This policy brief summarizes the findings of a joint study by the International Organization for Migration (IOM) and the Stockholm Environment Institute that examined links between climate change and international labour migration. In Thailand, the study focused on workers from Cambodia and Myanmar employed by smallholder farmers on sugarcane plantations in Sa Kaeo and Tak provinces. The purpose of this brief is to provide insights to the Royal Thai Government on the conditions under which workers are migrating, their experiences in Thailand, and the implications of their migration for climate resilience and human well-being. The brief also provides recommendations to strengthen policies and suggests potential ways to improve business practices.
