Eco-dystopian novels are emerging as powerful narratives that explore environmental calamity and social injustice across Asia and Africa. In China, Liu Cixin's trilogy, 'Remembrance of Earth’s Past,' critiques historical environmental policies while foreshadowing a grim future plagued by pollution and resource depletion. Similarly, Chen Qiufan's 'Waste Tide' portrays a dystopian island overwhelmed by tech waste, resonating with contemporary global issues. Nigerian author Suyi Davies Okungbowa's 'Lost Ark Dreaming' depicts a submerged Lagos, highlighting class disparities amid climate catastrophe. Indian contributions, such as Lavanya Lakshminarayan’s 'Analog/Virtual' and Varun Thomas Mathew’s 'The Black Dwarves of the Good Little Bay,' reflect a skepticism towards technological solutions, set against a backdrop of ecological devastation. These works collectively illustrate how eco-dystopian fiction not only addresses pressing environmental concerns but also serves as a medium for cultural critique, urging readers to confront the realities of climate change and envision alternative futures.
