Ce bassin versant est à vocation agricole est menacé par le risque d’érosion hydrique qui fait partie de l’une des principales contraintes qui se pose à sa protection et à son développement. Le modèle PAP/CAR portait surtout sur l’intégration des facteurs causatifs de l’érosion hydrique, tels que la pente topographique qui traduit la morphologie et l’inclinaison des terrains et la friabilité des faciès pour déterminer la susceptibilité à l’érosion ou l’érodibilité, le type du couvert végétal ou l’occupation des sols qui traduit les systèmes de production agricole et la densité du couvert végétale qui traduit le degré de recouvrement pour déterminer le degré de protection des sols. Dans ce travail, les deux paramètres précédents ont été remplacés respectivement par le facteur topographique et par la nature des sols. Les paramètres ont été classés et intégrés selon les directives du modèle PAP/CAR. Le travail a été exécuté à travers trois approches : L’approche prédictive qui se base sur l’analyse des facteurs naturels (pente, lithologie, occupation et protection du sol) et le traitement des bases de données des cartes élaborées qui donnent des idées sur l’état de la dégradation et la vulnérabilité à l’érosion. L’approche descriptive se base sur la cartographie des différentes formes et processus de perte en sol qui se manifestent dans la zone et leurs croisement avec la carte des états de dégradation des sols pour aboutir à une carte qualitative, combinant les bases de données descriptives et prédictives, et contenant des informations complètes sur les différents aspects des phénomènes d’érosion. L’approche d’intégration qui permet la combinaison de deux approches précédentes a pour but de fournir un produit cartographique très précis qui reflète la réalité de l’état de dégradation du sol, les tendances aggravantes de l’érosion hydrique et les tendances de la régression de la dégradation, ainsi que prévoir l’évolution future de l’érosion et du paysage. Les facteurs causatifs primordiaux du risque de l’érosion hydrique, leur interaction et de leur répartition ont été définis grâce à l’analyse des corrélations. Ces résultats ont permis de détecter les facteurs et les zones nécessitant une intervention rapide et efficace pour contrecarrer l’effet de l’érosion hydrique. Les résultats peuvent constituer un document à la disposition des aménageurs pour l’aide à la décision dans les projets d’aménagement et de gestion du contrôle de l’érosion. Mots clés : PAP/CAR, érosion hydrique, facteurs causatifs, tendances, érodibilité, vulnérabilité.

The geomorphology of its landscape, as spectacular as it is diversified, gives it a rich geo-heritage that can attract investments that can initiate a socioeconomic takeoff. This heritage is often overlooked in current approaches to managing and exploiting environments. Our study focused on the identification and classification of different geosites according to the IGUL and geomorphosite assessment method modified and adapted to the context studied in order to identify their scientific, ecological and cultural values, aesthetic and economic. This study thus provided us with a database characterizing the local geodiversity represented by twenty-four inventoried geosites [1]. The results confirm that the region has a geodiversity whose importance influences not only the natural dynamics, but also the human heritage. The scientific value of geosites is, in fact, globally high and often combined with additional interests that are not negligible but poorly known and little or no exploited. Some of these sites have provided important fossil populations (lamellibranchs, ostracodes ...). The global value of the geosites made it possible to identify the most representative sites. A summary of the results proposed around a global value illustrated by maps and photos. The geosite assessment by weighting gives an overall value ranging from 0.27 to 0.87 with an average of 0.60 (Figure 1). Most hydrological, structural and geomorphological geosites have good average scientific and additional values; which reinforces their overall value. It also appears that large geosites are favored over small ones. Thus, the landscape and geomorphological characteristics make the Taounate-Mernissa region an ideal place for the development of geotourism and environmental education activities aimed at discovering links linking natural and cultural heritage. They should, therefore, be protected from irrational degradation and exploitation. In addition, the test and the criticism of the method used contribute to the development and the improvement of the bases of the adopted method in order to favor the development and the integration of the human and natural components.

Son développement se trouve ainsi confronté à des contraintes multiples, qui sont à l'origine de son incapacité à drainer des investissements de nature à initier le décollage économique. Bien que souvent accusée de manque d'atouts et de potentialités, la région de l'oriental dispose de ressources considérables qu'il conviendrait d'exploiter et de mettre en valeur notamment, une bande côtière méditerranéenne s'étalant sur environ 200 Km, présentant divers paysages côtiers allant des plages sableuses aux hautes falaises rocheuses, des zones humides et forestiers qualifiées au Maroc en tant que Sites d'Intérêt Biologique et Ecologique (SIBE), des paysages montagneux aux formations géologiques sédimentaires épaisses bien visibles sur les talus de routes et sur les versants, des volcans endormis aux multiples sites de vues panoramiques. Ces ressources sont encore non explorées ni par les chercheurs et scientifiques ni par les opérateurs économiques. Le Cap des Trois Fourches est un vaste promontoire montagneux de l'Afrique du nord qui s'avance d'une vingtaine de kilomètres dans la mer méditerranée qui pendant des siècles a constitué tout à la fois un repère et un danger pour la navigation dans la mer d'Alboran. Vu sa superficie estimée à 8 000 hectares, dont les deux tiers sont maritimes, il constitue un espace important pour les oiseaux migrateurs. La végétation en grande partie naturelle est principalement un matorral dominé par le lentisque. Sa grande qualité écologique, attestée par la diversité de ses nombreuses espèces bio-indicatrices, aussi bien les espèces protégées que les espèces d'intérêt commercial, ainsi que par la diversité des habitats (prairies, grottes, substrat rocheux, etc.). Ce lieu sauvage réputé pour ses paysages sublimes, ses grottes et ses nombreuses plages, la plupart du temps désertes. C'est pour toutes ces qualités qu'il a suscité depuis quelques années un intérêt grandissant malgré la faible fréquentation des touristes, mais paradoxalement, cet aspect sauvage et authentique en fait de lui un espace enjeux ou les mutations de fond de la société entraînent des répercussions fondamentales. La valeur patrimoniale (géologique et écologique…) du cap appelle plusieurs acteurs dans les domaines de l'environnement, l'aménagement, l'agriculture, la pêche, le tourisme, pour une mobilisation pour sa préservation et son aménagement d'une manière rationnelle. Ceci peut être envisagée via la promotion d'actions de développement durable, respectueuses des valeurs écologiques et intégrant les dimensions économique, environnementale et sociale. La mise en valeur touristique du patrimoine naturel du cap des trois fourches demeure un champ fertile

The landslides that have occurred in recent decades and six predisposing factors were mapped for applying method to assess landslides hazard. The method is based on the principle of fuzzy logic, it consists to determining the information value that reflects the probability space, determining the temporally probability, then determining the fuzzy memberships and finally the fuzzy superposition with a gamma equal to 0,9. The obtained results are critically compared and validated through the construction of the success rates curves and the computation of the corresponding Area Under Curves. The vulnerability of elements exposed to this risk was estimated by a method based on indices that quantify the damages according to four criteria, personal injury, structural damage, functional loss and ignorance of the hazard by population. These indices were represented cartographically. Total vulnerability is obtained by the overlay of four maps and the summation indices. The combination of the two techniques leads to a hierarchy of the field according the landslides risk. Areas where the risk is highest cover 22%, 21% has medium risk and 47 % are only slightly threatened. Through this study, it was observed that the risk areas are not necessarily that contains a large number of slides or a high degree of susceptibility but it is those who expose a large number of issues.
