Abstract:
Algeria, like other southern Mediterranean countries, is enduring water shortage which will
get worse over the few next years. Algeria is known as the country most severely threatened
by water stress and scarcity by early 2020. One of the important factors exacerbating this
problem is the concentration of three quarters of the inhabitants and consequently the
industrial and agricultural activities along the 1200 km coastal zone, which has led to an
increase in the pollution of the existing water resources. Droughts due to climate change and
pollution are the most important factors destabilizing the existing balance. Therefore, the
desalination of sea water can provide a solution to one of the most urgent and vital and
problems, of balancing and enhancing water resources, as the wide variation of rainfall, from
more than 2000 mm/y in the north coastal region dropping to less than 100 mm/y in the
southern Sahara, should be taken in account. Given these circumstances, we will focus on the
need for desalination, the desalination program, and also the strategy and the vision of
desalination in addition to other non-conventional water resources that might guarantee the
optimum conditions for integrated management and sustainable development
