Food production

After several years of pandemic-driven price spikes at the grocery store, retail food price inflation is slowing down. That’s good news for consumers, especially those in low-income households, who spend a proportionally larger share of their income on food. But there’s more to the cost of food than what we pay at the store. Producing, processing, transporting and marketing food creates costs all along the value chain. Many are borne by society as a whole or by communities and regions. For example, farm runoff is a top cause of algae blooms and dead zones in rivers, lakes and bays. And food waste takes up one-fourth of the space in U.S. landfills, where it rots, generating methane that warms Earth’s climate. Exploring these lesser-known costs is the first step toward reducing them. The key is a method called true cost accounting, which examines the economic, environmental, social and health impacts of food production and consumption to produce a broader p...

Flash droughts develop fast, and when they hit at the wrong time, they can devastate a region’s agriculture. They’re also becoming increasingly common as the planet warms. In a new study published May 25, 2023, we found that the risk of flash droughts, which can develop in the span of a few weeks, is on pace to rise in every major agriculture region around the world in the coming decades. In North America and Europe, cropland that had a 32% annual chance of a flash drought a few years ago could have as much as a 53% annual chance of a flash drought by the final decades of this century. The result would put food production, energy and water supplies under increasing pressure. The cost of damage will also rise. A flash drought in the Dakotas and Montana in 2017 caused US$2.6 billion in agricultural damage in the U.S. alone. Stunted corn in Nebraska struggles to grow during the 2012 flash drought that covered much of the cent...
