from plastics Target 14.2: Protect and restore ecosystems The full title of Target 14.2 is: "By 2020, sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts, including by strengthening their resilience, and take action for their restoration in order to achieve healthy and productive oceans". This target has one indicator: Indicator 14.2.1 is "Number of countries using ecosystem-based approaches to managing marine areas". This indicator aims at protecting and managing sustainably the marine and coastal ecosystems to avoid adverse impacts. An exclusive economic zone (EEZ) is a sea zone prescribed by the 1982 United Nations Convention on the Law of the Sea over which a sovereign state has special rights regarding the exploration and use of marine resources, including energy production from water and wind. No data is available for this indicator yet. Target 14.3: Reduce ocean acidification The full title of Target 14.3 is: "Minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels". This target has one indicator: Indicator 14.3.1 is the "Average marine acidity (pH) measured at agreed suite of representative sampling stations". No data is available for this indicator yet. Ocean acidification is directly addressed by the target SDG 14.3. Ocean acidification is impacting on the ecosystems of marine environments that provide food, livelihoods, and other ecosystem services for a large proportion of the human population. Some 1 billion people are wholly or partially dependent on the ecosystem services provided by coral reefs in terms of fishing, tourism, and coastal management. SDG 14 is fully intertwined with the impacts of ocean acidification, as its focus includes the protection and restoration of ecosystems, sustainable fishing, protection of coastal and marine areas and protecting the economic benefits derived from marine resources. Target 14.4: Sustainable fishing The full title of Target 14.4 is: "By 2020, effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices and implement science-based management plans, in order to restore fish stocks in the shortest time feasible, at least to levels that can produce maximum sustainable yield as determined by their biological characteristics". This target has one indicator: Indicator 14.4.1 is "the proportion of fish stocks within biologically sustainable levels". This indicator aims to measure the proportion of global fish stocks which are overexploited, fully exploited and not fully exploited. A levels of fish stocks is sustainable if it is
