Settlement history and Population trends 1947 -2005 NOW OVER 8,000!!! Colonial Era, permanent settlement was prohibited Early 1980 policy changed and permanent resident was allowed, leading to gradual increase in the atoll’s population Early 1990s resettlement scheme began and thus rapid population growth between 2000 and 2005 Ecological Benefits

Become party to the Ramsar Wetland Convention – designate Kiritimati Atoll or Critical areas as a Ramsar Site Conclusion
The limited terrestrial, but abundant seabird, land crab and fisheries resources have, for generations, been the foundation for socio-economic, health and food security of the atoll people of Kiritimati.
The status of living resources and their habitats have, however, been changed and seriously degraded over a time scale. Conclusion (cont.)
This has critically threatened the livelihoods and cultural identity of the more than 6,000 inhabitants and sustainable development
Increasing awareness of the value of biodiversity, promoting better measures of biodiversity conservation and sustainable use, and improving coordination of national, regional and international conservation efforts can promote sustainability for the benefit of future generations Closing Remarks – Wisdom of the Elders • The older men and women ( unimwane and unaine ) strongly supported for this study.
• They revealed and expressed their experiences of how the past was so undisturbed, full of life with rich marine and wildlife resources.
• They feel that their once peaceful and colorful world that they treasured had been shattered over time through unsustainable activities of the increasing population and technological advances that have been incompatible with nature. Closing Remarks • Current conservation measures and capacity of concerned bodies are inadequate or defunct and something must be done.
• They hope to see the revival of the past and protection of the endangered species that were once their close and well- known neighbors.
• They strongly believe that effective strategies with the participation of all key actors and international intervention is their only hope towards restoration of a healthy terrestrial and marine environment of Kiritimati Atoll with diverse biological components functioning in balance and supporting a wide range of sustainable human economic and social activities.
