This paper analyses the statistical parameters of the grain size distributions of soils of South Tunisia where different landscapes coexist, with a graduation from semi-arid to arid and including both natural surfaces and agricultural or pastoral
évaluation du potentiel agroécologique des sols de la zone semi-aride en se basant sur des critères agronomiques. Les résultats des analyses pédologiques montrent une bonne fertilité des sols, ce qui permet d'envisager le développement de pratiques

A calcrete profile developed on the top of a calcareous consolidated dune located in a coastal area of NE Tunisia (semi-arid climate) was studied with the aim to investigate the behavior of the chemical elements (rare earth elements—REE—and other
The aim of this paper is to provide an accurate estimation of catchment-wide erosion rates for a semi-arid mountainous region belonging to the Betic Cordillera. Modern erosion rates were estimated based on measurements of checkdam sedimentation

that it is unique. Two policies are considered : decreasing urban unemployment benefits and subsidizing urban employment. Decreasing the unemployment benefit in the city creates urban jobs and reduces rural–urban migration since new migrants have to spend some time
unemployed before they can find a job in the city. Raising employment subsidies increases urban employment but may also increase urban unemployment because it triggers more rural–urban migration.

This edited volume brings together a range of international scholarship on cities, urbanization, and urban culture. The format of the collection involves short essays that explore such themes as new forms of political mobilization, the effects
of economic instability, the political ecology of urban nature, and the presence of collective memory. Cultural aspects of urban change are considered, including the work of artists and film makers who have critically engaged with processes of urban change
Bunkerology - a case study in the theory and practice of urban exploration
Internet ; Site preservation ; Town ; Urban environment
The paper reviews existing academic interpretations of urban exploration and argues that focus on identifying the emancipatory dimension of this practice has failed to account for the orientation evident in the study of accounts of exploration
of Cold War bunkers posted on urban exploration Internet forums.

This study aims to test a semi-quantitative method of landslide vulnerability assessment in relation to population and road distribution, using an integrated multi-criteria method. This approach is focused on a case study from the Prahova Sub
, proneness of the slopes to landslides and increase of the anthropic impact during the last decades. The results are discussed. As a general conclusion, the semi-quantitative multi-criteria analytic hierarchy analysis is most sensitive to the input data.
