Soil Information System (SIS) provides not only relevant soil information related to crop productivity, but also wide-ranging useful data such as, assessment and conservation of environmental quality, wildlife habitats, and global warming and energy concerns. USA and Europe have, in particular, strengthened the latter aspects in their SIS. The USDA-NRCS, for instance, provides not only fundamental soil data, but also energy- and money-saving strategies for relevant cultural practices for web-users. The EU has followed suit, launching the European Soil Portal in 2004, and has started providing a variety of natural resources information for the region.
In Asia, on the other hand, only a few countries have established their own SIS, chiefly consisting of computer-based soil map associated with detailed analytical soil data. However, they make public, at most, only a few relevant data on their website.
SIS is undoubtedly a very useful tool not only for policy makers and scientists, but also for extension specialists, farmers, and even consumers. Therefore, it is a matter of urgency to understand the current status of SIS in individual countries in the region, and to formulate an appropriate regional SIS scheme for the entire would-be users in the ASPAC.
