The Canadian beef sector accounts for 8% of total GHG emissions at the national level. Beef cattle producers in Western Canada manage a significant portion of the agriculture land base and cattle herd. Volatility in commodity pricing, continuing trade issues and a changing climate require proactive decisions if this sector is to be sustainable. Knowledge gaps on productivity and environmental sustainability of low-cost management practices are factors limiting good management decisions and sound policy.

A whole-system approach is needed to better assess current and alternative management practices in western Canada. In large part, the challenge is related to choices made by producers with respect to land management, where a given change can have upstream and downstream consequences that are not easy to predict. For example, a decision to convert grassland to annual crops to support an expanding bioenergy market can change feeding strategies for the cattle herd, with increased emphasis on byproduct use (e.g. canola meal), and thus impact methane emissions. Hence, BMPs need to be assessed on a full life-cycle basis.

This project aims to provide science-based knowledge, technologies and strategies in order to place Canada’s farmers in a better position to mitigate GHG through reductions of emissions and/or an increase in carbon sequestration, consistent with the overall mission of the Global Research Alliance. The specific objectives of the project will be to: 1) provide further scientific information and knowledge to support existing concepts of BMPs and to propose new BMPs to reduce GHG emissions; 2) implement this knowledge and place the net GHG impacts of BMPs into the context of a life cycle assessment; 3) transfer knowledge through active collaborations with federal and provincial extension personnel; and 4) follow-up on BMPs interactions that have been adapted by producers to mitigate GHG emissions.

Research activities and outputs:

Research Activities:

a) Develop suite of BMPs to model

b) Create LCA model from cradle-to-farm gate and estimate environmental impacts associated with beef production systems in Western Canada

c) Utilize data from scientific studies at University of Manitoba to populate models. Data will include up-to-date information on : over-wintering practices in non-confinement cattle; better estimates of enteric methane emissions and nitrogen dynamics for nitrous oxide emissions; better understanding of long-term effects of crop rotations on GHG emissions; land use change (perennial vs. annual) effects on GHG emissions.
