Global climate change and its impact on world cereal productivity and area of land under cultivation

The over ambitious approach of mankind towards development has invited so many environmental problems. Rising temperature is one of them. It is expected that the rising temperature will have a dent over the cereal productivity despite the fact that a lot of improvement have been realized in farm mechanization. It was also expected that rising temperature will affect the soil fertility and may reduce/stop the process of bringing new land under the farm cultivation. To analyze these relationships simple statistical tools like correlation and regression are used. The statistical results are against the expectation. We have a positive regression coefficient between cereal productivity and temperature showing that with the rise in temperature cereal productivity has increased. The correlation value between temperature and capital states that the negative impact of temperature is eliminated by improving the process of adoptability since increase in temperature is accompanied by rise in the use of capital. At the same time the positive correlation value between temperature and land shows that temperature has not made any negative impact on soil quality and thus cereal productivity.
