Résumé
This contribution aims to analyse what were the adaptation strategies of agropastoral systems vis à-vis water stress over the last millennium in Central Asia. Based on paleoenvironmental analyses carried out on the sediment infilling of Lake Kanbeshbulak (southern part of the Hissar mountain range, Uzbekistan), we will reconstruct the long-term variability of soil erosion (sedimentology and, elemental geochemistry) in relation to indicators on the nature and relative intensity of the agropastoral practices (palynology carried out on the same cores). Those results will be put into a Human perspective through comparisons with historical sources. In particular, we will propose a special focus on the Medieval Islamic Period to discuss the hypotheses that regional climate changes, by modifying water resource availability locally, might have impacted crops and pastoral livestock productions, triggering economic losses and social contestations unevenly addressed by the succeeding political powers.
