At the regional level, in terms of water resources and exploitation or consumption
rates, apart from two very extreme and opposite situations (Libya, Israel, Tunisia,
vs. Albania, ex-Yugoslavia), there is a rather clear distinction between the North
and the South and East of the Mediterranean basin, with more favourable
situations in France, Italy, Greece, Turkey, than in Algeria, Egypt, Cyprus,
Morocco, Spain, Syria and Lebanon. In all these countries water requirements
reach a maximum when resources are at the minimum level, during the dry
summer season, which causes many quantitative and qualitative problems.
Therefore, the ratios indicated in Table 1 are based not only on the total or
potential natural resources, but also on the minimum available or regular resources
(see Table 1, Margat J., 1992).
The above classification of Mediterranean countries with regard to water
availabilities and needs should not significantly change up to the years 20002025. But discrepancies must increase between the North and the South and East
with more or less stabilized situations in the North and grave deterioration in the
South and East.
