What must be considered when one wants to understand forests is that forests have a history. That means it is necessary to also consider conditions in the area surrounding the forest when examining the changes that have taken place in the forest, and not just today's forest alone.

Forests, however, are large. (Farmland and cities also cover large areas of land, but there are many forests that are bigger.) It is most important, of course, to go to the area oneself for a detailed examination. But one person, or even a group of several people, can survey only the smallest part of a large forest. Those who want to know about the forest as a whole without a detailed examination can use remote sensing technology, which enables the examination of the forest and its surroundings at the same time.

Also, GPS and geographic information systems connect the local studies of specific points with the remote sensing studies of the overall area. These are also called 3S technology, and both technologies handle spatial information. I hope to study how this spatial information processing can be used to be of service as a tool to protect the world's forests.

The land cover changes caused by the "One million hectare rice paddy development project" in Central Kalimantan, Indonesia, was analyzed using Landsat data in 1985, 1993, and 2000. This analysis showed that a forest of 400,000 hectares in 1985 had been felled to about 94,000 hectares by 2000, a depletion of about 76%.
