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.
From 2006-2012, 212 organizations participated in research supported by the Climate Change Adaptation in Africa (CCAA) program. Despite the lack of African institutions working on climate change issues prior to the CCAA program, some 89% of these organizations are based in Africa, and now represent one of CCAA's key results: a strong base of African expertise to conduct and communicate research on adaptation to climate change. Following CCAA funding, mentoring, and opportunities to work with international experts, these institutions and their researchers are now recognized by communities and governments in Africa and beyond as go-to experts to inform adaptation initiatives, programs, and policies.
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.
One important challenge facing post-secondary institutions today is how to transform themselves into agents of sustainability. In the last decade, a number of initiatives in Canada set out strategies and forums to share experiences and best practices and to advance teaching and research for social and environmental sustainability. But few of these provided an opportunity to engage with institutions in developing countries.
When a neighbourhood is at risk of flooding, the most logical solution is to build new houses in more secure areas and to relocate the residents. But in Dakar, the capital of Senegal, things are not so simple.
Morocco is a partially arid country where rain is rare but where agriculture prospers in spite of everything. Climate change has nevertheless had a major impact on Morocco in recent years. Precipitation has decreased by 20%, and heat and cold waves are increasingly frequent.
