Mapping Changes in Land Cover in the Coast of Medan City and Deli Serdang Regency: A Study on Environmental Dynamics

Introduction

The coastal areas of Medan City and Deli Serdang Regency in North Sumatra, Indonesia, are facing significant changes in land cover due to various human activities. The rapid growth of urbanization, agriculture, and settlements has led to the degradation of natural habitats, including mangrove forests and swamps. This study aims to examine the changes in land cover in the coastal areas of Medan City and Deli Serdang Regency using satellite imagery and geographical information systems (GIS). By analyzing the changes in land cover, this study hopes to provide insights into the environmental dynamics of the region and inform strategies for sustainable land use and conservation.

Background

The coastal areas of Medan City and Deli Serdang Regency are characterized by a diverse range of land cover types, including swamps, mangroves, mixed gardens, settlements, plantations, dry land agriculture, wetland agriculture (rice fields), ponds, and water bodies. The region is also home to a rich biodiversity, with many species of plants and animals depending on the coastal ecosystems for their survival. However, the rapid growth of human activities in the region has led to significant changes in land cover, with many areas being converted into settlements, agriculture, and other human-dominated land uses.

Methodology

This study used satellite imagery from the Landsat ETM 7 sensor in 2002, 2006, and 2009 to analyze the changes in land cover in the coastal areas of Medan City and Deli Serdang Regency. The satellite imagery was processed using a GIS to determine the type of land cover and calculate the area of each land cover type. The study grouped the coastal areas into nine categories: swamps, mangroves, mixed gardens, settlements, plantations, dry land agriculture, wetland agriculture (rice fields), ponds, and water bodies.

Analysis of Land Cover Changes

The results of the study showed significant changes in land cover in the coastal areas of Medan City and Deli Serdang Regency between 2002 and 2009. One of the main findings was the degradation of swamp shrubs, which switched into settlements, dry land agriculture, and ponds. This indicates an increase in human activity in the region, which has the potential to threaten coastal ecosystems. The decline in the area of mangrove forests is also striking, with many areas being converted into swamps, settlements, and ponds. Mangrove forests play an important role in protecting the coast from abrasion and providing a habitat for various species.

Impact of Land Cover Changes

The changes in land cover in the coastal areas of Medan City and Deli Serdang Regency have significant impacts on the environment and human communities. The decline in mangrove forest cover reduces biodiversity and increases coastal vulnerability to climate change and natural disasters. The increase in settlements and agriculture also leads to pollution and habitat damage, which can have negative impacts on human health and well-being.

Conclusion and Recommendations

In conclusion, this study highlights the importance of monitoring and analyzing changes in land cover in the coastal areas of Medan City and Deli Serdang Regency. The results of the study show significant changes in land cover, with many areas being converted into settlements, agriculture, and other human-dominated land uses. To address these changes, it is essential to implement sustainable policy and conservation efforts, particularly in protecting the area of mangrove forests and swamps. Community education and awareness-raising programs are also necessary to reduce the negative impacts of land expansion and promote sustainable land use practices.

Recommendations for Future Research

This study provides a foundation for future research on the environmental dynamics of the coastal areas of Medan City and Deli Serdang Regency. Future studies should focus on:

  • Monitoring changes in land cover and land use patterns in the region
  • Analyzing the impacts of land cover changes on coastal ecosystems and human communities
  • Developing and implementing sustainable policy and conservation efforts to protect the coastal environment
  • Raising awareness and promoting education among local communities on the importance of maintaining the balance of coastal ecosystems

Limitations of the Study

This study has several limitations, including:

  • The use of satellite imagery from a single sensor (Landsat ETM 7) may not capture the full range of land cover changes in the region
  • The study only analyzed changes in land cover between 2002 and 2009, and future studies should examine changes over a longer period
  • The study did not account for the impacts of climate change on land cover changes in the region

Future Directions

This study provides a foundation for future research on the environmental dynamics of the coastal areas of Medan City and Deli Serdang Regency. Future studies should focus on developing and implementing sustainable policy and conservation efforts to protect the coastal environment, as well as raising awareness and promoting education among local communities on the importance of maintaining the balance of coastal ecosystems.
