Socio-cultural valuation of ecosystem services provided by Baltic Salmon Timo P. Karjalainen Thule Institute/University of Oulu Oulun yliopisto
Sisällys/content The issue (kysymys): how to value and assess incommensurable and contested criteria in salmon management (miten arvottaa ja arvioida yhteismitattomia ja kiistanalaisia asioita/tekijöitä lohivarojen hallinnassa)? 1. Baltic Salmon fisheries governance 2. Ecosystem services and valuing of the benefits provided by salmon (ekosysteemipalvelut ja lohen tuottamien hyötyjen arvottaminen) 3. Co-management instutions the need (Kuinka arvioida ja arvottaa hyötyjä loheen liittyvässä päätöksenteossa?)? Future of the wild salmon stocks, Tornio 2012 1
Baltic Salmon fisheries governance: changes in interests and management Originally spawned in 100-120 rivers, now 30 ( 2 in Finland) During 1900s the number of salmon rivers decreased rapidly (dams, habitat degradation, overfishing) Fishing has continued, mostly based on releases of hatchery-reared salmon Farmer s approach: sea as a field (commercial food production) mostly marine or coastal fisheries management Environmental objectives and priorities from the late 1990 s Salmon Action Plan 1997-2006: overall goal was to restore salmon populations of selected rivers to at least 50% of the potential capacity by the year 2010 (stocking activities, restoration, fishery regulation) WFD, Habitat Directive (objectives for modified rivers also) Commercial catches are decreasing (drifnet ban 2008), and fisheries interests are increasingly heterogenous: commercial, recreational, environmental Management shift from marine mix-stock management towards stock based (river origin) management?? On the coastal areas salmon is still important catch for commercial fishers while inhabitants of the river areas see salmon as an essential element in developing tourism around recreational fishing. more salmons to river (also modified) distributional conflict what are the benefits and losses for different groups) what are the salmon ecosystem services?
Ecosystem services Ecosystem services are the benefits people obtain from ecosystems(ks. MEA 2005) Provisioning services (e.g. food and water) Regulating services (e.g. regulation of floods and disease Supporting services (e.g. soil formation and nutrient cycling) Cultural services (recreational,spiritual, religious and other nonmaterial benefits) 3
