Climate change and displacement
Climate change, global warming and the resulting environmental pressures are among the defining challenges of our times. Climate change interacts with other global mega-trends that are conditioning the future of our planet, including population growth, urbanization, water scarcity, food and energy insecurity, and volatile commodity prices. This is adding to the scale and complexity of human mobility and displacement, and changing their patterns
Owing to this interaction, conflict and competition over scarcer natural resources will push more and more people to flee their homes or relocate to other areas. They will become displaced within their countries or across national borders. Environmentally induced migration and displacement could reach epic dimensions: predictions about the scale of such movements range from 25 million to one billion people by 2050.
