Monitoring our land and water

Monitoring our land and water can range from tracking greenhouse gas emissions to extinct birds.

In this edition, we explore how researchers are monitoring our waterways on the ground and from space. We head to the Northern Territory to discover how to off-set emissions from proposed onshore gas development. 

On an international scale, we discover how many species of elephant birds existed on the Island of Madagascar and how to reduce plant pest and disease risks related to trade.

We hope you enjoy the latest sustainability stories from CSIRO.

AquaWatch: the ‘weather forecast for water quality’ that’s an Australian world first

Satellites and high-tech sensors are revolutionising the way water quality challenges will be monitored and responded to into the future.

Eggshells tell story of extinct elephant birds

How many species of elephant birds existed on the Island of Madagascar? The answer may lie in the eggshells they left behind more than 1000 years ago.

Offsetting emissions from proposed onshore gas production

Meeting net zero targets will require mitigating and offsetting greenhouse gas emissions from proposed development in the Northern Territory.

New markets on the menu with plant biosecurity tool

A new science-backed tool makes it easier to select measures to reduce plant pest and disease risks related to trade. The tool opens up more options for farmers to protect biosecurity with less reliance on chemical treatments.
