The word " piedmont " has been used with different senses, up to mean, for example, the bottom of a single slope or continental deposits into closed basins. This problem of vocabulary is increased by more conceptual other : the piedmonts look like a magical mystery place, where exists the whole solutions to questions that should be asked by the landform's evolution. We suggest in this paper to clarify the word, to do a genetic classification of the piedmonts, showing they are events born from a complex geomorphological history, and not even a geologic negative of the mountains. This study is based above all on the domain of investigations of the authors : the mediterranean zone.

The origin and dynamics of hurricane Hugo crossing Guadeloupe. During the night, on September 16 and 17, 1989, hurricane Hugo damaged the major part of the guadeloupean archipelago. It has been one of the most violent hurricanes of the 20th century in the West Indies, mainly because of the exceptional violence of its winds, some gusts having surpassed 300 km per hour. A very warm Atlantic ocean, specific surface and altitude air conditions can account for the strenght of this hurricane. Though the wind effects were extreme, those caused by the tide and swell were less important. The relatively heavy rainfalls had only small effects, because they occurred on unsaturated soils and did not reach the heights of Asian hurricanes.

Organization of world space and international flows of cereals. We start by sketching the broad features of the new geography of cereal supply and demand as it has developed over the ten last years, showing its links with the main politico-economic divisions of today's world. We then approach the problem of the existence of a world food system, before finally looking at varions cereal systems on a national and regional scale.

This article looks at geography as it was practiced and preached by an author who wrote after the Revolution, at the time of Napoleon, and under the Restauration, Conrad Malte-Brun. He was a public figure of some considerable influence who had strongly held opinions which, in part, reflected the political, scientific and ideological preoccupations of his time. The focus here is on the internal logic of his thought. His ideas on the nature of geography were often contradictory and sometimes tendentious. They, nevertheless, bear study as they had a considerable influence, although arguably not a strictly positive one, on the future of the discipline and also because they echo the concerns of " literary " or descriptive geographers — including their most modern adherents, the postmodernists.
