The Geosite of Travertine Waterfall of El Ksiba (Morocco): A Heritage to Enhance and Preserve

Abdellah Ait Barka Jamila Rais Ahmed Barakat Elhassan Louz Samir Nadem

The travertines of El Ksiba forming cliffs with an extension of about 8 km and a variable height that can reach about thirty meters. They are developed on lacustrine limestones and conglomerates of Early Quaternary age. The results reveal the high scientific (≃0.88) and aesthetic (≃0.88) values related to the strong representativeness of the regional geological phenomena. The assessment also shows the high economic value (≃0.75) and cultral (≃0.81). In this work, we presented the strategies of valorization and protection of this heritage in the framework of rural socio-economic development through activities related to geo-tourism and geo-education.

Monitoring of forest cover dynamics in eastern area of Béni-Mellal Province using ASTER and Sentinel-2A multispectral data

Figshare (2018)

Ahmed Barakat Rida Khellouk Aafaf El Jazouli Fatima Touhami Samir Nadem

This study aimed to monitor and analyze the spatial and temporal dynamic of forest cover in Eastern area of Beni-Mellal Province (Morocco), using multispectral ASTER and Sentinel-2A MIS images acquired in 2001 and 2015, respectively. The supervised classification algorithm and NDVI were combined within a GIS environment to quantify the extent and density change of forest cover stands, i.e., Holm oak, Aleppo pine, Thya, Zea oak, Crops & others and Bare ground. The classification overall accuracy was 97.76 and 95.80% in 2001 and 2015 images, respectively. The result revealed an overall forest cover change with an increase in forested area. All species stands showed expansion at the expense of the bare ground and crops & others classes. The density maps showed a net density change with an expansion of dense forest class. The observed forest cover expansion may be due to the favourable climate in the examined period, the protection, the reforestation programs and the regeneration through clandestine cutting. These results constituted the first attempt at mapping and monitoring of forest cover change in the study region that used a remote sensing-based product. They will help authorities and forest managers for the development of sustainable forest conservation and management decisions.

The Karst Landscapes of Beni Mellal Atlas (Central Morocco): Identification for Promoting Geoconservation and Tourism

Quaestiones Geographicae (2022)

Abdellah Ait Barka Jamila Rais Ahmed Barakat Elhassan Louz Samir Nadem

Abstract The Atlas of Beni Mellal is located in the Moroccan central High Atlas, characterized by an important geo-diversity that attracts tourists every year. However, the number of visitors remains limited due to the lack of the promotion means, enhancement and mediation of this heritage. The obtained data indicate that the studied area preserves a great number of karst geosites, such as ruiniform landscapes, caves, poljes, sinkholes, Karren, shaft cave and many remarkable reliefs such as canyons and cliffs. This work concerns the inventory, the quantitative evaluation and the enhancement of the remarkable geomorphosites. The results reveal the presence of 21 sites, including six karst forms; five ruiniform landscapes and one karren form, one enviable panoramic viewpoint and five karst springs, four caves, two travertines, two waterfalls, and one structural relief geosite; canyon, and one tepee structures. However, these sites are not protected against all types of degradation, because the general public does not recognize them. These karst forms are very vulnerable, they cannot reproduce quickly, and their deterioration leads to their permanent disappearance. That is why this heritage must be the object of a particular attention of the whole community. The valorisation of these geomorphologic assets is the proposal of a number of circuits and geo-tourist routes from the perspective of local and integrated development.

Geological heritage of the Taguelft syncline (M'Goun Geopark): Inventory, assessment, and promotion for geotourism development (Central High Atlas, Morocco)

International Journal of Geoheritage and Parks (2022)

Elhassan Louz Jamila Rais Abdellah Ait Barka Samir Nadem Ahmed Barakat

The Taguelft syncline, located south of the Béni Mellal city, is one of the synclinal basins of the central High Atlas. It contains significant geological heritage that should be inventoried, valorized, and protected. The present study aimed to inventory and evaluate the syncline's geological heritage and then propose geotourism and geodidactic promotion allowing their sustainable geoconservation. This is done by applying the University of Lausanne methodology, based on the quantitative and qualitative assessment of the scientific (considered central) and additional values. Results highlight geodiversity elements with high scientific (≃0.84) and aesthetic (≃0.85) values related to the strong representativeness of the regional geological phenomena (genesis modes of magmatic bodied, tabular structure of Jbel Sgat, gabbroic intrusion of the Ait Boulmane wrinkle). The assessment also shows that the study area hosts a valuable palaeontological heritage enclosing fossil wood, ammonites, and dinosaur remains (bones and footprints). Moreover, it has underlined an important cultural and architectural interest of the tribe of Ait Sokhmane. Taken together, the diverse geological and cultural heritage identified can constitute a valuable tool for geoconservation and geotourism purposes. Due to their high touristic and educational potential, the geosites of the syncline are a preferred tourist destination for many visitors and can serve as valuable educational excursion sites for the dissemination of geosciences through different tools such as interpretation panels, digital media, leaflets, and guided tours. This exceptional geodiversity, and the rich cultural heritage, constitute a support for the development of geotourism and a tool for reinforcing local socio-cultural development. The knowledge and understanding of the different facets of the geological and cultural heritage as well as the management and planning of these resources all contribute to sustainable and developed tourism.

Inventory and assessment of geosites and geodiversity sites of the Ait Attab syncline (M’goun unesco Geopark, Morocco) to stimulate geoconservation, geotourism and sustainable development

Quaestiones Geographicae (2023)

Elhassan Louz Jamila Rais Ahmed Barakat Abdellah Ait Barka Samir Nadem

The Ait Attab syncline, in the southwestern part of the Moroccan Central High Atlas (CHA), is a vast basin characterised by an exceptional geodiversity illustrating the complete sedimentary series in the CHA. This series offers the opportunity to study regional palaeogeography, transgressive and regressive megasequences, Jurassic-Cretaceous volcanism and Atlas tectonics, and various fossils, including dinosaur footprints. The study area also harbours considerable landscape and cultural wealth that can play a significant role in sustainable geotourism and geoeducation development. To promote and protect this geoheritage wealth, the present work provides the first quantitative and qualitative inventory of geosites of interest by adopting Brilha’s (2016) method. Thus, 3 geotrails covering 8 geosites and 11 geodiversity sites have been selected. The evaluation of these sites confirms their scientific and educational importance, which helps understand the geological, tectonic and palaeogeographical evolution of the Ait Attab syncline. The tourist value of these sites is also high, explained by the high interpretative potential of the geosites and their location as a gateway to the M’Goun Unesco geopark. The degradation risk assessment showed that most of these sites have a medium risk, except for palaeontological and magmatic sites, which have a high degradation risk.
