The responsibility for planning and management of coastal areas belongs to the local, regional and national governments. However, due to the European dimension of the problems involved, as well as the significant influence of European policies and actions on the development of the coastal zones, it is the opinion of the European institutions that the Community also has a role to play in promoting a more integrated and sustainable approach to management of the European coastal zones. For this reason, in 1995, the European Commission launched a demonstration programme on Integrated Coastal Zone Management. This programme, a joint initiative of

from, the demonstration projects will also be widely diffused through printed materials, the Internet and at coherence and public fora. The results of the demonstration projects are also intended to help guide the Commission in development of a proposal for possible further Community action or legislation in the area of Integrated Coastal Zone Management. At the end of 1998, the Commission will launch a European-wide discussion about the appropriate steps for the future. Although the Commission's demonstration programme in ICZM is centered around its selected demonstration projects, these projects clearly cannot represent all conditions or factors related to ICZM in Europe.

The programme is centered around a set of some 30 demonstration projects funded by a variety of Community instruments inc1uding LIFE, TERRA and PHARE. Located in a variety of physical, cultural and economic settings, each of these projects is taking an innovation approach to some aspect of ICZM. The successes and failures of these projects will serve to illustrate the conditions necessary to implement

The practical cases and perspectives discussed in this publication illustrate the particular problems and challenges posed by the artificial wetlands in the countries of the E.U. and our near neighbors. As such, they provide valuable insight into the mechanisms of ICZM in such areas; this publication is thus very pertinent to the work of the demonstration programme and will forrn a valuable contribution to our efforts.

true that the outlook for these sights used to be bleak and there was a clear trend toward gradually abandoning them. Nonetheless, a tour of the Mediterranean coast in the compan y of the collaborators of this project, is enough to see how some of these problems have been successfully addressed and how the main problems have been identified. AII these cases were discussed in a seminar held June-1997 at UNESCO headquarters in Paris. The general conclusions of the seminar are included in this volume.

This is how salt has been produced in the European solar saltworks since the antiquity, using either sea-water (e.g., on the Mediterranean or Atlantic coasts) or brine from salt-springs (e.g., in the Iberian inland). Certainly, before real saltworks have been developed and used to produce salt, salt had been worked in a more primitive way, such as the primitive saltems

This is why, some centuries ago, Europeans, as other peoples also did in other parts of the world, struggled to obtain salt or to augment their salt production. As the centuries went by, many things change over the salt. Especially as to its importance for life. Salt has stopped to be as necessary as it used to be in food conservation. In the meantime, it had been almost totally replaced by modem technological inventions such as refrigerators. However, despite of the

level was much lower than it is nowadays. This still applies to flat estuaries of rivers such as the Nile, the Rh贸ne and the Euphrates, where the installation of new saltworks has been proven extremely awkward. In climatologically favoured regions, with high temperatures and low precipitation during the salt production period, salt crystallises by simple evaporation of the water. In Europe, this can take place on the part of the Atlantic coast south of the 48th parallel, in the Mediterranean and the Black Sea, as well as some dry and warm inland areas endowed with saline springs, like in Spain. With the exception ofthis last country, practically all solar saltworks are situated on the coast and use sea-water.

tory. Herodotus, the father of History, was the first to have vis-

Even nowadays, salt-cultivation means maintaining saltworks in use. lt is highly unlikely, however, that ancient Greeks were aware of these notions, as natural sea-salt was enough to cover their needs. There is no doubt that ancient salt was sea-salt. This does not only apply to classical Greece, even that of the Protocycladic period (ea. 5,000 years ago), where salt occurred naturally, but also ancient Rome. The main sources of salt during the Republic or even during the Imperial era were the artificial saltworks by the estuary of the river Tiber. According to Titus Livius, it

the Romans already constituted a technical progress. In fact, the first description of relatively advanced saltworks dates from the 5th century A.D. And it is only since the 5th or 6th century that real artificial systems for salt crystallisation have come into existence and, at the same time, salt has been harvested almost everywhere with the help of special tools. Soon after, also in the Early Middle Ages, the method of the successive evaporation basins was introduced, long before the Wh century. This method, still in use today, is distinguished in that of periodical (intermittent) crystallisation and that of continuous crystallisation.

His works take us on a systematic guided tour of the historical map of his world, inc\uding some vital information about the geography and genesis of salt. Five centuries later, Strabo shared his ideas re-describing and amplifying the salt-making world of the Mediterranean. Then, Aristotle, the Greek philosopher, who has influenced more than any other what is called "westem" or "European" thinking, not only he described the different methods of salt-making in the world that was known to him in a very systematic way, but he also developed some important theories on the origin and the essence of salt.

This combination permits population growth for the few species that specialise in hostile, extreme environments and leads , by the same token, to the growing diversity of organisms depending on the former for their diet.

Many Mediterranean saltworks belong to larger wetland zones protected by the international Ramsar Convention and host species protected by other European and intemational agreements on nature conservation like the Directive of the European Council on bird protection and, more recently, that on the conservation of natural habitats of wild fauna and flora.

This, for obvious reasons, goes hand-inhand with the intensification of the salt production in their expanses, related to full-mechanisation of the production and the subsequent loss of habitats for the hosted species, especially those using the saltworks as a nesting place.

As mentioned above, many saltworks have been recognised and function as natural parks. However, there are others that lack this recognition. Yet, there are saltworks that have been abandoned and have lost those biological characteristics that make them interesting as saline ecosystems. This situation is reversible only under the condition that salt cultivation is again re-established to a certain extent. Conserving, as well as upgrading the saltworks from the architectural, ethnological, cultural and landscape viewpoints should become one of the priorities. Such upgrading actions, which have been scarcely identified in the broader Mediterranean, should be further encouraged and supported, as it has been

Atlantic salinas produced 220,000 ton s of coarse salt yearly.

THE GUÉRANDE EXPERIENCE

Since those times, the production has fallen and many former areas have unfortunately been abandoned or transformed for other activities (aquaculture, constructions, roads ...). Some

tant to remember that the salt is harvested every day if the weather al!ows it. In winter, the reservoirs (vasieres) are kept after. During the spring, the salina is cleaned; the silt is raked out and the smal! dikes (ponts) are reinforced. The salinas need a constant maintenance and every 25 years they have to be restored in order to work and to produce in an optimum way. The young salters have taken up al! these activities and can now teach them to the newcomers. When the first rains fal! in autumn and the crystallisation process is stopped the harvested salt is brought from the salinas into the co-operative to be stored.

The harvest of the coarse, slightly grey salt, takes place in summer. The salter walks on the narrow dikes as the clay bottoms are very soft and will not stand his weight. The traditional salt-scrape (las) is the main tool. Ifthe weather is favourable, the harvest is done daily. Photo: Hjalmar DAHM

As to answer a growing demand, some of the salt is dried and mil!ed, sometimes added with algae or aromatic herbs. Thanks to numerous, regular and independent controls, the salt from Guérande has obtained several quality « labels » (Label Rouge, Nature & Progres). A co-operation with the World Wide Fund for Nature (WWF) has lead to a special packaging based on the aspects of protection of wetlands. The majority of the salters (90%) are members of the cooperative. The co-operative has its own distribution, but can also work together with other companies in order to sel! the salt

Therefore, some years ago the salters' co-operative and the French ornithological society (L.P.O.) created, together with other organisations, the Maison du Se/o This « salt-house» is now one of the three « meeting-points» in the salt-marshes. A permanent exhibition has been built up with optional guided walks that attract several thousands of visitors, especially in summer, and groups of school-children in spring. The main subject of the exhibition « Salt and environment» explains the economy of local salt production and the ecology of saltmarshes.

The guided walks in the area are organised by the salters themselves. This gives a high quality guiding and the visitors are pleased to be in contact with a professional salter. Some guided walks are on specific themes: birds, plant-life etc. Photo: Hjalmar DAHM

The Guérande salinas: a model for other areas? Many different, but some-how linked reasons have allowed the Guérande salinas to get well-known. In France, thanks to an important marketing of the salt, the product is now known and can be purchased all over the country. The training-course attracts more and more young people from all over the country, and the rejuvenation explains the recent

In recent years, fierce competition has become a threat to the industry. New salt works, using salt from mines and energy surpluses from other industries, or electricity generating stations that produce salt as a secondary product, are threatening the very existence of most of our coastal salt pans. Spain has a surplus of salt and export prices would be too low to maintain the traditional salt industry if a large proportion of salt production were exported. If domestic prices dropped as well, even more salt works would close down. Low-priced imports

The importance of this habitat is well documented by publications of authors around the world, from Europe to South Africa and from India to North America. In Portugal significant proportions of the national, and European, breeding populations of a selection of species, namely Blackwinged Stilt (Himantopus himantopus), Avocet (Recurvirostra avosetta), Kentish Plover (Charadrius alexandrinus) and Little Tern (Sterna albifrons), depend on salinas. At the Aveiro region the 1997 survey revealed ea, 100 pairs ofLittle Tern, ofwhich 90 % where in active salinas, 2 pairs of Cornmon Tern (Sterna hirundo), 65 pairs ofBlack-winged Stilt, with 69 % in active salinas and 120 pairs of Kentish Plover, of

Amongst the many and very important functions performed by the wetlands, hydrogeologic, climatic, economic etc., the biological function assumes a particular character that in itself makes understandable the reason for which these areas have been recognized by these organizations as community's heritage, not only in the state of geographic relevance but also in the intemational community. The continuing reduction of these breeding grounds, the poaching, and environmental degradation causes a forced lengthening of the distances between rest stops of migrating birds, by as much as hundreds of kilometers, causing their death due to exhaustion and enfeeblement, consequently reducing this omithic population. The longer this goes on, in the worst cases it could also provoke extinction of the species. If you think that in the course of the 20th century, in the Mediterranean area, the wetlands have been reduced by 50% as a result of human intervention. In Italy, comparing with the almost 3 million hectares of wetlands that existed in the period after the fall of the Roman Empire, today these do not

The Sto Caterina Pond The S. Caterina pond even if located on the Sardinian mainland, belongs to the municipality of S. Antioco and represents a very important geologic appendix in arder to understand the natural environment of the S. Antioco island. The pond can be easily reached through crassing the isthmus existing between S. Antioco island and Sardinia; In the '60s the S. Caterina pond has been entrusted to the State Monopoly in arder to be exploited as saltworks; this caused a quick degradation ofthe typical flora. However it is stilI possible to look with delight at countless flamingo colonies while they slowly move in the shalIow waters, at sea-gulIs and, where the bottom is dry, at crowds of kentish plovers running very fast and then stop suddenly. Who would like to get a better knowledge of the nature of these marshes, should drive on to the near vilIage G. Giovanni Suergiu and then, on the right, take the road running southward and reach Porto Pino. On this way the visitar can look at two ponds, Porto Botte and Is Brebeis and enjoy the marvelIous sight of unparalIeled beauty of the long beach at Porto Pino with its sand dunes and very cIear sea, rich in shelIs even of remarkable size. The natural life in this saline environment shows very interesting features.

To prevent any kind of illegal trade with salt the Republic of Venice at the middle of the fifteenth century initialized and supported the foundation of new town of Pag, placed at the entrance of salt bay (so called "Valle di saline"), where it was possible to control all the ships that were going out of bay. Only from Pag salt pan s the Republic had income of 60 to 80, or even 150 thousands ducats on year (it is about 200 to 500 kilos of gold), which made approximately ten percent of the whole state income. Just for illustration, the famous Palazzo Ducale (Doge palace) in Venice might had cost about half a million ducats (less than ten years profit from Pag salt pans).

The grid system of the saltworks, based on the dykes between pools, is a model of human intervention that is of extraordinary scenic interest. In recent years it has proved to be first-class cultural and tourist resource. Even individually, there are many interesting elements from a heritage point of view: old, animal-driven water wheels and elevators, salt warehouse, water circulation system with its inlets and mouths, traditional windmills, the wheelhouses of old fishing boats, watchtowers, wells and archaeological sites. The importance of the Ibiza-Forrnentera saltworks also lies in its diversity and in the fact that it is a perfect laboratory for conserving, studying and improving habitats of this kind.

The natural environment and the saltworks The salt pans are located on either side of the Els Freus channel that runs between Ibiza and Forrnentera. Altogether, they cover an area of approximately 435 ha., more than 70% of which are on the island of Ibiza. The salt pans of Ibiza are situated on what were once coastal lagoons that have be en adapted to salt production and used since the times of Carthage.

Access to the area of the pools would have to be organised so as to avoid disturbing the bird-life and salt production as far as possible.

The existing heritage is more than sufficient for establishing an important cultural and eco-tourism industry. New, sustainable tourist products could be offered, based on the potential of the salt pans landscape. Support infrastructure for this kind of action would be provided by the many elements that already exist in the area, which would, moreover, channel the current scattered tourist activities. The Plan proposes: creating a salt museum and aSes Salines visitors centre in the village ofSa Canal (Ibiza). Visitors centres would channel the flows ofvisitors to the area and could plan thematic routes in the wetlands area. In Forrnentera, the visitors centre is planned for the abandoned saltworks of Ferrer. The proposal also include introducing algae production. Sightseeing would be based on restoring heritage sites in areas of low impact but with spectacular landscapes. Design, establish and sign post a basic network of trails,

THE CANARY ISLAND SALT PANS RECOVERY PLAN

East coast ofLanzarote and for extending the famous Salinas de Janubio (Janubio Salt Pans), the largest and most spectacular salt pans in the Canary Islands. The enormous variation in the coastline of the Islands and the ingenuity of the local population have generated a variety of types of salt works that can be divided into four, well-defined models:

The Canary Islands salt pans The native inhabitants of the islands were known to have harvested salt from coastal pools. The original system developed over time into one of the most curious models of primitive salt pans anywhere, an example of which still survives on the coast of Ba単aderos (Gran Canaria). There are also examples that have clearly been based on the Mediterranean model, along the lines ofthe ones that can still be found on the Lebanese coast. The Salinas del Rio - Rio Salt Pans - (Lanzarote) are a prime example of these. Reports of these salt pans go back to the earIy 14th century and they stiII form a beautiful landscape and a first -class bird sanctuary. There have been two clear periods of expansion in the

New refrigeration technology, along with the decline of the curing industry associated with the Saharan bank fishing grounds, improved transport and the effects tourism has had on pattems of land use on the coast and the work force have all plunged the Canary Island salt industry into an inexorable process of depression. Of nearly sixty salt works that used to exist in the Canary Islands, only nine continue to operate, although many of the other salt pans survive as abandoned sites of great scenic, natural and architectural interest that could be maintained and recovered. Unlike the extensive salt works of the mainland, with their large crystallising pans in which the salt is harvested once ayear, the salt works ofthe Canary Islands are much

economy (BERNAUS,1986; BOATO-SIGNORA, 1985; DONATI,1984). In addition to the traditional fishing activity, the unusual activity of "vallicultura" is also practised in these areas. "Vallicultura" is used for a particular type of extensive aquaculture with the scope of breeding species of fish that are euryhaline, and adaptable to differing levels of salinity in particular. These include the European Gilthead (Sparus auratus), the European Bass, (Dicentrarchus

labrax), the European

Eel (Anguilla anguilla ) and the Mugiloidei including the Flathead Grey Mullet (Mugil cephalus), the Thicklip Grey Mullet (Chelon labrosus), the Thinlip Grey Mullet (Liza ramada), the Golden Grey Mullet (Liza aurata) and the Leaping Grey Mullet (Liza saliens) (AA.VV., 1984a;RAvAGNAN,1978). These species are definied as "euryhaline" due to their ability to adapt to a wide range of environmental conditions, and they come frorn breeding areas that are often located at a considerable distance from the coast.

These areas have given risen to a deep-rooted culture that as unique and homogeneous ethnographic elements (BULLO, 1940; NARDo,1871; RALLO,1992a; RALLO,1996). Fishing has mainly developed through the fishing centres of Grado, Marano, Caorle, Burano, Venice, Pellestrina, Chioggia, Goro, Gorino and Comacchio (BULLO,1891; DE MARCHESETTI, 1882; KRISCH,1900; ARCA'et alii, 1992).

Man made use of this natural migratory event of the eurytrophic species by adapting several stretches of the lagoon areas with special works and structures. It is comon opinion to state a fact that fishing and hunting were developed not far from the "Rivoalto islands" (the actual Venice) even before the creation of permanent human settlements; GALLlCCIOLI (1795) wrote in his essay: "Fino dai tempi piú remoti eranvi in questi estuari certi chiusi d'acqua destina ti principalmente alla pesca e uccellagione; i vecchi le appellavano semplicemente acque, ma le recenti etá le dicono valli (= Since ancient times there were in these estuaries some enclosed basins destinated for fishing and bird-hunting: the old generations used to call them acque, but the new ones call them valli)".

The simple use of the saltwater wetland zones in question through "vallicoltura", makes for an annual production rate between 70 and 150 kglha of "white" fish, that is the eurytropic species used in classical "vallicoltura" (RALLO,1987). Here it must be emphasised that the natural environment represented by the coastal saltwater wetland zones, can well be considered a true model of integrated management resulting from a centuries-old ethnographic-cultural situation(KIRK, 1987; RALLo,1996). Every "valle" is a separate and specialized geographical and hydrodynamical unit. In fact, it consists, as a

"valle" as a geographical unit remarking, in a legal point of view, the components that we've mentioned above. From the point of view of nature, it is clear that the "valli da pesca" fish-farming

reserves at present are a fundamental

habitat for various populations of water birds present in the northwestem Adriatic regions. In the entire system of the northern Adriatic coastal wetlands, contingents of wintering water birds can be found first and foremost in the "valli da pesca" fish-farming reserves (Fig. 10). If detailed analyses are done on the data on wintering supplied by the periodical census caried out by the r.W.R.B. (International Waterfowl and Wetlands Research Bureau) and coordinated for Italy by the LN.B.S. (National Institute of BiFig. 7 - "Buseno'' of a "valle".

"Vallicoltura" then, referring to the northern Adriatic use of portions of lagoons known as "valli da pesca" or fishfarming reserves, is an interesting form of wetland management. It involves unusual ethnographic, historical, cultural and environmental elements.

Fig. 8 - "Canale sbregavalle" ofValle Averto in the Ven ice Lagoon

As for the main species of nesting water birds, it can be seen that the "valli da pesca" are also essential for several populations of Ardeidae (FASOLA-BARBIERI-PRlGIONl-BOGLIANI, 1981; heron colonies (Fig. 11).

b. Quality of the waters : fresh-waters (form the inland) and salt waters (from the lagoon), which are extremely important for the "valle" system are becoming more and more polluted, due to the industrial emissions ( organoChlorinated, heavy metals etc., from the industrial areas

there is a loss of the identity of the work in

the "valle". A job like "capovalle"(chief of the valle), "capopesca" (fishing chief), "capocaccia" (hunting chief) and "valles ano" (skilled worker of the valle) is today less and less considered as a rewarding job due to the other offers of the industrial work ( Venezia-Mestre-Marghera area, for instance). The know-how, which a "valle" worker had in the past (knowledge of the territory, atmospheric phenomena, tides, hydrodynamics, geographical socio-polítical context), is now dying away.

Durrésí- VIora Region The Durrési-Vlora coastal region, is generally characterized by coastallowlands

(alluvial plains) intersected by rivers, and

flanked by hills along its upland boundary. The coast is made up of long saridy beaches, deltaic river mouths and lagoons. Four large rivers drain into the region, starting with Ishmi and Erzeni in the north, followed by the Shkumbini, Semani and Vjosa towards south. The drainage basins of these rivers have led to the formation of diverse and productive wetland complexes at the interface of the Adriatic Sea and the landward flood plains. These wetlands include coastallakes and lagoons, including the two biggest Albanian lagoons: Karavasta and Narta (where salt pans can be found), maritime forests, barrier dune and insular systems, and mountains that support rich and globally significant diversity of habitats and species. Administratively, the area has been subdivided into five coastal districts: Durrési, Kavaja, Lushnja, Fieri and Vlora. Only the southem part of the Vlora district, which by its geographic features belongs to the Ionian coastal area, is not included in the project. The Durrési- Vlora region (including the southem part ofthe Vlora district) covers an area of 4,344 sq kilometers, or about 15% of the national territory, and has the population of 820,699 which is more than 25% of the country's total (1990). Excluding the lagoons, its 207 kilometers of the coastline make up 48.3 % of the totallength of Albania's coast.

The most dynamic area of the region will continue to be the coastal transportation axis which links all the important settlements in the region and attracts population not only from the region's highlands but also from other mountainous parts ofthe country. Of course, the concentration of coast-dependent activities such as sea transportation, fisheries, tourism and services are the additional factors which will stimulate the development and growth of the cities of DurrĂŠsi and Vlora. Furthermore, with the construction of tourist establishments and adequate infrastructure on attractive but presently isolated parts of the coast, it is realistic to expect that some settlements of strictly rural character will develop too. intemationally important wetland: the quality and peculiarity of flora and fauna which add a genetic and ecological diver-

It is important to link tourism with nature conservation through the establishment, not only of environmental standard s for facilities but also ensuring that large areas of nature are protected. Protected areas (proposed on the basis of IUCN classification), are focal points that can attract people and therefore funds to both local communities and national treasuries. Before designating protected areas, it is important to consider the concept of carrying capacity. This is usually defined as the level of visitors' use a site can withstand and still retain a high level of visitors' satisfaction.

What is needed to meet this objective is to incorporate the principies of ICAM in "sectoral" laws which refer to the country as a whole (e.g., Forestry Law), but also to develop and adopt specific regulations and by-laws which will refer to the coastal zone alone, or to different parts of the coastal systems (land and sea) and their different activity sectors (fishing, agriculture, tourism, oil and gas exploitation, nature conservation, etc.).

This is a positive process because the shore is again free and not influenced by feeding. Also, the conditions of farming in deeper sea are much better. More streams, more oxygen, less possibilities of different fish diseases, etc. inspires the farms having more than 50 ton year production, to think about their moving towards the open sea.

The vegetal component In spite of the irreversible alteration from the original conditions, nowadays the vegetation of San Giovanni-Mogoro river wetland system is distinguished and influenced by the ecological factor water. In fact, in conformity with the salt concentration gradient, which increase toward the Mogoro river mouth, different plant communities has been inventoried, exc1usively riparian plants along the Mogoro river and halophytes dominating the San Giovanni habitat. The vegetal component is also influenced by the water flow regime, which permit the distinction within the biotope of two environments: lentic and lotic ecosystems. All that contribute to the habitat variability verified on the basis of the vegetation and fauna biodiverity. From riparian hygrophyle woods ofPopulusalba andPopulus canescens interposed with little grouping of Fraxinus oxycarpa, Ulmus minor, Salix spp and rare individuals o/ Quercus pubescens, there is a progressive transition to secondary degradation of the vegetal covering near the river mouth.

Several wetland habitats, such as salt marshes, salt pans and salt works, are known as very important places for biodiversity conservation, for instance for their importance on breeding, migration and wintering of several bird taxa. What is far less known is how do other vertebrate taxa (i. e. Chiroptera) use these habitats, in comparison with other habitat types. During the last ten years, the

It is evident from the data listed in Table 1 that in the wetland habitats the composition in species may change, accordingly to the bat fauna of the region and to the landscape characteristics. Anyway, this is the only habitat type were we found species known to feed mainly on moths (the two Horseshoe bats and P austriacus), or beetles and grasshoppers (respectively M myotis andM blythi, the two largestMyotis species). Eptesicus serotinus and Tadarida teniotis are high level flying species of considerable size, so that they may be found here because they are attracted by insect density and/or insect diversity high over the ground. Salt works, salt ponds and coastal lakes probably show an entomofauna composed mainly small and soft insects, such as Diptera, that my support only Pipistrellus and small Myotis bats such as M capaccinii. From these data, it is apparent that well vegetated wetlands represent the key-stone areas for bat conservation purposes in coastal environments.

were the first to discover the natural attractions of the islands, leading to an invasion of their coasts. One of the reasons that has enabled these mainland tourists to be the first to arrive is the fact that they are not dependent on transport time tables.(transport is provided by the national shipping line and represents one of the nerve centres of island development). As you can see, the current situation in the Zadar and Sibenik Islands is a highly contradictory one. The ecological quality of the environment owes nothing to sensible policies based on the principle of sustainable use of natural resources. This environ-

century have had a direct and negative impact on population. The decrease in the population, on the other hand, has had a direct and positive effect on the ecological state of the sea bed and the coastal waters. One can see that the protection of the islands and the ecological balance have developed spontaneously. The lack of a working population has curbed industrialisation. Hotels are very scarce. The only factory in the islands, the canning factory in Sali, on the island of Dugi Otok, and the only ship yard, in Ugljan, only survive because they are necessary, and they have to bring some of their employees across from the mainland. The demographic situation has pre-empted the presence of practically all potential pollutants throughout the towns of the islands.

Savar, Sipnate, Piskera, Lavsa, Hramina, etc. Nowadays, most of these sites are below the surface, because the eastern coast of the Adriatic is sinking at the rate of one millimetre per year, due to geological reasons. Since the introduction of lights in fishing in the 16th century (introduced by Cedollini, an aristocrat from Zadar, in 1512), the Kornati Islands have become the most important fishing grounds of the Adriatic. This is illustrated by the fact that, at one time, the village of Sali (Dugi Otok) had 64 boats equipped for fishing sardine and mackerel. All this information clearly shows that there is a deep-rooted tradition of fishing, fish rearing and canning among the people the effects of the political changes in the country have not yet been felt, everybody is fully aware that it can not be long before

At the same time, they spread a new wave of collaboration throughout the Bay's municipalities.

NEW PERSPECTJIVES AT THE THRESHOLD OF THE XXI CENTURY

1997

CONCLUSIONS On 19-20 April 1997 several experts, organisations and agents responsible of mediterranean coastal artificial wetlands met in Paris, at the UNESCO headquarters. The conclusions of the working sessions sum up the main challenges and measures to be adopted to preserve and improve this common heritage.

1. For the last thousand years, salt working, traditional aquaculture, and some coastal ricefields have given rise to

the development of activities, due to the superimposition

of competition. • the lack of information and social evaluation of the areas

and associated activities. • technological difficulties in the search for new replacement

spaces reveals a very serious problem, which has taken the form of the threatened disappearance or radical transfor-

activities, compatible with conservation. 5. For several years now, there has been a growing awareness of these problems, which has had a profound effect on pro-

mation of more than 100.000 ha of this type of valuable ecosystem created by man, which represents the most im-

ducers and local administrations, researchers and Non-Governmental Organisations. This is based on the rediscovery

to the decline of more extensive neighbouring wetlands.

6. According to the aforementioned reasons, we believe that a rehabilitation of these systems would be fair since:

Summary of proposals and recommendations To influence the professional training of young people in order to recover traditional occupations and the development of compatible new activities. It is necessary to work in close collaboration with agricultural bodies (agricultural chambers), local collectives, and professional organisations (trade unions and co-operatives). . To favour framework agreements between the different sectors and producer companies, on a national and regional scale, by encouraging joint campaigns for the image and recovery of lost or potential market niches. To demand that the competent administrations provide precise regulations concerning the use of denominations and a greater control over truthful consumer information.

To favour the introduction of eco-touristic activities as a reevaluation factor and the contribution of complementary economies. The sustainable management of tourism may

ingly valuable and beautiful semi-natural and cultural habitats. Many ofthese are meticulously cared for gardens of the past and areas that now fight for survival amid coastal factories, motorways and housing estates. The surviving salinas bear the scars of the historic battle they have fought this century; surviving miraculously among the drab, uniform landscape that characterises many of man's interventions along the coast in recent years. A deep-rooted awareness that they form part of the common heritage, the work of long-suffering salt workers who have conserved traditional production methods come hell or high water and campaigns by social groups have managed to preserve a large proportion of this legacy. In many areas, conservation has advanced from the point where the need was recognised into the practical stage. Information centres, museums and guided tours have been developed in several active and abandoned salinas, gradually forming one of the most attractive eco-tourism and cultural products of the coasts of Europe.

Traditional salt production could also benefit from the idea of a common Salt Route; something that would enhance the value of an ecological product, as the Guerande experience has shown.

XI of the European Commission, INSULA has started to promote the initiative by creating an Internet Web site for the Salt Route that, from the beginning, has included the main centres and sites to visit in the Mediterranean. It should be mentioned that the logo used to launch the project was designed by the late Cesar Manrique, an artist from the island of Lanzarote and one of the first people to propose the idea of conserving the salinas as a common heritage of man and nature, more than ten years

FRANCE One of the most important active salinas of Europe, with an average yearly production of 1,200,000 metric tonnes (1992) is to be found on the French Mediterranean coast. There are several, historically important salinas in the area. Salt pans of the Bas Languedoc coastal lagoons These include the salinas of Leucate, Agde, Sete and Maugio. The examples mentioned include a wide variety of functions and types of salinas: the Agde saltworks are maintained as an artificial bastion of salt production, after the Thau lagoon silted up; the Ayrolle salinas, located behind the line of sand dunes that form the lagoon.

techniques of the Mediterranean. Among the most interesting salinas is the primitive Cythera salt pans, the only ones of their kind that remain in Greece, and practically the only ones of their kind in the whole Mediterranean area of the European Union. One can also see a faithful reproduction of the Mediterranean salina layout in the ancient plans of the Milos salt pans. Another aspect that highlights the importance of the traditional Greek salinas is the fact that ten major groups of traditional salt workings are out on the islands, and these present an enormous variety of solutions for the salt industry. In contrast to the decadence of other European regions, in recent years, large saltworks, such as Messi, N. Kessani and M. Evolo, have been mechanised. Other interesting salinas are the

SALINAS OF THE EASTERN MEDITERRANEAN The salinas of Cyprus have also been famous since the times ofPliny, who claimed that the best salt was the salt produced in Salanis. In the 16th century, Cyprus reached an average level of production of 10,000 tonnes a year. Ever since ancient times, many successful attempts at salt production have been seen along the northern coast of the Black Sea, rich in salt lakes and lagoons. The Greeks used to bring their provisions of salted fish from these shores. In the 19th century, despite the low salinity levels ofthe Black Sea, the Crimea reached production figures of 200,000 tonnes a year. The south coast of the Black Sea, however, has never been suitable for salt production. The Turkish coast has never produced great quantities of salt either, although it has had famous salinas, such as Phokaia, Tragassaean and Priini. This, more than anything, is due to the inhospitable nature of the coastline, which does not permit ships

THE HERITAGE OF THE MEDITERRANEAN SALINAS CULTURE? NATURE AND LANDSCAPE

The traditional Mediterranean salinas, along with some of the extensive sea-harvesting grounds and coastal rice fields, form a heritage that is not just of tremendous ecological, cultural and architectural interest, they also represent one of the most impressive man-made landscapes imaginable. Anyone who has visited a working salinas will have felt the power of the landscape. Incapable of explaining the harmony of man's ingenuity, we resort to expressions like beauty or art to describe the delicate balance between the elaborate architecture of the water and the way it blends so exquisitely with the environment.

To rationalise such perceptions, one must consider the world of the salt pans from the standpoint of many different-disciplines and trades that are either directly related to, or implicitly involved in, this world. Salinas, like some other man-made spaces such as rice fields and extensive sea-harvesting systems, are interesting because of their ideal strategic location, which optimises the

The similarities to farming activities are evident in the form of construction, the implements used, the system of irrigation and because yield depends on man's labour and the annual cycle of the sun. The system of production is reminiscent of the order of the plantations in their tidiness and straight lines, and the care taken and the cleanliness employed in the work make it similar to the most classical tradition of gardening.

The only technical advances that have been incorporated in the course of the last two thousand years have been in the implements used, and in water elevating and propulsion devices. Salinas can be divided by production processes, size of the ponds and the harvesting system into the following categories: Intensive Semi-intensive Extensive In the latter group, one must distinguish between traditional and modern continuous crystallisation methods.

The same principle of unity of resources, which becomes unity of design, is also the basic inspiration for the rest of salt pan architecture. The salt warehouse, houses, the bases of windmills, are all made out of the same stone that is used to build the salt pans, forming an harmonious whole that blends into the landscape.

Magnificent examples of these buildings can still be found in Piran, the Bay of Cadiz or in Marsala. One important point concerning the materials used, is the "uniformity" of construction materials that one observes in the typical sections of the different elements of anyone kind of salt pan.

Artificial wetlands as Cultural Landscapes All the above-mentioned factors together make these areas very special ones. Salinas have an exceptional value added as well, as they generally form one of the most singular and suggestive landscapes of the whole Mediterranean coastline. The value of these environments is currently on the increase and many conservation initiatives have been taken for this very reason. After all, the salinas constitute one of the most harmonious expressions of man's intervention on the coastline. They represent a fine example of how man has used an exhaustive reconnoitring of the terrain and its potential as the basis for harnessing its resources. Moreover, as we have had the chance to see, many of the Mediterranean salt pans shelter an historic and ethnological heritage that still remains to be evaluated.

Other groups of birds, like ducks and grebes, use their swimming and diving abilities to find food at greater depths. Some, like the Common Gallinule (Gallinula chloropus), are perfectly adapted to life among the aquatic plants of the edges. The waders are also well adapted to the habitat and can make the most of the food resources to be found in the silt and mud of the shallow pools. Finally, some typically predatory birds, such as the osprey, have specialised in catching fish in these shallow water habitats. It is important to highlight the fact that, from an ornithological point of view, the quality of the salt pan habitats is determined by the water level - which varies enormously from one
