Influencing our Legacies

The primary objective of this final one-day team meeting of the LBA-ECO project will be to discuss and define the legacies of our project.  Clearly, we leave a legacy of hundreds of published papers, student theses, and degrees granted.  Several books and special issues and a growing archive of data will also persist.  Are these enough, and is there any more we can and should do in the final stages of this project to further define these legacies?

We are taking advantage of the American Geophysical Union Meeting of the Americas not only to facilitate travel and meeting logistics, but also to provide a forum preceding our team meeting of four days of scientific presentations that will include many results from LBA.  Several AGU sessions have been planned that include both recent developments and longer-term retrospective syntheses that are either directly LBA products or very closely related.  (see sessions) Hence, we do not intend to repeat these sessions with further plenary presentations during the brief team meeting.  Rather, we plan to use this one-day event to evaluate a series of brief summaries of major findings, accomplishments, and products of the LBA-ECO project. 

The preliminary program includes two break-out sessions, each with 3 or 4 groups meeting simultaneously, in which the groups will be asked to evaluate previously prepared straw-person statements on specific topics, such as the carbon cycle, land-water interactions, causes and effects of drought, drivers of land-use change, the adequacy of archived data, and training and education legacies.  The exact number of sessions and the topics discussed will depend, in part, on who and how many register for the meeting.  The point is not to edit statements by committee, but rather to discuss what is right and wrong, what is left out, and what needs more or less emphasis in these brief statements.  The participants will also meet in plenary, with considerable time for discussion of the results of the breakout groups’ deliberations.  If this effort is successful in drawing out a consensus on a meaningful statement of legacies, a smaller group will be recruited to edit these statements after the meeting for preparation of a journal manuscript.

An additional objective of this team meeting is to provide NASA project managers with feedback and advice on future directions of earth system science, both with respect to the Amazon and beyond.  What role should NASA play in supporting LBA-like projects or projects with broader or narrower scopes?  What lessons can be learned from what worked and did not work in LBA?  In addition to discussing the legacies of the science, each breakout group will also be asked to address these questions, and a separate plenary discussion will be held on this topic.  On-going and future activities of LBA-Phase 2 will also be presented by our Brazilian colleagues. 

We encourage all past LBA-ECO PIs to attend this final team meeting, and we also encourage participation of coPIs from the USA and South America.  Other international participation is also welcome.  This meeting will provide one last opportunity to influence what legacies will persist from NASA's contribution to LBA and what future directions are to follow.

We look forward to seeing you in Iguaçu!
