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。
