Where can flooded fields help replenish groundwater?

Overpumping in California’s Central Valley has depleted groundwater storage capacity and caused the land to sink. A new model could help zero in on where water managers can replenish aquifers by flooding fields.

Farming for natural profits in China

Expanding monoculture threatens valuable services from land, such as flood control, water purification and climate stabilization. Gretchen Daily and Hua Zheng are promoting a new approach.  

Hot, dry years will hit many regions simultaneously

Odds are rising that warm, dry conditions – the kind that can hurt crop yields, destabilize food prices and exacerbate wildfires – will strike multiple regions at once. A new Stanford study shows just how much the risk is increasing.

Students cultivate positive connection with land through new course

In a new course at the Stanford Educational Farm, students develop a positive relationship with the land through organic gardening while addressing the history of forced farm labor in the U.S. and its enduring, traumatic effects on communities of color.

Tracking fishing from space

Satellite data from thousands of high seas fishing vessels over four years illuminate global fishing’s scope and pattern and hold promise for improving ocean management across the planet.

Corporate sustainability often less than meets the eye

The first large-scale analysis of corporate practices for sourcing sustainable materials shows that many companies address sustainability at some level, but most deal with only one or a subset of materials within a small portion of their supply chain.

Change behaviors by changing perception of normal

In a study, people ate less meat and conserved more water when they thought those behaviors reflected how society is changing. The findings could point to new ways of encouraging other behavior changes.

Microbes in flower nectar affect pollination

Stanford’s community ecology lab has found that microbes in nectar can affect bird and insect interactions with the flowers and, as a result, whether they get pollinated.
