  • there ? In discussing the first question, the AA. note the difficulty of achieving a precise definition, though it is vegetation that largely gives landscapes their colour and texture. They explore the other three questions using examples and data from Scotland, mainly

  • and deforestation). How rapidly and over what spatial scales these changes take place is considered, and then the interactions between the different factors that cause change are addressed. How this can accelerate changes and so increase landscape sensitivity
  • is considered. Lastly, whether the sensitivity of the Scottish landscape is likely to increase or decrease under predicted climate change scenarios is briefly discussed.
  • This paper starts by examining the changes that take place in the Scottish landscape and the factors that are responsible for these changes (natural disturbances, such as climate change and fire; man-made disturbances, such as sheep grazing

  • Landscape sensitivity is expressed as the ratio of the change in a system to the change in a landscape component. The larger the ratio, the greater the sensitivity. An array of drivers of landscape change is reviewed, but there is seen to be little
  • benefit in separating natural changes from human-induced changes. Changes in the systems themselves are reviewed, including the increasing evidence for 2 or more system states being possible.

  • the landscape elements comprising geodiversity requires a dynamic approach to their management and conservation, with attention to their sensitivities to changes in climate, weather patterns and land management. Geodiversity is dependent on the scale of enquiry

  • interactions with the landscape is required, in parallel with the development of numerical modelling of form and process at a variety of scales.

  • Using mainly Scottish soft coast examples, the changes associated with sensitive coastal landscapes are assessed in terms of the past timing and magnitude of changes in both sea level and sediment economy. Declining abundance of coastal sediment has
  • initiated a process of internal re-organisation that, because of an inherent sensitivity to sea level change and low thresholds for the forcing of change, fundamentally restricts future management options. The paper also attempts to show that hard rock

  • In undisturbed tropical montane rainforests massive organic layers accommodate the majority of roots and only a small fraction of roots penetrate the mineral soil. The AA. investigated the contribution of vegetation to slope stability
