Degraded lands in Vidarbha region of Maharashtra were assessed using remote sensing technique. District wise land degradation maps were generated on 1:25,0000 scale through visual interpretation of lRS 1A data supported by limited ground survey. It was observed that degraded lands occupy nearly 2.1 million ha or 21.5 per cent of the total geographical area. The analysis of district wise land degradation statistics indicate that. Yavatmal and Akola districts are graded as having most problematic lands in the region. Nagpur, Amravati, Buldana and Wardha districts are categorised as moderately problematic, whereas Gadchiroli, Chandrapur and Bhandara are districts having least problem of degradation. Among the major land forms, the largest degraded area is associated with undifferentiated plain accounting for 1.1 million ha or 12 per cent of the total area of region, which is mostly under cultivation. It thus follows that problem of degradation is more rampant in agricultural land than forest/waste lands.
