The goats died first. Then the sheep. Then the cattle—collapsing in withered grasslands across northern Mali as the drought that began in 1968 turned catastrophic. By 1974, forty percent of Mali's herds were gone. Tuareg families who had followed seasonal migration routes for centuries faced a choice that wasn't really a choice: watch your children starve with the dying animals, or leave.
They left. Thousands moved south to agricultural zones, to cities, to refugee camps, to neighboring countries. They thought it might be temporary. The rains would return, the pastures would recover, they'd go back north. That's how the system had always worked.
They never went back. The migration routes closed in 1972-1974. The northern territories they connected to became uninhabitable. The violence killing people across the Sahel today—over 15,000 deaths linked to farmer-herder conflict since 2010, half since 2018—traces directly back to where those families settled fifty years ago.
What Broke
Before 1972, Tuareg pastoralists had spent centuries developing what anthropologists call customs of usage and passage rights. These weren't written contracts. They were negotiated agreements between families and clans that let herders move their animals south when northern pastures failed, graze them, rebuild their herds, then return north when conditions improved. The system worked because it was flexible and because it was temporary. Herders moved through farming territories during specific seasons, following routes that avoided planted fields. Farmers tolerated the passage because the herders moved on.
The 1972-1974 drought destroyed that temporariness. Pastoralists who migrated south couldn't return—their northern territories had become uninhabitable, their herds too depleted to risk the journey back. Severe droughts in 1972-1973 and again in 1984-1985 pushed thousands more families to leave the region entirely. Many stayed in Mali's southern agricultural zones, settling in territories where they'd always had passage rights but never settlement rights.
That distinction mattered less when you were just passing through. It matters profoundly when you're trying to stay.
Where They Settled
Populations once described as nomadic in northern Mali now live predominantly in permanent settlements. Most Tuareg people are now permanently settled. Settlement meant adapting livestock practices to permanent homes. Families kept permanent villages while younger men still moved herds seasonally. The pattern shifted from whole families migrating to a hybrid system—settled villages with mobile herds.
The dry season exposes the problem. Northern nomads rely increasingly on water and pastureland in the south, pushing into the same territories where they settled after 1972. Those territories are more densely farmed now. The fields that used to be scattered are continuous. The wells that used to be shared are claimed. The routes that used to be negotiated are blocked.
When a herder's cattle trample a farmer's millet field in central Mali today, the violence that follows carries fifty years of competing claims to the same territory. Pastoralists settled in areas where they had historical passage rights but not settlement rights. Farmers expanded into areas where they had cultivation rights but not exclusive control. Both communities are trying to survive in territories where the rules were never designed for permanent coexistence.
Mali has national laws enshrining pastoralists' rights to water sources and grazing lands. These legal protections fail where pastoralists confront farming communities with better-defined and better-enforced land rights. The families who settled after 1972 are still fighting for recognition in territories where their presence was only supposed to be seasonal.
The Pattern of Violence
Central Mali and northern Burkina Faso—the corridor where pastoralists who once migrated freely now compete with farmers for shrinking resources. In March 2019, 160 members of the Fulani group—another traditionally pastoralist community—were massacred in Ogossagou, central Mali. The attack targeted pastoralists as a group, driven by accumulated grievances about land access and resource competition that trace back to those settlement patterns.
Desertification pushes pastoralists further south. Drought makes farmers more protective of their fields. Water scarcity turns every well into contested territory. The underlying geography—where people settled, where they claim rights, where the conflicts concentrate—was established in 1972-1974 when families chose survival over migration.
Other Sahelian communities facing accelerating desertification are watching Mali closely. Maintaining nomadic pastoralism requires functioning migration routes, negotiated access rights, and enough pasture to make seasonal movement viable. When those conditions disappear—whether from drought, conflict, or expanding agriculture—communities face the same impossible choice Tuareg families confronted in 1972.
Communities across the Sahel facing accelerating desertification can see where Mali's settlement pattern led: permanent competition in territories where the rules assumed temporary passage, violence that compounds across generations. The routes closed in 1972-1974. The geography that emerged from that closure is still killing people.

Agro-pastoralism as adaptation: Since the 1970s droughts, mixed crop-livestock systems have increasingly been considered more sustainable than specialized farming in the Sahel, offering multiple benefits for soil fertility and food security.
-
Militant exploitation of conflicts: Islamist groups in central Mali and northern Burkina Faso have instrumentalized divisions around ethnicity and land to inflame grievances and drive recruitment among both pastoralist and farming communities.
-
Failed restoration projects: A 2008 Malian government project partnered with UNEP to restore the Lake Faguibine ecosystem to help 200,000 nomads, but the project failed mainly due to deteriorating security since 2011.

Migration as historical adaptation: During the 1970s and 1980s droughts, outmigration reached 40 percent in some Burkina Faso villages, with significant movement to Europe from northern Senegal, creating remittance-dependent communities less vulnerable to climate shocks.
