Bridging Knowledge Systems: How Pacific Communities Are Reclaiming Climate Solutions Through Nature

By Sera Sefeti
NAIDIRI, FIJI, Apr 17 2026 – Climate change is no longer a distant threat. Across the Pacific, it is a daily reality reshaping coastlines, livelihoods, and the delicate balance between people and the environment. But in a region long defined by resilience, solutions are not being invented from scratch. They are being remembered, strengthened, and scaled. Nature-based solutions (NbS) approaches that use ecosystems to address climate, disaster, and development challenges have always existed in Pacific communities. For generations, villages have relied on mangroves, agroforestry, and customary practices to protect their land and sustain their people. But as climate impacts intensify, the scale and speed of change demand more.

Now, a new regional effort is working to bridge the gap between tradition and modern policy.

The Pacific Community’s Promoting Pacific Islands Nature-based Solutions (PPIN) project is designed to do exactly that: connect what communities already know with the systems that govern development and investment.

Dr Rakeshi Lata, Training and Capacity Building Officer for Nature-based Solutions at SPC, explains that the project is not about replacing traditional knowledge but elevating it.

“It functions as a bridge connecting community practices with national policies to secure resources and scale up proven local methods,” said Lata.

At its core, PPIN challenges a long-standing imbalance in development thinking where engineered, “grey” infrastructure is prioritised, and nature is treated as secondary.

“More specifically, PPIN addresses the fact that Pacific countries are highly vulnerable to climate change, disasters, and ecosystem degradation, yet development decisions still prioritise grey, engineered solutions while nature is treated as secondary or only an environmental issue,” Lata said.

This disconnect is especially stark in the Pacific, where people’s lives, cultures, and economies are deeply intertwined with the natural environment. When ecosystems fail, communities feel it immediately through food insecurity, coastal erosion, and increased disaster risks.

Yet despite the proven value of nature-based solutions, their adoption has remained limited—often fragmented, underfunded, and confined to small pilot projects.

“There is limited policy integration, technical capacity, economic evidence, and financing to make NbS ‘business as usual’ across sectors such as infrastructure, finance, agriculture, forestry, fisheries, and tourism,” Lata said.

That gap between what works locally and what is scaled nationally is where PPIN steps in.

Importantly, the project rejects the idea that traditional knowledge and modern science are in competition.

“The core philosophy of PPIN is that traditional knowledge and modern policy are not opposing forces but complementary strengths, this project aims to formalise what communities have already been practising successfully for centuries,” she said.

“PPIN actively incorporates modern science to strengthen traditional approaches.”

Across Fiji, Vanuatu, and Tonga, this integration is already visible not in theory but in practice.

Mangrove restoration, for example, is being used to reduce coastal erosion and storm surges, offering a natural alternative to costly seawalls. During Cyclone Vaiana in Fiji, boats sought shelter within mangrove systems, shielded from powerful winds and waves,  an example of ecosystem protection delivering real-time resilience.

These same mangroves also trap sediment, protecting downstream communities and coral reefs without the need for concrete infrastructure.

In rural areas, traditional agroforestry systems are being strengthened, combining trees and crops to improve soil stability, enhance food security, and build drought resilience. These systems reduce the need for engineered irrigation and land stabilisation while maintaining ecological balance.

Despite these successes, scaling such solutions has historically been difficult. Fragmented governance, siloed implementation across ministries and NGOs, and limited technical capacity have slowed progress.

PPIN is designed to dismantle these barriers.

“A central pillar of PPIN is targeted capacity-building, which includes training programmes and communities of practice by establishing peer-to-peer learning networks focusing on specific sectors to foster continued knowledge exchange and collaboration,” she said.

Beyond policy integration, the project is investing in people, particularly those closest to the land.

Training programmes, including Farmers’ Field Schools and coastal resilience initiatives, focus on practical, livelihood-based applications of NbS. Participants gain hands-on skills in climate-smart and organic farming, linking ecosystem health directly to food production and household wellbeing.

The response has been strong. Women make up more than half of participants over 80 out of 146 with youth and community practitioners also actively engaged.

As the project moves toward closure, its legacy is already taking shape not just in outcomes but also in systems that will endure.

“To ensure sustainability and long-term accessibility, materials from trainings, technical guidance, needs assessment findings and more are being consolidated and hosted within a regional NbS knowledge hub led by SPREP,” Lata said.

“This hub provides a single, trusted platform where governments, practitioners, communities, women and youth can access the PPIN resources.”

But perhaps its most lasting impact will be less tangible and more powerful.

“Beyond materials, PPIN leaves behind strengthened regional networks and communities of practice, which will continue to connect practitioners across countries and sectors.”

In a region on the frontline of climate change, the future may not lie in choosing between tradition and science but in weaving them together.

Because in the Pacific, resilience has never been built on one system alone. It is carried across generations, across knowledge systems, and now, increasingly, across policy and practice.
