Climate Change And Its Impact On Wheat Grain Development Period And Yield In The United Kingdom From 1982-2011.

A consensus among the global scientists essentially expanded as the changes in climate developed and these sharp changes are expected to happen when the earths system is stretched across thresholds. Climate change is one of the global most imperative themes in our own time because of its consequences waiting for the upcoming generation. This paper aimed at assessing the impacts of climate change on the wheat production in the United Kingdom during the two development stages Grain filling and Grain ripening over the 30 years period from 1982-2011. A gridded meteorological data from UKCP09 was used to get the mean for the wheat development period that is most sensible to climate June to September. This was correlated with the UK wheat yield data retrieved from the department for environment food and rural affairs DEFRA using Microsoft excel and R statistical software. The results revealed a highest increase in temperature than rainfall during the wheat development period and that temperature is having more impact on wheat yield in the UK than rainfall. It is also found out that climate change is only but a factor among other factors that influenced the wheat yield in the UK for the past decades. Other factors such as genetic improvement better changes in cultivating practice better management of pests and diseases and high application of NPK fertilizers could have more effect on the UKs wheat yield for as far back as decades than only a change in climate.
