Giulio Boccaletti: What Scientific Idea is Ready for Retirement?

In hydrology, a concept known as stationarity allows us to define events using time statistics, like the “one in a hundred years flood.” Dr. Giulio Boccaletti argues that it’s time to retire this concept.

Re-Branding Nature: From Dismal Swamp to Constructed Wetland

Swamps were once considered disease-ridden, alligator-infested places. Now they’re hailed for the ecosystem services they provide–but for that image to stick, constructed wetlands have to be based on the best-available science.

Farming, Adapting to Climate Change & the Limits of Imagination

A new study from Conservancy scientists says irrigation needs are going to increase significantly under future climate change projections. Can farmers be equally radical in how they respond to these drier conditions?

Quick Study: How Will Climate Change Affect Irrigation of Farm Lands in U.S.?

Quick Study is just what it says — a rapid-fire look at a new conservation science study that might turn some heads.

The Study: McDonald, R. and E. Girvetz. 2013. Two challenges for U.S. irrigation due to climate change: increasing irrigated area in wet states and increasing irrigation rates in dry statesPLoS ONE 8(6): e65589. doi:10.1371/journal.pone.0065589.

The Questions: Climate change models forecast higher average temperatures that will cause crop-growing seasons in the United States to become hotter and drier. How will this impact the irrigation needs of agriculture in the United States? And how will farmers respond to drier conditions?

New Study: How Cities Can Finally Get Smart About Water

If the definition of insanity is making the same mistakes over and over, then many cities have taken a certifiable approach to securing their water supplies — and they need some radical therapy before taking the big economic, ecological and human hits that come with a permanent state of thirst.

That’s the conclusion from a new study in the journal Water Policy, whose authors compared the water supply histories of 4 cities — San Diego, Phoenix, San Antonio and Adelaide, Australia. Among the lessons learned? Urban water conservation, recycling and desalination aren’t silver bullets. In fact, the best solution may lie upstream with farmers — saving just 5-10% of agricultural irrigation in upstream watersheds could satisfy a city’s entire water needs.

Brian Richter, a senior freshwater scientist at The Nature Conservancy and the study’s lead author, told me more about what cities need to do to say on the right side of dry.
