Climate change and scarcity of water resources in Algeria

Abstract

The importance of work is due to the importance of water in the continuation of human life and its great role in practicing its various activities, which concern industry, agriculture and various fields. The research methods included the increasing scarcity of water resources resulting from the decrease in the quantities available to the individual, the deterioration of the quantity and the objectives of economic and social development, thus imposing the development and definition of a water management strategy in the medium and long term. In recent years, the water scarcity crisis has increased and exacerbated due to the drought wave that the region suffers from, and it has greatly affected the region. As a result of the research, by the year 2025, a deficit of one billion cubic meters of water will be recorded. It is also possible to avoid this deficit in the hydrographic region of Constantine – Seybousse – and this is due to the dams that are in the process of being completed. In order to eliminate the shortage of water in the region, the amount of storage in dams must be increased and water desalination plants should be established in several areas in order to re-use wastewater. We can also avoid the shortage in the amount of water by building small dams and hill reservoirs, and this is to avoid siltation in large dams. Among the solutions are also increasing surface and groundwater resources, searching for new resources, dealing with losses, and improving the quality of available water.
