| Research Abstract |
Time-spatial analyses of archaeological sites and soil analyses in the area affected by successive volcanic eruptions were made in order to reveal a recovery process of soil fertility. Around Mt. Kaimondake, Japan, it was cleared using GIS that the development of agricultural lands had been driven after its AD7C eruption and that the lands had been devastated by the AD874 eruption. Around Mt. Vesuvius, Italy, the buried Somma Vesuviana paleosols had a relatively high ability to supply nutrients and they were fertile prior to the AD472 eruption. Around Mt.Pinatubo, Philippine, it was newly found that swidden cultivation and plants with root nodule bacteria could contribute to the recovery of soil fertility.
