The global history of environmentalism, as Ramachandra Guha observes, has long been shaped by an elitist and distinctly European perspective. This dominant discourse often sidelines countries of the global South, dismissing them as merely poor and developing, and thus peripheral to the environmental narrative. In response to this imbalance, Guha introduced the concept of “Environmentalism of the Poor,” foregrounding the reality that nations in the global South disproportionately shoulder the burdens of climate change. Building on this corrective, the present chapter argues that even within these southern nations, certain groups, marginalised and exploited by their own dominant communities, bear an unequal share of environmental burdens. These underprivileged groups are frequently excluded from mainstream national conversations about nature and environmental justice. A poignant example is found in India, where Dalits and lower-caste communities have historically been relegated to the peripheries, both socially and environmentally. Mukul Sharma notes that Indian environmental history is often “written from above,” systematically erasing Dalit experiences and perspectives. Advancing this line of inquiry, this chapter introduces and explores the concept of Environmental Casteism. To illustrate and substantiate this argument, we turn to Indian literature, with a particular focus on short stories. We demonstrate how Dalits have been denied access to environmental benefits within the traditional Indian framework and are instead relegated to the margins, forced to grapple with dirt and deprivation. Furthermore, we argue that conventional environmental symbols, such as the village, commons, fire, water, and animals, take on markedly different meanings when viewed through the lens of Dalit experience.
