At least 100 million people have been forced to flee their homes due to violence, persecution, or other forms of public disorder over the last decade, according to UNHCR, the United Nations refugee agency. That's about one in every 97 people on the planet, roughly one percent of humanity. If such war victims had been given their own state to homestead, it would be the 14th largest nation, population-wise, in the world. According to UNHCR, fewer war refugees and IDPs are able to rebuild their lives. In the 1990s, an average of 1.5 million refugees were able to return home annually. For the last 10 years, that number has dropped to around 385,000. Today, about 77% of the world's refugees are trapped in long-term displacement situations thanks to forever wars like the conflict in Afghanistan that is now in its sixth decade.
Yet, these numbers, they're set to be dwarfed by people displaced by another signature story of our time: climate change. So much worse is yet to come, according to experts.
A recent forecast suggests that, by the year 2050, the number of people driven from their homes by ecological catastrophes could be 900% greater than the 100 million forced to flee conflicts over the last decade.
Predictions now warn of increasing ecological disasters and resource wars supercharging the already surging phenomenon of global displacement. According to a recent report by the Institute for Economics and Peace, a think tank that produces annual global terrorism and peace indexes, two billion people already face uncertain access to sufficient food -- a number set to jump to 3.5 billion by 2050. Another one billion "live in countries that do not have the current resilience to deal with the ecological changes they are expected to face in the future." The report warns that the global climate crisis may displace as many as 1.2 billion people by 2050.
In 2010, Bassiaka Dao, the president of the confederation of farmers in Burkina Faso, told the United Nations news agency, IRIN, that the impacts of climate change had been noticeable for years and were getting worse. As the decade wore on, rising temperatures and new rainfall patterns -- droughts followed by flash floods -- increasingly drove farmers from their villages, while desertification swelled the populations of urban centers.
In a report published earlier this year, William Chemaly of the Global Protection Cluster, a network of nongovernmental organizations, international aid groups, and United Nations agencies, noted that in Burkina Faso "climate change is crippling livelihoods, exacerbating food insecurity, and intensifying armed conflict and violent extremism."
Burkina Faso can't deal with the one million people already displaced by conflict. And the world can't deal with the almost 80 million people already driven from their homes by violence. So how will we cope with 1.2 billion people -- nearly the population of China or India -- likely to be displaced by climate driven-conflicts, water wars, increasing ecological devastation, and other unnatural disasters in the next 30 years?
