Abstract
The Graduate School of Agricultural Science, Tohoku University,
launched an Agri-Reconstruction Project in
2011
immediately after the March 11
Great East Japan Earthquake disaster, and this continues to date. The project's
objective is to support the agricultural, forestry and fi sheries reconstruction process
in the tsunami disaster area. The activities have been implemented through more
than 40 research projects along the Tohoku region including the Rapeseed Project
for Restoring Tsunami-Salt-Damaged Farmland.
Immediately after the disaster, damaged farmlands were surveyed and salt-
tolerant rapeseed varieties from Brassicaceae and related species were used to
restore the soil. The plants came from the gene bank developed at the Graduate
School of Agricultural Science, and were planted on damaged farmland in Sendai,
Iwanuma and Higashi Matsushima cities. The varieties used to restore the soil
depended on the specifi c damage.
As part of the project, the production and sale of edible as well as fuel oil obtained
from rapeseed plants was organized in coordination with the Miyagi Prefecture
Sendai City government, a number of private companies and other partners. This
enterprise continues to date.
Besides using the salt-tolerant varieties of Brassicaceae plants in tsunami-
damaged fi elds they are also used overseas in the rehabilitation of salt-damaged
farmlands.
