wider world and an assertion of the Indigenous rights of Māori in New Zealand, this led to the Treaty of Waitangi. A majority of the Papua New Guinea population is Indigenous, with more than 700 different nationalities recognized in a total population of 8 million. The country's constitution and key statutes identify traditional or custom-based practices and land tenure, and explicitly set out to promote the viability of these traditional societies within the modern state. However, conflicts and disputes concerning land use and resource rights continue between indigenous groups, the government, and corporate entities. Indigenous rights and other issues Indigenous peoples confront a diverse range of concerns associated with their status and interaction with other cultural groups, as well as changes in their inhabited environment. Some challenges are specific to particular groups; however, other challenges are commonly experienced. These issues include cultural and linguistic preservation, land rights, ownership and exploitation of natural resources, political determination and autonomy, environmental degradation and incursion, poverty, health, and discrimination. The interactions between Indigenous and non-Indigenous societies throughout history and contemporarily have been complex, ranging from outright conflict and subjugation to some degree of mutual benefit and cultural transfer. A particular aspect of anthropological study involves investigation into the ramifications of what is termed first contact, the study of what occurs when two cultures first encounter one another. The situation can be further confused when there is a complicated or contested history of migration and population of a given region, which can give rise to disputes about primacy and ownership of the land and resources. Wherever Indigenous cultural identity is asserted, common societal issues and concerns arise. These concerns are often not unique to Indigenous groups. Despite the diversity of Indigenous peoples, they share common problems and issues in dealing with the prevailing, or invading, society. They are generally concerned that the cultures and lands of Indigenous peoples are being lost and that Indigenous peoples suffer both discrimination and pressure to assimilate into the surrounding or colonizing societies. This is borne out by the fact that the lands and cultures of nearly all of the peoples listed at the end of this article are under threat. Notable exceptions are the Sakha and Komi peoples (two northern Indigenous peoples of Russia), who now control their own autonomous republics within the Russian state, and the Canadian Inuit, who form a majority of the territory of Nunavut (created
