“…Steinemann (2000, p.640) defines a holistic approach as one which facilitates "moving away from analyses of isolated risks and toward a broader understanding". Most of the efforts made towards developing such approaches have come from the application of Health Impact Assessment or Social Impact Assessment, precisely because the reductionist approach requires existing knowledge and understanding amongst affected communities which is often lacking (see, for example, Arquette et al, 2002;Kemm, 2000;Mindell et al, 2001). Both Bell and Morse (2008) and Lawrence (1997) call for a more systems-based approach in order to implement holistic assessment, and this requires a process where communities are systematically involved in defining visions of sustainability and also the means to achieve the vision.…”
