Ecological footprint - Water footprint Ecological footprint Water footprint footprint components use of natural capital as a source use of natural capital as a sink • arable land • pasture land • forest/woodland • built-up land • productive sea space • land for CO 2 absorption • green water (green WF) • blue water (blue WF) • water to assimilate pollution (grey WF) adding different footprint components actual areas are weighted by equivalence factors before adding actual water volumes are added without weighting
Ecological footprint - Water footprint local versus global productivity ceiling to sustained natural resource appropriation ecological reservation Ecological footprint most EF analyses are based on global average productivities (kg/ha/yr) sum of biologically productive areas (biocapacity) (in ha) biodiversity land Water footprint WF analyses are generally based on actual virtual-water content of products (m 3 /kg) available freshwater resources (in m 3 /yr) environmental flow requirements
