摘要
This paper examines the recently growing adoption of non-pastoral livelihood strategies among the Borana pastoralists in southern Ethiopia. A large portion of the current non-pastoral participation is in petty and natural resource-based activities. Pastoral and crop production functions are estimated using the Cobb-Douglas model to analyse the economic rationale behind the growing pastoralist shift to cultivation and other non-pastoral activities. The low marginal return to labour in traditional pastoralism suggests the existence of surplus labour that can gainfully be transferred to non-pastoral activities. An examination of the pastoralist activity choices reveals that the younger households with literacy and more exposure to the exchange system display a more diversified income portfolio preference. The findings underscore the importance of human capital investment and related support services for improving the pastoralist capacity to manage risk through welfare-enhancing diversified income portfolio adoption.
