Climate change refers to changes beyond the average atmospheric condition that are caused both by natural factors such as the orbit of earth's revolution, volcanic activities and crustal movements and by artificial factors such as the increase in the concentration of greenhouse gases and aerosol (1, 2). Climate change by global warming, which refers to the average increase in global temperature, has become a mega trend that will lead to significant global changes in the future. It is also

... pated that change in climatic conditions may lead to an increase in species migration pole wards (3). Climate change, which is largely a result of burning fossil fuels, is already affecting the earth's temperature, precipitation, and hydrologic cycles, potentially threatening recognized aspects of farming systems but also providing opportunities for improvements (4). Continued changes in the frequency and intensity of precipitation, heat waves, and other extreme events are likely, all of which will influence agricultural production. Moreover, compounded climate factors can worsen plant productivity, resulting in price increase for many important agricultural crops.
