In Melanesia, the Tambu (also spelled Taboo or Tapu) system offers a powerful, time-tested model for sustainable living. These systems govern access to places or resources based on cultural or spiritual customs. For example, a reef might be closed to fishing following the death of a chief, remaining off-limits during a period of mourning and cultural protocol, and only reopened either to prepare for the funeral feast or after it has taken place. The result? Fish populations have time to recover and replenish.

The Piku Biodiversity Network (PBN) is intensifying its efforts to protect sawfish and rhino rays in Papua New Guinea's Kikori River Delta, collaborating closely with local fishers and conservation partners. These species, once abundant in the region's waterways, now face critical endangerment due to habitat loss and fishing pressures. By engaging communities in active conservation, PBN aims to balance sustainable livelihoods with biodiversity preservation.

In 1975, when Papua New Guinea gained independence, our founding leaders envisioned a nation built on unity, self-reliance, and sustainability. This vision was enshrined in our 5 National Goals and Directive Principles, forming the foundation of our National Constitution. As we celebrate 50 years of independence, it is a moment to reflect on these guiding principles and how they continue to shape our country today.
