      The complex badland landscape at Tabernas results from a combination of relief amplitude generated by tectonic uplift since the Pliocene and reactivated several times during the Pleistocene, the properties of the Tortonian sedimentary rocks and a predominantly arid climate. The landscape is dominated by deep incision of the main river systems, which continues in part of the headwater tributaries, and characterized by contrasting slope morphologies and a variety of microecosystems. The Tabernas badlands exhibit a diversity of landforms resulting from the combination of multi-age soil surface components that allow a variety of processes to operate at different rates. These are dominated by rilling and shallow mass movements on south-facing hillslopes. On old surfaces and north-facing hillslopes, where biological components are present, overland flow with variable infiltration capacity and low erosion rates prevail. Incision in the gully bottoms occurs in the most active areas.

    • Mainstreaming sustainable development - A case study: Ashton Hayes is going carbon neutral

      Alexander, Roy; Hope, Max; Degg, Martin; University of Chester (SAGE, 2007-02-01)
      This article discusses a case study of Ashton Hayes in Cheshire. In November 2005, the parish council of Ashton Hayes voted to try to become England's first carbon neutral village. The process of project development and implementation are discussed and some general conclusions from this experience are drawn. Ashton Hayes provides an interesting case study of a community-led attempt to bring sustainable development into the mainstream.
    • Slope–channel coupling between pipes, gullies and tributary channels in the Mocatán catchment badlands, Southeast Spain

      Faulkner, Hazel; Alexander, Roy; Zukowskyj, Paul; University of Middlesex ; University of Chester ; University of Hertforshire (Wiley, 2007-10-18)
      This article attempts to develop a conceptual model of the way geologic, topographic, material property and ecological factors combine to explain the complex geomorphological evolution of the Mocatán catchment badlands in Almería, Spain.

    • Variations in soil dispersivity across a gully head displaying shallow subsurface pipes, and the role of shallow pipes in rill initiation

      Faulkner, Hazel; Alexander, Roy; Teeuw, Richard; Zukowskyj, Paul (John Wiley & Sons, 2004-08-20)
      This article discusses how three-dimensional patterns of geochemistry and sediment size can be related to hydraulic gradients in the local marl bedrock of Almería in southern Spain.
