The ravines of Chambal have probably originated from tectonic activity and have till date shown no obvious relation to climate, but continued deforestation exposes the nutrient deficient soil, which exacerbates ravine expansion. Extreme climatic events in such a scenario can speed up erosion and prompt a disaster.
Chambal ravine formation significantly increases soil loss from agricultural lands and severely impacts agricultural productivity. A review of ephemeral gully erosion and spreading rates of the ravenous tracks of Lower Chambal Valley using geospatial tools shows that both the ravenous and the marginal lands have increased during the last 15 years. A slow natural disaster- ravine erosion is an obvious threat to the inhabitants of the region. Conventionally, ravine formation, classified as soil erosion, does not feature as a natural...
