River deltas are vital ecosystems supporting rich biodiversity, unique cultural traditions, and millions of livelihoods through fisheries and agriculture while also serving as critical buffers against storm surges and coastal erosion. Central to the development of the modern global trade and eco-system, they are increasingly threatened by climate change impacts; sea-level rise, altered river flows, extreme weather events and continuing forms of colonial and ethno-nationalist exploitation to name just a few. In this seminar, we will discuss the past and future of deltas and how we can ensure a sustainable future for their communities, biodiversity, and entire ecosystems.
