Planting activities in the former Matsuo mine wasteland area by utilizing fisheries waste products

Activity grant

Project Description

We will try to solve the following two problems for the former Matsuo mine site: obstacles restoring vegetation due to acidic soil and acidic water flowing upstream from Kitakami river in Iwate prefecture; and oyster shell and seaweed residue, which is a downstream fishery waste product of Miyagi prefecture. We will take action that includes utilizing oyster shells as a neutralizing agent for acidic soil, utilizing seaweed/bark as fertilizer, and planting Betula ermanii at the mining site. This experience will also be used for environmental learning.

Establishment purpose
For this environmental problem, it is necessary for many residents to show accurate judgment using correct information, and it is essential to act towards solutions while conscious of global environmental problems. As experts on environmental problems, we will give back the knowledge and technology we have cultivated to local communities and residents. We aim to continuously carry out activities to fundamentally solve both regional and global environmental problems by implementing support based on academic knowledge of environmental measures and environmental education.

Main Activities
We have been engaged in water purification, biodiversity conservation research and environmental conservation activities for Izu-numa, implementing the "Ikizuku Lake and Contact Interpretation Model Project" commissioned by the Ministry of Environment for three years from fiscal 2005. Since fiscal 2008, as a voluntary initiative, we have continued research and activities related to Izunuma's environmental conservation up until present. In addition, in 2008, we carried out activities to improve the quality of small rivers flowing into Seki-dam in Rifu-town, Miyagi prefecture. One activity was to plant Carex dispalata in collaboration with the local Carex dispalata society to purify the river water. Another activity involved using water from the Agawanuma, an agricultural pond in Shichigahama, Miyagi Prefecture Shichigahama. In this activity, we grew Luffa (type of cucumber) together with elementary school students and while observing the growth we conducted environmental education to think about water pollution.
