This chapter examines the complex interplay of poverty, climate change and migration as experienced by marginal farmers and rural labourers from Morrelganj, southwest Bangladesh, migrating to Indian cities for work as ragpickers and domestic workers. Despite their irregular migrant status, they identify closely with their destination due to cultural affinities, viewing India less as a foreign land and more as an extension of their community. Through ethnographic research in sending villages, the study highlights how environmental changes, particularly riverbank erosion and extreme weather events, exacerbate existing economic vulnerabilities, compelling individuals to seek livelihoods in India’s urban centres. The narrative also delves into the contrasting perceptions of these migrants, who see their migration as legitimate and necessary, versus the Indian authorities and societal segments, increasingly influenced by xenophobic and Islamophobic sentiments, who view them as threats. The chapter sheds light on the resilience and agency of these migrants in navigating the socio-economic and political challenges of their informal, transnational lives, underlining the broader implications of environmental distress and restrictive migration policies.
