Characteristics of stone covers on the surface of basalt flows in arid, northeast Jordan
This paper is concerned with attempts to identify the distinctiveness of the characteristics of stone cover as affected by lithology and slope position on a series of desert hillslopes in the late Tertiary and Quaternary basalt terrain of northeast

Boundary bunds or piles of stones ? Using farmers' practices in Bolivia to aid soil conservation
in paper were collected in field study in the Transition Zone in Tiraque Province, Cochabamba Department, Bolivia. There piles of stones and boundary bunds are traditional practices used to clear stones before the cultivation of steep stony land. Why
farmers there are reluctant to use stone-faced terraces is discussed. - (SLD)

Variation in the degree of clast exposure on stony desert slopes is examined in an area of northeast Jordan. Geological influences on the characteristics of stone mantles are modified by relative slope position. Observations that the nature
of the surface stone cover changes downslope because of the transport and accumulation of the underlying substrate are confirmed by quantitative analysis. An elliptic function is described as a means of estimating relative clast exposure from simple field

Review of why a bronze plaque in honor of Alexander von Humboldt was affixed to the north wall of the stone pyramid for Simón Bolívar on the Andean mountain Chimborazo. There von Humboldt developed his ideas on the altitudinal arrangements

This paper investigates the performance of selected soil and water conservation measures in the highlands of Ethiopia and Eritrea, namely Fanya Juu, soil/stone bund, grass strips and double ditches. The impact of these techniques on runoff, soil

Micro- and macroscale experiments which document the dynamics of salt damage to porous stone have yielded data which expose weakness in earlier interpretations. Salt damage due to crystallization pressure appears to be largely a function of solution

and mapped on the regional scale using a level of spatial resolution achievable in few places. The comparatively high mean rate of marble weathering in small town cemeteries suggests that recent acidic precipitation may be dissolving the stones throughout
