The global climate crisis could see more than a billion people displaced from their homes in the next 30 years, as ecological disasters drive mass migrations and greater armed conflict, according to a new report released Wednesday.The Ecological Threat Register, conducted by the Sydney-based Institute for Economics and Peace (IEP), projected that as many as 1.2 billion people around the world could be displaced by 2050. No country will be able to escape the impact of the climate crisis — but the world’s poorest and most vulnerable populations will be hardest hit.
“Ecological threats and climate change pose serious challenges to global development and peacefulness,” the report said. “The world’s least resilient countries, when faced with ecological breakdowns, are more likely to experience civil unrest, political instability, social fragmentation and economic collapse.”The report drew on data from international organizations like the United Nations, the Internal Displacement Monitoring Centre, the Food and Agriculture Organization, and the IEP’s prior research on countries’ resilience levels. Using these figures, the IEP then calculated the relative threats of population growth, water stress, food insecurity, droughts, floods, cyclones, and rising temperature and sea levels.It found that more than a billion people lived in 31 countries that had low resilience — meaning they aren’t equipped to withstand the impact of ecological change in the coming decades.The regions facing the highest number of threats are Sub-Saharan Africa, South Asia, the Middle East and North Africa, the report said.”Not all of these people will be displaced, however it is likely that a large number of them will be,” said the IEP.
Better-resourced countries in places like North America and Europe will be more able to manage the effects of these disasters — but they’ll likely face huge flows of climate refugees, the report warned.”This will have huge social and political impacts, not just in the developing world, but also in the developed, as mass displacement will lead to larger refugee flows to the most developed countries,” said IEP founder Steve Killelea in a news release, adding that ecological change was “the next big global threat to our planet.”

The global population currently stands at 7.8 billion. That number is expected to reach 10 billion by 2050 — straining the world’s already stretched natural resources, the report said, citing data from the UN’s Department of Economic and Social Affairs.Most of this population growth is expected to take place in countries with ongoing armed conflict, like those in Sub-Saharan Africa, the report said.Citing research from the global non-profit organization World Resource Institute,the report projected that by 2050, global demand for food will increase by 50% and 3.5 billion people could suffer from food insecurity.Water scarcity may be an even bigger issue — already, there are more than 2.6 billion people facing high or extreme water stress, meaning they either don’t have enough water for their needs or that their water supply is at risk of disruption, the report said.
