Migration and displacements are multi-causal phenomena, and climate may exacerbate political, social, economic or other environmental drivers  . Many case studies have been conducted on the region, but data to assess and monitor precisely the effects of climate- and weather-related disasters in migration and displacements from a broad perspective remain inaccurate . The most common climatic drivers include tropical storms and hurricanes, heavy rains, floods and droughts . Positive climatic conditions also can facilitate migration . Peru, Colombia and Guatemala are among the countries with the largest average displacements caused by hydro-meteorological causes; Brazil had 295,000 people displaced because of disasters in 2019 .
