In desert suburb, homes in homeowners’ associations use less water, study finds
A new study finds that in a Phoenix suburb, homeowners’ associations are good for water conservation. According to the study, homes in HOAs in Goodyear, Arizona use up to 17,000 fewer liters of water (4490 gallons) in the peak month of July compared to their non-HOA counterparts, roughly the amount needed to fill eleven hot tubs.

High water tables can be a boon to crop yields
High water tables can be a bane to crop yields, compelling many farmers to drain their fields so their crops don’t drown when it rains.
But a high water table may not always be a bad thing. A new study shows it is actually a boon for some fields and during certain times of the growing season, casting light on opportunities for improving yield efficiency to meet global food demands.

How rain falls – not just how much – may alter landslide risk
New research finds that it’s not just the amount of rain that falls on a hillside, but the pattern of rainfall that matters when trying to determine how likely a slope is to give way. This new information could improve forecasts of landslides, which are typically hard to predict, said the scientists conducting the research.
Different rainfall patterns—a short, heavy deluge, a light, steady downpour, or sporadic showers—will trigger different numbers of landslides with varying amounts of debris, according to the new study published today in Water Resources Research, a journal of the American Geophysical Union.

Snow photos sought to illuminate snowmelt puzzle
In some places, where trees protect snow from sun and wind, it actually melts faster than in open areas. That’s what scientists concluded recently when they did a review of global data about snowmelt. Now, to gather much more data needed to deeply understand the discovery, and to make it useful for land and forest management, those same scientists are reaching out to an unlikely pool of collaborators: hikers, forest managers and other outdoors enthusiasts throughout the Pacific Northwest.
