Other Publications Resulting From Research And Extension
From my research work and extension activities, I have presented results and advances in oral and poster presentations in over 40 Symposia and Scientific Meetings held between 1997 and 2003. As a result I have produced also more than 40 summaries and over 30 formal institutional reports, as well as several pamphlets to technicians and farmers. Other 9 reports were elaborated while working as a Scientific Consultant for Forest Management Certification of 9 communitarian forest operations (under the FSC certification policy).
