SUSTAINABLE DEVELOPMENT GOAL 14
Conserve and sustainably use the oceans, seas and marine resources for sustainable development

Progress of goal 14

  • Oceans, along with coastal and marine resources, play an essential role in human well-being and social and economic development worldwide. They are particularly crucial for people living in coastal communities, who represented 37 per cent of the global population in 2010. Oceans provide livelihoods and tourism benefits, as well as subsistence and income. They also help regulate the global ecosystem by absorbing heat and carbon dioxide from the atmosphere and protecting coastal areas from flooding and erosion. In fact, coastal and marine resources contribute an estimated $28 trillion to the global economy each year through ecosystem services. However, those resources are extremely vulnerable to environmental degradation, overfishing, climate change and pollution. The sustainable use and preservation of marine and coastal ecosystems and their biological diversity is essential to achieving the 2030 Agenda, in particular for small island developing States.
  • Pollution of both land and seas is a threat in many coastal regions. In addition, since river basins, marine ecosystems and the atmosphere are all part of hydrological systems, the effects of such pollution are often felt far from their source. In many coastal communities, pollution and eutrophication, which is the presence of excessive nutrients in water, frequently owing to runoff from the land, causing dense plant growth and the death of animal life, are driving detrimental changes. The five large marine ecosystems most at risk from coastal eutrophication, according to a global comparative assessment undertaken in 2016 as part of the Transboundary Water Assessment Programme, are the Bay of Bengal, the East China Sea, the Gulf of Mexico, the North Brazil Shelf and the South China Sea.
  • Since the beginning of the industrial revolution, the ocean has absorbed about one third of the carbon dioxide released by human activities, thereby mitigating the full impact of climate change. However, this comes at a steep ecological price, as dissolved carbon dioxide in seawater lowers the pH level of oceans, thereby increasing acidity and changing the biogeochemical carbonate balance. Concerns about ocean acidification, first expressed in the early 1980s, have now been confirmed, and the extent of its impact on marine ecosystems is being investigated.
  • Fisheries contribute significantly to global food security, livelihoods and the economy. However, if not sustainably managed, fishing can damage fish habitats. Ultimately, overfishing impairs the functioning of ecosystems and reduces biodiversity, with negative repercussions for sustainable social and economic development. In order to achieve a healthy balance, fish stocks must be maintained within biologically sustainable limits, at or above the abundance level that can produce maximum sustainable yields. Based on an analysis of assessed stocks, the percentage of world marine fish stocks within biologically sustainable levels declined from 90 per cent in 1974 to 69 per cent in 2013. Fortunately, the downward trend has slowed and appears to have stabilized since 2008.
  • Biodiverse marine sites require safeguarding to ensure sustainable long-term use of their precious natural resources. Globally, in 2014, 8.4 per cent of the marine environment under national jurisdiction (up to 200 nautical miles from shore) and 0.25 per cent of the marine environment beyond national jurisdiction were under protection. From 2000 to 2016, the share of marine sites around the world that are designated as key biodiversity areas and are completely covered by protected areas increased from 15 per cent to 19 per cent.

EU SDG indicator set

To measure SDG achievement in an EU context, an EU SDG indicator set was developed under the leadership of eurostat. the purpose of this set, which is structured along the 17 global sdgs--sustainable development goals, is to monitor progress towards the sdgs at the european level. it is based on existing european sustainable development indicators like those of the europe 2020 strategy, the previous eu sustainable development strategy and the 10 commission priorities.
