There are a number of countries for whom migrant workers are a key political and economic issue. Nepal is one of those countries, with 3.5 million of its citizens working in the Middle East, Malaysia, and India, contributing nearly one-quarter of the country’s gross domestic product. The plight of migrants workers was put under a global spotlight in the run up to and during the 2022 FIFA men’s football World Cup. Migrant workers from South Asia, including Nepal, have helped build the stadiums and roads leading up to it, provided the security at venues, take the suitcases of the conveyor belts at the airports, and served fans and visitors food and drink at the venues. Many migrant workers are exploited by employers in the Gulf countries and Malaysia and/or labour agencies in their home countries. This research brief offers an overview of studies into the health and well-being of Nepalese migrant workers and those left behind conducted by researchers based at Bournemouth University in the UK in collaboration with two NGOs (Non-Governmental Organisations) Green Tara Nepal and POURAKHI Nepal, and several UK universities.
