Mapping Changes in Land Closure in the Dolok Surungan Wildlife Reserve Forest: A Study on Deforestation and Community Perception

Introduction

Indonesia's forests have been experiencing a significant decline in quality over the years, with an increase in changes in forest land use into other areas. This has led to a pressing need for land and forest rehabilitation efforts to overcome these issues. One crucial step in this rehabilitation process is the identification of land cover changes. This study aims to understand changes in land use in the Dolok Surungan Wildlife Reserve and to explore the perception of the community around the forest related to deforestation that has occurred. Additionally, this study also shows how the Geographic Information System (GIS) can be used to evaluate the form of deforestation.

Background

Indonesia is home to some of the most biodiverse forests in the world, with the Dolok Surungan Wildlife Reserve being one of the most significant protected areas. However, despite its importance, the reserve has been facing significant threats from deforestation and land degradation. The increasing demand for land for agriculture, urbanization, and other human activities has led to widespread deforestation, resulting in the loss of biodiversity and ecosystem services.

Methodology

This study utilized the Landsat ETM satellite image obtained in 2003, 2006, and 2009 using the digitization method on the screen. The analysis was carried out to identify changes in land cover over the study period. The results showed that between 2003 and 2009, there was a significant increase in land cover changes. From the Analysis of Landsat ETM imagery, it was found that primary forests decreased by 2,038.92 ha or 47.77%. Meanwhile, secondary forests increased by 1,428.81 Ha (33.48%), rubber plantations increased by 428.74 ha (10.05%), and oil palm plantations increased by 276.34 ha (6.48%). On the other hand, unreged land has decreased by 94.97 Ha (2.23%).

Results

The results of this study showed that there was a significant increase in land cover changes in the Dolok Surungan Wildlife Reserve between 2003 and 2009. The decrease in primary forests was significant, with a loss of 2,038.92 ha or 47.77%. This was accompanied by an increase in secondary forests, rubber plantations, and oil palm plantations. The increase in plantation land use was likely driven by the demand for agricultural products and the economic benefits associated with land conversion.

Community Perception

The perception of the community around the Dolok Surungan Wildlife Reserve shows that they tend to prefer to change forest land into plantation land to improve their economy, rather than utilizing the potential of the forest itself. This reflects a big challenge in maintaining a balance between community economic needs and environmental preservation. The community's perception of the forest as a resource for economic gain rather than a valuable ecosystem is a significant barrier to conservation efforts.

Geographic Information System (GIS)

The Geographic Information System (GIS) plays an important role in mapping this change. Through this technology, we can identify and analyze spatial data related to deforestation, making it easier to plan and manage forest resources in a sustainable manner. GIS can be used to analyze the spatial distribution of land cover changes, identify areas of high deforestation risk, and develop strategies for forest conservation.

Conclusion

Mapping changes in land closure in the Dolok Surungan Wildlife Reserve not only a scientific study, but also a call for actions for all parties. Cooperation is needed between the government, researchers, and the community to create sustainable solutions in dealing with the problem of deforestation. By understanding and analyzing existing data, we can design more effective policies to protect our forests, maintain biodiversity, and support the lives of people who depend on forest resources.

Recommendations

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

  1. Community engagement: Engage with the local community to raise awareness about the importance of forest conservation and the impact of deforestation on their livelihoods.
  2. GIS-based planning: Use GIS to develop a comprehensive plan for forest conservation and management, taking into account the spatial distribution of land cover changes and the needs of the local community.
  3. Sustainable land use: Promote sustainable land use practices, such as agroforestry and permaculture, to reduce the pressure on forests and maintain ecosystem services.
  4. Policy development: Develop policies that support forest conservation and sustainable land use, and ensure that these policies are implemented effectively.

Future Research Directions

This study highlights the need for further research on the impact of deforestation on forest ecosystems and the local community. Future research should focus on:

  1. Long-term monitoring: Conduct long-term monitoring of land cover changes to understand the dynamics of deforestation and forest regeneration.
  2. Community-based conservation: Develop community-based conservation initiatives that engage local communities in forest conservation and management.
  3. GIS-based modeling: Use GIS-based modeling to predict the impact of deforestation on forest ecosystems and develop strategies for forest conservation.

By understanding the changes in land closure in the Dolok Surungan Wildlife Reserve, we can develop effective strategies for forest conservation and sustainable land use. This study highlights the importance of community engagement, GIS-based planning, and sustainable land use practices in maintaining the integrity of forest ecosystems and supporting the livelihoods of local communities.
Q&A: Mapping Changes in Land Closure in the Dolok Surungan Wildlife Reserve Forest

Q: What is the significance of the Dolok Surungan Wildlife Reserve Forest?

A: The Dolok Surungan Wildlife Reserve Forest is one of the most significant protected areas in Indonesia, home to a vast array of biodiversity and ecosystem services. It is a critical habitat for many endangered species and plays a vital role in maintaining the health of the surrounding ecosystem.

Q: What are the main findings of this study?

A: The study found that between 2003 and 2009, there was a significant increase in land cover changes in the Dolok Surungan Wildlife Reserve Forest. Primary forests decreased by 2,038.92 ha or 47.77%, while secondary forests increased by 1,428.81 Ha (33.48%). Rubber plantations and oil palm plantations also increased significantly.

Q: What are the implications of these findings?

A: The findings of this study have significant implications for forest conservation and management. The loss of primary forests is a major concern, as it can lead to the loss of biodiversity and ecosystem services. The increase in plantation land use also raises concerns about the impact on local communities and the environment.
