The extent of forest in dryland biomes

  
Science, Vol. 356, No. 6338. (12 May 2017), pp. 635-638, https://doi.org/10.1126/science.aam6527

Abstract

[Mapping the world's dry forests] The extent of forest area in dryland habitats, which occupy more than 40% of Earth's land surface, is uncertain compared with that in other biomes. Bastin et al. provide a global estimate of forest extent in drylands, calculated from high-resolution satellite images covering more than 200,000 plots. Forests in drylands are much more extensive than previously reported and cover a total area similar to that of tropical rainforests or boreal forests. This increases estimates of global forest ...

 

Comment on “The extent of forest in dryland biomes”

  
Science, Vol. 358, No. 6362. (26 October 2017), eaao0166, https://doi.org/10.1126/science.aao0166

Abstract

Bastin et al. (Reports, 12 May 2017, p. 635) claim to have discovered 467 million hectares of new dryland forest. We would argue that these additional areas are not completely “new” and that some have been reported before. A second shortcoming is that not all sources of uncertainty are considered; the uncertainty could be much higher than the reported value of 3.5%. ...

 

Response to Comment on “The extent of forest in dryland biomes”

  
Science, Vol. 358, No. 6362. (26 October 2017), eaao2070, https://doi.org/10.1126/science.aao2070

Abstract

Schepaschenko et al. question our findings, claiming that we did not refer to all existing maps and that we did not account for all sources of uncertainty. In our response, we detail our selection criteria for reference maps, which clarify why the work of Schepaschenko et al. was not used, and we explain why our uncertainty assessment is complete and how it was misunderstood by Schepaschenko et al. ...

Effects of slope angle and aspect on plant cover and species richness in a humid Mediterranean badland

  
Earth Surface Processes and Landforms, Vol. 39, No. 13. (October 2014), pp. 1705-1716, https://doi.org/10.1002/esp.3549

Abstract

Soil erosion is one of the most severe land degradation processes in the Mediterranean region. Although badlands occupy a relatively small fraction of the Mediterranean area, their erosion rates are very high. Many studies have investigated to what extent vegetation controls soil erosion rates. This study, however, deals with the impact of erosion on vegetation establishment. In semi-arid badlands of the Mediterranean, soil water availability constitutes the main limiting factor for vegetation development. As a consequence, south-facing slopes are typically less ...

 

Satellites reveal contrasting responses of regional climate to the widespread greening of Earth

  
Science (25 May 2017), eaal1727, https://doi.org/10.1126/science.aal1727

Abstract

[The vegetation-climate loop] Just as terrestrial plant biomass is growing in response to increasing atmospheric CO2, climate change, and other anthropogenic influences, so is climate affected by those variations in vegetation. Forzieri et al. used satellite observations to analyze how changes in leaf area index (LAI), a measure of vegetation density, have influenced the terrestrial energy balance and local climates over the past several decades. An increase in LAI has helped to warm boreal zones through a reduction of surface albedo and ...

 

Spatial vegetation patterns and imminent desertification in Mediterranean arid ecosystems

  
Nature, Vol. 449, No. 7159. (13 September 2007), pp. 213-217, https://doi.org/10.1038/nature06111

Abstract

Humans and climate affect ecosystems and their services1, which may involve continuous and discontinuous transitions from one stable state to another2. Discontinuous transitions are abrupt, irreversible and among the most catastrophic changes of ecosystems identified1. For terrestrial ecosystems, it has been hypothesized that vegetation patchiness could be used as a signature of imminent transitions3, 4. Here, we analyse how vegetation patchiness changes in arid ecosystems with different grazing pressures, using both field data and a modelling approach. In the modelling approach, ...

 

A review of the combination among global change factors in forests, shrublands and pastures of the Mediterranean Region: beyond drought effects

  
Global and Planetary Change, Vol. 148 (January 2017), pp. 42-54, https://doi.org/10.1016/j.gloplacha.2016.11.012

Abstract

[Highlights] [::] Different global change factors combine causing unprecedented ecological effects. [::] Much more complex interactions arise when combinations occur together. [::] Drought should be considered when designing and applying management policies. [::] Conserving Mediterranean terrestrial ecosystems is a collective effort. [Abstract] Climate change, alteration of atmospheric composition, land abandonment in some areas and land use intensification in others, wildfires and biological invasions threaten forests, shrublands and pastures all over the world. However, the impacts of the combinations between global change factors are not well understood despite ...

 

Mediterranean habitat loss under future climate conditions: assessing impacts on the Natura 2000 protected area network

  
Applied Geography, Vol. 75 (2016), pp. 83-92, https://doi.org/10.1016/j.apgeog.2016.08.003

Abstract

[Highlights] [::] The Mediterranean climate domain is projected to loss 11–25% of its current extent. [::] Projected losses of the Mediterranean climate are due to shifts of the arid domain. [::] The Mediterranean domain is projected to shift by 53–121% of its current size. [::] These changes are projected to affect 15–23% of the Mediterranean Natura 2000 sites. [Abstract] The Mediterranean basin is a global hotspot of biological diversity and the most rich biodiversity region in Europe. Nevertheless, climate-driven habitat loss is one of the most serious ...

 

Homogenization in forest performance across an environmental gradient – The interplay between rainfall and topographic aspect

  
Forest Ecology and Management, Vol. 310 (December 2013), pp. 256-266, https://doi.org/10.1016/j.foreco.2013.08.026

Abstract

[Highlights] [::] Large- and small-scale factors interact in their effect on forest performance. [::] Performance homogenization across habitats was linearly related to rainfall. [::] Homogenization was associated with drought conditions, both in time and space. [Abstract] This study aimed to investigate the interaction between local and regional environmental factors that affect forest performance during drought periods. In previous studies, contradictory results regarding the effect of aspect on forests performance, under different settings, were reported. However, each study focused on a different forest ecosystem at a different ...

 

Vegetation-microclimate feedbacks in woodland-grassland ecotones

  
Global Ecology and Biogeography, Vol. 22, No. 4. (April 2013), pp. 364-379, https://doi.org/10.1111/geb.12000

Abstract

[Aim] Climatic conditions exert a strong control on the geographic distribution of many woodland-to-grassland transition zones (or ‘tree lines’). Because woody plants have, in general, a weaker cold tolerance than herbaceous vegetation, their altitudinal or latitudinal limits are strongly controlled by cold sensitivity. While temperature controls on the dynamics of woodland–grassland ecotones are relatively well established, the ability of woody plants to modify their microclimate and to create habitat for seedling establishment and growth may involve a variety of processes that are ...

 

Precipitation–vegetation coupling and its influence on erosion on the Loess Plateau, China

  
CATENA, Vol. 64, No. 1. (30 November 2005), pp. 103-116, https://doi.org/10.1016/j.catena.2005.07.004

Abstract

The relationships between precipitation, vegetation and erosion are important and are unsolved issues in the field of earth surface processes. Based on data from the Loess Plateau of China, some non-linear relationships between forest cover (Cf), mean annual rainfall erosivity (Re) and annual precipitation (Pm) have been found. A threshold has been identified at Pm = 450 mm, that is, when Pm is < 450 mm, Cf is low and basically does not vary with Pm; when Pm exceeds 450 mm, Cf increases rapidly. ...

 

A comparative study of rainfall erosivity estimation for southern Italy and southeastern Australia

  
Hydrological Sciences Journal, Vol. 44, No. 1. (1 February 1999), pp. 3-24, https://doi.org/10.1080/02626669909492199

Abstract

Abstract In this paper, using Sicilian and Australian rainfall intensity data, a comparison between different estimators (modified Fournier index F, FF index) of the rainfall erosivity factor in the USLE was made. The relationship between the modified Fournier index and the mean annual rainfall, P, was theoretically derived. The K constant, linking the FF index and P, and its cumulative distribution function (CDF) were used to establish hydrological similitude among different geographical regions of southern Italy and southeastern Australia. To predict ...

 

Increasing drought under global warming in observations and models

  
Nature Climate Change, Vol. 3, No. 1. (5 August 2012), pp. 52-58, https://doi.org/10.1038/nclimate1633

Abstract

Historical records of precipitation, streamflow and drought indices all show increased aridity since 1950 over many land areas1, 2. Analyses of model-simulated soil moisture3, 4, drought indices1, 5, 6 and precipitation-minus-evaporation7 suggest increased risk of drought in the twenty-first century. There are, however, large differences in the observed and model-simulated drying patterns1, 2, 6. Reconciling these differences is necessary before the model predictions can be trusted. Previous studies8, 9, 10, 11, 12 show that changes in sea surface temperatures have large ...

 

Greater ecosystem carbon in the Mojave Desert after ten years exposure to elevated CO2

  
Nature Clim. Change, Vol. 4, No. 5. (6 May 2014), pp. 394-397, https://doi.org/10.1038/nclimate2184

Abstract

Carbon dioxide is the main greenhouse gas inducing climate change. Increased global CO2 emissions, estimated at 8.4 Pg C yr−1 at present, have accelerated from 1% yr−1 during 1990–1999 to 2.5% yr−1 during 2000–2009 (ref. 1). The carbon balance of terrestrial ecosystems is the greatest unknown in the global C budget because the actual magnitude, location and causes of terrestrial sinks are uncertain2; estimates of terrestrial C uptake, therefore, are often based on the residuals between direct measurements of the atmospheric ...

Climate and surface properties: hydrological response of small arid and semi-arid watersheds

  
Geomorphology, Vol. 42, No. 1-2. (January 2002), pp. 43-57, https://doi.org/10.1016/s0169-555x(01)00072-1

Abstract

A positive relationship between annual rainfall and geomorphic processes (runoff and erosion rates) and environmental factors (water regime, soil and vegetation cover) is often assumed for arid and semi-arid areas with an annual rainfall in the range of 100-300 mm. This assumption disregards the fact that changes along a climatic gradient, at desert margins, are not limited to purely climatic factors. They are often accompanied by a parallel change in surface properties; especially the relative extent of rocky or soil covered ...
