After 2050, the risk of more severe yield impacts increases, as boom-and-bust cycles affect many regions.
Water quality and crop yield impacts due to management factors such as cropping system, tillage, and drainage design were investigated.
After 2050, the risk of more severe yield impacts increases and depends on the level of warming.
The yield impact can be positive in many environments, but negative in terminal drought environments.
Moreover, practically the entire distributions of potential yield impacts were negative suggesting CA is highly unlikely to generate yield benefits for farmers in the two locations.
Improving crop models' response to high temperature impacts on cereal yields will require experimental data representative of field production and should be designed to connect what is already known about physiological responses and observed yield impacts.
This work provided a quantitative review of the water quality and crop yield impacts of artificially drained agronomic systems across North America by compiling data from drainage nutrient studies in the "Measured Annual Nutrient loads from AGricultural Environments" (MANAGE) database.
Conservative estimation of yield impact forecasts effect step changes at maximal technology adoption in 2016, 2020, and 2024, with no phase-in period.
Methodology: As was the case with the mid-term evaluation, this study did not yield impact estimates or quantify the expected change over time due to the cash transfer.
According to Kato et al. (1999), fire exclusion is likely to be more advantageous with longer cropping phases, however, we found a greater positive yield impact, given as the percentage yield change, on the 3-month maize than the 3-year plantain.
