IT （Information Technology） has been put to practical use in all fields, and in the agricultural sector, various IT-based new technologies are being implemented, as exemplified by the term smart agriculture. In order to advance smart agriculture, it is important to link farmland parcels information （Polygons of Land Parcels） with IT. Polygons of Land Parcels were developed by the Ministry of Agriculture, Forestry and Fisheries as population information for a survey of arable land area, but was later released as open data and is now used for a variety of purposes.

Establishing a safety culture requires each organization member to recognize these lessons personally, continuously enhance safety awareness, and maintain a constant attitude of self-questioning for safety even in peacetime.

Rapid responses to frequent, severe natural disasters are vital for prevention and recovery. This report highlights challenges in damage assessment and initial responses, focusing on "location," "people," and "information." It suggests using remote sensing（ satellite SAR, UAVs） and GIS. Satellite SAR detects surface changes, UAVs perform detailed risk-free surveys, and GIS integrates data, improving response speed and accuracy. On the other hand, although each technology still has remaining challenges, they can be addressed through future technological developments, and their versatility is expected to expand.
