Papua New Guinea (PNG) was first settled between 50,000 and 60,000 years ago. PNG’s harsh geography consisting of mountains, jungles, and numerous river valleys, kept many of the arriving groups isolated, giving rise to PNG’s significant ethnic and linguistic diversity. Agriculture was independently developed by some of these groups. Around 500 B.C., Austronesian voyagers settled along the coast. Spanish and Portuguese explorers periodically visited the island starting in the 1500s, but none made it into the country’s interior. American and British whaling ships frequented the islands off the coast of New Guinea in the mid-1800s. In 1884, Germany declared a protectorate - and eventually a colony - over the northern part of what would become PNG and named it German New Guinea; days later the UK followed suit on the southern part and nearby islands and called it Papua. Most of their focus was on the coastal regions, leaving the highlands largely unexplored.
The UK put its colony under Australian administration in 1902 and formalized the act in 1906. At the outbreak of World War I, Australia occupied German New Guinea and continued to rule it after the war as a League of Nations Mandate. The discovery of gold along the Bulolo River in the 1920s led prospectors to venture into the highlands, where they found about 1 million people living in isolated communities. Japan invaded New Guinea in 1941 and reached Papua the following year. Allied victories during the New Guinea campaign pushed out the Japanese, and after the end of the war, Australia combined the two territories into one administration. Sir Michael SOMARE won elections in 1972 on the promise of achieving independence, which was realized in 1975.
A secessionist movement in Bougainville, an island well endowed in copper and gold resources, reignited in 1988 with debates about land use, profits, and an influx of outsiders at the Panguna Copper Mine. Following elections in 1992, the PNG Government took a hardline stance against Bougainville rebels and the resulting civil war led to about 20,000 deaths. In 1997, the PNG Government hired mercenaries to support its troops in Bougainville, sparking an army mutiny and forcing the prime minister to resign. PNG and Bougainville signed a truce in 1997 and a peace agreement in 2001, which granted Bougainville autonomy. An internationally-monitored nonbinding referendum asking Bougainvilleans to chose independence or greater self-rule occurred in November 2019, with 98% of voters opting for independence. However, the PNG Government and Bougainville officials remain in negotiations about the status of the island.

the indigenous population of Papua New Guinea (PNG) is one of the most heterogeneous in the world; PNG has several thousand separate communities, most with only a few hundred people; divided by language, customs, and tradition, some of these communities have engaged in low-scale tribal conflict with their neighbors for millennia; the advent of modern weapons and modern migrants into urban areas has greatly magnified the impact of this lawlessness
rain forest loss as a result of growing commercial demand for tropical timber; unsustainable logging practices result in soil erosion, water quality degredation, and loss of habitat and biodiversity; large-scale mining projects cause adverse impacts on forests and water quality (discharge of heavy metals, cyanide, and acids into rivers); severe drought; inappropriate farming practices accelerate land degradion (soil erosion, siltation, loss of soil fertility); destructive fishing practices and coastal pollution due to run-off from land-based activities and oil spills

note: paved runways have a concrete or asphalt surface but not all have facilities for refueling, maintenance, or air traffic control; the length of a runway required for aircraft to safely operate depends on a number of factors including the type of aircraft, the takeoff weight (including passengers, cargo, and fuel), engine types, flap settings, landing speed, elevation of the airport, and average maximum daily air temperature; paved runways can reach a length of 5,000 m (16,000 ft.), but the “typical” length of a commercial airline runway is between 2,500-4,000 m (8,000-13,000 ft.)

note: unpaved runways have a surface composition such as grass or packed earth and are most suited to the operation of light aircraft; unpaved runways are usually short, often less than 1,000 m (3,280 ft.) in length; airports with unpaved runways often lack facilities for refueling, maintenance, or air traffic control
