Socio-Economic Integration of Climate Migrant Families: A Study of Households Displaced by the 2010–2012 Floods and Permanently Settled in Karachi’s Peri-Urban Areas

Abstract

Climate-related displacement is increasingly shaping internal migration patterns across developing countries. Environmental disasters such as floods often destroy livelihoods, housing infrastructure, and local economic systems, forcing vulnerable populations to relocate to urban centers in search of economic opportunities and social stability. Pakistan has experienced repeated climate shocks in recent decades, with the devastating floods of 2010–2012 representing one of the largest humanitarian crises in the country's history. These floods displaced millions of people, many of whom migrated permanently to major cities, particularly Karachi. Despite the large number of internally displaced households settling in Karachi, limited empirical research has examined the long-term socio-economic integration of climate migrants within the city’s peri-urban settlements. These settlements often emerge as transitional spaces where newly arrived migrants seek employment opportunities while facing challenges related to housing insecurity, limited access to public services, and unstable income sources. This study investigates the socio-economic integration of households displaced by the 2010–2012 floods who are currently residing in Karachi’s peri-urban areas. The research specifically examines livelihood strategies, employment patterns, access to education and healthcare services, and community participation among climate migrant families. A quantitative research design was employed, and primary data were collected from 100 migrant households through structured questionnaires administered in selected peri-urban settlements of Karachi. The analysis reveals that the majority of displaced households have gradually integrated into Karachi’s informal economic sector, primarily through daily wage labor, small-scale trade, transport services, and domestic work. However, the findings also indicate persistent structural barriers that limit long-term socio-economic mobility among migrant households. These barriers include insecure housing arrangements, irregular income patterns, and insufficient access to formal education and healthcare services. Regression analysis suggests that employment stability, duration of residence in Karachi, and access to education significantly influence the degree of socio-economic integration among migrant households. Families who have resided in the city for longer periods demonstrate greater economic resilience and stronger participation in local community networks. The study highlights the need for policy frameworks that recognize climate-induced migration as a growing dimension of urbanization in Pakistan. Sustainable integration of climate migrants requires inclusive urban planning policies, improved social protection mechanisms, and targeted livelihood programs that support displaced populations in rebuilding stable urban livelihoods.
