According to Article 2 of the Biodiversity Convention, biodiversity means “variability between organisms in all fields, including land, sea, and other aquatic ecosystems and complex ecosystems that form part of these ecosystems. This includes diversity within species, diversity among species and diversity in ecosystems.”. In other words, Biodiversity refers to the diversity of species on the planet, the diversity of the ecosystem in which they live, and the diversity of the genes of the organism.
Fresh water is water with little salt, which is about 2.5% of the water on the planet and includes lakes, rivers, rivers, and groundwater. Fresh water is of great importance considering that it is closely related to our lives, from drinking water to various agricultural and industrial waters.Specifically, freshwater organisms have limited habitat movement, so even in neighboring countries, species are organized by water system. , Diversity, distribution, etc. may differ greatly. Therefore, it is easy to preempt and claim national sovereignty over native biological resources.
Freshwater biodiversity refers to the diversity of species, ecosystems, and genes in the freshwater environment. Freshwater organisms account for only 6% of all species, but are known to be more affected than land and oceans due to a variety of anthropogenic disturbances such as climate change, habitat loss, pollution, and inflow of exotic species. According to the'World Earth Report 2014' published by the World Resources Fund (WWF), between 1970 and 2010, the Freshwater LPI decreased by an average of 76%, which is the average number of freshwater species. This means a 76% decrease compared to 40 years ago. In the future, it can be said that continuous management and preservation are more urgent.
NNIBR is a specialized research institute for freshwater organisms, and is making efforts to promote freshwater biodiversity and establish an informatization base, including research and discovery of freshwater biological resources and diversity, sample acquisition, biodiversity evaluation, and information management.
