Climate-related disasters put millions of people at risk of displacement. To effectively plan and deliver disaster risk reduction and response plans in contexts at risk of disaster displacement, governments and humanitarian agencies require good quality assessments of displacement risk. Social vulnerability is a key displacement risk factor that needs to be well integrated into assessment tools. In this good practice review, the International Institute for Environment and Development takes stock of how social vulnerability is integrated into displacement risk assessments. Finding that prominent risk assessment methodologies offer a limited account of social vulnerability, we propose a series of practical solutions.
