Climate change is having short-and long-term impacts on surface and groundwater in the northern part of the African continent. This has led to a wide range of consequences that have added pressure on the groundwater systems in this part of the world. Among such pressures, we can cite the mal-distribution and the irregularity of precipitation and ice, flooding, evaporitic sediments input by the drainage net, water degradation, mud stagnation in dams, dead tranche, drought, decreasing of the natural recharge and increasing of the groundwater abstraction, conflict between trans-boundary waters, desertification, imbalance between the regions, migration, revolution, socio-economic imbalance, etc. Actually, watermonitoring networks indicate noticeable hydrogeologic variations and a rise of the groundwater salinity. It was confirmed by the geochemical analysis of water resources that showed scattered data between the northern part characterized by low mineralized groundwater (TDS ranging 0.4-3 g/l) and the southern area where the salinity ranges from 2.5 to 90 g/l. The obtained values are far above the permissible limits for both human consumption, agricultural and tourist activities. These effects, when compounded, are anticipated to worsen the situation and to constitute veritable threats for social and economic development in these regions of North Africa (Morocco, Algeria, Tunisia, Libya, Egypt, etc.). The potential solutions consist of taking urgent to utilize the intelligent technology (bio and nano-technology), policies relevant policies to manage water resources, and the engagement of private, civil, and international sectors if a major crisis is to be averted (collective effort).

“…They could be considered as conditioning factors in the phenomenon prediction. In our research, both predisposition and triggering factors were selected among those most commonly used in landslide susceptibility assessment [31]. The data source used in this study comes from Landsat 7 Enhanced Thematic Mapper Plus (ETM+) images, aerial photographs, geologic and topographic maps, etc.…”

The purpose of the present study was to compare the prediction performances of three statistical methods, namely, information value (IV), weight of evidence (WoE) and frequency ratio (FR), for landslide susceptibility mapping (LSM) at the east of Constantine region. A detailed landslide inventory of the study area with a total of 81 landslide locations was compiled from aerial photographs, satellite images and field surveys. This landslide inventory was randomly split into a testing dataset (70%) for training the models, and the remaining (30%) was used for validation purpose. Nine landslide-related factors such as slope gradient, slope aspect, elevation, distance to streams, lithology, distance to lineaments, precipitation, Normalized Difference Vegetation Index (NDVI) and stream density were used in the landslide susceptibility analyses. The inventory was adopted to analyse the spatial relationship between these landslide factors and landslide occurrences. Based on IV, WoE and FR approaches, three landslide susceptibility zonation maps were categorized, namely, “very high, high, moderate, low, and very low”. The results were compared and validated by computing area under Road the receiver operating characteristic (ROC) curve (AUC). From the statistics, it is noted that prediction scores of the FR, IV and WoE models are relatively similar with 73.32%, 73.95% and 79.07%, respectively. However, the map, obtained using the WoE technique, was experienced to be more suitable for the study area. Based on the results, the produced LSM can serve as a reference for planning and decision-making regarding the general use of the land.

“…Terrain instabilities with multiple shapes of natural or anthropogenic origins often cause significant damages to facilities (Mouici et al 2017;Manchar et al 2018;Karim et al 2019) and disrupt the socio-economic development of mountainous areas Tamani et al 2019). In Northern Algeria, many regions are affected by instabilities (Hadji et al 2017a;Mahdadi et al 2018). Because of the disorder they cause in the road network (Achour et al 2017;Dahoua et al 2017a;, agglomerations (Hadji et al 2014;Hadji et al 2016;Hamed et al 2017), and open-pit mining (Gadri et al 2015) added to human losses (Mokadem et al 2016;Hadji et al 2017b), many researchers are working on this problem (Achour et al 2018).…”

Trepça mine was opened by traverbank from the First Tunnel and then through the central well to the depths of XI-th horizont (from 760m up to 12m), 11 horizonts were developed with vertical distance of 60m, while in the above part of the mines, between quotes 760m and 610m, 4 horizonts are developed with vertical spacing every 35m. The mine is about 750m deep and wide 2500m with an average of 20 mining bodies, which, in the horizontal cut have a size of 300 to 3000m2. In this paper it was analyzed the stability of the security plates of the ore in the "Trepça" mine in Stantërg, which are formed in ore during primary use. In the general part, will be given knowledge from the geological aspect of the mine and detailed knowledge on the exploitation systems of the mineral resource.
