Rapid urban and industrial development is altering the landscape of Arabia at an alarming rate. However, these landscapes are archives of hundreds of thousands of years of environmental change, and provide an important framework for understanding the demographic variability of human populations in the distant past. Multi-proxy data from an extensive suite of river and lake deposits along the western Hajar Mountains can be used to develop a sensitive record of climatically-driven environmental change. The dispersals of prehistoric populations are fundamentally linked to the availability of freshwater resources within the Arabian Peninsula. In particular, the occupation of archaeological sites such as Jebel Faya (UAE), are seemingly synchronous with increased rainfall and the expansion of vegetation throughout the region. Despite the potential of palaeoenvironmental investigations in this region to advance knowledge of early human-environment interactions, to date there are only a few studies with good chronometric control. Therefore, building an advanced and securely dated framework of Arabian palaeohydrology from fan systems within the region has the potential to generate a high-resolution record of the water resources available to our ancestors, and the environmental pressures influencing their mobility. This record has huge educational value for regional museums and heritage organisations.Research questions: The main aim of this project is to develop a framework of climatically driven landscape change from SE Arabia utilising a series of dated fluvial/alluvial sediment sequences situated along the western Hajar Mountains. The overarching research questions will be: 1. What is the nature and timing of drainage activation from the western Hajar region of SE Arabia? 2. How did the abiotic and biotic components of SE Arabian environments respond to these periods of drainage activation? 3. How do such changes correspond with wider regional and global climate variability? 4. What implications did these changes in water resource availability have for Early Homo sapiens and their demography throughout the Mid-Late Pleistocene? 5. How can these findings be used to improve presentation of the stories of pre-historic peoples in museums and heritage sites within the region?

快速的城市和工业发展正在以惊人的速度改变阿拉伯的景观。但是，这些景观是数十万年的环境变化的档案，并为了解遥远的过去人口的人口变化提供了一个重要的框架。来自西哈尔山脉沿线的河流和湖泊沉积物的多种数据数据可用于发展气候驱动的环境变化的敏感记录。史前人群的分散与阿拉伯半岛内淡水资源的可用性有关。特别是，诸如Jebel Faya（UAE）之类的考古遗址的占领似乎与降雨量增加和整个地区的植被的扩张似乎同步。尽管该地区的古环境研究有潜力，以提高人们对早期人类环境相互作用的了解，但迄今为止，只有少数研究具有良好的时间表控制。因此，从该地区范围内建立了来自粉丝系统的阿拉伯古水学框架的先进且牢固的日期框架，有可能产生高分辨率的水资源记录，并为我们祖先提供的水资源以及影响其移动性的环境压力。该唱片对区域博物馆和遗产组织具有巨大的教育价值。研究问题：该项目的主要目的是从SE阿拉伯使用一系列过时的河流/冲积性沉积物沿西部的Hajar开发一个气候驱动的景观变化框架。山。总体研究问题将是：1。来自SE阿拉伯西部哈哈地区的排水激活的性质和时机是什么？ 2。SE阿拉伯环境的非生物和生物成分如何应对这些排水激活时期？ 3。这种变化与更广泛的区域和全球气候变异性如何相对应？ 4.在整个更新世中，这些水资源可用性的这些变化对早期的智人及其人口有什么影响？ 5。如何使用这些发现来改善该地区博物馆和遗产中史前民族的故事的介绍？
