Establishing integrated nitrogen management systems for the Gulf of Riga
by Ministry of the Environment (Estonia) (Government)
Human induced nitrogen loads to the environment and marine environment are exceeding planetary boundaries. Existing measures focusing sectoral nitrogen pollution sources have not provided sufficient solutions to tackle the problem. The objective is to use new approach to manage the nitrogen flows by taking into account also different reactive forms of nitrogen present in the nitrogen cycle. This provides a better and cross sectoral view on nitrogen flows and improved opportunities to target the specific and most relevant nitrogen pollution sources. As a result of this action the integrated nitrogen management system will be stablished to improve the status of the Gulf of Riga.
Progress reports
By 2025, prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollution
Type of commitment
  • Fertilizer use efficiency
  • Wastewater treatment
  • Manure management
  • Nutrient sinks (e.g. constructed wetlands)
