Study of Erosion Hazard Level (TBE) in the Use of Agroforestry Land in the Sub-Lauber Watershed (Upstream Watershed Area)

Erosion is a significant environmental problem that affects agricultural areas and agroforestry worldwide. The transition of forest land into agricultural land in the upstream area of the watershed, especially in the sub-watershed, has caused a significant increase in erosion. This process not only threatens the sustainability of agroforestry itself but also has the potential to damage the upstream river ecosystem, which is important for the sustainability of water resources and the lives of the surrounding community. This study aims to understand how much influence the use of agroforestry land on the rate of soil erosion.

Research Background

The transition of forest land into agricultural land in the upstream area of the watershed, especially in the sub-watershed, has caused a significant increase in erosion. This process not only threatens the sustainability of agroforestry itself but also has the potential to damage the upstream river ecosystem, which is important for the sustainability of water resources and the lives of the surrounding community. The use of agroforestry land has been increasing in recent years, and it is essential to understand the impact of this land use on soil erosion.

Agroforestry is a land-use system that combines trees with crops and/or livestock. It is a sustainable way of managing land, as it provides multiple benefits, including soil conservation, biodiversity, and climate regulation. However, the transition of forest land into agroforestry land can lead to soil erosion, as the removal of trees can expose the soil to erosion. The rate of soil erosion depends on various factors, including soil type, land slope, rainfall, and land management practices.

Research Methods

This study uses two methods to measure the level of erosion, namely the Universal Soil Loss Equation (USLE) and the Small Square method. A total of ten sub-watersheds are used as samples for data collection. Some observed parameters include soil types, effective soil depth, soil permeability, C-organic content, soil texture, soil structure, land slope, and rainfall.

The USLE method is a widely used method for estimating soil erosion. It takes into account various factors, including rainfall, soil type, land slope, and land management practices. The Small Square method is a more conservative method that estimates soil erosion based on the area of the land and the amount of rainfall.

Research Results

From this study, it was found that the transition of forest land functions into agroforestry affects the increase in the number of erosion that occurs. Based on the USLE method, the average erosion that occurs is 184,474 tons/ha/year. Meanwhile, according to the Small Square method, the average erosion was recorded at 20,418 tons/ha/year, which was smaller than the results of the USLE method. This difference shows that each method has a different approach in estimating the level of erosion that occurs.

The results of this study emphasize the importance of considering the method used in measuring soil erosion. The USLE method that gives a higher number may be more sensitive to environmental factors such as slope and rainfall, while the Small Square method can provide more conservative estimates.

Analysis and Explanation

The results obtained from this study highlighted the importance of considering the method used in measuring soil erosion. The USLE method that gives a higher number may be more sensitive to environmental factors such as slope and rainfall, while the Small Square method can provide more conservative estimates.

In addition, other factors such as improper land management and climate change also contribute to the rate of erosion. Therefore, a comprehensive understanding of the dynamics of land use and conservation management is very important to prevent further damage to the ecosystem.

Conclusion

This study provides valuable insight into the dangers of erosion in the agroforestry area in the sub-watershed. By knowing the level of erosion, appropriate prevention steps can be taken to maintain the sustainability of agricultural land and the surrounding ecosystem. This study also highlighted the need for better land use planning and natural resource management strategies to reduce the negative impacts of erosion in the area.

Through wiser management, it is hoped that the upstream area of the watershed can be maintained as a vital resource for the community and the environment. The results of this study can be used as a reference for policymakers, land managers, and researchers to develop strategies for reducing soil erosion and maintaining the sustainability of agroforestry land.

Recommendations

Based on the results of this study, the following recommendations are made:

Conduct further research: Further research is needed to understand the dynamics of land use and conservation management in the sub-watershed.
Develop better land use planning: Better land use planning is needed to reduce the negative impacts of erosion in the area.

Limitations of the Study

This study has several limitations, including:

Limited sample size: The sample size of this study is limited to ten sub-watersheds.
Methodological limitations: The USLE and Small Square methods have different approaches in estimating soil erosion, which may lead to different results.
Data limitations: The data used in this study may not be representative of the entire sub-watershed.

Despite these limitations, this study provides valuable insights into the dangers of erosion in the agroforestry area in the sub-watershed.
