Abstract
Gully erosion is the major environmental problem threating huge area of agricultural lands in south Ethiopia, particularly. The present study aimed at evaluating demonstrates gully treatment methods for gully rehabilitation in Kamba, South Ethiopia. On farm filed experiments, key informant interview and focus group discussion were used to collect and analyze experimental data. The result of this study indicates that integration of check dame with Elephant grass have significant effect on gully rehabilitation. This integration was reduced gully depth, slope gradient, gully volume and soil loss. Slope of gully bed was reduced by 60%, 46% 37% respective years. Similarly gully depth reduced by 2.54m, 1.72m and 1.456m while gully volume was reduced by 37.44m3, 8.81m3 and 4.32m3 due to check dam as the same order of slope changes. Data such as sediment deposition and biomass production were collected, to investigate their effectiveness in reducing soil erosion and biomass production. Over a period of two years practices caused measurable gully morphology resulted soil calculated was 248.41kg of soil were deposited in 12.76m2 area. According to Focus group discussion farmers viewed these gully rehabilitation measures was positively, apart from the high labour, input materials and technical requirements of stone check dam. Based on the results the study concluded that check dam integrated with Elephant grass in the gully bed have positive effective rehabilitate gully erosion in the study area. Therefore, farmers should use gully rehabilitation techniques to preserve their land.
