2 Baggrund Trusler fra flere fronter: Lav pris konkurrence; Asien mm. Europæisk og national lovgivning: Miljø Kvalitet Sundhed Udgangspunkt i 5 case studier Switzerland: Tilapia Overskuds varme Poland: Alm. Karpe Ungarn: Afrikansk og Europæisk catfish/malle Holland: Tilapia Denmark: ørred
3 Consortium 10 IAGs 6 SMEs 7 RTDs 12 lande
4 Objectives Miljø WATER NUTRIENT Genbrug af vand Lokal klima stabilitet Reduktion af spidevand/udledning Bedre benyttelse af næringsstoffer Reduktion i udledning ENERGY Reduktion af energi behov
5 Objectives Økonomisk dimension MARKETS PROFITABILITY Diversify markets/ products/ services Højkvalitetsprodukter Forbedre forbrugernes accept Bæredygtighed for management Reducerede omkostninger til energi, vandbehandling. Fiskefoder og ferskvand Forbedret vækst Reduceret arbejdsomkostning pr kg fisk
6 Objectives Social dimension NUTRITION Sunde og næringsrige fisk EMPLOYMENT RURAL DEVELOPMENT TRADITION/ CULTURE
7 Objectives Bæredygtighedsindikatorer: Miljø, økonomisk velfærd, social Store forskelle Ekstensiv >< intensiv Hvad er bæredygtigt? Energi Indikatorer: Energiforbrug pr. tons fisk produceret Anvendt energiform Bæredygtig vedvarende energi / selvproducerende
8 Energi - SustainAqua Vindenergi: Mini vindmøller, husstandsmøller, max. 25 m, max 25 kwt Tilknytning fritliggende ejendomme landzonetilladelse (støj) Større vindmøller: Hav statsplanlægning Land kommuneplan, VVM mm. Solenergi: Solfangere varme Solceller energi?? Måske fremtidig mulighed Vandkraft?.
9 It is not just about fish... but it opens (fish)farmers new options to sustainably develop value added
10 Schweiz - Case study - Væksthus Tropenhaus Ruswil the Swiss pilot case study (1500 m2, since 1999) Gaskompressorstation naturgaspipelinien, Holland til Italien
