How droughts and floods lead to migration — and 7 things governments can do to help

Extreme water events affecting water for drinking, cooking, washing and agriculture drive migration all over the world. Earlier this year, cyclone Eloise battered Mozambique, displacing 100,000 to 400,000 people and weakening the country’s infrastructure. People displaced by the storm were in need of food, hygiene kits and personal protective equipment (PPE).

Cyclones are just one form of extreme water events that will play out more frequently and adversely as water crises worsen with climate change. Water extremes and climate change will cause more than one billion people to migrate by 2050.

Migration will be spurred by drought, as in the Sahel in Africa, shortsighted water management, as in the Aral Sea region of Kazakhstan and Uzbekistan, flooding, as in Bangladesh and small island developing states, and other extremes like cyclones.

Addressing water-driven migration will require research that crosses borders and research boundaries. As climate change continues to cause serious displacement and socio-political upheaval, governments must take action to minimize the effects on people vulnerable to migration.

The stakes of water-driven migration

Water-driven migration is a crucial challenge for people living in vulnerable and unstable regions. Water stress acts as a direct or indirect driver of conflict and migration. As water and climate extremes become worse, more people will face water crises and be forced to migrate.

For instance, take the famous case of the Aral Sea that shrank to 9,830 square kilometres in 2017 from 55,700 square kilometres in the 1970s. More than 100,000 people migrated due to collapse of agriculture, fisheries, tourism and increased illnesses such as tuberculosis and diarrhea.

Vulnerable populations bear the brunt of impacts on water availability, food production, livelihoods and income. As water and care providers, women and girls carry the burden of fulfilling water needs for their households and families. Women and girls also bear disproportionate health impacts of water crises as more hours are spent organizing household water needs.

A recent report explains that political instability, chronic poverty and inequality and climate change worsen water-driven migration. With at least 33 nations set to face “extremely high (water) stress” by 2040, it is more pressing than ever to face this problem with a strategic approach.

A seven-point strategy

Countries that have committed to the United Nations Sustainable Development Goals could address water-driven migration through SDG 16 (peace, justice and strong institutions). Policy can be aligned with SDG 16 along a seven-point strategy:

Policy-makers must prepare for the consequences of water crises by adopting improvements that address the concerns of those vulnerable to migration. The seven-point strategy calls for policy-makers to use strategic and integrated approaches between disciplines. Research that maps causes, risks and impacts at the local, regional and global levels can strengthen water migration policies.
