“…Indeed, it is now clear that the period was characterised by significant temporal and spatial climatic variability, in turn highlighting the importance of understanding the evolution of the terrestrial landscape at the local level when examining climate -human interactions. This variability is evident throughout the Peninsula today, largely as a consequence of changes in elevation, with higher precipitation in the mountainous terrain which runs along the eastern (al-Hajar Mountains, Oman), southern (Dhofar Mountains, Oman, and the Hadramawt Plateau, Yemen), and western (Yemeni Highlands) fringes of the Peninsula (Glennie and Singhvi, 2002). In addition, significant rainfall events, resulting in flash-flooding, have been recorded throughout parts of the UAE and Oman (Membury, 1997;Kwarteng et al, 2009).…”

An early-to mid-Holocene humid phase has been identified in various Arabian geoarchives, although significant regional heterogeneity has been reported in the onset, duration and stability of this period. A multi-proxy lake and dune record from Wahalah in the United Arab Emirates (UAE) documents significant variations in hydrology, biological productivity and landscape stability during the first half of the Holocene. These data reveal that post-Last Glacial Maximum dune emplacement continued into the earliest part of the Holocene, with the onset of permanent lacustrine sedimentation at the site commencing ~8.5 ka cal. BP. A long-term shift towards more arid conditions is inferred between ~7.8 -5.9 ka cal. BP, with intermittent flooding of the basin and distinct phases of instability throughout the catchment area. This transition is linked to the southwards migration of the Intertropical Convergence Zone (ITCZ) and associated weakening of monsoon rains. A peak in landscape instability is recorded between ~5.9 -5.3 ka cal. BP and is marked by a pronounced increase in regional dune emplacement. These variations are considered alongside the record of human settlement raising important questions *Manuscript Click here to view linked References about the interactions between population demographics, climate and environment in southeast Arabia during the Neolithic.

“…This enables stratigraphical relationships between multiple dune sequences, alluvial fans and wadi deposits across the Emirates to be deduced (Figure 2). Although it has long been recognised that the dune fields of the Rub' al-Khali comprise distinct sectors characterised by different dominant dune morphologies (Glennie and Singhvi, 2002;Stokes, 2003, 2004;Stokes and Bray 2005;Atkinson et al, 2012;Farrant et al, 2012a), what has not been generally recognised is the presence of extensive palaeodune sequences which provide evidence of earlier dune accumulation phases which underlie many of the more recent unconsolidated dunes or in some cases are coeval with them.…”

“…Most previous studies were concentrated in a relatively narrow strip on the eastern fringe of the dune-field in the far northeast of the UAE between Ras al Khaimah, and Al Ain (Goudie et al, 2000;Parker andGoudie, 2007, 2008;Atkinson et al, 2011Atkinson et al, , 2012Atkinson et al, , 2013Leighton et al, 2013Leighton et al, , 2014 and in the Liwa/al-Qafa region in Abu Dhabi emirate (Stokes and Bray, 2005). Glennie and Singhvi (2002) sampled a few sites across Abu Dhabi emirate, but provided little context for the dates, nor gave accurate locations. Moreover, these studies have for the most part focussed on the younger unconsolidated dunes (Figure 4), with the exception of Stokes and Bray (2005) who sampled some of the underlying palaeodunes.…”

Located at the crossroads between Africa and Eurasia, Arabia occupies a pivotal position for human migration and dispersal during the Late Pleistocene. Deducing the timing of humid and arid phases is critical to understanding when the Rub' al-Khali desert acted as a barrier to human movement and settlement. Recent geological mapping in the northern part of the Rub' al-Khali has enabled the Quaternary history of the region to be put into a regional stratigraphical framework. In addition to the active dunes, two significant palaeodune sequences have been identified. Dating of key sections has enabled a chronology of dune accretion and stabilisation to be determined. In addition, previously published optically stimulated luminescence (OSL) dates have been put in their proper stratigraphical context, from which a record of Late Pleistocene dune activity can be constructed. The results indicate the record of dune activity in the northern Rub' al-Khali is preservation limited and is synchronous with humid events driven by the incursion of the Indian Ocean monsoon.

“…In their exhaustive analysis on Quaternary stratigraphy and environments of the Arabian Peninsula, Glennie and Singhvi [51] confirm the long-term persistence of the Shamal, but state a generally weaker intensity during interglacials. While decreasing trends of the NAO and the ISM may indicate a Shamal stronger than today over most of the Holocene, and hence, higher migration rates, wetter conditions during the early to mid-Holocene transition identified in many parts of the Arabian Peninsula [50,[52][53][54] may have stimulated vegetation cover slowing down sand flux and migration speed [4,11,55,56].…”

Migration of Barchan Dunes in Qatar–Controls of the Shamal, Teleconnections, Sea-Level Changes and Human Impact

Abstract:Barchan dune fields are a dominant landscape feature in SE Qatar and a key element of the peninsula's geodiversity. The migration of barchan dunes is mainly controlled by dune size, wind patterns, vegetation cover and human impact. We investigate the variability of dune migration in Qatar over a time period of 50 years using high-resolution satellite and aerial imagery. We then explore its relation to the regional Shamal wind system, teleconnection patterns, and limitations in sand supply associated with the transgression of the Arabian Gulf. Strong size-dependent differences in migration rates of individual dunes as well as significant decadal variability on a dune-field scale are detected, which are found to correlate with the intensity of the North Atlantic Oscillation (NAO) and the Indian Summer Monsoon (ISM), in particular during years of relatively strong (weak) summer Shamals. High uncertainties associated with the extrapolation of migration rates back into the Holocene, however, do not permit further examination of the timing of the loss of sand supply and the onset of the mid-Holocene relative sea-level (RSL) highstand. For the youngest phase considered in this study (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015), human impact has likely accelerated dune migration under a weakening Shamal regime through sand mining and excessive vehicle traffic upwind of the core study area.
