Artistic research[ edit ] The controversial trend of artistic teaching becoming more academics-oriented is leading to artistic research being accepted as the primary mode of enquiry in art as in the case of other disciplines.
View abstract View article PDF The potential impacts of climate change on crop productivity are of widespread interest to those concerned with addressing climate change and improving global food security.
Two common approaches to assess these impacts are process-based simulation models, which attempt to represent key dynamic processes affecting crop yields, and statistical models, which estimate functional relationships between historical observations of weather and yields. Examples of both approaches are increasingly found in the scientific literature, although often published in different disciplinary journals.
Here we compare published sensitivities to changes in temperature, precipitation, carbon dioxide CO 2and ozone from each approach for the subset of crops, locations, and climate scenarios for which both have been applied.
For precipitation, there are many reasons why estimates could be expected to differ, but few estimates exist to develop robust comparisons, and precipitation changes are rarely the dominant factor for predicting impacts given the prominent role of temperature, CO 2, and ozone changes.
A common difference between process-based and statistical studies is that the former tend to include the effects of CO 2 increases that accompany warming, whereas statistical models typically do not. At the same time, those who fund or use crop model projections should understand that in the short-term, both approaches when done well are likely to provide similar estimates of warming impacts, with statistical models generally requiring fewer resources to produce robust estimates, especially when applied to crops beyond the major grains.Welcome to Dream Essays.
