Wengki Ariando's presentation at the Van Vollenhoven Institute, Leiden University, emphasizes the crucial role of Indigenous Peoples and Local Communities (IPLCs) in the global response to the climate crisis. It highlights that IPLCs are not just vulnerable populations, rather, they are essential stewards whose land-sea management practices contribute significantly to carbon sequestration and biodiversity preservation.

A key aspect of their resilience is Traditional Ecological Knowledge (TEK), a comprehensive body of knowledge, practices, and beliefs developed over generations. The presentation explores how TEK facilitates effective climate change adaptation by providing localized solutions that are often overlooked by modern Western science. It also traces the journey of IPLCs within the UNFCCC (policy and movement), showcasing their evolution from marginalized observers to recognized stakeholders. This shift reflects a growing global acknowledgment of Indigenous rights and wisdom.

The presentation concludes with a case study of the Sea Nomads (Orang Laut, Moken, and Sama-Bajau), illustrating their unique relationship with marine ecosystems and everyday challenges. It demonstrates how their specialized TEK empowers them to adapt to rising sea levels and shifting marine biodiversity, presenting a valuable model for marine-based climate adaptation strategies.
