Data for: Spillover effects of organic agriculture on pesticide use on nearby fields

The environmental impacts of organic agriculture are only partially understood and whether such practices have spillover effects on pests or pest control activity on nearby fields remains unknown. Using roughly 13,000 field observations per year from 2013-2019 in Kern County, CA , we estimate that organic crop producers benefit from surrounding organic fields, decreasing overall pesticide use and pesticides targeting insect pests. Conventional fields, in contrast, tend to increase pesticide use as the area of surrounding organic production increases., Please see accompanying manuscript for details on data creation., , # Analysis data for: \"Spillover effects of organic agriculture on pesticide use on surrounding fields\" [https://doi.org/10.5061/dryad.vhhmgqp1f](https://doi.org/10.5061/dryad.vhhmgqp1f) These datasets include information on cropland and pesticide use from Kern County, CA and US wide. For Kern County, information on cropland includes characteristics of the focal crop field (e.g. crop type, field size, organic status) as well as information about the landscape surrounding each focal crop field. For the national-scale analysis, information on pesticide use and crop characteristics are provided at the county level. ## Description of the data and file structure There are 6 data files: 1.    SpatialOrganic_MainText_R2.csv: This file includes the data required to reproduce figures 2-3 in the main text. \"\" indicates missing data. 2.    SpatialOrganic_SI_R2.csv: This file includes the data required to reproduce analyses in the supplementary information, except SI figure 6 (removing overl...当前学界对有机农业（organic agriculture）的环境影响仅具备局部认知，且此类种植模式是否会对周边农田的害虫种群或害虫防控工作产生溢出效应，目前仍无定论。本研究利用2013至2019年美国加利福尼亚州（California）克恩县（Kern County）每年约13000次田间观测数据，评估发现有机作物种植者可从周边有机农田中获得正向溢出收益，整体农药施用总量及针对昆虫害虫的专用农药施用量均显著降低。与之形成对比的是，随着周边有机种植面积的扩大，常规农田的农药施用量通常会随之上升。有关数据构建的详细细节，请参阅随附的研究手稿。 # 论文《有机农业对周边农田农药使用的溢出效应》配套分析数据集 https://doi.org/10.5061/dryad.vhhmgqp1f 本数据集涵盖来自美国加利福尼亚州克恩县及全美范围的农田与农药使用信息。其中克恩县数据包含目标农田的特征信息（如作物类型、田块面积、有机种植属性），以及各目标农田周边的景观格局信息。针对全国尺度的分析，数据以县为单位提供了农药使用量与作物特征相关信息。 ## 数据与文件结构说明 本数据集共包含6个数据文件： 1. SpatialOrganic_MainText_R2.csv：该文件包含复现正文图2至图3所需的全部数据，缺失值以""表示。 2. SpatialOrganic_SI_R2.csv：该文件包含复现补充材料中所有分析所需的数据（补充图6除外，移除重叠...）
