Leveraging satellite data for greenhouse gas mitigation in Canadian poultry farming
Bibliographic record
Abstract
■ Satellite data and machine learning predict methane and CO₂ emissions in poultry farming. ■ ARIMA, LSTM, and XGBoost models reveal emission trends across 1300 Canadian poultry farms. ■ Regional and seasonal variability in emissions is driven by climate and farm practices. ■ Ontario leads methane emissions in Canadian poultry farms, driven by large-scale operations. ■ Methane emissions peak in summer, with farms emitting 67% more than processors annually. Accurate monitoring of greenhouse gas (GHG) emissions from poultry farms is essential for effective climate change mitigation. This study integrates satellite imagery with advanced machine learning techniques to analyze methane (CH₄) and carbon dioxide (CO₂) emissions from over 1,300 poultry farms and processors across Canada from 2019 to 2023. Utilizing high-resolution atmospheric data from Sentinel-5P and NASA's OCO-2 satellites, emissions were systematically mapped both temporally and spatially. We employed Autoregressive Integrated Moving Average (ARIMA), Long Short-Term Memory (LSTM), and Extreme Gradient Boosting (XGBoost) models to forecast emission trends and identify primary emission drivers. The LSTM model demonstrated superior predictive accuracy, achieving the lowest Root Mean Square Error (RMSE) values of 10 for CH₄ and 362 for CO₂. Our analysis reveals significant regional and seasonal variability in emissions, influenced by climatic conditions and operational practices. Additionally, benchmarking of emissions data was conducted to establish performance standards and monitor progress towards reduction targets. These findings provide valuable insights for policymakers and industry stakeholders, facilitating the development of targeted emission reduction strategies that align with regulatory standards and promote environmental sustainability. By combining state-of-the-art data analytics with satellite-based monitoring, this research enhances the precision and efficiency of GHG tracking in the Canadian poultry sector. Furthermore, it establishes a robust framework for formulating effective climate change mitigation strategies, thereby supporting Canada's broader environmental objectives and advancing sustainable agricultural practices.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
