This chapter explores the meaningful implications of Indigenous knowledge systems to deal with human-created climate crisis adaptation strategies, focusing on land-based practice, Indigenous sovereignty, and youth-led initiatives. The chapter examines how the Monda Indigenous communities in the coastal area are struggling with the human-created climate crisis such as land grabbing, displacements, profit-oriented fish farming, clearing natural forests for profit, and only western forest management by the mainstream people and their profit. This chapter also highlights how the traditional land-based knowledge and spirituality approach—a critical framework that brings Indigenous communities self-determination and climate justice—enhances climate resilience. Through a focus on intergenerational land-based learning, the chapter highlights the importance of land-based culture and practice in protecting cultural practices and creating environmental stewardship across generations. It also addresses the central role of Indigenous sovereignty in climate governance, where communities assert control over their land as part of climate adaptation strategies. The chapter explores how climate justice frameworks, informed by decolonial perspectives, can address the disproportionate impacts of climate change on marginalized communities, particularly Monda Indigenous peoples. This chapter aims to provide a comprehensive understanding of how Indigenous knowledge and governance systems offer sustainable solutions to human-created climate crises, promoting both cultural revitalization and climate resilience.
