Previous studies have proposed that potential vegetation in the Mediterranean maintained a wetter climate during the Roman Period until the initiation of large scale deforestation. The reduction in evapotranspirative fluxes associated with deforestation is suggested to have caused climatic aridification leading to the establishment of the present-day Mediterranean climate. There is also evidence to indicate that during the Roman Period Mediterranean climate was influenced by low frequency… Expand

A GIS approach to palaeovegetation modelling in the Mediterranean: the case study of southwest Turkey
Vegetation is a critical component of Mediterranean palaeolandscape studies, however variable data quality and quantity, a lack of understanding of Mediterranean vegetation processes, and complexExpand
The mid‐Holocene vegetation of the Mediterranean region and southern Europe, and comparison with the present day
Aim To contribute to the intense debate surrounding the relative influence of climate and humans on Mediterranean-region land cover over the past 6000 years, we assess the Holocene biogeography andExpand
Controls on late-Holocene drift-sand dynamics: The dominant role of human pressure in the Netherlands
It is evident that human pressure on the landscape was most influential on initiating sand drifting: this is supported by more frequent occurrences close to routes and the uninterrupted increase of drift-sand activity from AD 900 onwards, a period of high population density and large-scale deforestation.

Modeling the effects of vegetation on Mediterranean climate during the Roman Classical Period: Part I: Climate history and model sensitivity
Abstract This is the first of a two-part study to construct a vegetation map around the Mediterranean Sea that is an accurate representation of conditions two millennia ago, and to use this data inExpand
Modeling the effects of vegetation on Mediterranean climate during the Roman Classical Period
Abstract The purpose of this study is to perform a high-resolution general circulation model (GCM) experiment to quantify the sensitivity of regional climate to change in vegetation around theExpand
Relation between century-scale Holocene arid intervals in tropical and temperate zones
CLIMATE records from lake sediments in tropical Africa, Central America and west Asia show several century-scale arid intervals during the Holocene1–10. These may have been caused by temporaryExpand
Climate change at the 4.2 ka BP termination of the Indus valley civilization and Holocene south Asian monsoon variability
