KEEPING AN EYE: A Goanna Ag canopy sensor on a tomato crop near Swan Hill, Victoria.

The CSIRO and local agtech company Goanna Ag have teamed up to give irrigators the technology to get maximum value out of every drop of water.

They are claiming WaterWise will be Australia’s only water-use efficiency product for irrigated crops that measures crop water stress and predicts future water needs in real time.

Case study suggests new approach to urban water supply

Graphic: MIT study on water infrastructure

If you live in the developed world, safe water is usually just a faucet-turn away. And yet, global warming, drought conditions, and population growth in coming decades could change that, ushering in an era of uncertain access to water.

Now an MIT-based research team has evaluated those potential problems and, based on a case study in Australia, suggested an alternate approach to water planning. In a new paper, the researchers … [more…]

Spiders, such as the one pictured here, are found in riparian environments all over the world. They build their webs over streams and catch aquatic insects as they emerge from the water. Pharmaceuticals in the insects spread to the spiders and other organisms on land. Photo: Stephen Hamilton

Medicines do an excellent job of increasing the quality of life for humans around the world, but the drugs don’t stay with

Water shortages key environmental challenge of century, NASA warns

Water shortages are likely to be the key environmental challenge of this century, scientists from NASA have warned, as new data has revealed a drying-out of swaths of the globe between the tropics and the high latitudes, with 19 hotspots where water depletion has been dramatic.

Areas in northern and eastern India, the Middle East, California and Australia are among the hotspots where overuse of water resources has caused a … [more…]
