Free, Prior, and Informed Consent (FPIC) is a fundamental right of Indigenous Peoples recognized under international law, particularly in the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP). It ensures that Indigenous Peoples have the right to give or withhold their consent to projects or activities that may affect their lands, territories, resources, or way of life. The principle emphasizes that this consent must be freely given, obtained sufficiently in advance, and based on a full understanding of the potential impacts of the project.
