2011 was another rich and active year for WIOMSA! The Association successfully continued to be the hub of activities in the WIO region. WIOMSA organized two major events in the year: the Regional Conference on “Climate Change Impacts, Adaptation and Mitigation in the WIO region: Solutions to the Crisis” held in Mauritius in March 2011 and the Seventh WIOMSA Scientific Symposium, which took place in Mombasa, Kenya in October 2011. These events were well attended, together, attracting about 700 participants. This Report covers WIOMSA’s activities for the year 2011. One of the major highlights for this period is the completion of twelve projects. This is the highest number of projects to be completed in a single year since the start of the competitive research grant scheme in 2000, a remarkable achievement indeed!
