  8. social impact Why is good disaster waste management important? economic impact environmental impact background

  9. existing plans and guidelines 2008 USEPA Planning for Natural Disaster Debris http://www.epa.gov/wastes/conserve/imr/cdm/pubs/pndd.pdf

  10. existing plans and guidelines 2011 UNOCHA Disaster waste management guidelines www.ochanet.unocha.org/p/Documents/DWMG.pdf

  11. existing plans and guidelines • current planning focusses on operational aspects. • it is challenging to plan for a very wide spectrum of disaster impacts. • a possible approach is to use disaster waste ‘indicators’ (see Brown, 2012 thesis, for more detail) • disaster scale • number of displaced persons • geographical extent of damage • duration of hazard event • damage to road network • volume of waste • human & environmental health hazards • movement of the waste (from point of origin), and • difficulty in handling the waste.

  12. waste characteristics - composition typical types of waste • vegetative • construction and demolition • personal property / household items • household hazardous wastes • white goods • soil, mud and sand • vehicles and vessels • putrescent

  13. how much waste? • varies widely between different disaster types and built environments. • FEMA have developed some waste estimation tools (FEMA, 2010, Debris Estimating Field Guide and FEMA, 2009, Multihazard loss estimation methodologies). • UNEP are currently developing some debris estimating tools. • some models have also been developed in Japan. waste characteristics - quantity

  15. operational strategies

  16. operational strategies - collection Hurricane Katrina kerbside collection http://www.ees.ufl.edu/homepp/townsend/disaster/DD_Overview.pdf Photo credit: Tim Townsend, University of Florida

  17. operational strategies - collection 2009 Samoan tsunami clean-up

  18. operational strategies – handling Temporary storage in rice paddies and mangroves, following the 2004 Indian Ocean tsunami

  19. operational strategies – handling Space needed: 50ha per 1,000,000 cu.m debris 2007 FEMA Debris Management Guide

  20. operational strategies – treatmentreuse / recyclingwaste to energy incineration

  21. operational strategies – final disposal Lyttelton Port Reclamation Christchurch, 2011

  22. management considerations • overall management and coordination: link with recovery authority • human resources: skilled and unskilled work, livelihood and capacity building opportunities • public participation • public communication • human health and environmental risk management: accept there will be higher risks • laws and regulation: flexible and bounded • funding – public vs private

  23. disaster waste has a significant impact on a community's social, economic and environmental recovery. • flexible planning is needed. • both operational and management aspects need to be considered. summary
