Figure 12.1 Criteria for selecting options

Textual description

This figure summarises the criteria for selecting options. A system approach is about selecting the option that best fits the total natural and human ecosystem within which it is embedded. The human system includes individual developments, governing systems and social/cultural systems – all of which are interlinked and all link to the funding and economic system and infrastructure. Questions to be considered include: (from individual development) Does it achieve integration with the water web and 3-waters? How does it impact on individual members of the community? Is it resilient to natural hazards? What are the total and ongoing costs and how will it be funded? (from governing system) What are the impacts on the ecosystem services? What are the management requirements and are they appropriate? (from social/cultural system) Does it protect public health? Does it meet social and cultural criteria? Does it meet existing and changing expectations, needs and minimise risk? How well does the option manage environmental impact residuals?
