By 2020, pollution, including from excess nutrients, has been brought to levels that are not detrimental to ecosystem function and biodiversity.

System of Environmental-Economic Accounting

The System of Environmental-Economic Accounting (SEEA) provides a framework for measuring the links between the environment and economy.

The SEEA consists of two parts. The SEEA Central Framework (SEEA CF) was adopted by the UN Statistical Commission as the first international standard for environmental-economic accounting in 2012. The Central Framework looks at individual environmental assets, such as water, forests and fisheries resources, and how they are extracted from the environment, used within the economy, and returned to the environment as air, water, and waste.

A linked land-sea modeling framework to inform ridge-to-reef management in high oceanic islands

This linked land-sea modeling framework helps assess the relative influence of terrestrial and marine drivers on coral reef communities. It links land cover/use to coral reefs through analyzing nutrient-enriched groundwater flux. Based on climate, groundwater recharge and recharge nutrient concentration data, groundwater flow and nutrient flux discharging at the coast are modeled. The model was developed for two ahupua’a, or traditional ridge-to-reef management systems, in Hawaii.
