Abstract. The major objectives of this paper are: (1) to review the pros and cons scenarios past anthropogenic land cover change (ALCC) developed during last ten years, (2) discuss issues related pollen-based reconstruction land-cover introduce a new method, REVEALS (Regional Estimates VEgetation Abundance from Large Sites), infer long-term records pollen data, (3) present project (LANDCLIM: LAND – CLIMate interactions in NW Europe Holocene) currently underway, show preliminary results...
Abstract We present quantitative reconstructions of regional vegetation cover in north‐western Europe, western Europe north the Alps, and eastern for five time windows Holocene [around 6k, 3k, 0.5k, 0.2k, 0.05k calendar years before ( bp )] at a 1° × spatial scale with objective producing descriptions suitable climate modelling. The REVEALS model was applied on 636 pollen records from lakes bogs to reconstruct past 25 plant taxa grouped into 10 plant‐functional types three land‐cover...
Abstract. Quantitative reconstructions of past land cover are necessary to determine the processes involved in climate–human–land-cover interactions. We present first temporally continuous and most spatially extensive pollen-based land-cover reconstruction for Europe over Holocene (last 11 700 cal yr BP). describe how vegetation has been quantified from pollen records at a 1∘ × spatial scale using “Regional Estimates VEgetation Abundance Large Sites” (REVEALS) model. REVEALS calculates...
Anthropogenic land cover change (ALCC) is the most important transformation of Earth system that occurred in preindustrial Holocene, with implications for carbon, water and sediment cycles, biodiversity provision ecosystem services regional global climate. For example, anthropogenic deforestation Eurasia may have led to feedbacks climate system: both biogeophysical, regionally amplifying winter cold summer warm temperatures, biogeochemical, stabilizing atmospheric CO 2 concentrations thus...
Abstract. This study aims to evaluate the direct effects of anthropogenic deforestation on simulated climate at two contrasting periods in Holocene, ~6 and ~0.2 k BP Europe. We apply Rossby Centre regional model RCA3, a with 50 km spatial resolution, for both time periods, considering three alternative descriptions past vegetation: (i) potential natural vegetation (V) by dynamic LPJ-GUESS, (ii) land use (deforestation) from HYDE3.1 (History Database Global Environment) scenario (V + H3.1),...
In this paper we test the performance of Regional Estimates VEgetation Abundance from Large Sites (REVEALS) model using pollen records multiple small sites. We use Holocene large and sites in southern Sweden to identify what is/are most significant variable(s) affecting REVEALS-based reconstructions, i.e. type site (lakes and/or bogs), number sites, size, location relation vegetation zones, distance between To achieve objective grouped according (i) two major modern zones study region, (ii)...
Land-cover changes have a clear impact on local climates via biophysical effects. European land cover has been affected by human activities for at least 6000 years, but possibly longer. It is thus highly probable that humans altered climate before the industrial revolution (AD1750–1850). In this study, and vegetation years (6 ka) ago investigated using one global model, two regional models, dynamical pollen-based reconstruction of past model pollen-vegetation relationship statistical spatial...
Reliable quantitative vegetation reconstructions for Europe during the Holocene are crucial to improving our understanding of landscape dynamics, making it possible assess past effects environmental variables and land-use change on ecosystems biodiversity, mitigating their in future. We present here most spatially extensive temporally continuous pollen-based plant cover (at a spatial resolution 1° × 1°) over (last 11.7 ka BP) using ‘Regional Estimates VEgetation Abundance from Large Sites’...
Realistic and accurate reconstructions of past vegetation cover are necessary to study environmental changes. This is important since the effects human land-use changes (e.g. agriculture, deforestation afforestation/reforestation) on biodiversity climate still under debate. Over last decade, development, validation, application pollen-vegetation relationship models have made it possible estimate plant abundance from fossil pollen data at both local regional scales. In particular, REVEALS...
Abstract Questions We investigated the changing role of climate, forest fires and human population size in broad‐scale compositional changes Holocene vegetation dynamics before after onset farming Sweden (at 6,000 cal yr BP) Finland 4,000 BP). Location Southern central Sweden, SW SE Finland. Methods regional plant abundances were reconstructed using REVEALS model on selected fossil pollen records from lakes. The relative importance composition was assessed variation partitioning. Past...
Abstract Climate change and human activities influence the development of ecosystems, with demand ecosystem services altering both land use cover. Fossil pollen records provide time series vegetation characteristics, aim this study was to create spatially continuous reconstructions cover through Holocene in southern Sweden. The Landscape Reconstruction Algorithm (LRA) applied obtain quantitative pollen-based at local scales, accounting for production, dispersal, deposition mechanisms....

Abstract. This study aims to evaluate the direct effects of anthropogenic deforestation on simulated climate at two contrasting periods in Holocene, ~6 k BP and ~0.2 Europe. We apply RCA3, a regional model with 50 km spatial resolution, for both time periods, considering three alternative descriptions past vegetation: (i) potential natural vegetation (V) by dynamic LPJ-GUESS, (ii) land cover (deforestation) as HYDE (V + H), (iii) KK K). The estimates are closer set pollen-based...
