Title: Questions to be answered by a state-of-the-environment report |
---|
Title (other): The first list |
Abstract This document is the final report of a study undertaken by the EEA together with its Expert Group on Guidelines and the State of the Environment Reporting in 1999-2000. It lists questions of policy makers and the general public that could be used to set up a state of the environment report or an environmental indicator report. It should be seen as a 'living' document that can be amended in the future through new versions, and certainly not as a definitive and universal one.[Author vide copyright] |

Title (other): Submission to the Executive Body of the UNECE Convention on Long-range Transboundary Air Pollution |
Abstract This study has collated available environmental expenditure data on the market for goods and services produced by eco-industries in both the EU-15 and the Candidate Countries, as the basis for describing the economic significance of the sector, including employment levels. Whilst there are gaps and inconsistencies in the available data sets, only limited estimation procedures are required to derive a detailed and rigorous basis for economic analysis. The study also provides insights into the export capabilities of EU Member States, particularly their relationship with the Candidate Countries. For the purposes of this study, eco-industries have been defined according to the definition contained in 'The Environmental Goods and Services Industry - Manual for Data Collection and Analysis' (OECD/Eurostat, 1999). This defines eco-industries as 'activities which produce goods and services to measure, prevent, limit, minimise or correct environmental damage to water, air and soil, as well as problems related to waste, noise and eco-systems. This includes cleaner technologies, products and services that reduce environmental risk and minimise pollution and resource use'.[Author vide copyright] |

Title: The Arctic biogeographical region |
---|
Title (other): warming up and changing? |
Abstract # The Arctic biogeographical region has a highly varied landscape and contains some of Europe?s few remaining large wilderness areas.# The climatic conditions put extreme pressure on plants and animals, and large parts of the region are still under glaciation. Permafrost is widespread.# There are few winter-active species, but very large populations of summer-active plants and animals.# Large numbers of many migrating birds and fish species link arctic ecosystems inextricably with the conditions of circumpolar ecosystems as well as with Europe, northern Asia and Africa.# Large parts of the region are dominated by coastal habitats and interchange with the sea is a dominant feature.# Predicted increases in temperature of some degrees may change conditions radically in many areas and shift plant and animal communities towards more boreal types. Distributions of existing species and habitat types would shift northwards to higher latitudes and upwards to higher altitudes. Some species may become extinct.# There are significant anthropogenic impacts from long-range air pollution, and in some areas from long-term overgrazing and recently from tourism.[Author vide copyright] |

Title: The Baltic Sea |
---|
Title (other): the largest brackish sea in the world |
Abstract The Baltic is the largest brackish water system in the world. Its only connection to more open seas are the shallow sounds between Sweden and Denmark. x01x02 The sea is slowly shrinking because of geological uplifting of land after the last glaciation. x01x02 In many respects the Baltic is similar to an inland lake or an estuary. It is unique in that there are areas where freshwater, brackish water and marine species are all present. Its salinity increases from east to west and from north to south. x01x02 The marked vertical and horizontal salinity gradients are reflected in different species communities and species numbers. The highest biodiversity is found in the south-west of the Baltic Sea. x01x02 Many of the marine species are at the limit of their distributions. x01x02 The main threats to biodiversity in the Baltic Sea are: o Eutrophication: this has caused increased amounts of planktonic algae, increased frequencies of toxic blooms of algae, the reduction of oxygen levels in the deep waters of the Baltic and a decline or disappearance of larger perennial macroalgae. o Fisheries: Fishery of the main target fish species such as cod, herring, salmon and eel is presently unsustainable due to over-exploitation and impairment of conditions for reproduction. Bycatches of marine mammals, seabirds and non-target fish species are too high. o Pollution by contaminants and oil: Organic contaminants have caused health and reproduction problems in marine mammals and birds. Oil has killed seabirds and negatively effected benthic communities. o Introduction of non-indigenous species: Changes in the structure and components of the ecosystem are caused by introduced species. Intentional introduction, fouling and ballast water are three important ways organisms have been introduced into the Baltic Sea. The river connections with the brackish waters in the Black and Caspian Seas increase the risk of introduction from these areas.[Mats Walday ; Tone Kroglund] |

Title: The Black Sea |
---|
Title (other): an oxygen-poor sea |
Abstract Nearly 87 % of the Black Sea is entirely anoxic (without oxygen) and contains high levels of hydrogen sulphide. This is the result of past geological events, its shape and its specific water balance (high degree of isolation from the world ocean, deep water depression with a maximum depth of 2 212 metres (m) in the centre of the sea, the extensive drainage basin and the large number of incoming rivers). x01x02 Deep pelagic and benthic organisms are largely absent. x01x02 The wide diversity of biotopes provides favourable conditions for invasion of alien species to the Black Sea. x01x02 The composition and structure of the marine communities is constantly changing with the decline of certain species and the expansion of others. x01x02 Generally, in undisturbed natural conditions species diversity in Black Sea fauna is approximately three times less than that in the Mediterranean. x01x02 Increasing salinity due to inappropriate water management and regulation, and pollution of brackish coastal lakes and estuaries represents a threat to relics and endemic species, especially in the Sea of Azov. x01x02 As a result of eutrophication, primary production has increased and the number of species has declined. These changes, as well as inappropriate fishing practices, have affected the fish stocks. A change towards small pelagic fish, i.e. anchovy and sprat, has been observed. x01x02 Deterioration of some marine habitats and a lack of laws and technology for regulating the introduction of alien species, for example via ballast waters, have allowed the invasion of such species. These have produced mass populations, which have changed the equilibrium of the native marine ecosystems. Growing concern for the fate of the Azov-Black Sea basin is stimulating a search for efficient countermeasures to combat unwanted alien settlers, since they are now the dominant species across the food web. x01x02 Overexploitation of fish stocks in combination with the invasion of the comb jellyfish Mnemiopsis leidyi has caused the collapse of |

Title: The Arctic Ocean |
---|
Title (other): home of the walrus |
Abstract The Arctic Ocean covers a large area with harsh climatic conditions. x01x02 There are strong seasonal and geographical variations in light, temperature and ice cover. x01x02 The European part of the Arctic Ocean covers only about 8 % of the total area of the Arctic Ocean, but due to its great depth it represents about 25 % of the total volume. x01x02 The system of ocean currents induces an east-west temperature gradient with warmer conditions in the eastern part of the European Arctic Ocean, strongly influenced by the warm Gulf Stream. This keeps the Norwegian Sea and a large part of the Barents Sea ice-free and favourable for the growth of a wide range of open-sea (pelagic) and bottom-living (benthic) species. This biological production sustains huge stocks of pelagic fish in these areas. x01x02 The extreme conditions in the area create unique marine ecosystems, and some species live on the border of their tolerance. x01x02 Generally, the environmental quality of these waters is high, but there are several reasons for concern, and an urgent need for more knowledge about the biological systems in this vulnerable area. x01x02 The main threats to biological diversity in the Arctic are o Extensive fishery is probably the greatest threat to biodiversity today. A better understanding of the effects of these fisheries is needed, especially of the effects of bycatch and effects on benthic habitats. o Effects of climatic changes are not yet unequivocally identified, but global warming can influence hydrographical conditions in the region. The recent possibility of ship passage along the Siberian coast may be an indication of such effects. o Accumulation of micro-contaminants in biota is of great concern, particularly since little is known about the relation between levels of contaminants and biological effects. Discharges from industry in the Russian area of Murmansk are considerable and make up a substantial part of total industrial outputs to the Arctic. Long-distance transport of contaminants from other areas is |
