24.6 Conclusion
Free-air CO2 enrichment studies have been a valuable tool for the investigation of plant and ecosystem responses to rising CO2 levels. The challenges for the next phase of FACE research are clear.
-
Multidisciplinary teams of investigators must take advantage of emerging technologies to significantly increase our mechanistic understanding of the responses that FACE experiments have confirmed will take place during the next century.
-
If we seek the ability to predict and understand how our managed, and natural, ecosystems will respond to the predicted multiple and concurrent changes in our environment, more interactions with other global change factors must be included in future experiments. To meet these challenges, future FACE experiments will need to be larger to accommodate multiple environmental changes.
