Human Insecurity from Climate Change on Vanuatu and Guam

The climate crisis is severely endangering human well-being. While the climate security nexus is omnipresent in national security strategies and on international institutions’ agendas, political responses remain insufficient and are often problematic. Among other issues, related policies often struggle with siloization or a focus on symptoms instead of root causes.

To address the core challenges to human security imposed by climate change, the “emergent practice of climate security” must be sensitive to two contexts. First, local political and economic contexts shape how these processes of environmental change translate into human insecurity. Second, climate change is only one of several ecological processes that endanger human security on our planet.

To substantiate this point, my recent publication documents the pathways to human insecurity in the specific political and economic contexts of Vanuatu and Guam. Both Pacific islands are exposed to climate change impacts such as sea level rise and intensifying extreme weather. However, their country-specific political and economic contexts translate this exposure into different forms of human insecurity. This means that similar climate change impacts have different implications for both islands.

For example, the economic differences mean that climate change impacts affect food security differently. In Vanuatu, most people engage in subsistence agriculture. In this economic context, sea level rise and tropical storms can disrupt food supplies directly by destroying local crops, particularly in rural areas. At the same time, local food habits on the Melanesian archipelago are currently shifting towards a growing reliance on lower-quality imported foods and these trends seem to be amplified by the side effects of disaster relief.

In contrast, the prevailing colonial integration of Guam into the United States economy has enforced diets centred around imported, processed food long ago. Food insecurity, therefore, comes about differently and rather results from a precarious form of economic integration. According to a study, every second respondent experienced not having enough money to pay for food and dietary quality was found to be insufficient. In particular, shares of fruit and vegetables intake are dramatically low and the mortality resulting from non-communicable diseases among Pacific islanders is on a worldwide high. In this context, climate change is rather an aggravating factor: while there is almost no local food production to be disrupted by extreme weathers, super typhoon Mawar endangered food security due to internal displacements and food price hikes. In addition, the islands tourism economy is endangered by these storms and by the additional risks that ocean warming creates for the island's coral reefs. This poses a substantial risk to local’s livelihoods.

The differences in political status between Guam and Vanuatu also affect how climate change translates into human insecurity on these islands. Since it achieved independence in 1980, Vanuatu is a sovereign nation. This enables the country to make its voice on climate change heard in international fora. But it also limits the places and modes through which its citizens can leave the archipelago. Migration is a possible climate adaptation strategy but most Vanuatu citizens’ options are limited to participation in labour mobility programs where they temporarily move to Australia or New Zealand and conduct low-paid unskilled labour. Such programs can generate knowledge transfer and support climate adaptation – but they have also been criticized for causing a ‘brain drain’ on Vanuatu and to expose labour migrants to problematic working conditions in their destination countries.

In contrast, Guam is not a sovereign nation but an organized, unincorporated territory of the United States. This provides its inhabitants with a United States citizenship and according privileges of international mobility. This political status eases mobility and created large diaspora populations within the United States mainland. However, the political dependency comes at a severe cost as Guam has no institutional voice on the stage of international climate policy and remains at the “margins and periphery of climate-change planning within the United States.”

The case of Guam also demonstrates that climate change is not the only environmental danger that human security has to grapple with. Its economic and political integration enabled the arrival of invasive species. These severely affect the island’s ecosystems. For example, the brown tree snake nearly exterminated local bird life and the coconut rhinoceros beetle harms local trees. These ecological damages affect the human security dimension of “place, self and belonging” as, for example, birds play an important role in the indigenous Chamoru culture. Environmental crime is an even more proximate result of the local economy and heavy militarization. Finally, some preliminary indications suggest “past and ongoing asbestos exposure” on Guam.

The findings of my interview-based study of human insecurity on Vanuatu and Guam allow for two takeaways. First, the study demonstrates how climate change impacts virtually every aspect of human security. For example, climate change is entangled with a wide range of issues such as food security, international labour mobility, political and economic contexts. Consequently, virtually every governmental department needs to consider the interactions between climate change and human security.

But, secondly, virtually every impact of climate change on human security is shaped by context. The comparison of Vanuatu and Guam has shown the importance of local political and economic contexts. Consequently, climate change adaptation policies need to address these structural contexts to become effective. From us non-local actors, the local intricacies of climate-related human insecurity inevitably demand a desire for open-minded understanding and a respectful cooperation with local actors such as those who seek to protect Vanuatu and Guam.
