This study looks at the different forms that child marriage takes in South Asia and further looks at how these variations in child marriage practices are linked to other harmful practices. The study acknowledges that child marriage takes place in various forms and that these variations in child marriage practices are linked to other harmful practices. It describes the impact that programmes seeking to address child marriage may be having upon other harmful practices, such as polygamy, honour crimes and dowry-related violence, bride price and dowry, sex selection and female infanticide, menstruation practices, caste-based discrimination, and child labour. By identifying these linkages, programmes can be better informed about the potential impact of their interventions and can reflect on whether there are additional considerations that need to be taken into account.
