Extensive drought in the 1970s and 1980s prompted national and international development efforts aimed at the pastoralist populations of Marsabit District of Kenya. Famine relief efforts by the Catholic Church and the African Inland Mission contributed to the settling of former nomads and the growth of small towns, while international development efforts, including UNESCO's Integrated Project in Arid Lands (IPAL) focused on range conservation and the improvement of livestock marketing. The sedentarization of pastoralists has led to greater access to health care, education, and other social services, but has also contributed to economic differentiation and rural proletarianization. Local economies are now based on a combination of subsistence pastoralism, livestock marketing, and wage-labor, indicating that the process of sedentarization is a complex one with varying consequences for different sectors of the population.
