Abstract

Damages to the land resources, mainly those happening on drainage basin at Alo, Gorontalo occur in consequence of degradation of the ground surface layer as hit by raindrops and rainwater flow that carry soil surface. This issue becomes quite serious due to illegal logging and agricultural land conversion, mostly for maize fields as one of Gorontalo’s top commodities. The purpose of this tudy is to determine the level of erosion hazard in the Limboto Lake catchment area. In order to achieve these objectives two methods are used namely the field survey and documentation. The research material used includes of socio-biogeophysical characteristics of Alo drainage basin and analyzes the level of soil surface erosion. The result shows that 98.75 percent of erosion hazard is classified into low to moderate, covering approximately 6,874.721 hectares. Meanwhile, 1.25 percent of the high to extreme level of erosion hazard are 98.79 hectares wide. This suggests that inappropriate use of land is more likely to increase the erosion hazard rate.
