Transform conventional corrals3

There are many corrals along the river that are made of mud dug from the wetlands. There are no measures to reinforce these conventional corrals and the mud does not bind tight. When there are heavy rains in summer, these corrals would fall apart easily. It is very difficult for grassland of high altitude to restore balance, not to mention that these grasses were eradicated. Hence, damages due to these conventional corrals are lasting and irrevocable. In the meantime, rebuilding and repairing these corrals also require much labor input from local communities, which may repeat year after year.
