The Crop Systems and Global Change Lab (CSGCL), applies systems theory to the solution of complex agricultural problems and to the development of computer-aided farm decision support systems and assessment tools for environmental study and analysis. This Lab undertakes research to analyze and design systems, to develop models and expert systems, and to generate and evaluate data bases. It carries out research to improve the growth, yield and quality of crops in the face of climatic changes, through increased understanding of mechanisms controlling response and adaptation to CO2, light, water, temperature, and soil chemistry. Studies are undertaken at molecular, biochemical, organismic, and community levels in controlled environments, greenhouses and in the field, exploiting natural and induced genetic variability and emphasizing interactions among environmental variables. CSGCL carries out basic and applied research to improve methods of managing agriculturally important crops.
