Nowadays, the international community has significant geoscience knowledge and skills necessary for providing essential resources and promoting sustainable development for the benefit of humanity . In this planetary objective, geoscientific expertise is the tool which provides important information for the knowledge of mineral, energy and biological resources, technically reliable, economically affordable and sociologically feasible. Considering the recommandations of the experts and participants of the first edition (2021), the Second International Conference on Geo-Sciences and Environment (2nd ICGSE), will be held on September 17 and 18, 2022 at the University of Mustapha STAMBOULI (Mascara, Algeria) in order to open up the debate on different scientific skills in the fields of geology, hydrology, hydrogeology and environmental sciences. Through its interdisciplinary program, this second meeting will also provide a real platform for sharing respective experiences between proven researchers, managers and decision-makers, so as to discuss the most recent concerns and to present pragmatic solutions to the environmental challenges encountered as well. The involvement of new doctoral students in useful research, oriented towards the strategic objectives of the country, namely meeting the challenge of a global and sustainable development of the national territory is strongly requested by the organizers and experts of this scientific event. The main axes selected for the 2nd CIGSE meeting deal with an innovative tendency, both in terms of exploration of natural resources (soil, water, useful deposits, biological resources, etc.) and preservation of the environmental quality of living spaces, the only guarantee of the promotion of sustainable development. These are the objectives of this second international conference on geosciences and the environment (2nd CIGSE), through which the organizers will try to involve Algerian and foreign specialists in the concerned fields in order to share their experience and serve the development and growth of our society. Hence, geologists, hydrologists, hydrogeologists and environmental science specialists interested in this issue are invited to submit their abstracts for participation either by oral communication or poster display.
