• Migrants are sustainability actors in their urban destinations. • Sustainability policy overlook the transformative role of migrants. • Technocratic and assimilationist notions dominate sustainability policy discourse. • Sustainability policy should embrace migration and plurality. Although it is widely recognized that migration is socially transformative, the potential contributions of migrants to transformations towards sustainability in their destination areas are often overlooked in mainstream discourse on environmentalism and sustainability. Here we seek to identify current narratives of migrants and sustainability across individual, urban, and national scales. Migrants are commonly framed in public policy as having no or even negative impacts on sustainability. The study hypotheses that the lived experience of sustainability by migrants within urban destinations differ from dominant discourses and perceptions of migrant populations within societies. We test and document such divergence using data from 21 interviews with key stakeholders from the city and Swedish national level, an attitudinal survey of 895 migrants and non-migrants in Malmö, Sweden; and a media analysis of local and national Swedish newspapers. Survey results show that migrants engage more extensively with a number of sustainability actions compared to non-migrants culminating in new insights on 'migrants as sustainability actors'. By contrasting individual scale practices against urban to national sustainability narratives, the study illuminates current barriers to and the potential of migrants to play a transformative role in progress towards sustainability that is unrecognized in dominant policy discourses. To tap into this potential, the study emphasizes that sustainability policy across scales should embrace plurality and migration as fundamental parts of progress towards sustainability.

• Migration has simultaneous offsetting positive and negative effects on sustainability. • Migration affects sustainability in environmental, social, and economic dimensions. • Migration contributes to sustainability if it increases well-being and reduces inequality and environmental burden. • If policies for sustainable development incorporate migration, they yield significant synergistic benefits. Migration represents a major transformation of the lives of those involved and has been transformative of societies and economies globally. Yet models of sustainability transformations do not effectively incorporate the movement of populations. There is an apparent migration-sustainability paradox: migration plays a role as a driver of unsustainability as part of economic globalisation, yet simultaneously represents a transformative phenomenon and potential force for sustainable development. We propose criteria by which migration represents an opportunity for sustainable development: increasing aggregate well-being; reduced inequality leading to diverse social benefits; and reduced aggregate environmental burden. We detail the dimensions of the transformative potential of migration and develop a generic framework for migration-sustainability linkages based on environmental, social, and economic dimensions of sustainability, highlighting identity and social transformation dimensions of migration. Such a model overcomes the apparent paradox by explaining the role of societal mobility in achieving sustainable outcomes. [ABSTRACT FROM AUTHOR]

• Sustainability transitions are challenged by the social dynamics of people moving. • Migration is a driver of sustainability practices in low income urban settings. • Indepth study of sustainability practices using life histories in Accra. • Sustainability practices vary between internal and international migrants. • Transformation processes among internal and international migrants are not uniform. Development that is inclusive and sustainable requires significant social and environmental transformations from current trajectories, building on demographic realities such as changing profiles of populations, and increased levels of mobility. Migration is a major driving force of urbanisation in all global regions, partly facilitated through emerging technologies and declining costs of movement and communication. Social transformations associated with increased migration are highly uneven but include shifts in the location of economic activities, major urban growth, and changing individual incentives and social constraints on sustainability trajectories. Yet, there is limited empirical evidence on how observed population movements can both challenge and promote sustainable transformations. This paper examines how migration transforms places and societies, by providing new evidence on the behaviours and practices of individuals who are part of such transformations as they assimilate, converge or remain distinctive to prior populations. Focusing on individuals in rapidly expanding cities in the Global South, this study uses new biographical life-history survey data from Accra, Ghana, to examine the barriers and enablers of sustainability practices among diverse types of migrants and a sample of non-migrants. The study uses data from 1,163 individuals: international migrants from the West African sub-region (5 5 9), internal migrants (2 9 9), and non-migrants (3 0 5) in Accra. The findings show that sustainability practices established before migration are predictors of current sustainability practices, including proactive recycling, conservation activities, and choice of mode of transportation, but that there is some convergence between behaviours, reflecting assimilation, place attachment and other factors. Internal migrants in Accra exhibit stronger sustainability practices than international migrants. Individual levels of poverty, poor infrastructural development, and perceptions about life satisfaction in the neighbourhood negatively affect sustainability practices among all respondents. These results suggest that poverty and social exclusion are critical to addressing sustainability issues in urban contexts. It is important for policy makers to address issues of urban poverty, cumulative deprivation, and inequality as strong barriers to the adoption of sustainability practices in urban areas.

Research on the impact of violence and conflict on education typically focuses on exposure among a cohort of school-aged children. In line with the fetal origins hypothesis, this paper studies the long-run effect of exposure to adverse maternal health shocks while still in the womb. Exploiting the sudden and discrete nature of the Rwandan genocide and an identification strategy based on temporal and spatial variation, we find that the cohort in utero during the genocide reported on average 0.3 fewer years of schooling in the 2012 Rwanda. Population and Housing Census and was 8% points less likely to finish primary school relative to the cohort in utero just a couple of months later. [ABSTRACT FROM AUTHOR]
