For centuries, farmers around the globe have tilled the soil to prepare for planting. Traditional tilling, however, exposes the bare earth to wind and water, causing erosion and the loss of soil organic carbon, as well as lowering soil quality and crop yields. In the US Corn Belt tilling has degraded  approximately 35% of the land– about the size of Montana. In China, erosion from traditional tilling has degraded over 50% of agricultural soils. In the two countries soil erosion and loss of soil fertility is creating annual economic losses of $1.9 billion and $3.7 billion, respectively. Nevertheless, farmers are often hesitant to switch to no-till practices.

Extreme heat from climate change threatens food security in the world’s two food-producing superpowers. Climate adaptation for agriculture is a must. The US and China have much to share on climate-smart farming practices to help us both weather the storms and droughts. 2023 brought scorching heat waves that baked crops and livestock in China and the United States. In China, farm animals and fish died from extreme heat in June with some provinces enduring weeks of temperatures above 40°C (104°F). In one farm, a heatwave-triggered power outage resulted in hundreds of pigs suffocating to death after shed fans stopped working.
