|Title:||CHANGEMENTS CLIMATIQUES ET ACTIVITES ANTHROPIQUES: IMPACTS SUR LES AQUIFERES COTIERS EN ALGERIE|
|Keywords:||Coastal aquifers, diagnosis, pressures, trends, strategy|
|Abstract:||The status of Algerian coastal aquifers and recent developments affecting them, show that the large deficits observed (on the basis of the confrontation-resource needs) will widen increasingly; in addition to the effects of climate changes which are significantly felt with a rainfall deficit estimated at around 30%. Moreover, to the risk of exhaustion is superimposed a qualitative resource degradation, mainly the risk of seawater intrusion and anthropogenic pollution related to agricultural and industrial activities. To overcome this, an ambitious strategy was developed. It materialized by a set of projects and actions, especially the mobilization of non-conventional resources such as desalination of sea water (950 hm3 / year by 2030) and reuse of wastewater (where 251stations will produce 1200 hm3 / year in 2030). It nevertheless remains that a rigorous policy of demand management is needed, this through: (i) scientific development (monitoring, modeling, information systems and decision support), (ii ) adequate management based on financial mechanisms in order to avoid waste, (iii) sensitization and communication policy.|
