Study of relationship between man and its environment. The different patterns of landuse depend on the physical aspect of the watershed classification areas. For instance, most of people have grown "Miang" (Camelia Sinensis) on the mountain of the first and second watershed classifications. The people of the third watershed class have to grow rainfed crop on the upland area. While in the fourth and fifth watershed classes, most of villagers have grown paddy rice and some cash crops. Because of a small average land holding, the farmers were forced to maximize utilization from their land by practicing intensive landuse especially in the fifth watershed class. The shortage of arable land was the major problem of land resources. Most of the farmers agreed with the proposed idea that the government should allocate empty land and deforested area to the landless farmers. They also accepted the concept of landuse zoning. The utilization of land resources was significantly related to the available water supplies. The shortage of water resources alway occurs in the third watershed class i.e.,the upland area. The farmers in the fifth watershed class have managed a good system of water resource utilization since the old days. They set the organization of farmers to allocate water among their member and co-operated in maintenance the water supplies. At present, there are irrigation projects which supply water to the most part of area in the fifth watershed class. As regards other watershed classes there are various small scale of local irrigations scattering in area with better management by the villagers themselves.
