In recent years, a new narrative has appeared on Chinese social media: that a warmer and wetter climate in Northwest China will herald a return to the “golden age” of the Tang dynasty (618–907 AD). 

Climate change will bring benefits, so the story goes, as historically China has flourished during warmer and wetter periods – conditions becoming common once more in the Northwest, a region extending from the province of Shaanxi to Xinjiang in the far west.

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.  

When Kevin Chen began his agricultural research 20 years ago, most dairy farms in China were small and family-owned. People of his generation did not grow up with milk deliveries or ice cream. Today, however, these farms have been replaced by massive agri-businesses raising tens of thousands of dairy cows, and dairy is a regular part of many people’s diets in China, thanks to rising incomes and years of governmental promotion of cheese, yogurt, and milk. 

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.
