“Waste is something that most of us just don’t see,” stressed Pete Pearson, Senior Director, Food Loss and Waste, WWF, at a recent Wilson Center event. Though people are “conditioned” to be blind to food waste, continued Pearson, this not-so-invisible problem wastes a third of food grown around the world. When this wasted food decomposes, it emits methane, accounting for 8 to 10% of global greenhouse gas (GHG) emissions.

A quiet agricultural community in east, central Iowa is a surprising place to learn about the evolution of communes in the United States. While a graduate student at Iowa State University, I first visited the Amana Colonies in 1979. The brick homes, the woolen mill, and the community kitchens were first built in 1855 by a group of German immigrants, forming the now oldest commune in the country.

Picture this: A parade of yaks carrying insulated boxes containing meter-long ice core samples from Tibetan glaciers. “Yaks are like cats,” elite glacier scientist Lonnie Thompson explained in a 2023 Wilson Center webinar. They like to wander off — and it takes experienced Tibetan yak herders to keep them moving in the same direction. 

Yet these yak-schlepped ice cores are essential to climate science, added Ellen Mosely Thompson. They store thousands of years of atmospheric dust and gasses in distinct layers and serve as a record of our changing climate.

“Save your kitchen scraps to feed the hens,” urged a poster for the victory gardens created on the home front in the Second World War. Feeding food scraps to backyard chickens and pigs turned this waste into a delicious source of human food. Pigs were especially prized in this effort as they would eat what most other animals considered inedible.

Soil degradation affects one-third of the Earth’s surface, triggering dust storms, floods, and landslides. It is also a global threat to our food supply, and diminishes the soil’s ability to sequester carbon to mitigate climate change. China has only 0.21 hectares of agricultural land per person, which is well below the global average. Worse yet, over 40 percent of that land is already degraded.  

Go to the Arkansas Rice Festival in Wiener, Arkansas and you will discover how delicious – and diversely flavored – this cereal grain can be. Savory, sweet, or even spicy: Each dish at the festival’s annual rice recipe contest shows the many ways to prepare this international food staple.

Why look to Arkansas for rice? The state produces 4 million tons of it every year, which is nearly half the rice grown in the United States.  But that U.S. annual total is dwarfed by the amount produced by China, which at 207 million tons is the world’s largest rice producer.  It’s also natural that the world looks to China for rice; genomic mapping has suggested that cultivated rice was first grown in the Pearl River valley in southern China.
