The city of El Jebha, Morocco, and its surroundings have always been affected by instability and slope failure, both natural and man-made. The Neogene conglomeratic clay formations, which form most of the city of Constantine, are extremely sensitive to the presence of water, which makes them susceptible to landslides. Therefore, to preserve the env...

Mapping lithological units of an area using remote sensing data can be broadly grouped into pixel-based (PBIA), sub-pixel based (SPBIA) and object-based (GEOBIA) image analysis approaches. Since it is not only the datasets adequacy but also the correct classification selection that influences the lithological mapping. This research is intended to a...
The Paleozoic Tichka massif in the Western High Atlas constitutes a key sector to understand the transition between the Atlas and Anti-Atlas domains. This massif was intruded by several granitoids in which the important plutonic complex Tichka emplaced within Paleozoic rock units was subjected to syn- to late-emplacement deformation (D3) resulting...
Morocco is considered one of the most ambitious countries in terms of adopting strategies that promote renewable energy and energy efficiency. Despite its lack of oil resources, which makes it the greatest energy importer in the region, Morocco has been following a sustainable plan starting 2009, prioritizing the development of renewable energy sou...
For most developing countries, using renewable energy sources is always conditioned by government's fear and reluctance towards the high cost and the complexity of technology needed. One of the greatest problems to face, once decided to get into the eco-friendly source, is the variability of energy potential in the globe generally and the region sp...
