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

11 existing plans and guidelines 2008 USEPA Planning for Natural Disaster Debris

12 existing plans and guidelines 2011 UNOCHA Disaster waste management guidelines

13 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.

14 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

15 waste characteristics - quantity 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.

17 operational strategies

18 operational strategies - collection Hurricane Katrina kerbside collection Photo credit: Tim Townsend, University of Florida

19 operational strategies - collection 2009 Samoan tsunami clean-up

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

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

22 operational strategies – treatment reuse / recycling waste to energy incineration

23 operational strategies – final disposal Lyttelton Port Reclamation Christchurch, 2011

24 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

25 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
