Recent studies show that water shortages in Central America and the Caribbean will be aggravated by urban growth, high poverty rates, weak institutions, and insufficient investment in water and sanitation infrastructure.
The Mantaro Valley in central Peru is highly vulnerable to extreme weather events, such as droughts, floods, and frost. According to recent projections, this vulnerability will increase in coming years due to climate change.
Research shows that weather-related emergencies, such as floods, significantly increase internal migration in Costa Rica. An increase of one hydro-meteorological emergency raises migration rates between 0.7 and 0.11 percentage points. Therefore, migration can be a potential adaptation strategy when faced with weather-related emergencies, with people moving to less vulnerable places.
