4.3 Analysis of Farmer Income

Farming conditions are represented by the average income of farmers sampled in each part of the watershed upstream, midstream, downstream, when linked with the level of erosion in the watershed of each section, it turns out the highest income of farmers in the Ayung watershed upstream section followed by erosion rate from mild to very severe 1.04 to 724.86 t ha-1 yr- 1. The middle and downstream watershed erosion 32 Ayung very mild to very severe, the center of the erosion 0.50 to 221.97 t ha-1 yr-1 and the downstream erosion from 0.22 to 31.80 t ha-1 yr-1.

H 0 = be accepted Rs =coefisien correlasi of Rank Spearman = 0,25 R-table 5, n=3 =1,00 Differences in income in the upstream, midstream and downstream are caused by differences in the type of farming, the dominant upstream while the orange groves in the middle and lower reaches of the Ayung watershed is in the form of paddy rice farm. Revenues in the upstream economically beneficial but environmentally vulnerable to erosion, due to citrus crops in the planting of traditional terrace monokoultur without amplifier patio plants. 33 The income of farmers in the middle and lower reaches of the watershed is lower, due to the people in the middle and downstream land managed acreage has more narrow around 30-36 acres. Farmers can not change the land use to land uses for citrus crops, because it is a wetland or rice field, with a Subak system where the member of Subak obey to rule awig-awig in the Subak. The relationship of the farmers income and erosion rates were then analyzed using Spearman Rank. The analysis showed that high income is not always followed by a high erosion or otherwise. This is caused by high revenues for major crops are citrus crop whose price is determined by the market.
