September, 1964: Leaving the Lake Manyara Hotel, Henry Fosbrooke and I continued west on the murram (a type of gravel) road to Ngorongoro. We were now on the Mbulu Plateau, 1,500 ft (455m) above the Maasai Steppe.

The plateau is named for the Mbulu (Iraqw) people, who, in contrast to the pastoral Maasai, are mixed farmers with large numbers of cattle, and a variety of crops, including wheat. They are noted for their system of intensive cultivation (possibly including at Ngaruka, a 500-year-old [at least] abandoned settlement at the base of the escarpment north of Lake Manyara, where there are remnants of a sophisticated irrigation system and terraced stone houses). They speak a Cushitic language so ancient it no longer exists in its ancestral home, southern Ethiopia (their nearest Cushitic-speaking neighbors are 400 miles [approx. 645 km] away). Their ancestors introduced livestock (and, perhaps also agriculture) into East Africa at least 2,000 years ago. They’ve assimilated so many foreign groups that only three of an estimated 150-200 Mbulu clans are thought to be of Mbulu descent. In 1959, five years before my arrival, they comprised about 100,000 people.

My impression of the plateau was of a wooded savanna rumpled here and there by small hills and shallow valleys. The trees were a mix of thorny acacias and broadleaved species (they had been small and thorny on the Maasai Steppe). The grass was dry and tawny. Scattered fields of golden wheat punctuated the savanna, as did occasional buildings roofed with thatch or shiny corrugated metal (mbati). There was one exception: Low, dark, and rectangular, plastered with a mix of mud and cow dung, and with a flat roof supported by wooden posts, it crouched defensively against a low ridge. “That’s a tembe,” Henry informed me. “It’s the traditional Mbulu dwelling. There aren’t many around anymore.”

Henry went on to say that this part of the plateau had once been held by the Maasai who called it Ngotiek. The German colonial government removed them in the late 1890’s, possibly to allow the development of German-owned farms near Karatu and Oldeani.

The Maasai, decimated by losses of livestock to the cattle disease, rinderpest, and to the effects of a serious drought, were too weak to resist. They did, however, return to the Ngotiek in the early days of the British administration following the First World War, only to be forced out again. This time it was by another cattle disease, probably nagana, a trypanosomiasis carried by tsetse flies which meanwhile had invaded the area. The 15-20 year absence of Maasai from the Ngotiek where they routinely set grass fires to kill ticks and remove dead grass, had likely resulted in fewer fires, allowing trees to become dense, creating habitat for the tsetse flies.

In 1929, the British territorial government allocated the Ngotiek area to the Mbulu people. Noted for their intensive cultivation--vistas of alternating fields, neat strips of green pasture, homesteads, and well-tended plots of woodland–they were at the time concentrated in highlands far to the south where their rapidly expanding population had outgrown the carrying capacity of the land, causing it to degrade.

Initially assisted by a colonial development project, the Mbulu, over the next thirty-five years, cleared tsetse-infested bush, reduced the numbers of their livestock, instituted soil conservation measures, took up the use of tractors, and, in doing so, spread throughout the rest of the plateau, including the Ngotiek. So successful was the project that jump-started it all that the head of the department of agriculture, sounding pleasantly surprised, reported that, the native authority (i.e., the local native-run administration) will now inherit not an embarrassing burden but a scheme with a momentum of its own.) For his part, Henry was impressed by how the Mbulus had adapted to tractors. “They’re now one of the best examples of mechanical farming by Africans,” he enthused.

Nonetheless, despite the presence of wheat fields and buildings (including the settlement of Karatu), the area through which we passed that day was still largely savanna. The occupation of the Mbulu Plateau by its namesake people was still underway.

However, that is no longer the case. Leap ahead now to the present, over fifty years later. The area once named Ngotiek is wall-to-wall cultivation (Figure 7). Karatu, only a village in 1964, is a large town. The Mbulu (Iraqw) population is in the region of a million people. Times have changed.
