  • US Agricultural Success Built on US-China Scientific Exchange

    China Environment Forum  //  Cool Agriculture  //  Guest Contributor  //  December 5, 2024  //  By Karen Mancl

    “History teaches that China and the United States gain from cooperation and lose from confrontation” was part of the congratulatory note from Xi Jinping to President-elect Trump. Xi also stressed both sides should continue to uphold “mutual respect, peaceful coexistence and win-win cooperation.” The cooperation between these two superpowers began in 1972 when President Richard Nixon and Premier Zhou Enlai signed the Shanghai Communiqué, years before they established diplomatic relations.

  • Food Waste: A Low-Hanging Fruit for Methane Reductions

    ›
    China Environment Forum  //  Cool Agriculture  //  February 8, 2024  //  By Jennifer Nguyen, Jennifer Turner & Karen Mancl

    This blog is modified from the Wilson Center-OSU “Cultivating US and Chinese Climate Leadership on Food and Agriculture Roadmap” publication. 

    “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 Commune in Rural Iowa Inspires Reform in China’s Countryside

    China Environment Forum  //  Cool Agriculture  //  Guest Contributor  //  January 18, 2024  //  By Karen Mancl

    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.

  • No Water, No Food – Glacier Loss Threatens US and Chinese Agriculture

    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’s Key Role in Fighting Climate Change in U.S. and Chinese Agriculture: The Wisdom of Dr. Rattan Lal

    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.

  • Rice: A Recipe for Greenhouse Gas Emissions in the U. S. and China?

    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.

  • The Forgotten Greenhouse Gas: Nitrous Oxide as an Issue for U.S. and Chinese Agriculture

    During the November COP27 climate talks in Egypt, Presidents Xi and Biden agreed to restart bilateral climate talks that would build on the clean energy and the green and climate-resilient agriculture priorities highlighted in the U.S.-China Climate Crisis Statement and the U.S.-China Glasgow Declaration. While details remain to be ironed out, the renewed dialogue could open up a new area of collaboration around greenhouse gas emissions from food production, targeting an oft-overlooked long-lived climate pollutant, nitrous oxide (N2O).
