For a long time it has been believed that the effects of global warming on agriculture and food supply is going to be a positive one. This is because the rising level of carbon-dioxide resulted for global warming will help the greeneries for photosynthesis. Thus there will be a rise of agricultural production and food supply. The theorem received a boost after the evidence of a sharp rise of barley production as one of the effects of global warming in Iceland which was quite impossible even few years ago. But more recent experiments and researches have revealed that the effects of global warming on agriculture and food supply are not that good after all. AN UNEP 2001 report on the global warming has predicted that USA is going to have more droughts, floods, landslides and storms.
Winter will gradually be shortened and sobered down, while summer will rise in expansion and severity. Along with this heavy rain, big storm, heavy snowfall, high sea level, increasing coastal erosion and other problems will occur. As another example of the effects of global warming on agriculture and food supply - with the rise of temperature by 3 to 11 degrees in this century, the production rate of the main crops – the rice, corn, wheat, barley, soybeans and sorghum – will be cut down by 3-5% for each point rise of temperature for global warming. However with all these effects of global warming on agriculture and food supply, new attempts have been made to adjust the agricultural and food production method according to the changing atmosphere.
So to fight the effects of global warming, the researchers have established new methods of production with continuous revision of models. But still the best possible process to reduce the effects of global warming on agriculture and food supply is to be established.
