More and longer heat waves are coming, so researchers are making sure our crops are ready. Amy Mergard

Can crops withstand more heat waves?

Australia broke its “hottest day” record this week, and heat waves are becoming more common in Australia. Heat waves are projected to increase in duration and intensity with global warming and climate…

Agriculture’s hunger for nitrogen oversteps planetary boundaries

Planet Earth has boundaries for its biophysical subsystems. By 2009, we had already exceeded three of the boundaries – climate change, biodiversity loss, and the nitrogen cycle. Climate change is a top-of-mind…
Flooding risk is often used as an argument against greater environmental flows for the Murray-Darling, but graziers would benefit greatly from floods. Richard Kingsford

More flooding in the Murray-Darling basin could be good news for farmers

The history of our development of the Murray-Darling Basin is one of constraining and constricting its rivers’ flows. Many of the basin’s floods are now captured in dams for later constrained release to…
