There are incentive indications that the growth of human population, the increasing use and abuse of natural resources combined with climate changes (probably due to anthropic pollution, to some extent) exert a considerable stress on closed (or semi-enclosed) seas and lakes.
In many regions of the world, marine and lacustrine hydrosystems are (or have been) the object of severe or fatal alterations, from changes in regional hydrological regimes and/or modifications of the quantity or the quality of water resources associated with (natural or man-made) land reclamation, deterioration of geochemical balances (increased salinity, oxygen's depletion... ), mutations of ecosystems (eutrophication, dramatic decrease in biological diversity... ) to geological disturbances and to the socio-economic perturbations which have been the consequences, or may be in the near future.
Seas and lakes are dying all over the world and some may be regarded as already dead and there is an urgent need to try to understand how this is happening and identify the causes of the observed mutations, weighing the relative effects of climatic evolution and anthropic interferences.
Examples of critical environmental regions which might be of interest are : Aral Sea ; Caspian Sea ; Balkhash Lake (Kazakhstan) ; Sarykamysh Lake, Kara Bogaz-Gol Bay (Turkmenistan) ; Issyk-Kul Lake (Kyrghyzstan) ; Dead Sea, Lake Kinneret (Israël) ; Erie Lake, Great Salt Lake, Mono Lake, Salton Sea, Pyramid Lake, Tulare Lake (USA) ; Akrotiri (Cyprus) ; Lobnur Lake, Qinghai Hu Lake (China) ; Lake Corangamite, Australian Crater Lakes, Lake Eyre (Australia) ; Chad Lake ; Lake Elmenteita, Lake Naivasha (Kenya) ; Lake Biwa, Seto Inland Sea (Japan) ; Black Sea and Azov Sea ; Lake Turkana, (Ethiopia/Kenya) ; Lake Natron (Tanzania) ; Lake Poopo, Titicaca Lake (Bolivia) ; Mar Chiquita (Argentina) ; Nestos Lakes (Greece) ; Uluabat Lake (Turkey) ; Victoria Lake.
Considering the widespread geographical diversity of the sites of interest - some of which are (or were until recently) quite remote - and the difficulty to identify from the outset the most qualified participants, the meeting is organized in two stages : (i) the Colloquium, May 5th to 7th which, following the tradition of the Liège Colloquia, will be an open forum, consisting of a large, well-documented, poster display (which will stay open until the end of the week) and short oral presentations of the posters, (ii) the ARW, May 8th to May 10th, assembling a small group of invited active and eminent scientists from various countries and all disciplines (mathematical modeling, physics, chemistry, biology, geology, socio-economy and human sciences, including historical studies of past events and ancient civilizations) to foster a mutually beneficial exchange of information, opening on to a survey of major recent discoveries, essential mechanisms, impelling question marks and valuable recommendations for future research and management decisions.
