The researchers have used evidence from Mato Grosso, Brazil, to show that changes in agricultural output stemming from the sensitivity of cropland area and cropping frequency to interannual climate variability are of similar magnitude to agricultural output changes associated with the sensitivity of crop yield to interannual climate variability.
Area and frequency e¤ffects may either exacerbate or off¤set production losses through yield eff¤ects. Therefore, it may be inaccurate to use yield sensitivity to climate variability as a proxy for crop production sensitivity to climate variability.
