Pacific communities embrace Litter Intelligence

Back in 2021, in a move that rang true with the team at Sustainable Coastlines, organisers of World Ocean Day decided to drop the ‘S’ from ‘oceans’. The reason? What we have categorised as distinct bodies of water is in reality a single ocean. This means that our actions to protect it are taken as part of a global community, acknowledging a shared climate and a shared future.

With the celebration coming around soon, on 8 June, we’re again reflecting on this, and what it means for us as a local charity working on the global problem of litter and plastic pollution. Tackling it here in Aotearoa New Zealand has implications beyond our shores. It’s true that if we clean up our act at home there will be less plastic flowing to the global ‘pool’ of ocean plastic. But more than that, homegrown solutions have the potential to build on positive change overseas, and we are privileged to have been invited to share the Litter Intelligence programme with communities in the Pacific.

For the last couple of years, we’ve collaborated with the South Pacific Regional Environment Programme, also known as SPREP, delivering online Litter Intelligence training to enable communities to run litter surveys in Fiji, Wallis and Futuna, Samoa, Vanuatu, and Tonga. Based on the success of the initial pilot, the French Development Agency has provided funding to deliver in-person workshops, which will enable community groups, as well as local and central government staff, to run Litter Intelligence surveys and audits.

“The Litter Intelligence programme has great international standing and is seen as a best-practice tool for community engagement in litter monitoring and waste reduction action. We feel honoured to be invited to deliver training to community groups and government agencies across the Pacific,” says Sustainable Coastlines CEO Josh Borthwick.

Waste, plastic pollution in particular, poses a significant threat to Pacific Island nations, impacting food security, livelihoods, and the health of ecosystems themselves. Setoa Apo, the principal waste management officer of Samoa’s Environment Ministry, notes the role that litter data has to play in solving these problems.

“Plastic pollution — marine pollution — is a fast-emerging environmental issue right now. That’s why we are trying to collect whatever is on the coast here at Vaiusu so that we can audit it, and then give the information to the community and share it with the regions,” says Apo.

So far, Sustainable Coastlines staff have had the privilege of running workshops in the Solomon Islands and Fiji, and have plans to do the same in Vanuatu, Samoa, and Tonga in June and July this year.

While the litter data returned from some of the initial surveys in the Solomons and Fiji show a high litter density, Sustainable Coastlines’ data and insights analyst, Carla Fonseca-Paris notes that we can’t draw conclusions about the nature of the litter problem there until we have a number of repeat surveys and a wider distribution of sites.

“We don’t know how long it took for the litter from the first survey to accumulate there. In three months, when the community undertakes another survey, we’ll have information around what’s accumulated at the beach in that period. Subsequent surveys will provide more data, allowing us to analyse litter accumulation rates, which will help paint a picture of the litter problem.”

Caitlyn Prince, one of Sustainable Coastlines’ engagement facilitators, helped to coordinate the workshops in Fiji. She was struck by the contrast between Fiji’s beautiful environment and the litter present.

“The amount of plastic pollution finding its way to the coastline of Viti Levu [Fiji’s main island] and surrounding islands is an issue that needs action,” says Caitlyn.

“I expect it’s a similar story all across the globe, so it’s really encouraging to work alongside people who are working towards solutions.”

On our visits to both the Solomon Islands and Fiji, the Sustainable Coastlines team observed that much of the litter looked to be related to drinks packaging, and the first surveys appear to back this up. In Fiji, the results from two surveys show that aluminium cans made up 4.5% of the total litter collected, with bottles under two litres making up 1.9%. Drinks packaging also looks to be a large contributor to the litter present in the Solomon Islands survey sites. The seven surveys completed showed that aluminium cans made up 12% of all litter collected, and bottles under two litres, 23%.

As mentioned, more data is needed for a full understanding of the litter affecting these coastlines and where it’s coming from. But once communities have a statistically significant number of surveys under their belts, data like this could potentially point policymakers to focus on things like safe and accessible drinking water, for both human health and the health of the environment, alongside other infrastructure measures they might consider to tackle the waste problems.

Marine litter is a complex, global problem. While some litter is mismanaged waste that leaks to the ocean, ocean currents also convey litter to coastlines, with different accumulations depending purely on where the coastline is situated.

Overall, the workshops undertaken so far in the Pacific are a cause for optimism about the future of waste and community-led action in the Pacific. Ben Knight, our community engagement director, ran some of the Solomons workshops and noted that there were already plenty of local groups formed to combat litter and plastic pollution, such as Plasticwise Gizo.

“There was also a lot of support for the idea of measuring the problem in order to influence decision-making around solutions,” noted Ben. “This is the idea behind Litter Intelligence, so it’s great to be able to support these communities with training and a platform with which to do this.”

Similarly, Caitlyn was inspired by the strength and motivation she encountered in local groups in Fiji, particularly Suzanne from the Pacific Ocean Litter Youth Project and Andrew Paris from Blue Prosperity Fiji. “I came away with gratitude and motivation to be as dedicated and compassionate as they are in the fight against plastic pollution.”

Caitlyn’s main takeaway from her experience in Fiji is a great reminder for all of us who love the ocean and want to protect it.

“All of our small actions are a part of a global movement to halt plastic consumption and pollution. There are so many people showing up to positively influence our future, and meeting some of them affirmed for me why it’s so important to keep doing whatever we can to add to this global movement.”
