This paper investigates opportunities to combat desertification utilizing the medicinal plant licorice (Glycyrrhiza uralensis). Licorice natively lives in arid region such as Mongolia and China, although the numbers of individuals are decreasing due to excessive harvesting, overgrazing and decreasing groundwater levels caused by unstable rainfall, ultimately leading to increase desertification. Due to these facts, licorice was picked up as “precious genetic resource” at COP 10 (Conference of the Parties, Convention on Biological Diversity) because there is a supply shortage of licorice as herbal medicine. Therefore, there may be anti-desertification opportunities through the development of a planting method for licorice in arid ground, especially those areas of extreme desertification where other crops are not grown. Furthermore, if the method is given to local people, it will be value-added greening. This means that the method will contribute to anti-desertification while also decreasing the supply shortage of licorice and stimulating the local economy. As the fundamental research to accomplish these purposes, the relationships between soil water environment, soil saline environment and growth of licorice should be determined. This paper examines the function of “greening soil material” on the growth of licorice in a cultivation experiment. And the evaluation method about relationships between soil water environments, soil saline environment, especially calcium concentration and the growth of licorice were examined by using greening soil material and imitating arid ground..
5. Development of technique which can restrain the progress of desertification sustainably and voluntary is taken place by using valuable herbal plant licorice (Glycyrrhiza uralensis). Firstly, prehension about geo-environment included weather condition around the study areas is needed to succeed the technique. This paper indicates the results of geo-environmental survey were held in the arid area where licorice lives natively and doesn’t live. And this paper also shows the consideration about difference between habitat and non-habitat of licorice, and relationships between physical properties and chemical properties in the ground. The experimental results are concluded that 1) The arid ground in Bogd soum and Baatsagaan soum in Bayanhongor province, Mongolia, the ground was heterogeneous whose grain size properties are between sand and silt within the depth of 1 ~ 2 m. 2) Water content in the ground which licorice could be lived was at least more than 5 %, and keeping groundwater level and ground moisture could be important for bringing up seedlings of licorice. 3) The silty layers has relatively higher available moisture than the sandy layers, and calcium carbonate (CaCO3) accumulated in the silty layers, so that they had higher pH and EC values than sandy layer..

In order to accomplish these purposes, in-situ investigation was conducted to grasp soil condition of arid land where licorice known for remarkable medicinal plant lives naturally. And based on the results of the investigation and cultural experiment in Japan, fundamental consideration for greening by cultivating licorice and using “pipe-shaped pot” was conducted. This research was concluded that 1) Wild licorice can live around 10 % of volumetric water content of ground within the depth of 1 m, 2) Wild licorice can live low nutrition environment, 3) From the results of cultivation experiment in Japan, young licorice grew well under much moisture and nutrition in the ground, and 4) From the results of application for greening by using pipe-cultivation, it was suggested that young licorice can grow well and height of 10 cm pipe was enough to support initial growth..

We developed pipe-shaped Greening Soil Materials (GSM), made of sand and compost which can be taken from Mongolian arid region. It can be made and installed in the ground easily and inexpensively. Moreover, it is characterized to have high water and nutrient retention capacity to support growing plants. Therefore, it is identified as simple self-watering system without any water supply. As the suitable plant for greening, we selected licorice (Glycyrrhiza uralensis) which is one of the most valuable medicinal plants growing in Mongolian and Chinese arid region. However, supply shortage and land degradation due to natural and human factors occur recently. Therefore, planting licorice by using GSM could be sustainable and high value-added greening. In this paper, in order to grasp the effects and functions of GSM, field cultural experiments were conducted in non-habitat of licorice without any irrigation except before setting for 4 or 9 months. The results are as follows; 1) Larger volume of GSMs could keep the survival rate of licorice higher than smaller types. 2) The conditions setting GSMs vertically and horizontally were same effects for survival rate of licorice. 3) Artificial compost (UB) could keep the survival rate of licorice about 1.4 times higher than animal fertilizer (LC). 4) At the range of these experimental conditions, 20 – 25 g/pot of CaCO3 could keep the highest survival rate..

These problems can be solved by geo-environmental viewpoint. Coping with greening, this research paid attention to the medicinal plant licorice. It lives in semi-arid lands and its root which contains active ingredient is highly demanded. Value added greening which brings up licorice in arid land enables sustainable development to be succeeded. This research was conducted in-situ investigation to grasp soil water and nutritive condition of arid land. In addition, from the result of those investigation and cultivation experiment in Japan, as the fundamental consideration for value-added greening, this research conducted several cultivation experiments to promote initial cultivation of licorice and take root more quickly in the ground simulated sand by using pipe-shaped pot. This research was concluded that 1) Wild licorice in semi-arid land lives under law water and nutrition in the ground by growing its root to catch the groundwater and nutrition as much.2) Young licorice could not grow better in Japan by using only silica sand, which is similar to Mongolian soil than the individuals cultivated by potting compost.3)Using pipe-shaped pot is effective for greening because licorice grows bigger and longer than the individuals cultivated by simulated ground and keep growing their root into the simulated ground..

has been used in about 70% herbal medicine. Japan imported 100% of Kanzo mainly from China so that
cultivation in Japan. This paper presents the influences of soil water, types of soil and liquid nutrient on
growth of Kanzo cultivated by using pipe-shaped pot. The experimental results indicate that (1) the soil in
alkaline condition is suitable for cultivating Kanzo, (2) when concentration of fertilizer is low,
evapo-transpiration velocity becomes greater, (3) Kanzo cultivated using the decomposed granite soil and
1/8th concentration of standard liquid fertilizer is the highest content of Glycyrrhizin (GL). On the other
hand, the root length of Kanzo with high GL content was shorter than that of other conditions..
