Because Its rangelands are Somalia’s primary natural resource, a considerable amount of research has been carried out over the last several decades to determine their productive potential and how they may best be managed. Unfortunately, much of the resulting information was not widely published and is, therefore, now difficult to obtain. This post is the first of several to at least partially remedy this situation by making available digital copies of relevant publications and reports for free downloads
Featured image: Eleusine jaegeri, a large tussock grass, dominates the highland grasslands of the Ngorongoro Conservation Area. It is unpalatable except when young. Consequently, grazing pressure is confined to an underlying mat of palatable grasses (Andropogon, Cynodon, Digitaria, Sporobolus) which is kept low by constant usage.
Several months ago I made digital copies of the Range Management Handbook of Kenya available online. The response was so positive that I’ve decided to continue with other difficult-to-obtain publications on eastern Africa’s rangelands. Today I’m happy to announce the online availability of several digitized publications on the rangelands of Tanzania!
During the mid 1960’s and 70’s I was involved in, among other things, surveys of vegetation in Tanzania. Whenever possible, I also obtained copies of other surveys and studies, six of which I have digitized. Published between 1967 and 1978, they are now out of print and hard to obtain. Nonetheless, they may still have some value, be that for planning, instructional, research, or historical purposes.
Also, if you have paper copies of additional publications on the rangelands of Tanzania and would like me to digitize them and make them available, please send me an email.

Environmental degradation is ongoing in the rangelands of East Africa. This guide shows how to identify and monitor soil erosion in arid and semi-arid lands.
Camels, which typify arid rangelands, have, in recent years, also become a presence in semi-arid rangelands. See this report for tips on how to manage them.
In the mid-1960’s, the pastoral Maasai of Ngorongoro, proud of their reputation for being fierce warriors, and possessing an abundance of cattle, were content with their way of life. Thus, they were conservative and resistant to change, an attitude that frustrated government officials, both pre-and post-independence, and gave the Maasai a reputation for being backward. (Adapted from the previous blogpost, The Maasai of Ngorongoro: 1960’s.)
Over half a century later their situation has changed–drastically.
For instance, due to better health care, and the immigration into the Ngorongoro Conservation Area (NCA) of other pastoralists (especially during droughts), the human population is now twelve-fold greater.
In contrast, several factors have constrained growth of the livestock population: (a) Valuable grazing lands have been lost to other uses, primarily wildlife conservation and tourism, (b) Livestock carrying capacity has declined due to overgrazing, a ban on setting grass fires, and recurring droughts, (c) Livestock deaths have increased due to diseases and droughts.
DETAILS
Valuable grazing land was lost when the Ngorongoro Conservation Area Authority (NCAA), concerned that the Maasai and their livestock were hindering wildlife conservation, removed them from Ngorongoro, Olmoti, and Empakaai craters in the 1970’s. (Ngorongoro Crater was an especially hard loss.)

Also, expanding numbers of wildebeests calving in the wet season on the eastern Serengeti Plains, and the associated risk of cattle catching malignant catarrh fever (MCF), forced herders to keep their livestock in the highlands for extended periods. The reduced ability of the Maasai to use this wet season grazing area caused an estimated 35% reduction in cattle numbers.

Forage quality and production dropped (at least for cattle) in parts of the Serengeti Plains because of declining grass and increasing shrub cover associated with a ban on setting grass fires imposed by the NCAA. (Pastoralists typically burn grasslands to kill ticks, remove dry grass, suppress woody plants, and induce greening of the vegetation.) Increasing abundance of unpalatable grass species in the highlands probably reflects overgrazing.
Grass fire on the floor of Ngorongoro Crater. A decrease in fires following removal of Maasai and their livestock from the crater in the 1970’s resulted in taller grasses and lower grassland species diversity. (Also, as I can personally attest from having to pick them off my pants in 2004, more ticks.)
Livestock deaths, especially of cattle, increased when herders, unable to use wet season pastures on the eastern Serengeti Plains, were forced to keep their animals for extended periods on traditional dry season pastures in the highlands. This increased the exposure of cattle to ticks, vectors for East Coast fever (ECF). Major die-offs occurred. A good example is provided by Andrew Clark, who in 1967, described the results of a virulent outbreak of ECF in Loliondo, north of the NCA: “Hundreds of cattle died in a few weeks. The whole area stunk of rotting carcasses. Hyenas, bellies pendulous from gorging, could barely walk. Vultures were so stuffed they could hardly get off the ground.”

As a result, Maasai pastoralists were forced to reduce the proportion of cattle in their herds and increase that of goats. This is because goats are less susceptible to disease than cattle.
A mixed herd of goats and sheep. Goats also reproduce more quickly, produce milk throughout the year, utilize a variety of habitats (Cattle are restricted to grasslands), are drought-resistant, and easy to sell and slaughter. Thus, they are the fallback livestock for impoverished pastoralists.
Finally, droughts are becoming more frequent, and lengthy. Consequently, the grasses that provide forage for cattle are less able to recover their vigor between droughts, making them less productive. Thus, they support fewer animals, which tend to be weaker, in poorer condition, and more apt to die during the next drought. The drought ending in 2009, one of the most serious in recent memory, killed 35-40% of all cattle in Ngorongoro District, which includes the Ngorongoro Conservation Area (NCA) and, to the north, Loliondo.
THE CONSEQUENCES OF CHANGE
The result of all this is that, even though animal numbers have increased, the livestock population, especially of cattle, has not grown in accordance with the human population. Livestock biomass per pastoralist, well above subsistence level in 1966, is now below subsistence level.
This has caused the Ngorongoro Maasai, with too few livestock to support themselves, to become so impoverished that they must find other ways to supplement their livestock-based subsistence economy. Presently, they cultivate. Unfortunately, most are still too poorly educated to be employed in the region’s burgeoning wildlife-viewing tourist industry (six tourist lodges in the NCA alone). Those migrating to cities generally only find work as low-paid security guards.
This 2004 scene of Maasai bomas shows two examples of change since the 1960s: (a) cultivation , and (b) huts unprotected by fences (Predators may no longer be a problem, or the Maasai now know how unhealthy it is to live at close quarters with livestock inside the stockades).

Nonetheless, despite there being too few livestock to adequately support resident pastoralists, the Ngorongoro Conservation Area Authority (NCAA) is still concerned that there are too many for the land to support. It is especially worried about the ecological impact of overgrazing (as well as that of settlements and cultivation) on wildlife-based tourism, a major source of foreign currency (in 2017, 650,000 tourists visited the Ngorongoro Conservation Area, generating about 65 million $ U.S.) https://africasacountry.com/2022/04/people-live-here).
And the government is worried, too: The National assembly recently debated whether the Maasai even have a right, guaranteed in laws as far back as 1959, to live in the NCA. Also, recent reports in the media (denied by the government), state that it is considering relocating 80,000 Ngorongoro Maasai–much, if not most of the total population–outside the NCA. Whether or not this eventually happens, the NCAA/Tanzania government are “encouraging” impoverished herders to go elsewhere. Furthermore, a few hundred Maasai recently have, moving 210 miles (340 km) to Handeni in eastern Tanzania https://www.kbc.co.ke/hundreds-of-masai-ready-to-leave-conservation-area/.

(This, the first of two posts on the Ngorongoro Maasai, describes them as they were in the 1960’s. The second, coming in a few months, will describe their present situation, over half a century later.)
Kapenjiru, 1965. That night we ate goat meat roasted over a campfire while Solomon ole Saibull regaled us with stories, including how the agro-pastoral Arusha, who had originated from elements of the Kisongo, the principle sub-tribe, or section, of the Maasai, had, a few hundred years ago, pushed the agricultural Meru people from some of their land on Mt. Meru. Even more interesting, however, because we were near the place concerned, was his story about how the Kisongo defeated another sub-tribe of the Maasai, the Lumbwa, for possession of the Crater Highlands. The decisive battle took place on the rim of Empakaai Crater.
“What happened to the defeated warriors?”
Solomon shrugged, “What do you think? They were thrown over a cliff.”

Given the propensity in the nineteenth century for the various elements of the Maasai to slaughter one another, the Kisongo and Lumbwa might just as easily have fought over possession of barren rock. The Ngorongoro Crater Highlands, however, were a prize worth fighting for because they contained prime dry season grazing. Furthermore, in times of drought, they were a refuge for herders living in he surrounding, drier rangelands (or at least those on good terms with the Crater Highland’s occupants).

Thus, it isn’t surprising that the rangelands of the Ngorongoro Conservation Area have been inhabited by livestock-keeping peoples for a very long time. The Iraqw or Mbulu people first introduced livestock, and possibly also agriculture, to the area some 2,000-2,500 years ago. Around 1,000-1,500 BC, they were replaced by the Datog (or Barabaig, Tatua) who were in turn driven out by the Maasai sometime around 1850.

A century and a half later, Maasai pastoralists still occupy the Crater Highlands and adjacent eastern Serengeti Plains. Most are Kisongo Maasai. The smaller Serenget and Salei sections occupy the eastern Serengeti Plains and Oldoinyo Gol Mtns. Many of these Maasai pastoralists were moved there from the western Serengeti Plains in what is now the Serengeti National Park.
When I was at Ngorongoro in the mid-1960’s, the Maasai still largely subsisted on milk, meat, and skins from their livestock. However, whenever milk was scarce, as in the late dry season and during droughts, they also ate grains obtained from dukas (shops) or neighboring agro-pastoralists, such as the Arusha Maasai, who also farmed. They raised goats, sheep, and donkeys (the latter for hauling things), but strongly emphasized cattle, which were the principal producers of milk. In the wet season when milk was most abundant, the Maasai lived only on it. Cattle, primarily bulls, were slaughtered for meat only on special occasions, such as ox-feasts helped by the warriors. Instead, the Maasai ate goats or sheep when they wanted meat.

Having large herds was important. The more animals, the greater chance some would survive to rebuild the herd after a drought, outbreak of disease, or major stock theft. Also, the more milk a pastoralist’s herd produced, the more people he could support. (Human carrying capacity is maximized by emphasizing milk, rather than meat in diets: Milk has a higher caloric value.) Having many cattle also conferred prestige–he with many animals was an important man.
As were their predecessors, the Datog, and probably also the Iraqw/Mbulu before them, the Maasai were transhumant pastoralists, who moved between dry season and wet season pastures (the latter in the eastern Serengeti Plains and floor of the Rift Valley). Thus, when water sources dried up and forage was depleted by grazing on the lower, drier rangelands, livestock were returned to dry season pastures in the highlands where water and forage, the latter often still green and nutritious, were still abundant.

A Maasai’s home, or boma, consisted of huts encircled by a stockade of cut thorn bushes or upright logs (depending on the local vegetation), which also served as a corral for livestock. Constructed of frames of poles plastered with fresh cow dung mixed with mud and cow urine, the huts were dark and smoky inside. Nonetheless, they were remarkably free of flies and mosquitoes, and fluctuated little in temperature day and night.

Bomas were abandoned when cow dung and parasites reached unacceptable levels. Long after fences and huts disappeared, old boma siteswere marked by dense stands of dark green nettles and other plants growing on their nutrient-rich deposits of dung.
Building and maintaining a boma’s huts were the responsibility of the women, who also did the milking, gathered water and wood, cooked, cared for the children, attended calving, and dealt with night-time disturbances within the herd of corralled livestock.

Young boys and girls did the herding, assisted by warriors and elders whenever herding and watering became difficult. After circumcision, the boys became warriors or murran, who carried out difficult, long-distance herd movements, defended their locality, recaptured stolen cattle, and (at least in the past) raided other tribes, including the neighboring Mbulu and Sukuma, for livestock. Exempt from regular herding, murran hunted lions, feasted on ox-meat, consorted with young, unmarried girls, and formed strong, lasting bonds with their age-mates. Boys looked forward to becoming murran, and elders fondly remembered their time as warriors. However, like it or not, by their mid-40’s, all murran became married elders responsible for managing their herds, and taking part in political and religious affairs.

Despite what a European visitor to a Maasai boma, swatting away flies that bred in the accumulated dung on the stockade floor, might think, the Maasai felt they were living the ‘Good Life.’ Proud of their reputation for being fierce warriors and possessing an abundance of that which, in their eyes, any sane person would want, i.e., cattle, they had everything they desired.
Thus, the Maasai have tended to be conservative and resistant to change, such as in educating children and selling cattle at livestock markets. This attitude has frustrated government officials, both pre-and post-independence, and given the Maasai a reputation for being backward.
Even so, despite contributing little to the regional economy, subsistence pastoralism, prior to the advent of tourism, was the major land use throughout most of what is now the Ngorongoro Conservation Area.
