Communities inhabiting the arid and semi-arid areas of eastern Africa have long suffered from and engaged in pastoral conflicts. However, since some countries in the region became oil producers, the conditions affecting pastoral conflicts have changed. This study examines how oil extraction may influence pastoral conflicts by using a survey experiment conducted in Turkana County, Kenya, on a sample of 801 respondents. The study finds that overall, respondents’ perceived risks of pastoral conflicts decrease when they are primed about the consequences of oil extraction leading to fundamental changes in pastoral livelihoods, such as an increase in employment opportunities in the oil sector and rapid social changes. The residents of Turkana view pastoral conflicts as customary as long as pastoralism continues and fundamental changes to pastoralism-based livelihoods originating from oil discovery and extraction may lead to a decrease in the pastoralist population engaging in pastoral conflicts.

The spread and persistence of early forms of mobile food production throughout Africa depended on the ability of herding communities to adapt to novel social and environmental challenges. This article presents the first quantitative technological analysis of lithic assemblages from the earliest eastern African pastoralist sites, located in the Lake Turkana Basin of northern Kenya. In this region, transitions to pastoralism involved the adoption of a new, regionally homogeneous technological strategy, which emphasised utility and flexibility. This research provides new insights into how early herders were able to spread through sub-Saharan Africa during a period of extreme climate change.

In rural Kenya, the main visible security force is the Kenya Police Reserve, an unpaid force guarding localities and armed by the state. Turkana County faces challenges of low state penetration, small arms flows, and armed intercommunal conflict. The state has a weak hold on Kenya Police Reservists (KPRs) and their arms, and this situation is weakening further as many move into paid private security roles, including guarding oil exploration and drilling sites. Security is critical in view of the recent oil discovery and ensuing land disputes which could trigger widespread conflict, and the recent devolution of development and administrative functions to counties in Kenya.

The northern Kenya Rift is bounded on the west by uplands of Turkana which comprise horst-like blocks that include metamorphic basement rocks, locally overlain unconformably by the Cretaceous Lubur Sandstone, in turn overlain by predominantly volcanic sequences in which relatively thin sedimentary packages occur. Amphibolite facies crystalline rocks of the basement yield Early Palaeozoic K–Ar cooling ages reflecting the Pan-African Orogeny. Volcanism in Turkana was initiated through voluminous eruptions of transitional tholeiitic basalts commencing about 36 Ma ago in the Late Eocene, with some evidence for concomitant rhyolitic volcanism. Volcanism became dominantly rhyolitic in the interval from about 27 to 23 Ma ago, but remained bimodal as basaltic lavas are also known from this period. From about 19 to 15 Ma or younger, basaltic volcanism again dominated, often alkaline in nature, with thin but significant sedimentary sequences interleaved that have yielded important vertebrate faunal assemblages. Parallels exist between the volcanic history recorded in Turkana and that found in the Nabwal Hills east of Lake Turkana. In the southern Turkana region, oil exploration by seismic methods and deep drill holes has shown the existence of northerly-trending half-graben with up to 7 km of fill, and that these developed from at least Oligocene and possibly Late Eocene times. This suggests that the widespread basaltic volcanism at about 36 Ma ago (Late Eocene) heralds an earlier initiation of the Kenya Rift in northern Kenya than most workers have previously suggested.
