This situation report released by the National Emergency Management Office (NEMO) is to inform operational partners on current situation of the secondary effects of the Hunga Tonga Hunga Ha’apai (HTHH) Volcanic eruption. This Situation report (Sitrep) covers the period stated above. Frequency of reports will depend on availability of new information and evolving operation.

Proposed Project Objective: Enhanced use of data for decision making in the environment sector throughout the Pacific region. Building on the tools and momentum the Inform project established, this scaled up project will expand the user base and fill significant gaps including in situ monitoring, increased partnerships between the environment ministries and other ministries, increase use of spatial tools, and the establishment of standardise environmental standards and key indicators for key resources.

Focusing management efforts on thermal refugia may only be effective in the short-term. Promoting adaptation to higher temperatures and facilitating migration will instead be needed to secure coral reef survival.

At present in the Fiji Islands, no guidelines are available only for biological parameters for receiving water bodies commonly used for recreational activities. The ANZECC (2000) guidelines recommend the use of Escherichia coli (E. coli) and Enterococci (Faecal Coliforms) as indicator organisms for fecal contamination of fresh and marine recreational water. This study compiled results for 3 biological parameters, namely, Total Coliforms (TC), E. coli and Faecal Coliforms (FC) at 3 sites in Fiji, namely; My Suva park, Wailea settlement and Centre Point.
