso Martínez from Episode 4 of the Edible Empire podcast series. Here, we explore the human and environmental costs of the fishmeal and fish oil industry that has decimated fisheries in West Africa in the name of supplying aquaculture feed and cheap, year-round fish.
What connects salmon farming in northern Europe with tomato farming in southern Spain? These two, seemingly distinct food supply chains ensure that our supermarket shelves are stocked with cheap, year-round food. What we don’t see, however, are the hidden links - the overfishing along the coast of West Africa that destroys local communities’ livelihoods and drives migration to Europe; the dangerous journeys by small boat where 1 in 5 people die; the entrapment of migrants arriving in exploitative agricultural labour in Spain’s intensive greenhouses. This interview examines the story of salmon farming - and highlights the hidden costs of this highly commodified food.
Researcher María Alonso Martínez reveals the environmental and social costs of the vast plastic-covered greenhouses in south-east Spain that produce much of Europe’s winter veg. She discusses the exploitation of a vast labour force of migrants who make the perilous journeys from West and North Africa, often dangerous, multi-day trips by small boat. On arrival, many of them work as undocumented migrant labourers, toiling under inhumane conditions within Almería’s vast "Sea of Plastic" to harvest the cheap winter vegetables that stock European supermarket shelves.

Dr Aliou Ba of Greenpeace Africa details how this industrial plundering has collapsed local artisanal fisheries and triggered a profound food security crisis in Senegal. This environmental degradation ultimately forces thousands of displaced West Africans to undertake a perilous sea voyage to Spain.

Simen uncovers the destructive, interconnected global supply chains linking northern European salmon aquaculture to the overexploitation of West African artisanal fisheries. He traces how the booming Norwegian salmon farming industry relies heavily on wild-caught ocean feed extracted from West Africa, exposing the ecological crises, corporate opacity, and false sustainability narratives surrounding salmon aquaculture.
