    Ecological Footprint

    The Ecological Footprint represents the productive area required to provide the renewable resources humanity is using, as well the area required to absorb the waste emitted.

    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.

    Nationally designated areas

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

    Soil organic carbon

    Soil organic carbon is the carbon (C) stored in soil organic matter (SOM). Organic carbon (OC) enters the soil through the decomposition of plant and animal residues, root exudates, living and dead microorganisms, and soil biota. SOM is the organic fraction of soil exclusive of nondecomposed plant and animal residues. Nevertheless, most analytical methods do not distinguish between decomposed and non-decomposed residues. SOM is a heterogeneous, dynamic substance that varies in particle size, C content, decomposition rate, and turnover time.

    Species diversity

    Species diversity is a measure of the diversity within an ecological community that incorporates both species richness (the number of species in a community) and the evenness of species' abundances. Species diversity is one component of the concept of biodiversity.

    Conservation status of habitats by habitat group

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

    Fresh Water Resources

    Internal flow and actual external inflow of surface and groundwater in millions of cubic metres per thousands inhabitants.

    Living planet index

    The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.

    Environmental Sustainability Index

    The Environmental Sustainability Index (ESI) is a measure of overall progress towards environmental sustainability, developed for 146 countries. The index provides a composite profile of national environmental stewardship based on a compilation of 21 indicators derived from 76 underlying data sets.
