The Deccan Plateau: Volcanic Terrain Influencing Monsoon Rainfall and Agriculture
德干高原：火山地貌影响季风降水与农业格局
-
The Deccan Plateau covers much of peninsular India and formed from massive volcanic eruptions 66 million years ago.
-
Its basalt bedrock weathers slowly, creating nutrient-rich black cotton soils ideal for cotton and sorghum cultivation.
-
Western Ghats intercept monsoon winds, causing heavy rainfall on the windward side and aridity eastward across the plateau.
-
Rivers like the Krishna and Godavari flow eastward, carving broad valleys through layered lava flows.
-
Groundwater storage is high in fractured basalt, supporting wells even during prolonged dry seasons.
-
Laterite caps on elevated ridges indicate past tropical weathering under warmer, wetter climates.
-
Urban expansion around cities like Hyderabad stresses aquifers faster than natural recharge can replenish them.
-
Terraced farming on gentle slopes reduces erosion while conserving moisture in semi-arid sub-regions.
-
Solar radiation intensity here supports large-scale photovoltaic farms built on marginal agricultural land.
-
Soil degradation from over-cropping and declining organic matter threatens long-term food security across the plateau.
