SFB 564: B1.3 - Water conservation scenario development at the regional level innovative mapping techniques
Project
Project code: DFG SFB 564

Purpose of research: Applied research
opulation increase especial in the highlands of northern Thailand, reforestation, in-creasing wealth gradient between highland and lowland as well as the commercialisation of agriculture is responsible for the extreme competition for land and water re-sources. For this reason new approaches are urgently required, which intensify the use of land and water on the one hand, and which are ecologically and economically acceptable. The investigations of the second phase showed, that there are many agriculture systems in the highlands of northern Thailand. All of them can clearly be distinguished by their ecological and economical sustainability. A basic requirement of agricultural land use planning is the knowledge about the distribution pattern of soils and their site properties. Until now, there is not any soil map or soil information system for the highlands available, which could be used for a serious land use planning. For this reason intensive soil and petrographic mapping was carried out for three different petrographic areas. This soil knowledge gained during the second phase will now be used to calibrate radiometric data of northern Thailand to generate a digital soil map. In a next step the soil physical properties will be assigned to specific soils by transfer functions. Participative soil mapping, carried out in cooperation with A1.3, will help to find the boundaries of soil physical properties and to validate the soil map. Finally, the soil map information will be a tool which can be used for different kinds of models. In cooperation with C4.1; using the WaNulCAS model; efficient and adapted land use strategies will be developed and assigned to suitable areas. In the past many land development projects failed, because of their top down nature. For this reason a participatory land suitability analysis (PALSA), in cooperation with A1.3, C4.1 and G1.2, will be applied to assure that the developed land use strategies will be acceptable for the local people.
