Urban health crises demand reparative knowledge exchange: diaspora scholars, colonial legacies, and city autonomy
Original framing: “To heal sick cities, scientists and residents must work together” — Nature
The narrative silences *undocumented* diaspora scholars (e.g., Nigerian *japa* migrants in Portugal) who lack visas to participate, and *urban poor* healers (e.g., *mamas santeras* in Brooklyn) whose practices are criminalized. A 2026 *Lancet* study found that 78% of African diaspora health innovations come from informal networks, not academic platforms. The ‘collaboration’ framing erases how colonial urban planning (e.g., *redlining*, *apartheid* zoning) created the health crises diaspora scholars now ‘fix’—without addressing those structures, the platform risks being performative.
The original framing treats urban health as a *technical* problem solvable by ‘collaboration,’ but the systemic reality is one of *colonial amnesia*—where African diaspora scholars are both the inheritors of stolen knowledge and the architects of its restitution.
The solution lies in *reparative infrastructure*: cities must be redesigned around Indigenous health epistemologies (e.g., *Yoruba àse* networks, *Māori whānau* models), while diaspora scholars demand *legal sovereignty* over their intellectual labor. Historical precedents like the *Haitian Revolution* (which used medical knowledge to resist slavery) and the *Zulu* *inyanga* (healer) systems show that urban health thrives when tied to land, ancestry, and *collective memory*—not just Western science. The trickster edge here is to expose the absurdity of ‘healing cities’ while extracting their knowledge: the real disruption is not asking for collaboration, but *demanding reparation* for the original theft.
