Developing a Sustainable Water Footprint Program for Marine Aquaculture

This discussion focuses on the goal of creating a Sustainable Water Footprint Program (SWFP) for marine aquaculture, addressing a broader range of drivers impacting marine waters such as tourism, shipping, oil production, and pollution. The aim is to develop tools for decision-makers to assess the environmental sustainability of aquaculture, comparing industries and measuring water usage, pollution, and impacts on ecosystems and human health. The workshop seeks insights on necessary expertise, institutional involvement, and funding strategies to advance this initiative.

  1. SWFPQuestions for discussion

  2. What is the Goal of a SWFP? • Focusonexclusivelyon marine aquaculture? • Broader? Country SWFP for all «drivers» thataffect marine waters – • Tourisim, shipping, oilproduction, fishing, etc • Point and non-pointsourcepollution (Cities, agriculture, industrialetc)? • But: withaquaculture as a first step?

  3. Uses, continued • Createtool for decision-makers? • Createmeasure for comparingindustries? • Answer questions abouthowenvironmentallyfriendlyaquacultureactually is?

  4. Rank/rate firms/types/countries for: • How much marine water used in production? (classicfootprint) • Buthowmuch is removed? • SW dependency (internal/external) • Efficiencyof water use? • Impacton water quality? • Pollution/water required to diluteeffects? (Gray) • Impactonneighbors? • Impactonecosystem and/or human health? • Impactofaquacultureonother water-dependent industries? • Possible positive benefits? • With respect to alternatives?

  5. Shouldweinclude a measureof… • Loss of habitat? • Impactonecosystem? • Removalof water? • Evaporation? • Impactonground water? • How muchusuage/pollutionetccontributes to conflict? (at a later stage?)

  6. Or do wewantanother sort offoodprint for aquaculture? • Protein footprint? • Existingfootprints – • Ecologicalfootprint • Energy/Carbon • Nitrogen footprint (from DG Environment News Alert Service) • http://ec.europa.eu/environment/integration/research/newsalert/pdf/278na3.pdf • Biodiversityfootprint • http://www.guardian.co.uk/sustainable-business/biodiversity-footprint-new-carbon-measurement-management • Food footprint • http://www.globalfootprints.org/issue/food/

  7. Whatarethe problems involved in developing a SWFP?

  8. Concepts to keep in mind • Blue/Green/Gray water • Regionalization • Effectsofany given usewillvary by location • Pathways • How SW useimpacts «X» • In- and off- «stream» usage • Consumptive vs. Degradativeuse

  9. Whatexpertise do weneed for thisproject?

  10. Whatinstitutions do wewant to include? • Trondheim preference? • Business/industry? • Relate to whatexpertiserequired

  11. Fundingideas • Depends on type ofprojectweselect

  12. The Way Forward • Do wewant to go forward? • Circulate report from this workshop • Assigntask for … • New workshop? Or proposals to circulate?
