Agricultural production is highly dependent on weather and climate. Without adequate rainfall and appropriate temperatures, crops fail and pastures become barren. Interestingly, the opposite is also true: weather and climate are influenced by agricultural practices. By managing croplands and pastures farmers influence a series of physical, chemical and biological interactions between the Earth's surface and the atmosphere that can affect air temperature and precipitation in many ways.
In is important to understand that there is still a lot of uncertainty on the impact of climate change to agriculture. These potential impacts are not clear and depend very heavily on assumptions that are developed from the use of models to make projections.
Also, the effectiveness of future adaptations will be a key factor.
That means there may be some surprises along the way.
