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 .

Cyclones are just one form of extreme water events that will play out as water crises worsen with climate change. Water extremes and climate change will cause .

Migration will be spurred by drought, as in , shortsighted water management, as in of Kazakhstan and Uzbekistan, flooding, as in , 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 . As water and climate extremes become worse, more people will face water crises and be forced to migrate.

For instance, take the 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 . 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 as more hours are spent organizing household water needs.

explains that political instability, chronic poverty and inequality and climate change worsen water-driven migration. With , 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 (peace, justice and strong institutions). Policy can be aligned with SDG 16 along a seven-point strategy:

1. Address the connection between water ownership, distribution and migration: . To capture the scope of water issues, future research must .

2. Understand how water crises influence migration: Causality is important in addressing migration. Land, water and human security issues could serve as a base for outlining a preventative outlook for new and emerging migration pathways.

3. Integrate diverse perspectives in water migration assessments: Water co-operation treaties must integrate under-represented, marginalized and racialized migrant voices. The has developed an approach to aggregate the causes and consequences of water-driven migration. This framework can help policy-makers interpret migration in diverse socio-ecological, socio-economic, and socio-political settings.

4. Assess water, migration and development practices through participatory, bottom-up and interdisciplinary approaches: Research should be , and socially inclusive to complement scientific, descriptive methods. Nuanced facts of the diverse influences that shape migration can provide understanding to build resilience among vulnerable populations.

5. Manage data, information and knowledge: Researchers need updated data to examine how water crises are linked with human migration. To close the gaps, to improve capacity for data analysis within and between countries. Also, there must be stronger co-ordination at the state, regional and international levels to share best practices.

6. Apply a gender-sensitive lens: The economic, health and societal effects of water-driven migration affect . Filling these knowledge gaps will require a . Namrata Chindarkar, a water and public policy researcher, that comprehensive and holistic investigations of the states people come from, end up in and transit through must be gender-sensitive if they are to be inclusive.

7. Understand water, migration and peace: There is potential for . Broader approaches could help examine key links between water, migration and peace.

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.
