Collaborative Adaptation Research Initiative in Africa and Asia

Some parts of the world are especially vulnerable to the extreme effects of climate change.


Sea level rise, changes in precipitation patterns, and glacial melt endanger the livelihoods of large numbers of poor people. Semi-arid regions, deltas, and glacier- and snowpack-dependent river basins are three such climate change “hot spots”.

The Collaborative Adaptation Research Initiative in Africa and Asia (CARIAA) builds the resilience of vulnerable populations and their livelihoods in these hot spots by supporting collaborative research on climate change adaptation to inform policy and practice. CARIAA takes a unique approach by organizing research around four consortia that bring together more than 450 researchers and postgraduate students affiliated with 18 member institutions and more than 40 partner organizations. Each consortium focuses on research related to one of the three climate change hot spots in 14 countries in Africa and Asia.

IDRC and the UK’s Department for International Development (DFID) are partnering to support this program, which runs until 2019. The experience and lessons learned through their earlier joint climate change effort, the Climate Change Adaptation in Africa program (2006-2012), have provided insight and guidance for CARIAA’s mission.

Climate change hot spots

What do Bira, Chatti, Seydou, and Shilpi have in common? They are four of the more than one billion people living in hot spot regions — deltas, semi-arid lands, and glacier and snowpack-dependent river basins in Africa and Asia — that are most vulnerable to climate change.

1.5°C warming

With 1.5°C warming, at least a quarter of the ice on the Himalayan mountains today will be lost, affecting 13% of the world’s population. Learn more

The impact in low-lying deltas will not be measurable until around the 2040s, when the area of land under inundation is expected to be about 2.5 times larger. Learn more

Semi-arid lands will also experience high variations in precipitation, with significant impacts on power production, agriculture and health. Learn more
