We can feed a growing population while shrinking fertilizer pollution. Here’s how.

Farmers must estimate how much fertilizer and other inputs their crop will need in the face of increased weather variability.

Nitrous oxide might not make the news like carbon dioxide, but it’s a powerful hidden force behind the extreme, climate-driven weather we’re experiencing. This super-pollutant is the third most significant greenhouse gas, with a warming impact almost 300 times greater than carbon dioxide. Lowering it is essential for avoiding the most dangerous climate impacts.

The newly released “Global Nitrous Oxide Assessment” confirms a sobering reality: atmospheric concentrations of the gas are rising faster than previously anticipated. The majority of nitrous oxide emissions come from synthetic fertilizer and manure. Yet nitrogen applications are also essential for producing the crops that feed a growing population.

We don’t have to choose between food security or climate stability. We can and must support farmers in achieving both priorities.

Reducing nitrous oxide emissions isn’t just possible — it’s within reach.

A combination of existing strategies could slash global nitrous oxide emissions by over 40%, but scaling these solutions requires commitment and innovation, but scaling these solutions requires commitment and innovation.

Despite drought, California agriculture is doing well. But there are hidden costs.

Water scarcity has affected California vineyards

According to a new World Bank report, regions around the world could gain or lose up to 6 percent of their GDP by 2050 depending on how they manage for climate-driven water scarcity.

I was curious about how the report’s findings might apply to California, where I live.

Here in the Golden State, water scarcity is a familiar threat. And while the World Bank found that climate-water costs to North American GDP should be minimal, many Californians have suffered acutely from sustained drought.

In some cases, however, it isn’t entirely clear what the impacts of water scarcity have been. Read More »
