SDG #14 is to “Conserve and sustainably use the oceans, seas and marine resources for sustainable development.”
Within SDG #14 are 10 targets, of which we here focus on Target 14.2:
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
Target 14.2 has one indicator:
Indicator 14.2.1: Number of countries using ecosystem-based approaches to managing marine areas
The progress for this indicator to measure countries with plans to manage the environment of their coastal zones is sparing as of 2021. The countries with such ecosystem-based coastal management include:
Colombia
Jamaica
Germany
Denmark
Bulgaria
Finland
China
South Korea
All the Southeast Asian countries, except Myanmar and landlocked Laos
All other countries either haven’t supplied data for this indicator, or don’t have such an ecosystem-based coastal management.
