A RESILIENT STRATEGY

THE EDGE

How can we engage both human and non-human communities along The Bay’s water edge to create a resilient urban water management strategy?

THEORY

URBAN WATER MANAGEMENT

URBAN WATER MANAGEMENT

water security through industry function lacks community engagement

efficiency of function

vulnerable to climatic changes and pollution

protection of assets against flooding neglects ecological communities

NON-HUMAN COMMUNITY

Indicators: Clean water environment as they are filter feeders

Habitat: Salty/brackish waters

Diet: Phytoplankton or small bits of algae

Reproduction: Annually spawn from the end of June - mid-August

Indicators: Clean water environment as they are particularly sensitive to pollutants

Habitat: Reefs/Sea Grass

Diet: Algae, diatoms and small detritus particles

Reproduction: Annually spawn in Mid January

Indicators: Clean water environment as they are filter feeders (in higher population numbers because of industrial polluants)

Habitat: Reefs, piling and hard surfaces

Diet: Plankton and detritis

Reproduction: Annually
