Transformation as Praxis: Exploring Socially Just and Transdisciplinary Pathways to Sustainability in Marginal Environments (TAPESTRY) The objective of TAPESTRY is to examine how transformation may arise from below in marginal environments with high levels of uncertainty. Climate change uncertainties, especially at the local level, constitute one of the main challenges to the sustainability of societies and ecosystems, calling for systemic transformative changes. While uncertainty can exacerbate anxieties about the future, it can also provide an opportunity to create transformation and deep structural change. TAPESTRY focuses on three patches of transformation in India and Bangladesh - vulnerable coastal areas of Mumbai, the Sundarbans and Kutch - where hybrid alliances and innovative practices are reimagining sustainable development and inspiring societal transformation. TAPESTRY is organised in a transnational and transdisciplinary consortium across the UK, India, Bangladesh, Norway and Japan. Its conceptual innovation lies in studying transformation as praxis, by putting bottom-up change and the agency of marginalised people at the centre and by analysing how co-produced transformations can be scaled up and out. The project is particularly relevant to theme 1 and 3 of the call, i.e. governance, wellbeing, quality of life, identity and values in relation to transformations to sustainability. All these lie at the heart of the welfare and development challenges faced by India (a lower middle income country) and Bangladesh (least developed country). The project's outcomes and impact will inform processes to improve the quality of life of marginalised people affected by climate change related uncertainties, build action and capacity amongst all partners whilst generating evidence of how bottom-up transformation can take place in marginal environments. The Global Challenges Research Fund (GCRF) supports cutting-edge research to address challenges faced by developing countries. The fund addresses the UN sustainable development goals. It aims to maximise the impact of research and innovation to improve lives and opportunity in the developing world.
