Relationship of Erosion and Farmer Income in Ayung Watershed, Bali, Indonesia

Made Sri Sumarniasih


Ayung Watershed to be research location is the longest watershed in Bali, Indonesia, which have suffered very heavy the land degradation. The purpose of the research are: (1) Predicting the erosion, (2) Analyze the farmers income, and (3)  in the Ayung watershed and its relation to the level of erosion. Analysis of the data using the USLE method to predict the rate of erosion, income  analysis to analyze the farmers income that source from farming and non farming, and the descriptive-qualitative analysis to explain the results of the calculation of erosion and farmers' income. The results of research showed that the erosion in the Ayung watershed from very light  to very heavy with  ranged from 0,98 to 1717,12 tons /ha/year, while erosion is allowed to range from 22,60 to 57,00 tons/ha/year, the simulation results decreased to very light erosion ranged 0,98-50,85tons/ha/year; Income of farmers in the upper reaches of the Ayung watershed is the highest than the income of farmers in the central and downstream part of the Ayung watershed, but was followed by a high erosion rate. While the income of farmers in the central dan downstream part of the Ayung watershed lower than the income of farmers in the upper of the Ayung watershed, but was  followed by a lower erosion rate. However, based on Spearman rank correlation analysis, there is no relationship between the level of erosion and farmers' income. This  is mean the erosion rate decreases because of the efforts of land and water conservation will not be followed by a decline in the income of farmers.
