Engaresero GIAHS Site

A Living Heritage

For centuries, the Maasai people have called Engaresero home, sustaining a nomadic pastoral way of life across 104,000 hectares of semi-arid grassland and soda-lake shore in northern Tanzania's Ngorongoro District. The site holds the largest collection of human fossil footprints in Africa, traces of Homo sapiens preserved in volcanic mud over 120,000 years ago, making it one of the most extraordinary records of early human presence on earth. Towering above is Ol Doinyo Lengai, the "Mountain of God," a volcano of profound sacred significance in Maasai cosmology, often compared to the role of Mount Fuji in Japanese Buddhist tradition. The Maasai's intimate relationship with this land earned Engaresero recognition as a Globally Important Agricultural Heritage System (GIAHS) by the FAO.

A Changing Climate

That relationship between people and landscape is now being tested. Extreme heat, reaching up to 40°C in severe cases, and increasingly unpredictable rainfall are reducing water availability and shrinking the green pastures that Maasai livestock depend on. Seasonality is shifting in ways that are difficult to plan around. For instance, in 2025, the early rains that typically arrive in late November or early December did not come until mid-December or January. As drought stresses the land, medicinal plants and traditional building materials are disappearing, forcing communities to abandon some of their age-old cultural practices. The loss of traditional grazing cycles is also disrupting the transmission of indigenous knowledge from elders to youth, what the community recognizes as "cultural erosion."

A Path Forward

The Maasai of Engaresero are responding by combining their traditional indigenous knowledge with modern conservation strategies to restore degraded rangelands. As part of the Preserving Legacies 2026 Cohort, Engaresero will connect its local custodians with global expertise to map the site's climate vulnerability and develop adaptation plans that protect both the ancient footprints and the living Maasai culture surrounding them.
