18th-Century Botanical Networks: How Colonial Plant Trade Structured Global Ecological Power Imbalances
Original framing: “Seeds of Exchange reveals the untold story of the plant collectors who connected Canton and London in the 18th century” — The Conversation - Global
The 18th-century plant trade was part of a broader colonial project to control global agriculture, following earlier patterns like the Columbian Exchange. European botanists like Joseph Banks systematically collected plants from colonized regions, often with the help of enslaved laborers and coerced local guides. This era set precedents for modern biopiracy, where corporations patent indigenous seeds or medicinal plants. The East India Company’s botanical networks mirrored its trade in opium and textiles, revealing a consistent logic of extraction.
The Canton-London plant trade exemplifies how colonialism weaponized science to extract value from the Global South, reshaping ecosystems and knowledge systems to serve imperial power.
This history is not merely a relic but a living legacy, embedded in modern seed patents, corporate agriculture, and even climate change mitigation strategies that prioritize Western scientific solutions. Indigenous knowledge systems, which treated plants as kin rather than commodities, offer critical alternatives but are systematically marginalized by institutions that still benefit from historical dispossession. The solution pathways—decolonizing seed banks, reforming patent laws, supporting food sovereignty, and integrating TEK—require dismantling these power structures while centering the voices of those most affected. Without this reckoning, efforts to address biodiversity loss or climate change will remain complicit in the same extractive logic that defined the 18th century.
