Flood innovation

Jeremy Stewart, Whian Whian

I am surprised that the pre-eminent flood mitigation proposals for Byron Shire reported in the recent Echo article are a parade of conventional engineering modifications.

Caution: historical experience of these kind of solutions to flooding has proved that they are expensive and of limited effect, that they impact elsewhere, and givepeople a false sense of security.

It’s time a more holistic approach was taken, which improves human impacts throughout the catchment, and sets the scene for a whole range of more desirable social, economic and environmental benefits and innovation.

In the upper catchment, landholders could be incentivised and supported to slow water runoff and increase soil absorption of water through measures such as reforestation, riparian enhancements, improved pasture management, improved orchard floor management and leaky ponds.

In the lower catchment, we could enhance, reinstate or construct wetlands for water control, habitat, recreation, tourism, alternative systems of agriculture and aquaculture.

Urban areas could be supported to install slow-release stormwater retention systems, planned to let the water through, and promote other development controls that reduce runoff such as porous surfaces and soakage pits.

Please, let’s encourage a bigger conversation, and see water for what it is – a magical blessing rather than something we need to get rid of as quickly as possible.

The Echo has never underestimated the intelligence and passion of its readers. In a world of corporate banality and predictability, The Echo has worked hard for more than 30 years to help keep Byron and the north coast unique with quality local journalism and creative ideas. We think this area needs more voices, reasoned analysis and ideas than just those provided by News Corp, lifestyle mags, Facebook groups and corporate newsletters.

The Echo is one hundred per cent locally owned and one hundred per cent independent. As you have probably gathered from what is happening in the media industry, it is not cheap to produce a weekly newspaper and a daily online news service of any quality.

We have always relied entirely on advertising to fund our operations, but often loyal readers who value our local, independent journalism have asked how they could help ensure our survival.

Any support you can provide to The Echo will make an enormous difference. You can make a one-off contribution or a monthly one. With your help, we can continue to support a better informed local community and a healthier democracy for another 30 years.”
