Should it be successful, the law would be the first of its kind in Latin America and the Caribbean, a region where the World Bank’s estimates there could be as many as 17 million internal climate migrants by 2050, representing 2.6 percent of the region’s total population.  

While the new law only addresses internal climate displacement, it could have significant regional implications as countries continue to step up efforts to address both internal and cross-border movement due to the effects of climate change.
