Key Concepts
Precautionary Principle (PP): Central to sustainability and environmental policy; emphasizes precaution in the face of uncertainty. Its exact content is often unclear.
Historical Context: Originated from German environmental legislation (Vorsorgeprinzip) in the 1970s and has evolved to become a guiding principle in international treaties.
Application in Fish Farming: Addresses the issue of escaped farmed salmon in Norway and its implications for wild salmon populations.
Sections of the Paper
1. Introduction
Discusses the shift in sustainability discourse from natural processes to human practices and technological solutions.
Emphasizes the socio-economic aspects of sustainability rather than just ecological factors.
2. The Precautionary Principle
2.1. International Discussion
Traces the development of PP through various international treaties (e.g., North Sea Ministerial Declarations, Rio Declaration).
Highlights the principle’s evolving role in environmental policy and debates.
2.2. Features of the Precautionary Principle
Relevant when facing scientific uncertainty.
Recognizes that science can never provide absolute certainty, thus justifying precautionary measures even in the absence of conclusive evidence.
3. Fish Farming and Atlantic Salmon
3.1. Background
Norway leads global salmon farming; production expected to reach 300,000 tons by 1997.
Issues include heavy antibiotic use and significant escapes (1-2 million annually).
3.2. Uncertainties Regarding Salmon Escapes
Uncertainty about the behavior of escaped salmon and the ecological impact.
Questions about potential cross-breeding with wild populations raise concerns about genetic diversity.
3.3. Conditions for Applying PP
Scientific models indicate potential harm (e.g., genetic dilution of wild salmon). Four conditions must be met to justify precautionary action:
Plausible model scenarios predicting harm.
Significant and possibly irreversible environmental harm.
Lack of immediate evidence confirming harm.
Persistent uncertainty that won’t dissipate before damage occurs.
3.4-3.7. Four Different PP Strategies
Engineering: Focus on improving technology to reduce escapes.
Pros: Technological improvements and industry cooperation.
Cons: May not prevent all escapes and relies on human operations.
Clean Technology: Advocates for land-based or genetically modified farming.
Pros: Provides more control and eliminates breeding risks.
Cons: High costs and potential public rejection of genetically modified products.
Political Steering: Regulation of fish farming locations to minimize risk to wild stocks.
Pros: Reduces risk without major industry upheaval.
Cons: Local economic impact and potential unpopularity of governmental action.
Deep Ecology: A radical approach that would ban salmon farming altogether.
Pros: Effective in preserving wild stocks and biodiversity.
Cons: Economic devastation and potential social unrest.
4. A Model Framework for Implementing PP
4.1. Beliefs as Basis for Values
Discusses how societal values and beliefs about nature influence environmental policies.
4.2. Attitudes to Risk Taking
Different willingness to bear risks affects stakeholders' preferences towards precautionary strategies.
4.3. Four Basic Value Perspectives
Political steering: Accepts moderate environmental risks for economic stability.
Engineering: Similar view, focusing on technological fixes.
Deep ecology: Seeks to eliminate all significant ecological risks radically.
Clean technology: Aims for serious measures without socioeconomic disruption.
Conclusions
The paper stresses that there is no one-size-fits-all solution to applying PP, as it intertwines with values and beliefs surrounding nature and society. A range of strategies exist, reflecting differing societal values and perceptions of risk.
Recognizes the need for more inclusive decision-making processes that engage various stakeholders in finding consensus on precautionary actions.
