Water resources are a key issue for many Mediterranean countries, except perhaps in the more water-rich Balkans. The Blue Plan estimates that eight of the southern and eastern countries are using more than 50% of their renewable water resources, and two of them (the Palestinian Territories and Libya) are already overexploiting their renewable water resources. Moreover, this trend is expected to continue in the future.
Essential for life
Freshwater ecosystems contain less than 0.01% of the Earth's water, but account for a much larger percentage of the global biodiversity. Thus, of the species assessed, 547 amphibians, crabs, freshwater fishes, dragonflies, reptiles and mammals are dependant on freshwater habitats for at least some part of their life cycle. The fact that 38% of these species are threatened gives an indication of the worrying status of Mediterranean wetlands and rivers.
