<p></p><p>Sweet potatoes, among the most nutritious vegetables in the world, are threatened by climate change and pests. Researchers recently evaluated dozens of sweet potato studies to identify the challenges, opportunities, and threats to this healthy and productive crop. Sweet potato crops remain vulnerable to extreme weather, pests, diseases, and storage problems, and this research, published in <i>Agronomy Journal</i> in February, collects the most successful responses to these challenges (https://doi.org/10.1002/agj2.21539).</p><p>More research is needed on non-pesticidal approaches to pest and disease control because pesticides are expensive, harm the environment and consumers, and increase market prices. Most current research is done on big corporate farms, making it harder for low-income growers to know how to protect their sweet potatoes.</p><p>One big problem is that, due to high harvesting costs, sweet potatoes below the U.S. No. 1 grade aren’t even harvested. One study estimated that 125 million kg of sweet potatoes in North Carolina alone went unharvested in 2016.</p><p>The sweet potato market is worth around $600–700 million annually. Keeping growth sustainable will require more food science research, consumer studies, new technologies, and identification of the traits that make sweet potatoes better for consumers.</p><p>Despite all this, sweet potato production in the United States is diminishing due to high labor costs, unavailability of seeds and bulbs, and insecticide-resistant pests. Climate change has caused droughts and higher carbon dioxide levels, which hinder the growth of sweet potatoes, and while pest-resistant breeds exist, they don’t have as many of the qualities that consumers like the most.</p><p>To make sweet potato farms more cost-efficient and eco-friendly, farmers are using water more efficiently. Sweet potatoes can resist droughts, but other than that, farmers don’t know much about their exact water requirements.

Agriculture in the United States faces significant challenges, including food insecurity, climate change, environmental degradation, and rural prosperity issues. The USDA Long-Term Agroecosystem Research (LTAR) Network, which comprises 18 national sites, aims to address these challenges through sustainable intensification. Each site conducts a “Common Experiment” to compare traditional management practices with new alternative strategies. Upcoming special sections in the Journal of Environmental Quality will highlight the LTAR Network’s work and progress in implementing these experiments nationwide.
美国农业面临着重大挑战，包括粮食不安全、气候变化、环境退化和农村繁荣问题。美国农业部长期农业生态系统研究（LTAR）网络由 18 个国家站点组成，旨在通过可持续集约化应对这些挑战。每个研究点都开展 "共同实验"，将传统管理方法与新的替代战略进行比较。环境质量期刊》（Journal of Environmental Quality）即将推出的专栏将重点介绍 LTAR 网络的工作以及在全国范围内实施这些实验的进展情况。
