A decrease in precipitation due to climate change will likely threaten their traditional livelihood strategy. We examine whether the pastoralists explicitly prefer certain alternative strategies or if their reactions will be contingent. Our analysis uses standardized interviews focussing on two aspects: firstly, which resources are necessary for the pastoralists to be able to choose a livelihood strategy? Secondly, to what degree are expectations of well-being satisfied by alternative strategies? To assign levels of predictability to all investigated strategies, we analyze the interviews using simple methods of partial order theory. We find that under perceived precipitation scarcity, 38% of pastoralists would explicitly opt for sedentarity and localized pastoralism as alternative strategy. Unclear preferences are given for 25% of the cases. Considering a policy scenario of enhanced access to education and capital, our analysis indicates commercial pastoralism as dominant alternative. However, such a scenario would increase the share of unclear preferences to 43%, which increases the likelihood of a contingent development. The method we propose can be considered as a mathematical basis for the concept of historical contingency. © 2011 Elsevier Inc. All rights reserved.

Introduction In our study we assess the predictability of future livelihood strategies of transhumant pastoralists in semi-arid Morocco. The region of interest is likely to experience considerable alterations in precipitation during the 21st century [1], leading to modications of livelihood strategies and agricultural techniques. The extent to which livelihood strategies will be modied is unclear, since socio-ecological systems are traditionally considered as very difcult to predict. Reasons for poor predictability are a high complexity of internal structures and involvement of partly unpredictable human agency (e.g. [2,3]). Given these constraints on predictability, social sciences mostly investigate socio-ecological systems from a historical perspective. Random events, which strongly impact the subsequent development of these systems, are considered as so-called historical contingencies which lead to path-dependence [47]. Historical contingencies are seen as an irreducible gap in the causal narrative [5] and therefore principally prevent valid predictions about socio-ecological systems.
