Introduction

Mangrove forests play a vital role in maintaining the health of coastal ecosystems and supporting the livelihoods of surrounding communities. However, these ecosystems are facing significant threats due to human activities such as deforestation, land conversion, and urbanization. This study aims to analyze the changes in the closure of mangrove forest areas in Percut Sei Tuan District, North Sumatra, between 2011 and 2014. The research used satellite imagery and guided classification methods to identify the extent of mangrove forest loss and the factors contributing to this decline.

Methodology

The study utilized satellite imagery from Landsat 7 and Landsat 8 to analyze the changes in land closure in Percut Sei Tuan District. The data was processed using guided classification methods to identify the extent of mangrove forest loss and the factors contributing to this decline. The study also collected data on the socio-economic factors influencing land use changes in the region.

Results

The results of the study show that the area of mangrove forest in Percut Sei Tuan District has experienced a relatively small decline between 2011 and 2014. In 2011, the area of mangrove forest was 3,672,849 hectares, while in 2014, the area was 3,672,299 hectares, representing a decrease of 0.55 hectares (0.0149%). However, this decline is significant and has the potential to have a major impact on coastal ecosystems and the lives of surrounding communities.

Factors Contributing to Mangrove Forest Loss

The study identified several factors contributing to mangrove forest loss in Percut Sei Tuan District, including:

Pond Development

The need for land for fisheries cultivation has encouraged the conversion of mangrove land into ponds. This has resulted in the loss of mangrove forests and the degradation of coastal ecosystems.

Oil Palm Plantations

The expansion of oil palm plantations is also an important factor in changes in land closure. The demand for palm oil has led to the conversion of mangrove forests into oil palm plantations, resulting in the loss of biodiversity and ecosystem services.

Development of Agricultural Land

Food needs have encouraged the conversion of mangrove land into rice fields. This has resulted in the loss of mangrove forests and the degradation of coastal ecosystems.

Settlement

Increased population and urbanization have encouraged the development of settlements in coastal areas, causing changes in the function of mangrove land. This has resulted in the loss of mangrove forests and the degradation of coastal ecosystems.

Impacts of Mangrove Forest Loss

The loss of mangrove forests has significant impacts on coastal ecosystems and the lives of surrounding communities. Some of the negative impacts include:

Coastal Erosion

Mangrove forests play an important role in holding abrasion and protecting the coastline. The loss of mangrove forests increases the risk of coastal erosion and damage to coastal infrastructure.

Decreased Water Quality

Mangrove forest functions as a water filter, so that the water that enters the sea remains clean. Damage to mangrove forests can cause a decrease in sea quality, which has an impact on the life of marine life.

Loss of Animal Habitat

Mangrove forest is an important habitat for various species of animals, both land and sea. The loss of mangrove forests results in loss of animal habitat and has the potential to threaten the sustainability of its population.

Community Economic Decline

Coastal communities, especially fishermen, are very dependent on mangrove ecosystems for livelihood sources. The loss of mangrove forests can threaten the livelihoods and the economy of the community.

Mangrove Preservation Efforts

Various efforts need to be made to preserve mangrove forests and prevent damage, such as:

Increasing Public Awareness

It is important to increase public awareness about the importance of mangrove forests and the negative impact of the damage.

Application of Pro-Mangrove Policies

The government needs to implement policies that support the preservation and rehabilitation of mangrove forests.

Community-Based Program Development

Community-based programs such as mangrove planting and mangrove forest management in a sustainable manner can increase community participation in preservation efforts.

Conclusion

Changes in the closure of mangrove forest areas in Percut Sei Tuan District, although relatively small, remain a serious concern. This study shows that the development of ponds, oil palm plantations, agricultural land, and settlements is a major factor in changing the closure of mangrove land in this region. It is essential for the government and the community to work together in preserving mangrove forests to maintain the sustainability of coastal ecosystems and the welfare of the community.

Recommendations

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

The government should implement policies that support the preservation and rehabilitation of mangrove forests.
Community-based programs such as mangrove planting and mangrove forest management in a sustainable manner should be developed and implemented.
Public awareness about the importance of mangrove forests and the negative impact of the damage should be increased.
The development of ponds, oil palm plantations, agricultural land, and settlements should be regulated to prevent the loss of mangrove forests.

By implementing these recommendations, the government and the community can work together to preserve mangrove forests and maintain the sustainability of coastal ecosystems and the welfare of the community.

Introduction

Mangrove forests are one of the most unique and valuable ecosystems on the planet. They provide a home for a diverse array of plants and animals, protect coastlines from erosion, and support the livelihoods of millions of people. However, mangrove forests are facing significant threats due to human activities such as deforestation, land conversion, and climate change. In this article, we will answer some of the most frequently asked questions about mangrove forests and their importance.

Q: What are mangrove forests?

A: Mangrove forests are coastal ecosystems that are dominated by mangrove trees, which are adapted to living in saltwater environments. They are found in tropical and subtropical regions around the world and are characterized by their unique root systems, which help to stabilize the soil and protect the coastline from erosion.

Q: Why are mangrove forests important?

A: Mangrove forests are important for a variety of reasons. They provide a home for a diverse array of plants and animals, including many species that are found nowhere else on Earth. They also protect coastlines from erosion, support the livelihoods of millions of people, and help to mitigate the impacts of climate change.

Q: What are the main threats to mangrove forests?

A: The main threats to mangrove forests are deforestation, land conversion, and climate change. Deforestation occurs when mangrove forests are cleared for agriculture, urbanization, or other human activities. Land conversion occurs when mangrove forests are converted into other types of ecosystems, such as salt pans or aquaculture. Climate change is also a major threat to mangrove forests, as rising sea levels and increased storm intensity can damage or destroy mangrove forests.
