Soil Erosion Mapping in Singhanhalli-Bogur Microwatershed in Northern Transition Zone of Karnataka Using Universal Soil Loss Equation and Geographic Information Systems
Journal Title: International Journal of Interdisciplinary and Multidisciplinary Studies (IJIMS) - Year 2014, Vol 1, Issue 10
Abstract
Soil erosion which occurs at spatially varying rates is a widespread threat to sustainable resource management at watershed scale. Thus estimation of soil loss and identification of critical area for implementation of best management practices is central to a successful soil conservation programme. The present study was conducted to assess soil erosion using USLE and suggests possible intervention strategies to address soil loss in Singhanhalli-Bogur Microwatershed of Dharwad District in northern transition zone of Karnataka. The average annual soil loss was 27 tons ha-1yr-1. About 574 ha of the study area was under slight erosion, 118 ha under moderate erosion and 53 ha under severe erosion. The soil loss under different land uses ranged from 7 tons ha-1yr-1 under forest to 40 tons ha-1yr-1 under agriculture. The soil loss under plantation and open scrub land uses were 8 and 26 tons ha-1yr-1 respectively. Major causes of soil erosion were cultivation without proper soil and water conservation measures in area not suitable for crops, denuded areas without vegetation, cultivated fallow on moderate slopes, degraded forests/pastures on steep slopes and poorly managed forest cover. Appropriate soil conservation and land management techniques for the different soil erosion classes were suggested.
