Mapping Of Erosion Hazard Levels In The Padang Watershed
Erosion Hazard Map in the Padang Watershed: Examining Threats and Preventive Efforts
Introduction
The Padang watershed, located in the DAS Padang region, has been identified as a top priority area due to its serious threat of soil erosion. According to the Minister of Forestry Decree No. 328/Menhut-II/2009, the Padang watershed is facing a significant risk of soil erosion, which is exacerbated by the conversion of forest land into agricultural land. This change has led to an imbalance in the ecosystem and has contributed to the increase in soil erosion. The main factors that trigger erosion in this region include open land, high rainfall, and steep slopes.
Background
Research conducted in 2014 by Triskin Puji. A. S. titled "Mapping Erosion Hazard Level in Padang Watershed" aimed to map the level of danger of erosion and sedimentation in the Padang watershed. The study was conducted in Serdang Bedagai, Tebing Tinggi, and Simalungun using the Purposive Sampling and USLE (Universal Soil Loss Equation) method to predict the level of soil erosion. The results of the study provided valuable insights into the level of erosion danger in the Padang watershed and highlighted the need for preventive and rehabilitation efforts to mitigate the impact of soil erosion.
Erosion Hazard Levels in the Padang Watershed
The results of the study showed that the level of erosion danger in the Padang watershed was divided into five categories:
Medium Erosion (41.58%)
Regions with a medium erosion hazard level are a serious threat because they have the potential to increase into severe erosion in the future. Prevention and rehabilitation efforts are very important to do in this area. Medium erosion regions require immediate attention and management strategies to prevent an increase in the level of erosion in the future.
Light Erosion (34.70%)
Although classified as light, this region still needs attention and management strategy to prevent an increase in the level of erosion in the future. Light erosion regions require regular monitoring and maintenance to prevent damage and ensure environmental sustainability.
Severe Erosion (13.47%)
The level of severe erosion indicates significant soil damage and requires immediate treatment to prevent more severe impacts. Severe erosion regions require intensive rehabilitation and recovery efforts to restore the ecosystem and prevent further damage.
Very Light Erosion (5.50%)
Region with a very mild erosion level needs to be monitored and maintained to remain avoiding damage. Very light erosion regions require regular monitoring and maintenance to prevent damage and ensure environmental sustainability.
Very Severe Erosion (4.75%)
Region with a very heavy erosion level requires intensive rehabilitation and recovery efforts. Very severe erosion regions require immediate attention and management strategies to prevent an increase in the level of erosion in the future.
Strategies to Overcome Erosion in the Padang Watershed
The erosion hazard map provides a real picture of the condition of the Padang watershed and is an important reference in efforts to prevent and overcome soil erosion. Some strategies that can be applied to overcome erosion in the Padang watershed include:
Forest Rehabilitation
Returns of forest function through trees replanting programs in critical and degraded areas can help control soil erosion and improve environmental quality. Forest rehabilitation is an essential strategy to restore the ecosystem and prevent further damage.
Increasing Land Governance
The application of sustainable agricultural systems, terraces, and soil conservation can reduce soil erosion and increase land productivity. Increasing land governance is crucial to ensure the effective management of land resources and prevent soil erosion.
Increasing Public Awareness
Socialization and education to the public about the importance of environmental preservation and the impact of land erosion is very important to build community awareness and participation in efforts to prevent erosion. Increasing public awareness is essential to ensure the involvement of local communities in efforts to prevent and overcome soil erosion.
Monitoring and Evaluation
Periodic monitoring of the level of soil erosion and the implementation of prevention strategies is very important to ensure the effectiveness of the efforts made. Monitoring and evaluation are essential to assess the impact of preventive and rehabilitation efforts and make necessary adjustments to ensure environmental sustainability.
Conclusion
By paying attention to the erosion hazard map and applying the right prevention strategy, we can save the Padang watershed from the threat of damage and ensure environmental sustainability for future generations. The erosion hazard map provides a valuable tool for policymakers, researchers, and local communities to understand the level of erosion danger in the Padang watershed and develop effective strategies to prevent and overcome soil erosion.
