GURINIMAS is an Estonia-Latvia Interreg project (Integrated Nitrogen Management System for the Gulf of Riga). The project contributes to the implementation of the EUBSRS priority area “NUTRI - Reducing nutrient inputs to the sea to acceptable levels” and the achievement of the EUBSRS objective “Save the Sea”.
Background of the project
The water quality of the Gulf of Riga is impacted by economic activities both in Estonia as well as in Latvia. The good status for the gulf, incl. coastal waters is not yet achieved because of the excessive nutrients in the water body. Nitrogen provides lots of benefits as for food production and industrial products, e.g. fertilisers. It is also the unwanted side product in case of the nitrogen emissions to the air or discharges to the water.
Excessive nitrogen loads coming from many land-based sources, within and outside the catchment area of the Baltic Sea Region states, is one of the main causes of the eutrophication of the Baltic Sea. Excess nitrogen have effects not only to water systems, but also to terrestrial systems and atmosphere also expressed e.g. by ozone induced injury to crops, acidification and eutrophication effects on forest, soils and freshwater aquatic systems, leaching, eutrophication and hypoxia in coastal and lake ecosystems, etc.
Measures to cut the nitrogen load have been traditionally targeted to agricultural, industrial and energy sectors and urban areas that are the main sources of nitrogen in the Baltic Sea catchment area. Currently it has been acknowledged the need to address in an integrated way the whole range of N sources and pathways which can have significant eutrophication impacts such as forestry, aquaculture, fur farming, transport, including shipping etc. The movement of nitrogen from one system to another can be described as a cascade where part of the N accumulates or lost through denitrification within a system and the rest transfers to the next system with a certain time lag.
GURINIMAS on Eesti-Läti Interreg programmist rahastatav projekt "Liivi lahe lämmastiku haldamise integreeritud süsteem", mis kestab 01.04.2017 kuni 30.09.2019. Projekti eesmärgiks on lämmastiku koormuse vähendamine Liivi lahele koostöös Eesti ja Läti ameti- ja teadusasutustega. Lämmastiku haldamise integreeritud süsteem hõlmab lämmastikutsükli põhjalikku analüüsi ja Liivi lahe piirkonna riskipiirkondade määratlemist, kus võtta vajalikke meetmeid. Projektis arendatav uus integreeritud lämmastiku juhtimissüsteem annab osalevatele riikidele - Eestile ja Lätile - ühtlustatud raamistiku, mida hiljem rakendavad Eesti ja Läti ametiasutused.
Projekti juhtpartneriks on Eesti Keskkonnaministeerium, lisaks osalevad Tallinna Tehnikaülikool, Läti Keskkonna Geoloogia- ja Meteoroloogiakeskus, Läti Riiklik Metsanduse Instituut "Silava", Läti Hüdroloogia Instituut ja Läti Põllumajandusülikool.
The objective of the project
The objective of the project is to develop an integrated nitrogen management system for the Gulf of Riga in close cooperation between Estonian and Latvian authorities and research institutions. The integrated nitrogen management system involves economy wide inventory of the nitrogen cycle and definition of the risk areas in the Gulf of Riga catchment where to act. This means the development and implementation of the model that follows the Impact-Pathway-Source approach to propose the most cost-efficient and effective measures for increasing the efficiency of use of N and reducing N losses. The new Integrated Nitrogen Management system, to be developed in current Project, will provide a harmonised framework for participating states – Estonia and Latvia, to be implemented afterwards by Estonia and Latvian authorities. The implementation will be based on the existing river basin management plans and marine strategies and in frames of the existing bilateral and regional cooperation arrangements.
Main activities of the project
- Development of methodology, to analyse the OECD research methodology and to develop analysis model suitable for Baltic Sea area
- Analysis of data, to gather data from relevant Estonian and Latvian institutions, to model data according to the agreed methodology and to evaluate and interpret research results by experts.
- Development of GURINIMAS and Dissemination of Results, to development of integrated nitrogen management system (GURINIMAS) targeted to reduce nitrogen load in Gulf of Riga and to disseminate the results of the project to target groups and stakeholders.
The Estonia-Latvia programme contributes EUR 363 196,50 EUR and partners' self-contribution is EUR 64 093,50.
