Wastewater treatment is a serious issue in Mexico City due to its large population, heavy water use, and inadequate wastewater infrastructure. Researchers supported by IDRC have published a paper where they compare the social and environmental impacts of the technology used in wastewater treatment plants in Mexico City.
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.
IDRC-funded researchers have identified coastal areas in the Nile Delta that may be vulnerable to sea level rise using Geographical Information Systems (GIS). Results indicate that significant land loss may occur in that region by 2100. Using the most recent predictions of sea level rise, total coastal land lost could be between 22 to 49%.
Researchers compared water quality available in two informal settlements in Lebanon and Jordan. Tests were conducted to compare water supplied by the municipality and bottled water. The results: tests showed that their quality is similar, although the brand of the bottled water and how it is stored affected its quality.

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.
