Goal 14

14.1.1(a) Index of coastal eutrophication; and (b) plastic debris density
Coastal areas are areas of high productivity where inputs from land, sea, air and people converge. With over 40 per cent of the human population residing in coastal areas, ecosystem degradation in these areas can have disproportionate effects on society (IGOS, 2006). One of the largest pressures on coastal environments is eutrophication, resulting primarily from land-based nutrient input from agricultural runoff and domestic wastewater discharge. Coastal eutrophication can lead to serious damage to marine ecosystems, vital sea habitats, and can cause the spread of harmful algal blooms. Across indicators 4.1.1 (a) Index of coastal eutrophication and 14.1.1 (b) Floating plastic debris density, two levels of data collection are proposed:
- Level 1: Globally available data from earth observations and modelling
- Level 2: National data which will be collected from countries (through the relevant Regional Seas Programme, where applicable (i.e. for countries that are a member of a Regional Seas Programme)
