I thought I’d be tweeting and blogging away from the field – but alas, since Digicel installed a tower in Kubulau, Vodafone signal is but a figment of my imagination. So I am cut off from all forms of communication with the outside world – six days in, it feels like a weight has been lifted.
After 18 long months of slogging it in the office and pitching proposals non-stop to donors, we are finally back in the field for a new project. During the past few years we have been collecting information about the reefs to provide recommendations about where to set up no-fishing zones (or marine protected areas – MPAs) and monitoring their effectiveness over time. This trip is different – we have asked the village of Kiobo in Kubulau District to open their MPA to see what happens. “What!” the purists would yell, “Open an MPA? Are you crazy?” But the simple fact is that rural communities in Fiji routinely open their MPAs to provide food for social functions. This practice comes from a cultural legacy throughout Melanesia of creating short-term, no-fishing zones specifically so that they would be able to have a great harvest for a social event and redistribute the food as a show of wealth and status. Thus, even though most communities within the Fiji Locally Managed Marine Area network say that they want to have fish for the future, they also very much want to have fish for the present.
More and more frequently, there are expectations that the MPAs can provide a source of income whenever the community needs money to pay school fees, church fees, provincial levies, etc. This is leading to more intense and more frequent harvests from MPAs, and the fish just don’t stand a chance. Here is where we come in – our current project is evaluating how much you can extract from an MPA and still have sustainable fisheries for the future. We recognise that the MPAs in Fiji work best where cultural practice is strong – and if cultural practice demands occasionally opening an MPA, then we need to be able to offer some better guidelines about how much can be harvested besides just “don’t take all the biggest fish.”
In the field with us this time is Jordan Goetze, a PhD student from University of Western Australia, whom I’ve recruited to look at the ecological impacts of harvesting MPAs for his doctoral research. On this trip, he is testing out a range of survey methods to see which ones best document the impact of a week-long harvest from the Kiobo MPA. Our WCS staff are collecting our standard underwater visual census data, which he will compare with before and after harvest surveys of the reefs using diver-operated video and baited remote underwater video surveys (BRUVs). The diver-operated video information is certainly more efficient to collect than our laborious fish and benthic counts, while the BRUVs potentially allow us to collect a better record of predatory fish that are often skiddish of SCUBA divers. At the same time, we have sent out WCS staff and a Masters student from the University of the South Pacific to conduct household interviews to find out what the local people are expecting from the harvest in terms of food and monetary benefits, and then we will resurvey them after the event to see how these expectations were met.
Conducting fieldwork in remote Fiji is always challenging. Today we are stuck in the village as the fuel hose for our dive compressor became shredded, thus preventing us from filling our dive tanks. Waisea and Akuila have gone to Savusavu in search of a replacement. The winds have been up, causing rather treacherous conditions mooring at sites. Under pressure to complete 4 dives a day, we often find ourselves returning to the village for a low tide swap of empty for full tanks, which must be lugged across hundreds of meters of intertidal seagrass and algal beds. And there is no rest for the weary in the evening – data must be entered, kava drunk, and special efforts made to conduct awareness presentations in the surrounding villages so they understand what they stand to gain from the information collected from these surveys. Full support of the local communities is crucial for this project to succeed, so it is worth the extra effort to haul our generator, projector and white sheet around to the various villages by boat, often in the dark, for evening presentations to ensure that everyone knows what is happening.
What will we find when the MPA is opened? Unfortunately, it looks as though the local reports of emboldened poachers encroaching on inshore fishing grounds may be true. We certainly did not see overly abundant fish life in the MPA, and invertebrates were few and far between. Yet, hopefully the men and women of Kiobo village will still be able to pull in a sizeable catch, which can provide them a modicum of income while allowing us to gather a piece of the puzzle to evaluate thresholds of impact. Keep your coconut wireless tuned for the results . . . moce mada. Stacy
