Long-Term Agroecosystem Research Network regions, 2018 version

The Long-Term Agroecosystem Research Network, consisting of 18+ research locations, is conducting research on the sustainable intensification of agroecosystems. To enable coordinated network level research, a spatial framework is required to facilitate analysis. However, no suitable spatial framework currently exists to meet the needs for the LTAR Network. To develop a framework for analysis the LTAR Network initiated the Regionalization Project. Goals also included providing a standardized spatial footprint for LTAR cross-site investigations, estimating the confidence with which results from research plots and fields could reasonably be extrapolated to "represented regions", informing decisions about where additional research sites should be prioritized and facilitating public outreach of the LTAR Network. To address these goals a workshop was held in 2018 resulting in the production of three sets of regional boundaries in a geographic information system (GIS). These GIS datasets are intended to be used for mapping the
network and for summarizing spatial data relevant to domains of sustainable intensification corresponding with agricultural production, environmental impact, and rural prosperity. This resulted in a geodatabase of three new maps describing regional boundaries for the LTAR Network titled "Long-Term Agroecosystem Research Network regions, 2018 version", archived in the USDA National Agricultural Library's Ag Data Commons repository. Resources in this dataset:Resource Title: LTAR_Regions_v2018. File Name: LTAR_Regionsv2018.gdb.zipResource Description: Geodatabase of the regions pertaining to the Long-Term Agroecosystem Research Network. There are three data layers describing regions associated with indicators of sustainable intensification corresponding with agricultural production (LTAR_Production_v2018), environmental impacts (LTAR_Environment_v2018), and rural prosperity (LTAR_RuralProsp_v2018). These date were produced by the LTAR Regionalization Project as an outcome from the 2018 LTAR Regionalization Project workshop held in March 2018, Tifton, GA.Resource Software Recommended: ArcGIS Pro,url: www.esri.com

长期农业生态系统研究网络，由18个以上的研究地点组成，致力于农业生态系统的可持续强化研究。为促进网络层面的协同研究，需要一个空间框架以支持数据分析。然而，目前尚无合适的空间框架能够满足长期农业生态系统研究网络的需求。为此，长期农业生态系统研究网络启动了区域化项目，旨在开发一个分析框架。项目目标还包括为长期农业生态系统研究网络的跨站点研究提供标准化的空间足迹，估算从研究地块和田野中得出的结果可以合理外推至“代表性区域”的置信度，为决定优先考虑新增研究地点提供信息，并促进长期农业生态系统研究网络的社会公众宣传。为实现这些目标，2018年举办了一次研讨会，最终在地理信息系统（GIS）中产生了三套区域边界。这些GIS数据集旨在用于绘制网络地图，以及总结与农业生产、环境影响和农村繁荣相关的可持续强化领域的空间数据。这导致了一个地理数据库的建立，其中包含三张描述长期农业生态系统研究网络区域边界的地图，题为“长期农业生态系统研究网络区域，2018版”，并存档于美国农业部国家农业图书馆的农业数据共享库中。本数据集中的资源包括：
资源标题：LTAR_Regions_v2018
文件名：LTAR_Regionsv2018.gdb.zip
资源描述：与长期农业生态系统研究网络相关的区域地理数据库。包含三个数据层，描述与农业生产（LTAR_Production_v2018）、环境影响（LTAR_Environment_v2018）和农村繁荣（LTAR_RuralProsp_v2018）相关的可持续强化指标。这些数据由长期农业生态系统研究网络区域化项目产生，作为2018年3月在佐治亚州蒂夫顿举办的长期农业生态系统研究网络区域化项目研讨会的成果。
