| Biophysical | Socioeconomics |
A: Plateau; undulating; well-drained sandier soils; shallow tributary streams; semi-deciduous vegetation | Small-scale, extensive dryland agriculture/livestock and exploitations of vegetation; partly conservation | Dryland ecosystem fragmentation (moderate to high); Reduction of vegetation density/diversity (moderate); Increased soil dryness (moderate to high); Soil nutrient depletion in agroecosystems (moderate to high); Erosion by wind (moderate) | High intensity forest exploitation; dryland farming on small farm plots; Extensive grazing on natural pastures; Very low to low density of population villages; partly conservation | |
B: Gently sloping (long slopes) partially steep slope land; well- to moderately drained sandy loam to loamy sand soils, locally lithic; deep tributary streams; semi-deciduous vegetation | Small-scale, extensive dryland agriculture/livestock and exploitations of vegetation | Dryland ecosystem fragmentation (moderate); Reduced vegetation density/diversity (high); Increased soil nutrient depletion in agroecosystems (moderate to high); Reduced thickness of the uppermost soil horizon (moderate); Erosion by water (moderate to high); Increased dryness (moderate to high) | Forest exploitation (low intensity); dryland farming on small farm plots; Extensive grazing on natural pastures; Low density of population villages (sparse villages); partly conservation | |
C: Plains and valley bottom of the great river; clay-sand sediments of surface runoff; wetlands and lakes; main rivers | Small-scale, extensive, manual-watered agriculture/livestock; partly conservation | Siltation of lake and wetland ecosystems (moderate); Soil compaction (moderate); Salinization (moderate); Flooding (moderate) | Forest exploitation (very low intensity); dryland/wetland farming on small farm plots; Low partly very high density of population villages; partly conservation | |
