International audience. While some works have suggested that large-scale mobilities and conflicts in Central Asia and Western Asia (e.g. Mongol invasions) have been linked to climatic events, in this contribution we choose to move the focus to local human-climate interactions. We will specifically investigate what were the adaptation strategies of agropastoral systems vis-à-vis water stress, in the frame of various political constructions, over the last 1500 years. Based on palaeohydrological and paleoecological investigations carried out on selected lake sedimentary archives of Iran and Uzbekistan, we will reconstruct the long-term variability of lake evaporation and runoff processes (sedimentology, geochemistry), together with indicators on the nature and relative intensity of the agropastoral practices (palynology). 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.
