Climate change is widely recognised as one of the major forces shaping the future. Climate impacts illustrate in stark clarity how human actions fundamentally affect the basic physical processes of the planet with vast and, in the worst cases, disastrous consequences for communities around the world. Given these profound impacts, climate change is increasingly treated as a security risk. As a changing climate is causing and will continue to cause diverse impacts across the globe, the associated security challenges are multifaceted. They involve human, community, state, and international security risks, and will require responses across all levels of decision-making, from the local to international.

The Horn of Africa faces critical security and climate risks. Persistent droughts have precipitated the onset of food insecurity and waterborne disease, while heavy rain events such as Cyclone Sagar have caused widespread flooding, mudslides, and wind damage. These challenges are increasing in severity against a backdrop of changing demographic trends—including rapid population growth, increased migration, and urbanization—and power struggles both within and between countries in the region.  

Over the years, experts have cautioned against speaking of “climate refugees.” They argue that the term “refugee,” as defined by the 1951 Refugee Convention, only applies to those who flee across borders out of fear of persecution and violence. Furthermore, evidence shows that migration is a complex phenomenon. While climate change may influence decisions to migrate to some degree, it would likely drive internal movement along well-worn migration routes, often rural-urban in nature. Ultimately, experts have argued that policymakers should think of migration as a form of adaptation to climate change, and reject the term “climate refugee.”

The world’s ocean and cryosphere have been absorbing the heat from climate change for decades, said Intergovernmental Panel on Climate Change (IPCC) Vice Chair Ko Barrett at a recent Wilson Center event on the IPCC’s Special Report on Oceans and Cryosphere. “The consequences for nature and humanity are sweeping and severe,” she said.

“In 1959, he knew it was coming,” said Delbert Pungowiyi, a Yupik native of Savoonga, Alaska, on St. Lawrence Island in the Bering Sea in an interview at the Wilson Center’s 8th Syymposium on the Impacts of an Ice-Diminishing Arctic on Naval and Maritime Operations. “He prepared me my whole life for this. It is a crisis.”

Meaningful engagement with the social and conflict implications of climate change in Solomon Islands must be firmly grounded within local worldviews—within Solomon Islanders’ physical, economic, political, and social and spiritual worlds. As we note in a recent policy brief for the Toda Peace Institute, when addressing conflict challenges exacerbated or caused by climate change, approaches should be draw upon community understandings of what constitutes peace and justice. 

International political boundaries are arbitrary creations. Today’s borders are better described as imaginary lines on maps, rather than hard barriers between states. Often using mountains, rivers, or other geographical landmarks, modern borders are entrenched in historic tradition rather than logic and fact. As a result, today’s international borders are poorly equipped to handle modern challenges, in particular climate change, which has already begun to threaten the most important state resource, fresh water.
