收藏资源简介:
cafo-iowa是一个关于爱荷华州集中动物饲养操作(CAFOs)的数据集,通过结合NAIP卫星图像、手动标注、爱荷华州DNR许可记录和ReGrid地块数据编译而成。它包含6,525个爱荷华州的断奶到育肥和生长到育肥养猪设施,这些设施通过卫星检测到的谷仓进行匹配。每个设施都包括报告的动物单位数量(来自州许可记录)和基于手动标注谷仓足迹面积估计的动物单位数量,从而支持分析《清洁水法》许可规则下的低报行为。数据集使用NAIP 2021航空影像、爱荷华州DNR主矩阵许可数据和ReGrid地块数据编译。许可地址和地块所有者信息已被隐去;但可根据研究请求分享未隐去版本。该数据集旨在研究《清洁水法》下的阈值博弈,即操作者可能低报动物数量以避免联邦许可要求。
The cafo-iowa dataset is a curated dataset focused on concentrated animal feeding operations (CAFOs) in Iowa, compiled using 2021 National Agricultural Imagery Program (NAIP) aerial imagery, manual annotations, Iowa Department of Natural Resources (Iowa DNR) master matrix permit records, and ReGrid parcel data. It encompasses 6,525 wean-to-finish and grow-finish swine facilities in Iowa, which were identified by matching barns detected via satellite imagery. Each facility includes both the reported animal unit (AU) count sourced from state permit records and the AU count estimated based on the area of manually annotated barn footprints, enabling analysis of underreporting behaviors under the Clean Water Act (CWA) permit regulations. Permit addresses and parcel owner information have been redacted; the unredacted version of the dataset may be shared upon submission of a research request. This dataset is designed to support research on threshold gaming under the CWA, where facility operators may underreport animal counts to evade federal permit requirements.
