Exploring Solid-Waste as an Indicator of Sustainability in Small Island Developing States (SIDS) Case Study of Tortola, British Virgin Islands (BVI) Noni Georges Islands VIII November 2004
Outline • Background Concepts • Island Sustainability • Measuring Sustainability • Waste Management • Case Study: • Study Area • Solid Waste Trends • Implications • Conclusion
Conceptual Diagram Island Sustainability Waste Management Measuring Sustainability
h Island Sustainability
Environment Open System Matter Energy Matter Energy System Boundary
Measuring Progress Commitments to: • Agenda 21 • Barbados Program of Action • St. Georges Declaration
Problem Caribbean SIDS have not yet begun to address assessing physical progress towards sustainable development
Understandable Lack research capabilities Focus on assessing vulnerabilities Regrettable Obligated to assess progress Excellent candidates for sustainable development research Silence of SIDS
Extraction Processing Production Consumption Disposal
Definition Materials that we can not or do not use
Economic Process • Depends on high quality material inputs • Converts high quality materials into low quality wastes • Environment is the source of inputs and sink for wastes
Survival of Society • Continuation of the economic process
Question I
Limitations • Accuracy • Lack of public co-operation • Weigh scale maintenance • Inconsistent record keeping • Utility • Outdated composition study • Origin of wastes unknown
Population Growth • Visitor Contribution • Local Contribution • Economic Growth • GDP • Consumption
Visitor Contribution • Overnight visitor arrivals • 365,000 - 474,000 • Effective visitor population • (number of visitors x average length of stay / 365) • 4,400 - 8,000 • Waste Generation Estimates • Land-based visitors (3.0 kg/day) • Water-based visitors (1.6 kg/day) • Cruise visitors (1.77 kg/day)
Local Contribution • Total Solid Waste – Visitor Contribution • Population Scenarios • 2% • 3.8%
Local & Visitor Waste Contribution Tons per day 1995 1997 1998 1999 2000 1996
Economic Growth • GDP $315 - $680 million • GDP / capita $18,900 - $33,700
Limited waste system capacity • Storage • Collection • Treatment • Disposal
Assimilation Capacity • Soil • Air • Water
Rest of the world Domestic Environment ECONOMIC PROCESSING Imports $1,019 million Exports $137 million DPO (86,926 t solid waste)
Increased Waste per Economic Output • Unsustainable
Tourism Carrying Capacity = F (Total waste capacity - Local needs)
Economic • Capacity to afford sound waste management system • $1.5 million • No tipping fees • No user fees • No recycling/deposit-refund scheme
Social • Lack of waste management programmes, policy, laws, regulations indicates lack of recognition that waste management failures need to be addressed • Contradicts National Policy Goal for Sustainable Development
