Les plages du littoral de Kénitra ont connu des modifications au cours de ces quatre dernières décennies. La mise en valeur économique de certaines plages par des aménagements touristiques et l’extraction massive de sables pour les travaux d’aménagements urbains sont à l’origine d’une déstabilisation des échanges transversaux de sédiments. Ils sont...

Trees outside forests are difficult to define and often seen as troublesome in areas were major crops are grown. They are nonetheless visible everywhere in French landscapes, to the extent that they do not always get the attention they deserve. The diversity of tree structures can however supply a range of economically viable resources. Furthermore...
