How changing climate can affect wheat productivity

Abstract

The effects of climate change varied on wheat in temperate and tropical regions. These regions differ significantly in their biophysical characteristics of climate and soil, and in the vulnerability of their agricultural systems and people to climate change. At the basis of understanding of climate impact on wheat, the rates of most biophysical processes are highly dependent on climate variables such as radiation, temperature, and moisture that vary regionally. For example, rates of plant photosynthesis depend on the amount of photosynthetically active radiation and levels of atmospheric carbon dioxide (CO₂). Temperature is an important determinant of the rate at which a plant progresses through various phenological stages towards maturity. The accumulation of biomass is constrained by the availability of moisture and nutrients to a growing plant. Since crop phenology is one of the most important plant process in determining final yield and allowing adaptation of crops to climate change with the effect of warming climate.
