    Biological quality of lakes

    This indicator represents the Cyanobacteria percentage of total phytoplankton biomass. This is an indicator of eutrophication.

    Emissions of organic matter

    The emission of organic matter is a key environmental problem. Among the pollutants mentioned are Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Organic Carbon (TOC). BOD, COD and TOC are key indicators of the oxygen content of water.

    Freshwater quality

    This indicator shows:

    1. Annual median concentrations in rivers of Biological Oxygen Demand (BOD) and ammonium (NH4).

    2. Trends in concentrations of orthophosphate and nitrate in rivers, total phosphorus and nitrate in lakes, and nitrate in groundwater bodies.

    Units

    The concentration of nitrate is expressed as mg nitrate (NO3)/l for groundwater and mg nitrate-nitrogen (mg NO3-N/l) for rivers and orthophosphate and total phosphorus as mg P/l.

    Habitats of European interest

    The indicator shows changes in the conservation status of habitats of European interest.
    It is based on data collected under the reporting obligations of Article 17 of the EU Habitats Directive (92/43/EEC).

    Nationally designated areas

    Areas designated under national legislation for the purpose of nature protection including sites such as national parks and nature reserves.

    Soil erosion by water

    EU-wide estimates of erosion are based on modelling studies. Most models contain a rainfall erosivity factor and a soil erodibility factor that reflect average precipitation conditions. Typical values for these factors may inadequately represent the impact of extreme rainfall. Therefore, the uncertainty of modelled erosion risk is high, especially at local level.

    Species interactions

    Projected spatial mismatches of the Portuguese Dappled White butterfly and its host plants

    Water productivity (GDP/Water Footprint)

    "The indicator illustrates the amount of economic value generated by unit of water consumption. It is calculated as GDP (in Purchasing Power Standards /PPS) divided by the Water Footprint (WF) of a country."

    Water scarcity index

    Water scarcity is the lack of sufficient available water resources to meet the demands of water usage within a region.

    Physical Trade Balance (PTB)

    The trade surplus or deficit of material resources within an economy, calculated as imports minus exports of raw materials and manufactured products.

    Total wealth estimate ($)

    "The Wealth of Nations dataset provides country level data on comprehensive wealth, adjusted net saving, and non-renewable resource rents indicators, as published in "The Changing Wealth of Nations" (2011)."
    (World Bank, http://data.worldbank.org/data-catalog/wealth-of-nations, 23-01-2015)

    "Total wealth is present value of future consumption that is sustainable, discounted at a rate of time preference of 1.5 percent, over 25 years.

    Depletion Adjusted Saving (DAS) =

    Adjusted net savings, including particulate emission damage (current US$)

    Adjusted net savings are equal to net national savings plus education expenditure and minus energy depletion, mineral depletion, net forest depletion, and carbon dioxide and particulate emissions damage.

    Environmental Vulnerability Index

    The Environmental Vulnerability Index is a measure to characterize the relative severity of various types of environmental issues suffered by individual nations and some regions of the planet.

    Adjusted savings: natural resources depletion (% of GNI)

    Natural resource depletion is the sum of net forest depletion, energy depletion, and mineral depletion.

    Proportion of annual renewable freshwater resources stored in reservoirs in European countries

    The indicator shows the proportion of annual renewable freshwater resources stored in reservoirs in European countries
