To implement in the project "Preparation of the Soil Atlas of Asia through the update of national soil maps and National Soil Information Systems for AFACI Countries” funded by Asian Food and Agriculture Cooperation Initiative (AFACI), Rural Development Administration (RDA), Republic of Korea, from March 23 to April 3, 2020, FAO-AFACI co-organized the project launch meeting and an online training course on digital mapping of salt-affected soils. There were six researchers of SFRI participated in this training.

Influenced by the Covid 19 epidemic, the meeting of the AFACI project took place on the Zoom virtual platform on March 23, 2020. The online meeting provided an opportunity for all project participants to receive additional information about the entire project, to introduce country-specific current activities, to clarify further if there is a problem that need to be exchanged and interact with other countries in the project.

In order for each country to develop salinity maps, FAO conducted training with a demo data set prepared by FAO experts. The input data requirements for soil mapping required includes soil properties (EC, ESP, pH), and spatial predictors of salt-affected soils (soil types, climate, topography, geology, satellite imagery, etc.) The spatial datasets were processed and synchronized, then used to computed a relationship with the soil properties.   

After the training, depending on the specific conditions, each country will develop appropriate data sets to make soil salinity maps, combine with maps of other countries and create a database to include into the National Soil Information System.
