The role of the permanent wilting point in controlling the spatial distribution of precipitation

  
Proceedings of the National Academy of Sciences, Vol. 115, No. 22. (29 May 2018), pp. 5692-5697, https://doi.org/10.1073/pnas.1718842115

Abstract

[Significance] One basic distinction between land and ocean is that the land can dry out. We show that this is of fundamental importance for the precipitation distribution over land as it brings precipitation from the precipitating region to the nonprecipitating region. This process prevents the land–atmosphere system from sustaining precipitation over the same region and thus acts against drought or the formation of desert. Paradoxically, although dry atmospheres are known to hamper moist convection, drying the soil to its permanent wilting point ...

 

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, ...

 

Passing the point of no return

  
Science, Vol. 354, No. 6316. (02 December 2016), pp. 1109-1109, https://doi.org/10.1126/science.aal2188

Abstract

[Excerpt] In the field of ecology, regime shifts are massive changes in function and character that occur when an ecosystem passes a tipping point. Regime shifts sometimes have severe consequences for human well-being through losses of ecosystem services, including desertification in arid regions and marine fisheries collapses. These changes are difficult to predict and sometimes impossible to reverse. For these reasons, understanding how to anticipate and prevent regime shifts is one of the most important challenges faced by environmental scientists. [\n] Theoretical analyses ...

 

Sustainable land use in the European Union

  
CULTIVAR Cadernos de Análise e Prospetiva, Vol. 2 (2015), pp. 13-20

Abstract

[Excerpt: Introduction] Soil is defined as the top layer of the earth’s crust. It is formed by mineral particles, organic matter, water, air and living organisms. In fact, soil is an extremely complex, variable and living medium. It can be considered essentially as a non-renewable resource since soil formation is an extremely slow process. Soil provides us with food, biomass and raw materials. It serves as a platform for human activities and landscape. It is also an archive of heritage and plays ...

Status of desertification in the Mediterranean region

  
In Water Scarcity, Land Degradation and Desertification in the Mediterranean Region (2009), pp. 33-73, https://doi.org/10.1007/978-90-481-2526-5_3

Abstract

Assessment of the status of Mediterranean desertification requires a robust and agreed upon definition of desertification, which is still lacking, partly due to the widespread use of “desertification” either interchangeably or in conjunction with “land degradation”. By definition desertification is a subset of land degradation confined to drylands, thus adding “land degradation” to “desertification” implies relevance of the UNCCD to land degradation in both drylands and non-drylands, globally and in the Mediterranean. Another interpretation for pairing “desertification” and “land degradation” is ...

 

Climatic feedbacks and desertification: the Mediterranean model

  
Journal of Climate, Vol. 18, No. 5. (1 March 2005), pp. 684-701, https://doi.org/10.1175/jcli-3283.1

Abstract

Mesometeorological information obtained in several research projects in southern Europe has been used to analyze perceived changes in the western Mediterranean summer storm regime. A procedure was developed to disaggregate daily precipitation data into three main components: frontal precipitation, summer storms, and Mediterranean cyclogenesis. Working hypotheses were derived on the likely processes involved. The results indicate that the precipitation regime in this Mediterranean region is very sensitive to variations in surface airmass temperature and moisture. Land-use perturbations that accumulated over historical ...

[Excerpt: Summary] The Italian Ministry for Environment and Territory has funded the implementation of a national Atlas on areas with risk of desertification, in order to have a preliminary tool for the correct implementation of the National Action Plan (PAN) to combat drought and desertification. The PAN has been adopted by the Italian government through the National Committed to Combat Drought and Desertification (CNLSD), established in accordance with UNCCD (ratified by Italy with law n. 170 on June 4th 1997).

A Synthesis of Information on Rapid Land-cover Change for the Period 1981–2000

  
BioScience, Vol. 55, No. 2. (01 February 2005), pp. 115-124, https://doi.org/10.1641/0006-3568(2005)055[0115:asoior]2.0.co;2

Abstract

This article presents a synthesis of what is known about areas of rapid land-cover change around the world over the past two decades, based on data compiled from remote sensing and censuses, as well as expert opinion. Asia currently has the greatest concentration of areas of rapid land-cover changes, and dryland degradation in particular. The Amazon basin remains a major hotspot of tropical deforestation. Rapid cropland increase, often associated with large-scale deforestation, is prominent in Southeast Asia. Forest degradation in Siberia, ...

Natural hazard chain research in China: A review

  
Natural Hazards In Natural Hazards, Vol. 70, No. 2. (2014), pp. 1631-1659, https://doi.org/10.1007/s11069-013-0881-x

Abstract

Most catastrophic disasters are triggered by multi-hazards that occur simultaneously or sequentially rather than singly; this can result in more severe consequences. Therefore, it is necessary to understand the occurrence, development, and transformation of hazard chains and comprehend their rules in order to predict secondary hazards. An effective action for reducing potential losses can be taken to block a hazard chain before it expands and transforms. Many studies have been conducted on hazard chains, some of which are of great significance. ...

 

Development of topsoil grain size index for monitoring desertification in arid land using remote sensing

  
International Journal of Remote Sensing, Vol. 27, No. 12. (1 June 2006), pp. 2411-2422, https://doi.org/10.1080/01431160600554363

Abstract

The grain size composition of topsoil characterizes the soil texture and other physical properties. The coarsening of topsoil grain size is a visible symbol of land degradation; thereby the change in topsoil grain size can be potentially used to monitor desertification using remote sensing. This study proposes a new index for detecting topsoil grain size composition through ground in situ soil spectral reflectance measurements and soil physical analysis in the laboratory. The proposed topsoil grain size index (GSI), which has a ...

Abrupt Shifts in Horn of Africa Hydroclimate Since the Last Glacial Maximum

  
Science, Vol. 342, No. 6160. (10 October 2013), pp. 843-846, https://doi.org/10.1126/science.1240411

Abstract

The timing and abruptness of the initiation and termination of the Early Holocene African Humid Period are a subject of ongoing debate, with direct consequences for our understanding of abrupt climate change, paleoenvironments, and early human cultural development. Here, we provide proxy evidence from the Horn of Africa region that documents abrupt transitions into and out of the African Humid Period in northeast Africa. Similar and generally synchronous abrupt transitions at other East African sites suggest that rapid shifts in hydroclimate ...

 

Hydrologic response of upland catchments to wildfires

  
Advances in Water Resources, Vol. 30, No. 10. (October 2007), pp. 2072-2086, https://doi.org/10.1016/j.advwatres.2006.10.012

Abstract

To which extent do wildfires affect runoff production, soil erosion and sediment transport in upland catchments? This transient effect is investigated here by combining data of long term precipitation, sediment yield and wildfire records with a fine resolution spatially distributed modeling approach to flow generation and surface erosion. The model accounts for changes in the structure and properties of soil and vegetation cover by combining the tube-flux approach to topographic watershed partition with a parsimonious parametrization of hydrologic processes. This model ...
