| Outline of Final Research Achievements |
We examined sustainable low-cost measures to control erosion of gully and riverbanks through the on-site evaluation of models site works adopted by the JICA water-induced disaster prevention projects of 15-20 years ago in Nepal. Gabion check dams and bamboo plantation in combination with plantation of useful grass on barren slopes have been well protecting the devastated lands from gully erosion in the Midland. Embankments keeping the original width of the river can have stabilized the previous riverbed level, thus promoting an increase in population around the river. It is also notable that community-based land management and execution of preventive works including reforestation is essential for effectiveness of adopted hardware measures.
