    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.

    Species interactions

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

    Fresh Water Resources

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

    Living planet index

    Environmental Performance Index

    Environmental Performance Index is an indicator that measures environmental performance compared to two main objectives: Environmental Health and Ecosystem Vitality. Environmental Health measures the protection of human health from environmental harm. Ecosystem Vitality measures ecosystem protection and resource management. These two objectives are further divided into nine issue categories that span high-priority environmental policy issues, including air quality, forests, fisheries, and climate and energy, among others.

    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.
