Research framework


Strategic Research Program

Harmonization with Nature Research Program

We conduct research and technological development on the measures for conservation of biodiversity and the sustainable use of ecosystem services, which are essential for establishing a society in harmony with nature.

Basic and fundamental approaches

Foresight and Advanced Basic Research

  • Spatial Analysis of Biodiversity and Ecosystem
  • Analysis of changes in biodiversity and ecosystems
  • Analysis of the structure and function of ecosystems

Policy-Oriented Research

NIES will promote the formation of a research core for the observation and assessment of biodiversity, and enhance cooperative research network with other organizations within and outside of NIES to accumulate and analyze information related to biodiversity, including biological distribution. This will contribute to the formulation of goals for the conservation and sustainable use of biodiversity and to the understanding of the degree of achievement of these goals.

Also, the Lake Biwa Branch Office in Shiga Prefecture, which is a joint laboratory under the Regional Environment Conservation Division and the Biodiversity Division, will work with the Ministry of the Environment and Shiga Prefecture to conserve the water quality and ecosystem of Lake Biwa and its watershed.

Intellectual Research Infrastructure Development

Genome analysis and DNA barcoding

We will promote whole-genome analysis of organisms related to environmental problems and analyze the genetic diversity obtained from environmental DNA or wildlife. We have also obtained and released DNA barcode sequences for identification of species. データベース

Preservation of biological resources

Since 2002, we have cryopreserved tissues and viable cells of domestic endangered animal species in liquid nitrogen for the purpose of scientific research for biodiversity conservation and for providing the access to the materials by current and future generations. We also collect, maintain, and distribute microalgal strains and endangered algal strains.

Long-term ecosystem monitoring

We have been monitoring water quality and freshwater organisms, such as phytoplankton, zooplankton, and benthic macroinvertebrates, of Lake Kasumigaura over 40 years. We also develop new monitoring methods, analyze long-term changes in water quality and aquatic communities, and identify the factors related to these changes. In addition, in the area of genetically modified crop monitoring, we are conducting research related to the monitoring of oilseed rape to prevent it from going wild and expanding its distribution.

Development of biodiversity and ecosystem databases

Biodiversity information accumulated through research has been compiled into databases and made available on our websites. データベース

Cooperation between natural and social sciences

While research on the conservation of biodiversity and ecosystems tends to be centered on organisms and their surrounding environments, it is also important to estimate the value of biodiversity and ecosystems and establish a society to conserve them. Thus, we need a research approach from a social scientific viewpoint as well as collaboration with various stakeholders and citizens, including building a social mechanism to enhance the conservation of biodiversity and ecosystems. Based on this point of view, the Biodiversity Division conducts the following activities:

  • We established a cooperative research group based on collaboration between the fields of social science and biodiversity conservation. Researchers specializing in ecology and those specializing in social science and economics (belonging to or outside of the Social Systems and Biodiversity Division) collaborated to set up a new interdisciplinary research. Collaborative Research Group on Environmental Economics and Evaluation
  • We participate in the activities of Social Dialogue and Co-production Office and promote interactive dialogue and collaboration with various stakeholders and citizens.
  • We are conducting research projects and conservation activities in cooperation with environmental NGOs and NPOs (e.g., the Japan committee for the International Union for Conservation of Nature and International Society for Mangrove Ecosystems). 連携活動
