In many parts of the world climate change can seem a secondary concern compared to immediate problems of poverty, food security or conflict. But changes in the world’s climate can have an increasing impact on access to water and land.

Risks of mass migration as a result of flooding, droughts or other climate related natural disasters, may lead to destabilising population movements which will pose huge challenges locally and internationally.
