UN Sustainable Development Goals - SDG 14

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, to achieve healthy and productive oceans.

14.5 By 2020, conserve at least 10 per cent of coastal and marine areas, consistent with national and international law and based on best available scientific information.

GEO ECOSYSTEMS Initiative: Global Ecosystem Mapping

Develop a standardized, robust, and practical global ecosystems classification and map for the planet’s terrestrial, freshwater, and marine ecosystems.

The ECU Mapping Approach – Environmental Stratification

We will quantitatively segment (stratify) the global coastal zone into environmentally distinct/ecologically meaningful units.
