“The special law” on the environmental conservation of the Seto Inland Sea, Japan and governmental basic plan for the environmental conservation of the sea based on the law were both revised recently in 2015. Two major aims of the previous basic plan (1. conservation of water quality, 2. conservation of natural landscape) were reformed to broaden four new major aims (1. conservation and restoration of coastal environment, 2. conservation and appropriate management of water quality, 3. conservation of natural and cultural landscapes, 4. sustainable utilization of fish resources) in the revised basic plan. Historically, environmental management policy of the Seto Inland Sea had firstly made emphasis on water pollution control such as total pollution load control (TPLC). However, this kind of passive conservation policy is gradually being sifted recently to active conservation such as Satoumi which includes restoration of biodiversity, biological productivity, habitat and well balanced nutrient cycle between land and sea. Holistic approaches such as integrated coastal management (ICM), ecosystem-based management (EBM) and adaptive management were incorporated into new policy in Japan. These clear changes of management policies of the Seto Inland Sea will make change more detailed policy of every related prefecture and hence will promote Satoumi activities in near future.

Important Position

The northern Shikoku region is located in the Western part of Japan and faces towards the Seto Inland Sea. The forest area, which is one of the non-point sources in the Seto Inland Sea watershed, occupies 75% of the land use in the watershed of the northern Shikoku region. The amount of loadings of nutrients and COD in the Seto Inland Sea has been estimated by the unit load method but actually the data has not been investigated. It is however, necessary to know the real concentration of nitrogen in mountain streams to evaluate the role which is the mountain area plays as non-point sources. Therefore, more water samples of mountain streams in the watershed need to be taken and the concentrations of nitrogen analyzed. The mountain streams in the northern Shikoku area were investigated from April, 2015 to November, 2015. The number of sampling sites was 283, in addition to the past data by Kunimatsu et al. The average concentration of nitrate nitrogen in Ehime, Kagawa, and Tokushima was 0.61mg/L, 0.78mg/L and 0.34mg/L, respectively. The environmental standard range for nitrogen in the Seto Inland Sea is from between less than 0.2mg/L and less than 1mg/L. Therefore, the average concentration of nitrogen in these regions was over category II, and those of mountain streams in Kagawa Prefecture exceeded category III. About 20% of mountain streams were more than 1mg/L. It has become clear that mountain areas occupy an important position as non-point sources for the Seto Inland Sea.
