Global Pasture Watch - Annual livestock headcount maps for cattle, goats, sheep and horses at 1-km 2000–2022 (FAOSTAT-adjusted)

Global annual maps of livestock distribution of cattle, goats, sheep and horses at 1-km spatial resolution convering the period of 2000–2022. The maps were produced using harmonized and used as reference data (52,883 census polygons and 678,266 individual data points), random forest predictive models using and a large stack of multi-source harmonized gridded/raster spatial layers (307 individual raster spatial layers harmonized at 1 km spatial resolution). 

Pixels values represent number of livestock animals (headcounts) calibrated according to FAOSTAT database. The adjustment was applied individually to each country, ensuring that the adjusted pixel values accurately reflected the national totals. For applications relying on headcount data from FAOSTAT the provided maps serve as a fully compatible alternative.

In line with a request from our funders, livestock maps will remain under embargo in Zenodo until the final acceptance of peer-reviewed publication. They can be accessed during the reviewing process by filling-in a form via Global Pasture Watch Early Access data program (https://survey.alchemer.com/S3/7859804/Pasture-Early-Adopters). All modeling framework presented in this work is publicly available at: https://github.com/wri/global-pasture-watch. We are currently preparing the data to be ingested in STAC and Google Earth Engine.

本数据集涵盖2000年至2022年时段，包含空间分辨率为1千米的全球年度家畜（livestock）分布地图，涉及牛、山羊、绵羊与马四类畜禽。该地图集采用经过协调统一的参考数据（包含52883个普查多边形与678266个独立数据点）、随机森林预测模型，以及共计307层经1千米分辨率协调统一的多源栅格空间图层集合制作而成。
栅格像素值代表依据联合国粮食及农业组织统计数据库（FAOSTAT）校准后的畜禽存栏数量。该校准步骤针对每个国家单独执行，确保校准后的像素值能够准确反映各国的畜禽总存栏规模。对于依赖FAOSTAT存栏数据的应用场景而言，本数据集提供的地图可作为完全兼容的替代方案。
根据资助方的要求，本数据集的家畜分布地图将在Zenodo平台处于受限访问状态，直至同行评议论文正式录用。在论文审稿阶段，研究者可通过全球牧场观测（Global Pasture Watch）早期获取数据项目的问卷表单（https://survey.alchemer.com/S3/7859804/Pasture-Early-Adopters）申请访问权限。本研究中涉及的所有建模框架已公开至：https://github.com/wri/global-pasture-watch。目前我们正在筹备将本数据集接入空间时间资产目录（SpatioTemporal Asset Catalog，简称STAC）与谷歌地球引擎（Google Earth Engine）。
