Climatic changes and environmental variation are expected to exacerbate the problems of food security in the future by force on agriculture. “Climate change may have more effect on small and marginal farmers, particularly who are mainly dependent on vegetables (Anonymous 2009)”. However, There are still several issues about the impact assessment, adaptation and mitigation of climate change in agriculture Climate change by global warming, which leads to rising temperatures in the world, has become a megatrend that will lead to major climatic changes in the future. In its Fourth Climate Change Report (2007), the United Nations Intergovernmental Panel on Climate Change (IPCC) presented considerable scien- tifc evidence and they have become clearly recognized throughout the world.
