This award funds a large scale effort to collect new data about the determinants of agricultural productivity in the United States during the 20th century. The PIs are combining information from several archival sources to compile a single dataset that includes data from over 3000 US counties, collected annually from 1879 to 2002. With these data, the PIs examine the effects of changes in climate and weather on agricultural productivity. They also examine the impact of R&D spending (at the national, state, and local levels), better education and training for farmers, new technologies, and government programs intended to aid agriculture. The data sets collected create substantial broader impact; they will be used by a large interdiscplinary research community because they can be sued to study a wide variety of socio-economic issues in rural areas. The data will also help us to understand and predict the effects of climate change on agricultural productivity.

该奖项为20世纪美国农业生产力的决定因素收集新的数据提供了大规模的努力。 PI将来自几个档案源的信息组合在一起，以编译一个包含来自3000多个县的数据，从1879年到2002年收集的单个数据集。通过这些数据，PIS研究了气候和天气变化对农业生产率的影响。 他们还研究了研发支出（在国家，州和地方一级），为农民，新技术以及旨在帮助农业的政府计划的更好的教育和培训的影响。收集的数据集会产生更广泛的影响；它们将被大型跨跨研究社区使用，因为他们可以被起诉研究农村地区的各种社会经济问题。 数据还将帮助我们理解和预测气候变化对农业生产力的影响。
