COMMENTS :
General description: The Watershed Classification describes the potential degradation risk when cleared of the original vegetation cover;
The item 'value' is encoded as follows:
1=  Protection Forest.   
Areas with very steep slopes and rugged landforms, commonly uplands and headwater areas. Critical areas for water and soil resources management. Recommended land use: as a rule, these areas should be under permanent forest cover. Other existing land uses based on traditional rights and practices should be considered carefully with regard to their impact on water and soil conservation.
2 = Commercial Forest.  
Areas with steep slopes, usually at higher elevation. Landforms are in general less susceptible to water and soil degradation than under WSC Class 1. Recommended land use: forest (conservation and production forests), agro-forestry and grazing, if accompanied by strict conservation measures.
3 = Agro-Forestry.      
Areas with moderate to steep slopes and less erosive landforms. Includes uplands and foot zones of slopes. Wider range of land use tolerable than in WSC Classes 1 and 2 from point of view of water and soil conservation. May be used for commercial forest, grazing and combinations of trees and agricultural crops, if appropriate conservation measures are applied. 
4 = Upland Farming.    
Gently sloping lands. Moderate need for water and soil conservation depending on local conditions. Wide range of land use possible from point of view of water and soil conservation: agriculture and forest.
5 = Lowland Farming.   
Gently sloping land and flat areas. Suitable for a wide range of land use from point of view of water and soil conservation: paddy rice, other agricultural uses and forest.
WSC Equation:     WSC = a + (b * slope) + (c * elevation) + (d * landform)
Factor Units:     slope: percent, elevation: decameters, landform: classes 1-21
Parameters:       a = 1.709, b = -0.035, c = -0.002, d = 0.163
