Here, we applied a multi-criteria decision-making method to investigate the rationale applied by modelers in a model ensemble study where 12 process-based different biogeochemical model types were compared across five successive calibration stages. The modelers shared a common level of agreement about the importance of the variables used to initialize their models for calibration.

Article Synopsis
- The study investigated whether enhancing forage availability for beef cattle in Brazil's Pampa biome leads to better weight gains and reduced methane emissions.
- It found that higher forage allowances (12-16% of body weight) resulted in greater daily gains and forage intake, while lower allowances (4-8%) led to poorer performance and higher emissions relative to weight gain.
- The researchers suggest using an 8% forage allowance in spring and 12% for the rest of the year to optimize cattle production and minimize environmental impact.
