Mixed camelids-sheep herds, management practices and viability analysis : some considerations for a sustainability framework of Andean pastoral systems.

Abstract : In this communication we aim at documenting how herd management strategies, particularly those related to herd composition and to breeding and off-take practices, contribute to satisfying basic household needs and influencing the sustainability of the mixed llamas-sheep pastoral systems of Bolivia. An extensive survey to assess factors affecting herd composition, and herd management monitoring were performed, focusing particularly on breeding and off-take practices. A model was built, using the viability theory, in order to assess the incidence of these management practices along with climatic uncertainty on long-term household survival. Results show that llamas and sheep play complimentary roles in the functioning of the overall system, due to their differentiated biological characteristics and management. Raising these two species together is viewed as a sound strategy to limit various kinds of risks. The sustainability of the system depends on the balance between the two species, managed with a variety of practices, and the wealth of the household. These considerations lead to the proposal of a conceptual framework based on the links between pastoral family wealth and the range of practices they can mobilise in order to face environmental limitations as well as endogenous uncertainty related to household decisions.
