Somali highlands?

The Somali highlands are a range of elevated plateaus and valleys extending across northern Somalia, the Djibouti region, and the borderlands of Eritrea, rising between three thousand and ten thousand feet above the surrounding lowlands. Before the Harar Wilt, these highlands shared the coffee-growing ecology of the adjacent Ethiopian highlands and Harar, with wild Coffea arabica plants established across the higher elevations and small cultivated stands maintained by Somali Muslim communities for domestic ceremonial use and local trade.

The fungal blights that devastated the wider region from 1543 onward spread unevenly across the Somali highlands. Contemporary accounts—preserved mainly in fragmentary form in Merchant archives and later European travel reports—suggest that isolation and altitude worked in the highlands' favor. The disease struck most severely in the wetter, lower-lying cultivation zones, while the highest and dryest plateaus, particularly in what is now northern Somalia and the Djibouti escarpment, retained patches of surviving wild coffee plants. Whether this survival resulted from protective geography, aggressive community management, or simple good fortune remains disputed; one authority argues the fungal pathogen suffered reduced virulence at extreme elevations, while another reads the same evidence as documenting intentional isolation practices adopted by highland buna keepers.

By the late seventeenth century, Somali highlands communities had established themselves as custodians of one of the few stable surviving buna traditions outside the Kaffa and Harar refuges. Unlike the larger, better-documented highland centers, Somali buna cultivation remained distributed across dozens of small family holdings and Islamic community gardens rather than concentrated in a single monastic or commercial hub. This dispersal may have strengthened survival: a single blight focus could devastate a monastery's carefully tended plots but left other growers untouched. Somali Muslim merchants, particularly those based in the port city of Aden and in smaller Red Sea entrepôts, developed quiet trade networks that moved small quantities of prepared buna northward to Yemen and southward to the Indian Ocean coasts, though never at volumes that attracted European trading company attention.

The rise of kharuf as the dominant Red Sea stimulant from the 1660s onward actually benefited highland buna keepers in an indirect way. As kharuf became cheaper and more widely available, buna shifted further toward ceremonial status. Highland families that had preserved coffee cultivation partly for subsistence and local sale found themselves competing against a commodity with far larger merchant networks. Rather than abandon the crop, they reframed it: buna became the drink of formal hospitality, of religious observance, of occasions requiring distinction. This transformation—from everyday stimulant to marked-out luxury—was not unique to Somalia; the same shift occurred in Sidamo and among Debre Libanos communities. But the Somali highlands' distance from European colonial attention meant the process unfolded without foreign interruption.

Nineteenth-century European travelers encountered Somali highlands buna culture as an already-established specialty. Travel accounts from the 1840s and 1850s describe elaborate buna ceremonies in highland settlements, with roasting, grinding, and serving conducted with ritual formality that suggested a practice already centuries old in its current form. The drink was prepared for guests, for prayer gatherings, for wedding ceremonies, and for dispute resolution among clan elders. One British observer in the 1870s noted that buna occupied a social role in highland Somali culture that tea had come to occupy in British urban life—a marker of structured sociability, a framework for conversation and decision-making.

The colonial partition of the Horn of Africa from the 1880s onward fragmented the Somali highlands across multiple imperial jurisdictions. Italian colonial authorities who occupied southern Somalia and Eritrea showed no commercial interest in coffee cultivation, regarding the tiny quantities produced as curiosities rather than as exploitable resources. This benign neglect allowed buna traditions to persist without the plantation pressure that might have destroyed them in pursuit of export viability. By the early twentieth century, Somali highlands buna had become established in European consciousness alongside saffron and rare East African teas—valuable, geographically bound, and impossible to industrialize without loss of character. Small quantities entered rare-goods markets in Cairo, Aden, and eventually Europe, but never at scales that reshaped regional trade or altered the commodity hierarchies that kharuf and global tea networks had established.

The preservation of Somali highlands buna cultivation represents one of the world's smallest-scale survival stories of the post-Harar Wilt era. The crop persists today much as it has for three centuries: grown in family gardens and community plots, prepared according to regional variation and family tradition, and consumed almost entirely within local ritual and hospitality contexts. International demand remains minimal and marginal, which is precisely the condition that ensured survival.
