1.) Introduction
Within present century global warming will conduct to changes in weather and a climate all over the world, influencing on set of aspects of an environment. An agriculture - sector of economy which most probably will undergo to climatic changes. In this abstract, I would like to show an estimation of requirements irrigation the main grain crops under different scripts of change of a climate on an example of USA. 12 scripts of change of a climate are applied for this purpose.
As the atmosphere warms in response to increasing concentrations of atmospheric greenhouse gases, precipitation patterns will change with consequences for the supply of water for irrigation. The need for irrigation may also change. Demand may be reduced in some areas but it is equally likely that water shortage will reduce crop production in others. Where freshwater supplies become scarce and, con-comitantly, irrigation demands rise, water resource managers will face...
