SYDNEY, Oct 14 (IPS) - The Pacific Islands region is both the frontline of the wrath that climate change is lashing on the environment and human life and the drive for innovation and solutions to stem the destruction and strengthen island environments for the future. The survival of life, even nations, in the Pacific depends on it.

"The world has much to learn from you... Plastic pollution is choking sea life. Greenhouse gases are causing ocean heating, acidification and rising seas. But Pacific Islands are showing the way to protect our climate, our planet and our ocean," United Nations Secretary-General António Guterres, said during his visit to Tonga in August.

And the Pacific Community's PROTÉGÉ Project (the name means ‘protect' in French) is doing just that. Launched six years ago with funding by the European Development Fund (EDF), it is striving to advance climate resilient development through protecting and better managing biodiversity and natural renewable resources, such as freshwater, in the three French overseas territories of New Caledonia, French Polynesia and Wallis and Futuna, as well as the British overseas territory of Pitcairn, in the Pacific. To achieve this, it has brought together provincial and local-level governments, consulting firms, non-government organizations, and local communities and is led and coordinated by science and development experts from the regional development organization, Pacific Community (SPC), that works for 22 Pacific island governments and territories.

It honors the interconnected nature of island ecosystems through the four focus areas of the project: agriculture and forestry, coastal fisheries and aquaculture, invasive species and water. For instance, "in an integrated watershed management approach, what happens in the mountains ends up in the rivers and eventually in the sea," Peggy Roudaut, SPC's PROTÉGÉ Project Manager in Noumea, New Caledonia, told IPS.

"The water theme is central," she continued. "By working on the sustainability of water resources and supporting the water policies of the territories, while also promoting actions to make aquaculture and agriculture more sustainable, we contribute to making the overseas countries and territories more resilient to the effects of climate change."

While the Pacific Islands are surrounded by a vast 161.76 million square kilometers of ocean, their sources of freshwater are fragile. Most islanders who live in rural areas have to choose from limited groundwater lenses, streams or rainwater harvesting. Ninety-two percent of Pacific islanders living in urban centers have access to clean drinking water, declining to 44 percent in rural communities, reports the Pacific Community (SPC).

Improving water security is a priority in the national development goals of Pacific Island countries, but real progress is being undermined by population growth, which is rapidly increasing demand, and the worsening impacts of climate change. Rising air and sea temperatures, more heatwaves and unreliable rainfall with rising sea levels that are driving coastal erosion are all taking their toll on the region, reports the Intergovernmental Panel on Climate Change (IPCC).

In the western Pacific, temperatures are predicted to increase by 2-4.5 degrees Celsius by 2100, while most Pacific Island states will witness a sea level rise 10-30 percent higher than the global mean, which is projected to be 38 centimeters by the end of the century, according to the United Nations.

And then there's pollution. "For many rural and remote and even urban communities, water sources that were once safe to drink or use for farming have become unsafe due to pollutants, including improper waste disposal and agricultural runoff," Professor Dan Orcherton, Professor in Sciences at the University of Fiji, told IPS, emphasizing "that freshwater security in the Pacific Islands is quite precarious, reflecting a complex interplay of natural and human induced factors."

The Pacific Community (SPC) is working to protect, manage and support countries to monitor freshwater reserves across the entire Pacific region. PROTÉGÉ, specifically focused on Pacific territories, has been supporting this work by regenerating forests and vegetation in their vicinity and developing long-term climate-resilient management plans.

The quality of drinking water is also being improved through closely studying detrimental factors, such as construction and development, and decontaminating rivers and wells that are polluted by waste and landfills.

Healthy forests are the lungs of flourishing natural ecosystems and biodiversity that, in turn, regulate the local climate, protect natural watersheds and prevent soil erosion. Forests cover 43.7 percent of the five archipelagos in French Polynesia, which is regularly battered by cyclones, droughts and sea level rise. Meanwhile, in Wallis and Futuna, a small group of volcanic islands in the central Pacific with scarce freshwater, deforestation due to forest clearing, and soil erosion are serious problems.

Closer to the east coast of Australia, forest covers 45.9 percent of the islands of New Caledonia. Here, water resources are being affected by nickel mining, forest fires and soil erosion. Scientists forecast that, against predicted climate change impacts, 87-96 percent of native tree species in New Caledonia could decline by 2070.

Roudaut spoke of three projects in New Caledonia that, together, boosted the reforestation of 27 hectares, the replanting of vegetation around drinking water supply catchments and put in place 3,460 meters of fencing around water sources that will prevent damage, whether by fires or wildlife, such as deer and wild boars. Local communities were vital to their success, with 190 islanders, many of whom were women and youths, involved in making the projects a reality on the ground.

The World Wildlife Fund (WWF) is a partner in one being rolled out in the district of Dumbea, north of the capital, Noumea. The project focuses on the Montagne des Sources upstream of the Dumbea dam, which provides water to 110,000 people, or 40 percent of New Caledonia's population.

Solène Verda, Head of WWF's Forestry Program in the territory, told IPS that the incidence of forest fires, as well as floods and droughts, which also affect water security, will only intensify with climate change. "Every year in New Caledonia, fires destroy around 20,000 hectares of vegetation, which is a disaster regarding the islands' surface; in ten years, 10 percent of the main island has already burned," she said. "The predictions are not cheery for New Caledonian forests and, thus, the freshwater resources."

The PROTÉGÉ initiative is tackling one of the greatest inhibitors to combating climate damage, which is limited technical and management capacity. Due to "the remoteness of these islands and small populations... combined with the emigration of skilled professionals out of the region, there is minimal capacity within regional countries to respond to the day-to-day vulnerability threats, let alone the frequent natural disasters experienced," reports the United Nations Environment Program (UNEP).

"Thanks to SPC's PROTÉGÉ, we had the opportunity to test different forest restoration techniques on our degraded watersheds... and it has given us a clearer idea of the methods best suited to our context," Verda said.

It is a key issue understood by the EU, which has supported the initiative with 36 million euros, in addition to 128,000 euros contributed by the three French territories.

PROTÉGÉ is part of our "commitment to environmental sustainability, climate resilience and sustainable economic autonomy for these small, often vulnerable island territories in line with the Green Deal," Georges Dehoux, Deputy Head of the Office of the European Union (EU) in the Pacific in Noumea, told IPS. The Green Deal is the EU's ambition to achieve net zero emissions and non-resource equitable economic growth to become the world's first climate-neutral continent by 2050.

All Pacific Island countries and territories "are facing the same environmental and economic challenges, and a combined and coordinated response at the regional level will ensure better resilience to these challenges," Dehoux added.

Those working with the project have a sense of urgency about what they are aiming to achieve. For, as the International Monetary Fund (IMF) advises, "We can still reverse some of the damage we have inflicted on our precious planet. But time is running out. If we don't take decisive action in the next 10-20 years, the damage will have passed irreversible tipping points."
