Among the named non-conventional water rsources, those obtained by desalination of sea water and brackhis waters constitute a source to supply hydric demands generated by the population as direct consumers of water and, as well, during the economic processes involved in the agriculture, industry, tourism, etc, developed on the Mediterranean territories. Moreover, the Mediterranean Water Forum considered the need to update the knowledge on the actual state of water desalination in this Region referring to uses, technologies, economic basis, energetic implications, legal framework and generated and predictable impact on the environment. All this because this knowledge was considered necessary as a starting point to carry out national decisions in order to integratedesalinated water resources into the public planning water activities in all countries of the Mediterranean Region and, in consequence, achive an integrated management of water resources. This objective will find a good supportive tool in the present REPORT ON WATER DESALINATION STATUS IN THE MEDITERRANEAN COUNTRIES 2012. The author tries to give an overview of the current state of water desalination in the Mediterranean Region. It is possible to find in it detailed information about different water desalination processes, qualitative characteristics of desalinated waters, energy requirements, environmental impacts, desalinated water demands, economy of water desalination and future tendencies. The author has chosen, as a foundation for this study, the countries with territories in the edges or in the vicinity of the Mediterranean Sea, as is the case of Jordan, although not all its desalination activities are being developed in this region. He has considered that extending the field of study will provide a complete 3 reference that allows us to know how the countries are involved in water desalination development. Being this report an initial point to achive the purposes of The Mediterranean Water Forum, its improvement would be desirable during the Forum's progress. Thus, an instrument for public opinion could come up, showing the real prospect of the increasing availability of hydric resources, by means of water desalination. A possibility, simultaneous promising and complex, which rational development might be able to turn into an effective instrument to attack the poverty in our region helping to raise the standard of living of its inhabitants. Adrián Martínez Cutillas Director Instituto Murciano de Investigación y Desarrollo Agrario y Alimentario 4 CHAPTER I WATER, A WORLD-WIDE CONCERN Water is an inorganic substance whose functions, within biological processes, cannot be done by any other substance. Therefore, it is irreplaceable and its characteristics have made it something essential in our society and have turned into a valuable possession since the early stages of humanity. Water is definitely essential in order to support every single form of life in our planet. There is an immense disparity of water distribution on a world- wide scale, not only in time, but also in space. This fact has shown that water is not an unlimited resource. Therefore, the popular belief about the “eternity of water” may be removed from our communal way of thinking. In actual fact, water scarcity is an issue increasingly discussed at the level of international organizations, individual countries and slowly but surely in citizens’ minds. Water is nowadays placed under quantitative pressure and it is also an objective for qualitative alterations, clearly affecting its different uses sustainability. Considering water quality as a management criterion for hydric resources, is related to urban development expansion, industrial activities and irrigated lands intended for agricultural purposes. Indeed, the permanent increase of water used by the activities mentioned above, being essential for social and economic development, has caused international widespread water pollution. This fact occurs with such an intensity that has placed its sustainability in serious jeopardy, not only in the present but also for future generations. There is a continuous increase of entities claiming for a rationalized water use, considering that human progress needs to include social, economic and environmental criteria to be carried out. Humankind faces the challenge to secure that millions of people surpass the poverty situation in which they are living at this moment in time. This purpose requires an enormous developmental effort that could endanger the environment. In order to avoid any negative effect it seems unavoidable, at a global level, the use of performance guidelines to guarantee the sustainable use of all natural resources. However, amidst conservation-development discussions, there is a reality that can not be avoided: the need to obtain the quantity of fresh water required by the entire world-wide population development. Water 5 demands run in parallel with societies’ progress. This is why countries involved in developing policies have to face the problem of water shortage. It has been demonstrated that in countries under arid and semi-arid climates, water deficit is related to socio-economic development, in such a way that the former can represent a serious obstacle for the latter. According to the current status of hydrologic knowledge, it seems that integrated water resources management (IWRM), including non- conventional

Vienna, 17.06.2021 _______________________ Signature Powered by TCPDF (www.tcpdf.org) Abstract Water scarcity is an increasing global issue and the need for clean drinking water is set to increase with a growing global population and the effects of climate change. Small tropical islands, when not having a natural spring, cannot rely on groundwater since the freshwater lenses are merely a very thin layer, floating above the underlying seawater. Due to changes in in sea level as an effect of climate change, these lenses are predicted to further decrease. Often the only source of drinking water on small islands is importing it in bottled form. This is not only inefficient in terms of energy footprint and price, but also creates a waste problem that these islands usually fail to adequately address.

To clarify its potential future global scale, we perform a detailed investigation of the economic feasibility of desalination development for different countries using a feasibility index (Fi) that reflects a comparison between the price of water and the cost of production. We consider both past and future time periods. For historical validation, Fi is first evaluated for nine major desalination countries; its variation is in good agreement with the actual historical development of desalination in these countries on both spatial and temporal scales.

  • A Star Is Torn—Molecular Analysis Divides the Mediterranean Population of Poli's Stellate Barnacle, Chthamalus Stellatus
    A star is torn—molecular analysis divides the Mediterranean population of Poli's stellate barnacle, Chthamalus stellatus (Cirripedia, Chtamalidae) Yaron Tikochinski1, Sharon Tamir1, Noa Simon-Blecher2, Uzi Motro3 and Yair Achituv2 1 Faculty of Marine Sciences, Ruppin Academic Center, Mikhmoret, Israel 2 The Mina & Everard Goodman Faculty of Life Sciences, Bar-Ilan University, Ramat-Gan, Israel 3 Department of Ecology, Evolution and Behavior, and the Federmann Center for the Study of Rationality, the Hebrew University of Jerusalem, Jerusalem, Israel ABSTRACT Poli's stellate barnacle, Chthamalus stellatus Poli, populates the Mediterranean Sea, the North-Eastern Atlantic coasts, and the offshore Eastern Atlantic islands. Previous studies have found apparent genetic differences between the Atlantic and the Mediter- ranean populations of C. stellatus, suggesting possible geological and oceanographic explanations for these differences. We have studied the genetic diversity of 14 popu- lations spanning from the Eastern Atlantic to the Eastern Mediterranean, using two nuclear genes sequences revealing a total of 63 polymorphic sites. Both genotype- based, haplotype-based and the novel SNP distribution population-based methods have found that these populations represent a geographic cline along the west to east localities. The differences in SNP distribution among populations further separates a major western cluster into two smaller clusters, the Eastern Atlantic and the Western Mediterranean. It also separates the major eastern cluster into two smaller clusters, the Mid-Mediterranean and Eastern Mediterranean. We suggested here environmental conditions like surface currents, water salinity and temperature as probable factors that Submitted 30 March 2021 have formed the population structure.

Ditch Street Paola, Malta PLA 1234; email: [email protected] 224, Camilleri Court, Flt 5, Il-Marlozz Street, Mellieha, Malta MLH 4100; email: [email protected] ABSTRACT During the last decade, the authors visited several stacks (Faraglione) which are satellites islets around the main circum-sicilian islands. Most of these stacks are inaccessible to the general public due to their geographical and topographical positions/inclinations. Literature is often scarce or non-existent. The current work provides a preliminary data on the floral diversity recorded during the brief expeditions between the years 2008–2018. All of these islets were observed once, so this study does not reflect all of the possibly existing species of these islets. The current study caters the Faraglione di Colombara of Ustica, Isola dei Conigli, Scoglio del Sacramento and Scoglio di Faraglione of Lampedusa, Faraglione di Tracino and Faraglione di Ficaria/indietro l’isola of Pantelleria. Another islet is the Scoglio dello Zio Gennaro, Taormina, Sicily. KEY WORDS Vegetation; satellites islets; circum-sicilian islands.

(Neuroptera Myrmeleontidae), is described from Sicily and Pantelleria. The new taxon belongs to the formicarius-group thanks to the absence of pilula axillaris in the male hind wings, the characteristics of the male genitalia and the ecological traits. Moreover, the validity of the new species is confirmed by a DNA based phylogenetic reconstruction in which it is compared with closely related taxa. A preliminary description of the third instar larva of M puni­ canus n. sp. is also given. Its habitat is the Mediterranean shrub land in which the larvae build pit-traps near shelters. Due to its ecological requirements a possible endangered status cannot be ruled out because of the anthropogenic habitat fragmentation.
