Modellering av miljøtilstanden i indre Oslofjord sett i lys av utslippstillatelser og befolkningsutvikling

Abstract

Miljøtilstanden i Indre Oslofjord innenfor Drøbak har blitt modellert med NIVA Fjordmodell. Nå i 2020 bor det 1 million mennesker i kommunene rundt Indre Oslofjord, og det har blitt antatt at denne befolkningen vil øke til 1,25 millioner i 2040 og til 1,48 millioner i 2060. Denne befolkningsøkningen gir generelt en økning i mengden planteplankton i overflatelaget, gitt at dagens rensegrad opprettholdes, og at det ikke er noen økning av tilførsel til overflatelaget. Ifølge modellen vil det i Vestfjorden være omtrent like mye planteplankton i 2060 som det var på 90-tallet. Resultater fra modellkjøringene indikerer at det ikke vil være mulig å bedre vannkvaliteten i overflatelaget kun ved å opprettholde dagens rensegrad med en slik befolkningsøkning som er skissert her.
