This report addresses the direct effects of increased CO/sub 2/ concentration on plant processes, and the indirect effects of climate changes caused by increased CO/sub 2/ concentrations. It limits indirect climatic change or effects on plants to temperature and rainfall. Growth of a crop involves several physiological processes, e.g., photosynthesis, respiration and transpiration. The integral of these and other processes over a season results in yield - grain, tubers, etc. Both positive and negative responses of these processes to climatic changes occur. Some of these individual responses are known; many others are not. Because of the complex nature of the interdependence and feedback of the total physiological system, quantitative prediction of the net response to a climatic change, especially in genotypes yet to be developed, is impossible. Therefore a systems simulation analysis is necessary. Research needs, to evaluate the effects of increased CO/sub 2/ on agricultural productivity, include the need for controlled environment experiments to measure crop responses to climate, done in such a way that the resulting data are useful in system studies.
