As youth climate activism grows around the world, this project will generate unique understandings into how families composed of first and second generation immigrants from the Global South (GS) are responding to lived experiences of climate crisis in two ethnically diverse cities: Manchester and Melbourne. As well as growing up at a historic crossroads in terms of political and societal responses to the climate crisis, second generation immigrants are at an additional crossroads in their family life, between sets of political and cultural values, economic possibilities and environmental characteristics that have roots in (at least) two countries. This pioneering project will be the first of its kind to conduct research with this often overlooked group of young people, generating insights from two cities, with young people from a range of ethnic backgrounds. The question at the heart of the project is how second generation immigrants - part of the most 'climate change-aware' generation alive today - discuss and negotiate responses to the climate crisis with parents who may have first-hand experience of living with resource and climate uncertainty, yet whose knowledge is often not valued in Global North (GN) contexts. This area of research is both timely and important because at a time when deep-rooted adaptations are urgently needed in societies already feeling the effects of climate change, GS immigrants hold valuable knowledges that are often not known to or fully appreciated by the public and by policy makers in the GN contexts where they are living. Existing research with adult immigrants in the GN has found that immigrants show a higher disposition towards 'sustainable' practices such as reducing household waste, using water sparingly, and walking or cycling over driving. As cities seek to meet ambitious sustainability agendas and as city residents increasingly feel the effects of climate change, the knowledge and experience of GS immigrants can offer insights into how to respond to drought, extreme weather and other effects of climate change. The role of young people in carrying environmental education messages from schools to homes is well researched and documented (including by the PI). However, an important but largely unexplored area is how second generation immigrants respond to and make parents' knowledge of living with climate uncertainty known in schools, where such knowledge can enrich and diversify existing climate change education. The project will employ an action research methodology that will support young people's participation by training them to carry out research in their homes and work with parents, peers, teachers and researchers. The action research will result in a toolkit documenting resources for diversifying education on climate change (among other outputs). This has the potential to benefit students, teachers, policy-makers and environmental NGOS, and in particular second generation immigrants and their families as the valuable knowledge they hold is recognised, debated and applied in Manchester, Melbourne and beyond. Concurrently, the project will make important academic contributions to the fields of environmental politics, political geography and critical environmental education through publications in leading social scientific journals, the PI's first monograph and presentations at international conferences. These academic outputs will position the PI as a leading researcher who is uniquely positioned at the intersection of these fields. The research will furthermore strengthen international networks that the PI and mentors have begun to build through their existing research into environment, sustainability and migration. At a time when knowledge on how to respond to the 'wicked challenge' of climate change in diverse societies is more needed than ever, the research has significant potential to lead to further international collaborations to advance this important and unique area.
