Information on biodiversity is valuable and necessary for advancements in science. Further, similar to intellectual resources in other disciplines, it is highly beneficial for all. This information can be put to practical use for training future generations of scientists to lead scientific progress. Moreover, while skilled users can utilize updated knowledge and technology gained from advances in biodiversity sciences, amateur naturalists can simply enjoy biodiversity, and its products and scientific knowledge.

　Borneo Island is the center of biodiversity in tropical Asia. The State of Sarawak, one of the Malaysian states in Borneo, is home to tropical rainforests with prominent species-rich biodiversity, including Burung Kenyalang (rhinoceros hornbill) and Rajah Brooke's birdwing (birdwing butterfly). In recent decades, the Sarawak Government has expanded the area of national parks, the number of which exceeds 30, to approximately 800 hectares for the conservation of the tropical rainforest. However, scant information is available regarding the entire biodiversity in the area spanning the tropical rainforests in Sarawak. We speculate that many species remain undiscovered or undescribed even for well-studied taxa of plants, animals, and microorganisms. In addition, the shortage of information on biodiversity prevents local residents from recognizing the overall benefit from the biodiversity in tropical rainforests in these protected areas. Hence, it is believed that they do not have an adequate understanding on its importance and the benefit of conservation, apart from the related traditional knowledge.

　PUBS, a joint project between Sarawakian and Japanese research organizations, will launch several long-term projects that aim to elucidate the entire biodiversity of the region, including gamma diversity of species richness, genetic diversity within and between local communities, ecological diversity in interspecific interactions, and the inhabitation status of wildlife in tropical rainforests of Sarawak, among others. For the efficient implementation of these long-term projects, PUBS will introduce high-end technology such as DNA barcoding using next-generation DNA sequencers to Sarawakian research organizations, and initiate these projects by conducting both intensive field surveys as well as molecular biology analyses. The data and outputs from the implementation of the projects will be uploaded on the platforms, and the archives of stored data, samples, and specimens will be used to develop a complex of museums and libraries for scientific, educational, and industrial utilization of the information on biodiversity in Sarawakian tropical rainforests. The platforms will make it easy for everyone to access and use updated information on the biodiversity in this region.

　PUBS welcomes local residents to participate in the various programs of the project that will provide them experience in research activities and share updated knowledge in the field of biodiversity sciences. We are convinced that such participation will eventually contribute to the development of human resources in a wide range of sectors in society.
