Analysis Of Changes In Land Cover Of The Sei Snake Watershed
Introduction
The Sei Snake Watershed (DAS) is a vital region that plays a crucial role in accommodating, storing, and flowing water that comes from rainfall naturally. As a vital component of the ecosystem, the Sei Snake Watershed has an important function in maintaining the balance of nature and supporting the livelihoods of local communities. However, the increasing demand for land and resources has led to significant changes in land cover, which can have far-reaching consequences on the environment and the local ecosystem.
Background
The Sei Snake Watershed is an area that unites the main river and the river children. The region's topographic separation and boundaries in the sea stretch to the waters that are still affected by activities on the mainland. This study aims to analyze the land cover class in the Sei Snake watershed and identify changes in land cover that occurred within ten years, from 2007 to 2017.
Methodology
In this study, the authors used the Landsat 7 TM image from 2007 and Landsat 8 oil from 2017. The classification method used was the maximum opportunity method (maximum likelififier) to identify and classify the existing land cover. The use of satellite imagery and remote sensing techniques allows for the accurate identification and classification of land cover classes, providing valuable insights into the changes that have occurred in the Sei Snake watershed.
Results
From the results of the study, found nine classes of land cover in the Sei Snake watershed, which consisted of water, forest, vacant land, mangroves, settlements, plantations, rice fields, shrubs, and ponds. The classification of land cover classes is essential in understanding the changes that have occurred in the Sei Snake watershed and identifying the areas that require conservation efforts.
Changes in Land Cover
Based on the data obtained, some significant changes occur in the land cover between 2007 and 2017. The following are the details of changes in land cover area:
- Forest: decreased by 3.74%
- Mangrove: decreased by 0.14%
- Shrub: decreased by 6.95%
- Tambak: decreased by 2.62%
- Water Agency: increased by 0.1%
- Empty land: increased by 7.24%
- Settlement: increased by 4.32%
- Plantation: increased by 1.07%
- Rice fields: increased by 1.16%
Discussion
Changes in land cover that occurred in the Sei Snake watershed showed a significant tendency. The decrease in forest and shrubs can be associated with deforestation activities that may be caused by land clearing for settlements and plantations. This can cause negative impacts on local ecosystems, such as loss of habitat and decreased biodiversity.
On the other hand, the increase in areas of vacant land, settlements, and plantations reflects population growth and increasing the need for land for various interests, such as agriculture and housing. Although there is an increase in the water body, this does not necessarily show the recovery of ecosystems, but it could be a result of inefficient water management or changes in rain patterns.
Conclusion
This study provides a clear picture of changes in land cover in the Sei Snake watershed for a decade. This data is very important for the management of natural resources and sustainable spatial planning. Better conservation steps are needed so that the negative impact of land cover changes can be minimized, and so that the function of the watershed as a reservoir and water regulator is maintained.
Recommendations
Based on the findings of this study, the following recommendations are made:
- Conservation efforts: Efforts should be made to conserve the remaining forest and shrub areas, which are essential for maintaining biodiversity and ecosystem balance.
- Sustainable land use planning: Land use planning should be done in a sustainable manner, taking into account the needs of local communities and the environment.
- Water management: Efficient water management practices should be implemented to minimize the impact of changes in land cover on water resources.
Future Research Directions
This study provides a valuable insight into the changes that have occurred in the Sei Snake watershed over the past decade. However, further research is needed to understand the long-term impacts of these changes and to identify effective strategies for mitigating the negative effects of land cover changes.
Limitations of the Study
This study has several limitations, including:
- Data availability: The availability of data for the study period was limited, which may have affected the accuracy of the results.
- Methodological limitations: The use of remote sensing techniques and satellite imagery may have limitations in terms of accuracy and resolution.
Conclusion
In conclusion, this study provides a comprehensive analysis of changes in land cover in the Sei Snake watershed over the past decade. The findings of this study highlight the need for conservation efforts and sustainable land use planning to minimize the negative impacts of land cover changes on the environment and local ecosystems.
