Nomad, semi-nomad and transhumant used to be the most frequent mobility types of pastoral society. Nowadays, these categories become questionable in regard to the evolution of the pattern life of families in southern Morocco. How do we link past and present mobility? What have been the changes? In this article, we question the relevance of the aforementioned categories of mobility, as defined by the actors of scientific research and development, to analyze and classify pastoral mobility management that condition the way of life and the adaptive capacities of Saharan societies, by mobilizing different corpus such as ‘récit de vie’ and typology. This study was conducted downstream in the Drâa Valley (Morocco). If the majority of breeders claim to be nomads as soon as they practice a pattern of living in a tent over the course of a year, the typology of mobility pattern reveals intra- and inter-annual fluctuations of its management embedded in their adaptive strategies to climate variability or economic constraints which makes difficult to classify breeders according to the mobility only. In this context, developing climate change mitigation interventions for pastoral societies need to understand and integrate the permanent changing pattern of mobility management in these pastoral societies.

游牧民族，半游牧民族和超人类曾经是牧民社会最频繁的流动类型。时至今日，这些类别对于摩洛哥南部家庭生活方式的演变已成为可疑的问题。我们如何联系过去和现在的流动性？发生了什么变化？在本文中，我们质疑由科学研究和发展参与者定义的上述流动性类别的相关性，以通过调动不同的生活方式来分析和分类制约撒哈拉沙漠社会生活方式和适应能力的牧民流动性管理语料库，例如“récitde vie”和类型学。这项研究是在德拉河谷（摩洛哥）的下游进行的。如果大多数饲养员在一年的时间里实践出一种在帐篷中生活的方式，便声称自己是游牧民族，迁徙模式的类型学揭示了其管理中的年内和年际波动，这些变化嵌入其对气候变化或经济限制的适应策略中，这使得仅根据迁徙性对育种者进行分类变得困难。在这种情况下，为牧民社会开发减缓气候变化的干预措施需要了解并整合这些牧民社会中流动管理的永久性变化模式。
