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:

    1. Plausible model scenarios predicting harm.

    2. Significant and possibly irreversible environmental harm.

    3. Lack of immediate evidence confirming harm.

    4. Persistent uncertainty that won’t dissipate before damage occurs.

3.4-3.7. Four Different PP Strategies
  1. 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.

  2. 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.

  3. 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.

  4. 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.
