This issue becomes quite serious due to illegal logging and agricultural land conversion, mostly for maize fields as one of Gorontalo’s top commodities. As an attempt to analyze the problems, this study is undergone through field observation and documentation. This study covers aspects of socio-biogeophysical characteristics of the Alo drainage basin and analyzes the level of soil surface erosion and tolerable erosion rate. 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 is 98.79 hectares wide. This suggests that the inappropriate use of land is more likely to increase the erosion hazard rate. ## Keywords - Erosion - Environmental science - Drainage basin - Hazard - Hydrology (agriculture) - Drainage - Hectare - Structural basin - Rainwater harvesting - Water resource management - Geology - Agriculture - Geography - Geotechnical engineering - Geomorphology - Biology - Chemistry - Archaeology - Cartography - Organic chemistry - Ecology --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
