Coromandel Wakame – turning an ocean pest into a premium edible export

The small Coromandel company Wakame Fresh are turning a pest seaweed into a premium edible export.

Undaria, also known as wakame, is often referred to as ‘the gorse of the sea’. It’s one of the world’s most invasive pests. It’s also a staple part of the diet in Japan, where quality wakame is in short supply. The Wakame Fresh team are turning gorse into gourmet!Read More »

Splashing the Cash at Aquaculture

But is Aquaculture a Sunset Industry Like Oil and Gas?

In the last 12 months, we have seen overwhelming evidence that the oceans around New Zealand have been warming to an alarming degree.  Last summer we had a marine heatwave, and the latest data shows that once again the summer sea temperatures around New Zealand are extreme. So why are our rates and taxes being splashed around for aquaculture, which because of increasingly warm oceans may turn out to be a sunset industry?

Our oceans have warmed significantly in the last decade

Current Methods May Underestimate Thames’ Sea Level Rise – Study

But New Method Accurately Measures Shallow Land Subsidence

In previous posts I have highlighted how land subsidence in the Lower Firth of Thames, and along the Thames foreshore significantly increases the risk of sea level rise.  The subsidence rate has to be ADDED to the sea level rise rate.  I also posted how a recent study in San Francisco Bay calculated that the areas which could be flooded from the sea could be doubled when land subsidence is taken into account.

A new study suggests that sea level tidal gauges do not properly account for land subsidence, severely underestimating the amount of sea level rise in coastal areas like Thames and the Hauraki Plains. Read More »
