The aim of this study is to discuss the mechanisms that determine the occurrence of badland forms in a subhumid mountain area in the Vallcebre area, southeastern Pyrenees, that has been subjected to detailed studies on physical weathering
and vegetation dynamics. Special attention is paid to the amounts of energy available for the main geomorphic agents (rainfall, freezing, clay shrinking) as well as to the explication of the preferred occurence of badland surfaces in north facing aspects.
and seedling phases in the badland areas of the Upper Llobregat basin. The AA. sought to test the hypothesis that seed availability and seedling recruitment was not enough to guarantee colonization of these areas.

Badland landforms, created in Plio-Pleistocene clay landscapes of the Basilicata region of southern Italy, form marginal features in a semi-arid landscape dominated by the widespread cultivation of subsidised cereals. These badland features are high
relative relief forms exhibiting a high drainage density and steep slopes, with slope angles typically in excess of 35°. The economically-driven change in land use from visually striking badland areas to newly remodelled fields for agricultural use results
The aim of this study is to analyze a recent deposition-erosion alternation within a badland area in semiarid South-East Spain. Given the small size of the drainage areas involved, this alternation can be analyzed in terms of hillslope

The subject of this research, the calanchi landscape, often generally considered as badlands by non-Italian authors, is, in fact, made up of many singular landforms, each of which (calanco) corresponds to a more or less extended hydrographic unit
